Climate Change

An average of more than 1 million acres of idled farmland a year is a significant contributor to a growing dust problem in California that has implications for millions of residents’ health and the state’s climate.

Recently, more than 150 students at 10 high schools in Los Angeles, New York City and Washington, D.C. completed Climate Justice, a UC Merced course , through a unique partnership between the University of California and the National Education Equity Lab.

People don't think about dust much until it's time to clean the house, but a new report by UC researchers could raise awareness of the growing threat of dust and dust storms.

Dust affects everything from cardiovascular and brain health to traffic collisions and agricultural yield. “Beyond the Haze: A UC Dust Report on the Causes, Impacts, and Future of Dust Storms in California” details the wide-ranging impacts of dust on health, public safety, the environment and California's economy.

In 2020, the COVID-19 pandemic impacted many facets of life, including health care, schools and the work environment.

A new study by UC Merced researchers shows evidence that the pandemic also fueled an elevated number of wildfires in the United States that year.

How?

Pictures accompanying Professor John Abatzoglou's presentation on the 2025 fire season were blurry. That was intentional, he said, because so much about wildfire is unpredictable.

"There's a lot that we know, and a lot we don't know," he said.

The Biology Integration Institute (BII): The Institute for Symbiotic Interactions, Training and Education in the Face of a Changing Climate, or INSITE, stands out because it is supported by $12.5 million from the National Science Foundation, one of the largest NSF grants UC Merced has ever received.

UC Merced researchers are taking part in a comprehensive, multi-agency effort aimed at efficiently measuring and mitigating methane emissions.

IBM and Los Alamos National Laboratory are leading the effort, which earned a $20 million award from the U.S. Department of Energy in December.

Faculty members at UC Merced are taking the lead on four Multicampus Research Program Initiatives (MRPI), working with colleagues around the University of California system to address challenges around labor and agriculture, active matter, Indigenous health and fusion energy.

Measurements and data collected from space can be used to better understand life on Earth.

Sugar pines are the tallest pine species in the world, and they only grow along the West Coast of North America. They are a valued source of timber with cones as large as an adult’s forearm. But they face several problems that a new paper argues should be quickly addressed.

The sugar pine population has been declining because of changing fire patterns, drought, bark beetle mortality, a disease called white pine blister rust – and now the impacts of climate change.
