Extract from Steve Koonin's climate science book “Unsettled”. My personal view is: The Science is almost settled on the changing Sun and Sun-Earth relationship as the cause of almost all climate change; with the greenhouse gas effect being, essentially, fake science.
WHO BROKE “THE SCIENCE” AND WHY, Steve Koonin
Chapter 10, of “Unsettled”, by Steve Koonin, 2021.
If crucial parts of the science really are unsettled, as we’ve seen over the
past chapters, why is the narrative of The Science so different? Can it really
be that the multiplicity of stakeholders in climate matters—scientists,
scientific institutions, activists and NGOs, the media, politicians—are all
contributing to misinformation in the service of persuasion? And why has
The Science gained such prominence over science?
Observing this scene over the years, I’ve given a lot of thought to how
the communication of climate science works. I’m no expert on human
behavior, but I have seen this process up close, and my direct experiences,
along with some universal truths about humans, suggest not some secret
cabal, but rather a self-reinforcing alignment of perspectives and interests.
Let’s look at the most important players in turn.
THE MEDIA
When I moved to the UK in 2004, I naturally began reading the British
newspapers. I was struck by how much more international coverage there
was than in the US, no doubt because the smaller UK necessarily has more
foreign interactions, as well as ties to the rest of Europe and historical
relationships with Commonwealth countries once part of the British Empire.
And of course, soccer—that is, football—got many more column inches.
But what surprised me most wasn’t only a matter of content, but tone.
The British papers were often overtly partisan, not just in their editorials,
but also in their reporting. Although I had read widely among US national
newspapers, including the New York Times, the Wall Street Journal, and the
Washington Post, it was a revelation to see the stark differences in what was
covered, and how it was covered, among the UK’s Guardian, the (London)
Times, the Telegraph, and the Financial Times.
In the years since, US media outlets have developed more explicit
and more differentiated points of view themselves, and those have likewise
seeped from their editorial pieces into their reporting. Most notably,
as the age of the internet advanced, headlines became more provocative
to encourage clicks—even when the article itself didn’t support the
provocation. Today, the shift toward the alarming—and shareable—has
traveled well beyond the headlines. That’s especially true in climate and
energy matters.
Whatever its noble intentions, news is ultimately a business, one that
in this digital era increasingly depends upon eyeballs in the form of clicks
and shares. Reporting on the scientific reality that there’s been hardly any
long-term change in extreme weather doesn’t fit the ethos of If it bleeds it
leads. On the other hand, there is always an extreme weather story somewhere
in the world to support a sensational headline.
Changes in staffing also contribute to the media miscommunication
of the science. Many newsrooms are shrinking, and serious in-depth
reporting is becoming less common. Many people reporting on climate
don’t have a background in science. This is a particular problem because,
as we’ve seen, the assessment reports themselves can be misleading, especially
to non-experts. Science stories are almost always stories of nuance;
they require time and research. Unfortunately, the pace of the news cycle
has only become more frantic, and reporters and editors have less time
than ever. The diversity and ubiquity of modern media have increased the
demand for fresh “content” and the competition to be the first to post a
story. And as with scientists, a professional code that calls for lack of bias
doesn’t mean none creeps in.
As I interact with journalists, I realize that, for some, “climate change”
has become a cause and a mission—to save the world from destruction by
humans—so that packing alarm into whatever the story is becomes the
“right” thing to do, even an obligation. This has been compounded by the
rise of a new job category: “climate reporters.” Their mission is largely
predetermined; if they don’t have a narrative of doom to report, they won’t get
into the paper (whether digital or print) or on the air.
Here’s an example. A recent front-page story in the Washington Post
reported that the Biden administration’s climate policy would aim “to
rapidly shrink the nation’s carbon emissions,” explaining that “a warming
planet has made the issue increasingly hard to ignore, as the litany of
climate-related catastrophes has grown with each passing year.”1
Of course, as you have already read, the data does not at all support
that “climate-related catastrophes” are growing “with each passing year.”
There’s much factual reporting in the full-page story that follows
about plans for the new administration. But without those initial alarm
bells, would the story have made it to the front page?
In short, the general lack of knowledge of what the science actually
says, the drama of extreme weather events and their heart-rending impact
on people, and pressures within the industry all work against balanced
coverage in the popular media.
POLITICIANS
Politicians win elections by arousing passion and commitment from
voters—by motivating and persuading. This is not new. H. L. Mencken’s
1918 book In Defense of Women noted:
The whole aim of practical politics is to keep the populace alarmed
(and hence clamorous to be led to safety) by menacing it with an endless
series of hobgoblins, most of them imaginary.2
The threat of climate catastrophe—whether storms, droughts, rising
seas, failed crops, or economic collapse—resonates with everyone. And
this threat can be portrayed as both urgent (by invoking a recent deadly
weather event, for instance) and yet distant enough so that a politician’s
dire predictions will be tested only decades after they’ve left office. Unfortunately, while climate science and associated energy issues are complicated, complexity and nuance don’t lend themselves at all well to political
messaging. So the science is jettisoned in favor of The Science, and “simplified” for use in the political arena, which allows the required actions to
be portrayed simply as well—just eliminate fossil fuels to save the planet.
Of course, this isn’t a climate-specific problem, and the electorate—
which abhors a gray area—bears part of the blame. It’s hard to rally the
base with uncertainty. There would surely be less support for, say, promoting
renewable energy sources if they were more realistically portrayed as
a possible way to mitigate a possible future problem instead of an essential
solution to an imminent crisis. And uncertainty can be a political weapon.
Politicians on the right who deny even the basics that science has settled—
that human influences have played a role in warming the globe—are not
above exploiting climate science uncertainties, offering them as “proof”
that the climate isn’t changing after all.
Politicians on the left find it inconvenient to discuss scientific uncertainties
or the magnitude of the challenge in reducing human influences.
Instead, they declare the science settled and label anyone who questions that
conclusion “a denier,” lumping conscientious scientists advocating for less
persuasion and more research in with those openly hostile to science itself.
Some politicians have gone far beyond name-calling, brazenly attempting
to undermine the scientific process. Two billionaire politicians, Michael
Bloomberg and Tom Steyer, whose goal was “making the climate threat
feel real, immediate, and potentially devastating to the business world,”
conspired with some scientists and others to produce a series of reports
mischaracterizing the extreme emissions scenario RCP8.5 as “business
as usual” (that is, a world without further efforts to rein in emissions).3, 4
The reports were accompanied by a sophisticated campaign to infuse that
notion into scientific conferences and journals.5 Those who seek to corrupt
the scientific process in that way are playing the same game as the anti-
science crowd they loudly decry. Fortunately, the deception is now being
called out in leading scientific journals.6,7
Finally, it is standard practice to suggest that many of the politicians
on the right who promulgate the idea of a “climate change hoax” are influenced
by ties to industries negatively affected by restrictive environmental
regulation. Alas, as the alternative energy industry grows, there is financial
incentive for politicians to hype climate catastrophe as well. Science
should not be partisan, but climate science’s intersection with energy
policy and politics all but guaranteed that it would become so.
SCIENTIFIC INSTITUTIONS
Trust in scientific institutions underpins our ability—and the ability of
the media and politicians as well—to trust what is presented to us as The
Science. Yet when it comes to climate, those institutions frequently seem
more concerned with making the science fit a narrative than with ensuring
the narrative fits the science. We’ve already seen that the institutions that
prepare the official assessment reports have a communication problem,
often summarizing or describing the data in ways that are actively misleading.
In the next chapter, we’ll delve a bit further into how this happens;
I won’t belabor the point here.
Other scientific institutions, or their leaders, have also been overwilling
to persuade rather than inform. The National Academies of Sciences,
Engineering, and Medicine (NASEM) is a private, nonprofit institution
chartered by the US Congress in 1863 to advise the nation. To quote from
their website:
The National Academies of Sciences, Engineering, and Medicine are
the nation’s pre-eminent source of high-quality, objective advice on
science, engineering, and health matters.8
The Academies provide that advice largely through written reports
sponsored by federal agencies. Some two hundred reports are published
each year, dealing with a great range of topics in science, engineering,
medicine, and the societal issues associated with them.9
Academies reports undergo an extensive authoring and review process. I know that process well, having led two Academies studies and
reviewed the reports of several others, along with for six years overseeing all the Academies’ report activities in Engineering and the Physical
Sciences (including several in Energy, but none in Climate Science). This
process does indeed result in reports that are almost always objective and
of the highest quality. Unfortunately, as we’ve seen, their reviews of the
National Climate Assessments (they don’t write the assessments themselves) in 2014 and 2017/18 didn’t quite meet that standard.
On June 28, 2019, the presidents of the National Academies of Science,
Engineering, and Medicine issued a statement affirming “the Scientific
Evidence of Climate Change.” The sole paragraph dealing with the science
itself read:
Scientists have known for some time, from multiple lines of evidence,
that humans are changing Earth’s climate, primarily through greenhouse gas emissions. The evidence on the impacts of climate change
is also clear and growing. The atmosphere and the Earth’s oceans are
warming, the magnitude and frequency of certain extreme events are
increasing, and sea level is rising along our coasts.10
Even given the need for brevity, this is a misleadingly incomplete
and imprecise accounting of the state of climate science. It conflates
human-caused warming with the changing climate in general, erroneously
invokes “certain extreme events” while omitting the fact that most types
(including those that pop most readily to mind when one reads the phrase
“extreme events,” like hurricanes) show no significant trend at all. And it
states that “sea level is rising” in a way that not only suggests that this, too,
is solely attributable to human-caused warming, but elides the fact that the
rise is nothing new.
I’m quite sure that this personal statement issued by the presidents in
a news release was not reviewed by the usual Academies procedures; if it
had been, its deficiencies would have been corrected. The statement therefore carries the weight of the Academies’ name without being subject to
its customary rigor. Ironically, the statement goes on to say the Academies
“need to more clearly communicate what we know.” Which in this case
they didn’t.
When communication of climate science is corrupted like this, it undermines the confidence people have in what the scientific establishment says
about other crucial societal issues (COVID-19 being the outstanding recent
example). As Philip Handler, a prior president of the National Academy of
Sciences, wrote in the 1980 editorial I mentioned in the Introduction:
It is time to return to the ethics and norms of science so that the
political process may go on with greater confidence. The public may
wonder why we do not already know that which appears vital to
decision—but science will retain its place in public esteem only if we
steadfastly admit the magnitude of our uncertainties and then assert
the need for further research. And we shall lose that place if we dissemble or if we argue as if all necessary information and understanding were in hand. Scientists best serve public policy by living within
the ethics of science, not those of politics.11
SCIENTISTS
This book’s introduction described Stephen Schneider’s false choice
between being effective and being honest. But there are other factors that
encourage climate researchers’ monolithic portrayal of the science as
settled, however vigorous their internal debates might be. Feynman closes
his Cargo Cult speech by wishing the Caltech graduates
the good luck to be somewhere where you are free to maintain the
kind of integrity I have described, and where you do not feel forced
by a need to maintain your position in the organization, or financial
support, or so on, to lose your integrity.
I know from experience that such institutional pressures are real;
whether you’re working for the government, a corporation, or an NGO,
there is a message to be adhered to. For academics, there is pressure to generate press and to secure funding through grants. There’s also the matter of
promotion and tenure. And there is peer pressure: more than a few climate
contrarians have suffered public opprobrium and diminished career prospects for publicizing data that doesn’t support the “broken climate” meme.
Carl Wunsch, a prominent oceanographer from MIT who has long
urged scientists to be realistic in their portrayal of the science,12 has written about the pressures on climate scientists to produce splashy results:
The central problem of climate science is to ask what you do and say
when your data are, by almost any standard, inadequate? If I spend
three years analyzing my data, and the only defensible inference is
that “the data are inadequate to answer the question,” how do you
publish? How do you get your grant renewed? A common answer is
to distort the calculation of the uncertainty, or ignore it all together,
and proclaim an exciting story that the New York Times will pick up.
A lot of this is somewhat like what goes on in the medical business: Small, poorly controlled studies are used to proclaim the efficacy
of some new drug or treatment. How many such stories have been
withdrawn years later when enough adequate data became available?13
Scientists not involved with climate research are also to be faulted.
While they’re in a unique position to evaluate climate science’s claims,
they’re prone to a phenomenon I call “climate simple.” The phrase “blood
simple,” first used by Dashiell Hammett in his 1929 novel Red Harvest,
describes the deranged mindset of people after a prolonged immersion
in violent situations; “climate simple” is an analogous ailment, in which
otherwise rigorous and analytical scientists abandon their critical faculties when discussing climate and energy issues. For example, the diagnosis
was climate simple when one of my senior scientific colleagues asked me
to stop “the distraction” of pointing out inconvenient sections of an IPCC
report. This was an eyes-shut-fingers-in-the-ears position I’ve never heard
in any other scientific discussion.
What causes climate simple? Perhaps it is a lack of knowledge of the
subject, or fear of speaking out, particularly against scientific peers. Or
perhaps it is simple conviction born more of faith in the proclaimed consensus than of the evidence presented.
Leo Tolstoy’s 1894 philosophical treatise The Kingdom of God Is Within
You contains the following thought:
The most difficult subjects can be explained to the most slow-witted
man if he has not formed any idea of them already; but the simplest
thing cannot be made clear to the most intelligent man if he is firmly
persuaded that he knows already, without a shadow of doubt, what is
laid before him.14
Whatever its cause, climate simple is a problem. Major changes in society are being advocated and trillions will be spent, all based on the findings of climate science. That science should be open to intense scrutiny
and questioning, and scientists should approach it with their usual critical
objectivity. And they shouldn’t have to be afraid when they do.
ACTIVISTS AND NONGOVERNMENTAL ORGANIZATIONS (NGOS)
My inbox fills with fundraising appeals from such organizations as 350.org, the Union of Concerned Scientists, and the Natural Resources
Defense Council. If you believe there is a “climate emergency,” have built
an organization on that premise, and rely upon your donors’ continuing
commitment to the cause, projecting urgency is crucial. Hence statements
like “The climate crisis is immense—we must be daring and courageous
in response” (from the 350.org website15) or “Climate change is one of the
most devastating problems that humanity has ever faced—and the clock
is running out” (from the UCS website16). It’s hardly in your best interest
to tell your donors that the climate shows no sign of being broken or that
projections of future disasters rely on models of dubious validity.
The media tend to accord NGOs an authoritative stance. But these
are also interest groups, with their own climate and energy agendas. And
they are powerful political actors, who mobilize supporters, raise money,
run campaigns, and wield political power. For many, the “climate crisis” is
their entire raison d’etre. They also have to worry about being outflanked
by more militant groups.
I have no problem with activism, and the efforts of NGOs have made
the world better in countless ways. But distorting science to further a
cause is inexcusable, particularly with the complicity of those scientists
who serve on their advisory boards.
THE PUBLIC
Fear of extreme weather events is understandable, and concerns about
changes in climate are as old as humanity. Short-term weather events
(storms, floods, droughts) have stressed and challenged societies, while
changes extending over decades induced mass migrations or even
destroyed entire civilizations. For example, repeated crop failures devastated communities in the southwest United States during the twenty-five-year-long Great Drought about 750 years ago.17
The notion that our behavior might be causing such calamities is also
as old as humanity—as is the hope that we might avoid the worst of climate
disasters by changing our behavior. Leviticus 26:3–4 promises regular rain
(very important in the Middle East) and its ensuing benefits in return for
doing the right thing:
If ye walk in my statutes, and keep my commandments, and do them;
Then I will give you rain in due season, and the land shall yield her
increase, and the trees of the field shall yield their fruit.
We like to think public attitudes toward climate today are more discerning, but they still mostly involve unquestioning acceptance of wisdom
handed down from on high. As around the world, most citizens in America
are not scientists, and the educational system does not deliver much in
the way of scientific literacy to the wider public. Most people do not have
the ability to examine the science themselves, and they have neither time
nor the inclination to do so. Many increasingly get their information from
social media, where it is far too easy to promote misinformation or disinformation. And in my experience, people tend to believe—and trust—their
chosen media in areas outside their expertise.
Michael Crichton, the bestselling author of The Andromeda Strain
and Jurassic Park, lived near Caltech and was a prominent member of
Pasadena’s extended intellectual community until his death in 2008.
Crichton, who was a physician before he became a writer, was an outspoken advocate for scientific integrity, and he looked askance at the public
presentation of climate science (his 2004 novel State of Fear deals with
that subject). Crichton’s conversations with Caltech professor Murray
Gell-Mann (the Nobel prize–winning physicist who was one of the first
researchers to hypothesize quarks) led him to describe the “Gell-Mann
Amnesia” effect:
You open the newspaper to an article on some subject you know well.
In Murray’s case, physics. In mine, show business …
In any case, you read with exasperation or amusement the multiple errors in a story, and then turn the page to national or international affairs, and read as if the rest of the newspaper was somehow
more accurate about Palestine than the baloney you just read. You
turn the page, and forget what you know.18
It certainly doesn’t help that, at this point, even attempting a discussion of The Science is to enter a political minefield. When I tell people
some of the things the assessment reports really say about climate, many
immediately ask whether I was a Trump supporter. My reply is that I was
not, and that, as a scientist, I have always supported truth.
As a scientist, I’m disappointed that so many individuals and organizations in the scientific community are demonstrably misrepresenting the
science in an effort to persuade rather than inform. But you also should be
concerned as a citizen. In a democracy, voters will ultimately decide how
society responds to a changing climate. Major decisions made without full
knowledge of what the science says (and doesn’t say) or, even worse, on the
basis of misinformation, are much less likely to lead to positive outcomes.
COVID-19 offered a sobering illustration of this, and it’s as true for climate
and energy as it is for pandemics.
