You Ought to Have a Look is a recurring feature from the Cato’s Center for the Study of Science that briefly highlights a few interesting blog posts from around the web that are comments on subject areas we are currently emphasizing. Climate change issues currently top the list. Here we post a few of the best in recent days, along with our color commentary. This is the first installment of You Ought to Have a Look
We start off with the estimable Judith Curry, former chairwoman of the highly regarded School of Earth and Atmospheric Sciences at Georgia Institute of Technology (aka “Georgia Tech”). Her musings, published every few days on her blog “Climate Etc.” have a wide following amongst climate geeks (like us), while oftentimes her postings should be of interest to a wider, more general audience.
Judith scored big last week with an excellent op-ed in the Wall Street Journal. In her subsequent blog post “My WSJ op-ed: Global warming statistical meltdown,” she takes you through the version that appeared in print as well as some of the earlier drafts of it highlighting lessons she learned along the way. The article focuses on her recent blockbuster publication in which she and co-researcher Nic Lewis peg the earth’s climate sensitivity—how much warming will occur as a result of a doubling of the atmospheric concentration of carbon dioxide—at a value about one-half that which is produced by the collection of “state-of-the-art” climate models used by the UN and the Obama Administration to underpin their calls to mitigate carbon dioxide emissions from the production of energy.
And nearly every Friday, she posts her “Week in Review” where she highlights things that have recently caught her eye or events that she was involved in. In the current issue, she describes her recent travels which included a trip to Ohio’s Oberlin College where she “debated” me (PJM). As she describes it:
The debate went fine, we each had 10 minutes to make opening statements on the science, and then an additional 10 minutes to discuss broader implications. I used my time to discuss the values issues and decision making under deep uncertainties. PJM discussed the increasingly perverse incentives in academia and government funded science, see [link] for some of his recent writing on this topic. He definitely makes some valid points.
Next, you might want to check out the witty Matt Briggs (“Statistician to the Stars”) post on “Don’t Say ‘Hiatus’” in which he takes us (and virtually everyone else) to task for using the terms “pause” and/or “hiatus” to refer to the past 18 years or so of no statistically significant overall change in the earth’s average surface temperature. Briggs’ main point is that since climate change models are so bad (unskillful), there is no reason for a priori expectations of the temperature behavior one way or the other. In other words, a “pause” from what?
Be aware that Briggs is a very twisty writer, often leading the reader down a path that takes a sharp turn further down his somewhat detailed essays. But there is always some gem to find at the end!
