A New ARE Study Projects Growth Dividend from Comprehensive National Climate Policy
As the U.S. Senate debates clean energy and climate legislation, a new economic analysis finds that strong federal policy could stimulate both employment and income growth across the national economy. The new study was conducted by the University of California in collaboration with University of Illinois and Yale University and provides an in-depth, state-by-state examination of the impacts of three pillars of federal legislation: energy efficiency, renewable energy and limits on carbon pollution.
“This report shows that stronger federal energy and climate policies are compatible with economic growth,” said the report’s lead author David Roland-Holst, Adjunct Professor of Agricultural and Resource Economics at UC Berkeley. “Those who say we cannot afford to take action now may not understand the opportunity we stand to lose by not acting. By revenue, energy is the world’s largest industry, yet traditional energy use patterns have created unsustainable carbon liabilities that threaten all of us. The next great knowledge-intensive sector will arise in an emerging multi-billion dollar global clean energy market. To participate in this technology breakout, we need policies that price carbon risk responsibly and create appropriate incentives for investors and innovators.”
Using EAGLE, a new state-of-the-art forecasting model, the study assesses the detailed economic implications of climate and energy policies currently under consideration in Congress. On a state-by-state basis, the study models both moderate and aggressive implementation of policies that put a cap on carbon emissions, create a market based program to reduce carbon emissions, and standards for and investments in renewable energy and energy efficiency.
The study is available in summary form as a PDF: Report: New ARE Study Projects Growth Dividend.

Professor Honored for Outstanding Contributions to California Forestry
The California State Board of Forestry and Fire Protection presented the Francis H. Raymond Award for Outstanding Contributions to California Forestry to Dr. William Libby on October 7, 2009.
Dr. Libby is Professor Emeritus of Forest Genetics, having taught forestry at the College of Natural Resources in the Department of Environmental Science, Policy, and Management between 1962 and 1994. His pioneering work in the field of forest tree genetics is internationally recognized and respected. Dr. Libby has practiced forestry on several continents and is well known for his work with California’s coast redwood and Monterey pine trees.
Though he officially retired in 1994, Dr. Libby has continued to educate and enlighten across the borders of country and perspective. He currently sits on the Board of the Save the Redwoods League with a focus on promoting research on redwood forest disturbance effects and the impacts of climate change on California’s coast redwood and giant sequoia forests. Dr. Libby’s observations on state and national forest policy are reflective of his insight and intellectual curiosity. His dedication in service to the forests of California and elsewhere is inspirational.
“Dr. Libby’s contributions to decades of forestry students and fellow researchers cannot be
measured,” said George Gentry, executive officer for the Board of Forestry and Fire Protection.
The award is named for Francis H. Raymond who was the Director of the California Department
of Forestry and Fire Protection from 1953 to 1970. Mr. Raymond was one of the primary
advocates for the passage of the Professional Foresters Law in 1973. Since 1987 it has been
awarded to a group or individual who has achieved excellence in forestry in California.

Sierra Nevada birds move in response to warmer, wetter climate
If the climate is not quite right, birds will up and move rather than stick around and sweat it out, according to a new study led by biologists at the University of California, Berkeley.
The findings, to be published the week of Sept. 14 in an online early edition of the journal Proceedings of the National Academy of Sciences, reveal that 48 out of 53 bird species studied in California's Sierra Nevada mountains have adjusted to climate change over the last century by moving to sites with the temperature and precipitation conditions they favored.
The few species, including the Anna's Hummingbird and Western Scrub-Jay, that did not pack up and leave when the climate changed were generally better able to exploit human-altered habitats, such as urban or suburban areas, the researchers said.
In order to conserve biodiversity in the face of future climate change, we need to know how a species actually responds to a warming climate," said study lead author Morgan Tingley, a Ph.D. student in the Department of Environmental Science, Policy & Management and at the Museum of Vertebrate Zoology at UC Berkeley. "Comparing past and present ranges of species that experienced climate change is one of the best ways to gain this knowledge. Understanding how species will respond to climate change allows us to take steps now to restore key habitats and create movement corridors that will help them respond to the changes we have coming."

The Climate Gap (with Podcast)
| Hear the podcast from NPR's Living On Earth. |
"Climate change does not affect everyone equally in the United States," says Rachel Morello-Frosch, Associate Professor of Environmental Science, Policy and Management, and of Public Health at UC Berkeley and lead author of a new report on climate change. The report, The Climate Gap looks at the unequal harm climate change will have in the United States on people of color and the poor. Droughts, heat waves, poor air quality, floods, higher prices for basic necessities, and other challenges of climate change will have a disproportional impact on people of color and the poor.
The report also explores ways in which efforts to solve climate change and to close the “climate gap” can be combined. The report suggests many changes that should be made in government polices, including that government agencies at all levels should increase public participation in regulatory decisions at all levels to help counter imbalances in political power. That greenhouse gas emission reductions should be focused on neighborhoods that have the dirtiest air and on pollutants that may jeopardize public health and that green jobs and worker transition could be targeted to people of color and the poor.
To read more about Rachel Morello-Frosch's research on the “climate gap,” you can find recent articles in The Scientific American, The Huffington Post, and Scientific American Earth, or read the article in full The Climate Gap.

Uncovering the complex relationship between the forest and the atmosphere
This month, Nature profiles atmospheric chemist Allen Goldstein, (link - Nature subscription required | PDF - open access) who specializes in interpreting the scents of the forest. Goldstein has built his career on finding and characterizing some of the more elusive airborne chemicals in nature. For 10 years at the Blodgett Forest Research Station his team has described more than a dozen plant-released compounds that no one had previously measured or, in some cases, even known existed in the atmosphere.
The article expands upon themes we covered in the Fall 2007 issue of Breakthroughs magazine.
Goldstein also made a bit of a stir recently when his team found that the southeastern U.S. seems to be getting cooler while the rest of the globe is warming. The researchers used satellite and ground sensor data to track air pollution, and found that cooling induced by atmospheric haze has outpaced the warming due to rising carbon dioxide levels in that region.

Summer haze cools southeastern United States
Global warming may include some periods of local cooling, according to a new study by researchers at the College of Natural Resources. Results from satellite and ground-based sensor data show that sweltering summers can, paradoxically, lead to the temporary formation of a cooling haze in the southeastern United States.
The study, published the week of May 18 in the journal Proceedings of the National Academy of Sciences, found that when manmade pollutants mix with the natural compounds emitted from forests and vegetation during the hot summer months, they form secondary aerosols that reflect light from the sun. Such aerosols may also contribute to the formation of clouds, which also reflect sunlight.

Green leaders from the Bay Area: Chris Somerville
The San Francisco Chronicle recently highlighted plant biologist Chris Somerville, director of the Energy Biosciences Institute, among 10 Bay Area entrepreneurs, scientists and policymakers at the vanguard of a revolution that aims to reinvent the way people use water, power their cars, build their houses and live their lives.
"They might not become household names," wrote the Chronicle, "but their research, policy papers and startups could shape the way many households run in the years to come." The story continues:
As a plant biochemist, Chris Somerville has pioneered the search for clean liquid-fuel sources harnessed from the solar energy stored in nonfood plants. Somerville is director of the Energy Biosciences Institute at UC Berkeley, an ambitious project financed by a $500 million grant from BP, the British oil company. It is the world's largest alliance between industry and academia.Somerville has made the study of biofuels for transportation, along with the social, economic and environmental impact of such fuels, the institute's top priority.
His research teams are using global satellite imagery, geologic surveys and market databases to identify abandoned farmlands and nonagricultural soils that could support energy crops; trying to identify the plant species most suitable for biofuels; and using biotechnology laboratories to explore nature's methods of releasing plant sugars and to create synthetic catalysts."We're not in commercial development; we're trying to understand it first," said Somerville. "I feel optimistic. We're trying to push the frontier forward."

Climate Change to Spur Rapid Shifts in Fire Hotspots
Climate change will bring about major shifts in worldwide fire patterns, and those changes are coming fast, according to a first-of-its-kind analysis led by researchers at the College of Natural Resources, in collaboration with scientists at Texas Tech University.
The findings are reported in the April 8 issue of PLoS ONE, an open-access, peer-reviewed journal of the Public Library of Science.
Researchers used thermal-infrared sensor data obtained between 1996 and 2006 from European Space Agency satellites in their study of pyrogeography - the distribution and behavior of wildfire - on a global scale. They not only got a global view of where wildfires occur, but they determined the common environmental characteristics associated with the risk of those fires. They then incorporated those variables into projections for how future climate scenarios will impact wildfire occurrence worldwide.

Green Policies in California Generated Jobs
From the New York Times: "California’s energy-efficiency policies created nearly 1.5 million jobs from 1977 to 2007, while eliminating fewer than 25,000, according to a study to be released Monday."
The study, conducted by David Roland-Holst, an economist at the Center for Energy, Resources and Economic Sustainability at the University of California, Berkeley, found that while the state’s policies lowered employee compensation in the electric power industry by an estimated $1.6 billion over that period, it improved compensation in the state over all by $44.6 billion.

Warming in Yosemite National Park sends small mammals packing to higher and cooler elevations
Global warming is causing major shifts in the range of small mammals in Yosemite National Park, one of the nation's treasures that was set aside as a public trust 144 years ago, according to a new study by University of California, Berkeley, biologists.
The study, published in the Oct. 10 issue of Science, compared small mammal populations in the park today versus 90 years ago and found that mammals like shrews, mice and ground squirrels have moved to higher elevations or reduced their ranges in response to warmer temperatures, essentially shuffling the species living together in any one spot.
"We didn't set out to study the effects of climate change, but to see what has changed and why" since the last full-scale survey in Yosemite in 1918, said study leader Craig Moritz, UC Berkeley professor of integrative biology and director of the campus's Museum of Vertebrate Zoology. "But the most dramatic finding in the Yosemite transect was the upward elevational shift of species. When we asked ourselves, "What changed?" it hit us between the eyes: the climate."
Thanks to these detailed field notes recording not only when, where and what they saw and trapped but also what they failed to observe, the UC Berkeley biologists were able to perform a statistical analysis that makes the study results very solid, said coauthor and conservation biologist Steve Beissinger, UC Berkeley professor of environmental science, policy and management.
"One of the biggest problems we have when comparing the distribution of species now and in the past is false absences. If they didn't see something back then, is it because it wasn't there, or because it just wasn't detected?" he said. Employing occupancy models developed in the past few years, he added, "the Grinnell group's data allows us to go back and, night by night, reconstruct their trapping success for small mammals and develop a probability for detecting each species for Grinnell and for us. This is one of the first studies to use the model to look at climate change and historic changes in range."

Award-winning paper prescribes how to improve upon Kyoto
Larry Karp, professor of agricultural and resource economics, and Jinhua Zhao, an economist at Iowa State University (and Berkeley ARE Ph.D.) were recently named winners of the Harvard Project on International Climate Agreements research paper competition.
As reported in Breakthroughs last year, their paper proposes a design for a successor to the Kyoto Protocol.
"The successor to the Kyoto Protocol should impose national ceilings on rich countries' greenhouse gas emissions and promote voluntary abatement by developing countries," the authors write. "Our proposal gives signatories the option of exercising an escape clause that relaxes their requirement to abate. This feature helps to solve the participation and compliance problems that have weakened the Protocol. We support the use of carefully circumscribed trade restrictions in order to reduce the real or perceived problem of carbon leakage."

A Nobel Cause
Professor Barbara Allen-Diaz has always been a little ahead of the curve. After fast-tracking
through her M.S./Ph.D. at UC Berkeley in 4 years, Allen-Diaz was snapped up by the U.S. Forest Service, only to be lured back to Cal to become the first female range management faculty in the country. In the mid-1990s, she was tapped to participate in the second installment of a massive, international research effort called the Intergovernmental Panel on Climate Change, which had the prescient hunch that humans were having a significant impact on global climate.
That pioneering research culminated in the presentation of the Nobel Peace Prize to Al Gore and the IPCC's 2,000 scientists including Allen-Diaz and ESPM’s Inez Fung.
Allen-Diaz’s contributions focused on the effects of climate change on rangeland, which comprises 51% of the planet’s land surface. Among her team’s early findings were that changes in climate directly alter the species composition of landscapes, shifting the boundaries between rangelands and other ecosystems.

New analysis shows alarming increase in expected growth of China's carbon dioxide emissions
The growth in China's carbon dioxide (CO2) emissions is far outpacing previous estimates, making the goal of stabilizing atmospheric greenhouse gases even more difficult, according to a new analysis by economists at the University of California, Berkeley, and UC San Diego.
Previous estimates, including those used by the Intergovernmental Panel on Climate Change, say the region that includes China will see a 2.5 to 5 percent annual increase in CO2 emissions, the largest contributor to atmospheric greenhouse gases, between 2004 and 2010. The new UC analysis puts that annual growth rate for China to at least 11 percent for the same time period.

"Buy local" applies to forests, too
by Dean Keith Gilless
Frozen pipes never concern San Francisco residents, but Minnesotans insulate the pipes around their homes every winter. The West Nile virus scares many Californians but doesn't alarm Scandinavians at all. Where you are in the world goes a long way toward determining the things you worry about.
Some Californians shy away from using wood for fear of contributing to the deforestation so frequently associated with global warming. But relying on imported goods means burning fossil fuels to bring those goods to market, which increases greenhouse gas emissions. The arguments to promote "locally grown" are no more or less valid when considering one's consumption of lumber and other forest products.

China's Chance to Lead
This op-ed, by Assistant Professor Max Auffhammer and UCSD economist Richard Carson, originally appeared in the Washington Post on August 2, 2007.
China is about to emerge as the world's leading emitter of greenhouse gases, a position the United States has held since 1890. Now is the time for China to take the lead in finding a way to reduce global emissions, which the United States has thus far failed to do. It should start by imposing a sizable tax on the carbon content of its fossil fuel consumption and by heading an effort among other major trading countries to do the same.

How the Earth breathes is key to climate change
Looking out across an expanse of oak-grass savanna from the top of a 65-foot research tower near Ione in Amador County, biometeorologist Dennis Baldocchi [professor of Environmental Science, Policy and Management at] UC Berkeley sums up his part in the effort to get a more accurate picture of climate change.
"We want to see how the earth breathes, essentially," he said.
One of the pieces of the climate puzzle that hasn't come into focus yet is this flux of carbon between the earth and the atmosphere. How this interchange will be affected by changes in sunlight, temperature, rainfall and soil moisture is still a big gap in the climate models.

Relying on Berkeley research, California establishes groundbreaking carbon standard for fuels
Governor Arnold Schwarzenegger has issued an executive order calling for California to establish the world's first carbon standard for transportation fuels. (Read about it in the Governor's op-ed here.)
Relying on research by David Roland-Holst, adjunct professor in ARE, the governor writes:
The University of California estimates our greenhouse gas emissions goals will increase our gross state product by $60 billion and create more than 20,000 new jobs. The time is now for America to transition to a clean-energy economy.... I am very pleased to be able to announce that California is leading the way.

Study of rotting leaves could lead to more accurate climate models
Over the past decade, in numerous field sites throughout the world, mesh bags of leaf and root litter sat exposed to the elements, day and night, throughout the four seasons, gradually rotting away.
Now, those bags of decomposing organic matter have allowed a research team led by scientists from CNR and Colorado State University to produce an elegant and simple set of equations to calculate the nitrogen released into the soil during decomposition, which in turn could significantly improve the accuracy of global climate change models.

FAQ on Forest Carbon
There’s progress on the climate front. Suddenly the U.S. is waking to the reality of climate change as glaciers melt and seasons become more extreme. For California, predictions of declining snow packs and drier summers mean threats to urban water supplies and higher risk of wildfire. Across the country, states are taking the initiative to reduce greenhouse gas emissions.
Frequent questions arise about the California Climate Action Registry and its Forest Protocols. Forest landowners are starting to learn more and examine how the Registry might benefit them. Some misconceptions have developed, thus a brief overview helps in understanding how the protocols work and the potential they offer to landowners, forests and the global environment.

Forest landowners playing role in fight against global warming
By Andrea Tuttle
California's forests have something to celebrate.
The first forest projects in California designed specifically to fight global warming were recently announced at the United Nations conference on climate change in Montreal. By registering in the California Climate Action Registry, the Garcia River Forest in Sonoma County and the Van Eck property in Humboldt show a new model for protecting natural resources.
The projects will reduce greenhouse gases and restore streams and roads, all while working to produce timber. Perhaps most surprising is that well-known environmental groups, including the Conservation Fund, the Pacific Forest Trust, the Nature Conservancy and the State Coastal Conservancy, will actually manage logging on these lands to save them and better the environment.

Overfishing may drive endangered seabird to rely upon lower quality food
The effects of overfishing may have driven marbled murrelets, an endangered seabird found along the Pacific coast, to increasingly rely upon less nutritious food sources, according to a new study by biologists at the University of California, Berkeley.
The results, to be published online by early March 2006 in the journal Conservation Biology, suggest that feeding further down the food web may have played a role in low levels of reproduction observed in contemporary murrelet populations, and has likely contributed to the seabirds' listing as an endangered species, the researchers said.

UC gives tips for coping with heat stress
by Pam Kan-Rice
The heat-related death of a man harvesting peppers in Kern County last month is a tragic reminder of the dangers of heat stress.
To help reduce dangers of becoming overheated, a University of California Cooperative Extension specialist has produced a heat-stress information card for farmworkers that explains in English and Spanish how heat-related illnesses develop and how to avoid them.
Download a fold-up heat stress information card in English and Spanish (PDF)
More references about heat stress are available here.
Although the advice is directed at farmworkers, it is useful to anyone who works in the heat.
UC Berkeley-based agricultural personnel management specialist Howard Rosenberg warns that excess heat can impair the body even before a person feels ill. Symptoms of heat stress may include general discomfort, loss of coordination and stamina, weakness, poor concentration, irritability, muscle pain and cramping, fatigue, blurry vision, headache, dizziness, nausea, confusion, and unconsciousness (see "Heat illness symptoms and first aid" sidebar).
Although some of the heat that people have to deal with at work comes from the sun and ambient air, most heat is generated by their own bodies, Rosenberg says. "At rest the body produces little heat, but at work it demands more energy and faster metabolism, which greatly increases internal heat production," he explains.
To cool itself, the body first increases blood flow toward the body surface. This reduces the flow available to carry oxygen and nutrients to the muscles, brain and other internal organs, which in turn impairs strength, diminishes alertness and accelerates fatigue.
"When this mechanism doesn't release heat fast enough, sweat glands kick in," says Rosenberg. "They draw water from the bloodstream to form sweat that carries heat across outer layers of the skin and then evaporates." The loss of water through sweating impairs the body's ability to cool itself later, and the loss of electrolytes in sweat can cause muscle cramps.
The longer sweating goes on, the less blood volume remains and the greater the health risk. Rosenberg gives this cautionary example: a 150-pound man working moderately in warm weather would lose about 3/4 quart of water -- or 1 percent of his body weight -- per hour. At that rate, without replacing the lost fluid, he would likely experience diminished energy and endurance after three hours, serious fatigue and nausea after six hours, and loss of consciousness after eight hours (see "How heat affects the body" sidebar).
He recommends drinking water even before being prompted by thirst because thirst is a late signal of a water deficit. "Chugging to quench an intense thirst is like pouring water on a wilted plant," Rosenberg says.
For farm operations, Rosenberg recommends that managers and foremen try to keep drinking water containers as close as possible to centers of activity. If the water is too far away, such as at the end of a long row, workers may not want to take time away from their tasks or exert the extra effort to get to it.
Rosenberg also recommends bringing "a little heat-stress physiology 101 to the field" -- helping workers understand the causes of heat stress, their own bodies' heat release mechanisms, and the critical importance of replenishing the fluid they lose as sweat. "We hope the new card enables more growers to effectively deliver information that their employees need to know."
If workers begin experiencing heat stress symptoms, Rosenberg advises having them rest, preferably in a cooler area, and drink plenty of water or electrolyte fluids. In case of heat stroke, immediate medical attention should be sought.
AB 805, a bill pending in the California Legislature, would add specific heat-illness prevention and response requirements to employers' existing obligations for workplace safety. This month, after more than three inactive years, a Cal/OSHA advisory committee resumed its consideration of a new industrial regulation that would help prevent heat illness and injury in the workplace.
The card is being produced in cooperation with California Farm Bureau Federation, California Grape and Tree Fruit League, and California Association of Winegrape Growers, with additional USDA support through its Western Center for Risk Management Education.
