2011: The 9th hottest year on record

If anyone tells you the Earth isn’t warming up…

… tell them they’re full of it.

2011 was the ninth hottest year on record, and those records go back 130 years.

And then they might say, well, sure, but that could be coincidence. Then you look them straight in the eye, and you say:

Nine of the ten hottest years on record have been since 2000.

The map above shows changes from average (where the average is from 1951 to 1980). You see clearly that temperatures over land have increased almost universally. Most of the ocean temperatures have gone up as well; the one big cooler region in the eastern Pacific is due to the La Niña last year, so it’s a temporary effect. Even with La Niña dropping temperatures, the overall effect is an increase in temperature. I’ll note that sunspot numbers were low last year as well, which (if anything) should result in a (very) slight cooling effect too.

Climate change deniers will gnash and froth — I expect the comments to this post to reflect that, as they always do — but the bottom line is this. The Earth is getting hotter. Human beings are at least partly to blame, and the evidence has piled up that we are mostly to blame. Not the Sun, not cosmic rays, not orbital oscillations. Humans.

As I’ve said before, here are the facts:

The Earth is warming up. The rate of warming has increased in the past century or so. This corresponds to the time of the Industrial Revolution, when we started dumping greenhouse gases into the atmosphere. Greenhouse gases warm the planet (hence the name) — if they didn’t we’d have an average temperature below the freezing point of water. Carbon dioxide is a greenhouse gas which is dumped into the atmosphere by humans to the tune of 30 billion tons per year, 100 times the amount from volcanoes. And finally, approximately 97% of climatologists who actually study climate agree that global warming is real, and caused by humans.

Given the vast amount of evidence supporting all this, denying it is fantasy. Again, that won’t stop deniers: they will obfuscate, blow smoke, and nitpick details to make them seem important. But what they’re doing is fiddling while Earth burns.

Skeptic Zone interview: Doooooomsday

My old pal Richard Saunders from Australia skyped me up (which sounds dirtier than it is) and we chatted about doomsday prophecies — 2012, mostly, but also all the endless failed predictions of years gone by — for his podcast The Skeptic Zone (you can grab the MP3 here too). It’s always fun to chat with Richard. We’ve known each other a long time (as you can tell by the picture of the two of us there — click to southernhemispherenate) and I think that helps.

I also gush a bit about the live stuff I’m doing with Fraser Cain on Google+, including astronomy news roundups every Thursday, and live video telescope viewing via webcams. My part starts at about 12:30 in, but you should listen to the whole thing. It’s a good podcast, and he has an adorable accent.

No, SETI has not detected an alien signal from a Kepler planet

Last night, I started getting emails and tweets asking about a possible detection of a radio signal coming from two of the newly-discovered planets orbiting other stars.

Cutting to the chase: yes, a signal has been seen, but no, it’s not coming from some alien civilization. It’s almost certainly something much closer, like a satellite interfering with the observation.

So what’s the deal?


You talkin’ to me?

The Search For Extraterrestrial Intelligence (SETI) is a privately-funded group of scientists and engineers who are trying* an ongoing effort to figure out ways to detect signals from space that could be coming from other intelligences: aliens. They focus (haha) mostly on radio signals, since it’s very easy to send radio waves across the vast light years separating stars, it’s easy to detect radio waves (so primitive life like us can pick up the call), and it’s easy to encode information that way. Heck, we’ve been broadcasting coded radio waves for over a century now!

Currently, no unambiguous alien "Hello there!" has been detected. The sky is big, there are a lot of stars out there, and the radio spectrum is really wide, too. Think of how many radio stations there are on a typical radio dial from top to bottom; now divide that up into a billion tiny slices and try to find the one that’s playing the song you want to hear. It’s something of a painstaking process.

Recently, astronomers came up with a clever idea: the Kepler space mission is finding tons of planets orbiting other stars. It may find an Earth-like planet orbiting a Sun-like star at just the right distance to allow life to evolve, though no such planet has been found just yet. Still, why look all over the sky when we know where there are lots of planets?


Can’t stop the signal

So a search targeting those stars with planets has been set up. And that’s where our story picks up: using the ginormous 100 meter Green Bank Telescope, astronomers from UC Berkeley found what look like artificial signals when observing two different stars. The stars are called Kepler Object of Interest 812 and 817 (or just KOI 812 and 817 for short). Here’s an example of a signal they found from KOI 817:

Stop antivaxxers. Now.

There are times when reality is so obvious, so clear, so rock-solid 100% amazingly in-your-face incontrovertible, that it is beyond belief that anyone could deny it.

And yet, antivaccination groups exist.

Let me be very, very clear: they are wrong. Vaccines save lives. Vaccines save millions of lives. And not just directly, like they did by wiping out smallpox, a scourge that killed hundreds of millions of people. But also, through herd immunity, vaccines save infants too young to be vaccinated, the elderly with weak immune systems, and people whose immune systems are compromised due to chemotherapy, genetic issues, or because they are taking immunosuppressants for other illnesses (like arthritis).

Vaccines don’t cause autism. Vaccines don’t contain dangerous levels of mercury. Vaccines don’t contain fetal tissue. Each of these – and many, many more — is misinformation spread by antivaxxers, statements that are easily proven wrong (like, in order, here, here, and here). But many antivaxxers continue to use them.

What does that say about their willingness to tell the truth?

Yesterday, in Australia, one of the most vocal antivaxxers alive, Meryl Dorey of the grossly misnamed Australian Vaccination Network (AVN), spoke at the Woodford Folk Festival about her beliefs. However, she didn’t get quite the chance she had hoped for. Once the news got out that she was invited to the festival, the group Stop AVN went into action. A protest cry went up, and the venue was changed from her speaking solo, to her participating in a panel with a series of experts — actual, real experts — on vaccines. As I write this, I have a window open on Twitter, and I’m watching the tweets using the hashtag #StopAVN flow by. It’s a thing of beauty. Dorey’s arguments are being destroyed, 140 characters at a time.

The bottom line, repeated over and over again: Vaccinations save lives. That statement of fact is so simple, so powerful, that Stop AVN put it on a banner and had it flown behind a plane at the festival.

Wonderful! My congratulations to my friends Down Under for this impressive campaign.

But we here in America cannot rest easy. We have antivaxxers here; loud, wealthy, ones, who won’t hesitate to spread the same kind of misinformation; dangerous misinformation that poses a serious health threat.

The National Vaccine Information Center is one such group. They have a long history of antivax rhetoric, remarkable only in its breathtaking inaccuracy, and their ability to get it into the mainstream. And they’re at it again: they’ve put an ad on ABC’s digital 5000 square foot screen in Times Square in New York City, a place that will be packed with people celebrating the new year. To top it all off, Jenny McCarthy — who dispenses incredibly dangerous and incredibly wrong advice about vaccinations and other health safety issues — is slated to be a guest on ABC’s New Year’s Rocking Eve with Dick Clark… and she has stated she plans to promote her dangerous nonsense on the show.

Skepchick has an excellent post about this. My friend Jamie Bernstein has started a petition on change.org to get the ad taken down. I signed it.

Again, let me be clear: these antivax groups pose a public health threat. If you don’t believe me, then read this account by someone who knows.

And if you wonder why I feel so strongly about this, then I suggest you steel yourself — seriously — and read this account written by the parents of Dana McCaffery, who lost her life to pertussis when she was four weeks old. She was too young to be vaccinated. Because vaccine rates were so low in her area, pertussis had a place to grow. She was infected, and she died.

You want to know why I feel so strongly? This is why. She is why.

Talk to your board-certified doctor about vaccines. Find out what you might need — being an adult doesn’t mean you’re exempt from childhood vaccines; you may need a booster — and if your doctor approves, then do what needs to be done.

The solution against the antivaxxers is to make sure their misinformation is countered by facts. It’s one of life’s great ironies that vaccines have helped these people live as long as they have to spread their nonsense about vaccines. We can speak up to stop them… and at the same time get vaccinated to make sure that they — that everyone – gets a chance to be wrong for a long, long time.

Blastr: Invasion Earth!

I watched "Battle: Los Angeles" recently, a movie about aliens invading the Earth. It wasn’t terrible, and it wasn’t great. It was watchable, and worked sufficiently well in lowering our supply of popcorn at Chez BA.

But like every alien invasion movie I see, there’s one small, really eensy-weensy problem: the reason they give for the invasion itself was dumb. [SPOILER] They came to steal our water? And use it for fuel? Say WHA?

Ignoring the silly idea of using water for fuel — that’s got physics exactly backwards, since you get energy out of combining oxygen and hydrogen to make water, and it takes energy to crack them apart — there’s an even bigger problem…

… which I won’t tell you here, because I go into all sorts of detail in my latest Blastr article, 6 Reasons Why Aliens Would NEVER Invade Earth. Mind you, I’m not talking about aliens just coming here to shoot the breeze, but aliens coming here to shoot us. It’s hard to think of a good reason they’d do so, and certainly the reasons given in pretty much every movie don’t make sense. And I have a real problem with just how bad aliens are at taking over. Wiping us out should be pretty easy; heck, I wrote a whole other Blastr article about that, too.

So head on over there and give it a read. Agree, disagree? Leave a comment there, too. But if you disagree, be nice: I’m way better at wiping out life on Earth than any Hollywood alien could hope to be.

The $37.6 Million Dollar Fine HE Doesn’t Want You To Know About

If schadenfreude made a noise, then you’d be hearing it pretty loudly from me right now: Kevin Trudeau — a convicted credit card fraud, and a man who made tens if not hundreds of millions of dollars by telling people he could cure their cancer using, get this, coral calcium — has lost his appeal to the federal court, and must pay $37.6 million dollars in fines.

Trudeau, who shilled this false cancer cure as a diet supplement, was ordered by a federal judge in 2008 to stop making and airing infomercials about it. I wrote about this at the time, but I kept seeing those evil infomercials on TV. I wondered about this, but now I understand: Trudeau was trying to sidestep the order by selling books about this false cure, not the supplements directly. And, he kept buying up those ad spots while appealing the order. But on November 29th of this year, the appeals court said "nope".

As the court papers say:

The protections, unfortunately, were too weak: Trudeau aired infomercials in violation of the order at least 32,000 times. He should not now be surprised that he must pay for the loss he caused. At a minimum, it was easily within the district court’s discretion to conclude that he should. And $37.6 million correctly measures the loss. The figure is conservative — it only considers sales from the 800-number, not sales in bookstores carrying his "As Seen on TV" titles…

Wow, so he only violated a court order 32,000 times. But wait, there’s more! Apparently, there’s not a lot of real info in those books; they just funnel people to a web site urging them to spend hundreds of dollars for the products he sells. So how much money do you think he really made?

The court also instituted a $2 million bond in case he tries to make more infomercials. It doesn’t stop him from placing ads or writing books, just from bilking people using those long-form late night infomercials:

“Alternative” cancer clinic threatens to sue high school blogger

Everyone has been touched by cancer in one way or another. If you haven’t had it yourself, the odds are extremely high you know someone who has, and who has died from it. I’ve lost loved ones to cancer, and it’s awful; it can take years filled with tests, hope, lack of hope, expensive therapy… and in the end the odds are what they are. It all makes for desperate times for those involved, with an emotional distress level that is beyond my ability to describe.

There are people out there who claim they can cure cancer, or have therapies that can mediate it. Some of these people are simply con artists, ready to swoop in as soon as they smell blood in the water, vermin that they are. Others are honest but wrong, thinking they have stumbled on some therapy that no one else has found. However, time and again, when these alternative methods are tested rigorously using controlled, properly done studies, they are shown not to work. In general this does not stop people from making the claims, however.

In Houston, Texas, is a man named Stanislaw Burzynski. He claims he has a method for treating cancer. He calls it antineoplaston therapy. However, according to the National Cancer Institute, “No randomized, controlled trials showing the effectiveness of antineoplastons have been published in peer-reviewed scientific journals.” That’s a bad sign. Furthermore, the FDA has not approved of antineoplaston therapy for use. Also telling is that “… other investigators have not been able to obtain the same results reported by Dr. Burzynski and his team”. Yet, despite this, Burzynski charges hundreds of thousands of dollars for people to get his therapy — though he has to say they’re participating in research trials, since the FDA won’t allow him to use his ideas as an actual treatment.

Those are red flags, to be sure.
