Real Climate has done two posts recently that I thought would be served well by their juxtaposition. The first one highlights an early projection of global mean temperatures made by Jim Hansen in 1981. The abstract for that paper contains this choice quote: It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980's. These are both things that have in fact happened. I think it is safe to call this a very successful early prediction of…
From http://www.columbia.edu/~jeh1/mailings/2011/20110415_EnergyImbalancePaper.pdf. The email that pointed me at it said "Sincere apologies -- I am very sorry that I did not have time to write a shorter paper" and I think he is correct to apologise. It also says "Climate sensitivity section probably belongs in the paleo paper still under review" which also seems correct - to devote 15 pages (more than 1/4 of the paper!) to saying that Climate Sensitivity is ~ 3 oC is to confess that your prose is too prolix - and he doesn't even quote JA (which brings up another topic: he spends far too much…
As fate would have it, no sooner does a disengenous commenter here point out the unusual cold and snow falling on my hometown of Vancouver, Canada than I come accross this amusing comic from Jen Sorenson:
Roger puts up another post (guest post, gotta love plausible deniability) about James Hansen: blah blah blah....dictator who ordered millions of people to be gassed and then burned in crematoria...blah blah blah No, he isn`t (yet) calling Hansen a Hitler, but we all know how Godwin`s Law works. Or almost all of us... [UPDATE: Things Break has a stronger stomach than I do, and he takes a more thorough look at Roger's latest. As usual with Pielke's positions, the closer you look, the less it holds up.]
Over 12,000 people are expected at a student climate conference this weekend and today over one thousand will gather today in Washington DC. The focus of the DC protest is the local coal fired plant that powers capitol buildings heat and air conditioning. The target is symbolic, and congress has preemptively agreed to switch the plant to natural gas. But the most compelling reason to pay attention to this: Jim Hansen at NASA, [...] may be arrested today with us all We can all expect more of this from the attack dogs, of course. (BTW, when I went to that link, the Google Ad prominently…
Just a quick update on my recent post noting Roger Pielke's lack of integrity: Roger makes a note of my post and John Fleck's and adds this underhanded toss-off line: Hansen's forecast "did not survive the peer review process" and so did not "appear in PNAS". Of course, the alledged "prediction" of a super El Nino ("there is a good chance") from the draft was not submitted to PNAS for peer review. Roger is refering to Hansen's passing the draft to a few friends and colleagues, inadvertently distributing it more broadly (oops, Roger's not a friend!). There is a must read exchage at John…
I have made it pretty clear before that I am no fan of Roger Pielke Jr. Everytime I stick my nose in there the smell seems to get a little worse. His latest effort at sabotaging productive discourse on climate science and policy is a really low blow, putting to rest any lingering hopes one might have had that he still had some integrity stashed away in there somewhere. Now I know these are strong words, but I have to confess this really gets my blood pressure up, it is just the slimiest of tactics. (I will happily retract this post and apologize if Roger makes ammends for his ethical…
I found this YouTube clip via Crooks and Liars of James Hansen on Democracy Now. It also contains some highlights of other Democracy Now interviews, including one of Science Blogs' own Chris Mooney. He talks about the political muzzling he has experience under both parties during his time at NASA. (But don't the denialists tell us of collusion between scaremongering politicians and money grubbing scientists? Funny how the denialists tell us of collusion between scaremongering politicians and money grubbing scientists and yet the reality is NASA's earth sciences budget being cut and…
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection: In October, 2008, Al Gore's science advisor, James Hansen announced yet another "hottest" month on record. After all the alarmist banner headlines sank in, yet another "correction" quietly contradicted this, and October was not particularily warm after all. This is yet another example of why the temperature record can not be trusted. Answer: Wow. Where to begin with this one? There are many versions of this myth around already at the time…
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection: In 1988 Hansen predicted dire warming over the next decade and he was off by 300%. Why in the world should we listen to the same doom and gloom from him today? Answer: While it may well be simply ignorant repetition of misinformation in some instances, at its source, this story is a plain and simple lie. In 1988, James Hansen testified before the US Senate on the danger of Anthropogenic Global Warming. As part of that testimony he…
