House Ag Democrats

For more than 185 years, the House Committee on Agriculture has established farm policy for agriculture and rural America in the nation’s capital. The responsibilities and goals of the House Committee on Agriculture are as diverse as the needs of American agriculture. We face issues as varied as renewable energy, rural development, nutrition, crop insurance, conservation, international trade, futures market regulation, animal and plant health, agricultural research and development, bioterrorism, forestry and many others.

Book review: Bad science and bad arguments abound in ‘Apocalypse Never’ by M ichael Shellenberger » Yale Climate Connections

Cornucopians, as in the ‘horn of plenty’ of Greek mythology, and Malthusians, as in Thomas Malthus, express competing world views.

A new book that critiques environmentalism is ‘deeply and fatally flawed.’

By Dr. Peter H. Gleick | Wednesday, July 15, 2020

hink, if you will, of the feud between the Montagues and the Capulets in “Romeo and Juliet.” Or of the 1863-1891 classic American feud between the Hatfields and the McCoys, warring families in West Virginia and Kentucky.

In the decades-old tensions involving environmental science, population, resource dynamics, and ecology, it’s the Malthusians and the Cornucopians. Subscribing to the wisdom of English economist Thomas Malthus, Malthusians express concerns that exponential human population growth and economic demands will outrun global resources needed to support people, undermining long-term sustainability. Cornucopians, in contrast – with their nod to the cornucopia or “horn of plenty” of Greek mythology – hold that technological advances can sustain societal needs and that unbounded economic growth and increased population are positive, giving rise to more good ideas.

Review

The historical tensions and intellectual debates between Malthusians and Cornucopians are now more than two centuries old and have evolved. In recent years, the public conversation around critical global crises like human-caused climate change, deforestation and species extinction, population pressures, and new and worsening public health threats has grown louder, harsher, and increasingly ideological. As the sciences have improved, the deep complexity and connections among these problems have also become more apparent, as have urgent calls to address them through local, national, and global actions.

A recent entry in this debate is Michael Shellenberger’s “Apocalypse Never: Why Environmental Alarmism Hurts Us All” (HarperCollins Publishers, 2020). Shellenberger explains in his introduction that he seeks to counter and dismiss what he considers irrational, overwrought arguments of pending Malthusian catastrophes; instead, he seeks to promote the Cornucopian view that environmental problems can be eliminated if we’d just pursue aggressive economic growth, simple technological advances, and increased tapping of abundant natural resources. In doing so, he echoes previous efforts of authors like Herman Kahn, Julian Simon, and Bjørn Lomborg.

Climate dialogue seen as ‘out of control’

Shellenberger self-describes as an environmentalist activist and a bringer of facts and science to counter “exaggeration, alarmism, and extremism that are the enemy of a positive, humanistic, and rational environmentalism.” He decided to write this book because he believes “the conversation about climate change and the environment has, in the last few years, spiraled out of control.”

Voices of reason and clear analyses in the contentious debates about how to tackle our global problems are welcome. Unfortunately, the book is deeply and fatally flawed. At the simplest level, it is a polemic based on a strawman argument: To Shellenberger, scientists, “educated elite,” “activist journalists,” and high-profile environmental activists believe incorrectly that the end of the world is coming and yet refuse to support the only solutions that he thinks will work – nuclear energy and uninhibited economic growth.

‘What is new in here isn’t right, and what is right isn’t new.’

But even if the author properly understood the complexity and nature of global challenges, which he does not, and got the science right, which he did not, a fatal flaw in his argument is the traditional Cornucopian oversimplification of his solutions – reliance on economic growth and silver-bullet technology. As the great American journalist and humorist H. L. Mencken said, “there is always a well-known solution to every human problem – neat, plausible, and wrong.” Mencken also warned against those who know precisely what is right and what is wrong, a warning especially worth hearing in the highly complex and uncertain worlds of global climate, pandemics, and environmental change.

… yet bad science, strawman arguments, cherry-picking facts, and ad hominem attacks on scientists, media, others

But the problems in the book go much deeper. The author wanders from topic to topic, jumping from personal anecdote to polemical arguments to data and numbers carefully chosen to support his views, making it difficult for the reader to follow his threads. The most serious flaw, however, is that he assumes a position and seeks data and facts to fit that position rather than, as science demands, using data and facts to develop, test, and refine a theory. As a result, the book suffers from logical fallacies, arguments based on emotion and ideology, the setting up and knocking down of strawman arguments, and the selective cherry-picking and misuse of facts, all interspersed with simple mistakes and misrepresentations of science. Distressingly, this is also an angry book, riddled with ugly ad hominem attacks on scientists, environmental advocates, and the media.

I provide just a few examples of these flaws here – a comprehensive catalog would require its own book. In short, what is new in here isn’t right, and what is right isn’t new.

Two Cornucopian ideas lie at the heart of this book: The first idea is that there are no real “limits to growth” and environmental problems are the result of poverty and will be solved by having everyone get richer. This idea isn’t original and has long been debunked by others (for a few examples see here, here, here, and here).

View that nuclear alone can address needs

The second idea – and the focus of much of Shellenberger’s past writings – is that climate and energy problems can and should be solved solely by nuclear power. He writes, “Only nuclear, not solar and wind, can provide abundant, reliable, and inexpensive heat,” and, “Only nuclear energy can power our high-energy human civilization while reducing humankind’s environmental footprint.” (“Apocalypse Never” – hereafter “AN” – pp. 153 and 278) The many economic, environmental, political, and social arguments levied against nuclear are simply dismissed as having no merit, for example: “As for nuclear waste, it is the best and safest kind of waste produced from electricity production. It has never hurt anyone and there is no reason to think it ever will.” (AN, p. 152) His passionate belief that nuclear is the only answer to our energy and climate problems (maybe along with a mega-dam on the Congo River in Africa) is matched by the corollary that renewable energy alternatives – he calls them “unreliables” (AN, p. 176) – are bad because he asserts they are small scale, intermittent, and their economic, environmental, political, and social problems disqualifying.

The argument that poverty and environmental threats are intertwined is both correct and not new. It lies at the heart of international development efforts, including the early United Nations Millennium Development Goals and the current Sustainable Development Goals, which state:

The Sustainable Development Goals are the blueprint to achieve a better and more sustainable future for all. They address the global challenges we face, including those related to poverty, inequality, climate change, environmental degradation, peace and justice. The 17 Goals are all interconnected. (emphasis added)

Similarly, mainstream experts in environmental science and environmental economics have long acknowledged that all energy options have complex sets of environmental advantages and disadvantages. The fields of energy risk assessment, integrated environmental systems analysis, and ecological economics have addressed them for decades.

Using the facade of ‘strawman arguments’

Shellenberger regularly sets up other strawman arguments and then knocks them down. [A strawman argument is an effort to refute an
argument that hasn’t been made by replacing your opponent’s actual
argument with a different one.] One of the most prevalent strawman arguments in the climate debate is that scientists claim climate change “causes” extreme events, when in fact, climate scientists make careful distinctions between “causality” and “influence” – two very different things. This area, called “attribution science,” is one of the most exciting aspects of climate research today.

Shellenberger sets up the strawman argument that people are incorrectly claiming recent extreme events (like forest fires, floods, heat waves, and droughts) were caused by climate change, and then he debunks this strawman. “Many blamed climate change for wildfires that ravaged California” (AN, p.2) and “the fires would have occurred even had Australia’s climate not warmed.” (AN p. 21) He misrepresents how the media reported on the fires, describing a New York Times story on the 2019 Amazon fires: “As for the Amazon, The New York Times reported, correctly, that the ‘fires were not caused by climate change.’” But here Shellenberger is cherry-picking a quote: If you look at the actual article he cites, the journalist makes clear the “influence” of climate change just two sentences later:

These fires were not caused by climate change. They were, by and large, set by humans. However, climate change can make fires worse. Fires can burn hotter and spread more quickly under warmer and drier conditions. (emphasis added)

He also misunderstands or misrepresents the extensive and growing literature on the links between climate change and extreme events, saying “But climate change so far has not resulted in increases in the frequency or intensity of many types of extreme weather” (AN, p. 15) citing out-of-date research, including a workshop from 15 years ago. In fact, a large and growing body of literature already shows strong links between climate change and extreme events, including hurricanes, heat deaths, flooding, decreasing ice, and more (see, for a few examples, here, here, and here), and this literature has been expanding rapidly. For instance, in 2019, the American Meteorological Society, or AMS, published a summary – produced annually – with 21 peer-reviewed analyses of extreme weather in 2018 including the research of 121 scientists from 13 countries. The severe Four Corners drought in the U.S., intense heat waves on the Iberian peninsula and in northeast Asia, exceptional precipitation in the mid-Atlantic states, and record-low sea ice in the Bering Sea were all examples of extreme weather events “made more likely by human-caused climate change.” As Jeff Rosenfeld, the editor-in-chief of the AMS series, noted, “We’ve now published more than 100 of these attribution studies in this AMS series and can see how powerful this science is getting. Attribution studies increasingly yield useful, nuanced conclusions that embrace real-world complexity,” Rosenfeld wrote. “They collectively make an ever starker statement about the human influence on extreme weather.”

Another example of a serious conceptual confusion is his chapter dismissing the threat of species extinctions. The chapter is full of misunderstandings of extinction rates, ecosystem and biological functions, confusions about timescales, and misuses of data. For example, Shellenberger confuses the concept of species “richness” with “biodiversity” and makes the astounding claim that

Around the world, the biodiversity of islands has actually doubled on average, thanks to the migration of ‘invasive species.’ The introduction of new plant species has outnumbered plant extinctions one hundred fold. (AN, p. 66)

By this odd logic, if an island had 10 species of native birds found only there and they went extinct, but 20 other invasive bird species established themselves, the island’s “biodiversity” would double. This error results from a misunderstanding of the study he cites, which properly notes that simply assessing species numbers (richness not biodiversity) on islands ignores the critical issues of biodiversity raised by invasive species, including the disruption of endemic species interactions, weakening of ecosystem stability, alteration of ecosystem functions, and increasing homogenization of flora and fauna.

Another set of classic logical fallacies is the misuse, misrepresentation, and selective use of evidence. Shellenberger sees himself as the white knight bringing science and facts to emotional arguments. “Every fact, claim, and argument in this book is based on the best-available science … Apocalypse Never defends mainstream science from those who deny it on the political Right and Left.” (AN, p. xiii) But often, his arguments are based on inappropriate use of evidence, outdated or cherry-picked science, misunderstandings or misrepresentation, or just outright errors.

One of the most common flaws is his confusing use of the terms “can,” “could,” “will,” “will likely,” and so on. These grammatical choices usually reflect classic Cornucopian optimism and the advantage of telling the audience a positive story, rather than one based on the actual evidence. For example, he claims:

When it comes to food production, the Food and Agriculture Organization of the United Nations (FAO) concludes that crop yields will increase significantly, under a wide range of climate scenarios. (AN, p. 6, emphasis added)

What great news, if only we knew for sure it were true and under all plausible climate scenarios. But in fact, this is a misrepresentation of the 2018 FAO report cited, which looks at possible futures and actually says:

Climate change already has negative effects on crop yields, livestock production and fisheries, particularly in low- and middle- income countries. Such impacts are likely to become even stronger later in this century. (emphasis added)

Unaddressed climate change, which is associated, inter alia, with unsustainable agricultural practices, is likely to lead to more land and water use, disproportionately affecting poor people and exacerbating inequalities within and between countries. This carries negative implications for both food availability and food access.

There are many other examples where his optimism (things “will” happen) overrides the scientific evidence and uncertainties about the future.

Misrepresenting what scientists actually say or said

Shellenberger’s discussion of nuclear energy and risk also misrepresents what scientists say. He states “mixing up reactors and bombs was, as we say, the go-to strategy for Malthusian environmentalists” (AN, p. 242), but to support this claim he offers the work of Drs. Paul and Anne Ehrlich and John Holdren in their 1977 book Ecoscience. Shellenberger quotes their factual statement that “A large reactor’s inventory of long-lived radioactivity is more than one thousand times that of the bomb dropped on Hiroshima.” (Ecoscience, p. 445) But he then falsely says they are implying reactors can explode like bombs: “The implication was wrong. Nuclear reactors cannot detonate like bombs.” (AN, p. 242) Shellenberger was eager to set up the strawman that “Malthusian environmentalists” don’t know the difference between nuclear reactors and nuclear bombs, but in the paragraph right before the statement he quoted, Ehrlich, Ehrlich, and Holdren (the latter trained in part as a nuclear physicist, by the way) literally write: “It is physically impossible for an LWR [light-water reactor] or any thermal-neutron reactor to blow up like a nuclear bomb.” (Ecoscience, p. 444)

This is just one of a series of misrepresentations of the works of the Ehrlichs and Holdren. Just a few paragraphs later, for instance, he says “Holdren and the Ehrlichs had to claim fossil fuels were scarce to oppose the extension of fertilizers and industrial agriculture to poor nations and to raise the alarm over famine.” (AN, p. 242) This is the exact opposite of what they have long argued. To quote Dr. Holdren: “What environmentalists mainly say on this topic is not that we are running out of energy, but that we are running out of environment – that is, running out of the capacity of air, water, soil, and biota to absorb” the environmental, social, and health impacts of burning fossil fuels. (emphasis added)

Another example of the confusions running through Shellenberger’s narratives is the section “Greed Saved the Whales, Not Greenpeace.” His argument is that cheap oil, epitomized by the discovery of oil in Pennsylvania, saved the whales: “The discovery of the Drake Well led to widespread production of petroleum-based kerosene… thus saving the whales.” (AN, p. 111) Just a page later, however, he acknowledges “But then, whaling came back, and in a big way. Between 1904 and 1978, whalers killed one million whales, nearly three times more than had been harvested before.” He then claims that cheap vegetable oils (ironically in the form of palm oil from deforestation in the Congo) saved the whales, but then again has to acknowledge that massive whale kills continued.

What finally led to today’s almost near moratorium on whale hunts? Not just changes in market forces, not changes in energy sources, not “greed” and the growth in wealth and prosperity as he argues, but the change in public opinion pushed by environmental groups and the public. And oddly, his last sentence in this chapter acknowledges this: “When it comes to protecting the environment by moving to superior alternatives, public attitudes and political action matter” (AN, p. 125) – exactly the point of environmental advocacy groups like Greenpeace that worked to change public opinion.

Who were the Neanderthals? | DW Documentary


DW Documentary

Published on Jan 23, 2021

Long before Homo sapiens populated the earth, the Neanderthals lived in Eurasia. Now, paleoanthropologists in England and France are using new archeological methods to shed light on some previously unexplained Neanderthal mysteries.

In an age clouded by the mists of time, the first early humans colonized the Eurasian continent. They settled on land that had only recently been covered by glaciers. This species, called Neanderthals, died out about 30,000 years ago — but at one time, they formed the largest group in an area that stretched from northern France to the Belgian coast and from the Channel Islands to southern England.

During the last Ice Age, the North Sea was frozen over — and the English Channel was a small river that could easily be crossed on foot. The Neanderthals lived in close harmony with their perpetually changing environment. They had everything they needed to survive: the meat of prey animals, edible wild plants, water and wood for cooking and heating. How did these early humans develop over almost 300,000 years? What were their lives like before they became extinct?

Our documentary is based on the latest research. We investigate various populations of Neanderthals, and visit archaeological sites in northern France, southern England, and on the island of Jersey.

Renowned researchers such as the British paleoanthropologist Chris Stringer and his French colleague Ludovic Slimak describe how the Neanderthals lived, and discuss their cognitive abilities. Was this species capable of structured thinking? Did they have cultures, languages, and societies? How intelligent were they, and what sort of adaptive strategies kept them alive for 300,000 years? How similar were they to modern-day humans?
