ICE Satellite Maps Profound Polar Thinning

xp65 writes "Researchers have used NASA's Ice, Cloud and Land Elevation Satellite to compose the most comprehensive picture of changing glaciers along the coast of the Greenland and Antarctic ice sheets. The new elevation maps show that all latitudes of the Greenland ice sheet are affected by dynamic thinning — the loss of ice due to accelerated ice flow to the ocean. The maps also show surprising, extensive thinning in Antarctica, affecting the ice sheet far inland. The study, led by Hamish Pritchard of the British Antarctic Survey in Cambridge, England, was published September 24 in Nature."

Re:What is the net effect?

Make no mistake; the current skyrocketing CO2 concentration is due to human emissions.

Actually, I think you are drinking too much of the cool aid.

There are many processes contributing to the Co2 increases that aren't attributed to Humans. Volcanic activity under the sea is responsible for a part of it. The sun is responsible for a part also. You see, the oceans are giant carbon sinks and they hold more Co2 when they are colder. The undersea volcanic activity as well as the increased surface temperatures trigger a release of Co2. There are other natural processes involved that caused the increases of Co2 too. While most of the Co2 is caused by human activity, not all of it is nor will it ever be.
