Win, thanks for those links. Cyberspace is great! Instant clicks to the dinkum oil. Knowledge and thinking are the two most valuable things people do and we have had a quantum leap of amazing proportions with the creation and development of cyberspace.

This graph shows that we have started burning hydrocarbons just in time to avoid the plunge down into another ice age. nicl-smo.sr.unh.edu

Check the blue line temperatures. One of them shows a very rapid [single lifetime] drop in temperature. The problem with that will be a very rapid increase in snow cover which will NOT be fun in snow-bound cities. If you think sea level rise is a problem, wait until you see what snow level rise does - once it reaches rooftop level, it becomes really annoying. And that can happen in a couple of years once last years snow doesn't melt. Look how thick it is on Greenland. Scary! That'll be the depth over Hamburg and Chicago.

Unfortunately, while we will be able to hold the line for a century or two, we are fighting a losing battle and the CO2 we release to keep us warm will be stripped from the atmosphere and dumped again on the ocean floor. It won't be economic to keep producing more CO2 as deposits become more difficult to recover and other energy sources become competitive. Heck, the human population will be so low then that even if they all use as much as Americans, they'll be losing ground.

But a century or two will give people time to move to warmer climates and new cities, safely above inbound space mountain tsunamis. There's lots of room in equatorial regions. Africans would be happy to sell some land or ice-age refugees could simply take it over by right of conquest - which is still how they do things in many countries. Libya for example is a prime candidate for Colinisation or Condominium. Iraq too. Saudi Arabia. Zimbabwe.

As you say, those graphs are a teeny bit scary. I didn't realize just how close to the next ice-age we are. But maybe we'll hold it off for a century. Fingers crossed! Buy an SUV. Go for a drive! Heat your house, or cool it in summer. Do your bit to save the world.

That is scary Win.

But all that shows me is that there were equally rapid rises in CO2 ppm concentrations roughly 150k, 250k, 350k, and 400k years ago. There weren't any SUV's around then.

Natural cycles, Win. Let's all chill out and enjoy the balmy weather, man!
