Wilkins Ice Shelf disintegrating
Mammoths have been found frozen, preserved, in Siberian and Alaskan
ice. Still had tropical flowers in their guts. They're dated to around 10,000 years ago, IIRC. What was going on up there then? Who or what made the atmosphere so warm that this was possible? Volcanoes? Or were their carcasses carried there by some unknown means, preserved all the while? There are many, many questions surrounding this global warming stuff, with too few answers. All the same, I think our relentless and increasing consumption of oil and gas and coal and everything else we take out of the ground is getting more immoral all the time. Even the manufacture of the "Go Green" T-shirts you can buy at Wal-Mart causes some pollution. We could all do with living a lot more simply, but the downside to that is the loss of millions of jobs in the places that make most of the junk we buy now. Too many have grown up in this sort of arrangement and need things the way they are. It's going to get interesting if we don't do something. And interesting if we do. Dan |
