(Video) The Climate Prediction Center's outlook for December through February gives California a 2-in-3 chance of receiving normal precipitation or better. Cool, wet conditions are favored in some southern regions, while warm weather is favored to the west, including Alaska and Hawaii.
In the Northeast, the amount of rain that came down in very heavy events increased by more than 70 percent between 1958 and 2010. A new law in New York requires state agencies to start thinking ahead about increases in extreme rain and other climate change risks.
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.
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.
Many areas of the world experienced higher-than-average monthly temperatures according to the latest statistics from NOAA’s National Climatic Data Center. The average global temperature for May 2013 tied with 1998 and 2005 as the third warmest May since record keeping began in 1880.
NOAA’s Climate Prediction Center (CPC) has issued its 2013 Atlantic hurricane seasonal outlook. In this video, Gerry Bell, a NOAA CPC meteorologist, explains that as of May 23, 2013, the outlook favors an above-normal Atlantic hurricane season from June 1 through November 30.
The Spring Outlook encompasses temperature, precipitation, drought, and flooding expectations for the coming three months, and Mike Halpert, Acting Director of the Climate Prediction Center, discusses the outlook and its implications.
We can’t immediately link Hurricane Sandy itself to climate change, says climate scientist Cynthia Rosenzweig, but the flooding damage we can. Partly due to global warming, sea level has climbed about a foot in the NYC area over the past century, giving storm surges a “step up” along the coast.
