The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global yields of corn and wheat because of warming temperatures.

A new study debunks the idea that cyclones have no long-term, lasting economic impacts, and suggests the urgent need for revamping disaster policy around the world.

Global economic losses from cyclones linger for decades, study finds

Scientists analyzing 25-foot piles of ancient shells have found that the El Niños 10,000 years ago were as strong and frequent as the ones we experience today.

July 10, 2014 | More than 1,000 forecasters, researchers, and other professionals from around the globe will convene in Montréal on August 16–21 for a first-of-a-kind meeting aimed at pooling international thought on where weather prediction is headed. NCAR and UCAR participants are on tap to cover a wide range of promising developments.

July 9, 2014 | Warmer temperatures, higher humidity, and less rain are correlated with an earlier start and peak of each year’s Lyme disease season, researchers have found. Using the dates of Lyme disease cases reported to the U.S. Centers for Disease Control and Prevention (CDC) and meteorological data from 1992 to 2007, researchers at NCAR and the CDC have for the first time analyzed the timing of the warm-season ramp-up of Lyme disease transmission.

August 20, 2014 | One of the challenges in forecasting tropical cyclones is that measuring atmospheric conditions over the open ocean is extremely difficult. New research indicates that the COSMIC microsatellite system, which uses a technology known as GPS radio occultation to observe remote regions of the atmosphere, can significantly improve predictions of tropical cyclones.

August 12, 2014 | For millions of people, the onset of El Niño or La Niña in northern autumn indicates whether they’re likely to face unusually warm, cold, wet, or dry conditions over the coming winter. A new modeling study pins down the process that apparently determines why La Niña events often last twice as long as typical El Niño events—a result with major implications for seasonal predictions extending more than a year out.
