Ben Santer

The ‘Pause’ in global warming is real and the computer models predicting dramatically increased temperatures have failed.

This is the shocking admission of a paper published this week in Nature Geoscience. It’s shocking because the paper’s lead author is none other than Ben Santer – one of the more vociferous and energetic alarmists exposed in the Climategate emails.

According to the paper’s abstract:

In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble.

And:

We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.

Translation: the real-world temperature increases were much smaller than our spiffy, expensive computer models predicted.

Its significance did not pass unnoticed by this veteran climate scientist:

His surprise is understandable given that, previously, alarmist scientists like Ben Santer have gone to great lengths to deny the existence of a ‘Pause’ in global warming, to pour scorn on those who have argued otherwise and to insist that their computer models are fundamentally reliable.

Indeed, only last week the Spectator published an article by one such Pause Denier – a scientist from the University of East Anglia (ground zero of the Climategate scandal), fondly known as the University of Easy Access, named Phil Williamson.

It is titled The Great Myth of the Global Warming Pause and it claims, somewhat imaginatively:

The Paris agreement will be the future, whereas the so-called global-warming hiatus is already history.

And let’s not forget that in the dog days of the Obama administration, alarmist scientists were so desperate to pooh-pooh the “Pause” in the run up to the Paris climate talks that they concocted a junk science paper – now the subject of a federal investigation – which used dodgy data to try to airbrush the Pause out of history.

Truly, as the Daily Caller notes, the alarmists’ flip-flopping on this subject has of late been remarkable. Do they believe in the ‘Pause’ (or ‘hiatus’ as they sometimes term it) or don’t they?

Santer recently co-authored a separate paper that purported to debunk statements EPA Administrator Scott Pruitt made that global warming had “leveled off.” But Santer’s paper only evaluated a selectively-edited and out-of-context portion of Pruitt’s statement by removing the term “hiatus.”

Moreover, climate scientists mocked Texas Republican Sen. Ted Cruz for talking about the global warming “hiatus” during a 2015 congressional hearing. Instead, activist scientists worked hard to airbrush the global warming slowdown from data records and advance media claim that it was a “myth.”

Santer and Carl Mears, who operate the Remote Sensing System satellite temperature dataset, authored a lengthy blog post in 2016 critical of Cruz’s contention there was an 18-year “hiatus” in warming that climate models didn’t predict.

The fact that Ben Santer is involved in this embarrassing retraction – his admission on the Pause is bad enough, but what the paper says about the unreliability of the computer models is breathtaking in its implications – will be particularly piquant to those who remember his prominent role in the Climategate emails.

Santer revealed himself to be one of the nastier and more aggressive members of Michael Mann’s “Hockey” team when he emailed one of his colleagues:

Next time I see Pat Michaels at a scientific meeting, I’ll be tempted to beat the crap out of him. Very tempted.

(Climatologist Pat Michaels, now of the Cato Institute, incurred Santer’s wrath by being one of the first climate scientists to pour cold water on Catastrophic Anthropogenic Global Warming theory. In other words, Michaels made the disgusting, punishment-worthy error of using actual science and being right).

But perhaps Santer’s lowest point was the occasion where he effectively hijacked one of the early IPCC Assessment Reports and ramped up the scaremongering in a way that had rather more to do with political activism than it did to science.

I describe it in my book Watermelons:

Ben who? Well quite. Unless his name rings a bell as the guy from the Climategate emails who wanted to “beat the crap out of” climate sceptic Pat Michaels, you almost certainly won’t have heard of him. Yet in the mid-90s this climate modeling nonentity was somehow placed in the extraordinary position of being able to dictate world opinion on global warming at the stroke of a pen.

He achieved this in his role as “lead author” of Chapter 8 of the scientific working group report on the IPCC’s Second Assessment Report (SAR). Nothing to write home about there, you might think, except that Santer was personally responsible for by far the most widely reported sentence in the entire report: the one from the Summary for Policy Makers (the only part of the IPCC’s Assessment Report most people actually bother to read) claiming “the balance of evidence suggests that there is a discernible human influence on global climate.”

But was this line actually true? Was this really a fair summary – the kind of summary the IPCC purports rigorously and definitively to give of us – of the general state of scientific understanding at that particular moment? Er, well not according to some of the scientists who’d contributed to that chapter of the report, no.

The original version of the chapter – as agreed on and signed off by all 28 contributing authors – expressed considerably more doubt about AGW than was indicated in Santer’s summary. It included these passages:

“None of the studies cited above has shown clear evidence that we can attribute the observed changes to the specific cause of increases in greenhouse gases.”

“No study to date has positively attributed all or part (of the climate change observed) to (man-made) causes.”

“Any claims of positive detection and attribution of significant climate change are likely to remain controversial until uncertainties in the total natural variability of the climate system are reduced.”

“When will an anthropogenic climate be identified? It is not surprising that the best answer to the question is “We do not know.”

Strangely, none of these passages made it to the final draft. They were among 15 deleted after the event by Santer, who also inserted a phrase entirely of his own to the effect that “the body of statistical evidence” now “points to a discernible human influence on climate.” In other words, the chapter did not represent the “consensus” position reached by 28 scientists. What it in fact represented was the scientifically unsupported opinion of one man, Benjamin D Santer.

We climate rationalists do still get an awful lot of stick from the alarmists for our old fashioned belief that scientists should stick to the evidence and use actual data rather than plucking stuff from thin air based on their fanciful notions of what ought to be true or what might get them more grant-funding.

Indoctrinating the youth central to warming campaign

Indoctrinating the youth central to warming campaign

Catching students before they have learned enough to spot the flaws in the climate narrative is their goal.

It’s not a new tactic.

“Give me four years to teach the children and the seed I have sown will never be uprooted,” said Lenin.

The brilliant mathematician and CFACT contributor writes in a pair of articles exclusive to CFACT.org, that despite their daunting institutional grip, the warming campaign’s goal of total educational hegemony is, fortunately, falling short.

“Last year,” David writes, “a major poll revealed that among high and middle school science teachers, at least a third are skeptical of global warming alarmism. They are teaching the real scientific debate.”

Moreover, David further explains, “The New York Times recently ran a long article complaining that President Trump quitting the Paris Agreement has emboldened high school students to be skeptical of climate change alarmism.”

Open minds among teacher and student alike?

Not a good thing in the NYT’s worldview.

Must students truly be taught the hectoring pronouncements of climate alarmists as incontrovertible truth, but be denied knowledge of the facts that expose their dogma?

More and more students and educators are thinking outside the politicized climate box.

As David Wojick enthuses, this is “good news” indeed.

The New ‘Consensus’ On Global Warming – a shocking admission by “Team Climate”

The New ‘Consensus’ On Global Warming – a shocking admission by “Team Climate”

From the “well maybe there was a hiatus after all” walkback department. Even Mann is on board with this paper.

By MICHAEL BASTASCH AND DR. RYAN MAUE

A scientific consensus has emerged among top mainstream climate scientists that “skeptics” or “lukewarmers” were not long ago derided for suggesting — there was a nearly two-decade long “hiatus” in global warming that climate models failed to accurately predict or replicate.

A new paper, led by climate scientist Benjamin Santer, adds to the ever-expanding volume of “hiatus” literature embracing popular arguments advanced by skeptics, and even uses satellite temperature datasets to show reduced atmospheric warming.

More importantly, the paper discusses the failure of climate models to predict or replicate the “slowdown” in early 21st century global temperatures, which was another oft-derided skeptic observation.

“In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble,” reads the abstract of Santer’s paper, which was published Monday.

“Over most of the early twenty-first century, however, model tropospheric warming is substantially larger than observed,” reads the abstract, adding that “model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.”

The paper caught some prominent critics of global climate models by surprise. Dr. Roger Pielke, Sr. tweeted “WOW!” after he read the abstract, which concedes “model tropospheric warming is substantially larger than observed” for most of the early 21st Century.

It’s more than a little shocking.

Santer recently co-authored a separate paper that purported to debunk statements EPA Administrator Scott Pruitt made that global warming had “leveled off.” But Santer’s paper only evaluated a selectively-edited and out-of-context portion of Pruitt’s statement by removing the term “hiatus.”

Moreover, climate scientists mocked Texas Republican Sen. Ted Cruz for talking about the global warming “hiatus” during a 2015 congressional hearing. Instead, activist scientists worked hard to airbrush the global warming slowdown from data records and advance media claim that it was a “myth.”

Santer and Carl Mears, who operate the Remote Sensing System satellite temperature dataset, authored a lengthy blog post in 2016 critical of Cruz’s contention there was an 18-year “hiatus” in warming that climate models didn’t predict.

They argued “examining one individual 18-year period is poor statistical practice, and of limited usefulness” when evaluating global warming.

“Don’t cherry-pick; look at all the evidence, not just the carefully selected evidence that supports a particular point of view,” Santers and Mears concluded.

Cruz’s hearing, of course, was the same year the National Oceanic and Atmospheric Administration (NOAA) released its “pause-busting” study. The study by lead author Tom Karl purported to eliminate the “hiatus” from the global surface temperature record by adjusting ocean data upwards to correct for “biases” in the data.

Democrats and environmentalists praised Karl’s work, which came out before the Obama administration unveiled its carbon dioxide regulations for power plants. Karl’s study also came out months before U.N. delegates hashed out the Paris agreement on climate change.

Karl’s study was “verified” in 2016 in a paper led by University of California-Berkeley climate scientist Zeke Hausfather, but even then there were lingering doubts among climate scientists.

Then, in early 2016, mainstream scientists admitted the climate model trends did not match observations — a coup for scientists like Patrick Michaels and Chip Knappenberger who have been pointing out flaws in model predictions for years.

John Christy, who collects satellite temperature data out of the University of Alabama-Huntsville, has testified before Congress on the failure of models to predict recent global warming.

Christy’s research has shown climate models show 2.5 times more warming in the bulk atmosphere than satellites and weather balloons have observed.

Now, he and Santer seem to be on the same page — the global warming “hiatus” is real and the models didn’t see it coming.

Santer’s paper argues the “hiatus” or “slowdown” in warming “has provided the scientific community with a valuable opportunity to advance understanding” of the climate system and how to model it.

What’s interesting, though, is Santer and his co-authors say their paper is “unlikely to reconcile the divergent schools of thought regarding the causes of differences between modeled and observed warming rates.”

In other words, the “uncertainty monster” is still a problem.

Causes of differences in model and satellite tropospheric warming rates

Abstract:

In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble. Because observations and coupled model simulations do not have the same phasing of natural internal variability, such decadal differences in simulated and observed warming rates invariably occur. Here we analyse global-mean tropospheric temperatures from satellites and climate model simulations to examine whether warming rate differences over the satellite era can be explained by internal climate variability alone. We find that in the last two decades of the twentieth century, differences between modelled and observed tropospheric temperature trends are broadly consistent with internal variability. Over most of the early twenty-first century, however, model tropospheric warming is substantially larger than observed; warming rate differences are generally outside the range of trends arising from internal variability. The probability that multi-decadal internal variability fully explains the asymmetry between the late twentieth and early twenty-first century results is low (between zero and about 9%). It is also unlikely that this asymmetry is due to the combined effects of internal variability and a model error in climate sensitivity. We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.
