some scientists think SO…

It may have looked like this in the past and there is a theory about how it could look similarly in the future. Many people are convinced any changes in temperature are a result of global warming, some may disagree that there is any difference and a third camp feels any changes are mostly from external factors.  This video poses some very interesting questions:

Ice, in its varied forms, covers as much as 16% of Earth’s surface, including 33% of land areas at the height of the northern winter. Glaciers, sea ice, permafrost, ice sheets and snow play an important role in Earth’s climate. They reflect energy back to space, shape ocean currents, and spawn weather patterns.

But there are signs that Earth’s great stores of ice are beginning to melt. To find out where Earth might be headed, scientists are drilling down into the ice, and scouring ancient sea beds, for evidence of past climate change. What are they learning about the fate of our planet… a thousand years into the future and even beyond?

Let’s check out some incredible footage in the video on page 2
