The WestMap climate analysis and mapping toolbox is an interactive, web-based tool that helps users see the climate conditions that underlie droughts, storms, floods, and changes in streamflow.

The most populated state in the country is facing what may be its worst drought in a century of record-keeping. On January 20, the governor of California declared a state of emergency, urging everyone to begin conserving water.

As climate changes in the Great Lakes region, the popular yellow perch–which some consider the ultimate pan-fried fish–may become much less common, potentially forcing consumers to adopt new traditions.

Concentration of carbon dioxide is about 1.4 times what it was before the Industrial Revolution. How much and how fast will Earth warm if carbon dioxide concentrations double the pre-industrial?

Today's global warming is happening at a much faster rate today than it did in the warm periods between ice ages over the last million years.

NOAA is an agency that enriches life through science. From the surface of the sun to the bottom of the ocean, NOAA advances scientific understanding of Earth's environment, climate, and weather.

Business leaders can evolve their business models to stay profitable while improving their energy efficiency, reducing their carbon emissions, and reducing their, and their climate-related risks.

Among the questions triggered by the entrapment of a Russian ship near Antarctica on Christmas Eve were whether the ice conditions were out of the ordinary, and, if so, whether long-term climate change was playing a role.

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 anomalies for January-December.
