Union of Concerned Scientists

Make a year-end gift to defend science and scientists.

Science—and scientists themselves—face attacks from politicians, media pundits, and corporate-funded "think tanks." These ideologues misinform the public and undermine science.

UCS supporters know that our best hope for a healthier environment and a safer world can be found in science. Your donation helps put science into the discussions on climate change, clean energy, our food system, and more.

Defend science and stand up for the facts. Donate today to help reach our $400,000 goal by December 31.
