Combating Climate Change

Defending Climate Science

Defending Climate Science

Good science lies at the heart of understanding how climate change is impacting species and ecosystems, and how best to respond now and into the future. Our experts work with climate change scientists to ensure we have the best and most up-to-date data available to understand the impacts of climate change on wildlife and ecosystems and so we can address climate change effectively.

Understanding climate change impacts, modeling future projections, and crafting responses all require sophisticated science and observations. Much of this critically important work is conducted by federal agencies, and funding for those programs often comes under attack in Congress. Defenders is a leading advocate seeking responsible funding for programs that work to better understand and combat climate change. Our team on Capitol Hill reacts swiftly and powerfully to any legislative attempts to undercut support for this vital work.

Where We Work
Our Southwest team works to protect rare and threatened species like Mexican wolves, jaguars and ocelots.
Sonoran Pronghorn, Florin Chelaru
Fact Sheet
Known as "prairie ghosts" because they are so elusive, the Sonoran pronghorn (Antilocapra americana sonoriensis) is the fastest land mammal in North America. Smaller and lighter in color than other pronghorn subspecies, it is uniquely adapted for survival in harsh arid conditions.
Wolverine, Kalon Baughan
Fact Sheet
Called "skunk bear" by the Blackfeet Indians, the wolverine is the largest terrestrial member of the weasel family. It has a broad head, small eyes and short rounded ears.
