GUARDIAN: Breitbart Doesn’t Write What We Believe… So They’re Biased

From The Guardian

Isoprene: it’s a gas that helps aerosols form in the atmosphere. It’s relevant to climate change because aerosols help clouds form, which can have cooling (by reflecting sunlight) or warming (by trapping heat) effects, depending on the type of cloud. Aerosols also cause cooling by directly scattering sunlight.

Past field measurements indicated that the oceans were releasing less isoprene than climate model simulations suggested they should. A new study found that previously unidentified reactions in the sea surface microlayer might represent a significant source of isoprene that could reconcile the discrepancy between measurements and models. In fact, climate models may even be underestimating the amount of isoprene released from the oceans.

Not relevant to global warming

What are the implications of this study for recent global temperature changes? As co-author Dr. Christian George told Carbon Brief,

Our study is a new brick that should help understanding our complex world, by providing new knowledge on air-sea exchanges, but it definitively does not question climate change, it just helps us understand its impact.

There is no question that the global climate will become warmer. The question is just how much, how fast and how the effects will change our lives.

Professor Piers Forster explained why suggestions that this study have significant climate change implications are wrong for several reasons. The primary reason is that changes in global temperature would only be caused by changes in natural isoprene emissions. As Forster noted,

The natural aerosol cooling could be 100 times bigger than our current estimate, but it would make no difference to climate change as it would stay more-or-less constant with time.

Marine isoprene releases could only cause global warming or cooling if the level of the emissions were to change. However, this paper merely suggests that the overall level of isoprene emissions is higher than previously thought, not that the levels are changing. And in fact the study indicates that climate model simulations might be more accurate on ocean isoprene emissions than previously believed.

Conservative media outlets choose propaganda over journalism

However, several conservative media outlets falsely claimed that the study had uncovered a “global cooling process.” Writing for Breitbart, James Delingpole claimed that the paper “may pose a serious threat to man-made global warming theory.” The Register and Express both claimed that temperatures have been stable for 15 years (they’ve actually risen by about 0.2°C during that time), and that this paper could explain that fictional temperature stability.

The problem lies in the fact that unlike Carbon Brief, whose reporters discussed the study and its implications with two climate scientists including one of the study authors, these conservative media outlets tried to interpret its meaning on their own. This led to mischaracterizations of the paper that Professor Forster described as “quite crazy.”

All of these conservative media pieces misrepresenting the paper shared another characteristic. Each revealed its bias by wishfully suggesting the international climate negotiations that will soon be held in Paris could be undermined by the study’s findings.

Rather than contact the study’s authors or any other climate scientists, the Express and Breitbart quoted Benny Peiser, a social anthropologist, climate fake expert, and director of the anti-climate policy Global Warming Policy Foundation (GWPF). The UK government’s Charity Commission ruled last year that the GWPF was blurring fact and comment on climate change, lacked neutrality, and promoted a contrarian position on the subject.

In essence, The Register, Express, and Breitbart seemed more interested in promoting a specific political cause – undermining efforts to implement climate policies – than in getting the facts right. And presenting misleading information to promote a political agenda is the very definition of propaganda.

Ironically, Delingpole accused Carbon Brief of being an “eco-propaganda website,” even though it was Carbon Brief that ensured factual accuracy by discussing the study and its implications with one of the study’s authors and a second climate scientist. Worse yet, Delingpole implied that Professor Forster is “stupid, dishonest, and semi-literate,” among other insults, for having the temerity to point out the factual inaccuracies in the Breitbart propaganda piece. This is the same James Delingpole who told Sir Paul Nurse in a climate conversation on BBC (a conversation in which Delingpole complained he was “intellectually raped”),
