NOAA OAR played a significant role in the recently-convened AGU Chapman Conference on the California Drought, held in Irvine, California during April 20-22. The conference was convened by Marty ... ...

Charles Keeling's measurements of carbon dioxide from the summit of Mauna Loa have become a landmark for mankind's impact on the Earth. In this video, NOAA scientists talk about the history of the observations that allow us to connect Earth's warming climate to the greenhouse gases from burning fossil fuels.

A weak high, a cut-off low, and rapid ocean warming conspired to dump torrential rains in Chile's Atacama Desert in late March 2015.

ENSO is a complicated thing to model. What are the challenges, and how can we overcome them?

Summary: After a butterfly species disappeared from a location where it had been found for many years, conservation professionals accessed climate projections to identify potential habitat for its recovery.

Strong evidence suggests that mountain areas are warming more quickly than lower elevations—with serious consequences for water supplies. But historical weather observations from mountain ranges are limited, leaving scientists with plenty of questions.
