Change is not a bad thing. All these doom sayers going on about global warming going to end life on earth is getting ridiculous. Nature always achieves a balance. Any warming trend is only going to be temporary, as has already been pointed out. Any stress on animal populations will only be temporary. Human are adaptable and can live in just about every environment that exists on this planet, global warming does not threaten to remove any of those envirionments, just shift them around some. Not to mention the earth has been warming for 10,000 years( with occasional cooling fluctuations), yet humans and animals are still here. The doomsayers will always be a part of life. It's a fact that throughout human history, there's always been someone or someones predicting the end of the world, grasping at whatever straws are in their reach as proof of impending doom. Yet, the doom never comes. Nothing new here, move along.
Edit: anybody notice that ice shelf breaking up had no impact on sea level. Ice that already displaces water does not displace more floating freely than floating, but not floating freely.
