Measureing How Long Rock Has Been Exposed to Ice

Here is an interesting article about climate change and what it could mean in Antarctica. It nicely explains that the models expect the ice sheet to remain pretty much in balance because of increased snowfall balancing the melting. It also revolves around providing information on a team going down to Antarctica to research how long the rock on a mountain has been exposed to the sun. Who even thought that such a thing could be done? The point of this is to help determine the past thinning of the ice sheet to better understand the current situation and future of the ice sheet. This article is full of more information including an interesting tidbit on that naturally the earth should be in a global cooling period instead of the human forced warming. Not sure about the science behind this statement, but certainly an interesting idea to ponder towards how much humans are impacting the natural cycle.
