It also means the earth has been a whole lot warmer in the past than it is now. So are we "confronted with global warming" or just going through a natural planetary cycle? And, BTW, duh; it was called Greenland because it was green.
Right - and it wasn't called that 450,000 years ago. It was named Greenland by Scandinavian explorers during the Medieval Warm Period. It was nice and green around 1,000 years ago and therefore obviously warmer that it is today. That was a long time before the Industrial Revolution if I got my history right.
Any scientist who has bothered to check knows that it has been a lot warmer. The steady state climate advocates are idiots there is really no other way to describe them.
