The latest and greatest science blogging is available at Tangled Bank 54, hosted this fortnight by Get Busy Livin', or Get Busy Bloggin'.
This is will be my final post at islandofdoubt.blogspot.com. I know I've promised that before, but it looks like the webheads at my new home, Scienceblogs.com, are finally ready to launch their new collection of science bloggers. Beginning noon EDT, Friday, June 2, 2006, The Island of Doubt moves to scienceblogs.com/islandofdoubt. I will also switch the autoforwarding for islandofdoubt.net to the new page. 06 June 2006Ann Coulter: Court Jester
Via the J-Walk Blog and John Lynch's Stranger Fruit, comes the latest eruption from Ann Coulter, who's got yet another book out today. I've always considered Coulter one of the wackier examples of right-wing winnuttery, but worth paying attention to because so many other people do just that.
I don't know what to think of her latest comments on evolution, as told to her ideological compatriots at the Cybercast New Service. If they came from anyone else, I'd dismiss them as parody. So convoluted are her answers that we'd best take them one a time. Cybercast News Service: Most people consider evolution to be a branch of science, or at least a scientific theory, yet in "Godless," you refer to it as a "cult" and a "fetish." What is your basis for calling it that?Rarely has there been just a sweeping dismissal of an entire field of knowledge. No evidence at all. Usually we're just told that the evidence is weak. We don't have enough fossils, the missing links are still missing, that sort thing. But not Ann. There is no evidence. Period. Then we're told it's not disprovable. We all know that's not true. But I must at least acknowledge that Ann may be familiar with the Popperian notion of falsifiability. She doesn't understand it, but she must have read it somewhere, and that puts her ahead of most of the creationists. Part two, now: Cybercast News Service: Creationism is not considered a science because it can't be observed or empirically tested. You assert in your book that the theory of evolution has the same problems. Why then has the U.S. public school system been willing to accept the theory of evolution, but snubbed creationism?Hmmm. First, it would appear that evolution has a lock on the public education because, well, it has a lock on public education. A tautology at least is easy to analyze. But then we learn that it is not possible to not believe in god without believing in evolution. So everyone who doesn't believe in god must believe in evolution. So if you are too young or too poor or too ignorant to know about evolution, you have to believe in God? Wow. That's amazing. What a great way to get rid of atheists: just stop teaching them anything. Or maybe I just don't understand Ann's diabolical logic. Maybe I'll have to buy her book and parse her arguments. Right. I'd rather stick needles in my eyes. 02 June 2006Wind power vs. the War Machine
In a sure sign of desperation, the NIMBY forces aligned against wind power -- wherever it might be -- have enlisted the support of the Department of Defense. According to the Chicago Tribune's Michael Hawthorne, "The federal government has stopped work on more than a dozen wind farms planned across the Midwest, saying research is needed on whether the giant turbines could interfere with military radar."
Hawthorne's story quotes wind power advocates who allege the radar argument is really a smoke screen for "a group of wealthy vacationers who think a proposed wind farm off the coast of Cape Cod in Massachusetts would spoil the view at their summer homes." There's no solid evidence for that, but it's as good a guess as anything else, given the weakeness of the radar claim. Big nasty wind turbines, so the argument goes, casts a "radar shadow"that could make it impossible for nearby military -- and civilian -- airport radar systems to detect aircraft. If that strikes you as a little dodgy, give yourself a gold star. The same complaints were raised in the U.K. a while back, and so the eggheads at the people's R&D corporation, Qinetiq, were asked to look into it. This they did. And what did they find? You can read a summary of their report here. The short answer is, not much. While there is a theoretical threat of interference with conventional radar arrays, careful design, orientation and siting should be able to take care of any problem: Single wind turbines do not create a significant ‘radar shadow’. Any shadow region is only dark to a distance of a few hundred metres behind the turbine. Beyond this there is some reduction of the radar power, and a time-variation, but these will not prevent detection except possibly for very small targets.Of course, the radar shadow presented by any wind farm is proportional to the number of turbines. And some of the proposals on the drawing board, including the Nantucket project that so enrages Ted Kennedy et al., involve large numbers of turbines. But to freeze development of a dozen different projects is overreacting. A little consultation with the local military brass, a few computer simulations and Bob's your uncle-- potential conflicts resolved. Instead, everything's ground to a halt, thanks in large part to U.S. Sen. John Warner (R-Va.), a Cape Wind opponent who happens to chair the Senate Armed Services Committee. According to the Trib, he recently added a one-sentence amendment to a congressional order that directs the DoD to study "whether wind towers could mask the radar signals of small aircraft." I have to agree with Michael Vickerman, executive director of RENEW Wisconsin, a non-profit group that promotes renewable power."This is a big, ugly political maneuver by a handful of people who are undermining America's energy security," he said. Wind power isn't the answer to all our energy woes. But it could play a significant role in a medley of alternatives that are just waiting for the chance to compete fairly with heavily-subsidized fossil fuels. In any event, don't you think the military has more important things to do these days? Science 'Toons
The Union of Concerned Scientists is running a contest for editorial cartoonists:
Science Idol: the Scientific Integrity Editorial Cartoon ContestThe visual arts aren't really my strength. Quite the opposite. But I'm sure there's more than a few candidates hip to the science culture wars. 01 June 2006What's the point of arguing?
The 1997 recipient of the Royal Society's Michael Faraday prize for communicating science to the public isn't going to take it any more:
A leading British scientist said yesterday that he had given up trying to persuade creationists that Darwin's theory is correct after repeatedly being misrepresented and, he said, branded a liar. That from the Guardian of May 30. So where does that leave British biologists hoping to stem the rising tide of silliness? 31 May 2006Poison ivy is sexy
Research linking climate change with poison ivy isn't the only newsworthy story to be found in the latest issue of the Proceedings of the National Academy of Sciences, but it's easy to understand why it's the only one to attract heaps of media attention this past week.
What editor could resist running a story that says global warming will make poison ivy grow faster and nastier? Everybody understands the evils of poison ivy. I've got a bad case of Toxicodendron dermatitis, as it's technically known, right now. Probably picked it from the dog. It's such an easy sell that you could be excused for dismissing the whole thing as just a cynical attempt to attract attention. Kind of like the way environmentalists exploit the plight of polar bears, pandas, and other charismatic megafauna to galvanize support for their latest campaigns. (Not that that's necessarily a bad thing, although it is dishonest to imply that big cute animals are more worthy of saving than worms and other attractive, but ecologically important species.) Anyway, the good news the poison ivy story is worth your time. I asked the study's lead author, Jacqueline Mohan of Harvard University and the Marine Biological Laboratory in Woods Hole, why she chose poison ivy, and not another plant. Kudzu, perhaps? She replied that poison ivy (Toxicodendron radicans) is "a fascinating species ecologically, chemically, and, unfortunately for us, medically." Most of the media coverage dealt exclusively with the medical implications: more of us are going to run into the stuff, because it grows better This is kind of sad news, not only for humans but for forests," Mohan said. "Increased vine abundance inhibits tree regeneration by killing young trees," she added. I say Mohan and her colleagues are making an important contribution to our understanding of the just how unpredictable the ecological effects of a warming planet are going to be. They are not alone. The current edition of SEED magazine includes a frightening feature on researchers in Costa Rica who are finding the opposite effect of more CO2. Down there it could actually slow the growth of trees in the rainforest, and eventually cause them to emit more CO2 as they decay. We could see more of examples of positive feedback in addition to whatever happens to tropical rainforests. For one thing, melting permafrost could release vast quantities of methane, which is 20 times as effective at trapping heat as CO2. One of the overlooked PNAS papers just published concludes that oceanic coral reefs "may be more susceptible to climate change" than their continental counterparts -- a distinction that may surprise more than a few marine ecologists. On the other hand, there could be some negative feedback from cloud cover, and even a few good-news developments in the form of lengthened growing seasons here and there. Anyway, it now looks like woody vines could invade new territory. Noting that other species in the Anacardiaceae family, including mango, cashew, and pistachio, also can be allergenic, Mohan's paper suggests it is "possible that these plants, too, may become more problematic in the future." Great. Who thought more mangos could be bad thing? The point is reliable big-picture, ecosystem-level predictions are a long way off. The poison ivy story just reminds us how little we know. And why what lies ahead could just as easily be worse than we expect as anything else. The last word comes the Health Day News story: "The most worrisome message here is less about this particular plant and more about the whole forest," said Dr. David L. Katz, an associate professor of public health and director of the Prevention Research Center at Yale University School of Medicine. "We are upsetting a balance in ecosystems and that will have far-reaching effects, many of which we are first now beginning to guess," Katz said. 27 May 2006"Clouds are hard"Bill Gray is not a young man. But he does sound like an angry young man. One who can't abide the foolish ways of his This coming Sunday's Washington Post Magazine includes almost 7,500 words on Gray and his arguments. It's not a quick read, but it's worth it. What begins with a subhead that hints at sympathy for the skeptic's case -- warning of some "serious blowblack" -- plays out very differently in the end. Achenbach covers just about every familiar argument against climate-change consensus, respectfully, and then quite neatly demolishes them. My favorite line from the story comes from a section "in praise of uncertainty." Isaac Held, a NOAA climate modeler, has this to say about the imperfection of computer simulations: "Clouds are hard." Love that one. More importantly, Achenbach provides context. Lots and lots of context: LET US BE HONEST about the intellectual culture of America in general: It has become almost impossible to have an intelligent discussion about anything. And that, as they is say, is the real problem. Tip of the hat to Roger Pielke Jr. for finding what should be required reading this weekend and alerting us to its early web publication. |
