Seek ratification of the Kyoto Protocol on Climate Change. Reduce US greenhouse gas emissions to 7% below 1990 levels.

We face a global crisis and we must take action. October 2012 was the 333rd consecutive month that global temperatures were above the 20th century average. The atmospheric concentration of CO2 has risen by 31% since 1750, when the industrial revolution began. It is now at the highest level in 420,000 years. Accelerating arctic warming has led scientists to conclude that unless we rapidly return to below 350 ppm CO2 this century, we risk reaching tipping points and irreversible impacts such as melting the Greenland ice sheet. Island countries could be submerged and coastal cities flooded. We can develop wind and solar energy, and efficient buildings and transportation to reduce our emissions. Europe and Great Britain have made real commitments to CO2 reduction and the US should join them.
