My job regularly requires explaining complex science and policy topics to the media, public, and decisionmakers. So I took over the Union of Concerned Scientists’ twitter account (#GretchenTakeover) to share my top tips for talking about science in decisionmaking, examples of effective science communication, and suggestions for how to advocate for the Scientific Integrity Act.  Here are the key takeaways.

That said, it would be more accurate to say, “It’s not only the heat, it’s also the humidity.” Based on a question about water vapor and global warming we recently received from a UCS supporter in Lexington, Kentucky, I talked with the lead author of our recent Killer Heat report, Kristina Dahl, a senior climate scientist in our Climate and Energy Program, about increasing heat and humidity, global warming, and the choices we face.

, Research scientist

Today, the Trump administration released a final rule dismantling the role of science in informing protections for endangered and threatened wildlife.

Today, science will take a backseat as the new rule will sideline scientific evidence and emphasize considerations of economic costs in decisions to list species and/or the habitat they depend on under ESA. This new rule will result in less protection for America’s threatened wildlife and a higher likelihood of losing species forever as Earth’s sixth mass extinction occurs.  Read more >
