As Americans Shelter in Place, Traffic, Emissions and Fuel-Tax Revenues Decline Dramatically

COVID-19 Mitigation Efforts Could Put U.S. on Track to Meet Paris Climate Accord Goals

Americans drove drastically less, saved millions of metric tons of greenhouse gases, and, in some states, lost millions in fuel-tax revenue since COVID-19 mitigation efforts took effect in early March. That is according to the latest special report from the Road Ecology Center at the University of California, Davis.

Concrete Solutions That Lower Both Emissions and Air Pollution

Air Quality and Climate Change Intertwine in Unexpected Ways. A Concrete Example.

Sometimes, fixing one problem can create another.

Concrete production contributes 8 percent of global greenhouse gases, and demand continues to rise as populations and incomes grow. Yet some commonly discussed strategies to reduce the sector’s global GHG emissions could, under some scenarios, increase local air pollution and related health damages, according to a study from the University of California, Davis.

Study Examines Environmental Footprint of California Dairy Cows Over 50 Years

UC Davis Researchers Find 50 Percent Reduction in Greenhouse Gases Per Liter of Milk

Producing a liter of milk in California emits less greenhouse gas and uses less land and water than it did in 1964, according to a recent study from researchers at the University of California, Davis.

California Agricultural Employers, Workers Approach Smoke Concerns Differently

UC Davis Examines Health and Safety Awareness Around Mounting Threat

In 2018, California wildfires burned more than 1.8 million acres and caused smoke to drift hundreds of miles. As the frequency and intensity of wildfires increases with climate change, California agricultural workers are at greater risk of smoke exposure as they often have no option but to work outdoors.

UC Davis Releases 5 New Wine Grape Varieties

Plants Are Resistant to Deadly Pierce’s Disease

For the first time since the 1980s, University of California, Davis, researchers have released new varieties of wine grapes. The five new varieties, three red and two white, are highly resistant to Pierce’s disease, which costs California grape growers more than $100 million a year. The new, traditionally bred varieties also produce high-quality fruit and wine.

Outlook for the Polar Regions in a 2 Degrees Warmer World

International Team Assesses Widespread Effects of Polar Warming

With 2019 on pace as one of the warmest years on record, a major new study from the University of California, Davis, reveals how rapidly the Arctic is warming and examines global consequences of continued polar warming.

The study, published today in the journal Science Advances reports that the Arctic has warmed by 0.75 C in the last decade alone. By comparison, the Earth as a whole has warmed by nearly the same amount, 0.8 C, over the past 137 years.
