NOAA research model brings severe weather into focus 12Jul2018 Read more NOAA’s best severe-weather model just received an upgrade developed by NOAA researchers that will help the National Weather Service provide more accurate hazardous weather and aviation forecasts. Scientists are also using it to advance a wide array of future forecast tools. Read more
Research: coral reefs will be unable to keep pace with sea-level rise 13Jun2018 Read more Many coral reefs will be unable to grow fast enough to keep up with predicted rising sea levels, leaving tropical coastlines and low-lying islands exposed to increasing erosion and flooding risk, new research suggests.

When noise becomes signal 27Jul2018 Read more Last spring, Governor Jerry Brown declared an end to California’s historic drought that caused over $5 billion in damage to agriculture as well as substantial impacts to fisheries, infrastructure, human health, and vegetation. The drought was not only severe, but it also spanned the winters of 2015-16 and 2016-17, which had unusual and unexpected precipitation that affected the drought’s evolution. Read more
