Back-to-the-Future Plants Give Climate Change Insights

Outdoor Labs Give Realistic Sense of Plant Response to Future Climate Change

If you were to take a seed and zap it into the future to see how it will respond to climate change, how realistic might that prediction be? After all, seeds that actually grow in the future will have gone through generations of genetic changes and adaptations that these “time traveling” seeds don’t experience.

New source of global nitrogen discovered

April 09, 2018

Rocks could hold key to carbon storage and improved global climate projections

For centuries, the prevailing science has indicated that all of the nitrogen on Earth available to plants comes from the atmosphere. But a study from the University of California, Davis, indicates that more than a quarter comes from Earth’s bedrock.

Walleye fish populations are in decline

Study a warning signal for popular game fish

Walleye, an iconic native fish species in Wisconsin, the upper Midwest and Canada, are in decline in northern Wisconsin lakes, according to a study published this week in the Canadian Journal of Fisheries and Aquatic Species.

Nearly Half of California’s Vegetation at Risk from Climate Stress

Slashing emissions to Paris Climate Agreement targets could reduce impacts 20-30 percent  

Current levels of greenhouse gas emissions are putting nearly half of California’s natural vegetation at risk from climate stress, with transformative implications for the state’s landscape and the people and animals that depend on it, according to a study led by the University of California, Davis.

Polarized Debate

Blogs on Polar Bears and Sea Ice Reveal Dangerous Gap Between Climate-Change Facts and Opinions

 

Human-caused global warming is accepted by leading scientific organizations around the world, but public opinion about humanity’s role fails to keep pace with these consensus views. Internet blogs contribute to this gap by casting doubt on iconic climate science topics, such as polar bears and sea ice extent, setting them up as “keystone dominoes” to topple scientific understanding.

The Social Cost of Carbon Doubles

November 27, 2017
Effects on Agriculture Cost up to $8.50 for Every Ton of CO2 Emitted, Updated Estimates Show  

The “social cost of carbon” — an influential figure used by policymakers to weigh the value of efforts that reduce greenhouse gas emissions — is outdated and underestimated. Updated estimates focused on the agricultural sector alone more than double the social cost of carbon, according to analysis from the University of California, Davis, and Purdue University.

Mitigating Climate Change with Mud?

UC Davis Team Chosen as Part of Resilient by Design’s Bay Area Challenge  

UC Davis faculty are part of a multidisciplinary design team chosen to develop solutions to strengthen the San Francisco’s Bay Area’s resilience to the impact of climate change, such as sea-level rise, severe storms and flooding.

The Last Stop: When There's Nowhere Colder to Go

How climate change is affecting polar fish at the tip of a warming world  

Fish have been migrating to cooler water over the last several decades as the ocean warms. But in Antarctica, the coldest place on the planet, polar species have nowhere to go.

Preliminary research by a UC Davis animal scientist shows that some polar fish have been able to acclimate to warm water or to higher levels of carbon dioxide, but not to both.

Earth’s Oldest Trees in Climate-Induced Race up the Tree Line

Bristlecone Pine Trees in Great Basin Are Losing Game of Leapfrog With Limber Pine

Bristlecone pine and limber pine trees in the Great Basin region are like two very gnarled, old men in a slow-motion race up the mountaintop, and climate change is the starting gun, according to a study from the University of California, Davis.
