Add a new item to the list of things that have migrated in response to climate change: the latitude where hurricanes reach their maximum intensity. The shift was accompanied by increasing vertical wind shear near the equator.
Since 2004, researchers in NOAA’s Global Monitoring Division have released the Annual Greenhouse Gas Index: a single value that compares the total warming effect of each year's concentrations of heat-trapping gases to 1990 levels.
In April 2011, Texas was in the midst of what may have been its worst fire season in history. As the season began, NOAA outlooks and observations helped fire managers think strategically about where their resources could be most effective.
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.
