Human-caused climate change is not the sole cause of any single extreme event. However, changes in the intensity or frequency of extremes may be influenced by human-caused climate change.
A Q & A about the science of detecting the influence of global warming on hurricanes, fires, and other extreme events.
Rick Potts of the Smithsonian Institution discusses the role of climate variation in the evolution of our ancestors.
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.
Sochi will be among the warmest cities to have hosted a Winter Olympic Games. Climate change could make many previous Olympic cities unsuitable for Winter Games by the end of the century.
Climate Science 101: Historical Perspectives on Climate Change
February 15, 2012
NOAA researchers have built a "time machine" for weather that provides detailed snapshots of the global atmosphere from 1891 to 2008. The system's ability to "hindcast" past weather events is emerging as a powerful new tool for detecting and quantifying climate change.
Out of the 29 Northern Hemisphere summers that led up to a winter El Niño, how many were hot versus cold? Wet versus dry? These maps are a global climate scorecard for the influence of El Niño on June-August climate.
Was El Niño to blame for the above-average temperatures during November and December 2015? As always, the answer is not that simple.
