Scientists brave Hurricane Harvey's fierce winds and pelting rain—Irma is next

Sept. 8, 2017

"People just grabbed whatever they could carry and went," said atmospheric scientist Josh Wurman, director of the Center for Severe Weather Research (CSWR) in Boulder, Colorado. Wurman should know. He and scientist Karen Kosiba, also of CSWR, were running the wrong way, heading for ground zero, where Harvey's fury would roar onshore. They weren't alone. A National Science Foundation (NSF) Doppler-on-Wheels (DOW) was with them.

Dinosaur-killing asteroid could have thrust Earth into 2 years of darkness

Aug. 21, 2017

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, according to a news release from the National Center for Atmospheric Research (NCAR). This event would have shut down photosynthesis, drastically cooled the planet and contributed to the mass extinction that marked the end of the age of dinosaurs.
