During early summer 2020, the western North Pacific remained in an almost quiet state, and the tropical cyclone frequency sank to the lowest level on record since 1979. A new research paper provides a possible explanation for the puzzling situation.

In December 2020, the National Integrated Drought Information System held a virtual workshop on flash droughts. The report from that workshop is now available online.

Home to 13 of the 20 largest metropolitan areas in the United States, our nation’s coasts face hurricanes, sea level rise, coastal erosion, natural resource depletion and more. A new white paper lists ways to better understand these complex, vulnerable ecosystems.
