What!?? You say Global Warming may not be caused by HUMANS???

I jest, of course.  The earth was warming and cooling a very long time before we came on the scene.  Why ANYONE would think we could change the course of nature is beyond me.  I see that as dipping out the ocean one spoon at a time.  I do agree we should take care of those things we can, no pollution, husband our resources and things like that, but change the course of the earth, no, we can't. Not possible we are not that good.

Ice-covered volcanoes may answer climate change questions
Eruptions from mountains such as Iceland's Eyjafjallajokull create rocks that offer scientists clues about global warming.
By Karen Kaplan
Ice-covered volcanoes like the one in Iceland that brought European air traffic to a standstill are the center of an emerging branch of volcano science that seeks to answer important questions about climate change.

Scientists believe the rocks created when volcanoes erupt beneath glaciers contain distinct chemical signatures that indicate the thickness of the ice that was above the volcanoes when they blew. By correlating the thickness with the age of the rocks, researchers can estimate the degree to which Earth was covered by glaciers thousands — or even millions — of years ago. That information is crucial to climatologists who want to understand how ice and temperature conspire to make the globe cool down or heat up. Read the rest.
