Impacts

Three new analyses on climate extremes together explain how extremes may change in the future, what’s driving them, their impacts on people and ecosystems, and how we can adapt. The most extensive report is from the Intergovernmental Panel on Climate Change (IPCC) and it details the current state of knowledge on climate extremes.

The Sonoran Desert may look very different under hotter and drier conditions in the future, reports a recent study in Global Change Biology.

A draft report by the Southwest Climate Alliance provides information into the state of climate change knowledge in the Southwest region—Arizona, California, Colorado, Nevada, New Mexico, and Utah—and discusses the links between climate in the region and other sectors such as energy and transportation.

New research published in Ecology Letters shows that a single climate parameter, the timing of spring snowmelt, has many different effects on the population growth of the Mormon Fritillar

What had previously been thought—that mountain pine beetles are able to fit two reproductive cycles into a single season due to warming temperatures—has finally been documented by the authors of a new study set to be published in The American Naturalist in May.

Over 3 million people in the U.S. could face the threat of sea level rise within the next century, according to a new study in Environmental Research Letters.

Authors of a new study classified 128 species of birds in California out of 358 evaluated as vulnerable to climate change. Wetland species were found to be the most vulnerable to climate change relative to species that live in other habitats.

Tornado season began early this year, and in one day, more tornadoes than are usually seen for the entire month of March ripped across the Midwest and southeastern U.S.

Winter precipitation in the Southwest is likely to decrease by about 7.5 percent in the future, according to a new study led by University of Arizona researchers.
