Ice cores recovered from Greenland in the 1970s show that Europe's climate varied hugely during the last ice age, especially in the period between 70,000 and 20,000 years ago. Cold glacial periods were punctuated by warmer times, and the average temperature could rise and fall several degrees within a decade or so.

The earliest modern humans, the Aurignacian people, who appeared around 40,000 years ago, could not cope with the glacial cold either. They retreated south until 25,000 years ago when they were reduced to a few refuges, such as southwest France and the shores of the Black Sea.

The Gravettians appeared in eastern Europe 29,000 to 30,000 years ago complete with flash new tools, such as javelin-like throwing spears and fishing nets, which allowed them to catch a greater range of prey.

They also had clothing to keep the cold out, such as sewn furs and woven textiles, and possibly more specialised social structures. Their ability to tough out the colder climes dominating Europe 18,000 to 25,000 years ago revitalised the human population.

The Neanderthals, however, without either new blood or new technology, found it impossible to survive and died out, probably around 28,000 years ago.

Or the newly arriving humans called the Gravettians had SUV's as a part of their technology thus stopping the Ice Age in its tracks and warming up the world.

I use the word "recovery" with some reservation -- it sort of implies a "normal" and I don't think you can really define "normal" for a global roller coaster observed over geologic time periods.

You're exactly right, although I think a lefty would define "normal weather" as the average temperature while Bill Clinton was in office. "Global Warming" started in January of 2001.
