As drought dries the landscape and rising global temperatures make for decreasing crop yields, farmers are faced with the question of how to feed billions of people in a way that both reduces global greenhouse gas emissions and adapts to the realities of climate change.
Scientists and policymakers from around the world will gather today through Friday, March 20-22, at the University of California, Davis, to grapple with the threats of climate change for global agriculture and recommend science-based actions to slow its effects while meeting the world's need for food, livelihood and sustainability.
In the aftermath of Hurricane Sandy, climate change and global greenhouse emissions are a hot topic these days. Dozens of UC Davis scientists study many facets of the causes and consequences of global warming.
One of them is Frank Mitloehner, UC Cooperative Extension specialist and professor in the Department of Animal Science at UC Davis. Mitloehner has studied the role of the livestock industry in contributing to greenhouse gas emissions. Mitloehner was recently selected to chair a United Nations committee to measure and assess the environmental impacts of the livestock industry.
As chair of the new Food and Agriculture Organization of the United Nations (FAO) committee,...

Global warming promises to be among the most immense challenges to human adaptation in history, as big as social media. But the climate topic has been overshadowed in recent years by the recession. Just as the Dow Jones can’t be described by the fluctuations of a single decade, climate science is not defined by periods less than centuries.
These thoughts were shared at a breakfast Oct. 16 at UC Davis hosted by Capital Public Radio. The speaker: Ben Santer, MacArthur Fellow (1998), National Academy Member (2012), and atmospheric scientist at Lawrence Livermore National Laboratory.
Santer said that when he hears about the tragedy of burdening youth with the national debt, he would like to hear more...

California must continually increase its use of renewable fuels to meet mandated reductions in greenhouse gas emissions (GHG). The state's historic Global Warming Solutions Act of 2006 (AB32) requires that alternative fuels displace 6 percent of gasoline and diesel use now, and 9 percent by 2012. The number goes up to 11 percent in 2017 and 26 percent in 2022.
California has been meeting these goals by importing millions of gallons of ethanol: 80 percent of the supply is corn ethanol from the Midwest, 12 percent is sugarcane ethanol from Brazil, and the rest is ethanol from corn grown here. By 2012, demand for ethanol fuel will rise to 1.62 billion gallons per year. If California does not increase its production of corn for...

All bets are off in terms of what will happen with plant species migration and crop production as the climate changes globally.
A common assumption has been that native plants and animals would “move,” or migrate, to higher elevations as temperatures rise, to maintain their “preferred” temperatures, but a new report by Jonathan Greenberg at UC Davis, shows that many California plant species moved downhill over the past 70 years.
According to Greenberg, “While the climate warmed significantly in this period, there was also more precipitation. These wetter conditions are allowing plants to exist in warmer locations than they were previously capable...
