Abandoned Study of Australian Ash Trees Challenges Case for Clearcutting
A landmark study of the towering ash trees that grow in the mountains of Victoria, Australia, which was launched in the 1980s, boosted arguments for clearcutting the iconic trees. But when scientists returned to the site years later, they came to a much different conclusion. More about Abandoned Study of Australian Ash Trees Challenges Case for Clearcutting →

A Missing Piece in Climate Models: Nature’s Own Emissions
Rising temperatures are set to drive up emissions from wildfires, fermenting wetlands, and melting permafrost, but these feedback loops are poorly captured in climate models. Scientists are racing to make sense of these emissions to gauge how much warming may lie ahead.
