CO2 Regulation News from the Federal Register

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.”

The Federal Register has been brimming with announcements of government activities aimed to reduce/regulate carbon dioxide emissions emanating from the United States.

You may wonder why the government finds the need to pursue such action since 1) U.S. carbon dioxide emissions have already topped out and have generally been on the decline for the past 7-8 years or so (from technological advances in natural gas extraction and a slow economy more so than from already- enacted government regulations and subsidies); 2) greenhouse gases from the rest of the world (primarily driven by China) have been sky-rocketing over the same period, which lessens any impacts that our emissions reduction have); and 3) even in their totality, U.S. carbon dioxide emissions have a negligible influence on local/regional/global climate change (even a immediate and permanent cessation of all our carbon dioxide emissions would likely result in a mitigation of global temperature rise of less than one-quarter of a degree C by the end of the century).

We wonder the same thing. Nevertheless, the government has lots of ideas for how to save ourselves from ourselves (with likely to opposite outcome).

Here is a summary of new announcements appearing in the Federal Register over the past month or so on actions aimed to curtail our carbon dioxide emissions (primarily the result of our desire for cheap and reliable energy—gasp!).

Posted November 26, 2013: The Office of Management and Budget (OMB) announced a call for review of the Technical Support Document currently justifying the Administration’s value of the social cost of carbon (SCC) used in federal cost/benefit analyses.  We have discussed this announcement previously, and while it provides a glimmer of hope for injecting some new science and common sense into the government’s social cost of carbon, we are highly skeptical of a positive outcome. We mention the announcement again here, because the public comment period ends on January 27, 2014.  Comments can be submitted here.

Posted December 6, 2013: The Department of Energy announced another in its seemingly endless string of intrusions into our personal choices through its energy efficiency requirement updates for all sorts of consumer products. These revised efficiency regulations rely on the SCC to offset the costs and enrich the apparent benefits of the new requirements. We have already submitted comments on several of these proposed regulations (from walk-in refrigerators to furnace fans), but they just keep on coming.  The latest pertains to commercial and electric motors. Final comments are due February 4, 2014 and con be submitted here.

Posted December 31, 2013: The Department of Energy (DoE) announced that it has declined a Petition for Reconsideration of its rule updating the energy conservation standards for of microwave ovens.  The Petition for Reconsideration was brought by the Landmark Legal Foundation which pointed out that the DoE used a social cost of carbon estimate in the cost/benefits analysis for the rule that had not been subject to public comment and which was some 50% higher than the value used in the C/B analysis that was available for public comment.  In other words, the DoE pulled a pretty big bait and switch.  We at the Cato’s Center for the Study of Science submitted comments on the Landmark Petition pointing out just how far afield from the actual science that the Administrations SCC estimate had become.  The denial was disappointing, but the fight over the proper value for the SCC has now moved to the OMB (as described above).

‘Worse Than We Thought’ Rears Ugly Head Again

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.”


Our last post was a brief run-through of some items of interest from the recent scientific literature that buck the popular alarmist meme that human-caused climate change is always “worse than we thought.” But as we said in that post, finding coverage of such results in the dinosaur media is a fool’s errand. Instead, it thrives on “worse than we thought” stories, despite their becoming a detriment to science itself.

Not to disappoint, headlines from the first major climate change story of the new year claim “Climate change models underestimate likely temperature rise, report shows,” and it’s clearly Worse Than We Thought. In its January 5 (Sunday) paper, the editorial board of the Washington Post points to the new results as a call for action on climate change.

The trumpeted results appear in a paper published in the January 2nd 2014 issue of Nature magazine by a team led by University of New South Wales professor Steven Sherwood and colleagues which claims that the earth’s equilibrium climate sensitivity—how much the global average surface temperature will rise as a result of a doubling of the atmospheric carbon dioxide content—is being underestimated by most climate models. Sherwood’s team finds “a most likely climate sensitivity of about 4°C, with a lower limit of about 3°C.”

Sherwood’s most likely value of 4°C is about twice the value arrived at by a rather largish collection of other research published during the past 2-3 years and lies very close to the top of the likely range (1.5°C to 4.5°C) given in the new report from the U.N.’s Intergovernmental Panel on Climate Change (IPCC).

While there are a host of reasons as to why our understanding of the true value of the climate sensitivity is little better constrained now that it was some 20+ years ago (it was given as 1.5°C to 4.5°C in the IPCC’s first report issued, almost a quarter-century ago), it is widely recognized that our understanding of the role of clouds in a changing climate is central to the issue.

In describing the why climate models have such different climate sensitivity values, the IPCC writes, in the 2013 edition of it’s science compendium,

There is very high confidence that uncertainties in cloud processes explain much of the spread in modelled climate sensitivity.

Sherwood and colleague set out to see if they could help nail down the specific cloud processes involved in the model spread and to see if recent observations could help better understand which models were handling  processes related to cloud behavior better than others.

Spreading Some Holiday Cheer: Global Warming Not Always ‘Worse Than We Thought’

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.”

We know this: Every holiday season some of our readers make some offhanded comment at a party, to the effect that, well, global warming (or its effects) appear to have been a bit overblown. Before you finish, you’re likely to be assaulted by a sharp ranch dressing-laden carrot stick or you might get a face full of dill-dipped broccoli.

Fight back! Before things escalate to the level of food assaults, trot out some of the facts in this, our annual guide for holiday parties.

First of all, the tendency for prominent findings about the impacts from human-caused global warming to be “worse than we thought” is not only a pure play for press coverage, but also strains, if not obliterates, scientific credibility.

The unscientific preponderance of “worse than we thought” stories is starting to become more widely recognized (although we have been talking about it for years). And it is having consequences. Fresh from accepting his Nobel Prize for physiology/medicine, University of California’s Randy Schekman announced that his lab would no longer be sending any research papers to “luxury journals” like Science and Nature because of their preference to select papers “that will make waves because they explore sexy subjects.” Schekman explains that “These journals aggressively curate their brands, in ways more conducive to selling subscriptions than to stimulating the most important research.” Global warming alarmism is a prime example of this.

In fact, there are scientific studies that conclude that things aren’t likely to be worse than we thought, but looking to the “luxury journals” or to the press to highlight them is a fool’s errand.

But that’s where we can help!

In the spirit of this season of good cheer, and as a respite for the increasing number of those out there suffering from “apocalypse fatigue,” your obedient servants at the Center for the Study of Science are here to bring you a little holiday joy and good news.

Below, we’ve collected some clips and quips culled from the recently published scientific  literature (and observations) that show that perhaps the impacts from climate change resulting from our production of energy from fossil fuels isn’t going to worse than we thought—and, in fact, may not prove to be so bad at all.

How Offal! Global Warming Threatens the World’s Haggis Supply!!

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.” In this edition, we cover an important story that we missed back in 2008.

People send us stuff. As a result of our recent Global Science Report on global warming ruining our bananas, one of our fans directed our attention to an important effect of climate change that we somehow missed, back in 2008, when the alarmists at the BBC wrote that it was threatening haggis.

Haggis, for the uninitiated, is sheep stomach stuffed with minced lung, liver, heart, tongue, suet, onions and oats. How offal!

While there’s no accounting for taste, it tastes as bad as it smells.

According to the story, there has been a rise in a parasite effecting Scottish sheep that renders the lung “unfit for consumption” (something that many of you probably thought was the case already).

And, so as not to miss the bandwagon, an official from the Scottish Agricultural College Veterinary Investigation Centre told the BCC that:

Part of the reason will be the parasite is able to live a pretty happy life on the ground because of higher temperatures. Maybe it’s climate change.

Or maybe not.

It turns out that another potential cause of the increase in the lung parasite is that Scottish farmers have reduced their application of parasite treatment due to declining infections of roundworm. The treatment of roundworm also killed the lung parasite.

There was no mention made in the BCC article as to whether global warming was behind the decrease in roundworm infestations.

Instead, the article went on the describe the events which took place in the World Haggis Eating Championship, won by Willie Robertson from Dunkeld, who managed to put away a pound of haggis in 125 seconds. For his victory, Mr. Robertson was awarded a trophy and a bottle of whiskey—no doubt a key feature in the rest of the day’s merrymaking.

BBC’s writing in the haggis story appears similarly merry. Here are the last three paragraphs of their report, verbatim, a candidate for first place in the 2008 International Nonsequitur Competition.

The championship was held as part of the 125th Birnam Highland Games, and attracted competitors from Australia, New Zealand and the US.

Climate change, meanwhile, has been blamed for affecting natural habitats in Scotland and across the world.

Most notably, scientists and conservationists say it threatens survival of polar bears.

Going Bananas: Another Climate Change Hustle

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.”

We hear that there is looming banana crisis in Costa Rica—the world’s 2nd leading exporter of the fruit—as this year’s crop is being threatened by an infestation of mealybugs, scale insects, and fungal infection.

Petulance, plagues, disease? It must be climate change, of course!

The Director of the Costa Rican Agriculture and Livestock Ministry’s State Phytosanitary Services, Magda González, told the San José Tico Times, “Climate change, by affecting temperature, favors the conditions under which [the insects] reproduce.” González estimated that the rising temperature and concomitant changes in precipitation patterns could shorten the reproduction cycle of the insect pests by a third. “I can tell you with near certainty that climate change is behind these pests.”

This is bananas.

But there’s a method to Gonzalez’ madness.  In it’s recent Warsaw confab on climate change, the UN has made it abundantly clear that one of its endgames is compelling “reparations” for climate damages cost by dreaded emissions of carbon dioxide.  The more that poorer nations make these claims—however fatuously—the more momentum builds to extract capital from me and thee.

May we humbly suggest that calling Ms. Gonzalez’ claim “fatuous” is really being too nice.  She should actually propose compensating the United States for all the excess bananas that are associated with warmer temperatures.

Figure 1 shows banana production in Costa Rica from 1961-2011. Figure 2 shows the temperatures there over the same period. We hate to burst anyone’s climate-change-is bad-bubble, but the correlation between these two variables is positive. That is, higher temperatures are associated with greater banana production (and yield).

  

 Figure 1. Annual production (tonnes) and yield (Hg/Ha) of bananas in Costa Rica (data from FAOSTAT)

 

Figure 2. Annual temperature anomalies in Costa Rica, 1961-2011 (data from Berkeley Earth).

And as far as precipitation goes, the trends down there are all over the place—some stations show trends towards increasing rainfall amounts, while others nearby, towards decreasing amounts.  The geography of the country, along with all sorts of external influences including tropical cyclone activity, sea surface temperature patterns, and larger-scale circulation systems in both the Pacific and Atlantic makes for a very complex pattern precipitation variability, both temporally and spatially, across Costa Rica.  It is virtually impossible to assess the influence of recent human-caused climate change in such a complicated and highly variable natural system.

So you have a situation where annual precipitation variability is high and where warmer conditions seem to be associated with greater banana yields. 

While it is probably not out completely out of the question that some sort of weather influence may, in part, play some role in the current affliction of the Costa Rica banana crop, to implicate human-caused global warming, you’d have to have gone completely…, well, you know.

But climate policy has always functioned best in a data-free environment, about the only way a cheap hustle like that of the Costa Rican National Phytosanitariest merits any attention at all.

2013: Will U.S. Temperature Be Below Average?

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.”


Last year, the annual average temperature in the contiguous United States was the highest on record (since 1895) according the data compiled by the National Climatic Data Center (NCDC).   This year, the temperature took a nosedive from the lofty heights of 2012.

As we pointed out in our coverage of the 2012 milestone, the influence of human-caused climate change on the U.S. temperature history (including last year’s record warmth), while undoubtedly present, is difficult to ascertain.

The role that anthropogenic “global warming” from the emissions of greenhouse gases from the combustion of fossil fuels plays is debatable—both in timing and magnitude. Almost certainly its influence is present and detectable in the U.S. annual average temperature record, but beyond that simple statement, not a whole lot more can be added with scientific certainty.

We now stand nearly a year later with more evidence of proof and point.

Through November of this year, the U.S. average temperature is only 0.53°F above the 20th century mean temperature (the default baseline used by NCDC). Last year the annual temperature was 3.24°F above it.

Figure 1. Average January-November temperature in the contiguous United States from 1895-2013 as compiled by the National Climatic Data Center (source: NCDC, Climate at a Glance).

With the cold start to December across the country, the annual temperature for 2013 has an increasingly good shot at coming  in below the 20th century average.  For this to happen, the U.S. temperature for December would have to average about 27.6°F. For the first 12 days of the month, the average has been 28.4°F,  and the forecast is for continued cold, so getting to the needed temperature is not out of the question.

If 2013 does come in below the 20th century average, it would be the first year since 1996 to have done so, and would end a 16-year long run of above average annual temperature for the U.S.  You can follow the chase here.

But even if the rest of the month is not quite cold enough to push the entire year into negative territory, the 2013 annual temperate will still be markedly colder than last year’s record high, and will be the largest year-over-year decrease in the annual temperature on record, underscoring the “outlier” nature of the 2012 temperatures.

Will 2013 mark the end of the decade and a half period of abnormal warmth experience across the U.S. that was touched off by the 1998 El Niño event, and a return to conditions of the 1980s and early-to-mid 1990s? Or will 2013 turn out to just be a cold blip in the 21st century U.S. climate?

In either case, 2013 shows that the natural variability of annual temperatures in the U.S. is high (as is decadal and multi-decadal variability, see Figure 1)—an important caveat to keep in mind when you face the inundation of every-weather-event-is-caused-by-human-global-warming hysteria.

Stay tuned!

The Center for the Study of Science would like to thank Ryan Maue of WeatherBELL Analytics for his summary of December temperatures and the expected  temperatures for the rest of the year.

High-profile Paper Linking GMO Corn to Cancer in Rats Retracted

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.”

 

About a year ago, a major paper appeared in a high-profile scientific journal, Food and Chemical Toxicology, claiming a link between genetically modified corn and cancer in rats. The findings were published by a research team led by Gilles-Éric Séralini of the University of Caen in France. It was widely trumpeted by people opposed to genetically modified organisms (GMOs).

Simply put, making a GMO dramatically accelerates the normally slow process of traditional plant breeding, which takes many generations to stabilize some desired new trait in the plant genome, making the philosophical objections to it seem somewhat naïve.

While Séralini’s finding was heralded by anti-GMO activists as an “I told you so,” the paper was promptly, harshly, and widely criticized by geneticists and the general scientific community, many of whom lobbied the journal directly to address the shortcomings in the paper.

The most stinging criticism is going to sound painfully like what we see so often in environmental science, where researchers purposefully design an experiment likely to produce a desired results. Two months ago we documented a similar process that pretty much guaranteed that the chemical currently the darling of green enrages, bisphenyl-A, would “cause” cancer.

In Seralini’s case, the research team used a strain of rats with a known strong proclivity to develop cancer if left to age long enough, which is what they allowed, obeying the maxim that “if you let something get old enough, it will get cancer.”
