"The world is approaching a watershed moment in its battle to limit the risks posed by global climate change, and international leadership from the United States is needed now more than ever before.

"A report by the Intergovernmental Panel on Climate Change in September warned that emissions of carbon dioxide and other greenhouse gases are already raising temperatures, melting glaciers and the polar ice caps, elevating sea levels and changing the strength and frequency of many extreme weather events.

"Without sharp reductions in emissions, global average temperature could be much more than 2C degrees above its pre-industrial level by the end of the century, beyond anything the Earth has seen for millions of years, and way outside the experience of modern Homo sapiens."
