New Mexico’s FoodShed Alliance

FoodPrint NM in New Mexico is working to shrink the distance between the farm and the fork and curb climate change in the process.

Land Use Planning in the Changing Climate of the West

An assessment of western state climate plans finds many communities could cost-efficiently reduce their emissions by about 20 percent if their land use planning-related policies were fully implemented.

Monsoon Modeling

Atmospheric scientists explain the complexities associated with trying to predict the North American Monsoon with a global climate model.

Welcome to the Southwest Climate Change Network

This website is a virtual community for scientists, other experts, decision makers, and the public to share information on climate change and collaborate on solutions.

Temperature Changes

The Southwest is projected to warm faster than the world as a whole in coming decades, with summer temperatures rising even faster than winter ones. Average annual temperatures in many parts of the region could be 5 to 8 degrees F higher than they were even during the hot quarter century that began in the 1970s.

Precipitation Changes

Temperature rise alone increases the risk of regional drought, with its effect on evaporation rates and extreme events. On top of that, precipitation is projected to decline in the region—even as the risk of heavy rainfall events increases.

Streamflow: Natural Variability and Human-Caused Changes

Current observations suggest that climate change is altering streamflows in ways that negatively impact water supply for southwestern populations. Many climate models suggest that these changes will worsen as the climate warms, accentuating the natural variability inherent in river flows.

Greenhouse Effect

The greenhouse gas effect functions by trapping in the atmosphere heat from the Sun’s radiation. The greenhouse gases can be thought of as creating a one-way mirror—they allow the short wavelength energy emitted by the Sun to pass through the atmosphere and warm the Earth’s surface, but they do not allow all the longer wavelength energy radiated by the Earth back to space.
