It s been a wonderful run, but with our cast of characters called to perform on many other stages, it s time to take a bow and close the curtain. Happily, all of the posts on the site will remain archived here indefinitely at their original urls, preserved for future reference by the Skeptics Society.In a few days we will announce an exciting new blog project that I think will knock your socks off. I hope you ll join us there (the details will be revealed next week) but today I want to talk about what has been.(continue reading )THIS ARTICLE HAS 13 COMMENTSOrder the book from Shop SkepticIn recent months, we ve heard a number of prominent people (from Michael Shermer to Neil DeGrasse Tyson) say that there s no real difference between the political parties when it comes to science denial. According to this argument, there is  bad thinking and woo on both sides of the political spectrum. To counteract the fact that science deniers like creationists and climate deniers are overwhelmingly Republican, they point to other types of woo like anti-vaxxers, anti-GMOs, anti-frackers, and the like, and claim that these are largely found on the left wing. It turns out, however, that contrary to myth, anti-vaxxers tend to be more right-wing than left-wing (especially among the people who fear government, the large religious crowd that rejects modern medicine, and the home schoolers who don t want to let their kids be vaccinated).For example, in his 2012 book The Republican Brain: The Science of Why they Deny Science—And Reality, Chris Mooney admits that not all examples of science denial are on the right wing. There are certain ideas, such as the  fears of nuclear power, or of scary oil company practices like fracking, that are predominately held by liberals and environmentalists. But there are important differences here. Adherence to pseudoscience and anti-science is not symmetrically distributed between the left and the right. Ideas such as anti-vaxx, anti-nukes, and anti-fracking are not held uniformly by the majority of liberals or progressives, but only a tiny subset, whereas studies show that the ideas of creationism and global climate change denial are virtually universal among American conservatives now.

The story exploded across the internet, especially among the creationist organizations who are once again claiming persecution by scientists. CSUN apparently botched both the hiring of this guy, and now his dismissal, so they ve been sued and this is going to play out badly for them in the courts. But the entire case raises larger issues that are not easily resolved.First, the facts of the case. The plaintiff is Mark H. Armitage, a microscope technician (not a professional biologist). He did some undergrad work in Biology at University of Florida, but didn t graduate. Then he got his B.S. in Education from Jerry Falwell s fundamentalist Liberty University, and his M.S. in Biology (parasitology) from the Institute of Creation Research, an unaccredited fundamentalist organization that  has since left California and closed down its graduate program. As many others have shown, the ICR Master s Degree was a sham, consisting of little more that incompetently done book reports and quote-mining from legitimate scientific literature with a creationist spin, not legitimate scientific research. I ve seen a number of master s theses from there—they are so bad they wouldn t even pass for a freshman book report. Prior to his employment at CSUN, he was employed as a microscope technician at a variety of Christian schools. But he has no Ph.D., no formal training or peer-reviewed published research in the histology he was working on. He s just a humble lab tech on a 2-day a week part-time gig, with no guarantee of employment from one semester to the next. His sole job is to maintain and keep track of the microscopes in a big department with hundreds of them, not to teach courses or do research.

This is an area of the ocean surface in the North Pacific covering between 700,000 square kilometers (270,000 sq mi) to more than 15,000,000 square kilometers (5,800,000 sq mi), larger than the size of Texas. It is composed nearly entirely of plastic trash, fishing nets, and other floating garbage, at least 80% which comes from the land and is non-biodegradable. The denser areas of garbage are so large they can be seen from satellite views.Why is so much garbage concentrated in one area? It all has to do with the oceanic currents that I teach my Oceanography students about. The centers of each portion of the ocean is surrounded by a big circular current called a gyre, which usually runs in a clockwise fashion in the Northern Hemisphere and counterclockwise in the Southern Hemisphere (due to the Coriolis effect). In the North Pacific, a huge gyre completely surrounds the center of the northern ocean, with the warm fast Kuroshio Current coming up from the tropics past Japan, and the cold slow California Current coming down the eastern edge from Alaska, connected by currents (North Equatorial, North Pacific) which travel east or west to connect these in the equator and in the polar regions. This spiraling current tends to accumulate a mound of water in the middle (due to the Ekman spiral effect) that is rather stagnant and does not mix or blend with the boundary currents very well. It is also at a latitude with permanent high-pressure over it, so there s no strong air currents to move it in any particular direction. Consequently, the centers of ocean gyres are slow and stagnant and tend to accumulate stuff that floats into them, and cannot escape. In the North Atlantic, the stagnant center of the gyre is called the Sargasso Sea after the huge floating patches of Sargassum seaweed that floats in the region for decades. There are garbage patches of smaller size in most of the other oceanic gyres as well. But in the North Pacific gyre, what stays put is garbage, the largest such patch in the world.

When polls are conducted about which professions the public considers most trustworthy and useful to society, scientists nearly always come out at or near the top. This poll  by the Pew Research Center of 4006 American adults placed them just below the military, doctors, and teachers in terms of trust and their contribution to society. (To no one s surprise, lawyers were considered the least trustworthy and contributed least to society). This poll by Ipsos of 1018 adults in the UK placed scientists just below doctors and teachers. (Lawyers were not included, so bankers and politicians came out at the bottom in the UK).Historically, this has long been true. Most people appreciate the huge benefit that science brings to society in terms of the technological advances that make our lives longer and better. And despite the stereotypes, apparently most people still regard scientists as objectively seeking the truth, working hard in their labs, and trying to unravel the secrets of the universe. Unfortunately, the most common stereotypical myth, Hollywood s mad scientist out to destroy/ dominate the world is still pervasive as well.

At that time, the normally documentary-filled week that was the channel s biggest draw all year was beginning to show signs of jumping the shark. As I pointed out in previous posts, the deregulation of the airwaves in the late 1980s has led to a steady network decay of once reputable TV channels. When cable TV first expanded into hundreds of speciality channels, they were all dedicated to a core mission, whether it be golf or history or science. As TVTropes.com explains it, all of these deregulated cable networks had to please advertisers, and soon moved into reality shows and sensationalism to attract the core audience of 18-31 year old males that advertisers covet. Discovery Channel used to run almost non-stop documentary footage, and did fine like that for over a decade. As TVTropes.com puts it:The Discovery Channel still shows plenty of actual documentary material, despite having been decaying for almost as long as MTV has. In the late 80s the lineup was mostly serious documentaries, the most famous of which was Wings (no relation to the sitcom except for a focus on aircraft) but which also included classy repackaged BBC imports like Making of a Continent — and once a year there was Shark Week, which was just what you d expect. By the mid-1990s, they showed an obscene amount of home improvement shows and cooking shows aimed at stay-at-home moms (enough to spawn the spin-off Discovery Home Leisure Channel, now Planet Green) and Wings had proven so popular it had been farmed out to its own spin-off, Discovery Wings Channel (now Military Channel). Now, they re being swamped with guys building and/or blowing things up shows in the vein of MythBusters and Monster Garage. And about four different shows about ghost hunters. In 2005, Discovery debuted Cash Cab, a game show that takes place in the back of a cab, leaving one unsure whether it even has a theme beyond non-fiction . It gets weird when you realize that they re knocking some of their own shows off, especially Mythbusters into Smash Lab (with a focus on safety measures) and How It s Made into Some Assembly Required. The latter has almost only done products featured in the former (though How It s Made has been on for just about ten years, so it s hard to find something they haven t done). The Discovery Channel also used to contain a lot of nature, which is where the now-classic Shark Week (which they still air regularly) originated from. But it seems that explosions have taken the place of tigers ripping stuff to pieces. Most of the nature shows have since been relegated to Animal Planet. Amusingly enough, despite the slippage over the years it remains the sole survivor of the educational channels on American cable television. (continue reading )THIS ARTICLE HAS 8 COMMENTSFollowers of the evolution-creation wars in this country have heard about Ray Comfort, a glorified street preacher with limited education (he has no college degree) from New Zealand who runs a ministry out of Bellflower, California, called the Living Waters. In his appearance, he reminds me of Sonny Bono, except he s not as smart. He is very prominent on the internet, with dozens of videos (especially his Way of the Master series) pushing his theology, and especially attacking evolution. His publicity and high visibility have sold lots of his books (most of which are short titles cobbled together by reprinting stuff from the public domain). Together with washed-up actor Kirk Cameron, they have been constant gadflies preaching against science and evolution, and doing anything possible to generate publicity and sales, especially challenging evolutionists to pointless debates.I first saw Comfort in action when he and some of his minions came to stalk the huge crowds gathered to hear Richard Dawkins speak at Caltech for a Skeptic Society event. They mingled about, trying to preach creationism, and handing out their little paperback versions of Darwin s On the Origin of Species. However, this book is no true work of Darwin. Comfort has deliberately edited the text to make it sound favorable to creationism, and added a long introduction that is one debunked creationist trope after another. Keeping with his habit of stalking scientists and secularists, I next saw him at a freethought convention in Orange County, where he snuck in without paying for the conference, and tried to interview some of the speakers. He baited P.Z. Myers into an interview, and P.Z. willingly talked to him, not caring that Comfort would selectively edit the interview to make it sound like P.Z. doubted evolution. Unlike the other big fundamentalist creationist ministers who focus on their own flock, Comfort s approach is as a stalker and gadfly. His mission is to gather video footage that he can take back to his editing room and webmaster, and edit it down to create a gotcha moment and make secularists look foolish.

For a long time, I ve ignored this garbage on the internet, but in recent years it has gotten more and more pervasive, and I ve run into people who believe it. There are whole shows about it on the once-scientific Discovery Channel, and the History Channel as well. Now the chemtrail community circulates their photos and videos among themselves, put hundreds of these videos on YouTube, and on their own sites and forums. But the way the internet works as a giant echo chamber for weird ideas with no peer review, fact checking, or quality control, it s getting impossible to ignore them any more, and it s time to debunk it.The first few times I heard about chemtrails , my reaction was You can t be serious. But the people who spread this are serious. They are generally people who have already accepted the conspiracy theory mindset, where everything that they don t like or don t understand is immediate proof of some big government conspiracy. But there s an even bigger factor at work here: gross science illiteracy. The first thing that pops in my mind reading their strange ideas is Didn t this person learn any science in school? And the fastest rebuttal I give when I run into one of these nuts is: Do you even understand the first thing about our atmosphere? Anything released at 30,000  feet will blow for miles away from where you see it, and has virtually no chance of settling straight down onto the people below, and be so diluted it would have no measurable amount of the chemical by the time it lands. That s why crop-dusting planes must fly barely 30 feet off the ground so their dust won t blow too far away from the crops!

They were angry when Cosmos mentioned Giordano Bruno or scientists who were persecuted by religious extremists during their pursuit of truth. They recoiled in horror at  how often Cosmos reminded us of our cosmic insignificance  compared to the scale of the universe, or from the perspective of geologic time. They raged about the fact that Cosmos spent an entire episode on on evolution, and the topic of evolution came up repeatedly. And lots of pro-business types hated the episode about Clair Patterson s lonely fight against the lead manufacturers, who were invisibly polluting the world and poisoning us all. The climate deniers hated that Cosmos mentioned anthropogenic global warming many times.Nonetheless, most of the reviews for Cosmos were overwhelmingly positive and there s good reason to think that it reached much of its target audience, and inspired a lot of people to think about scientific questions in a way that hasn t  happened since the original Sagan version of Cosmos. I have been rejoicing at the recent resurgence in the media popularity of science and evolution lately, especially after Bill Nye s defeat of Ken Ham, the great response to Neil Shubin s PBS documentary Your Inner Fish, and of course, the huge popularity of Neil DeGrasse Tyson and Cosmos .  Finally, we have several major scientists (Nye, Tyson, Shubin) who are popular in the media, especially on trendy shows like The Daily Show and Colbert Report as well as national news networks like MSNBC and CNN. They are national celebrities for all the right reasons (smart, articulate, telling people the truth about science and the world), rather than being famous because of reality TV or sports or entertainment. They are becoming widely known, and doing a great job of promoting science against the tidal wave of junk science and pseudoscience in the media. There hasn t been such high-profile popularity of scientists since the days of Sagan himself. It s about time! (continue reading )THIS ARTICLE HAS 32 COMMENTSHosted by Skeptic magazine.
