Climate Evangelists

How they’re taking over your weather forecasts.

Pretty sure that meteorologists in general aren’t part of the BS 97%, though. Interesting comment that weather is the only thing keeping local news alive. It’s the only reason I generally turn it on. I haven’t noticed and of the LA weathercasters talking about climate so far, though, fortunately.

Gavin Schmidt

He attempts to discredit Judith Curry, and you’ll never guess what happens next!

There is one wonderful thing about Gavin’s argument, and one even more wonderful thing.

The wonderful thing is that he is arguing that Dr. Curry is wrong about the models being tuned to the actual data during the period because the models are so wrong (!).

The models were not tuned to consistency with the period of interest as shown by the fact that – the models are not consistent with the period of interest. Gavin points out that the models range all over the map, when you look at the 5% – 95% range of trends. He’s right, the models do not cluster tightly around the observations, and they should, if they were modeling the climate well.

Here’s the even more wonderful thing. If you read the relevant portions of the IPCC reports, looking for the comparison of observations to model projections, each is a masterpiece of obfuscation on this same point. You never see a clean, clear, understandable presentation of the models-to-actuals comparison. But look at those histograms above, direct from the hand of Gavin. It’s the clearest presentation I’ve ever run across that the models run hot. Thank you, Gavin.

Yes, thank you.

Mindless Eating

and mindless research:

Problems with p-hacking are by no means exclusive to Wansink. Many scientists receive only cursory training in statistics, and even that training is sometimes dubious. This is disconcerting, because statistics provide the backbone of pretty much any research looking at humans, as well as a lot of research that doesn’t. If a researcher is trying to tell whether changing something (like the story someone reads in a psychology experiment, or the drug someone takes in a pharmaceutical trial) causes different outcomes, they need statistics. If they want to detect a difference between groups, they need statistics. And if they want to tease out whether one thing could cause another, they need statistics.

The replication crisis in psychology has been drawing attention to this and other problems in the field. But problems with statistics extends far beyond just psychology, and the conversation about open science hasn’t reached everyone yet. Nicholas Brown, one of the researchers scrutinizing Wansink’s research output, told Ars that “people who work in fields that are kind of on the periphery of social psychology, like sports psychology, business studies, consumer psychology… have told me that most of their colleagues aren’t even aware there’s a problem yet.”

I think the hockey stick episode shows that this is a problem with climate research as well.

The point of peer review has always been for fellow scientists to judge whether a paper is of reasonable quality; reviewers aren’t expected to perform an independent analysis of the data.

“Historically, we have not asked peer reviewers to check the statistics,” Brown says. “Perhaps if they were [expected to], they’d be asking for the data set more often.” In fact, without open data—something that’s historically been hit-or-miss—it would be impossible for peer reviewers to validate any numbers.

Peer review is often taken to be a seal of approval on research, but it’s actually more like a small or large quality boost, depending on the reviewers and scientific journal in question. “In general, it still has a good influence on the quality of the literature,” van der Zee said to Ars. But “it’s a wildly human process, and it is extremely capricious,” Heathers points out.

There’s also the question of what’s actually feasible for people. Peer review is unpaid work, Kirschner emphasizes, usually done by researchers on top of their existing heavy workloads, often outside of work hours. That often makes devoting the time and effort needed to catch dodgy statistics impossible. But Heathers and van der Zee both point to a possible generational difference: with better tools and a new wave of scientists who aren’t being asked to change long-held habits, better peer reviews could conceivably start to emerge. Although if change is going to happen, it’s going to be slow; as Heathers points out, “academia can be glacial.”

“Peer review” is worse than useless at this point, I think. And it’s often wielded as a cudgel against dissidents of the climate religion.

Science As Religion

Nice to see things like this at Slate. Everyone who “marched” yesterday should read it. Didn’t like the “science deniers” reference in last graf, though.

[Tuesday-morning update]

The “March For Science” failed, as demonstrated by its own signs:

Time to brush up on your social science, Science Guy. You too, Astrophysicist Dr. DeGrasse Tyson. You too, all ye faithful March for Science marchers, all ye believers in Truth, Science, and the Objective Way. Beware your own version of science denial. The idea has not developed “somehow”, “along the way”, that belief is informed by more than just what science says. Modern humans have always interpreted the facts based on deep values and meanings, affective filters imbuing the facts with an emotional valence that plays a huge part in determining what ultimately arises as our view of THE TRUTH.

Tyson and others are profoundly (and willfully) ignorant of philosophy. Belief in an objective reality is a critical element of the scientific method, but it’s just a belief, not the “truth.”

The “March For Science”

Derek Lowe explains why he won’t be marching. I agree.

[Update a while later]

Arthur Lambert isn’t attending either:

…there’s no denying this march is political. It is a mistake to position the scientific method against the Trump administration or any other one, for that matter. That would serve only to undermine a central premise of the march: that scientific knowledge is apolitical. Organizers argue that the march is “nonpartisan.” While this may be the official line, I’m skeptical of whether anything approaching it can actually be achieved, especially on the heels of a divisive election. For example, I recently spoke with a colleague who was organizing a poster-making session for the march. She proudly described her design as an “I’m With Her” arrow pointing toward planet Earth.

I was also “with her” last November, but that should be beside the point. I fear that, contrary to its mission of inclusion, the march may actually alienate many of those it seeks to convince. Scientists are highly educated, the academic version of the 1 percent Wall Street class. They are also overwhelming Democratic. I can assure you that this has little to no impact on their science or for the potential public impact of their findings. But it would not be unreasonable for a rural blue-collar worker, watching the marches from afar, to perceive them as yet another attack from the condescending elite. We cannot drum up the broad support for science that the march seeks by aggravating a deep divide already present in this country.

Want more Trump? This is how you get more Trump.

Bill Nye is the perfect talking head for a march against science:

March organizers have paid lip service to critical thinking and “diverse perspectives” in science. However, Nye is a good example of someone who promotes science as a close-minded ideology, not an open search for truth.

He attacks those who disagree with him on climate change or evolution as science “deniers.” He wouldn’t even rule out criminal prosecution as a tool. Asked last year whether he supported efforts to jail climate skeptics as war criminals, he replied: “Well, we’ll see what happens. Was it appropriate to jail the guys from ENRON?”

Real science encourages debate. It doesn’t insist that scientists march in lockstep. Or that they speak with one voice. In fact, scientists disagree on far more issues than the March organizers admit.

Bill Nye the lock-up-the-heretics guy.

[Update mid morning]

Bob Zimmerman says that the march against science is a Democrat Party operation.

“I love Neil de Grasse Tyson, but he’s wrong on climate.”

I don’t find him all that lovable, myself.

[Sunday evening update]

Judith Curry has a lot of links to “untangle the March for Science.”


[Monday-morning update]

Bill Nye the Constitutional-Ignorance Guy.

[Update a while later]

Nye freaks out when schooled by an actual scientist on CNN. Just like his meltdown with Tucker Carlson.
