Alaska’s coastal waters are especially vulnerable to the drop in pH—acidification—that comes when excess carbon dioxide dissolves into the ocean from the atmosphere. These maps show relative risk levels for commerical and subsistence fisheries.
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.
Despite uncertainties around future precipitation change, it is clear that as temperatures rise in Colorado, the state is expected to face significant challenges to managing water resources, according to a new report.
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.
According to the 2009 National Climate Assessment, heavy downpours have increased in frequency and intensity during the last 50 years. Models predict that downpours will become still more more frequent and intense as greenhouse gas emissions and the planet’s temperature continue to rise.
