How Climate Deniers Take Advantage of Science to Lie About Science

It's a recurring practice. A new climate study comes out and suddenly the internet is saturated with "reinterpretations" by climate deniers of what the study says. This is how climate denier lobbyists misrepresent, aka lie, about the science. The most recent is how they have lied about a new study released by NASA regarding mass gains in Antarctica.

Keep in mind that science is incremental. One study generally isn't meaningful by itself. Science is the compendium of all related studies. For example, one study may suggest that (under the conditions of the study) Antarctica is gaining more ice than it is losing while other studies show that West Antarctica may have gone into a state of irreversible retreat. That doesn't make any one study right or wrong, merely additional data points in the total understanding of the science. It's how science works.

A summary of this particular study being misrepresented can be found in NASA's press release. You can download the full study as a PDF file from this journal site. I highly recommend anyone wanting to understand the study read the actual paper because press releases often do a lousy job of communicating the science. Yes, I know, communicating the science is what press releases are designed to do, but my experience tells me that they  introduce confusion as often as they inform, in part because they report single studies and not the total science. I'll tackle that topic in another post.

The inadequacy of press releases for studies and the very nature of how science works results in opportunities for climate denier lobbyists to exploit uncertainties. And that is exactly what they do.

In this case we have information that may (or may not) contradict other information and the lobbyists pounced on it. As is their standard tactic, deniers take one point from the paper, fabricate an entire story line that fits their narrative, and put the false story line out on their paid lobbyist blog and media outlets. These lobbyists know that their false story will be plagiarized and repeated on every conspiracy and political blog by ideologues until the blogosphere is saturated with the false interpretation. That's how climate denial lobbyists work.

Greg Laden, a scientist who writes on Science Blogs, explains how the NASA study has been "misunderstood." [I think Greg is giving the blogosphere too much benefit of the doubt by using the term "misunderstood;" as the recent revelations about Exxon's knowledge decades ago that fossil fuels were causing climate change show, climate denial lobbyists know they are misrepresenting (i.e., lying about) the science. It's intentional.] That said, Greg notes that to begin with, the study may not be correct. While touted as "recent data" the data set used actually ended in 2008 so would miss the rapid ice loss of the last seven years. As Greg notes:

The last decade of research on Antarctica have shown, in many studies using a variety of techniques, that Antarctica is contributing to sea level rise. They have also shown that the rate of melting in Antarctic is probably increasing. Even more importantly, they have indicated that certain areas of Antarctic are current in a state of instability, suggesting that the rate of contribution of the southern continent’s ice mass to sea level rise may increase abruptly in the near future.

So the study, like all studies, needs to be placed into context with the state of the science. Deniers never do that; they cherry pick what they like and make believe all the rest of the science doesn't exist. This tactic is so prevalent in climate denial that the lead scientist of the study even predicted that climate deniers would misrepresent his work, which is exactly what they did, as reported in the above linked article:
"I know some of the climate deniers will jump on this," but "it should not take away from the concern about climate warming."

The first lesson here is that it isn't appropriate to take one study and assume it represents the total state of the science. Science is the sum total of all the relevant studies. The second lesson is that the climate denial lobbyists knowingly and willfully misrepresent single studies and then draw global "state of the science" conclusions that are inconsistent with the sum total of all the science.

This idiocy has been the platform of the oligarchs and TEATwit politicians since the first IPCC study was released. It is, in fact, far older than any significant public discourse about Climate Change or Global Warming. The techniques of the deniers was honed in the tobacco wars of the '70s and '80s, In fact, one of the leading "scientists" (he actually does have a PhD in a scientific field) ha been a leader in this assault on climate science, using the same techniques he developed and perfected working for the Tobacco Institute.

First they will post a triumphant paean to the "proof" of their correctitude being borne out by climate scientists. Then they will begin ridiculing any discussion like this blog that can't refute them in two sentences or less. Next will come a lot of LOLing and LMAOing, and even some ROFLMAOing at any explanation that includes real science, along with a good bit of reminiscing about the climate "alarmists'" "god," Al Gore, and the always popular referencing of the short-lived (and mostly news magazine hyped and never widely accepted) perception in the '70s that the planet was headed into another ice age. Unfortunately for them, ridicule has never, to my knowledge, changed a single fact or data point.

As I told a neighbor (who has two graduate degrees in science - math and information technology)who told me he "had to disagree with me on global warming," they will agree with me sooner or later, and it's looking a lot like sooner.

The climate denial lobby does have its roots in the tobacco lobby denying smoking causes cancer. As you say, they even employ some of the same people and lobbying front groups (e.g., Fred Singer and Heartland Institute). The tactics are well known, and well rehearsed.

Currently there is a push by some to use the RICO laws (racketeering) to query Exxon's role in suppressing their own scientists' knowledge about climate change. This is how the tobacco firms and lobbyists were brought to admit their deceptions, so there is precedent for its use. On the other hand, Exxon has been playing both sides of the coin for a long time - supporting the denial of climate science while simultaneously working on alternatives that would put them ahead of competitors (and, of course, reaping huge profits from fossil fuels for as long as they can).

As your neighbor will eventually admit, the science is the science. Denying it doesn't make it go away. The public is coming to terms with the fact of man-made climate change, and deniers are simply looking foolish and dishonest by continuing to deny it.
