The AP Stylebook editors today informed AP staff about a change to the entry on global warming. In addition, they described what goes into keeping the Stylebook up-to-date, including their outreach to experts.
AP science writer Seth Borenstein was among those who provided guidance during the discussion that resulted in today’s change, which adds two sentences to the global warming entry.
Here is the staff memo from Stylebook editors Sally Jacobsen, Dave Minthorn and Paula Froke:
We have reviewed our entry on global warming as part of our efforts to continually update the Stylebook to reflect language usage and accuracy.
We are adding a brief description of those who don’t accept climate science or dispute the world is warming from man-made forces:
Our guidance is to use climate change doubters or those who reject mainstream climate science and to avoid the use of skeptics or deniers.
Some background on the change: Scientists who consider themselves real skeptics – who debunk mysticism, ESP and other pseudoscience, such as those who are part of the Center for Skeptical Inquiry – complain that non-scientists who reject mainstream climate science have usurped the phrase skeptic. They say they aren’t skeptics because “proper skepticism promotes scientific inquiry, critical investigation and the use of reason in examining controversial and extraordinary claims.” That group prefers the phrase “climate change deniers” for those who reject accepted global warming data and theory. But those who reject climate science say the phrase denier has the pejorative ring of Holocaust denier so The Associated Press prefers climate change doubter or someone who rejects mainstream science.
To describe those who don’t accept climate science or dispute the world is warming from man-made forces, use climate change doubters or those who reject mainstream climate science. Avoid use of skeptics or deniers.

Statement from Anthony Watts:
I would like to say we’re at a point where global warming is impossible to deny. Let’s just say that global warming deniers are now on a par with Holocaust deniers, though one denies the past and the other denies the present and future. – Ellen Goodman, Boston Globe, February 9, 2007 “No change in political climate” (non-paywalled here)

I don’t see this as a step forward. it’s a step to one side.
So, we’re all Doubting Thomas’s now, rather than true sceptics? ‘Denier’ as used by CAGW advocates implicitly rules out scientifically valid scepticism. This fact is often explicitly levied at those who question consensus climate science in the form of insulting references to their supposed ‘faux scepticism’ or ‘pseudo-scepticism’. So in effect, all AP are doing is removing the use of one negative term of reference which directly implied that the word ‘sceptic’ was inappropriate, then refraining from the use of the word ‘sceptic’ at the same time! No net gain. They are continuing to use terminology which de-legitimises those who question CAGW, just in a slightly different way. I don’t believe Anthony should be giving kudos to AP in that respect, even less agreeing to abide by this stylebook change.
