The 'Clear and Present Danger' of Climate Change

Almost 100% of climate scientists now say global warming is caused by human behavior and that action now is a moral imperative for future generations.

It's difficult to predict specifically what's next to come, but a draft report to the UN says government foot-dragging will lead to devastating surprises. We hear about new pressures on the Obama Administration and how politics are complicating the findings of science.
