IPCC Report: Global Warming "Very Likely" Our Fault

For those who are still trying to determine responsibility for global warming, this new U.N. report on climate change is a scientific smoking gun. We ignore it at the peril of our children and their children.

The debate about climate change has rapidly moved from 'if' to 'when.' The world's scientific community is stating with one clear voice that human activities are causing climate change and we can no longer afford to move at a glacial pace in stopping, stabilizing, and reducing the greenhouse gas emissions that we know are causing global warming. It falls to this Congress to meet this challenge by moving aggressively to transition away from forms of energy which have the capacity to destroy the planet as we know it.
