Climate News Roundup

A few items in the climate news that caught our eyes this week…

1. CEC approves 250-megawatt solar thermal project in Kern County
The California Energy Commission approved the Beacon Solar Energy project on Wednesday. It’s the first time in 20 years that state energy regulators have approved construction on a solar thermal farm, the Los Angeles Times reports.

2. Geoengineering won’t curb sea-level rise, study finds
A new report from the Proceedings of the National Academy of Sciences finds that geoengineering strategies to combat global warming by blocking the sun’s radiation would not have much of an impact on rising sea levels, unless the efforts are extremely aggressive. (Read more at Nature.com)

3. Earth’s plant growth fell due to climate change, says NASA
After 20 years of increasing growth under warming temperatures, the Earth’s vegetation   saw a slight decrease over the last decade, according to a new NASA analysis.  Scientists reported they were surprised to find that the negative effects of regional droughts outweighed the positive influence of a longer growing season.

4. Another hurdle cleared for the world’s largest solar farm
Federal regulators are one step closer to approving plans for the 1,000 megawatt plant proposed by Oakland-based company Solar Millennium LLC.  The project would be located across more than 7,000 acres in Riverside County. (Read more at The New York Times.)

Feds to States on Global Warming Suit: Back Off

Bit by bit, the US Environmental Protection Agency is moving to limit the gases that scientists say cause global warming. Over five years, the agency is limiting auto emissions and is also requiring new industrial plants to use improved pollution controls

Sooooo, US Justice Department lawyers argue, California, seven other states, New York City and three land trusts should not be suing major utilities, demanding that they reduce global warming emissions.

In papers filed with the US Supreme court this week, Justice Department lawyers argue the authority to curb emissions that cause climate change belongs to the Environmental Protection Agency and to Congress. Continue reading Feds to States on Global Warming Suit: Back Off →

Another Mountain Critter Confronts Climate Change

The San Francisco-based Center for Biological Diversity (CBD) filed petitions with the US Fish and Wildlife Service today to protect four mountaintop species from climate change, including the San Bernardino flying squirrel.  The CBD is requesting that the species be listed as threatened under the federal Endangered Species Act and that critical habitat be designated.

The San Bernardino flying squirrel is a subspecies of the northern flying squirrel. Historically it has thrived in the high-elevation conifer forests of Southern California, in just two locations: the San Bernardino and San Jacinto Mountains.  But according to Shaye Wolf, a biologist at CBD, the species has likely disappeared from the San Jacinto Mountains in the past few decades. Studies indicate that the remaining population is isolated in the San Bernardino Mountains, which is bordered on the north by the Mojave Desert, a formidable barrier to migration.

Rebuilding a Buffer Against Climate Impacts

Hear our radio feature on wetlands restoration in San Francisco Bay, to be aired Friday afternoon on The California Report.

As my colleague Paul Rogers reported this week, earth has begun to move in the biggest wetlands restoration ever undertaken on the West Coast. This week I took a brief tour of the Eden Landing Ecological Reserve, near Hayward.

What is and what will be: Hundreds of acres of salt evaporation ponds, in the background, are being restored to tidal wetlands, as seen in the foreground of this scene from Eden Landing in Hayward. (All photos: Craig Miller)

Scanning much of the scene, “Eden” wasn’t exactly what came to mind. Vast, white expanses of salt and gypsum deposits are more reminiscent of Utah than a bay estuary. These are the remnants of a once booming salt harvesting industry.

But fueled partially by federal stimulus funding, bulldozers and backhoes are now reshaping levees there as part of the larger South Bay Salt Pond Restoration Project, which will eventually return 630 acres of abandoned salt flats into tidal wetlands at Eden Landing, and thousands more in an arc around the south end of San Francisco Bay.

Clean Energy from Below

UPDATED with interactive map

Hear my radio feature on geothermal energy and the rest of a five-part collaboration on renewable energy between NPR and KQED, on NPR’s Morning Edition.

It may be a distant second to California now, but Nevada is making a run to become the nation’s largest producer of geothermal energy.

California still produces an estimated 80% of the nation’s geothermal power (used to produce electricity*), with more than 40 plants online. But according to a summary from the Geothermal Energy Association (GEA) this summer:

“Nevada could become the leading geothermal energy producer in the coming years if growth and production trends continue on their current trajectories. Nevada’s 86 planned or developing geothermal power plants have the potential add up to 3,686.4 Megawatts of geothermal power to Nevada’s energy portfolio, power for 2.6 million homes – enough to meet the electricity needs of 100% of the homes in the Las Vegas metropolitan area.”

GEA describes 14 Nevada projects as being “in latter stages of development.” Meanwhile, says the group’s executive director, Karl Gawell, development in California is slowing down. “Everything’s relative,” Gawell told me in a phone interview. “Projects are moving forward in California, they just take longer.” Continue reading Clean Energy from Below →

The Overspray from Prop 23

On Monday, US energy secretary Steven Chu became the latest high-profile voice against California’s Proposition 23, the statewide initiative to suspend AB 32, the state’s four-year-old climate strategy.

“AB 32 was a good bill and continues to have California in a leadership role in developing clean energy and the efficient use of energy,” Chu told reporters at a dedication in Menlo Park. “From the middle 1970s California played that role and it would just be a terrible setback.”

Last week the trend was given full voice by Mary Nichols, who, as chair of the California Air Resources Board (CARB), is charged with getting AB 32 fully implemented in the next two years, called Prop 23 a “very serious threat,” not just to the core programs of AB 32, but to an array of regulatory programs that support the state’s attack on greenhouse gases.

Heat Records Set in 17 Countries — So Far

This post also appears at Climate Central, a content partner of Climate Watch.

By Andrew Freedman

California’s freakishly cool summer has been bucking a global trend this season. You’ve seen the headlines from Moscow and Pakistan–but that’s just part of the story. 2010 has featured several extreme heat events, as well as record flooding, in many countries worldwide. The number of countries that have set new national records for the warmest temperature recorded — 17 — would beat the old record of 14, provided that all of the new records are verified by meteorological agencies. According to meteorologist Jeff Masters of the private weather forecasting firm Weather Underground in Ann Arbor, Michigan, the countries that have set new records thus far this year comprise about 19 percent of the earth’s surface area.

Nichols: No Solo Cap-and-Trade

1 Comment

Cap-and-Trade is a lonely business these days. But according to the state’s top regulator in charge of implementing it, California won’t go it alone.

Mary Nichols, who chairs the state’s Air Resources Board, made the remark in a Silicon Valley panel discussion today. The ostensible topic of the event was renewable energy but it turned into a pep rally against Proposition 23, the statewide ballot measure designed to halt California’s comprehensive climate law, AB 32. Nichols was joined on the panel by executives from Google, PG&E and venture capitalist Vinod Khosla, all of whom voiced strong opposition to Prop 23.

When asked about the cap-and-trade provisions of AB 32, Nichols said: “We won’t launch this program without partners to trade with. It doesn’t make sense for an economy even as big as California, to try to do this all by ourselves.” The comment came days after congressional leaders threw in the towel for the summer, on a federal bill to address climate change and energy security. “To get the kind of leverage that you really need to make this program succeed, the US has got to step in,” said Nichols.

California is part of a nascent regional trading pact known as the Western Climate Initiative. But among the seven US states and four Canadian provinces signed on to the WCI, only California, New Mexico and Quebec are prepared to move forward with a working carbon trading market. Others still lack enabling legislation, and Arizona has overtly pulled out of the carbon trading plan, raising the question of how many “partners” California will have, even with WCI in the mix.

“I don’t expect to be faced with this dilemma,” Nichols told me after today’s event, “but if the worst were to happen and none of these states were able to move forward with their own programs, I think we would think long and hard about whether we would actually start enforcing the program, unless and until we were really confident that our  state had the ability to do it in a way that would not put us at a competitive disadvantage.”

Proponents of Prop 23 contend that full implementation of AB 32 will give other states and nations a competitive edge over California, resulting in “leakage” of jobs and businesses to regions with fewer regulations.

The panel, entitled “Electric Bills and Oil Spills: Will California Continue To Be a Clean Energy Leader?” was held on the Google corporate campus in Mountain View.
