The decline in total occupied forest may not equate to an overall loss in butterfly numbers, but scientists are still concerned that their populations are suffering.

Agency documents, including scientific analyses, included language that misrepresents the uncertainty surrounding climate change, according to a New York Times investigation.

Take a tour of a forest killed by salt inundation brought by rising seas—a powerful reminder that climate change is affecting ecosystems around the world.

Dendrochronologist Valerie Trouet explains what researchers can learn about the climate of the past by looking at tree rings.

Watch Profilee Joanne Chory deliver a TED talk on her project to breed climate change–busting plants.
