A failure of peer review

Judith Curry’s website has a comment about the recent paper in Nature, stating that the oceans are absorbing unexpectedly large amounts of heat. The writer, Nic Lewis, finds some problems with it. (Hat tip: Legal Insurrection)

On page 1 they say:

From equation (1), we thereby find that ΔAPOClimate = 23.20 ± 12.20 per meg, corresponding to a least squares linear trend of +1.16 ± 0.15 per meg per year[ix]

A quick bit of mental arithmetic indicated that a change of 23.2 between 1991 and 2016 represented an annual rate of approximately 0.9, well below their 1.16 value. As that seemed surprising, I extracted the annual ΔAPO best-estimate values and uncertainties from the paper’s Extended Data Table 4[x] and computed the 1991–2016 least squares linear fit trend in the ΔAPOClimate values. The trend was 0.88, not 1.16, per meg per year, implying an ocean heat uptake estimate of 10.1 ZJ per year,[xi] well below the estimate in the paper of 13.3 ZJ per year.[xii]

Later, he concludes:

CONCLUSIONS

The findings of the Resplandy et al paper were peer reviewed and published in the world’s premier scientific journal and were given wide coverage in the English-speaking media. Despite this, a quick review of the first page of the paper was sufficient to raise doubts as to the accuracy of its results. Just a few hours of analysis and calculations, based only on published information, was  sufficient to uncover apparently serious (but surely inadvertent) errors in the underlying calculations.

Moreover, even if the paper’s results had been correct, they would not have justified its findings regarding an increase to 2.0°C in the lower bound of the equilibrium climate sensitivity range and a 25% reduction in the carbon budget for 2°C global warming.

Because of the wide dissemination of the paper’s results, it is extremely important that these errors are acknowledged by the authors without delay and then corrected.

Of course, it is also very important that the media outlets that unquestioningly trumpeted the paper’s findings now correct the record too.

But perhaps that is too much to hope for.

Maybe it’s a problem with Four-Letter Agencies

Reason Magazine says the ACLU has become “a liberal organization with an interest in civil liberties”.

First, the ACLU ran an anti-Brett Kavanaugh video ad that relied entirely on something that no committed civil libertarian would countenance, guilt by association. And not just guilt by association, but guilt by association with individuals that Kavanaugh wasn’t actually associated with in any way, except that they were all men who like Kavanaugh had been accused of serious sexual misconduct. The literal point of the ad is that Bill Clinton, Harvey Weinstein, and Bill Cosby were accused of sexual misconduct, they denied it but were actually guilty; therefore, Brett Kavanaugh, also having been accused of sexual misconduct, and also having denied it, is likely guilty too.

Can you imagine back in the 1950s the ACLU running an ad with the theme, “Earl Warren has been accused of being a Communist. He denies it. But Alger Hiss and and Julius Rosenberg were also accused of being Communists, they denied it, but they were lying. So Earl Warren is likely lying, too?”

Meanwhile, yesterday, the Department of Education released a proposed new Title IX regulation that provides for due process rights for accused students that had been prohibited by Obama-era guidance. Shockingly, even to those of us who have followed the ACLU’s long, slow decline, the ACLU tweeted in reponse that the proposed regulation “promotes an unfair process, inappropriately favoring the accused.” Even longtime ACLU critics are choking on the ACLU, of all organizations, claiming that due proess protections “inappropriately favor the accuse.”

 

Race, violence, and prejudice

Clayton Cramer fielded a question from a journalist regarding the perceived increase in police shootings of armed black men.

I’ll send over a few questions if that okay with you… I really want to capture the increased incident of police and armed black men. Activist seem to believe there is racism at the core of these incidents.1. What was your response to the shooting of Jemel Roberson two days ago?

I confess that I missed this. The police officer clearly reacted too quickly and wrongly.

2. Do you believe racism is something that is a factor in these shootings?

I think it is important to distinguish between racism and prejudice. A racist would assume that a different race is intrinsically different or inferior, and often that is expressed as hatred. Many people have prejudices based on race, sex, or other identities that may not be associated with hate. There are times that those prejudices may have a rational basis when applied to unknown members of that group. Let me give you an example.

This is a pretty important point. In another discussion elsewhere with someone else, I felt the need to distinguish between “racial” distinctions and “racist” distinctions. Allocating more funds to treat sickle cell trait in largely black areas than elsewhere is a racial distinction, but not a racist one.

Many years ago, I was walking home from college on a pedestrian path that was pretty isolated. There was a 10 foot high concrete wall on one side, and a chain link fence with a stream and forest on the other. Ahead of me about 50 yards was a young woman also walking away from campus. There was no one else around. Because I was a bit taller than her, I was slowly gaining on her as I walked this path. After a couple minutes, I realized that she had increased her pace; soon, she was almost running.

My first reaction was, “Why is she afraid of me? I am a nice person; I will not hurt her. Is it just because I’m a man?” The answer, I am sure, was Yes. Nasty prejudice. But a rational prejudice. She did not know me. Effectively all rapists are men. That means that men are 2x as likely to be rapists as people in general: unknown men are a disproportionate risk. Few men are rapists; there were 124,000 rapes in America in 2015 (https://ucr.fbi.gov/crime-in-the-u.s/2015/crime-in-the-u.s.-2015/tables/table-1) in a nation of 160 million men, and because rapists are usually serial offenders, there are probably far less than 124,000 men who are rapists.

What if she assumes the worst about a man, and he is harmless (like me)? She gets a bit of a cardio workout from trying to get away. What if she assumes a man is harmless and he is a rapist? The consequences may be quite severe. So her reaction qualifies as a rational reaction to her prejudice.

Climate Change Questions

From Watts Up With That:

The issue of climate change (aka global warming) depends on the answers to three questions being “yes”.
1) Is the planet getting warmer?
2) Is the warming due to human activity?
3) Is this warming going to lead to disaster?

It seems 96% of atmospheric scientists answer question 1 as “yes”.

In another survey, 29% of scientists surveyed say it’s entirely human activity, and 38% say “mostly” (60-80%) human activity.

In a third survey, half believe the effects will be primarily (47%) or exclusively (3%) negative over the next half century.

So, the consensus for an anthropogenic climate change disaster is
96% X 67% X 50% = 32%.

It would be interesting to see the answer to a question 2A) “Can humans significantly reverse the warming of the planet?”

Hate crimes against Jews up during Trump administration, but…

Source: Hot Air.

Today the NY Times published a piece today highlighting the fact that half of all hate-crimes in cosmopolitan, progressive New York this year are Anti-Semitic in nature. Furthermore, the piece delicately points out that the perpetrators of these crimes aren’t white supremacists.

Contrary to what are surely the prevailing assumptions, anti-Semitic incidents have constituted half of all hate crimes in New York this year, according to the Police Department. To put that figure in context, there have been four times as many crimes motivated by bias against Jews — 142 in all — as there have against blacks. Hate crimes against Jews have outnumbered hate crimes targeted at transgender people by a factor of 20.

[snip]

If anti-Semitism bypasses consideration as a serious problem in New York, it is to some extent because it refuses to conform to an easy narrative with a single ideological enemy. During the past 22 months, not one person caught or identified as the aggressor in an anti-Semitic hate crime has been associated with a far right-wing group, Mark Molinari, commanding officer of the police department’s Hate Crimes Task Force, told me.
