I love the idea of returning to the Moon, and the idea of going back there to stay I love even more. Having said that, I want to stress it must be done the right way. This has been back in the news lately because Newt Gingrich made a speech about it before his doomed Florida Republican presidential primary run.

What bugs me is that we’re talking about it in context of what Gingrich said; I’d rather we were talking about this on its own merits. There are reasons to go to the Moon, and reasons not to do it Newt’s way… all of which I went over in an interview on CBC radio’s Day 6 show with Brent Bambury that aired Saturday. The interview is archived on their site, and you can listen to it there. I was unusually lucid, IMO, and I think the points made were valid.

I was also interviewed on The Alonya Show, a TV news/opinion program on Russia TV:

[UPDATE: I also did an interview with Globo TV in Brazil that's online as well. The show is in Portugese, but I'm in English with subtitles.]

I want to add to what I said on these two shows. In all this discussion, I wasn’t thinking about the idea of fuel depots. Instead of lobbing big heavy payloads all the way to the Moon with gigantic Saturn V-like rockets, you use smaller rockets to loft tanks of propellant into Earth orbit. Then you can use that smaller rocket to lift the astronauts to orbit, meet up with the tanks, install them, and off to the Moon they go! I don’t know if this saves in money, since it means lots of launches, but it does mean you can get to the Moon without having a huge rocket — one that as yet does not exist.

Anyway, the point is: it’s not fantasy, it’s not (haha) moonbat stuff, and it’s not even science fiction.

Well, check that: it is science fiction. For now. But realistically, we can do this. We have the ability. All we need is the will to do it.

Over the years I have pointed out the fallacious arguments of climate change deniers when they attack legitimate climatologists like James Hansen and Michael Mann. This is, of course, like kicking at a bee hive, and whenever I do the comments section of my posts fill with lots of angry buzzing.

But now, for what I think is the first time, I find myself the target of an attack. And I have to admit, I welcome it: it’s a textbook case of denialist sleight of hand, of distraction, distortion, error, and misdirection.

Stick around for all of this. It’ll be… interesting.

Our story so far

OK, first, here’s the scoop: a few days ago, I wrote a blog post taking apart two intellectually bankrupt climate change denial articles, one in the Wall Street Journal, and the other in the UK’s Daily Mail. Both were claiming that global warming appears to have stopped in the past few years, a claim which is trivially easy to show wrong. In fact, I linked to two articles doing just that: one at Skeptical Science, and another I myself wrote. Finding actual scientists destroying that claim is not hard at all; those two links have many more links therein.

In my post about the WSJ and DM, I included a graph. It pretty clearly shows temperatures rising from 1973 to the present. And this is where the fun begins.

That’s the plot. It’s from a recent, independent study done at Berkeley, and represents actual, measured, data. Just to be clear, those points are from weather stations across the globe, and the method used to collect and analyze those measurements is described by the Berkeley team themselves (PDF). With me so far?

Apparently, William Briggs is not with me. He takes very vigorous exception to the graph in an article he wrote which he titled "Bad Astronomer Does Bad Statistics: That Wall Street Journal Editorial." I encourage you to read it, so that you can assure yourself I am not misrepresenting his arguments in any way.

I found out about this article when I saw a tweet by Dr. Briggs himself. My first thought was: Uh oh. I sure hope I didn’t make a math mistake somewhere in my WSJ post! I better read Briggs’ article and see… So I read it.

My next thought after reading his arguments was then: Ho-hum. So?

The mismeasure of an argument

Basically, Briggs accuses me of not understanding statistics, of not including error bars, of misrepresenting that points in that plot, of not displaying the plot correctly, and so on ad nauseum. His biggest claim: that those points aren’t measurements at all, but estimates.

Here’s the thing: he’s wrong. Those point are in fact measurements, though they are not raw measurements right off the thermometers. They have been processed, averaged, in a scientifically rigorous way to make sure that the statistics derived from them are in fact solid. The Berkeley team describes in detail how that was done (PDF), and does actually call them estimates, but not because they are just guessing, or using some arcane computer model. They are technically estimates, in the sense that any measurement is an estimate, but they are really, really good ones. Greg Laden tears this use of words apart, as well as pretty much everything else Briggs wrote.

Oddly, Briggs then goes on to call them "predictions" for some reason, and that they came from "models", which is just weird. It’s as if he’s trying to use a word choice that raises doubt about the measurements. But again he’s wrong. They really are measurements, not model predictions. At Open Mind, Brigg’s word choice once again is ripped apart. [Note: Briggs has left a comment there, further verifying the fact that his use of words is incorrect.]

This reminds me of one of my favorite skeptic jokes. Question: How many legs does a dog have if you call its tail a leg?

Answer: Four. It doesn’t matter what you call a tail, it’s not a leg.

There are many other places where Briggs makes mistakes that render his arguments null; for example, the error bars (what statisticians usually call "uncertainty") are in fact made available by the Berkeley team, and are small compared to the long-term rise in temperature. For another, Briggs says I should’ve shown the plot going farther into the past, because 1973 was actually a low point. However, that’s completely wrong: it’s actually a high point! As Deep Climate points out here, this actually makes the warming trend lower. So in true contrarian fashion, Briggs is contrary even to himself. It’s bizarre.

So really, there goes Briggs’ argument. His main point is wrong, so we’re done, right?

Well, no. There’s more fun to be had here.

Beside the point

If you read Briggs’ article, you certainly get the impression that because the graph I use is statistically meaningless (so he incorrectly claims), then my whole argument about global warming is wrong.

And this is where I found myself greatly amused, though in a schadenfreude sort of way.

Think of it this way: if my argument hinged on that graph, and I removed it, my argument would have no foundation, correct? It would change the tenor of the entire blog post.

Go look at my article. If you remove that graph from it, what changes? Nothing. My main point — that the WSJ and DM articles are wrong, that we have lots of evidence the Earth is warming up, that 9 of the 10 hottest years on record occurred since the year 2000, that the DM article specifically uses scientific studies and presents them as if they say the exact opposite of what they actually say — still stands.

So even if that graph is wrong and misrepresents what I’m saying — which it does not — it doesn’t matter. In fact, I used that graph as an illustration, to show how we’re warming up. I never intended it to be the basis for the argument I was making, just a way of further showing it. If you read the actual words I wrote, including the links to many, many articles backing up my position, you’ll see that Briggs has not refuted a single actual point I made.

So even if he’s right about that graph, it doesn’t matter. And he’s not right.

But notice what he’s done. He’s taken what is clearly a minor point and blown it up as if it’s my main point. He’s used shady words (predictions, models) to cast aspersions, and to make someone (me!) look bad. Then, by "refuting" this minor issue he can then poison the well, strongly implying that all my arguments are wrong. That’s kind of a big no-no when trying to argue a point.

But it packages well. Watts Up With That, another denialist blog, has run with Briggs’ claims about me as well. He also makes the false claim that warming has stalled, and so on. Note WUWT also says the signers of the WSJ OpEd are "16 scientists", which isn’t true: not all are scientists, and only four have actually published climate science research. And don’t forget about the article the WSJ refused to print talking about the reality of global warming, signed by 255 actual scientists.

Oops.

Denialism’s dark mirror

I will admit the irony of this attack amuses me greatly; Briggs accuses me of many things he himself is doing. That is standard fare from antiscience group: creationists, global warming deniers, and alt-medders, for example, all seem to project their own tactics on the scientists with whom they disagree. Don’t like real medicine? Accuse scientists of being in the pocket of Big Pharma (and forget about the millions being made by quacks on useless "remedies"). Don’t believe in evolution? Accuse scientists of being too dogmatic. Don’t think global warming is real? Accuse scientists of misrepresenting the data.

My favorite irony is that a lot of these global warming denialists take money from fossil fuel interests, but then routinely say to "follow the money", as if it’s the climatologists who are raking in the big bucks from shady think tanks with undisclosed bankrollers. While Briggs points out he gets no money from them, he asks where my money comes from. Think on this, Dr. Briggs; how much money would I make if I suddenly turned coat and said global warming wasn’t real? I’ll guarantee you it would be a lot more than I make now, probably with a couple of zeroes added to the end. So that argument falls a wee bit flat here.

Like all the others.

Of course, given the comments I’ve seen on my blog, on Briggs’ blog, on Watts Up With That, or in any other blog discussing global warming, I know how this will go. You can bring up the major pieces of evidence supporting reality again and again, but the denialists will ignore them and go after phantoms instead. Because if they do acknowledge the actual evidence, they lose.

Over the weekend, two amazingly bad articles were published about climate change. Both were loaded with mistakes, misinterpretations, and outright misinformation, and are simply so factually wrong that they almost read like parodies.

Just so we’re clear here.

The first was in the Wall Street Journal. The article, called No Need to Panic About Global Warming, is a textbook example of misleading prose. It’s laden to bursting with factual errors, but the one that stood out to me most was this whopper: "Perhaps the most inconvenient fact is the lack of global warming for well over 10 years now."

What the what?

That statement, to put it bluntly, is dead wrong. It relies on blatantly misinterpreting long term trends, instead wearing blinders and only looking at year-to-year variations in temperature. The Skeptical Science website destroyed this argument in November 2011, in fact. The OpEd also ignores the fact that nine of the ten hottest years on record all occurred since the year 2000.

The WSJ OpEd makes a lot of hay from having 16 scientists sign it, but of those only 4 are actually climate scientists. And that bragging right is crushed to dust when you find out that the WSJ turned down an article about the reality of global warming that was signed by 255 actual climate scientists. In fact, as Media Matters reports, more of the signers of the WSJ OpEd have ties to oil interests than actually publish peer-reviewed climate research.

Shame on the WSJ for publishing that nonsense.

When I read it, I thought that OpEd was really scraping the bottom of the barrel. But then the Daily Mail chimed in and I discovered that barrel gets a lot deeper. They printed an article by David Rose called Forget global warming — it’s Cycle 25 we need to worry about (and if NASA scientists are right the Thames will be freezing over again).

By "Cycle 25" he’s referring to the solar activity cycle — which I’ll get to in a moment. But first, the most egregiously awful thing about the Mail article is the angle it takes on new results released by The Met Office, the National Weather Service for the UK. The subheadline for the Mail article is "Met Office releases new figures which show no warming in 15 years", which is a bit odd given that the very first two paragraphs of the Met’s press release say:

(more…)

Because I was on the road Wednesday night, I missed the first few hours of reaction to Newt Gingrich’s speech in Florida, when he said he wants to have a permanent station on the Moon "by the end of my second term". It wasn’t until Thursday morning that I opened up my web browser and saw that every blog, every news site, everyone, was talking about it. I must have had dozens of tweets and emails telling me about it and asking my opinion.

So I found a video of the speech and watched it. The only reason I didn’t laugh out loud at the nonsense unfolding from Mr. Gingrich’s mouth was that I already had seen the reaction online.

In Discover Magazine’s Crux blog I wrote a dissection of his speech and why he’s so vastly and profoundly wrong: The Newt-onian Mechanics of Building a Permanent Moon Base. You’ll get all the details there of why I think Gingrich’s plan is the worst possible way to go about trying to go to the Moon: in a hurry, with the wrong source of funding, and maybe because there’s a threat from those dirty communists.

Don’t get me wrong: I want a Moon base. I’ve written about that many times here on the blog, and for my Geek-A-Week card I asked Len Peralta to draw me as Commander Koenig from "Space:1999", for criminy’s sake. I stand second to no one in advocating exploring space, and our own satellite in particular. But it has to be done right, and Gingrich’s plan would be the worst way to do it.

In the post for The Crux I was blunt, but held back my tongue a bit because that isn’t necessarily the venue for me to do otherwise. But here, on my blog, I’ll say this: Gingrich’s words were both transparent and hollow. I knew right away what he was claiming was simply not possible, either financially, technologically, or politically. Take your pick. And it was also clear to me that no matter how you slice it, NASA would get screwed royally if his Moon base plan were implemented, since it would mean billions of dollars moved away from NASA projects to finance this. I started digging deeper to see if my first reaction was wrong, and all I found showed I was righter than I first thought. Every way you try to do it, his plan would destroy NASA. And I’m not exaggerating; the amount of money we’re talking about taking away from NASA projects to fund a base his way would leave everything else in NASA facing cancellation. It’s really that simple.

I was actually pretty stunned that people in Florida would support this idea. Obviously, they would have a vested interest in hearing big ideas about space exploration, but with just a little thought it’s clear that while Gingrich’s idea may be big, it’s only because it’s been stretched out way larger than it can handle. Its density is zero.

On the surface, it seems like Gingrich is a friend of space and science, but don’t be fooled: he’s just as likely to pander to the antiscience base as any other candidate, and his history shows he will attack science when he gets the chance. So while you might be inclined to like the idea of a candidate talking about promoting space exploration under any circumstances, have a care. Because once you get beneath that surface, you might find there’s nothing there.

It’s a truism that whenever I write about the solid fact that the Earth is warming up, that post will get comments that make it clear that denialists — and please read that link before commenting on my use of the word — are like religious zealots, writing the same tired long-debunked arguments that are usually debunked in the very post they’re commenting on.

Still, we press on. The noise machine only wins if they can outshout reality, so it’s important to keep writing about it. Here are five news items about climate change that might help mitigate the nonsense.

1) Last week, I posted the results from studies showing 2011 was the 9th hottest year on record. Forbes online has more information on this. They take a different tack on it, but get the same results I do: the Earth is warming up, and humans are why.

2) Some very welcome news: the National Center for Science Education — who for years have been at the forefront of battling creationists getting their "curriculum" into schools — is adding climate change to their syllabus. At that link they have well-written descriptions of the problem, how to teach about climate change, and how take action against denialism.

You can watch NCSE’s Executive Director, the wonderful Genie Scott (full disclosure: she’s a friend of mine) talk about climate change, and why it’s so important that we tackle this issue politically.

3) One tactic of denialists like Virginia Attorney General Ken Cuccinelli and several Congressmen is to use witch hunts against climate scientists. By filing court orders to get access to emails, for example, they endlessly hound scientists. This serves their purposes quite well: it sets up a chilling effect, for one, making a hostile environment for the scientist; and it sets up doubt in the public’s mind despite there being zero real evidence for it. Michael Mann has suffered this sort of thing many times, despite being cleared of all wrongdoing over and over again.

Now the tables are turned. Scientists have filed a Freedom of Information request to find out who is bankrolling the Global Warming Policy Foundation, a denialist "think tank" with "shadowy funders". In the US, there are groups like this aplenty, and in many cases their funding can be traced to oil companies, the Koch brothers, and so on.

The more people see who actually funds these denialist groups, the better. Once it became public that it was the tobacco industry pumping so many lies into the media about cigarettes the tide turned, and these global warming denialist groups are literally using the same tactics. And hey, the Heartland Institute, which bills itself as libertarian, also has ties to tobacco at the same time it funds New Zealand climate denial groups, too.

4) Apropos of that, some good news in the fight: the Climate Science Legal Defense Fund — which helps raise money for beleagured scientists under attack by denialists — has a new home: Public Employees for Environmental Responsibility (PEER). PEER will provide sponsorship and logistical support for the fund. Money raised goes to help defray the costs of legal fees for scientists who are the subjects of the above-mentioned witch hunts. The CSLDF also helps educate scientists about their rights, recruits lawyers to help out, and serves as an information database related to legal actions against scientists.

Wanna help? Donate to the fund here.

5) … and apropos of that, it’s nice to see scientists fighting back, too.

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.

By the time you read this, you have already heard or discovered that Mozilla, reddit, Wikipedia, and many others sites are going dark today to raise awareness about Congress’s highly regressive internet blocking legislation. The House’s version, SOPA, is making headlines, but the Senate version, PIPA, is pretty much the same.

I am not blacked out for two reasons. Since I am hosted on Discover’s site, I cannot take the whole thing down, and it would not be appropriate for me to ask. But also, simply blacking out raises awareness but doesn’t give information. I’m all about making sure people get good info, so below is a list of links where you’ll find why so many people hate this legislation so much.

- Google (!)

- reddit (they also have this page with many links to help you take action)

- Adam Savage at Popular Mechanics

- Forbes (though it’s clearly not correct to say SOPA is dead, and I no longer trust Obama will do as he says after signing the NDAA)

- Mashable

- Wil Wheaton

And I’ll note: I have a friend in the film industry whom I like and respect very much. She and I talked about this; she had a film pirated so much she made no money on it, and couldn’t pursue the pirates because they were overseas. She is right that we need a better way to find and prosecute (or at least stop) that sort of thing, and as far as I can tell SOPA would in fact stop what happened to her. Unfortunately, it does far, far more. I do not and cannot trust this government — or any that may follow — to use this kind of power judiciously. The links above will show you why.

I am against these bills, and I urge you to contact your Congresscritters. I already know my Representative, Jared Polis, is against PIPA, since he’s been fighting it nonstop. Find out what yours thinks, and act appropriately.

[Update: I had inadvertently switched which bill went with which part of Congress, and it's now fixed. My apologies.]
