UC Davis Releases 5 New Wine Grape Varieties

December 18, 2019
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.

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.    

Bats May Benefit From Wildfire

Fire Plays Important Role for Sierra Nevada Bats

Bats face many threats — from habitat loss and climate change to emerging diseases, such as white-nose syndrome. But it appears that wildfire is not among those threats, suggests a study from the University of California, Davis, published today in the journal Scientific Reports. It found that bats in the Sierra Nevada appear to be well-adapted to wildfire.

The Genetics of Drought Tolerance in Bioenergy Poplar Trees

August 23, 2019

Bioenergy crops are central to climate mitigation strategies. This includes their use in BECCS (Bioenergy with Carbon Capture and Storage) and biomass supplied for heat, power, liquid fuels and in the future, biorefining to chemicals. It has been predicted that bioenergy will be the fastest developing renewable resource over coming decades, but at the same time, land use for bioenergy production can be controversial if it has negative impacts on land for food, or is detrimental to a wide array of ecosystem services.

Compost Key to Sequestering Carbon in the Soil

Study Dug Deep to Uncover Which Agricultural Systems Store the Most Carbon

By moving beyond the surface level and literally digging deep, scientists at the University of California, Davis, found that compost is a key to storing carbon in semi-arid cropland soils, a strategy for offsetting CO2 emissions.

Chancellor Backs Climate and Innovation Efforts

Chancellor Gary S. May recently signed higher education’s “Climate Emergency Letter” and took up his duties on the National Commission on Innovation and Competitiveness Frontiers.

●︎ Climate Emergency Letter — As of today (Aug. 9), the letter had been signed by 138 institutions representing approximately 2.3 million students, and 41 higher education networks representing nearly 8,300 institutions. The signatories include all 10 UC campuses as well as UC system as a whole.

Climate Change Could Shrink Oyster Habitat in California

August 05, 2019
Ocean Acidification Just One of Several Climate-Related Threats for Shellfish

Ocean acidification is bad news for shellfish, making it harder for them to form their calcium-based shells. But several other factors related to climate change could also make California bays less hospitable to shelled organisms like oysters, which are a key part of the food web.

Fertilizer Feast and Famine

Solving the Global Nitrogen Problem

Commercial organic and synthetic nitrogen fertilizer helps feed around half of the world’s population. While excessive fertilizer use poses environmental and public health risks, many developing nations lack access to it, leading to food insecurity, social unrest and economic hardship.
