Make a Donation Cooler Smarter: Practical Steps for Low-Carbon Living

To counter recent attacks on climate science, UCS has launched a major initiative to refocus America's attention on the real impacts of climate change and the urgent need to rein in global warming pollution. But we need your support to make this work possible.

Your donation today will allow us to be an independent voice for change and to continue developing science-based solutions to important environmental, public health, and security issues.

Join UCS with a membership gift of $35 or more and receive a FREE copy of our new book, Cooler Smarter: Practical Steps for Low-Carbon Living.
