NASA’s longest running survey of ice shattered records in 2017
By Maria-José Viñas,
NASA's Earth Science News Team
February 13, 2018

Last year was a record-breaking one for Operation IceBridge, NASA’s aerial survey of the state of polar ice. For the first time in its nine-year history, the mission, which aims to close the gap between two NASA satellite campaigns that study changes in the height of polar ice, carried out seven field campaigns in the Arctic and Antarctic in a single year. In total, the IceBridge scientists and instruments flew over 214,000 miles, the equivalent of orbiting the Earth 8.6 times at the equator

“A big highlight for 2017 is how we increased our reach with our new bases of operations and additional campaigns,” said Nathan Kurtz, IceBridge’s project scientist and a sea ice researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “In the Arctic, we flew out of Svalbard for the first time, expanding our coverage of the Eastern Arctic Ocean. And with our two Antarctic aircraft campaigns from Argentina and East Antarctica, we’ve flown over a large area of the Antarctic continent.”

The expanding sets of measurements collected by IceBridge will continue to be invaluable for researchers to advance their understanding of how the Greenland and Antarctic ice sheets are contributing to sea level rise and how the changing polar sea ice impacts weather and climate. For example, in 2017, scientists worldwide published studies that had used IceBridge data to look at ways to improve forecasts of sea ice conditions and to use satellites to map the depth of the layer of snow on top of sea ice, a key measurement in determining sea ice volume.

Chinese Vice Premier Wang Yang meets with Tesla CEO Elon Musk in Beijing

Elon Musk made an unexpected visit to China this week. Late on Tuesday night, China’s official news agency tweeted a photo of the Tesla chief chatting with Vice Premier Wang Yang, one of the country’s top officials in charge of the economy, in what a close watcher of China’s automotive industry says may go down as a breakthrough meeting.

Tesla (tsla, +2.70%) is riding high in China. Sales there tripled to more than $1 billion last year, the company said in March. Vehicle exports to China rose 376% year-over-year in the first two months of 2017, according to researcher JL Warren Capital.

But Tesla remains far from making China its biggest market, which Musk had predicted could someday happen. The $1 billion in China revenue in 2016 compared to $4.2 billion in the U.S.

Which is why Musk’s latest photo opportunity is important. This is the first time the powerful Vice Premier Wang has ever met an automotive CEO like Musk alone, said Li Anding, Xinhua’s former automotive reporter who now consults automakers on releases in China.

“Wang usually meets with groups of people,” Li said. The one-on-one meeting sends a message of Tesla’s importance in China, whose politicians consider the California company a role model for the country’s new electric car companies, as many vehicles suffer from long charging times and a poor driving experience, he explained.

Li also predicts that the meeting means Tesla is moving closer to signing a joint venture with a Chinese automaker to produce cars locally. Today, 25% tariffs on Tesla’s imported cars inflate its sticker prices, despite the company charging the same for cars in China as it does in its home country. This stands in contrast to some of the German luxury makers, which have been accused of ripping off and overcharging consumers. A joint venture would likely improve Tesla’s affordability in China.

Li says it’s tough predicting the timing of a joint venture. But Tesla is in the midst of meeting potential partners from different Chinese cities, according to one high-level official from China’s auto lobby who spoke to Fortune. Musk’s meeting with Wang, a former leader of Guangdong province, throws fresh speculation on its potential partner, as Guangdong is one of China’s many automotive hubs.

Musk has appeared in lots of photos lately. But his latest shot coming out of China might be Tesla’s most important sighting in a while.

Elon Musk met with Erdogan to discuss Tesla's and SpaceX's cooperation with Turkish firms
Reuters
Nov. 8, 2017

ANKARA, Nov 8 (Reuters) - Turkish President Tayyip Erdogan and Tesla Inc chief executive Elon Musk met on Wednesday to discuss cooperation between Tesla, SpaceX and Turkish firms, Turkey's presidential spokesman said.

Musk, who is in Turkey to attend the Global SatShow in Istanbul, met Erdogan and Turkey's transportation and industry ministers at the presidential palace in Ankara.

Presidential spokesman Ibrahim Kalin said Musk and Erdogan discussed potential joint operations between Tesla Inc, Musk's SpaceX company and Turkish firms, as well as the launch of Turkey's Turksat 5A and 5B satellites.

"We also exchanged views on what sort of joint operations Turkish firms could have with the SpaceX and Tesla companies," Kalin was quoted as saying by the state-run Anadolu news agency.

Turkey aims to launch the Turksat 5A satellite in 2020 and the 5B in 2021. In October, Airbus submitted the best bid in a tender to build the Turkish satellites.

Kalin said an agreement would be signed with Airbus on Thursday, and Musk would also be present at the meeting as a subcontractor.

Musk's SpaceX plans its first trip to Mars in 2022, carrying only cargo, to be followed by a manned mission in 2024.

Kalin also said Erdogan and Musk had discussed electric cars, days after Turkey unveiled plans to launch a car made entirely in Turkey by 2021, which the president cast as a long-harboured dream of the Turkish people.

Elon Musk: 'If we are successful in this, it is game over for all the other heavy lift rockets'
by Kevin Loria
Feb. 5, 2018
Business Insider

If SpaceX's  Falcon Heavy launch on Tuesday is successful, CEO Elon Musk thinks the success will blow away the competition for launching heavy loads into space.

"If we are successful in this, it is game over for all the other heavy lift rockets," Musk said Monday evening on a press call.

The first launch is scheduled for 1:30 p.m. on Tuesday and will be  broadcast live. If it succeeds, the system will not only be cheaper than any other operational heavy launch vehicle, but it'll also be the most powerful (some retired rockets, like the Saturn V, were more powerful).

Musk believes that if the Falcon Heavy can successfully get  its very cool payload into space, it will no longer make sense to use other vehicles certified for  heavy lift launches, like the Delta IV Heavy, Russia's Proton, or Europe's Ariane 5. That's because of the same reason SpaceX's other rockets are already revolutionizing the business of getting to space — it's a lot cheaper to reuse the rocket boosters that propel something out of Earth's gravity well than to use new ones every time.

The  Falcon Heavy has three boosters attached to each Falcon 9 rocket, and SpaceX has become quite good at recovering them for refurbishment and reuse. Other existing launch systems can't recycle their boosters.

Future competitors, however, like  Jeff Bezos' Blue Origin, do plan on  using reusable rockets, matching SpaceX with that crucial capability.

The Falcon Heavy isn't the only high-powered rocket SpaceX has in the works — the company is also working on a system known  as the BFR, which it plans to certify for crewed missions. Musk said it was designed to be reused more quickly than the Falcon Heavy.

If SpaceX wanted to make Falcon Heavy even more powerful, according to Musk, the company could bring up the power pretty close to that of the Saturn V, the most powerful rocket in history. That's because Falcon Heavy essentially takes the Falcon 9 system, which SpaceX has now launched and landed quite a few times, and adds two identical first-stage boosters (which provide most of the rocket's thrust) to the sides of the central booster, cranking up the power.

"We could really dial it up to as much performance as anyone could ever want. If we wanted to, we could actually add two more side boosters and make it Falcon Super Heavy ... I think we can crank up thrust and probably get upwards of 9 million pounds of thrust," Musk said on the press call.

For now, it appears unnecessary for SpaceX to make a rocket that powerful. It would need extra testing and provide more power than what planned future Falcon Heavy missions would require.

With launch  scheduled for Tuesday and weather looking good, there's still a lot that could go wrong.

"It will be a real huge downer if it blows up, but ... if something goes wrong, hopefully it goes wrong far into the mission so we at least learn as much as possible along the way," Musk told Business Insider's space correspondent, Dave Mosher, on the call. "I'll be happy, I'll consider it a win if it clears the pad and doesn't blow the pad to smithereens."

If Falcon Heavy blows up the launchpad, rebuilding will take nine months to a year, Musk said. There are still plenty of ways for it to fail once it gets off the ground — the structure could be torn apart by supersonic shockwaves or the side boosters may not separate, since that system has never been tested, for example — but at that point, SpaceX could probably launch another Falcon Heavy within a few months.

A successful flight would prove that at least the initial design works. Musk seems hopeful.

"I'm sure we've done everything we could do to maximize the chance of success for this mission," he said.

"It's either going to be an exciting success or an exciting failure — one big boom. So I'd say tune in," Musk said. "It's going to be worth your time."

First Falcon Heavy launch blends SpaceX style, raw power and the unknown
February 5, 2018 Stephen Clark
Spaceflight Now.com

The Falcon Heavy will dispatch the Roadster — weighing around 2,760 pounds (1,250 kilograms) on the street — with enough velocity to escape Earth’s gravitational bonds, reaching a maximum speed of around 7 miles per second (11 kilometers per second; 24,600 mph).

The sports car will go into a “precessing Earth-Mars elliptical orbit around the sun,” SpaceX officials wrote in the mission’s press kit. The orbit will stretch beyond Mars’ average distance from the sun.

“We expect it’ll get about 400 million kilometers away from Earth, maybe 250 to 270 million miles, and be doing 11 kilometers per second,” Musk told reporters Monday. “It’s going to be in a precessing elliptical orbit, with one part of the ellipse being at Earth orbit the other part being at Mars orbit, so it’ll essentially be an Earth-Mars cycler.

“We estimate it’ll be in that orbit for several hundred million years, maybe in excess of a billion years. At times, it will come extremely close to Mars, and there’s a tiny, tiny chance that it will hit Mars,” he said.

Asked if SpaceX has quantified the chance of the Roadster impacting Mars, Musk replied: “Extremely tiny. I wouldn’t hold your breath.”

The Tesla Roadster’s weight and dimensions fall well under the Falcon Heavy’s capacity, and would not stress the lift capability of SpaceX’s smaller, single-core Falcon 9 rocket or Atlas, Delta and Ariane boosters operated by rivals United Launch Alliance and Arianespace.

The iconography surrounding Tuesday’s test launch has captured attention, but star of the show will be the Falcon Heavy itself, set to become the world’s most powerful launcher currently in service.

Comprised of three rocket booster cores derived from SpaceX’s operational Falcon 9 rocket, plus a single-engine upper stage, the Falcon Heavy can generate 5.1 million pounds of thrust in future configurations. On Tuesday’s demo flight, the average thrust from the Falcon Heavy’s 27 kerosene-fueled Merlin 1D engines will be throttled back to 92 percent power, equivalent to roughly 4.7 million pounds, Musk said.

That will surpass the European Ariane 5 launcher, the world’s leader in liftoff power at 2.9 million pound of thrust from two segmented solid rocket boosters and a core engine. SpaceX’s new rocket will produce more thrust than any launch vehicle since the space shuttle, and its power at liftoff — approximately the same thrust as 18 Boeing 747 jumbo jets — will come in fourth among rockets all time, after the Soviet Union’s N1 moon rocket, which never had a fully successful flight, NASA’s Saturn 5 launcher that carried astronauts to the moon, Russia’s 1980s-era Energia rocket and the space shuttle.

The Falcon Heavy will also be able to carry more payload into orbit than any other rocket in the world — and the most by any launcher since the Saturn 5 — a more important measure of the rocket’s lifting capacity.

The Delta 4-Heavy rocket, the most capable rocket in service today in terms of lift capacity, can haul up to 62,540 pounds (28,370 kilograms) to a low-altitude orbit approximately 120 miles (200 kilometers) above Earth when launched to the east from Cape Canaveral, according to a launch vehicle data sheet published by ULA.

NASA’s planned Space Launch System, set for a maiden flight in late 2019 or early 2020, will carry more than 154,000 pounds (70,000 kilograms) to low Earth orbit and produce a maximum thrust of 8.8 million pounds. A souped-up model of the SLS with an enlarged upper stage launching in the early 2020s could haul more than 230,000 pounds (105 metric tons) to low Earth orbit.

The SLS is being designed with surplus space shuttle engine and booster components, and the space agency intends to use the multibillion-dollar mega-rocket to send astronaut crews to the moon, and eventually beyond.

When its first stage boosters are not recovered, SpaceX’s Falcon Heavy will be capable of delivering up to 140,660 pounds (63,800 kilograms) to low Earth orbit when launched to the east from Florida’s Space Coast, where rockets get a velocity boost from Earth’s rotation.

But SpaceX intends to land all three first stage boosters on the Falcon Heavy, eating into the rocket’s propellant reserves and reducing the weight it can loft into orbit.

A Falcon Heavy rocket flight sells commercially for around $90 million, according to SpaceX’s website. But a mission for NASA or the U.S. military, which levy additional requirements on their launch providers, is expected to go for $150 million or more.

A mission using ULA’s Delta 4-Heavy rocket costs at least twice that. A Delta 4-Heavy launch contract for NASA’s Parker Solar Probe awarded in 2015 was valued at $389 million.

Musk predicted the first Falcon Heavy has a 50 to 70 percent chance of full success, but the final outcome of Tuesday’s test flight will only be known more than six hours after liftoff.

“There’s so much that can go wrong here,” Musk told CBS News. “There are a lot of experts out there saying there’s no way you can do 27 engines, all at the same time, and not have something go wrong.

“You’ve got the booster-to-booster interaction, acoustics and vibration that haven’t been seen from any man-made device in a long time,” Musk said.

The Soviet-era N1 rocket had 30 engines, but Russian engineers had trouble getting all of the powerplants to work in unison. Engine vibrations, turbopump failures and fuel leaks led to four failed launch attempts.

By comparison, the Saturn 5 had five larger first stage engines.

Built at SpaceX’s headquarters in Hawthorne, California, the Falcon Heavy will encounter intense structural loads as it climbs to the east from the Kennedy Space Center and exceeds the speed of sound. The moment of maximum aerodynamic pressure, known as Max-Q, will be a major stress point.

The Falcon Heavy’s core stage was manufactured specifically for the test flight. Engineers stiffened the center core to take the loads of a Falcon Heavy launch.

The two side boosters were refurbished and modified after launching two earlier Falcon 9 flights, sending the Thaicom 8 communications satellite and a space station-bound cargo capsule toward orbit in May and July of 2016.

“Around Max-Q, that’s where the force on the rocket is the greatest, and that’s possibly where it could fail as well,” Musk said. “We’re a bit worried about ice potentially falling off the upper stage onto the nose cones of the side boosters. That could be coming like a cannon ball through the nose cones.”

“We’ve done all the (computer) modeling we could think of,” Musk told CBS News. “We’ve asked … third parties to double check the calculations, make sure we haven’t made any mistakes. So, we’re not aware of any issues, nobody has been able to point out any fundamental issues. In theory it should work. But where theory and reality collide, reality wins.”

The Falcon Heavy’s twin boosters will cut off their engines and fall away from the rocket around two-and-a-half minutes after liftoff, a separation sequence that has also never been tested in flight. The core stage, operating a lower throttle setting to conserve propellant and burn longer, will continue firing its nine engines until T+plus 3 minutes, 4 seconds.

“If it clears the pad and hopefully makes it throgh transonic and Max-Q, and the boosters are able to separate, it’s a more normal regime,” Musk said. “It becomes like a Falcon 9 at that point.”

The upper stage’s single Merlin engine will fire three times on Tuesday’s mission, continuing the demo flight’s experiments well after liftoff.

Meanwhile, the Falcon Heavy’s two strap-on boosters will flip around to fly tail-first with the aid of cold-gas nitrogen thrusters. Some of the engines on each booster will reignite for “boostback” and “entry” maneuvers to aim for two adjacent touchdown zones at Cape Canaveral Air Force Station around 9 miles (13 kilometers) south of pad 39A.

Like the Falcon 9’s first stage, the boosters will unfurl grid fins for added stability.

Twin sonic booms will crack across the spaceport as the boosters return to Cape Canaveral for staggered landings, slowed with the help of rocket thrust.

The rocket’s center core will head for touchdown on SpaceX’s drone ship positioned downrange in the Atlantic Ocean, with landing expected at T+plus 8 minutes, 19 seconds, approximately 20 seconds after the boosters arrive back on the ground at Cape Canaveral.

The second stage engine will shut down to conclude its first burn at around T+plus 8 minutes, 31 seconds. Another 30-second firing is programmed to start at T+plus 28 minutes, 22 seconds, to send the upper stage, its Tesla cargo and “Starman” into an orbit that ranges to a peak altitude tens of thousands of miles above Earth.

But the mission will not be over.

The rocket will keep flying, soaring through the Van Allen radiation belts before its engine reignites around six hours later for a departure maneuver into interplanetary space.

Musk said the extreme cold and radiation will present hazards during the six-hour coast, which is twice as long as any profile followed by a Falcon 9 rocket in the past.

“Even once we reach orbit we’ve got a very long coast, we’ve got a six-hour coast before restart, which is twice as long as we’ve ever coasted a stage, so we could see the fuel potentially freeze, because it’s out there in deep space, and when it’s not facing the sun it’s at three degrees above absolute zero,” Musk told CBS News. “So it could easily freeze, or the liquid oxygen could boil off, so there’s a lot that could go wrong.”

The upper stage “will actually be in a far worse radiation environment than deep space for several hours, survive that, and then re-light for the trans-Mars injection,” he said.

Long-duration upper stage flight profiles are required for the most demanding U.S. military launch missions, such as the placement of satellites directly into geostationary orbit, a circular perch more than 22,000 miles (nearly 36,000 kilometers) over the equator. Multiple, perfectly-timed engine burns are needed to move from an initial low-altitude inclined parking orbit into such a high-altitude equatorial position.

The lengthy upper stage flight Tuesday will try to demonstrate the Falcon rocket family’s capability to pull off such a feat, showcasing the performance to the Air Force and other prospective customers.

Musk said the upper stage carries additional battery power and pressurant gas for the extra operating time in space.

Musk unveiled the Falcon Heavy rocket in 2011, and proclaimed then the launcher would be ready for blastoff in 2013. SpaceX said it slowed development of the Falcon Heavy to focus on other projects, including the recovery of Falcon 9 rocket stages for reuse, and to resolve technical problems that destroyed two Falcon 9 rockets in 2015 and 2016, one in flight and another on the launch pad.

Musk announced in September his updated vision for settling Mars — SpaceX’s ultimate mission — and announced that his company is working on a giant new rocket dubbed the BFR that could send cargo and crew ships to the red planet, or perhaps the moon if a lunar base becomes reality.

SpaceX developed the Falcon Heavy to lift heavier payloads into space than the company’s Falcon 9 rocket, and to compete with other heavy-lifters for contracts to haul massive spacecraft for the U.S. military and NASA. The Falcon Heavy may also find a niche in deploying large commercial satellites, or launching clusters of smaller spacecraft to support the build-out of planned broadband communications networks.

“This rocket’s great for a lot of reasons,” Musk told CBS News. “It’s something that I think inspires the public. I’ve been asked, is this like Apollo? I’d say it’s not Apollo, but it’s arguably a prelude to a new Apollo, and it’s going to be the only heavy to super-heavy lift rocket in the world. This will be more than twice the thrust and capability of any other rocket currently flying. And if it reaches orbit, it will have the most payload of any rocket since the Saturn 5.

“You could actually send people back to the moon with the Falcon Heavy. You could, with orbital refueling, send people to Mars,” he said. “We think probably our next design, the BFR, is going to be ideal for interplanetary colonization and for establishing a large base on the moon and a city on Mars,” he said. “But this is a prelude to that. This is going to teach us a lot about what’s necessary to have a huge booster with a crazy number of engines.

“We finally have a major advancement in rocketry … I’m not sure whether this will be lost on people, whether they’ll appreciate it,” he said. “I hope they do, because the era of the very large rocket went away with Saturn 5 and with the space shuttle. I find it odd that the Falcon Heavy is twice the thrust of anything from Russia, China, Boeing, Lockheed or Europe. And I hope it encourages them to raise their sights.”

Going into Tuesday’s test flight, only three Falcon Heavy missions are confirmed in SpaceX’s backlog after the test launch: Two for commercial telecom companies Arabsat and ViaSat, and one for the Air Force. Another company, Inmarsat, has an option to launch a future satellite on a Falcon Heavy.

Some customers that reserved launches on SpaceX’s Falcon Heavy rocket switched their satellites to the smaller Falcon 9, which benefited from multiple thrust and performance upgrades to carry some payloads that originally required the triple-core rocket.

Inmarsat and Intelsat had planned launches on the Falcon Heavy, but both ended up flying their satellites on the Falcon 9. The ViaSat 2 satellite built to provide high-speed Internet access across the United States was supposed to launch on a Falcon Heavy, but the firm move its launch to a European Ariane 5 rocket, citing schedule worries. ViaSat retained its contract with SpaceX to launch a future satellite on a Falcon Heavy.

Musk told CBS News he was “giddy” on the eve of the Falcon Heavy’s first blastoff.

“I thought for sure something would delay us, we could have some issue we discovered on the rocket or maybe bad weather,” Musk said in a conference call with reporters Monday afternoon. “But the weather’s looking good, the rocket’s looking good, so it should be an exciting day. I’m looking forward to it.

“We’ll have a good time no matter what happens. It’s guaranteed to be exciting, one way or another. It’s either going to be an exciting success or an exciting failure. One big boom! I’d say tune in, it’s going to be worth your time.”

But he’s hopeful for success.

“We’ve done everything we can,” Musk said. “I’m sure we’ve done everything we could do to maximize the chances of success of this mission. I think once you’ve done everything you can think of and it still goes wrong, well, there’s nothing you could have done. But I feel at peace with that.”

Adam Schiff, the ranking Democratic Member of the House Intelligence Committee investigating the Trump administration, has joined the newly formed bi-partisan Planetary Science Congressional Caucus!  The following article was posted on the Planetary Society website:

Casey Dreier • February 5, 2018
Announcing the Planetary Science Congressional Caucus

I'm excited to share with you a major step forward for the support of space exploration in the U.S. Congress: the official formation of the new Planetary Science Caucus.

A caucus is a formal interest group made up of members of Congress. Having a caucus allows legislators form new relationships and organize a core voting block of political support for an important issue, in this case, planetary science and space exploration.

According the caucus' official charter, its goals are to:

◦"Find life in our lifetimes," by advancing federal policies that support the search for life in our solar system and beyond.

◦Raise awareness of the benefits to the U.S. economy and industrial base resulting from federal investment in space science, technology, exploration, and STEM education.

◦Support private industry, academic institutions, and nonprofits that support space science and exploration.

This is the first caucus devoted to planetary science in the history of the U.S. Congress. And I'm very proud to say that The Planetary Society played an active role in its creation.

The co-chairs of the caucus are Rep. John Culberson (R-TX) and Rep. Derek Kilmer (D-WA).

The Planetary Science Caucus will also be open to members of the Senate with Senator Gary Peters (D-MI), Cory Gardner (R-CO), Jeff Merkley (D-OR) and Maria Cantwell (D-WA) already signed up as original members.

Additional members in the House of Representatives include: Rep. Ami Bera (D-CA), Rep. Adam Smith (D-WA), Rep. Bill Posey (R-FL), Rep, Pramila Jayapal (D-WA), Rep. Jackie Speier (D-CA), Rep. Bill Foster (D-IL), Rep. Randy Hultgren (R-IL), Rep. Elizabeth Esty (D-CT), Rep. Nydia Velazquez (D-NY) and Rep. Adam Schiff (D-CA).

The caucus is planning a kickoff event later this May.

Donald "the goofus" Trump  Junior yesterday said:

"The problem is rather than being reasonable and coming to the table, they forced themselves further, and further and further left," Trump Jr. said during his "Watters' World" interview. "I mean, they are left of commie right now"

The Democrats are "left of commie"!!!??    So that would make them dark red commynist dogs"?

Trump also believes that left-wing commynist pinko's have taken over most mass media except for the Trump News Network, Faux News.

Trump and other nutcases call CNN the "Communist News Network"!   They love Faux News.

The temperature in Omolon, Russia rose from 88 below zero to 38 degrees, 126 degrees warmer, in just two weeks!   

The temperature in Siberia rose more than 100 degrees in two weeks
by Jason Samenow
Washington Post
January 31, 2018

As an antidote to the report of minus-88 degree weather in the Siberian outpost of Oymyakon earlier this month, we give you this: The temperature in a settlement just to its east was an astonishing 126 degrees warmer two weeks later.

The mercury in Omolon, Russia, reached its highest January temperature ever recorded Monday: a relatively toasty 38.4 degrees.

38 degrees doesn’t exactly sound like a day at the beach, but consider that it’s 64 degrees warmer than Omolon’s average high of minus-26 at this time of year.

Omolon is 540 miles east of Oymyakon, which was described as so cold “eyelashes freeze, frostbite is a constant danger, and cars are usually kept running even when not being used.”


In Oymyakon, the forecast high Tuesday was 17 degrees, not quite as balmy as Omolon, but still about 60 degrees warmer than its average high around minus-40, and 105 degrees warmer than it was two weeks ago.

Oymyakon has the reputation as being the coldest permanently occupied human settlement in the world.

The 500-some people in Oymyakon and 800-some people in Omolon are probably rejoicing in this relative thaw.

The mild weather can be traced to the development of an enormous, bulging zone of high pressure over eastern Russia (see top image). Mashable science editor Andrew Freedman called it “one heckuva monster” on Twitter.

Underneath this high pressure zone, models show temperature differences from normal exceeding 50 degrees over a broad area. Weather.US meteorologist Ryan Maue tweeted that these temperature anomalies are “off the charts.”

Strangely, this unusual warmth in Siberia could trigger a chain of events resulting in deep freeze over central and eastern North America.

As the high-pressure zone builds east over Alaska in the coming week, it will probably force the jet stream to crash south over North America in response — like a seesaw. This will, in turn, probably lead to colder-than-normal conditions over parts of the central and eastern United States.

It’s unclear, however, just how far south and east the cold will penetrate.

20180103_falcon-heavy-launch-pad.jpg

At long last, SpaceX is ready to send its mythical Falcon Heavy rocket on a test flight next week. It's a huge deal, even for a spaceflight company that routinely accomplishes huge deals. An operational Falcon Heavy will make SpaceX the proud owner of the most powerful rocket system since the Saturn V*, and opens up yet another corner of the launch industry to serious competition.

The main goal of the test flight is straightforward: launch something into space without blowing up. CEO Elon Musk, never one to settle for something boring like an inert block of concrete, decided the sacrificial payload would be his Tesla Roadster, aimed for a Mars-adjacent trajectory.

"I love the thought of a car drifting apparently endlessly through space and perhaps being discovered by an alien race millions of years in the future," he said on Twitter.

I'll break down the Tesla aspect of the launch in a followup story coming out Monday, and I'll also be in Florida covering the launch in person. My boss, Planetary Society CEO Bill Nye, is scheduled to make an appearance at the Kennedy Space Center visitor's center. The first launch window opens Tuesday, February 6 at 1:30 p.m. ET (18:30 UT).

So, about that rocket

The Falcon Heavy is essentially three of the company's Falcon 9 rockets bolted together in a row, a design that makes it outwardly similar to United Launch Alliance's Delta IV Heavy. For those not up-to-date on SpaceX nomenclature, "Falcon” is an homage to the Millennium Falcon from Star Wars, and "Heavy" simply means the rocket can carry heavy things to space.

SpaceX revealed the Falcon Heavy in 2011, predicting it would fly as early as late 2013. Musk is known for his ambitious timelines, and it turned out the rocket's design was more difficult to perfect than originally thought. Initially, SpaceX considered equipping the Heavy with a complicated propellant crossfeed system, in which the two side boosters re-fill the center booster as the rocket ascends. When the side boosters are empty, they drop away, leaving the center core with a full fuel tank. This ultimately makes the rocket more efficient.

The crossfeed feature ended up being too complex, but even without it, the Falcon Heavy was a challenge to bring to fruition. Whereas the Delta IV Heavy has just one engine for each of its three boosters, the Falcon Heavy has nine, for a grand total of 27 engines that must all ignite and work in tandem without tearing the rocket apart. SpaceX's two disasters in 2015 and 2016 delayed things further: the 2016 accident damaged the company's only launch pad, Space Launch Complex 40, forcing SpaceX to rush to get pad 39A operational. But since there's a chance the Heavy flight will end in disaster and damage pad 39A, SpaceX also needed to get pad 40 operational again.

There's actually a further bit of controversy surrounding this point. Only pad 39A is outfitted for crew flights, which are expected to start later this year (an ambitious timeline, according to the Government Accountability Office). Should the Falcon Heavy damage 39A, how will that affect NASA's commercial crew program, which has been waiting to launch astronauts from American soil since 2011? It's a fair question, and you can bet NASA officials will be watching this demo flight with clenched teeth.

On December 28, 2017, SpaceX raised the Falcon Heavy demo rocket into position at pad 39A for the very first time, and following a month of tests and tweaks, conducted a static fire on January 24.

SpaceX's website pegs the cost of a Falcon Heavy at $90 million. That number will get repeated a lot as the demo flight draws closer, so it's important to note it comes with some caveats. Buying a rocket is a little like buying a car: extra trim levels and extended warranties add up quickly and frequently put you above the starting price.

Case in point: Space Test Program-2 (STP-2), the Air Force launch that will carry multiple payloads to three different orbits, including The Planetary Society's LightSail 2 spacecraft. The Air Force will actually end up paying SpaceX a maximum of $160.9 million for that launch, depending on the completion of various milestones leading to launch, including mission success.

Here's why. First of all, there's oversight. The government requires its rocket providers to present lots of reviews as launch preparations progress. At those reviews, the provider updates Air Force officers and contracted, subject matter experts from organizations like The Aerospace Corporation on how things are going. If there are problems, deeper investigations may be required.

Secondly, STP-2 is a complex mission. 25 different spacecraft will be deployed into three different orbits. In addition to providing the Falcon Heavy rocket itself, SpaceX is responsible for designing and building the adapters to hold all those spacecraft inside the rocket's payload fairing, and also making sure they get deployed at exactly the right moments.

On STP-2 launch day, the Falcon Heavy will first place 12 satellites into an initial low-Earth orbit, before transferring to a circular, 720-kilometer circular, low-Earth orbit to deploy a constellation of six identical satellites called COSMIC-2, along with five smaller auxiliary payloads. (One of those auxiliary payloads is Prox-1, containing LightSail 2).

Then, the Falcon Heavy upper stage re-ignites and flies to an elliptical, medium-Earth orbit (12,000 by 6,000 kilometers), where it will drop off another spacecraft called DSX. After that, there's an Air Force certification objective to show the upper stage can coast for at least three, and ideally five, hours, before restarting for another five-second burn. To pull all of this off, SpaceX has to carefully configure the Falcon Heavy's flight software and test it to make sure it all works.

Even with all those extra options and requirements, the Falcon Heavy is still cheaper at $160.9 million than its competitors. A Delta IV Heavy flight can cross the $400 million threshold, and SLS will be even more expensive. (At one point NASA was hoping to keep the cost of an SLS flight to about a half-billion dollars, but that estimate has grown—how much depends on who you ask.)

SpaceX now routinely recovers and re-uses its Falcon 9 boosters by either flying them back to land or a drone ship in the Atlantic Ocean. For Falcon Heavy, SpaceX plans to recover all three of the Falcon Heavy's booster rockets. All three! The two side boosters will return to Cape Canaveral, and the center core will land on the drone ship Of Course I Still Love You.

There are a variety of possible outcomes for the demo flight: complete success, partial success, total disaster, loss of one or more boosters attempting to return to Earth, and the usual litany of everything that can go wrong during a rocket launch. In any case, it will be quite a thing to see.

If things go completely awry, it's unclear how soon SpaceX would continue marching through its Falcon Heavy manifest. Ultimately the big rocket is an interim solution; SpaceX plans to merge both the Falcon 9 and Falcon Heavy into a single, larger vehicle called BFR (Big Falcon Rocket, if you want to avoid expletives).

The company has already bounced back from two operational failures of its workhorse Falcon 9 rocket, so a disaster for this Falcon Heavy demonstration flight shouldn't be a huge setback—especially considering the low expectations Musk set. The only scenario that could cause the company significant problems would be if the Heavy badly damages the launch infrastructure at pad 39A and delays NASA's commercial crew program.

As far as I know, there's never been a rocket launch where the vehicle provider openly told the public there was a high chance things might end catastrophically. Succeed or fail, the demo flight is sure to be a blast!

Trump’s All-Out Attack on the Rule of Law
Accusing the FBI and DOJ of partisanship and conspiracies, the president is setting the stage for a constitutional crisis.
By Bob Dreyfuss
February 1, 2018
The Nation

With the imminent release of the jury-rigged “Nunes memo” and the resignation of FBI Deputy Director Andrew McCabe, who had been under fire from the president, Donald Trump and his Republican allies in Congress have expanded their all-out assault on the American system of justice, including the FBI, the Justice Department, the US intelligence community, and the Office of the Special Counsel. It’s an unprecedented attack on what Team Trump refers to as an imagined “Deep State,” a “secret society” within the FBI, and a conspiracy of judges, courts, and intelligence officials who have allegedly banded together to bring down his presidency.

There is of course a reality-based way to look at these events—namely, that the White House and the Trump campaign are under investigation by seasoned prosecutors and several congressional committees over plausible allegations that the president’s 2016 campaign colluded with or encouraged a Russian effort to influence the election’s outcome, and that since his inauguration Trump has engaged in a systematic effort to obstruct justice.

Over the past month or so, however, Trump’s obstruction efforts—as the president sees it, “you fight back, oh, it’s obstruction”—has kicked into high gear. At its center is a sustained White House–led attack on both special counsel Robert Mueller and the FBI, including several top FBI officials. Supporting Trump’s attack are the Republicans on the House Permanent Select Committee on Intelligence (HPSCI), who put together and then, on Monday, voted to release to the public a memorandum apparently designed to show that the FBI is partisan, pro-Democratic, and engaged in a broad conspiracy to undermine Trump’s presidency.

This is part of a broader pattern. Since taking office, Trump has targeted investigators, and other law-enforcement officials. He fired Acting Attorney General Sally Yates, who had informed him of Gen. Mike Flynn’s vulnerability to potential Russian blackmail. He ousted US Attorney Preet Bharara in New York (along with all the other Obama-appointed US Attorneys), who had overseen New York real-estate fraud and money-laundering investigations. He demanded FBI Director James Comey’s political loyalty, asked Comey to go easy on Flynn, and then fired Comey over, as Trump famously said on national television, “this Russia thing with Trump and Russia.” He made inappropriate requests of CIA Director Mike Pompeo, Director of National Intelligence Dan Coats, and NSA Director Mike Rogers, seeking their help in winding down the FBI investigation. He pressured his own attorney general, Jeff Sessions, not to recuse himself from the Russia inquiry, sharply criticized Sessions when he did, and then repeatedly slammed Sessions via Twitter and in media interviews, at one point indicating that he wanted Sessions gone. He repeatedly attacked Deputy Attorney General Rod Rosenstein, who has overseen the Russia inquiry since Sessions’s recusal. Last week, reports surfaced that Trump wants to get rid of Rosenstein, too. And Trump has explicitly attacked the entire FBI, saying that it’s “in tatters”—which received strong pushback from the man Trump himself appointed to lead the bureau, Director Christopher Wray. Wray himself threatened to resign over Trump’s uncalled-for attacks against the now-departed Deputy Director McCabe.

To most observers, Trump’s actions amount to a massive campaign to obstruct justice, one of the counts that Mueller is charged with looking into. Never before in American political history—not during Watergate, not during the Iran/Contra investigation in the 1980s, and not during the 1990s special prosecutor’s investigation of Whitewater—has a president so openly challenged the legitimacy of the entire justice system. Others have questioned the interpretation and meaning of evidence, but Trump and his GOP allies—backed in the right-wing media by the likes of Sean Hannity and Rush Limbaugh—have disparaged the patriotism, political neutrality, and professionalism of the entire US Justice Department, including the FBI, as well as the US intelligence community.

Apparently you think that anything to the left of the Ku Klux Klan and other right-wing terrorist organizations are run by communists!

So tell us which band or brand of "communist conspirators" have taken over the Cable News Network.   Are they Trotskyists, Stalinists, Maoists, Castroists or old school Bolsheviks?

And how did they pull that off without anyone, excepting you of course, aware of that!

How can any serious person believe any of your political propaganda in light of your constant assaults on the truth and smear jobs?

It it talks like a Trumpeter, lies like a Trumpeter, smears like a Trumpeter and ignores facts like a Trumpeter it is a Trumpeter.

So Mr. Trumpeter I won't waste anymore time responding to your counterfeit patriotism,  hateful posts and defense of the bigoted un-American criminal in the White House.   Lock him up!

Bill Nye Does Not Speak for Us and He Does Not Speak for Science
By attending the State of the Union with NASA administrator nominee Jim Bridenstine, the Science Guy tacitly endorses climate denial, intolerance and attacks on science
By 500 Women Scientists January 30, 2018
Scientific American

Tonight, Bill Nye “The Science Guy” will accompany Republican Rep. Jim Bridenstine (R-OK), Trump’s nominee for NASA Administrator, to the State of the Union address. Nye has said that he’s accompanying the Congressman to help promote space exploration, since, he asserts, “NASA is the best brand the United States has” and that his attendance “should not be … seen as an acceptance of the recent attacks on science and the scientific community.”

But by attending the SOTU as Rep. Bridenstine’s guest, Nye has tacitly endorsed those very policies, and put his own personal brand over the interests of the scientific community at large. Rep. Bridenstine is a controversial nominee who refuses to state that climate change is driven by human activity, and even introduced legislation to remove Earth sciences from NASA’s scientific mission. Further, he’s worked to undermine civil rights, including pushing for crackdowns on immigrants, a ban on gay marriage, and abolishing the Department of Education.

As scientists, we cannot stand by while Nye lends our community’s credibility to a man who would undermine the United States’ most prominent science agency. And we cannot stand by while Nye uses his public persona as a science entertainer to support an administration that is expressly xenophobic, homophobic, misogynistic, racist, ableist, and anti-science.

Scientists are people, and in today’s society, it is impossible to separate science at major agencies like NASA from other pressing issues like racism, bigotry, and misogyny. Addressing these issues should be a priority, not only to strengthen our own scientific community, but to better serve the public that often funds our work. Rather than wield his public persona to bring attention to the need for science-informed policy, Bill Nye has chosen to excuse Rep. Bridenstine’s anti-science record and his stance on civil rights, and to implicitly support a stance that would diminish the agency’s work studying our own planet and its changing climate. Exploring other worlds and studying other planets, while dismissing the overwhelming scientific evidence of climate change and its damage to our own planet isn’t just dangerous, it’s foolish and self-defeating.

Further, from his position of privilege and public popularity, Bill Nye is acting on the scientific community’s behalf, but without our approval. No amount of funding for space exploration can undo the damage the Trump administration is causing to public health and welfare by censoring science. No number of shiny new satellites can undo the racist policies that make our Dreamer colleagues live in fear and prevent immigrants from pursuing scientific careers in the United States. And no new mission to the Moon can make our LGBTQ colleagues feel welcome at an agency run by someone who votes against their civil rights.

As women and scientists, we refuse to separate science from everyday life. We refuse to keep our heads down and our mouths shut. As someone with a show alleging to save the world, Bill Nye has a responsibility to acknowledge the importance of NASA’s vast mission, not just one aspect of it. He should use his celebrity to elevate the importance of science in NASA’s mission—not waste the opportunity to lobby for space exploration at a cost to everything else.

The true shame is that Bill Nye remains the popular face of science because he keeps himself in the public eye. To be sure, increasing the visibility of scientists in the popular media is important to strengthening public support for science, but Nye’s TV persona has perpetuated the harmful stereotype that scientists are nerdy, combative white men in lab coats—a stereotype that does not comport with our lived experience as women in STEM. And he continues to wield his power recklessly, even after his recent endeavors in debate and politics have backfired spectacularly.

In 2014, he attempted to debate creationist Ken Ham—against the judgment of evolution experts—which only served to allow Ham to raise the funds needed to build an evangelical theme park that spreads misinformation about human evolution. Similarly, Nye repeatedly agreed to televised debates with non-scientist climate deniers, contributing to the false perception that researchers still disagree about basic climate science. And when Bill Nye went on Tucker Carlson’s Fox News show to "debate" climate change in 2017, his appearance was used to spread misinformation to Fox viewers and fundraise for anti-climate initiatives.

Bill Nye does not speak for us or for the members of the scientific community who have to protect not only the integrity of their research, but also their basic right to do science. We stand with others who have asked Bill Nye to not attend the State of the Union. Nye’s complicity does not align him with the researchers who have a bold and progressive vision for the future of science and its role in society.

At a time when our ability to do science and our ability to live freely are both under threat, our public champions and our institutions must do better.

https://blogs.scientificamerican.com/ob … r-science/


---------------------------------------------------------------------------------------------------------------------------------------

Bill Nye defended his attendance at the Trump speech declaring:   "At the State of the Union address, I hope to hear the President present plans for an ambitious, science-driven space exploration agenda. Space exploration brings out the best in us. It brings the nation together as we solve problems that have never been solved before and learn more about the cosmos and our place within it."

So what did Trump say about NASA and his space exploration agenda in his one hour and twenty minute speech?   Not a word.  Total silence. Let's see if Bill Nye responds to Trump's failure to address this scientific matter in his State of the Union speech.   I hope Nye does.

Industry & Technology/January 29, 2018
Opinion: The Zuma Fiasco
by Michael Weinhoffer/Staff Reporter

That was supposed to be a routine launch for SpaceX on Jan. 8 was anything but that. SpaceX has a much more significant launch very shortly with the debut of the Falcon Heavy, but the most recent launch overshadowed it for a few weeks. The classified mission did not go off too smoothly, and it provided  an opportunity to think about   the disadvantages of such missions.

Northrop Grumman, one of the largest defense contractors in the world, manufactured the payload for this launch. The company produced a spacecraft for the U.S. government, and since SpaceX has become authorized to launch military spacecraft and had flawless flights last year, it makes sense that they chose SpaceX as the launch provider. The only thing special about this flight is that virtually no one knows what the payload is. Someone deep inside the caverns of the Pentagon does, but not even the National Reconnaissance Office (NRO), which is responsible for overseeing all classified U.S. satellites, claimed responsibility for the payload, codenamed “Zuma.”

Zuma was supposed to launch on a Falcon 9 on Nov. 15 but was delayed almost two months as the SpaceX team analyzed payload fairing data from a previous customer. The launch on Jan. 8 went off without any problems, and SpaceX routinely landed the first-stage booster back at Cape Canaveral. They did not show live video of the second stage or payload deployment, but this was the custom when they launched other national security payloads. There was no confirmation that the payload made it into orbit by either SpaceX or Northrop Grumman, which was not too surprising, as that is the same routine for U.S. spy satellites.

However, the next day, the Wall Street Journal reported that the satellite failed to reach orbit and plummeted into the Indian Ocean. Congressional staffers and lawmakers informed them of this. Other news outlets concurred with the Wall Street Journal, but SpaceX and Northrop Grumman pushed back. Northrop Grumman said that they do not comment on classified missions; however, SpaceX’s comment was more interesting. Gwynne Shotwell, Chief Operating Officer and President of SpaceX, responding to calls for an explanation, said, “…Falcon 9 did everything correctly on Sunday night…Information published that is contrary to this statement is categorically false…” That is a reasonably strongly worded statement from SpaceX. If the payload did not reach the proper orbit, they surely are not taking any blame for it! It seems rather unlikely that the second stage of the Falcon 9 failed, but that means that the payload did not separate correctly from the rocket. Grumman did provide the payload adapter, which connects the payload to the rocket. That is usually something implemented by the launch provider, which tells me that Zuma was not an ordinary satellite or a satellite at all. If it were, the adapter provided by SpaceX would have suited it well. So maybe the payload adapter failed to release Zuma into orbit. That seems more likely. The consensus became the payload failed to reach its orbit one way or another.

Several news outlets reported that the payload crashed into the Indian Ocean, but a lack of evidence questions that conclusion. At this point, it is just pure speculation. Officials could have easily said that the payload failed to stop questions about its mission. What made things worse was at a Pentagon briefing, where someone asked about whether the precious payload was successful in reaching orbit. The government official taking questions responded by referring questions on the mission back to SpaceX! The launch provider, the payload manufacturer, and the U.S. government all have failed to comment on the status of the mission. I do not recall any space mission that had this level of classification.

So what is Zuma? News channels have called Zuma a “satellite,” and that seems likely because that is the most common payload of any launch, but there are other possibilities. As stated previously, the fact that Northrop Grumman provided the payload adapter themselves makes me think that Zuma is not a satellite. If it were, why not use SpaceX’s extremely reliable adapter? Let’s examine a few possibilities. The Air Force has the X-37B spaceplane, which is not a spy satellite, but rather a mini space shuttle that is conducting scientific experiments while in orbit. Those are classified missions, but it is nothing threatening. Zuma could be an experimental spaceplane like the X-37B, or it could be “something else.” The “something else” option is the most concerning. The only option that I can think of besides a satellite or a spaceplane is a weapons system. Zuma could be a laser weapon or a missile defense system that fires physicals projectiles at Earth.

There are no bans on weapons in outer space, but that does not mean that it is a good idea to put them there. Russia and China have pushed for the U.S. to back a U.N resolution that works to prevent a weapons buildup in outer space. The U.S. has refused, citing definition ambiguity and national security interests. Russia, China, and the U.S. all have tested space weapons and even launched missiles from Earth to destroy satellites in space. Outer space has become a strong military environment, and the question of whether to ban space weapons is still up for debate.

Launching highly classified payloads into outer space does not help those in opposition to the proposed resolution. A vital element of appropriate conduct in outer space is data transparency. Not knowing the purpose of a payload circling the Earth every ninety minutes puts nations on edge, and I am confident that Russia and China are very upset over the Zuma launch. There is no reason for a company such as Grumman to launch payloads with a higher classification than U.S. spy satellites. It is not appropriate conduct, and the U.S. should not repeat it. The United States needs to serve as a model of international cooperation and transparency in outer space, and this mission does not fulfill that standard. Frankly, I hope the payload did fail. I do not want to go to bed at night wondering if the Zuma payload is a threat to international security and the safety of outer space. The Zuma payload is not in the interest of international security and peace that has existed in outer space for more than fifty years and should not have successors.

Global Warming Stirs the Methane Monster
by Robert Hunziker
Counterpunch

It’s January, yet methane hydrates in the Arctic are growling like an incensed monster on a scorching hot mid-summer day. But, it is January; it’s winter, not July!

On January 1st Arctic methane at 2,764 ppb spiked upwards into the atmosphere, which, according to Arctic News: “Was likely caused by methane hydrate destabilization in the sediments on the seafloor of the Arctic Ocean.” (Source: Unfolding Arctic Catastrophe, Arctic News, January 2, 2018) Once again, with emphasis, it’s January; it’s winter, and there’s little or no sunshine above the Arctic Circle. So, what gives? Why are alarming levels of methane spewing into the atmosphere in the dead of winter?

For starters, record low sea ice volume, which has been dropping like a leaden weight for years because of human-generated (anthropogenic) global warming. That’s a recipe for trouble, big time trouble as methane hydrates (lattices of ice that entrap methane molecules) get exposed to warmer water. In that regard, average sea ice volume throughout 2017 was at record lows.

Making matters worse yet, extraordinarily warm water currents flow into the Arctic from nearby ocean waters that have been absorbing 90% of global warming. Ergo, Arctic water in thin ice does not cool down without a lot of thick ice to melt the warm water currents. So, abnormally warm water remains into winter months and, in time, reaches sediments at the bottom of the ocean, disrupting methane hydrates, which have stored tonnes of methane over millennia. However, in due course, all hell breaks loose with large-scale methane eruptions, one of those “Naw, it can’t be happening” moments.

Here’s the problem: On average, sea surface temps were 23.35°F warmer during the period October 1 to December 30, 2017 compared to the 30-year average temperature. On October 25th, the sea surface was as warm as 63.5°F. For the Arctic, that’s hot, not just warmer. And, that brings forth a big-gulp question: What’s going to happen in summertime when methane hydrates are more exposed?

After all, methane (CH4) is a dominating greenhouse gas that makes carbon dioxide (CO2) look like a piker during initial years and packs the walloping risk of runaway global warming, which, in turn, threatens agricultural sources of food… not a good scenario. Imagine the chaos, considering the fact that “runaway” means totally out of control!

In all, an impending disaster seems destined to happen, but nobody knows when. It will likely occur unexpected by an ill advised, crass, blundering, philistine society blindsided by a scorched planet and extensive loss of foodstuff. Chaos spreads throughout when all of a sudden, unexpectedly, crops fail. One bad crop season follows another and another. For example, Syria, where its 2006-11 devastating drought caused 75% of Syria’s farms to fail and 85% of livestock to die. That’s a wipeout!

In the end, as crops fail, it’s too late to take remedial action beyond dealing with dystopian warring factions locked in bloodthirsty combat over morsels of foodstuff.

Not only that, one more nasty early warning sign of trouble is right around the corner: The National Snow & Ice Data Center (NSIDC) January 3rd year-end headline reads: “Baked Alaska and 2017 in Review,” stating: “… notably high temperatures prevail over most of the Arctic, especially over Central Alaska.” That’s permafrost country! That’s where tonnes and tonnes and tonnes of methane lies in-waiting to spring loose into the atmosphere. After all, global warming is the kissing cousin to methane buried in permafrost.

And, of equivalent concern on a worldwide basis: “In 2016 – now and at least for another year, the hottest year on record – global sea ice extent suffered a precipitous drop, plummeting from a fairly average 2015 value to a new record low. Now, as we wrap up 2017, data from the US National Snow and Ice Data Center (NSIDC) shows that annual average global sea ice extent has dropped again, hitting an even lower record value.” (Source: Global Sea Ice Hits New Record Low for 2nd Year Straight, The Weather Network, January 8, 2017)

Meantime, the two poles, north and south, are in the early stages of collapse. Scientists know it, and there is lots of chatter about geo-engineering and assorted methodologies to fix anthropogenic global warming before it consumes civilization in a fireball, but those proposals are in dreamland for the moment. Hopefully, one of their fixit ideas works “to scale” because the planet is likely too big for geo-engineering schemes to work without some kind of unintended consequence, which may be worse than the original fix. In fact, nobody really knows for sure what will happen when the biosphere is forced to behave according to computer-designed plans. It’s an enormous undertaking!

Therefore, it is recommended that today’s push-button, screen-watching youth learn survival skills rather than playing games for hours on end, endlessly, moronically pre-occupied with electronic fantasylands, because one day in the near future that fantasy turns to harsh reality, likely hitting hard, really hard.

After all, eco-migrants, numbering tens of thousands, are already worldwide phenomena, especially along the southern and eastern Mediterranean Sea regions, where land is turning bone dry faster than anywhere else on the planet. It’s the start of the Great Global Warming Migration scenario… but, pray tell, where to?

Trump's view that ice caps 'setting records' baffles scientists
By Alister Doyle
January 29, 2018

Scientists puzzled on Monday over U.S. President Donald Trump's assertion that ice caps are "setting records" when much of the world's ice from the Alps to the Andes is melting amid global warming.

Trump cast doubt on mainstream scientific findings about climate change in an interview aired on Britain's ITV channel on Sunday night, saying "there's a cooling and there's a heating".

"The ice caps were going to melt, they were going to be gone by now. But now they're setting records. They're at a record level," he said.

Many people use the term "ice cap" to refer to polar sea ice or vast ice sheets on Greenland and Antarctica. It is also a technical term for smaller masses of ice on land, ending in glaciers.

"Glaciers and ice caps are globally continuing to melt at extreme rate," said Michael Zemp, director of the World Glacier Monitoring Service which tracks hundreds of glaciers.

Trump's implication that glaciers and ice caps are growing "is simply wrong. Or maybe he is referring to a different planet," Zemp said.

But seriously, several things we can do to combat global warming. These are actually effective, and don't do economic harm like a carbon tax or cap-and-trade system:

  • Kill the long-haul trucking industry. Use rail instead.

Railroads can't pick up and deliver LTL freight for long haul.   

Trucking companies and owner-operators handled over 10 billion tons of freight and 70% of all freight shipped last year.

The shrinking U.S rail freight industry doesn't have the rolling stock and locomotive fleet to handle that amount of additional freight.   And the railroads simply don't have railroad tracks giving them direct access to the hundreds of thousands of shippers that the trucking companies do have access to.

And it would cost hundreds of billions of dollars that the government and railroads won't invest to rebuild the kind of profitable freight train system you advocate.

If that was feasible, the railroad owners would have done that already.    They have a good nose for profit making ventures.

What kinds of actions should humans and their governments take to fight this world-wide "global cooling"?   I for one will do my best to increase carbon dioxide emissions.   We could all stop car pooling and perhaps have a national "Let Our Cars Idle All Day".   That would help   .Perhaps we need to build many more coal burning energy plants and end solar and wind powered energy production to at least slow down this global cooling danger.

The snow storms in the east and cold weather at the North Pole are a clear indications that we are entering a new ice age.
