According to the same scientists,In the begininng the Earth was a molten unihabital mass for billions of years before there was any life of any kind. I think if the earth recovered from that,(it's birth) it can handle anything we throw at it.Should we do what we can to conserve and recycle? Yes it makes good sense, but to continually listen to these green house folks and how the earth is getting warmer presumably from its inhabitants is complete and utter hogwash.A chicken little story created by our government to extort more dollars from our wallets.Maybe it is getting warmer, by a degree or so over thousands of years,If you look at the big picture from the history of the planet it is just another natural process of the planets evolution. Lets not make a mountain out of a mole hill.To think that we are all responsible is just arrogance on our part.Every year volcanos erupt, earth quakes occur, causing destruction,devastation and pollution, far outweighing anything we could possibly create as inhabitants. These are all natural occurrences.What about those hot Mays in the 1880's? They were happening then according to your own information.The planet had less inhabitants then and the industrial revolution hadn't even started.(Isn't that around the year that the volcano Krackatoa erupted?)How could we have been responsible for those Hot Mays on record in the 1800's? Yet they still happened.I am sorry, but all these green folks in my opinion have been fooled by our government and other like minded sheep into believing global warming is something we have created, I don't buy it.!Fact is weather and weather patterns change constantly without any help from us.In it's history the Earth has gone through all sorts of changes and none of them were in direct response to what it's inhabitants were doing, in fact without the changes I doubt we would even exist right now.Change is part of life, ours and the earths.
