…on climate:

When I was in high-school in England in the 1930s, we learned that continents had been drifting according to the evidence collected by Wegener. It was a great mystery to understand how this happened, but not much doubt that it happened. So it came as a surprise to me later to learn that there had been a consensus against Wegener. If there was a consensus, it was among a small group of experts rather than among the broader public. I think that the situation today with global warming is similar. Among my friends, I do not find much of a consensus. Most of us are sceptical and do not pretend to be experts. My impression is that the experts are deluded because they have been studying the details of climate models for 30 years and they come to believe the models are real. After 30 years they lose the ability to think outside the models. And it is normal for experts in a narrow area to think alike and develop a settled dogma. The dogma is sometimes right and sometimes wrong. In astronomy this happens all the time, and it is great fun to see new observations that prove the old dogmas wrong.

Unfortunately things are different in climate science because the arguments have become heavily politicised. To say that the dogmas are wrong has become politically incorrect. As a result, the media generally exaggerate the degree of consensus and also exaggerate the importance of the questions.

It’s not a new interview, but if anything, it’s even more true now than then. The “consensus” has broken down considerably in the interim.

Climate Skeptics

15 Comments

How and when did you become one?

A lot of interesting responses.

As some note there, to me the biggest deal with the release of the CRU data five years ago wasn’t (just) the duplicity and unscientific behavior revealed in the emails, but the utter crap that was the source code of the computer models. It was clear that it was not done by anyone familiar with computer science, numerical methods, or modeling, and the notion that we should have any confidence whatsoever in their output was societally insane. In terms of Matthews’ paper, I’d put myself somewhere between “lukewarmer” and “moderate skeptic.”

Starting to read through the comments. Here’s just one horror story:

Most of the claims being made by climate change advocates appear to run contrary to basic meteorology. As I’ve been attacked personally and professionally for offering contrary views, I decided to leave the field. I will defend my Atmospheric Science PhD thesis and walk away. It’s become clear to me that it is not possible to undertake independent research in any area that touches upon climate change if you have to make your living as a professional scientist on government grant money or have to rely on getting tenure at a university. The massive group think that I have encountered on this topic has cost me my career, many colleagues and has damaged my reputation among the few people I know in the field. I’m leaving to work in the financial industry. It’s a sad day when you feel that you have to leave a field that you are passionately interested in because you fear that you won’t be able to find a job once your views become widely known. Until free thought is allowed in the climate sciences, I will consider myself a skeptic of catastrophic human induced global warming.

Yup. Totally, totally politicized. It’s not a science any more. Unless you think that Lysenko was a scientist.

Computer Problems

Welp, Windows (7) isn’t happy with the computer upgrade. It keeps running start-up repair, but it never boots.

[Update a while later]

It occurred to me that Windows might not have liked the BIOS settings. So I went into it, and found something under “Advanced” that enabled it for Windows 8 (which I was planning to upgrade to, anyway). When I did that, it told me that the graphics card was incompatible with that setting. So I pulled the card, and am running directly off the mother board. But now when I try to boot, it dumps me into an EFI shell…

[Update a few minutes later]

Well, this doesn’t seem to be an unusual problem…

I tried moving the SATA port of the hard drive, but no joy.

[Evening update]

Well, isn’t this wonderful. I now have a computer that wantonly destroys USB drives.

[Update a minute after I typed that]

OK, it didn’t destroy the drive. It just made it take a couple minutes to recognize it. I guess that’s not quite as bad, but it still isn’t bootable.

[Late-evening update]

OK, now seriously, it is wrecking flash drives. That’s the second one today. I copy a bootable ISO to a drive, it doesn’t boot, then no other computer can even see the drive. That’s two. Today.

“Progressivism”

6 Comments

Telling lies is essential to it.

[Update a few minutes later]

Here’s an excellent example:

In San Francisco, the people who were bemoaning the impending closure of Borderlands admitted sheepishly that they’d voted for the minimum-wage hike. “It’s not something that I thought would affect certain specific small businesses,” one customer said. “I feel sad.”

Yeah, Adam Smith feels sad, too, you dope.

Thick though they may be, you know what those economically illiterate San Francisco book-lovers aren’t? President of the United States of America. But President Obama does precisely the same thing: With Obamacare, he created powerful economic incentives for companies such as Staples to keep part-timers under 25 hours – and to hire part-timers rather than full-time employees – and now he complains when companies respond to those incentives. Naturally, he cites executive pay: “I haven’t looked at Staples stock lately or what the compensation of the CEO is,” he says, but affirms that he is confident that they can afford to run their business the way he wants them to run it.

Let’s apply some English-major math to that question. Ronald Sargent made just under $11 million a year at last report. Staples has about 83,000 employees. That means that if it cut its CEO’s pay to $0.00/annum, Staples would be able to fund about $2.61/week in additional wages or health-care benefits for each of its employees, or schedule them for an additional 22 minutes of work at the federal minimum wage. Which is to say, CEO pay represents a trivial sum — but the expenses imposed by Obamacare are not trivial.

On this issue, President Obama brings all of the honesty and integrity he applied to the question of gay marriage: He’s lying, and he knows he’s lying, and his apologists in the media know he’s lying, and Democratic time-servers and yes-men across the fruited plains know he’s lying. This isn’t about CEO pay – it’s about the economic incentives created by the health-insurance program that in the vernacular bears the president’s name. The president, with the support of congressional Democrats, effectively put a tax on full-time jobs, and on part-time jobs offering 30 hours per week or more. So we’re going to have fewer full-time jobs, and fewer part-time jobs offering 30 hours per week or more. This wasn’t cooked up in the boardroom at Staples – it was cooked up on Capitol Hill, with the eager blessing of Barack Obama. It’s not like they don’t know that there are economic tradeoffs necessitated by Obamacare — they know it, and they also know that, politically speaking, their supporters are cheap dates. Obama ran to the right of Dick Cheney on gay marriage, and it didn’t hurt him with gay voters, who were happy to be reduced to mere instruments of his ambition. The Democrats are betting that part-time workers are similarly easy – or that they’re too dumb to understand the economics at work here, and that they’ll be hypnotized by ritual chants about CEO pay.

I’m hoping that this time, they lose their vile bet.

…the science battle rages.

It would sure be nice if some of these self-identified climate “scientists” would learn some statistics. And stop calling people who understand statistics names like “denier” and “anti-science.”

[Monday-morning update]

Inside the latest global warming scandal:

This kind of thing is going on all over the world. It is one of the reasons why the satellite data (which, however, go back only to 1979) are so important: they have not been corrupted.

Yup.

Soviet-style disinformation dominates the climate “debate”:

Why is it that when a political figure makes a misstatement about a global warming-related issue, which happens many times every day, no government scientific agency or leading university scientist ever corrects them?

For example, all climate modelers correctly label their speculations of future world temperatures as “projections,” meaning that they have no validated forecast skill. Yet politicians, mass media, and the public treat the models as providing temperature forecasts or predictions. Because this misusage is never corrected, politicians cheerily continue to base expensive public policy on it.

Another example: carbon dioxide, as an essential factor in photosynthesis, is the elixir of planetary life, yet politicians dub it a “pollutant.” Similarly, badging the theoretical global warming problem as a “carbon” issue represents scientific illiteracy because it fails to distinguish the element “carbon” from the molecule “carbon dioxide,” and deliberately encourages the public to confuse a colorless, odorless, beneficial gas with soot. Again, climate-alarmist scientists say little or nothing to correct these mistakes.

Many in the public understand that Hendricks’ behavior is typical of politicians everywhere. But most people do not recognize that fraud is also being directly committed in support of this travesty by many of today’s self-appointed “leading climate scientists.” For when they are not directly massaging the data relied upon in their scientific writings, these scientists often report their findings in ways that are intended to deceive the reader into believing that dangerous global warming exists, or will shortly exist. The UN’s climate reports are the magnum opus of this style of operation.

Yes.

The Climate-Modeling Paradigm

6 Comments

How robust is it?

Not very. Certainly nowhere near enough to base policy on it.

I was very impressed by Bakker’s intellectual integrity and courage in tackling this topic in the 11th hour of completing his Ph.D. thesis. I am further impressed by his thesis advisors and committee members for allowing/supporting this. Bakker notes many critical comments from his committee members. I checked the list of committee members, one name jumped out at me – Arthur Petersen – who is a philosopher of science that has written about climate models. I suspect that the criticisms were more focused on strengthening the arguments, rather than ‘alarm’ over an essay that criticizes climate models. Kudos to the KNMI.

I seriously doubt that such a thesis would be possible in an atmospheric/oceanic/climate science department in the U.S. – whether the student would dare to tackle this, whether a faculty member would agree to supervise this, and whether a committee would ‘pass’ the thesis.

Epistemic closure.

The alarming thing about climate alarmism:

In short, climate change is not worse than we thought. Some indicators are worse, but some are better. That doesn’t mean global warming is not a reality or not a problem. It definitely is. But the narrative that the world’s climate is changing from bad to worse is unhelpful alarmism, which prevents us from focusing on smart solutions.

A well-meaning environmentalist might argue that, because climate change is a reality, why not ramp up the rhetoric and focus on the bad news to make sure the public understands its importance. But isn’t that what has been done for the past 20 years? The public has been bombarded with dramatic headlines and apocalyptic photos of climate change and its consequences. Yet despite endless successions of climate summits, carbon emissions continue to rise, especially in rapidly developing countries like India, China and many African nations.

Because all of the hysteria, name calling and outright lies have appropriately destroyed their credibility.
