Droughtless in Seattle
It’s been both interesting and frightening watching the drought unfold across the country this spring and summer. It’s a very serious situation, and may be a harbinger and an affirmation of climate change. I believe it is.
Has it dawned on anyone else that the dry, hot summer the rest of the country has suffered through is exactly like what we Californians endure most years? Could it be the rest of the country will soon share our Mediterranean climate, of relatively wet, warm winters and summers of drought? Now THAT’s something to mull.
Of course, our West Coast climate is changing, too. Spring seems to arrive and leave sooner than in years past. The winter and spring rains seem to fall torrentially, rather than a few days here, followed by a few days to soak in, and on and on. And the often-sparse Sierra snowpack melts sooner in the year.
But because we in the West are adapted to our summer-drought cycle, we have built a good system of water storage to catch those spring rains and snowmelt. The Midwest, South and East Coast do not have this same system. No need when you usually have plenty of summer rain that soaks into the soil and keeps the rivers running high.
A recent family vacation to Seattle was an eye-opener for me. While there, I saw nightly news video of the drought-ravaged Midwest. Even the mighty Mississippi River was too low for some maritime traffic. Graphics were aired showing the extent of the drought. About the only place on the map of the continental U.S. that was not in drought was western Washington State (including Seattle), which has had an unusually wet and cool summer.
Maybe we should have looked at property while we were there. I could see a land rush happening in the region; it’s where most of the water is.

Growing a better stone fruit
The story centered around Kingsburg Orchards, one of the largest local tree fruit producers. The organization's board met recently to sample 30 experimental stone fruit varieties.
Kevin Day, UC Cooperative Extension advisor in Tulare County, said the push to find an edge in the marketplace is no surprise in today's highly competitive retail market.
"People are doing anything they can for product differentiation, including having exclusive varieties," Day said. "And the focus is really shifting to flavor."

Climate change is another reason to protect farmland
Rich Rominger and Renata Brillinger - Sacramento Bee
This op-ed piece references a new report released by the California Natural Resources Agency and the California Energy Commission that focused on a study by Louise Jackson and her team of UC Davis researchers. "Thanks to the team of UC Davis researchers and government funding for their study, we can add climate protection to the compelling list of reasons to invest in the long-term protection of California's farms and ranches," wrote the authors.
Progress reported in efforts to control growing threat to local and state citrus crops

Orozco interviews Ted Batkin of the Citrus Research Board and John Krist of the Ventura County Farm Bureau. In the six-minute story, Krist mentions work by Mark Hoddle, UC Cooperative Extenison specialist in the Department of Entomology at UC Riverside, to introduce natural enemies of Asian citrus psyllid to help bring down populations of the exotic pest.
UC research predicts climate change effects in California
The report, the third such assessment since 2006, provides new data to help Californians plan and adapt to climate change.
"Significant increases in wildfires, floods, severe storms, drought and heat waves are clear evidence that climate change is happening now. California is stepping up to lead the way in preparing for — and adapting to — this change," said state Secretary for Natural Resources John Laird. "These reports use cutting-edge science to provide an analytical roadmap, pointing the way for taking concrete steps to protect our natural resources and all Californians."
A study led by Louise Jackson, UC Cooperative Extension specialist in the Department of Plant Sciences at UC Davis, took an inventory of greenhouse gas emissions on Yolo County farmland and studied how agriculture can adapt to climate change.
An op-ed co-authored by Richard Rominger, a farmer and member of the UC President’s Advisory Commission on Agriculture and Natural Resources, and published in the Sacramento Bee noted the study “found that urban land accounts for 70 times more greenhouse gas emissions per acre than cropland.” A good reason to protect cropland.
The website based on the Jackson study provides a tool for Yolo County farmers and policymakers to plan for the changes that occur at the regional level with climate change.
For planning on a larger scale, a coalition of scientists and state agencies has developed Cal-adapt, a web-based climate adaptation planning tool. Cal-adapt allows users to identify potential climate change risks in specific geographic areas throughout the state. Users can query by location or click on an interactive map to explore what climate impacts are projected to occur in different regions of the state.
“Climate change is expected to affect the quantity and timing of water flow in the state,” explained Kaveh Madani, a former postdoctoral research scholar in UC Riverside’s Water Science and Policy Center, who led a research project on climate change effects on hydropower production, demand, and pricing in California.
“If California loses snowpack under climate warming, these high-elevation reservoirs might not be able to store enough water for hydropower generation in summer months when the demand is much higher and hydropower is priced higher,” said Madani, currently an assistant professor of civil, environmental, and construction engineering at the University of Central Florida. “California might, therefore, lose hydropower in warmer months and hydropower operators may lose considerable revenues.”
Max Moritz, UC Cooperative Extension specialist in the Department of Environmental Science, Policy and Management at UC Berkeley, contributed a paper to the extensive report about increased vulnerability to wildland fires in the state.
“The incredible breadth of studies, as well as the depth of their analyses, reveals just how much the University of California has to offer in preparing us all to adapt to a changing climate,” Moritz said of the full report.

Wildfires ignite debate on global warming
UC Cooperative Extension specialist Max Moritz has noticed that reporters are displaying a keen interest in the role played by global warming in what has so far been an unusually fierce 2012 fire season.
"For me, that marks a significant shift," wrote Moritz in a op-ed published in Nature yesterday. "This fresh curiosity about the link between fire and climate change is an important opportunity, of sorts."
Moritz, a wildfire expert in the UC Berkeley Department of Environmental Science, Policy and Management, is the author of a journal article published this summer in Ecosphere that linked climate change to global fire activity. The article is cited on a press release from U.S. House of Representatives Natural Resources Committee Democrats that calls for a hearing about reducing wildfire risk.
In the Moritz op-ed, he notes that a second common question from the press about the 2012 fire season is: “If these fires are related to climate change, what can we do about it?”
The inquiry, he said, reveals a growing anxiety over how humanity can adapt to the fire-related impacts of climate change, rather than how to mitigate climate change itself.
"To co-exist with fire will require extending our approach to living with environmental risks," Moritz wrote. "Mapping other natural hazards, such as flood and earthquake zones, has taught us to avoid building on the most dangerous parts of the landscape or to engineer solutions into the built environment when we do. Encouraging the 'right kind of fire' — with frequencies, sizes and intensities appropriate to the ecosystem in question — will be necessary, where possible, so that 'record-breaking' fires are less likely to occur during 'record-breaking' heat or drought."
For some people, climate change will become a fact only when its effects hit close to home.
UC scientist weighs in on climate change on VOA Russia
Common ground in the climate change debate can be found in agreement over the need to adapt to warmer temperatures, said Mark Lubell, a professor in the UC Davis Department of Environmental Science and Policy, during an interview with Rob Sachs of Voice of America Russia edition.
Lubell said there is a wide consensus among scientists that longterm climate models show a warming trend. There is less agreement about the cause of the warming temperatures, but most everyone would support the effort to make communities more resilient to the probable affects of a warmer planet.
Lubell said people need to be ready to adapt to more heat waves, a rising sea level and more fires in arid areas. He also discussed the potential repercussions of climate change on California agriculture.
"Climate change is likely to have a pretty big impact on water availability and the productivity of different types of crops," Lubell said "A farmer who says I'm just going to do what I've always done, 10 years from now might find himself with a much less profitable agricultural enterprise. If they try to change crops and the ways they manage their crop to be more in sync with climate change, they may be able to maintain their enterprise and profitability at the levels that they want."
Adapting to climate change is critical whether one believes it's human caused or not.
