During the Last Glacial Period, which ended approximately 12,000 years ago, climate change existed as a powerful phenomenon, much as it does now, albeit for different reasons.   Over the course of the ice age, a series of abrupt warming episodes punctuated the coldness, each of them sending temperatures soaring (by up to 16 degrees Celsius) in temporary heat waves that flared for decades before disappearing. ...

These paleo-tempests, which are seldom matched in our modern climate frequently covered Western Europe in some of the thickest layers of ice-age dust found anywhere previously on Earth. This is demonstrated by a series of new estimates of the sedimentation and accumulation rates of European loess layers obtained by Senior Research Scientist Denis-Didier Rousseau from Ecole Normale Supérieure in Paris, France, and colle...
