Tonight I watched a 2-hour program on The History Channel called 'Titanoboa'. In an open pit coal mine in Columbia, scientists recently found fossilized remains of a fearsome, gigantic boa-type of snake that was about 48' long with an estimated weight of 2500 lbs. Also found there were the remains of huge crocs, turtles & plants from 60 million years ago that all dwarf anything today.

Their hypothesis is that the only way that these creatures & plants could have grown that large is due to a far warmer climate at that time than we have presently - probably at least an average of 5 degrees C warmer globally than now. Interestingly, there were no smokestacks back then.

In the past our climate has been both much warmer & far colder than now. Despite humankind's activities on this rock, our climate will continue to fluctuate naturally over the eons until the eventual demise of our sun...
