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.

Rick Potts of the Smithsonian Institution discusses the role of climate variation in the evolution of our ancestors.

Three days of heavy rains devastated Louisiana in mid-August 2016. NOAA models find that warming due to greenhouse gases has made an event like that at least 40% more likely and 10% more intense.

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.

James Roger Fleming presents a historical perspective on how our understanding of Earth's climate system developed through innovations and discoveries by pioneering scientists in the 1800s and 1900s who asked and answered fundamental questions about the causes and effects of global climate change.

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.

This 10 minute video builds connections between topics that are important in climate science such as: the impact of variations in Earth's orbit and wobble on it's axis on climate; how the cores being sampled fit into the bigger climate picture; connecting greenhouse gases to melting ice and sea level changes; the sensitivity of the ice melt / sea level rise relationship; and computer model simulations showing connections between ice sheets and sea level.

Was El Niño to blame for the above-average temperatures during November and December 2015?  As always, the answer is not that simple.
