Climate Change - History and Forecasts

For SpaceNut .... there are numerous topics that contain the word "climate".

However, all I found seem to be focused on a particular aspect of the subject.

This new topic is offered for those who may wish to contribute to an accumulation of knowledge about the subject.

I am not looking for opinion in this topic.  We have a great number of topics where opinion is welcome and encouraged.

The opening post here is from an article by a historian who studied the Little Ice Age.  The purpose of the study was:

1) to see what happened (with focus on local variation around the planet)

2) to see how humans coped (many did NOT survive)

The author appears to be publishing in hopes citizens living today might be able to glean some insight from the past.

https://www.yahoo.com/news/small-climat … 45154.html

Nations and communities might learn from some of the success stories of the Little Ice Age: Populations that prospered were often those that provided for their poor, established diverse trade networks, migrated from vulnerable environments, and above all adapted proactively to new environmental realities.

People who lived through the Little Ice Age lacked perhaps the most important resource available today: the ability to learn from the long global history of human responses to climate change.

Re: Climate Change - History and Forecasts

People used to respond to climate and/or ecosystem change by relocating. Humans and hominids went north or south as the ice moved. People were able to move into the Americas from the north because of retreating glaciers allowing people to move through what is now Alaska.

Now people are more reluctant and in many cases (as far as international borders go) less able to move.

Re: Climate Change - History and Forecasts

You can migrate unless you have built fixed assets like cities.  Even moving farms is nontrivial.

Re: Climate Change - History and Forecasts

Climate change = global warming by another definition

If you bought and invest in property along the sea coast there is a good chance that its now or will be soon under water... Its that investment with no return for your life time of payments that is the loss that one can not afford. Lots of folks that invest in such items are looking to sell in the golden years in order to be financially set by the rise in value.

Re: Climate Change - History and Forecasts

SpaceNut and GW,

Given everything that real estate investors, bankers, politicians, and the general public knows or ought to know about living near large bodies of water that are subjected to repeated flooding events, with or without global warming, why are governments and banks still handing out money like candy to build there?

The messaging as it pertains to investing and new construction is not congruent at all.  We're proving through actions that we don't actually believe in what we claim to believe in, or we're utterly ignoring the consequences of poor decision making.

I think the sea will rise and flood this area, so I'm going to buy a multi-million dollar vacation home there, that the rest of the tax payers underwrite the flood insurance policy for.  That seems like non-existent planning for the future to me.

Re: Climate Change - History and Forecasts

I would agree on a case by case and there are buts...such as when we had the may day floods in back to back years where the hillside trench for water along the roadway over flowed and came down the hill into my home.. Now I am 400 to 600 feet above sea level but I still had flood condition occur...continue down the hill that I set on the slope and you end up with a flood plain that is probably at 300 ft due to springs and road run off. other wise its usually under natural control and no problems occur.
I guess the real quest for those that flood now is what level were they when those that bought in risk areas?

Re: Climate Change - History and Forecasts

Chinese coal consumption continues to grow.
https://oilprice.com/Energy/Coal/China- … Green.html

The Chinese are producing more coal than the entire rest of the world, from reserves that are half the size of those in the US.  And their consumption continues to grow, with coal prices soaring to unprecedented levels.  It looks more and more like desperation.  I wonder how long they can keep this up?

Whilst many people expect the Chinese to rule the world, they look to me to be approaching a peak in their power.  Their economy is increasingly pushing against resource limitations that will be very difficult to circumvent.  The next few decades will be interesting times.

Re: Climate Change - History and Forecasts

I saw on Facebook a couple people claimed the New Shepard launch by Blue Origin emitted pollution that contributes to climate change. I responded to one of them, telling him they use liquid hydrogen and liquid oxygen, exhaust is steam. That individual countered that water can cause global warming too. I said the water will come down as rain. He didn't believe that. Well, here's a video that high lights a BBC report on test firing the RS-25 engine at Stennis in preparation for SLS.

Re: Climate Change - History and Forecasts

FFS! Comparing the Little Ice Age - when steam power had hardly been invented - with now, when we have so many technologies at our disposal. It doesn't even begin to make sense.  One observation I would make is that the Little Ice Age did not impede in any way Europe's cultural, economic and social development.

Re: Climate Change - History and Forecasts

This going to be fun if it happens.  I have a SciFi movie about it that I tend to laugh about.  Maybe not so much now.  Maybe it is time to become a snow bird.

Re: Climate Change - History and Forecasts

To stop such a flow means the heat from the equator can no longer be cooled by the cold of the pole at the current flow rate of the gulf stream as it advances along its corridor. Since the polar area is getting warmer it impedes the rising heat slowing it as it try's to turn the corner to head back south. This is what is know as thermosyphon..

This is what we want to happen

here is what is happening

The portion that needs to go by Europe needs to be much greater and with the pressure pushing it to the areas around green land we are warming the pole...
