Hot news, evolution cools!

Steve McIntyre has the scoop: According to the University of Victoria, Andrew Weaver says: the next generation of his climate model will address the influence of climate on human evolution—much like it’s now being used to examine the influence of humans on climate evolution”. In breaking news, Climate Audit has obtained exclusive information on output from the…

A call to action – give #ClimateThanks

Another Internet campaign that could go horribly wrong… Tom Nelson advises me that the Yale Project on Climate Change Communications decided to prod readers into giving “Climate Thanks” this Thanksgiving on Twitter. A silly idea for sure, but certainly better than advocating eating “tofurkey” to lessen climate change. I’m sure WUWT readers have lots to…

The 97% consensus myth – busted by a real survey

We’ve all been subjected to the incessant “97% of scientists agree …global warming…blah blah” meme, which is nothing more than another statistical fabrication by John Cook and his collection of “anything for the cause” zealots. As has been previously pointed out on WUWT, when you look at the methodology used to reach that number, the…

Stephan Lewandowsky’s ethical lapses allowed his science to be published without oversight

As if there could be any more ludicrous antics from this plonker, we now find that Dr. Stephan Lewandowsky pulled a bait and switch on ethical approvals for his psychological research papers at the University of Western Australia that were designed from the start to smear climate skeptics. It’s so unreal, it can only be…

The WUWT Hot Sheet for Sept 26th, 2013

From Steve McIntyre: Two Minutes to Midnight There is much in the news about how IPCC will handle the growing discrepancy between models and observations – long an issue at skeptic blogs. According to BBC News, a Dutch participant says that “governments are demanding a clear explanation” of the discrepancy. On the other hand, Der Spiegel…

The East Anglia Rococo

Steve McIntyre has a new analysis up, one that has a strong headline. Though as he says, “not in so many words”, but more about techniques and exclusions. He writes: Briffa Condemns Mann Reconstructions

Briffa, Yamal, reputational damage, and all that

Keith Briffa has just published a new paper using the Yamal-Urals regional chronology data, something long sought after via FOIA requests. That data was withheld, citing it wasn’t cooked done with yet, and that releasing it would damage the reputation of CRU scientists. After Climategate in 2009, I’m not sure how CRU’s reputation could be…

FoS CliSci Summary

Climate Science Newsletter Crowd sourcing A unique effort to assemble a large number of paleo-temperature graphs on all time scales was made earlier on the WUWT Paleoclimate Reference Page and is now continuing with a recent posting (March 30th). ————————— Fixing the Marcott mess Recent issues of CliSci have dealt with the Marcott-Shakun 2013 paper…

McIntyre charges Grant Foster aka “Tamino” with plagiarism in a Dot Earth discussion

Reader “pottereaton” submitted this on 2013/04/01 at 2:28 pm McIntyre/Tamino Feud brewing: First McIntyre at DotEarth: Steve McIntyre Toronto, Canada Andy, The ideas in Tamino’s post purporting to explain the Marcott uptick,http://tamino.wordpress.com/2013/03/22/the-tick/ which you praise as “illuminating”, was shamelessly plagiarized from the Climate Audit post How Marcott Upticks Arise. http://climateaudit.org/2013/03/15/how-marcottian-upticks-arise/ It’s annoying that you (and…

The Pitfalls of Data Smoothing

Guest Post by Willis Eschenbach Since we’ve been discussing smoothing in datasets, I thought I’d repost something that Steve McIntyre had graciously allowed me to post on his amazing blog ClimateAudit back in 2008. Let me start by saying that when I got involved in climate science, the go-to blog was the late, great John Daly’s…

Dr. Michael Mann, Smooth Operator

Guest Post by Willis Eschenbach People sometimes ask why I don’t publish in the so-called scientific journals. Here’s a little story about that. Back in 2004, Michael Mann wrote a mathematically naive piece about how to smooth the ends of time series. It was called “On smoothing potentially non-stationary climate time series“, and it was…

A Conspiracy of One

Guest post by Brandon Shollenberger Words cannot describe the humor of Michael Mann’s latest post: As professional climate change deniers become increasingly irrelevant and desperate, so do their distraction and smear efforts. These are mostly just noise in the background these days, as the media increasingly appears to be recognizing the intellectual bankruptcy of the…

Michael Mann’s new ‘trick’, pulled off at the American Geophysical Union Convention – exposed by McIntyre

Mike’s AGU Trick By Steve McIntyre There has been considerable recent discussion of the fact that observations have been running cooler than models – see, for example, Lucia’s discussion of IPCC AR5 SOD Figure 9.8 (see here). However, Michael Mann at AGU took an entirely different line. Mann asserted that observations were running as hot or…

About Climate Audit

UPDATE: I’m happy to report that Steve writes in with an update on the tragic accident that sent him to New Zealand. It is good news. – Anthony UPDATE2: Steve asked me to intervene, saying he had issues with the renewal of the domain. I intervened with the domain registrar last night, paid the outstanding…

Mann’s hockey stick disappears – and CRU’s Briffa helps make the MWP live again by pointing out bias in the data

Shock, awe. Untruncated and unspliced data used in a new paper from Briffa and Melvin at UEA restores the Medieval Warm Period while at the same time disappears Mann’s hockey stick. Here’s figure 5 that tells the story: Look at graph 5c, and you’ll see 20th century warmth matches peaks either side of the year…

Gergis et al hockey stick paper withdrawn – finally

Between this withdrawal and the Esper et al paper showing the MWP and RWP warmer than today, Mike Mann must be having a really, really, bad day. Even SuperMandia in tights can’t help. Thanks to Richard Tol (and Marc Morano) for this tip: Readers may recall Steve McIntyre’s evisceration of Gergis et al. Steve’s question…

Lewandowsky’s bait and switch

More on the now infamous “moon landing denier“” statistical paper. Question – how did this title for a scientific paper: Understanding Statistical Trends Turn into this? NASA faked the moon landing|Therefore (Climate) Science is a Hoax: An Anatomy of the Motivated Rejection of Science Easy. You get ethics approval from your university for the first…

The ‘secret’ IPCC Stocker WG1 memo – found!

You may recall that WUWT reported this on Sepetember 6th, 2012: Game on – NOAA’s refusal of documents earns them a lawsuit Over the last couple of days, CEI’s Chris Horner has been emailing me news of a FOIA request he made earlier in the year. The FOI request is for correspondence between NOAA’s Dr. Thomas…

The Lewandowsky participation question

UPDATE: There are so many respondents (thank you) and since it is clear that about 97% of WUWT readers hadn’t seen/participated in 2010 Lewandowsky survey, that we’ve added a second thread to get the most important part of the data. You can still record your participation/non-participation below in the question form, but if you DID…

The Daily Lew – Issue 4

LewWorld still has no comment of substance, and in the ‘Skeptical Science’ style, is furiously deleting inconvenient comments that ask questions like “What are you going to do now that the removal of the fake responses shows a conclusion reverse of that of your title”? Jo Nova finds that Lewandowsky has received $1.7 million AU…

The Daily Lew – Issue 3

LewWorld is a busy place these days. Claims of conspiracy theory are supplemented with even more claims of conspiracy theory when some obvious flaws to data and methodology are pointed out, like faked responses. Faked responses abound in the Lewandowsky “moon landing” paper because there were not any adequate quality controls. Further compromising the data…

The Daily Lew – Issue 2

More noise in Stephan Lewandowsky’s LewWorld. This time, Steve McIntyre finds a statement by Lewandowsky that effectively hoists him by his own petard. Apparently, data integrity only applied to others, not the inhabitants of LewWorld. Steve writes: Lewandowsky has stated that an online survey by an opponent was “useless” “without the authors demonstrating the integrity…

McIntyre’s talk in London – Plus, the UK’s tilting at windmills may actually increase CO2 emissions over natural gas

At The Register, Andrew Orlowski attended the talk and has a news article describing Steve McIntyre’s talk at the Institute of Materials, Minerals and Mining, which was an event hosted by the Global Warming Policy Foundation. McIntyre’s statement on wind power is interesting: The entire rationale of policy in US and Europe has been to…
