Since we last covered the California drought, conditions in the state have stayed, well, dry—very dry. Statewide, total precipitation is about equal to or below the lowest three-year period since 1895.
Ocean waves slowly eat away coastal cliffs the world over, but in parts of Alaska, these processes have accelerated due to changing climate. These photos document a cliff collapse near Drew Point in the late 2000s.
If mid-century projections of sea level rise prove true for New York City, four times as many people may be living in the 100-year floodplain than were previously estimated based only on observed changes.
In October 2003, a little-known think tank in the Department of Defense quietly released a report warning that climate change could happen so suddenly it could pose a major threat to our country's national security. Why was the Pentagon worried about abrupt climate change? Because new evidence from Greenland showed it had happened before.
Working with private companies, the U.S. Department of Agriculture’s Risk Management Agency uses precipitation data from NOAA’s Climate Prediction Center as part of an insurance program for ranchers and those who grow hay or other livestock forage. This video describes how it works.
Maps of precipitation deficits through January show California mountain areas generally have greater deficits than lower elevations, and Southern California with larger deficits than areas to the north. The drought outlook for February remained grim.
As climate changes in the Great Lakes region, the popular yellow perch–which some consider the ultimate pan-fried fish–may become much less common, potentially forcing consumers to adopt new traditions.
Models project that extreme dust events combined with global warming could advance the spring thaw in the mountains of the Upper Colorado River Basin by as many as 6 weeks by 2050. The earlier disappearance of snow could amplify water disputes, extend the fire season, and stress aquatic ecosystems.
