There will be another ice age w/i the next 1000 yrs whether we like it or not, and regardless of our use of CO2. And yes, it will be the end of civilization as we know it, assuming BHO doesn’t get there first.
I can't find the thread right now, but a recent one said the next ice age is about 2500 years overdue.
I am not confident we will get through this summer. Unless there is a mega GOP wipeout and he is impeached and removed - then we have a lot more to worry about than ice ages.
From a long term geological perspective the planet Earth has spent more time as an ice cube than being warm. The sun is the the only factor that matters. No sunspots, no strong solar wind, increased space radiation, leads to a cooler earth (see The Chilling Stars book).
Global warming is actually a good thing. Imagine modern societies dealing with a modern ice age. Everyone one would migrate to the equator, what a mess.
What everyone overlooks about a new ice age, is that as water is locked up in ice at higher latitudes, more land around the continents, sometimes all the way out to the continental shelves, becomes available. It was certainly that way the last go’round.
Lots of areas presently underwater in the Gulf of Mexico were actually above sea level. Same thing off the west coast of North America.
