Nate Silver goes from hero to goat, convicted by the Left of apostasy

Summary: The climate refuses to warm as predicted, the IPCC refuses to endorse claims of extreme climate, public supports fades, and the Left grows desperate. So they use their influence in the media to punish any deviance from their orthodoxy. Nate Silver and Roger Pielke Jr are the latest to feel their wrath. See the links to other posts in this series in section 8.

Paraphrasing an ancient legal aphorism:

When the facts are against you, argue the theory.

When the theory is against you, argue the facts.

When both are against you, loudly smear your opponent.

Introduction The arbiter of good journalism speaks A typical attack from the Left Krugman is loyal to his tribe, not science Rare, brave defenders speak out A climate scientist looks at the commentary Update: peer-reviewed research on this issue For More Information

(1) Introduction

Pity Nate Silver. Hero of the Left for his successful take-down of GOP’s election forecasts, shooting down their delusions about Romney’s chances of victory. Good Leftists like Brad DeLong and Paul Krugman heaped praises on Silver, catapulting him into a sweet gig at ESPN. The poor guy thought the applause was for his use of numbers in pursuit in truth, when it was purely tribal. Their applause were just tribal grunts — we good, they bad — in effect chanting…

“Two legs good. Four legs bad.”

Right out of the box at his new venture, ESPN’s FiveThirtyEight, Silver committed apostasy, and the Left reacted with the fury true believers mete out to their betrayers. He posted “Disasters Cost More Than Ever — But Not Because of Climate Change” by Roger Pielke Jr (Prof Environmental Studies, U CO-Boulder), 19 March 2014. Also see his follow-up article, with more detail.

(Note that Brad DeLong was originally mentioned above in error. He praised Silver’s election reporting, but had not written about Pielke Jr’s 538 article at the time of this post. He has since joined the Left’s lynch mob, displaying their indifference to the climate science literature.)

(2) The arbiter of good journalism speaks

“FiveThirtyEight’s disappointing science section“, By Alexis Sobel Fitts, Columbia Journalism Review, 2014 — ” Science journalism could use an infusion of analysis, but FiveThirtyEight isn’t yet doing it rigorously or objectively.”

The internet hates Nate Silver today — at least the small quotient closely following the launch of his new site, FiveThirtyEight, this week—and with ample reason. When Silver wrote, “It’s time to make news a little nerdier,” in his site-launch manifesto, he was issuing a call to arms against the mainstream press. Because by nerdier, he really meant better. “Plenty of pundits have really high IQs, but they don’t have any discipline in how they look at the world,” he told New York magazine last week, promising to produce a site free of such “bullshit.” But it’s always risky to bite the hand that publicizes you …

.

That’s why so many writers have been concerned about FiveThirtyEight’s climate writer, Roger Pielke, Jr, a University of Colorado professor, who ThinkProgress once called “the most debunked person in the science blogosphere, possibly the entire Web.” {blogger Joe Romm, 24 October 2009} Though Pielke has a deep pool of knowledge about climate change, as The Week has chronicled, he also has strong personal opinions and a history of using data to back them up against the larger scientific community. President Obama’s science adviser, John Holdren, has “accused [Pielke] of selective quotation and obfuscation,” and though Pielke claims to believe in climate change, Foreign Policy has included him on its list of climate skeptics. … Pielke’s first post for the site covers the link between climate change and extreme weather—or lack thereof: “Disasters Cost More Than Ever—But Not Because of Climate Change.” In the post, he first shows the rising rate of global disaster losses, then adjusts the figure for the rise in global GDP — showing that global disaster losses have actually flatlined. “We’re seeing ever-larger losses simply because we have more to lose — when an earthquake or flood occurs, more stuff gets damaged,” writes Pielke. Which is an interesting point, but not relevant to climate change.

This is daft on many levels. First the author’s belief that journalists — Christina Larson and Joshua Keating — and climate activists like Joe Romm are qualified to evaluate climate scientists.

Second, how can anyone take seriously Romm’s statement that Pielke is “the most debunked person in the science blogosphere”? That Fitts considers Romm’s statement to be evidence tells us much about CJR’s objectivity. Fitts also cite an article in Foreign Policy, which classic hack journalism. It gives allegations without context (e.g. they cite statements by Pielke as “skepticism” without defining the term, or telling readers he’s re-stating conclusions of the IPPC).

Third, they dismiss Pielke’s research as “not relevant to climate change.” Which is correct. But Pielke is trained as a political scientist, and the increasing damages from weather is cited as evidence by those seeking public policy changes.

Fourth, consider the CJR’s opening indictment: “he {Pielke} also has strong personal opinions and a history of using data to back them up against the larger scientific community”. That’s a description of good science, and many of great scientists. It equally applies to climate scientists far more politically active (e.g., James Hanson and Michael E. Mann).

(3) A typical attack from the Left

(a) “Nate Silver’s FiveThirtyEight and the dangers of being ideologically neutral“, Ryan Cooper (journalist), The Week, 19 March 2014. This is worth a detailed look.

“By claiming the mantle of pure analysis, Silver is falling into a familiar journalistic trap. … In an attempt to focus solely on objective analysis, Silver is ignoring one of the hardest-won journalistic lessons of the last decade — there is no such thing as ideology-free journalism.”

That’s what right-wingers have long said about journalists. Odd that if journalists know this, they don’t label their articles with the the writers’ ideology to provide transparency and disclosure.

“That kind of squid-ink careerist nonsense …”

Perhaps Ryan Cooper believes his ideology empowers him to judge disputes between scientists. It’s a common delusion of journalists. As C. S. Lewis said:

“He is like a dog which should imagine it understood fire-arms because its hunting instinct and love for its master enable it to enjoy a day’s shooting.”

The rest is inspired guessing posing as journalism.

(b) Hysteria takes hold on the Left; they swarm in defense of their orthodoxy

It’s a Two Minute Hate! It’s sad to see how the Left has decayed in America, so that this is what they consider to be rational thought — mirroring a similar decay on the Right. Both sides clearly see this in their opponents, and laugh. America cries.

In these posts we see how the politics of climate change has become a cacophony, poisonous and ineffectual. Which is fine for the Right, who wants nothing done, but defeat for the Left.

(4) Krugman is loyal to his tribe, not science

“Tarnished Silver“, blog of the NY Times, 23 March 2014 — Excerpt:

Similarly, climate science has been developed by many careful researchers who are every bit as good at data analysis as Silver, and know the physics too, so ignoring them and hiring a known irresponsible skeptic to cover the field is a very good way to discredit your enterprise.

A social scientist like Krugman knows quite well that scientists in a field routinely disagree. That’s how science advances. Citing these disputes with no reference to consensus opinion is just smearing Pielke for the public. Especially when so much of what Pielke writes defending the IPCC’s work (alluded to in the activist’s post Krugman cites; also note the correction at the end).

Note how Leftists cite articles at hard-core activist websites like Skeptical Science and ThinkProgress as gospel. Would Krugman want laypeople to judge his work — and the mainstream of economics — from economists cited in a conservative’s blog?

Also, we see here a larger phenomenon: these days the IPCC seldom appears in Leftists’ articles, except to mention that its insufficiently alarmist.

(5) Rare, brave defenders speak out (updated)

(a) “In defense of Nate Silver“, Michael Brendan Dougherty, The Week, 20 March 2014 — “FiveThirtyEight’s critics are unhinged. If Silver’s data-driven approach gets in the way of your political aims, so much the better.” Excerpt:

Silver is plainly right that a kind of innumeracy pervades journalism. Many journalists don’t know how to evaluate academic studies. If, occasionally, Silver’s empirical research gets in the way of your ideological priors, you have an opportunity to rethink them. He’s done you a favor, not a disservice.

(b) “In the Eye of the Storm“, James Hanley (Assoc Prof of Political Science, Adrian College), Ordinary Times, 10 May 2014 — Conclusion:

It seems that a peaceful, non-vitriolic discussion of AGW is not possible in today’s political climate — not even if you correctly quote the IPCC reports.

(6) A climate scientist looks at the commentary

Judith Curry (Prof Atmospheric Science, GA Inst Tech) posted a lengthy review of this fight at her website. Excerpt:

The post is vintage Roger Pielke Jr, citing results from the IPCC SREX and using data from SwissRe. RP Jr’s post at 538 has elicited what is probably the most reprehensible and contemptible smear job that I have ever seen of a scientist, at least from an organization that has any pretense of respectability. Kiley Kroh of ClimateProgress has a post entitled Nate Silver’s New Science Writer Ignores the Data on Climate Science. … In this article, there is not a single critique of anything RP Jr actually said in his 538 post. Before looking at the author of the post, I assumed it was either Joe Romm or Michael Mann, since it has their unmistakable hatchet job signature. Instead, the author is Kiley Kroh, co-editor of Climate Progress. … ClimateProgress is an element of ThinkProgress, a liberal American political blog that is an outlet for the Center for American Progress. CAP’s first President and CEO was John Podesta, who is now a Special Advisor to the Obama Administration (and also Chairman of the Board of CAP). Pielke Jr’s analyses are clearly inconvenient to the political agenda of Obama/Holdren/Podesta. RP Jr. has written on this topic at the New Republic An Obama Advisor is Attacking me for Testifying That Climate Change Hasn’t Increased Extreme Weather. … Well as recently as 5 years ago, I never thought I’d live to see the day when I am very grateful that I have tenure at a university, which provides my job with some protection against politically inconvenient scientific analyses.

(7) Peer-reviewed research on this issue



Pielke’s research is not only in accord with the findings of the IPCC, but is also supported by a body of peer-reviewed research. Red emphasis added.

(a) Some of Pielke’s papers on this topic:

(b) A review of the literature: “Have disaster losses increased due to anthropogenic climate change?“, Laurens Bouwer, Bulletin of the American Meteorological Society, January 2011 — Abstract:

The increasing impact of natural disasters over recent decades has been well documented, especially the direct economic losses and losses that were insured. Claims are made by some that climate change has caused more losses, but others assert that increasing exposure due to population and economic growth has been a much more important driver. Ambiguity exists today, as the causal link between climate change and disaster losses has not been addressed in a systematic manner by major scientific assessments. Here I present a review and analysis of recent quantitative studies on past increases in weather disaster losses and the role of anthropogenic climate change. Analyses show that although economic losses from weather related hazards have increased, anthropogenic climate change so far did not have a significant impact on losses from natural disasters. The observed loss increase is caused primarily by increasing exposure and value of capital at risk. This finding is of direct importance for studies on impacts from extreme weather and for disaster policy. Studies that project future losses may give a better indication of the potential impact of climate change on disaster losses and needs for adaptation, than the analysis of historical losses.

(c) “Normalizing economic loss from natural disasters: A global analysis“, Eric Neumayer and Fabian Barthel, Global Environmental Change, February 2011 — Abstract:

Climate change is likely to lead to an increase in the frequency and/or intensity of certain types of natural hazards, if not globally, then at least in certain regions. All other things equal, this should lead to an increase in the economic toll from natural disasters over time. Yet, all other things are not equal since affected areas become wealthier over time and rational individuals and governments undertake defensive mitigation measures, which requires normalizing economic losses if one wishes to analyze trends in economic loss from natural disasters for detecting a potential climate change signal. In this article, we argue that the conventional methodology for normalizing economic loss is problematic since it normalizes for changes in wealth over time, but fails to normalize for differences in wealth across space at any given point of time. We introduce an alternative methodology that overcomes this problem in theory, but faces many more problems in its empirical application. Applying, therefore, both methods to the most comprehensive existing global dataset of natural disaster loss, in general we find no significant upward trends in normalized disaster damage over the period 1980–2009 globally, regionally, for specific disasters or for specific disasters in specific regions. Due to our inability to control for defensive mitigation measures, one cannot infer from our analysis that there have definitely not been more frequent and/or more intensive weather-related natural hazards over the study period already. Moreover, it may still be far too early to detect a trend if human-induced climate change has only just started and will gain momentum over time.

(d) Not peer-reviewed, but an excellent guide for laypeople to the research: “What is driving the rising cost of natural disasters?“, Prof John McAneney and Dr. Ryan Crompton (Macquarie U), Trébol Magazine, 2013 — Opening:

It is a widely held view that climate change arising from human activity is increasing the cost of natural disasters. This perception is false. While it is undeniable that the economic cost of natural disasters is rising rapidly, it is doing so because of growing concentrations of population and wealth in disaster-prone regions. So far studies of long-term insurance or economic disaster loss histories caused by extreme weather — tropical cyclones, floods, bushfires (wildfires) and storms — have been unable to identify a contribution from human-induced climate change. This is true for many different natural perils and across jurisdictions.

(e) “Flood risk and climate change: global and regional perspectives“, Zbigniew W. Kundzewicz et al, Hydrological Sciences Journal, March 2014 — Abstract:

A holistic perspective on changing rainfall-driven flood risk is provided for the late 20th and early 21st centuries. Economic losses from floods have greatly increased, principally driven by the expanding exposure of assets at risk. It has not been possible to attribute rain-generated peak streamflow trends to anthropogenic climate change over the past several decades. Projected increases in the frequency and intensity of heavy rainfall, based on climate models, should contribute to increases in precipitation-generated local flooding (e.g. flash flooding and urban flooding). This article assesses the literature included in the IPCC SREX report and new literature published since, and includes an assessment of changes in flood risk in seven of the regions considered in the recent IPCC SREX report — Africa, Asia, Central and South America, Europe, North America, Oceania and Polar regions. Also considering newer publications, this article is consistent with the recent IPCC SREX assessment finding that the impacts of climate change on flood characteristics are highly sensitive to the detailed nature of those changes and that presently we have only low confidence in numerical projections of changes in flood magnitude or frequency resulting from climate change.
