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.
Nearly ten percent of U.S. watersheds are living beyond their means when it comes to their water supply. For nearly half the country, water stress is projected to worsen by mid-century because of climate change, according to a recent NOAA-funded analysis.
The most likely explanation for the lack of significant warming at the Earth’s surface in the past decade or so is that natural climate cycles caused shifts in ocean circulation patterns that moved some excess heat into the deep ocean.
Stunned by Sandy's devastation, the city of New York undertook an ambitious project: to update its long-term sustainability plan using the latest climate science. Their goal was to understand how much sea level could rise, how soon, and just how vulnerable the city would be if some of the more extreme climate change projections turn into reality.
In June 2013, many areas of the world experienced higher-than-average monthly temperatures. According to the latest statistics from NOAA’s National Climatic Data Center, the globally averaged temperature for the month tied with 2006 as the fifth warmest June since record keeping began in 1880.
Looking at the temperature maps for March 2013, you might think that Old Man Winter over stayed his welcome or that Mother Nature was trying to make up for last March’s record-breaking heat. Much of the country felt spring would never arrive!
NOAA released the 2012 installment of the annual Arctic Report Card on December 5, 2012, as part of the American Geophysical Union's fall meeting. This image collection is a gallery of highlights based on the report's major themes. It was developed by the NOAA Climate.gov team in cooperation with Arctic Report Card authors and other Arctic experts.
Much of the western and southern central United States could be in for a warmer-than-average winter this year, while the upper Midwest and Florida peninsula could experience colder-than-average temperatures. Most of California and western Nevada could experience well-below-normal precipitation, while parts of the southeast could receive well-above-normal precipitation.
