California Faces Heightened Risk of Megafloods
Although California is currently contending with historic drought, a new study indicates that climate change is sharply increasing the risk of a catastrophic megaflood that could submerge large swaths of the state and displace millions of residents. The study by scientists at the National Center for Atmospheric Research (NCAR) finds that the likelihood of such […]

Water Resources to Become Less Predictable with Climate Change
Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere by later this century, according to a comprehensive new climate change study led by the National Center for Atmospheric Research (NCAR). The research team found that, even in regions that keep receiving about the same […]

Record-breaking ocean heat fueled Hurricane Harvey
BOULDER, Colo. May 11, 2018 — In the weeks before Hurricane Harvey tore across the Gulf of Mexico and plowed into the Texas coast in August 2017, the Gulf’s waters were warmer than any time on record, according to a new analysis led by the National Center for Atmospheric Research (NCAR). These hotter-than-normal conditions supercharged […]

North American storm clusters could produce 80 percent more rain
BOULDER, Colo. November 20, 2017 – Major clusters of summertime thunderstorms in North America will grow larger, more intense, and more frequent later this century in a changing climate, unleashing far more rain and posing a greater threat of flooding across wide areas, new research concludes. The study, by scientists at the National Center for […]

Scientists link recent California droughts and floods to distinctive atmospheric waves
BOULDER, Colo. April 7, 2017 – The crippling wintertime droughts that struck California from 2013 to 2015, as well as this year’s unusually wet California winter, appear to be associated with the same phenomenon: a distinctive wave pattern that emerges in the upper atmosphere and circles the globe. Scientists at the National Center for Atmospheric Research (NCAR) […]

Climate change already accelerating sea level rise, study finds
BOULDER, Colo. Aug. 10, 2016 — Greenhouse gases are already having an accelerating effect on sea level rise, but the impact has so far been masked by the cataclysmic 1991 eruption of Mount Pinatubo in the Philippines, according to a new study led by the National Center for Atmospheric Research (NCAR). Satellite observations, which began […]
