New book praising biofuels has an unexpected author

There are combinations that are just too weird: chocolate cake and grape juice (to steal from an old Dick Van Dyke show), or hearing the Rolling Stones' music used to market chastity belts and abstinence pledges. Or like seeing the Worldwatch Institute's name on a book praising biofuels ... the very fuels Les Brown, WWI's founder, is crusading against.

The gist of the book seems to be, "We need a completely different kind of biofuels than we have or are likely to ever see, but if that better, fairer system came along, it might be good for the poor." In other words, the Les-Brown-less WWI is now providing cover for people who don't give two burps about the poor, but sho' do love them some subsidies. And for people who will be throwing this book around the way Bush threw around Colin Powell's notorious UN speech on Saddam's "weapons of mass destruction."

New membrane technology for capturing CO2

Thursday event in D.C. seeks carbon questions

Gear up your brains and flex those diatribe muscles, carbon offset nerds -- the offset debate is coming to the Capitol, and you're all invited to participate.

Institute of Ecosystem Studies Dr. William Schlesinger is going to be speaking at 6:00 pm this Thursday on Capitol Hill in Washington, D.C., about his recent work on the interaction between forests and climate -- and its implications for how and whether carbon offsets should be allowed. I'm on the board of the American Lands Alliance, the organization sponsoring the event, and we'd like to get some hot questions to fire at Schlesinger -- which is where Gristmill's offset nerd legions come in. If you're an outside-the-Beltway climate nerd, feel free to ask questions in the comments section below. If you're an inside the Beltway climate nerd, you should just come.

Schlesinger, a member of the National Academy of Sciences, is one of the top authorities on this topic -- and he's shown a rare willingness, for a scientist, to venture into the policy and political arena. In 2005, for instance, he endorsed a carbon tax, calling it "potentially the most effective means to improve our energy-use efficiency and reduce carbon dioxide emissions." He also serves on the board of TerraPass, a company that provides offsets to people and corporations that pollute.

American Lands invited Schlesinger because we're very concerned about the impact a massive expansion in biofuels production could have on wildlands, in national forests and elsewhere. If we're cutting down ancient forests to grow woody biomass tree farms, it will be neither climate nor ecosystem friendly. But we're also intrigued by the possibility of allowing polluters to get carbon credits for protecting intact ancient forests. Conceivably, it could radically alter the financial incentives in national forests and elsewhere so that timber companies and others could make more money by helping restore forests than logging them. But, if not carefully managed, there's also potential for abuse. Such a system is largely dependent on having a robust cap-and-trade or cap-and-auction system in place as well; if we adopt a carbon tax, does that mean that forests and other native ecosystems won't benefit from the massive investments in tackling the climate crisis?

Notable quotable

Mercury moves from coal plant to fish dinner as fast as its name implies

A Scientificblogging post explains that it only takes three years for mercury emitted by coal-fired plants to travel up the food chain into fish that we eat:

"Before this study, no one had directly linked atmospheric deposition (mercury emissions) and mercury in fish," says study co-author Vincent St. Louis of the University of Alberta.

The experiment filled a major gap in scientists' understanding of how mercury moves from the atmosphere through forests, soils, lakes and into the fish that people eat.

It's immediate value is that it provides undeniable proof of a direct link, said St. Louis, who specializes in what is called whole-ecosystem experimentation.

He said it should spur policy-makers to enact regulations for more rapid reductions in mercury emissions by industry.

We had a lot of great stuff on the blog yesterday — so much that it was difficult to keep up. If you have time, go back and check out: Bill McKibben’s review of two new books on climate change politics, one by Bjorn Lomborg, on from Shellenberger & Nordhaus. Sierra Club head honcho Carl […]

Another positive feedback loop

Scientificblogging reports on the link between atmospheric water vapor and greenhouse gases:

The water vapor feedback mechanism works in the following way: as the atmosphere warms due to human-caused increases in carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons, water vapor increases, trapping more heat in the atmosphere, which in turn causes a further increase in water vapor.

Basic theory, observations and climate model results all show that the increase in water vapor is roughly 6 percent to 7.5 percent per degree Celsius warming of the lower atmosphere.

The authors note that their findings, when taken together with similar studies of continental-scale river runoff, zonal-mean rainfall, and surface specific humidity, point toward an emerging human-caused signal in the cycling of moisture between the atmosphere, land and ocean.

"This new work shows that the climate system is telling us a consistent story," Santer said. "The observed changes in temperature, moisture, and atmospheric circulation fit together in an internally- and physically-consistent way."

San Francisco plans hour of darkness for October

If you’ll be in San Francisco between 8 p.m. and 9 p.m. on Saturday, Oct. 20, be sure to have a candle handy. Green group Lights Out San Francisco is encouraging residents to turn off all unnecessary lights during that hour to raise awareness of energy use.

Discover Brilliant: Renewables + smart grid

Today at the conference, everyone’s broken out into small groups and are having more free-form discussions. Consequently, it’s somewhat more difficult to summarize. I’m hanging out for the day in the “State of the Union in Renewables + Smart Grid” room. I’ll try to pass along insights as they drift by. For now, there’s some […]

Rising blowback against wind power

Stumbled across an interesting site the other day -- an anti-wind power site.
