Global Science Report: Hypotheses Masquerading as Facts in Federal Report on Climate Change Impacts in the U.S.

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.”

However, in addition to some very wet periods, the [Southeast] region has also experienced periods of extreme drying.
- U.S. Global Change Research Program, 2014

The quote above is from the 2014 federal report, Climate Change Impacts in the United States, Southeastern Region. Given the title and the subject, one would have to conclude that our government is telling us that this is a result of climate change.

“Authoritative” documents such as this often wind up in legal proceedings, as the “science” backup for proposed regulations. As such, statements of this ilk should be based upon some semblance of reality.

We find that many of these “factuals” are indeed subject to test. The one above is yet another assertion that climate change, presumably caused by emissions of carbon dioxide, is the cause of an increase in the frequency or severity of “extreme” events.

Floods and droughts qualify. After all, a flood is merely a cases of extreme high streamflow, and a prolonged drought will result an extreme low. Further, it is hard to find any weather extreme, any hurricane, tornado or wildfire where some apparent authority finds a television camera and does not blame it on global warming.

More Fun with Not-so-Dumb Organisms and the U.S. National Assessment of Climate Change

Last time around, we brought forth evidence against organismal “dumbness”—the notion that species found only in defined climatic environments will go extinct if the climate changes beyond their range. We picked on cute little Nemo, and “found,” much like in the animation, that his kind (Amphiprion ocellaris) could actually survive far beyond their somewhat circumscribed tropical reef climate.

The key was the notion of plasticity—the concept that, despite being linked to a fixed genetic compliment, or genotype, the products of those genes (the “phenotype”) changed along with the environment, allowing organisms some degree of insurance against climate change. How this comes about through evolution remains a mystery, though we may occasionally indulge in a bit of high speculation.

“Science,” according to the late, great philosopher Karl Popper, is comprised of theories that are capable of making what he called “difficult predictions.” The notion that gravity bends light would be one of those made by relativity, and it was shown to be true by Sir Arthur Eddington in the 1919 total solar eclipse. It just happened to be in totality in the Pleiades star cluster (also the corporate logo of Subaru), and, sure enough, the stars closest to the eclipsed sun’s limb apparently moved towards it when compared to their “normal” positions.

So we have been interested in a truly difficult test of phenotypic plasticity, and we think we found one.

How about a clam that lives in the bottom of the great Southern Ocean surrounding Antarctica? Specifically, the burrowing clam Laternula elliptica. According to a recent (2017) paper by Catherine Waller of the University of Hull (in the, perhaps temporarily, United Kingdom) “75 percent of the recorded specimens [of L. elliptica] are from localities shallower than 100 m,” where the populations are exposed to “low and stable water temperatures in the range of -1.9 to +1.8 °C” (the remaining 25 percent inhabit cooler waters of the continental slope down to ~700m).

You Ought to Have a Look: The Catastrophe of Climate Catastrophizing and Fun at the House Science Committee

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 time around You Ought to Have a Look at a brilliant analysis of the profound illogic of “climate catastrophizing” appearing, in all places, in Foreign Affairs, arguably the most important international contributor to precisely just that.

Written by the Manhattan Institute’s Oren Cass (“he’s just like you and me, only smarter”), who often finds himself YOTHALed in these writings, it’s a logical tour-de-force that skewers the exaggerated bathos of the apocalyptics with simple economic logic and hard numbers. Along the way, the usual purveyors of gloom-and-doom, like Stanford’s Paul Ehrlich and The Club of Rome, as well as some more modern-day would-be autocrats like Harvard’s Daniel Schrag, fall victim. The intellectual carnage wrought by Cass is truly breathtaking. And it’s all in Foreign Affairs.

Cass starts off with a bang:

Climate change may or may not bear responsibility for the flood on last night’s news, but without question it has created a flood of despair. Climate researchers and activists, according to a 2015 Esquire feature, “When the End of Human Civilization is Your Day Job,” suffer from depression and PTSD-like symptoms. In a poll on his Twitter feed, meteorologist and writer Eric Holthaus found that nearly half of 416 respondents felt “emotionally overwhelmed, at least occasionally, because of news about climate change.” 

For just such feelings, a Salt Lake City support group provides “a safe space for confronting” what it calls “climate grief.”

Panicked thoughts often turn to the next generation. “Does Climate Change Make It Immoral to Have Kids?” pondered columnist Dave Bry in The Guardian in 2016. “[I] think about my son,” he wrote, “growing up in a gray, dying world—walking towards Kansas on potholed highways.” Over the summer, National Public Radio tackled the same topic in “Should We Be Having Kids In The Age Of Climate Change?” an interview with Travis Rieder, a philosopher at Johns Hopkins University, who offers “a provocative thought: Maybe we should protect our kids by not having them.” And Holthaus himself once responded to a worrying scientific report by announcing that he would never fly again and might also get a vasectomy

Cass then notes that this fear is stoked at the highest levels, with gaudy statements by President Obama (as long as there’s no chance of an audience question, he notes), Hillary Clinton, Bernie Sanders, and Bill di Blasio (the last made at the Vatican, which has also been fanning the flames).

A True Fish Story: Adaptive Responses to Global Warming

The simplistic notion that organisms are “dumb” when it comes to changing environments goes like this: Species X lives in a relatively stable environment and with a certain defined range of temperature. So, if the temperature changes enough, species X will go extinct.

In resuming our series on biological adaptation to environmental change, we are going to be looking in depth at the evolutionary and environmental nuances that—with some limits—invalidate the simple point of view. And, in doing so, we will discover important implications for environmental and climate-related policies.

We begin with revolutionary classic in evolutionary biology published in 1984 by Peter Hochachka and George Somero called “Biochemical Adaptation.” It summarized and expanded on much of their earlier work on what they called “phenotypic plasticity”.

Natural Variability’s Role in Arctic Sea Ice Decline Strengthens Case for Lukewarming

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 “Current Wisdom.”

A story this week that has been making the rounds in the climate-media complex finds that natural variability is responsible for perhaps as much as 50% of the summertime decrease in Arctic sea ice that has taken place over the past 30 years or so (anthropogenic climate change is the presumed factor in the remainder).

This isn’t new. The last (2013) science report from the UN’s Intergovernmental panel on climate change said:

Using climate model simulations from the NCAR CCSM4…inferred that approximately half (56%) of the observed rate of decline from 19979 to 2005 was externally (anthropogenically) forced, with the other half associated with natural internal variability.

Ten years ago, a study was conducted by a team led by Julienne Stroeve that looked at the observed rate of Arctic sea ice loss and compared it to climate model expectations. [A side note here: the loss of Arctic sea ice (which is floating ice) does not lead to sea level rise just as the melting of ice in your cocktail doesn’t lead to your glass overflowing]. What Stroeve and colleagues found was the Arctic sea ice was being lost at a far brisker pace than climate models had predicted (Figure 1).

You Ought to Have a Look: Interview with Will Happer

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.

In a bit of a departure from our typical YOTHAL recipe, where we highlight three or four items from around the web that we found worthy of recommending to you for additional scrutiny, this week we highlight just a single, albeit somewhat lengthy, article that we feel is worth dedicating your time to. The article takes the form of an in-depth interview with Dr. William Happer, emeritus Department of Physics professor at Princeton University (and Cato Adjunct Scholar). It was conducted by TheBestSchools.org as part of their “Focused Civil Dialogues” series, with the topic being global warming. Although the interview was conducted last summer, it has received renewed attention lately as Happer’s name has come up as a good choice for President Trump’s science advisor. It is therefore a good example of the kind of tone that the incoming Administration could set on the topic of human-caused climate change.

During the interview, TheBestSchools and Happer work through the flow chart below, from top to bottom. Each step along the way, including the introduction featuring Happer’s personal history and accomplishments, is an interesting read featuring numerous anecdotes to back his well-thought out and thorough reasoning on why carbon dioxide emissions should not be vilified or regulated (at the same time being an ardent supporter of government actions to restrict/reduce real forms of pollution). The interview exudes history, including historical examples of the dangers and downfalls of political intervention in science and restrictions placed on scientific inquiry.

You Ought to Have a Look: How to Properly Worry about Climate Change, aka, Lukewarming

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.

In our last episode of You Ought to Have a Look (which was prominently quoted in an editorial in Nature magazine this week), we looked at reasons why folks who are wishing climate change mitigation should be the driving force behind most federal regulations should be very worried about what the incoming Trump Administration has in store. Most of his announced agency heads, etc., don’t share their vision (unlike those currently running the Obama Administration).

This week we start off with a guide to how folks should worry about climate change in general. Is it really true that, according to President Obama, “No challenge—no challenge—poses a greater threat to future generations than climate change”? The short answer is no. The long answer is provided by Manhattan Institute’s Oren Cass is his recent piece for National Affairs called “How to Worry about Climate Change”.

Oren describes how climate change is different from typical political policy questions:

Climate change is a different kind of problem from health-care reform, gender equality, or almost any traditional subject of political attention and action. Its relevant effects are still decades or centuries away. Scenarios with the most extreme effects, rather than the most likely ones, provide the sense of urgency and the rationale for policy responses. Those extreme outcomes are often distant ripples from the initial effect of a warmer climate, transmitted outward through multiple steps of causation and combined with other factors to produce or amplify the damage. By the time actual impacts arrive, the time for action may have long passed. But if climate change is not a typical policy problem, how should policymakers approach it?

…Yes, climate change is a problem. But what kind of problem?

He then sets out to answer that question:

Climate change—forecasted, irreversible, and pervasive—might therefore be called a “worrying problem.” Here, “worrying” does not mean “concerning” (though it is that as well), but rather something tailor-made for worry. Its effects exist primarily in the imagination and have poorly defined bounds that encourage speculation; a point of no return looms. Yet the contours of those bounds and that point may become clear only after it is too late to correct course.

Other worrying problems exist. They tend to emerge where clear long-term trends in technological or social change produce concerning side effects.

Oren provides other examples of “worrying problems” such as a global pandemic caused by international travel and urbanization, overuse of antibiotics, nuclear weapons, interconnectivity of financial systems, democratization of communications technologies, computer viruses, superhuman computer intelligence, weaponized nanotechnology, and many more, including social ones, as well as the sustainability of the Western welfare state itself. As Oren says there is “much to worry about,” but reminding everyone that “we should heed the well-known warning: ‘What worries you masters you.’”
