Elon Musk's Unbelievably Simple Killer Break Down on Climate Change
The basics of climate change.
Elon Musk breaks down climate change for students at The Sorbonne in Paris right before the historic COP21 Climate Change Conference in which 170+ nations signed to reduce carbon emissions below 2C, and preferably under 1.5C.
This is one of the best basic explanations on climate change ever given in a short amount of time. Enjoy!

Re: Elon Musk's Unbelievably Simple Killer Break Down on Climate Change
Nearly two years ago.
Anything more recent?
Climate change is a reality. Climate is changing all the time as we know from the pre-industrial Medieval Warming Period.
But anthropogenic global warming? "Prove it!" would be my response. This seems to have been a remarkably cold year so far. The Pacific islands that were supposed to be drowning are shown to be increasing in land area.
This is a non-issue in any case as carbon based fuels (apart from rockets perhaps, ironically) will be dead within 20 years replaced by solar, wind energy and cheap battery storage.
There have been no disastrous effects of the alleged AGW so far unless you are going to include an increase in biomass on planet Earth supporting more flora and fauna. In fact the world economy has been growing at a huge rate and there has been a massive decrease in poverty since this scare first got going.

Yes. Will this be enough or would you like more recent science based information?
In fairness let me first present an opposing viewpoint by the leader.

Long-term warming trend continued in 2017: NASA, NOAA
From NASA
Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA.
Continuing the planet's long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. That is second only to global temperatures in 2016.
In a separate, independent analysis, scientists at the National Oceanic and Atmospheric Administration (NOAA) concluded that 2017 was the third-warmest year in their record. The minor difference in rankings is due to the different methods used by the two agencies to analyze global temperatures, although over the long-term the agencies’ records remain in strong agreement. Both analyses show that the five warmest years on record all have taken place since 2010.
Because weather station locations and measurement practices change over time, there are uncertainties in the interpretation of specific year-to-year global mean temperature differences. Taking this into account, NASA estimates that 2017’s global mean change is accurate to within 0.1 degree Fahrenheit, with a 95 percent certainty level.
“Despite colder than average temperatures in any one part of the world, temperatures over the planet as a whole continue the rapid warming trend we’ve seen over the last 40 years,” said GISS Director Gavin Schmidt.
The planet’s average surface temperature has risen about 2 degrees Fahrenheit (a little more than 1 degree Celsius) during the last century or so, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Last year was the third consecutive year in which global temperatures were more than 1.8 degrees Fahrenheit (1 degree Celsius) above late nineteenth-century levels.
Phenomena such as El Niño or La Niña, which warm or cool the upper tropical Pacific Ocean and cause corresponding variations in global wind and weather patterns, contribute to short-term variations in global average temperature. A warming El Niño event was in effect for most of 2015 and the first third of 2016. Even without an El Niño event – and with a La Niña starting in the later months of 2017 – last year’s temperatures ranked between 2015 and 2016 in NASA’s records.
In an analysis where the effects of the recent El Niño and La Niña patterns were statistically removed from the record, 2017 would have been the warmest year on record.
Weather dynamics often affect regional temperatures, so not every region on Earth experienced similar amounts of warming. NOAA found the 2017 annual mean temperature for the contiguous 48 United States was the third warmest on record.
Warming trends are strongest in the Arctic regions, where 2017 saw the continued loss of sea ice.
NASA’s temperature analyses incorporate surface temperature measurements from 6,300 weather stations, ship- and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.
These raw measurements are analyzed using an algorithm that considers the varied spacing of temperature stations around the globe and urban heating effects that could skew the conclusions. These calculations produce the global average temperature deviations from the baseline period of 1951 to 1980.
NOAA scientists used much of the same raw temperature data, but with a different baseline period, and different methods to analyze Earth’s polar regions and global temperatures.

GISS is a laboratory within the Earth Sciences Division of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The laboratory is affiliated with Columbia University’s Earth Institute and School of Engineering and Applied Science in New York.
NASA uses the unique vantage point of space to better understand Earth as an interconnected system. The agency also uses airborne and ground-based monitoring, and develops new ways to observe and study Earth with long-term data records and computer analysis tools to better see how our planet is changing. NASA shares this knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.

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.
