Two centuries ago, our knowledge of the past barely reached back past classical Greece and Rome: say, 3,000 years. Now scientists are working hard to puzzle out past climate states ranging from hundreds to billions of years ago because understanding the patterns of the past may help us through whatever happens next. Every scrap of information may be valuable, writes Gwynne Dyer.
L'Anse aux Meadows, in Newfoundland, is an archaeological site, first excavated in the 1960s, of a Norse settlement dating to 1,000 years ago. Palaeohistorians at Groningen University solved the exact date of the first European settlement in the New World:1021 AD.
you have got to be messing with us. WHY WOULD YOU NOT CONSIDER THE FREAKING PAST when coming up with models?!?!?!? OH cause it is past the point you can lie to us and the cooling of earth blew out Muh Global Warming.. Scientists have been jesters of the court.
