Unfortunately, powerful oil and coal companies, agribusiness, arms control opponents, and groups like the U.S. Chamber of Commerce are twisting scientific facts to incite fear and sway elected officials into opposing efforts to curb global warming, reduce the threat of nuclear weapons, and keep our food safe.

We can't allow these groups to derail essential action. ...
UCS is taking the lead to expose and challenge the misuse of science. Recently, when opponents of climate action misrepresented illegally obtained emails from scientists in Great Britain to try to manufacture doubt on the eve of an important climate summit in Copenhagen, UCS quickly and skillfully mobilized scientists to set the record straight with the media and the public. The science is clear. There is no doubt. Swift action to curb emissions is needed now.

Debunk the myth that nuclear weapons improve our national security.
Pressure Congress to lock-in protections that will keep science transparent, independent, and in service of public health and the environment.
Educate and mobilize scientists, economists, and citizens to advocate for practical solutions to problems impacting our health, environment, and security.
UCS is the only science-based organization that partners leading scientists with concerned citizens to advance science-based solutions to curb global warming, reduce the threat of nuclear weapons, generate clean and renewable energy, produce more fuel-efficient cars, and much more.

In contrast to the paid-for “experts” hired by special interests to mislead the public, UCS’s scientific authorities include Nobel laureates, physicists, biologists, economists, and respected professors who are dedicated to finding the truth. And unafraid to speak that truth to power.
