The case continues to fascinate me. News on it over this side of the Atlantic is sparse, so if you have any nice links please put them in the comments.
The main outcome of the "tutorial" as I understand it was Chevron's lawyer essentially agreeing with the IPCC (for example, in their submission, the very first statement is “IPCC Fifth Assessment Report: It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.”). The other oil companies didn't speak, and have been given not-very-long to say whether they disagree with anything he said. I hope they make no substantive disagreements, because then finally we could have a discussion about GW in which the important point is not the science - which all sane people are agreed on, to the degree needed - but questions of responsibility and perhaps economics. This would also relieve the court of the tedium of having to read Monkers' or HKL's screeds. Or the latecoming nonsense from the "Concerned Household Electricity Consumers Council", aka an astroturf front for Joseph D’Aleo. What is it with these nutters?3
The Verge says "CHEVRON’S LAWYER, SPEAKING FOR MAJOR OIL COMPANIES, SAYS CLIMATE CHANGE IS REAL AND IT’S YOUR FAULT". That's rather foolishly phrased, as well as very shouty. It is also wrong: as far as I can see Theodore Boutrous was speaking only for Chevron2, and if he wasn't, Alsup's request would make no sense. The "it's your fault" bit is the point I've made many times before: "Fossil Fuel Companies Do Not Cause Carbon Emissions, We Consumers Do". I'm glad to see Chevron saying it in court, and it is fun to watch the Verge's head exploding as a concept that doesn't fit gets rammed home. Boutrous also (from the Verge; I can't find a transcript) appears to have sensibly tried to discuss exactly when the science was firmed up to the "well you really should have known it" stage. There's been a lot of deceptive PR about this recently, but I think they'll have no great trouble showing that even by the first IPCC report in 1990, attribution was at an early stage (in Chevron's presentation, the second substantive quote contains, in bold, Thus the observed increase could be largely due to this natural variability, which is from IPCC '90)1.
There are suggestions from the Daily Caller, Federal Judge Dismissed Claim Of A Conspiracy To Suppress Global Warming Science, but I'm dubious that is a WP:RS, and seems to be based on tweets. ClimateLiabilityNews provides a more nuanced Despite opening with a warning from Alsup “not to get political,” the tutorial ended on a political note. Boutrous referenced a paragraph in the plaintiffs’ complaint that accuses the defendants of colluding to suppress public information about climate change. “From what I’ve seen—and feel free to send me other documentation—but all I’ve seen so far is that someone went to the IPCC conference and took notes,” Alsup said. “That’s not a conspiracy.”
As you'd expect, the defendants have filed a motion to dismiss. Whether that's plausible or not, I've no idea. I suspect Alsup is having too much fun to just throw this away quickly, though.
1. From sciencemag, I find Speaking for the cities, Myles Allen, a physicist and climate scientist at the University of Oxford in the United Kingdom told Alsup the science was clear enough more than 3 decades ago to realize global warming would be caused by greenhouse gas pollution, even if measurements hadn’t definitively picked it up. “It wasn’t necessary for scientists in the late 1970s to detect the warming in order for them to predict what was likely to happen next as a result,” he said. I don't think that will fly. It would be unreasonable not to allow the oil companies to rely on the authority of the IPCC reports.
2. Ah good, The Graun confirms my memory: Boutrous was indeed just speaking for Chevron, and said so. Which makes The Verge's drivel even harder to understand.
Update: and indeed, the transcript says: "I'm here representing Chevron here today, and
I'll be presenting the tutorial on behalf of Chevron." So why the bald-faced lying from The Verge?
3. Happily, the nutters aren't happy with Chevron for throwing them under the bus. They are going to be even sadder in two weeks time when the other oil companies agree with Chevron.
