CarbonTracker is a tool for modelling sources and sinks of carbon dioxide. Users can download the code, carbon dioxide data, and the tool's carbon flux estimates to conduct their own analyses or to help improve the system.
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.
ANIMATION: The globally averaged temperature for 2013 tied as the fourth warmest year since record keeping began in 1880, according to NOAA scientists. It was the 37th consecutive year with a global temperature above the 20th-century average. This animation starts with the 2013 difference from average temperature and continues through monthly temperature anomaliies for January-December.
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.
