The U.S. Scientists and Economists' Call for Swift and Deep Cuts in Greenhouse Gas Emissions is a call to our nation's leaders to require immediate, deep reductions in heat-trapping emissions that cause global warming. The statement is endorsed by more than 1,700 scientists and economists with expertise relevant to our understanding of the scientific and economic dimensions of climate change, its impacts, and solutions. This marks the first time leading U.S. scientists and economists have joined together to make such an appeal.
This unprecedented list of signatories includes six Nobel Prize winners in science or economics, 30 members of the National Academy of Sciences, 10 members of the National Academy of Engineering, 10 recipients of the MacArthur Fellowship, and more than 100 members of the Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Peace Prize.
The letter, with the full complement of signatures, will be delivered to every member of Congress in spring 2008, as both chambers prepare for critical votes on national climate policy. In addition, several scientists and economists will personally delivered the letter and meet with their senators and staff to discuss the importance of taking action to reduce emissions while growing our economy.

Quotes From Scientist and Economist Endorsers
"Recent events have demonstrated the worldís
vulnerability to climate-related natural disasters. Further delaying action on climate change may make these events even more catastrophic in the future."

of Sciences; Member, National Academy of Engineering
"The United States worked with other nations to take on the ozone threat; so, too, must we lead the international effort to reduce heat-trapping emissions that cause climate change."

"Economists now join climate scientists in a unified call for action to address the causes of climate change. Failure to act now is the most risky and most expensive thing we could do."

"Physicists tend to be supercritical of strong conclusions, but the data on global warming now indicate the conclusions are not nearly strong enough."

"The new energy economy is upon us, and the states are already playing a key role in the research, development, and deployment process that will simultaneously stimulate growth and achieve our climate goals."

"Evidence is mounting from many different scientific disciplines that Earthís natural systems are already undergoing rapid change. We need to act now to reduce heat-trapping gas emissions, for the sake of our children and the other species with whom
we share this planet."

"I think the world has never faced a problem like global warming and the enormous environmental destruction it can cause. The impacts will be felt most severely by poor people around the world, which in turn will have serious repercussions for all of us."

"The message from California to federal policy makers is encouragingówe know that a combination of political will and smart policies that promote energy conservation and technological innovation can cost-effectively reduce global warming emissions."
- Michael Hanemann

"Adaptation for both human and natural ecosystems will likely be more difficult and costly for a faster rate of warming than for slower rates. Delaying action is an extremely risky path to continue on."

"The future of our society depends on effectively managing and reducing greenhouse gas emissions. Public and private research and development support for these efforts will allow us to transition to a carbon-neutral energy system that improves both environmental quality and economic growth."

"Preventing dangerous climate change is a great investment. It will cost between one and two percent of GDP, and the benefits will be between 10 and 20 percent. Thatís a return of 10 to 1óattractive even to a venture capitalist."

"The consequences of global climate change constitute one of the most serious threats facing humanity. While the poor and the impoverished will suffer the most, the potential for catastrophic climate change that can adversely affect the habitability of the
entire planet is quite real."

"Investing now in energy efficiency and low-carbon technologies not only will create new business opportunities, but is also likely to be less expensive than a crash program to implement these solutions at a future date, when it will be more difficult to limit climate impacts."
