What? TED vectoring pseudoscience? Unpossible! In one recent particular instance, though, a TED talk firmly grounded in bullshit — literal and figurative — is gaining a mortifying amount of traction with people who really should know better. The lecturer is Allan Savory, who for the last couple decades has been pushing his own brand of Maverick Science despite hidebound opposition from “scientists” with their “peer review” and their “evidence” and their “reproducible results.” Savory’s thesis: every desert in the world is caused by insufficient grazing. We know this because of reasons. All those desertified former grasslands in Africa and the Middle East that have been turned to dusty parking lots by cattle and sheep and goats just didn’t have enough livestock on them to churn up the soil, shit everywhere, and then move on to the next patch of land in a rotational grazing approach. Savory’s approach can work in theory, on marginal grassland with very close monitoring and if your management goals do not include protecting species that are intolerant of cattle. Can work.  Doesn’t necessarily. And that’s irrelevant to actual deserts, yet Savory wants to push his approach onto ancient desert landscapes anyway. The biggest problem for me, as I point out this morning at KCET, is that Savory doesn’t distinguish between actual deserts — stable, diverse yet fragile habitats — and ruined grasslands. He conflates “desertification” — a term that needs to be abandoned — with actual deserts, then misrepresents the basic science  of desert ecology, for instance calling cryptobiotic crusts a “cancer.” None of this is a surprise to anyone who has followed Savory over the last few decades. Same shit, different day. But TED has helped him go viral, and there are people who are taking him at his word to an embarrassing...

This is really a thing of beauty: climate pseudoscientist Willis Eschenbach whines at the inadvertent comedy blog Watt’s Up With That that Bora Zivkovic has been moderating comments on his SciAm blog. Eschenbach, who’s also a Mass Extinction denialist, objects to Bora’s having instituted some basic anti-troll measures at A Blog Around The Clock that relegate comments with certain field marks of the climate denialist loon to the spam bin. Says Bora, in a passage that apparently made Eschenbach’s cranial temperature spike like a Warmist hockey-stick graph: If I write about a wonderful weekend mountain trek, and note I saw some flowers blooming earlier than they used to bloom years ago, then a comment denying climate change is trolling. I am a biologist, so I don’t write specifically about climate science as I do not feel I am expert enough for that. So, I am gradually teaching my spam filter to automatically send to spam any and every comment that contains the words “warmist”, “alarmist”, “Al Gore” or a link to Watts. A comment that contains any of those is, by definition, not posted in good faith. By definition, it does not provide additional information relevant to the post. By definition, it is off-topic. By definition, it contains erroneous information. By definition, it is ideologically motivated, thus not scientific. By definition, it is polarizing to the silent audience. It will go to spam as fast I can make it happen. What Eschenbach doesn’t mention, and a basic point of Bora’s post on how trolls derail substantive conversation, is that climate denialism is just the most pernicious and prevalent of a number of kinds of pseudoscience that have afflicted some of the sites on SciAm of late: I know that I used the example of Global Warming Denialism here the most – mainly because it is currently the most acute problem on our site – but the same goes for people harboring other anti-scientific ideas:...

Having reviewed my schedule for my Bay Area visit, including the fact that Tuesday evening will likely be mainly consumed with helping my Dear Old Mom celebrate her 40th birthday,* I have concluded that I will be having a beer at the Jupiter in Berkeley starting at approximately 5:30 on Wednesday the 27th. The Jupiter is close to the Downtown Berkeley BART station. As the bearded hippie, I will be easy to spot. Hope to see you there. In other news, I gave my old growth desert lecture a couple weeks back here in town, and a report on that lecture has just shown up in the local press. The reporter, a lovely person, got a couple minor details wrong but I’m always glad for a sympathetic story on desert plants showing up in desert newspapers. * for approximately the 30th time

I groan every time I see another well-meant attempt to inspire women to pursue science by dressing it up in stereotypical femininity. There’s nothing wrong with pink, and if you want to wear high heels, OK, your choice…but we don’t improve science literacy and appeal by associating it with gender stereotypes. Kate Clancy has an excellent response to some of these errors: “Pseudoscience and stereotyping won’t solve gender inequality in science.”

You Twin Cities folk will have to drive like maniacs to get here in time, but you can do it: I hear the roads are slick as glass so you can just slide all the way here. At 6pm we’re doing another science for the community event, this time with Michael Ceballos talking about biology and biofuels. I’ll be heading over in a little bit to set everything up — I get to be the emcee. It does mean I’ve got a long evening ahead of me, though, and I haven’t had a nap.
