Researchers working with Randall Martin at the McKelvey School of Engineering quantified changes in global air pollution from fine particulate matter. They found that global PM2.5 exposure decreased steadily from 2011 to 2019, largely driven by rigorous air quality management in China and slower growth in other regions.

Atmospheric scientists led by Jian Wang, at the McKelvey School of Engineering, analyzed data from an Arctic expedition and found that blowing snow is a source of sea salt aerosols, impacting Arctic climate models.

Washington University’s new Center for the Environment begins its work, another step forward in the “Here and Next” strategic plan.

Volcanic eruptions can cause the Pacific Walker Circulation to temporarily weaken, inducing El Niño-like conditions. Human activity is affecting this system, too.

Research from Rajan Chakrabarty and Rohan Mishra at the McKelvey School of Engineering reveals an unexpected impact of wildfires on climate change.

For decades, Forest Park has enticed generations of WashU community members to step outside the university’s campuses and explore. Today, students and faculty are venturing deeper into the woods to learn about the biodiversity that teems there.

Most bird families have adapted to changes in ambient temperature by changing both their bodies and their bills simultaneously, according to biologist Justin Baldwin in Arts & Sciences, first author of a new study in Nature Communications.

A new analysis of fine particulate matter exposure led by researchers in Randall Martin’s lab in the McKelvey School of Engineering illuminates ways to improve health in India, Pakistan, Bangladesh, Nepal, Bhutan, Sri Lanka and Myanmar.

For the first time, a study by researchers including biologist Susanne Renner in Arts & Sciences helps solve the mystery of the timing of falling leaves in autumn by revealing the pivotal role of the summer solstice.

Researchers from Zhen (Jason) He’s lab at the McKelvey School of Engineering use advanced technologies to recover valuable resources from wastewater. They recently demonstrated a promising pathway to treat solid sludge and recover usable phosphorus.
