The Union of Concerned Scientists is the leading science-based nonprofit working for a healthy environment and a safer world. UCS combines independent scientific research and citizen action to develop innovative, practical solutions and to secure responsible changes in government policy, corporate practices, and consumer choices.

What began as a collaboration between students and faculty members at the Massachusetts Institute of Technology in 1969 is now an alliance of more than 250,000 citizens and scientists. UCS members are people from all walks of life: parents and businesspeople, biologists and physicists, teachers and students. Our achievements over the decades show that thoughtful action based on the best available science can help safeguard our future and the future of our planet.

Bringing science to the candidates

The next president will lead a nation that is facing critical and complex challenges. As presidential candidates hit the campaign trail, we need to demand that candidates from both parties stand up for science and put forward proactive, evidence-based plans to address the most serious issues facing Americans today, including climate change, nuclear arms, food security, and energy and vehicle development. That’s why we’re calling on the presidential candidates for president to debate the big science & technology issues of our day—add your voice today!

Help communities prepare for climate change

One thing communities on the frontlines of climate change badly need: support from federal agencies for measures to increase their resilience before the floods, storms and other climate impacts strike. Urge the directors of the Federal Emergency Management Agency and the U.S. Department of Housing and Urban Development to support policies that will help these communities be better protected and prepared for those climate changes we can’t avoid.

Petitioning Chairman Smith

Defend climate scientists from bullying

Make no mistake—this isn’t about accessing more data or better understanding the research. NOAA’s data and methodology have been publicly available for months, and NOAA scientists met multiple times with committee staff to answer questions about the research. This subpoena for emails and other confidential information is about Chairman Smith abusing his congressional power to cast doubt on the science and smear the scientists for publishing results that don’t align with his climate denial. The harassment by the House Science Committee isn’t just a problem for NOAA scientists—it’s a problem for all scientists and the public. Scientists and researchers need to be able to spend their time doing the scientific work we heavily rely on, whether that's making sure our air is safe to breathe, predicting the path of hurricanes, or researching new drugs to fight disease. But when scientists are afraid of political interference or being unfairly targeted for their work, they can't do their jobs—and we all lose out. Stand up for science and call on Chairman Smith to stop bullying climate scientists.
