In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. The lighter the black hole, the faster it evaporates.

Tree species diversity protects forests from climate extremes, study finds‎

New research has found that tree species diversity can play a crucial role in protecting forests from the growing threat of extreme climate events. The study analyzed data from 88,116 separate forest plots across the United States to investigate the impact of "compound climate extremes," when events such as drought and extreme heat occur at the same time.

Lakes aren't just storing water—they're changing the carbon cycle‎

New research suggests that the more lake-rich a network of streams is, the more carbon is released into the atmosphere rather than carried downstream.

Ocean indicators NOAA scientists are tracking for El Niño's arrival on the West Coast‎

Has El Niño reached the West Coast? You might think it has. After all, the ocean off Southern and Central California is unusually warm. But that warmth is from a recent marine heat wave that predates the current El Niño. Much of the Pacific Coast is experiencing relatively normal conditions while still awaiting the impacts of what could be a very strong El Niño.
