People are starting almost all the wildfires that threaten U.S. homes, according to an innovative new analysis combining housing and wildfire data.

Volcanic ash shuts down air traffic and can sicken people. But a new study suggests it may also be more important for Earth's climate than once thought.

Three �Ͼ�Ʒ�� faculty are principal investigators on a new five-year, $6.9 million National Science Foundation grant to study the “critical zone”—from Earth bedrock to tree canopy top—in the American West.

A new study of 22 burn areas across 710 square miles found that forests are not recovering from fires as well as they used to, and many regions will be unsuitable for ponderosa pine and Douglas fir in the coming decades.

Viewers from Baltimore to Berlin can now step out onto an ice floe in the middle of the Arctic Ocean and watch and listen as scientists race the fading light to set up one of the most ambitious international climate collaborations ever, MOSAiC.

New research identifies fertilizer and pesticide applications to croplands as the largest source of sulfur in the environment—up to 10 times higher than the peak sulfur load seen in the second half of the 20th century, during the days of acid rain.

Attention to climate change has rapidly declined in recent months. That's concerning, say study authors who found that simply directing one's attention to an environmental risk—even briefly and involuntarily—makes people more concerned and willing to take action.

Alaska is getting wetter. A new study spells out what that means for the permafrost that underlies about 85 percent of the state, and the consequences for Earth global climate.
