Global Warming Deniers Get a Double-Dose of Pwnage

Posted by mattusmaximus on November 17, 2009

I’ve blogged here before about various claims made & tactics used by climate science deniers (I refuse to call them “skeptics” because they are not guided by evidence, merely ideology), but what I have to share in this post is truly damning stuff.  One of the things which is really interesting is what happens when a group of pseudoscientific ideologues (like global warming deniers) gets caught red-handed playing fast & loose with the facts…

Exhibit A: Statisticians Confirm Reality of Global Warming in Blinded Tests

Recently, one of the claims making the rounds has been that, contrary to the consensus within the climate science community, the Earth is actually entering a period of global cooling – this claim is patently fallacious, and anyone who has a basic understanding of statistics knows it.  But what happened recently, as reported in a widely-circulated AP story, really slams the door shut on this bogus claim: the temperature data for the planet was analyzed by a series of independent statisticians, all of whom found a warming (not a cooling) trend in the data.  And here’s the kicker: these statisticians didn’t know what the data were – in other words, the examination of the Earth’s temperature data was a blinded test!

Have you heard that the world is now cooling instead of warming? You may have seen some news reports on the Internet or heard about it from a provocative new book. Only one problem: It’s not true, according to an analysis of the numbers done by several independent statisticians for The Associated Press.

The case that the Earth might be cooling partly stems from recent weather. Last year was cooler than previous years. It’s been a while since the super-hot years of 1998 and 2005. So is this a longer climate trend or just weather’s normal ups and downs?

In a blind test, the AP gave temperature data to four independent statisticians and asked them to look for trends, without telling them what the numbers represented. The experts found no true temperature declines over time.

“If you look at the data and sort of cherry-pick a micro-trend within a bigger trend, that technique is particularly suspect,” said John Grego, a professor of statistics at the University of South Carolina.

This result puts paid to the oft-repeated claim by GW-deniers that there is a cooling trend in the data.  Of course, the only reason why these pseudoscientists were able to get away with their false claims for so long was because they, as professor Grego said, have been cherry-picking the data and presenting it incomplete & out-of-context in order to give the impression that the Earth is cooling.  But, as we’ve seen, once the experimenter & statistician bias is removed from the analysis, which is the whole purpose of doing blinded tests, a very real and consistent warming trend is revealed.

But it gets even worse for the GW-deniers…

Yes, We Really DID Send Humans to the Moon – LRO Images Apollo 11 Landing Site

Posted by mattusmaximus on November 16, 2009

Over the years you’ve no doubt heard claims that the Apollo Moon landings were an elaborate government hoax. Of course, this is one of the silliest conspiracy theory claims I’ve ever heard, but then once people start to venture down the rabbit-hole of conspiracy mongering I’m of the opinion that logic & reason go right out the window.  In any case, ever since these CT-lunatics (pardon the pun ;) ) have started making their hoax claims a decade ago, one of their most oft-repeated mantras is: “If we really did send humans to the Moon, then why doesn’t NASA show us pictures of the landing sites?”

Well, here you go, an image of the Apollo 11 landing site as seen by the Lunar Reconnaissance Orbiter (LRO)

onegiantleap

A detailed description of this photo is given over at the Bad Astronomy blog:

We’ve seen it before, but this time LRO is in its 50 km mapping orbit, so the resolution on this image is far higher — about 50 or so centimeters (20 inches). In this image, the tracks made by Armstrong and Buzz Aldrin as they scampered on the Moon for 2 hours and 31 minutes are obvious. You can even see the lander footpads, each just less than a meter (a bit over a yard) across.

The bright spots south of (below) the lander are various scientific packages they installed, including the Lunar Ranging Retro Reflector and the Passive Seismic Experiment. If I’ve got the scale right, the faint dark trail going to the upper left is where they put the TV camera. Somewhere between that and the lander is the flag. The Sun was shining straight down in this image, so the flag isn’t visible.

Physics of Karate – No Woo Required

Posted by mattusmaximus on November 14, 2009

I’ve practiced martial arts of various styles for 20 years, and in all that time I’ve heard a number of very strange & woo-filled explanations for why people can accomplish the physical feats they can.  One such example is breaking wooden boards with the bare hands & feet – often people provide an explanation by referencing so-called “chi, ki, or qigong energy”. The whole concept of chi is more of a philosophical concept than anything else, and it is little more than a “dragon-in-the-garage” (an untestable notion that cannot be verified through scientific means).

karate chop

Well, I’m here to tell you that such physical feats as board breaking can be performed & explained simply by referencing the known laws of physics – no woo required.  Take a look at the video of me performing such a break with five pine boards at once…

How do I accomplish this feat?  Here’s how: I hit the boards really hard – the question is how do I generate such a large force of impact?  Read on…

Creationists Ray Comfort & Kirk Cameron “Promote” Darwin’s ‘Origin of Species’

Posted by mattusmaximus on November 10, 2009

In the latest installment of the lame attempts by creationists to stifle and distort the teaching of evolution, Christian evangelists Ray Comfort & Kirk Cameron (yes, that guy on Growing Pains) are giving away copies of Charles Darwin’s Origin of Species. Except they’re doing that thing that too many creationists love to do… they screw up science in an effort to promote their own narrow religious ideology. Specifically, Comfort’s Christian ministry – Living Waters – has begun a new program called “Origin Into Schools” where they are distributing free copies of a special reprinted edition of Darwin’s work, complete with an introduction by Ray Comfort himself.

The Secular Student Alliance is all over this, so allow me to reference their page on the matter:

Living Waters, the evangelical Christian ministry of Ray Comfort (Banana Man) and Kirk Cameron (sitcom star of Growing Pains), is on a mission to distribute 100,000 copies of a reprinted version of Darwin’s On the Origin of Species, with an introduction by Comfort attempting to refute Darwin’s theories.  You can see Comfort’s explanation of the project on their website.  Or, you can download and read the Introduction in PDF form.

The highlights of the introduction, according to Kirk Cameron (who explains the project on YouTube), include “a timeline of Darwin’s life, Adolf Hitler’s undeniable connection with the theory, Dariwn’s racism, his disdain for women and Darwin’s thoughts on the existence of God.”  The introduction also “lists the theory’s many hoaxes.”

David Waters’ column “Origin of the Specious” in the Washington Post,  sums up the project quite nicely.

Chicago Skepticamp Needs Speakers!

Posted by mattusmaximus on November 10, 2009

I wanted to let everyone know about an effort I’m helping to organize to bring a Skepticamp event to the Chicago-area on March 6th, 2010 – we’re calling it Skepchicamp…

We are currently in the early stages of organizing the conference, and one of the things we need most right now are speakers.  Please read our latest press release for more information on this, and consider getting involved or at least passing along the news:

Skepchicamp looking for speakers

Skepchicamp, an informal skeptical convention scheduled for March 6, is looking for speakers.  Speakers are welcome to give a 15 minutes speech on any topic related to skepticism, followed by five minute of questions and answers.  In additions to speeches, demonstrations, magic shows, and panel discussions will also be considered.  While speakers are encouraged to focus on women in skepticism or women in science, it is not a requirement.  People interested in speaking should e-mail don@skepchicamp.com

Speakers currently scheduled to appear include Hemant Mehta, creator of the Friendly Atheist blog and author of “I Sold My Soul on Ebay” and Skepchick bloggers Bug Girl, Elyse Anders, and Jen Myers.

Skepchicamp  is an informal convention with the goal of promoting skeptical thinking in the Chicago area.  Unlike formal conventions, everyone who attends Skepchicamp is expected to participate in some way.  That can include giving a speech, serving food, helping to set up a room, or donating money.   The goal is to create a laid-back event driven by the participants.

Skeptics believe that everything should be examined with scientific rigor, and generally choose to suspend belief (or agree to append beliefs) based on the availability of adequate evidence. Many skeptics do not believe in the supernatural simply have not seen enough credible evidence to convince us that they exist. They are not curmudgeons who dislike ghost stories. There are, however, many things that skeptics do believe in. Like love, the power of beauty, art, friendship, humor, and sports because we know these things to be true. Nothing falsifiable is exempt from scrutiny.

Happy Carl Sagan Day!

Posted by mattusmaximus on November 9, 2009

Happy Carl Sagan Day… or, to be more accurate, belated Carl Sagan Day :)

November 7th is the birthday of that great communicator of science & skepticism, Carl Sagan.  In a time when many of his fellow scientists were loath to communicate directly with the public, Sagan was a unique link between the scientific community and the general populace.  He communicated the power, joy, and importance of science to us through lectures, books, and television.  In particular, I think I can honestly say that an entire generation of scientists were inspired by Carl Sagan’s book and television series Cosmos (which aired in 1980) – I count myself among them. Were it not for the inspiration provided to me in my teenage years by my beat-up copy of the book Cosmos, I may have never pursued a career in science…

The unforgettable introduction to Cosmos: The Shores of the Cosmic Ocean is available on Youtube…

And a recently auto-tuned remix of Carl Sagan’s dialog from Cosmos, called “A Glorious Dawn (featuring Stephen Hawking)”, is also available on Youtube.  Check it out…

**Note: You can download your own copy of “A Glorious Dawn” from its creator’s website – SymphonyofScience.com
- where there are many other cool videos & music files available.

Jay Leno Sticks It to Sylvia Browne — On Live TV

Posted by mattusmaximus on November 5, 2009

On Tuesday, Nov. 3rd, psychic Sylvia Browne made a surprise guest appearance on The Jay Leno Show. This is very surprising, seeing as how Leno is a definite skeptic when it comes to psychics & their woo (he coined the now famous phrase “Why don’t you ever see this headline: ‘Psychic Wins Lottery‘?”).  So why was Browne there in the first place?

What happened is that his show has a segment called Earn Your Plug, whereby celebrities who wish to have their TV show or movie plugged have to do something on the show to merit the advertising.  Well, last night the celebs were Katie Featherston and Micah Sloat of the movie “Paranormal Activity”, and for the Earn Your Plug segment they decided to surprise Leno by having Sylvia Browne give him a reading.  See for yourself how it went…

Jay Leno vs. Sylvia Browne

Right off the bat, Leno was completely blindsided by the fact that a psychic like Browne was even on his show.  Notice how he makes the crack at the beginning of the reading about replacing some employees in the near future; something tells me that this is one prediction which is likely to come true.  Had he known that Featherston & Sloat had wanted to bring Browne onto the show, Leno would have likely stopped it from happening.

In addition, I want to point something else out that Leno did – he was openly, though playfully (his show is about entertainment, after all), skeptical of what Browne was attempting to do.  Whenever she made a claim, rather than allow her to prattle on and on with all manner of nonsensical “predictions” (often known as cold reading), he would stop her and challenge her on specific points.  It is also worth noting how she reacted to Leno not simply believing what she said or at least playing along with her: she got angry with him.  She didn’t get screaming mad, but watching her demeanor and body language speaks volumes about how upset she was that he even dared to question her supposed divine prowess (she did claim, after all, that her “abilities” were “from God”).  Essentially, she was doing little more than making a blatant argument from authority in this regard, and it was painfully (for her) obvious that Leno wasn’t having any of it.

I think a good example was this exchange:

Browne: “Do you know how many people over the years have told me that I’m wrong about something, but came back later to tell me that I was right?”

Leno: “No. How many?”

In the end, I think that while it was a negative that a psychic scumbag like Sylvia Browne even got onto Leno’s show in the first place, Leno himself turned it into a more positive experience by not treating her seriously & acting openly skeptical and asking questions.  The result was, in my opinion, that by the end of the reading – which was mercifully short – the vast majority of the audience was laughing at Ms. Browne and not with her.  And if there’s anyone who deserves to be laughed at, it is Sylvia Browne and her ilk.

Good move, Jay, for educating people on how to deal with such supernatural claims.  Johnny Carson would be proud of you :)

Remember, Remember the 5th of November: Anonymous Continues Protests of Scientology

Posted by mattusmaximus on November 3, 2009

I just wanted to pass along a little info to you all concerning some upcoming protests this Thursday, November 5th, of the Church of Scientology by the group called Anonymous. An image that has become synonymous with the Anonymous protests is the mask of Guy Fawkes, who is recognized for his involvement in the infamous Gunpowder Plot on the 5th of November every year in the United Kingdom.

Guy Fawkes

Many Anonymous protesters wear the Guy Fawkes mask when peacefully picketing CoS centers & passing out information to passersby about the cultish practices of the Church.  Contrary to CoS propaganda, these are peaceful protests which are designed to get out the truth about the Church and its practices; in no way, shape, or form do I, nor does Anonymous, encourage or condone any kind of violent or illegal action against the Church of Scientology!

So what’s with the Anonymous wearing the Guy Fawkes masks?  The answer is twofold: they do this not only to make a statement but also to protect themselves from the Scientologists who would attempt to ID them & label them as “suppressive persons” (SPs) and therefore target them for harassment. Believe me, even though I’ve never participated in an Anonymous event nor have I ever had a run-in with the CoS, from what I understand you do not want to be on that SP hit list.  So if you’re going to participate in one of these events, protect yourself (and others) and conceal your identity.

Anonymous tends to get its message out via the Internet, specifically through using online video.  For example, below are two Youtube videos: one of the first videos ever released by Anonymous back in January 2008…

… and a very recent video about the upcoming worldwide protests of the Church of Scientology on November 5th…

If you want more information regarding these protests, then check out the WhyWeProtest.net website.  For more information on Scientology in general, it’s hard to find a better site than Xenu.net, also known as Operation Clambake.  Spread the word.

Knowledge Is Free.

Skeptic Zone Podcast: “Darwin’s Bulldogs” Panel from Dragon*Con

Posted by mattusmaximus on November 2, 2009

I wanted to pass along the audio of a panel discussion I moderated at Dragon*Con this past Labor Day weekend – the title of the panel was “Darwin’s Bulldogs: Teachers on the Front Lines” and it was about creationism & how to deal with it in public schools.  I proposed the panel, and I was joined by Kylie Sturgess of the Podblack Cat blog, C. Kevin Barrett (a writer and biological anthropologist), Martin Bridgstock of Griffith University and author of the forthcoming book ‘Beyond Belief: Skepticism, Science and the Paranormal‘, Barbara Drescher, a cognitive psychologist and lecturer at California State University, Northridge, and our guest of honor, Dr. Eugenie Scott of the National Center for Science Education.

The audio file is available at the Skeptic Zone podcast website; it’s their October 30th recording.  Hat tip to Kylie Sturgess at Podblack Cat for passing this along to me :)

A Good Halloween Lesson: Randi’s “Secrets of the Psychics”

Posted by mattusmaximus on October 29, 2009

Again, in the spirit of Halloween and skepticism, I want to share with you all what is likely one of the best videos ever: James Randi’s “Secrets of the Psychics”. I often show this video to my students around this time of year, when many of them are (consciously or not) thinking about psychics & various paranormal phenomena.

If you’ve never seen the entire video, I strongly encourage you to watch it all.  In addition, if you really want to get a good look into real paranormal investigation, take some time to check out one of the best skeptical books on the topic: James Randi’s “Flim-Flam! Psychics, ESP, Unicorns, and Other Delusions” :)
