Another disturbing article about climate change. Fortunately we have the IPCC!

Summary:  Climate change is among our most important public policy issues, and shows our broken ability to see and understand our world around us.  Today Esquire gives us a powerful but misleading story about our imminent doom, one rich with lessons for us. Expect to see many more of these before November’s United Nations Climate Change Conference in Paris.   (2nd of 2 posts today.}

“The unwise man is awake all night, worries over and again. When morning rises he is restless still.”
— Norse proverb.

Overton Window

Today’s reading is “When the End of Human Civilization Is Your Day Job” by John H. Richardson in Esquire — “Among many climate scientists, gloom has set in. Things are worse than we think, but they can’t really talk about it.”

It’s a sad story, but not the one Richardson thinks he’s telling. Glaciologist Jason Box has an apocalyptic forecast for climate change. This has taken a psychological toll on him and his family. Richardson misrepresents the story, however, by neglecting to mention that Box’s views are outside the consensus of climate scientists as seen in the reports of the IPCC.

Like most alarmist articles in the media, the letters “IPCC” don’t even appear. Focusing on the views of scientists with forecasts more extreme than the IPCC while discrediting those on the other side of the curve (“skeptics”) is an attempt to shift the Overton Window — and increase public support for large-scale regulation of energy and economic activity.

Dueling remarks about the Pope & the climate from Rush & Jeb! We can learn from both.

Summary: Two voices on the Right illustrate vital aspects of our largely dysfunctional political system, bad news and good news about the climate wars (and the Pope). We can learn from the former and gain inspiration from the latter.  {2nd of 2 posts today.}

“It is extremely likely (95 – 100% certain) that human activities caused more than half of the observed increase in global mean surface temperature from 1951 to 2010.”

— From the IPCC’s AR5 Working Group I report.

Unicorn politics

We can do it.

Author Marc A. Cirigliano (see his books) tweeted today about two interesting articles by conservatives. Rush shows us why climate change has become yet another example of dysfunctional US public policy, locked in a futile debate — and religion so often just a prop used by both sides. I am no fan of Jeb Bush, but yesterday he said some sensible things about climate change and the Pope. If we put aside our ideological blinders, both Left and Right can learn from these two men.

Rush shows us the problem

Transcript of the Rush Limbaugh show: “The Pope’s Leaked Marxist Climate Rant“, 16 June.

“Meanwhile, we’re in a ten-year cooling period! There hasn’t been any warming. The whole thing is a hoax, and we’ve got this leak of a papal encyclica on the “fact” that global warming is man-made. It’s man-caused and we have almost a religious commandment here to deal with it. I mean, it’s just right out of the Democrat Party.”

Years ago I asked Michael Cohen if there were people on the stage of America who didn’t believe in global warming. Rush proves Cohen correct and me wrong about this (again). But if we listen closely, he makes some valid points.

First, he makes the obvious point about the hypocrisy of the Left suddenly believing the Pope is a guide to the good and the true. Are they going to follow his teachings on homosexuality, the role of women, the use of birth control and abortion? Probably not.

Second, later in the program Rush points to actual science — and demonstrates how it is often lost in the political conflict that’s rendered US public policy so dysfunctional (except in matters of direct interest to the 1% or the Deep State).

What happened to NASA’s missing weather satellites & their vital data about global warming?

Summary: The world has a new and serious mystery, right up there with “Where in the World Is Carmen Sandiego?” and “The President’s plane is missing!” What happened to NASA’s satellites that measure global temperatures? They appear to have disappeared from the nation’s major newspapers, their valuable information about global warming lost from view. Today’s post retrieves it to help you understand one of the top public policy issues of our time.  {1st of 2 posts today.}

(1)  Where are NASA’s satellites?

NASA has launched a fleet of satellites which (among other things) since 1979 have measured Earth’s temperature in the lower troposphere, with better coverage and consistency than the surface temperature networks — with their spotty coverage of the world’s seas and scores of national weather bureaus (many poorly funded) that the collect land temperatures. Being careful and thorough, NASA pays two teams to analyze the data:  Remote Sensing Systems (RSS) and the University of Alabama in Huntsville (UAH).

Here are the satellites whose sensors — at vast cost — have driven the RSS dataset since 1979, among the most valuable results from the space program (see the end of the post for a more detailed chart).

Oddly, the results of the satellites’ temperature measurements have almost disappeared from much of the news. As a crude measure, there are 2,970 Google News stories in the past year mentioning “hottest year”, but only 637 (21%) include the word “satellite” — and few of those are in the mainstream news. For example, per Google News only 1 of the many “hottest year” stories in the New York Times include both terms, 2 of the 49 science articles in the Washington Post (here and here), and 6 of the 17 in the Wall Street Journal.

The eclipse of this data is mysterious since it would provides a contrary perspective to the “hottest year” stories, since neither RSS nor UAH shows 2014 as a record (details here). But whatever the reason, we need not rely on journalists to tell us the expensive findings of this NASA research.

About the imminent spike in global warming

Summary: Our dysfunctional politics result largely from polarized views of Americans, both sides shaped by skillful and expensive propaganda. To break free we’ll need to learn their methods and develop far deeper skepticism. This is another in a series of posts looking at examples of our minds being molded by pros. It discusses the work of climate activists, but it’s vital to understand that both sides do this — because it works.  {2nd of 2 posts today.}

Global Warming

Yesterday’s post discussed the largely erroneous framing in an article about climate change by investment expert Barry Ritholtz at Bloomberg. How do intelligent, educated people become so convinced by the propaganda of climate activists, dismissing any who disagree with them as “deniers”?

We might find an answer by looking at the work of activists, such as Joe Romm (note that most climate activists are paid employees, unlike most of those on the Right). This post follows his chain of evidence in a typical article, showing how his bold conclusions rest on misrepresentations of the literature, and exaggerating the scope and certainty of specific papers.

The work by activists have large effects because liberals often read only activists, giving them a misunderstanding of climate science — exacerbated because activists seldom cite the work of institutions like the IPCC (designed to make the work of scientists understandable to laypeople).

Today’s example: “NOAA Study Confirms Global Warming Speed-Up Is Imminent” at ThinkProgress, 5 June 201 — Opening …

A major new study from NOAA finds more evidence that we may be witnessing the start of the long-awaited jump in global temperatures. As I reported in April, many recent studies have found that we are about to enter an era of even more rapid global warming. … The new study in Science from a team of NOAA scientists, “finds that the rate of global warming during the last 15 years has been as fast as or faster than that seen during the latter half of the 20th Century,” as NOAA explains.

… What happens when these various temporary factors stop? Karl explained: “Once these factors play out, and they may have already, global temperatures could rise more rapidly than what we have seen so far.” In other words, the long-awaited jump is global temperatures is likely imminent.

The cracks appear right at the start of this. Note the jump between Karl’s careful “may have already … could rise” and Romm’s “likely imminent”. Romm also omits the cautious language Karl gives in the NOAA’s well-written (as always) press releases (first one, second one) …

The Pause in global warming has ended. Now see the rest of the story.

Summary: A new paper in Science grapples with pause in atmospheric warming, one of the frontiers in climate science. I expect that the news media will give it mega-coverage, total applause (papers that challenge the paradigm are ignored). Here are comments by climate scientists giving the vital context that few journalists will mention. The important thing to know, a secret to journalists, is that laypeople should focus on the trend of the literature — or summaries like those of the IPCC — rather than the cherry-picked papers highlighted by activists on both sides. {2nd of 2 posts today.}

A major new report just published in Science by a team of NOAA climatologists will roil the debate about the vital subject: “Possible artifacts of data biases in the recent global surface warming hiatus” by Thomas R. Karl et al. The timing is significant, one of a series of papers appearing before November’s United Nations Climate Change Conference in Paris.  Abstract…

Much study has been devoted to the possible causes of an apparent decrease in the upward trend of global surface temperatures since 1998, a phenomenon that has been dubbed the global warming “hiatus.” Here we present an updated global surface temperature analysis that reveals that global trends are higher than reported by the IPCC, especially in recent decades, and that the central estimate for the rate of warming during the first 15 years of the 21st century is at least as great as the last half of the 20th century. These results do not support the notion of a “slowdown” in the increase of global surface temperature.

Excerpts from the paper.

The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report concluded that the global surface temperature “has shown a much smaller increasing linear trend over the past 15 years [1998-2012] than over the past 30 to 60 years.” The more recent trend was “estimated to be around one-third to one-half of the trend over 1951-2012.” The apparent slowdown was termed a “hiatus,” and inspired a suite of physical explanations for its cause, including changes in radiative forcing, deep ocean heat up-take, and atmospheric circulation changes.

While these analyses and theories have considerable merit in helping to understand the global climate system, other important aspects of the “hiatus” related to observational biases in global surface temperature data have not received similar attention. In particular, residual data biases in the modern era could well have muted recent warming, and as stated by IPCC, the trend period itself was short and commenced with a strong El Niño in 1998. Given recent improvements in the observed record and additional years of global data (including a record-warm 2014), we re-examine the observational evidence related to a “hiatus” in recent global surface warming.

… It is also noteworthy that the new global trends are statistically significant and positive at the 0.10 significance level for 1998–2012 {i.e., weakly significant}.

Good news: the warming pause finally appears in the news as journalists learn about science.

Summary:  Telling the public about climate change is among the most difficult challenges for journalists, ever. Complex, rapidly changing, no consensus among scientists beyond a few basics about mechanisms and history, and highly politicized. Here we look at two examples, good and not-so-good. These show progress, and also how the Left’s dogmatic adherence to its narrative has forced them to abandon science (a commonplace in history for both Left and Right).

(1)  Good journalism

Sample #1: “Scientists now know why global warming has slowed down and it’s not good news for us“, Jeffery DelViscio, Quartz, 27 February 2015.

They accurately report two studies. They quote scientists — not activists. They often put things in context. Most important, they break the Left’s narrative of denying the pause, which for several years been one of the hot topics in climate science.

Roberts told Quartz that this all suggests our current warming pause is unique, but, despite the low probability, it is also “very possible” that the pause could continue a few more years. And that wouldn’t be inconsistent with what we know about the effects of the heat-trapping ocean oscillations at work in the Science study.

… >Some even say that 2014, the hottest year on record, already marked the end of the hiatus. But Roberts of the Met Office advised caution before calling it officially off. “I would argue that we need a run of several unusually warm years to be able to definitively identify the end,” he said.

All of the researchers who spoke to Quartz about the two studies agreed that the warming pause was just that. “Eventually we expect temperatures to ‘catch up,’ but it may take longer than five years for that to happen,” Roberts told Quartz.

The article’s overall frame is, however, incorrect. Individual scientists have theories about the cause(s) of the pause. But there is as yet no consensus on this. See for yourself by reading abstracts of (and links to) 37 articles describing of the major 12 theories about causes of the pause, many by leaders in this field.

Climate denial by Left & Right dominates the public debate.

Summary: One of the oddities in American politics is how Left and Right clearly see each others’ faults, but remain blind to their own similar faults. The mainstream media reports the follies of the Right, but less often those of the Left — which are highlighted by their increasing abandonment of science in their quest to alarm the public about climate change. For example, their long effort to hide climate scientists’ work about the pause in warming of their atmosphere since roughly 2000. It’s a kind of denial, much as we see on the Right.

“… first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.” — Matthew 7:5.

Global Surface Temperature

Observed (black) and predicted (blue) global average annual surface temperature difference relative to 1981-2010. Previous predictions starting from November 1960 are in red, and 22 model simulations from the Coupled Model Intercomparison Project phase 5 (CMIP5) are in green. Shading in red represents the probable range, such that the observations are expected to lie within the shading 90% of the time. The forecast (blue) starts from November 2014. All data are rolling 12-month mean values. The black line is from Hadley Centre, GISS and NCDC data. {Caption slightly edited}

Left and Right work to mislead us

During the past few years scores of polls attempted to find the source of the public’s polarized views about climate change. Perhaps there’s a simpler answer. One group knows about the pause, and so has skepticism (for some grossly exaggerated) about the certainty of catastrophic future warming. The other group reads only activists and so remains ignorant of scientists’ research about the pause. For example, Joe Romm at ThinkProgress and Phil Phait in November 2013 and  February 2014 (he’s slacked off lately).

Climate scientists speak, even if we don’t listen

Meanwhile climate scientists continue their work, while Left and Right distort their findings to manipulate public opinion. As we see in the new “Decadal Forecast” of the UK Met Office. From the summary:
