Statistician contests George Will’s misguided climate op-ed
Nate Silver, the statistician who blogs at fivethirtyeight.com and made national news (and the Colbert Report) last year by being the most accurate and reliable predictor of the presidential election results, has turned his attention to climate change. In response to an op-ed yesterday by George Will in the Washington Post, Silver analyzes temperature trends and debunks the idea that there was a "global cooling" trend either in the 1970s or over the past century, or...
CONTINUE READINGWhich oysters for the Chesapeake Bay?
Sunday's Washington Post reports that a decision is expected soon on whether to deliberately introduce the Suminoe oyster, native to China and Japan, to the Chesapeake Bay. A decision would mark the end of an analytic process that has been going on for more than 10 years. The U.S. Army Corps of Engineers issued a draft EIS last fall considering the impacts of several alternatives, including release of fertile Suminoe oysters and confined aquaculture of sterile oysters...
CONTINUE READINGLaws as data
Julie Ekstrom, a doctoral student at the Bren School of Environmental Science and Management at UC Santa Barbara, has put together and made publicly available a searchable dataset of federal and state statutes and regulations dealing with ocean and coastal resources in the California current ecosystem. In a paper in the journal Marine Policy (subscription required), Ekstrom describes the derivation of the database. In another paper in the same journal issue, she and a gr...
CONTINUE READINGClimate change is outpacing most dire models
The Washington Post reports today on Chris Field's presentation at the annual meeting of the American Association for the Advancement of Science, in which he said: "We are basically looking now at a future climate that's beyond anything we've considered seriously in climate model simulations." Faster development of coal-fired electrical power in developing countries is part of the reason, as are serious positive feedback loops in carbon emissions (release of methane a...
CONTINUE READINGA Glimpse Inside the Stimulus Bill
Although the stimuls bill passed last week, there still doesn't seem to be a lot of detailed information about its exact provisions. It does appear, however, that the final legislation has considerable benefits for clean energy, as CNN details: Energy firms may reap the biggest rewards from the package, which is flush with dollars for investment in renewable energy and smart grid technologies. The bill includes $11 billion to improve the electric grid, including to p...
CONTINUE READINGThe future of coal-fired electric power
Tomorrow's New York Times has an interesting article on the future of coal-fired electric power in the United States. Coal is responsible for fully 20% of greenhouse gas emissions worldwide, according to the Pew Center on Global Climate Change. "Clean coal," meaning coal plants that result in no net emissions of carbon dioxide, would be possible only with successful implementation of technology to capture and store all the carbon dioxide produced by coal-fired pow...
CONTINUE READINGA smorgasbord of smelt and salmon news
There have been several developments in the Delta water saga since I posted on the request for relief from water quality standards submitted by the state Department of Water Resources and federal Bureau of Reclamation, and the potential for conflict between the water needs of smelt and of salmon. First, the State Water Resources Control Board has scheduled a hearing on that request for Tuesday, Feb. 17. The California Sportfishing Protection Alliance "vehemently oppos...
CONTINUE READINGThe Environment and Your Sex Life
This being Valentine's Day, it seemed like a good time for a posting on endocrine disrupters. Not being an expert on the topic, I first turned to the EPA's website. There I was reminded that a 1996 statute requires EPA to screen chemicals for this effect. Proceeding at its usual hectic pace, ten years later the EPA is still trying to figure out which chemicals to test. As helpful background, EPA does explain: In recent years, some scientists have proposed that ch...
CONTINUE READINGDo as I say, not as I do
Scientists are often in the news complaining that governments are not doing enough to solve environmental problems, especially the problem of climate change. But some scientific stonethrowers own houses may be made of glass. In the latest issue of Environmental Science and Technology, staff scientist Evan Mills of Lawrence Berkeley National Laboratory writes that the practice of science is often less than sustainable. Many laboratories are energy hogs, up to 10...
CONTINUE READINGThe Reverse Wimpy Effect
Does anybody remember Popeye? His friend Wimpy liked to say, "I would gladly pay you Tuesday for a hamburger today!" The Missouri Legislature is considering pulling a Reverse Wimpy. The Jefferson City solons are considering a bill that would let an electric utility say "I would gladly give you a power plant "tomorrow" if you will pay me "today". Should we care? The conventional approach is to start paying a regulated utility for a new power plant only after it ha...
