U.S. Scientists and Economists' Call for Swift and Deep Cuts in Greenhouse Gas Emissions
It concludes:
A strong U.S. commitment to reduce emissions is essential to drive international climate progress. Voluntary initiatives to date have proven insufficient. We urge U.S. policy makers to put our nation onto a path today to reduce emissions on the order of 80 percent below 2000 levels by 2050. The first step on this path should be reductions on the order of 15-20 percent below 2000 levels by 2020, which is achievable and consistent with sound economic policy.
There is no time to waste. The most risky thing we can do is nothing.
