Changing the worlds energy systems

Global warming is happening, and one of the culprits is likely increased emission levels of carbon dioxide and other greenhouse gases as a result of our energy usage. Lynn Orr is director of the Global Climate and Energy Project and one of the worlds leading experts on global warming and CO2 emissions. He says we need to take urgent action now to reduce the risk of a global catastrophe, by increasing energy efficiency, investing in energy resources such as wind and solar with low emissions, and researching potential carbon dioxide sequestration processes.

This talk was part of the End of Oil debate, at Stanford University in March 2006.
