In 1985 a geological team discovered an ancient fossil forest. The trees were from the Eocene period about 45 million years ago.The large mummified stumps were discovered to be the Dawn Redwood (Metasequioa glyptostroboides) a tree now only found naturally in China.Scientists estimated the climate was sub-tropical somewhat like Florida today. On a nearby island they found the fossilized remains of alligators and rodents. The climate was much warmer 45 million years ago in the Arctic Archipelago and leads me to wonder? Have we caused the climate to change by our actions here on earth, are we in a warming cycle that occurs naturally, and why not call this Climate Change instead of the ominous Global Warming. What do you think about this issue? Is global warming a climate change that occurs naturally in the big picture of our earth's evolution. What do you think?
