I keep hearing all that tripe about human caused global warming. If the planet is heating up, how is it possible to have, at the same time, record cold temperature all up and down the East Coast.
That being said, it is also true that the earths temperature has been increasing since the last ice age, 12,000 years ago. With man or without man the earth's climate changes, sometimes dramatically, and rapidly. 8,000 yrs ago the entire north of Africa was a lush, verdant, land filled with rivers and lakes. There were all manner of tropical flora and fruit bearing trees. Today we can easily locate the bones of water loving creatures, (radio-carbon dated to 8,000 yrs old) all across Northern Africa. In what is now The Sahara Desert, crocodiles, hippos, elephant, huge constrictor snakes, egrets, flamingos, and early man lived in what could rightly be called a "Garden of Eden".
It has been speculated by scientists that minute shifts in the earths axis of rotation, is the likely cause.
