A new NOAA-led report shows that Arctic air temperatures continue to rise at more than twice the rate of global air temperatures, a phenomenon known as Arctic amplification. Increasing air and sea...


Cal-Adapt is a web-based climate adaptation planning tool developed in part by the University of California, Berkeley's Geospatial Innovation Facility for the State of California. Cal-Adapt allows users to identify potential climate change risks in specific geographic areas throughout the state. Users can either query by location, or click on an interactive map to explore what climate impacts are projected to occur in their area of interest.

Paleoclimate Reconstructions for the Southwest

The longest instrumental climate records date back only about 100 years in the Southwest, a timeframe that likely does not capture the full range of climate variability. Extending the record to earlier times provides additional information on the length and severity of past droughts.  This tool created by the Climate Assessment for the Southwest allows users to visualize the climate variability during the past 1,000 years or so in each climate division in Arizona and New Mexico.

Southwest Climate Outlook

The Climate Assessment for the Southwest puts out monthly outlooks for the region. These outlooks include a look at last month's temperature and precipitation data, the current state of El Niño/La Niña and reservoir levels, and forecasts for temperature, precipitation, and streamflow. Additional seasonal sections of the outlook include wildland fire and snowpack updates. Archives are also available online.
