You Ought to Have a Look: Lukewarming, Carbon Taxes, and the HFC Agreement

You Ought to Have a Look is a regular feature from the Center for the Study of Science.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic. Here we post a few of the best in recent days, along with our color commentary.

One of our favorite lukewarmers, Matt Ridley, was invited by the Global Warming Policy Foundation to give its 2016 Annual Lecture. He certainly did not disappoint. While Matt titled his speech “Global Warming Versus Global Greening” that title only suggested part of what he had to say. We offer “The Hows and Whys of Lukewarming” to be a more apt descriptor:

These days there is a legion of well paid climate spin doctors. Their job is to keep the debate binary: either you believe climate change is real and dangerous or you’re a denier who thinks it’s a hoax.

But there’s a third possibility they refuse to acknowledge: that it’s real but not dangerous. That’s what I mean by lukewarming, and I think it is by far the most likely prognosis.

I am not claiming that carbon dioxide is not a greenhouse gas; it is.

I am not saying that its concentration in the atmosphere is not increasing; it is.

I am not saying the main cause of that increase is not the burning of fossil fuels; it is.

I am not saying the climate does not change; it does.

I am not saying that the atmosphere is not warmer today than it was 50 or 100 years ago; it is.

And I am not saying that carbon dioxide emissions are not likely to have caused some (probably more than half) of the warming since 1950.

I agree with the consensus on all these points.

I am not in any sense a “denier”, that unpleasant, modern term of abuse for blasphemers against the climate dogma…. I am a lukewarmer.

And from there, Ridley goes on to do a laudable job of laying out the case that future climate change from human activities will prove to be towards the low end of climate model projections—but squarely within the bounds of consensus expectations. As Matt puts it:

…I am not disagreeing with the consensus on climate change.

There is no consensus that climate change is going to be dangerous. Even the IPCC says there is a range of possible outcomes, from harmless to catastrophic. I’m in that range: I think the top of that range is very unlikely. But the IPCC also thinks the top of its range is very unlikely.

Be sure to check out the whole thing for a great review of why carbon dioxide emissions are not the civilization-ending monster that many climate activists would have you believe (plus there are a few surprises in there that you won’t want to miss).

You Ought to Have a Look: Misleading Storylines and False Beliefs Lead to Poor Policy

You Ought to Have a Look is a regular feature from the Center for the Study of Science.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary. 

We highlight this week a collection of items which have a common thread—poorly informed beliefs lead to poorly formulated policy. And poorly formulated policy is worse than no policy at all.

For starters, consider this article by Cato senior fellow Johan Norberg, in support of his new book, Progress: Ten Reasons to Look Forward to the Future. Writing in CapX, Norberg looks at the reasons “Why are we determined to deny that things are getting better?” He points to how the media, in combination with our own psychological tendencies, lead us to the false assumption that the state of the world is declining, when in fact, trends are overwhelmingly in the other direction. Norberg points out that there is a danger in our misperception, “People led by fear risk curtailing the freedom that progress depends on.”

Here are some expects from his article:

A couple of years ago, I commissioned a study in which 1,000 Swedes were asked eight questions about global development. On average, every age group and every income group was wrong on all eight questions – because they all thought the world was in bad shape and getting worse. Large majorities, for example, thought that hunger and extreme poverty have been increasing, when they have in fact been reduced faster than at any other point in world history. And those who had been through higher education actually had less knowledge than the rest.

It’s not just Sweden. In Britain, only 10 per cent of people thought that world poverty had decreased in the past 30 years. More than half thought it had increased. In the United States, only 5 per cent answered (correctly) that world poverty had been almost halved in the last 20 years: 66 per cent thought it had almost doubled.

Why do we make these false assumptions? Many of them are formed by the media, which reinforces a particular way of looking at the world – a tendency to focus on the dramatic and surprising, which is almost always bad news, like war, murder and natural disasters.

…[P]eople led by fear might curtail the freedom and the openness that progress depends on. When Matt Ridley, author of The Rational Optimist, is asked what he is worried about, he usually responds “superstition and bureaucracy”, because superstition can obstruct the accumulation of knowledge, and bureaucracy can stop us from applying that knowledge in new technologies and businesses.

Johan’s full article, along with his new book, are well worth the taking the time to explore. A good place to start is this Cato book series event, where you can listen to Johan talk about his viewpoint and describe his findings.

Read All About It! Heat Dries Things Up!

Global Science Report is a feature from the Center for the Study of Science, where we highlight one or two important new items in the scientific literature or the popular media. For broader and more technical perspectives, consult our monthly “Current Wisdom.”

No one doubts that much of the West, especially California, has been very droughty since the turn of the century, and that heat and drought are highly correlated. So it seemed surprising that it was big news last week that forest fires, which require dry fuel, are on the increase out there.

University of Idaho’s John Abatzoglou and Columbia’s A. Park Williams used a large family of climate models to calculate various indices of western aridity (they used eight different measures), which were then related to the burned-out area every year. About half of the increase since the mid-1980s was related to climate-modelled warming. The other half, they say, was from other causes, including natural variability. The authors also note that some forest management practices may be contributing to the increasing burn.

The notion that this much drying is caused by dreaded global warming is what made the papers.

Should we use models that can’t even get close to the real-world evolution of lower atmospheric temperatures in recent decades to determine how much climate change is human-caused? That’s what they did—assuming only warming that was not modelled was “natural.” To say the least, that’s a heavy logical lift when it is so clear that the models are predicting far too much warming in the lower layers.

It is all too human to not let some else’s work get in the way of your confirmation bias. So there’s no mention of another explanation for why it’s so hot and dry there. Writing in the same journal that the fire work was published in, the Proceedings of the National Academy of Sciences (PNAS), two other western researchers, James Johnstone and Nathan Mantua, demonstrated that virtually all of the temperature changes in California and the West are related to changes in atmospheric pressure patterns that occur with or without global warming. That was first published in 2014, but there is no reference to it whatsoever in the fire paper. 

Nor is there any reference to the most comprehensive study of western fires—some 33,000 of them—by Argentina’s Thomas Kitzberger showing that for centuries the distribution and frequency of western fires is related to well-known atmospheric patterns over  both the North Pacific and North Atlantic, not global warming. It too was published in PNAS, in 2007.

But we digress. Aridity is largely driven by temperature (warmth) and precipitation. Unfortunately, only two of their eight measures of dryness are very sensitive to rainfall variability.

Climate models have pretty much no skill in estimating precipitation. But they do predict warming, and western (particularly California and Arizona) temperatures are higher than they were. So, absent any precipitation data, they are guaranteed to paint a drying picture and therefore an increase in fire extent.  

The six aridity indicators that are not particularly influenced by precipitation instead are primarily temperature-driven. Not surprisingly, these show much greater increases in aridity than the other two.

Here’s an example from the heavily forested northwest states of Idaho, Washington and Oregon. One of the aridity indicators is the Palmer Drought Severity Index (PDSI), an old warhorse that has been used to assess long-term moisture status since it was first published in 1965 by Wayne Palmer, a scientist at the (then) U.S. Weather Bureau. 

You Ought to Have a Look: Big Science, Carbon Taxes, and the Clean Power Plan’s Day in Court

You Ought to Have a Look is a regular feature from the Center for the Study of Science.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary.

This week we feature a few smart pieces by some smart folks.

First up is an excellent post “Climate Modeling: Settled Science or Fool’s Errand?” by Competitive Enterprise Institute’s Bill Frezza in which he discusses the development of climate models and the reliability of the future that they project. But Bill’s post is really just to provide some background for his Real Clear Radio Hour interview with Arizona State University’s Dr. Daniel Sarewitz, who is the co-director of ASU’s Consortium for Science, Policy, and Outcomes. Sarewitz has a lot of interesting things to say about “Big Science” and the problems that result. Frezza summarizes his interview:

Sarewitz, who was trained as an earth scientist, is terrified that “science is trapped in a self-destructive vortex” that is endangering both science and democracy. In his blockbuster analysis mentioned above, he nails his thesis to the laboratory door, challenging Big Science to get its act together. Politicizing science, he argues, leads to debates about science being substituted for debates about politics. So we end up fighting over unverifiable forecasts about what might happen in the future, rather than wrestling with the complex tradeoffs that attend political decisions on what we should – or could – do about carbon emissions under all the potential future scenarios.

But rather than get discouraged, Sarewitz believes there is a way out of this conundrum. His advice is, “Technology unites while science divides.” He recommends that science “abdicate its protected political status and embrace both its limits and its accountability to the rest of society.” Despite calling long-range climate forecasting “a fool’s errand,” he thinks dumping too much CO2 in the atmosphere will make anthropogenic global warming a long term problem that will eventually require the decarbonization of our energy industries. But he sees this as a process taking many decades, one that can be best addressed not with politicized science, but by letting adaptation, innovation, wealth creation, and economic growth lead the way.

If you have a free 20 minutes or so and are interested in how the quest for policy has derailed the pursuit of science, listening to Frezza’s full Sarewitz interview will be time well spent.

Statement on the Ratification of the Paris Agreement

Earlier this afternoon in the Rose Garden, President Obama celebrated the ratification of the Paris Agreement. I had this to say in response:

President Obama was a bit less than candid in his speech about the adoption of the U.N.’s Paris Agreement. Using realistic assumptions about role of carbon dioxide in climate change, the Agreement will prevent 0.1 to 0.2°C of global warming by the year 2100, not the inflated figure the U.N. gets by assuming all warming since the Industrial Revolution is caused by human emissions of carbon dioxide. Few, if any, climate scientists would defend that. It also assumes that emissions will—without the Paris Agreement—increase much faster than the average increase used in climate simulations. In reality, the UN’s own Climate Panel states only that carbon dioxide is causing more than 50% of the warming observed since 1950, not 1800. Further, the switch from coal to natural gas for electrical generation has already invalidated the UN’s assumptions about the growth of atmospheric carbon dioxide.

He is also a bit optimistic about China, which has said it will stop increasing carbon dioxide emissions “around” 2030. This is exactly the time that researchers in Obama’s own Department of Energy said, in 2011, that their emissions would level off due to their maturing economy, and without any explicit policy to reduce greenhouse gas emissions, best known as “business as usual.”

You Ought to Have a Look: Close-hold Embargos, Scientific Outsiders, and Activists Behaving Badly

You Ought to Have a Look is a regular feature from the Center for the Study of Science.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary. 

With last week’s news dominated by the debates—both in front of the American people (Trump v. Clinton) and in front of the American courts (West Virginia v. EPA)—we figured we’d highlight a couple of other stories that may have not have gotten the attention that they deserved. 

First up is a piece that left us slack-jawed. “How the FDA Manipulates the Media” is an investigative journalism article Charles Seife of Scientific American that reveals a seamy world of backroom press manipulation by scientific bodies (in this case, the federal Food and Drug Administration) through a practice known as a close-hold embargo. While some organizations, including major scientific journals like Science and Nature, employ an embargo system that allows some members of the press access to articles before they are officially “published” so that they can prepare news stories, the only condition is that no one releases the story before a set date. This is why a bunch of news stories, all covering the same piece of scientific information, all hit the airwaves/intertubes at the same time.  While this type of embargo is a bit unfair to anyone who perhaps wants to comment on the story but is blindsided by it – the procedure only biased by the well-known predilections of the mainstream press.  However, the close-hold embargo is an (almost mythical) horse of a different color. Its intent is to generate loads of press, but only good press. 

Here’s a taste from Scientific American:

The deal was this: NPR, along with a select group of media outlets, would get a briefing about an upcoming announcement by the U.S. Food and Drug Administration a day before anyone else. But in exchange for the scoop, NPR would have to abandon its reportorial independence. The FDA would dictate whom NPR’s reporter could and couldn’t interview.

…This kind of deal offered by the FDA—known as a close-hold embargo—is an increasingly important tool used by scientific and government agencies to control the behavior of the science press. Or so it seems. It is impossible to tell for sure because it is happening almost entirely behind the scenes. We only know about the FDA deal because of a wayward sentence inserted by an editor at the New York Times. But for that breach of secrecy, nobody outside the small clique of government officials and trusted reporters would have known that the journalists covering the agency had given up their right to do independent reporting.

Documents obtained by Scientific American through Freedom of Information Act requests now paint a disturbing picture of the tactics that are used to control the science press. For example, the FDA assures the public that it is committed to transparency, but the documents show that, privately, the agency denies many reporters access—including ones from major outlets such as Fox News—and even deceives them with half-truths to handicap them in their pursuit of a story. At the same time, the FDA cultivates a coterie of journalists whom it keeps in line with threats. And the agency has made it a practice to demand total control over whom reporters can and can’t talk to until after the news has broken, deaf to protests by journalistic associations and media ethicists and in violation of its own written policies.

By using close-hold embargoes and other methods, the FDA, like other sources of scientific information, are gaining control of journalists who are supposed to keep an eye on those institutions. The watchdogs are being turned into lapdogs. “Journalists have ceded the power to the scientific establishment,” says Vincent Kiernan, a science journalist and dean at George Mason University.

And if you think this taste is bad, the whole article will make you ill. Sickening, but eye-opening. Perhaps take an alka seltzer first, but you really ought to have a look.

You Ought to Have a Look: The Interface of Climate Change Science and Climate Change Policy

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger.  While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic.  Here we post a few of the best in recent days, along with our color commentary.

We came across a pair of interesting, but somewhat involved reads this week on the interface of science and science policy when it comes to climate change. We’ll give you a little something to chew on from each one, but suggest that you ought you have a look at them at length to appreciate them in full.

First up is a piece, “The Limits of Knowledge and the Climate Change Debate” appearing in the Fall 2016 issue of the Cato Journal by Brian J. L. Berry, Jayshree Bihari, and Euel Elliott in which the authors examine the “increasingly contentious confrontation over the conduct of science, the question of what constitutes scientific certainty, and the connection between science and policymaking.”
