Forbes’ Rich List Of Nonsense

While it is no longer surprising, it remains disheartening to see a blistering attack on climate science in the business press where thoughtful reviews of climate policy ought to be appearing. Of course, the underlying strategy is to pretend that no evidence that the climate is changing exists, so any effort to address climate change is a waste of resources.
A recent piece by Larry Bell in Forbes, entitled “Hot Sensations Vs. Cold Facts”, is a classic example.
Bell uses the key technique that denialists use in debates, dubbed by Eugenie Scott the “Gish gallop”, named after a master of the style, anti-evolutionist Duane Gish. The Gish gallop raises a barrage of obscure and marginal facts and fabrications that appear at first glance to cast doubt on the entire edifice under attack, but which on closer examination do no such thing. In real-time debates the number of particularities raised is sure to catch the opponent off guard; this is why challenges to such debates are often raised by enemies of science. Little or no knowledge of a holistic view of any given science is needed to construct such scattershot attacks.
The approach also works somewhat in print, if the references are sufficiently obscure and numerous. Ideally, someone will take the time to answer such an attack, but there is a fundamental asymmetry of forces at work. It is, in fact, easier to form an allegation than to track down a reasonable explanation of what it means and how it really fits in to the balance of evidence. Also, the skills required to reflect the science are deeper than the ones required to attack it; hence the defenders are outnumbered and outgunned. Still, sometimes an article is prominent enough that it merits a detailed response.
The slightly out of the ordinary thing about Bell’s piece is that he casts his attack not as an attack on science (his usual method) but on the media:
As 2010 draws to a close, do you remember hearing any good news from the mainstream media about climate? Like maybe a headline proclaiming ‘Record Low 2009 and 2010 Cyclonic Activity Reported: Global Warming Theorists Perplexed’? Or ‘NASA Studies Report Oceans Entering New Cooling Phase: Alarmists Fear Climate Science Budgets in Peril’?” he begins.
But the remainder of the article is true to the form. Bell gallops through all the purported “good news” that the media ignored. The implication is that the media is complicit in overstating the climate change story.
But these aren’t the sorts of observations that most people generally receive from the media. Instead, they present sensational statements and dramatic images that leave lasting impressions of calving glaciers, drowning polar bears and all manner of other man-caused climate calamities.
Many intentionally target impressionable young minds and sensitive big hearts with messages of fear and guilt. Take, for example, a children’s book called The North Pole Was Here, authored by New York Times reporter Andrew Revkin. It warns kids that some day it may be “easier to sail than stand on the North Pole in summer.” Imagine such images through their visualization: How warm it must be to melt that pole way up north. Poor Santa! And Rudolph! Of course it’s mostly their parents’ fault because of the nasty CO2 they produce driving them to school in SUVs.
Lots of grown-ups are sensitive people with big hearts too. Don’t we all deserve more from the seemingly infinite media echo chamber of alarmism than those windy speculations, snow jobs and projections established on theoretical thin ice?
Whether the enemy is the “mercenary” scientific community, the “power hungry” liberal politicians or the “sensationalist” press matters little. What matters is to suggest the public has been manipulated, before starting the manipulation in earnest. The strategic point is to divert attention from what most scientifically informed people consider the key facts: the climate is changing as a result of human intervention. The longer we delay taking policy action, the more damage we will take and the more an effective policy will cost. It is conceivable and increasingly foreseeable that we will delay long enough that useful policy becomes infeasible and both human civilization and the biosphere will be permanently damaged.
The near-silence of the media on these matters is considered by many to be a key part of the problem. Yet, in this context, Bell suggests we are ignoring “the good news”.
Does he have a point? Is there really much of substance that qualifies as good news justifying his conclusion? The value of his piece depends crucially on how newsworthy his good news was, and how these items fit into the big picture.
We counted eleven assertions of fact in his gallop. Let’s look at each of them and place them in context. Bell especially emphasizes his first two points, so we examine them in detail (quotes from the article are bolded).
Record Low 2009 and 2010 Cyclonic Activity Reported
Bell’s first claim is not a confidence builder.
It’s possible that Bell is referencing a specific metric of hurricane activity (Accumulated Cyclone Energy), but that does not give a full story, nor does it show ‘record lows’. According to NOAA the 2010 Atlantic hurricane season, which ended Dec 31, was one of the busiest on record. In the Atlantic Basin a total of 19 named storms formed – tied with 1887 and 1995 for third highest on record. Of those, 12 became hurricanes – tied with 1969 for second highest on record. Five of those reached major hurricane status of Category 3 or higher. 2010 was just behind 2004 and 2005 for earliest occurrence of a third category 4 hurricane.
It is true that none of the 12 hurricanes made landfall in the US (though tropical storm Hermine made landfall in US and hurricane Karl made land fall in Mexico but caused major flooding in Texas. But the climate system cares nothing for national borders. This may be just a lucky break . Looking in detail it is attributable to some other features of the prevailing winds last year.
What is certainly untrue is that there was “record low” cyclonic activity in the Atlantic!
Did the press ignore this story? Even on this Bell’s leading point is dubious. But in the context of climate change, sea surface temperatures continue to increase and strong tropical cyclones continue their upward trend. So Bell leads off with a real clunker.
NASA Studies Report Oceans Entering New Cooling Phase
Bell’s second point, also from the lead paragraph:
According to two separate NASA studies, one conducted by the Jet Propulsion Laboratory, and the other by the Langley Research Center, the oceans now appear to be heading into another natural periodic cooling phase within a typical 55- to 70-year dipolar warm/cool pattern.
We traced this claim to an internet article by Justin Berk that says:
Two separate studies through NASA confirm that since 2003, the world’s oceans have been losing heat. …
Josh Willis, an oceanographer at NASA’s Jet Propulsion Lab, published his first report about the warming oceans. The article Correcting Ocean Cooling published on NASA’s Earth Observatory page this week discussed his and other results. Willis used data from 1993-2003 that showed the warm-up and followed the Global Warming Theory. In 2006, he co-piloted a follow-up study led by John Lyman at Pacific Marine Environmental Laboratory in Seattle that updated the time series for 2003-2005. Surprisingly, the ocean seemed to have cooled. He was surprised, and called it a ‘speed bump’ on the way to global warming.
But the excellent article “Correcting Ocean Cooling” which Berk references (and to which Bell is implicitly referring) for this actually explains how Willis went back and found that his earlier report of cooling was erroneous!
So the new Argo data were too cold, and the older XBT data were too warm, and together, they made it seem like the ocean had cooled,” says Willis. The February evening he discovered the mistake, he says, is “burned into my memory.” He was supposed to fly to Colorado that weekend to give a talk on “ocean cooling” to prominent climate researchers. Instead, he’d be talking about how it was all a mistake.”
Berk is so happy to find the word “cooling” in an article that despite the title “Correcting Ocean Cooling” he doesn’t bother to read or understand the whole point of the article. It’s really a very compelling example of how superficial this kind of journalism is; Berk gets something backwards, Bell picks it up, and Forbes, no less, uses it to lead off an article (albeit an op-ed column).
What’s more, the NASA article itself is from 2008, so even if the press had reported it as news as Larry Bell suggests, it would not have been in 2010. But in fact, the news was that the previous evidence of cooling was erroneous. Bell’s second point is simply wrong as well.
Now that we have some sense of the quality of Bell’s research, we’ll go a little more quickly through most of the other points, saving for last a case where he might have a stronger point.
A special press conference called by IPCC spokesman Kevin Trenberth announced “Experts warn global warming likely to continue spurring more outbreaks of intense activity.” Christopher Landsea, a top U.S. expert on the subject, repeatedly notified the IPCC that no research had been conducted to support that claim–not in the Atlantic basin, or in any other basin.
This famous controversy occurred in 2004 and is not 2010 news. Nor was it ignored by the press. We doubt that Landsea went so far as to claim that “no research had been conducted to support that claim” but if he did he is certainly incorrect. This topic goes back at least to 1987 with a paper in Nature by Kerry Emanuel. Kevin Trenberth offers some salient points about the controversy from his point of view:
1. I was not an IPCC spokesperson and I was not advertised as such. Landsea claimed otherwise.
2. I did not call the press conference, it was called by Harvard university (Paul Epstein and Jim McCarthy), I participated.
3. There was a ton of research including my own on changes in the hydrological cycle that were pertinent but not specifically Tropical Storm based, as well as Kerry’s work.
4. Landsea did not notify IPCC once, let alone repeatedly. He called a press conference and resigned from IPCC but he was not even part of IPCC. He had been asked by me to write something as a contributing author. It was a horrible distortion of many facts.
A globally viewed December 2005 BBC feature alarmingly reported that two massive glaciers in eastern Greenland, Kangderlugssuaq and Helheim, were melting, with water “racing to the sea.” … Only 18 months later, and despite slightly warmer temperatures, the melting rate of both glaciers Kangderlugssuaq and Helheim not only slowed down and stopped, but actually reversed.
This again is not 2010 news since it happened in 2007. It is a fact that after a massive retreat from 1991 to 2005 Kangderlugssuaq regained a tiny fraction, less than a tenth, of that retreat by 2007. This may be of interest to glacier dynamicists, but its climatological importance is nil. Glaciers worldwide are in massive retreat. Indeed, Kangerdlugssuaq Glacier lost another 5.2 square km in 2009.
[The] ice cap has been accumulating snow growth at a rate of about 2.1 inches per year
The top of the ice caps are growing slightly as expected, since warmer air contains more moisture which will fall in those places as snow. The issue that the public ought to pay attention to is the much larger and accelerating melt at the edge of the ice sheet. This is not especially 2010 news, but in any case it is sleight of hand. The real action is the instability at the edges, which already dominates the accumulation in the interior and looks likely to overwhelm it.
The new sea level, which has been stable, has not changed in the last 35 years.

… if you want a grant for a research project in climatology, it is written into the document that there ‘must’ be a focus on global warming.
There are many grants supported by the grant agencies. Some are very broad and some very narrow. While it is possible that some grants specify “global warming”, it is relatively unusual. Currently open climate calls in the US through NSF can be seen at here. The claim simply isn’t true.
The Indian Ocean, for example, was higher between 1900 and 1970 than it has been since.
This is at least a current topic. It probably is based in Patterns of Indian Ocean sea-level change in a warming climate, Han et al. Nature Geoscience 2010. They conclude that “sea level has decreased substantially in the south tropical Indian Ocean whereas it has increased elsewhere. This pattern is driven by changing surface winds associated with a combined invigoration of the Indian Ocean Hadley and Walker cells, patterns of atmospheric overturning circulation in the north–south and east–west direction, respectively, which is partly attributable to rising levels of atmospheric greenhouse gases.”
So yes, there are apparently parts of the Indian Ocean where sea level has declined. This just leaves more water to pile up elsewhere. In fact, it shows how powerful the forces of climate change already are, in order to be able to outweigh the generally rising ocean volume in a limited area. It is hard to see how this rises to a general interest topic or how it qualifies as “good news” though.
The Northwest Passage has certainly opened up before.
This is untrue in recorded history. The traversals prior to 2007 were in very specialized boats and often took years. In 2007 and 2010, genuine shipping lanes opened up for the first time. It was possibly open in the mid-Holocene about 6,000 to 8,000 years ago and was certainly open millions of years ago. But since the opening of the passage itself received far too little attention (in our opinion), it is hard to see what Bell is complaining about.
in February 2009 it was discovered that scientists had previously been underestimating the re-growth of Arctic sea ice by an area larger than the state of California (twice as large as New Zealand)
“Previously” is grossly misleading. This was an instrumental glitch that lasted a few weeks. And February 2009 was not in 2010 either.
… previous estimates of Greenland and West Antarctica ice melt rate losses may have been exaggerated by double.
We’ve saved this for last because here Bell has a fraction of a point; as far as we can tell the only thing he raises that is 1) current and 2) arguably of general interest and 3) arguably good news. The use of the word “exaggerated” however is malicious and unjustified.
There are a number of ways of estimating the large scale mass balance of the ice sheets. Prominent among them uses information from the GRACE satellite, which measures the gravitational field of the earth. By its nature, the resulting measures are very large scale. They are complemented by precise local measures of ice altitude, for example, which are precise but cannot give broad coverage. To estimate ice cap melting the GRACE results also have to be combined with an estimate of the post-glacial rebound from the last ice age (which is still affecting the mass distribution of the Earth’s crust). Observing a planet is tricky business.
A recent publication by Wu et al makes the claim that:
“these [previous] results were not properly corrected for glacial isostatic adjustment, the phenomenon that the Earth’s crust rebounds as a result of the melting of the massive ice caps from the last major Ice Age around 20,000 years ago. These movements of the Earth’s crust have to be incorporated in the calculations, since these vertical movements change the Earth’s mass distribution and therefore also have an influence on the gravitational field.”
There is some contention here. If it proves true, it is an example of science at its best; a sequence of corrections converging on objective truth. The original estimates would have been corrected, pretty much by a factor of two as Bell says.
So this is current, substantially good news, and possibly salient for a general audience. On the other hand it is only good news about bad news; the ice retreat may have been overestimated, but we are still talking about hundreds of billions of tons more ice melting than accumulating every year, and this rate still shows signs of accelerating.
In this case, it is worth noting that all the evidence is that the ice sheets are losing mass and that the loss is accelerating. The Wu et al paper would be simply a recalibration of the net loss. This is good news, but not great news, and is certainly no evidence at all that climate change is negligible.
Please notice how we are trapped in a polemical double bind here.
What the naysayers will do is celebrate every correction that makes matters look less dangerous and criticize every correction that makes matters look more dangerous. In the former case, the older measure will have been “exaggerated”, and “corrected” by some noble and courageous hero. In the latter case, the newer measure is treated as the “exaggeration”. Thus, every single change in the estimate of any quantity is treated as evidence of the grand conspiracy.
What should be celebrated as advances of truth are instead recast either as the bad scary science defeated by the good non-scary science or the other way around. This is especially evident in the clumsy way the Willis tale is told, wherein the casting is confused because one person takes both roles.
So what remains of the criticism Bell raises? Very little indeed! The only unreported good news is that ice cap melting might have been overestimated, though it is still large and probably accelerating. The other ten of his eleven points are essentially nonsensical. I am not being partisan or oppositional here. I examined every point with an open mind and came up with ten points that boil down to complete nonsense and the last one a bit heavy on the spin.
Ultimately, though, the criticism of the press is ludicrous. The naysayers ought to be thrilled at the lack of interest in climate change shown in the press, at least in North America. The longer we delay, the bigger the topic gets, and the more ridiculous the refusal of the press and policy sector to grapple with it becomes.
Yet widely respected publications like Forbes seem eager to promulgate great clouds of rhetorical ink to make the problem seem ever more trivial and distant. If there is good news of general interest, of course it should be reported. But Bell seems to want, instead, to invent it.
