An Inconvenient Truth About Global Warming
Posted by TP on Friday, October 12, 2007
Conventional thinking on recent ice ages – based on as they say “fossil evidence” – says that continent size ice sheets advance and retreat on 40,000- and 100,000-year time scales. Imagine, just some 18,000 years ago (a nanosecond in geological time) an ice sheet over a mile thick covered Manhattan Island. To visualize that, imagine that four Empire State Buildings stacked one on top of the other would still be covered in ice. So much water was held in ice at that time that it is estimated that global sea levels dropped by over 350 feet! To visualize that, stand on any beach on a clear day look out towards the sea as far as the horizon – that’s about 28 miles. You would need to see an additional 40 miles out to see the ocean!
That last glacial period ended about ten thousand years ago. World temperatures then increased so much that by 6000 years ago, lions roamed as far north as Northern Europe and parts of Wisconsin and Minnesota resembled the dry hot savanna of today’s east Africa. Now that’s global warming!
As far as I know, loins today make their home in Africa not Europe, and Wisconsin is home to the holy Mecca of the National Football League, also know as “the frozen tundra of Lambeau Field”. Since the worse ecological damage humans could do 10,000 years ago, say start a forest fire, could not heat the planet, the real inconvenient truth about climate change is that it will happen regardless of what anyone (or everyone) does. Climate change is as inevitable as old age. A wise man plans for the coming of his old age, rather than believing he can avoid it by buying the latest cure-all from some pan-handling preacher.
