The Hidden Perils of Permafrost - Scenic Reflections

There's something buried in the Arctic soil that could have a huge effect on the future of our planet's climate. Scientists from Lawrence Berkeley National Laboratory have descended on Barrow, Alaska to study permafrost -- soil that remains frozen throughout the seasons, often for thousands of years. They're interested in permafrost because it has the potential to release an enormous amount of greenhouse gases in a short amount of time if rising temperatures cause the permafrost to thaw.
