Incredibly Accurate Climate Forecast For 2011

(no £33M supercomputer was harmed in the making of this blog)

  • All atmospheric, oceanic, glacial, geological and public-health phenomena with any kind of negative impact will be linked to (anthropogenic) global warming with no shortage of experts confirming how we’d known that all along, and of computer models showing how obvious those consequences have always been
  • No atmospheric, oceanic, glacial, geological and public-health phenomena lacking any kind of negative impact will be linked to (anthropogenic) global warming
  • Romm will continue his fishing expeditions, hoping this or that weather-related mass killing can be taken advantage of, in order to promote the concept of anthropogenic global warming
  • Hansen will get (willingly) arrested once or twice, ready to proclaim 2011 as the warmest year ever, mostly due to extremes of heat in faraway places devoid of people and weather stations
  • McKibben will get even thinner, and just as ineffectual, while identifying new enemies forever closer to himself
  • RealClimate will keep its absurdist censorship policy, and in post after post the Team will “demonstrate” their intellectual superiority
  • Skeptical Science will keep building climate salad surgeries to no end, sprinkling statements of various robustness with seemingly limitless references to the Literature, to be used by the lazy and most scientifically-ignorant among its readership (i.e. the journalists)
  • The Climate Change Rapid Response Team will say nothing of relevance that hasn’t been already said
  • The nastiest criticisms by rabid AGWers will be thrown in the direction of Curry
  • Revkin will keep reaffirming his absolute confidence in mainstream AGW science despite the evidence to the contrary presented in Revkin’s blog
  • Pielke Jr will be distracted by other things, thereby avoiding Revkin’s problem
  • The IPCC will make sure nothing really is changed in its procedures or results
  • McIntyre will be made privy to secret information showing how deeply unpopular in the mainstream climate community is anything remotely linked to McIntyre
  • Goddard (S.) will publish his 25,000th blog post
  • Goddard (NASA’s) will discover that recent thermometer readings must be adjusted upwards, and past ones downwards, for purely scientific reasons of course
  • Watts will be criticized (for being Watts and) for providing web space to people with strange theories
  • ScienceOfDoom will busy himself with explaining the first law of thermodynamics (again!) thereby missing all the fun
  • Connolley will not notice the rest of the planet
  • Tamino will pop up once around here and other places, posting an inane, canned comment that could be written in reply to any other blog post written by anybody on any topic
  • Some people with a very nasty mindset will suggest that the glowing comments to Tamino’s posts might as well have been written by people sharing the same identical DNA with Tamino
  • The recipient of the 2010 Edward Davis Wood, Jr.’s Climate “Blogging Turkey” Award will sink to new lows
  • The art of obfuscating FOI and non-FOI answers will be perfected by the CRU and the BBC
  • Popular media will be filled by photographic reports about a changing climate, with no picture showing anything remotely connected to climate change in a proper scientific way
  • Popular media will be filled by countless breakthroughs in climate science showing how worse it is than we thought
  • Scientifically speaking, there will not be any breakthrough in climate science
  • A very large number of well-known and otherwise knowledgeable scientists will make complete asses of themselves by appearing on TV and in print with idiotic regurgitations of mainstream AGW theory, mostly inconsistent with the very statements made by the IPCC
  • If the weather will keep cold, a major European scientific institution will break ranks with mainstream AGW theory before the summer
  • Popular interest will wane as most people will be titillated about the 2012 “end of the world” instead
  • The EU will find new ways to use climate change to transfer money to the rich, and to China
  • China will happily go along the EU cash-transfer schemes
  • The US Congress and President will strike a united front in protecting climate-change-related pork (money not meat)

And finally for the real world…

  • It will rain, otherwise it will be sunny, foggy, cloudy or overcast. It will snow in places, with sandstorms in other places (or the same ones). It will be cold, then hot, then cold again, or viceversa more or less overall. Some droughts, some floods, and places experiencing drizzle. Unprecedented weather will be experienced for the 200,000th year running, with lack of morals among humans indicated as main culprit for the 200,000th time as well
  • Many people will die of poverty in weather-related events around the world, with the keys being “poverty” and “weather” but all action concentrated on “climate change”
  • Children will keep dying of soot, while the world concerns itself with CO2 emissions only
  • Elderly people will keep dying of fuel poverty, while the world concerns itself to increase fuel prices in order to reduce CO2 emissions

IPCC Amazongate: "A Complete Load Of Porkies" Indeed

ADDENDUM JUL 13: Christopher Booker has managed to trace the 40% claim to a deleted web page. “Neither WWF nor Woods Hole come well out of this story“.  Definitely, they do not. See also EU Referendum.

ADDENDUM FEB 15: Daniel Nepstad has posted a statement endorsing “the correctness of the IPCC’s (AR4) statement on Amazon forest susceptibility to rainfall reduction” (link fixed on JUL 13). But Nepstad makes several references to 2004 and 2007 articles whose existence the IPCC authors were not obviously aware of. If the IPCC has been right for the wrong reasons, we can state it has been wrong: because it cannot simply be a matter of having it right by pure chance.

(I have posted a version of the below as a comment at WUWT, concerning James Delingpole’s “After Climategate, Pachaurigate and Glaciergate: Amazongate” and in the response to the following comment by an “Icarus” (Jan 25, 14:19:23):

It appears that the 40% figure references this passage in the WWF/IUCN report:

“Up to 40% of the Brazilian forest is extremely sensitive to small reductions in the amount of rainfall. In the 1998 dry season, some 270,000 sq. km of forest became vulnerable to fire, due to completely depleted plant-available water stored in the upper five metres of soil. A further 360,000 sq. km of forest had only 250 mm of plant-available soil water left.”

This passage references a peer-reviewed article in Nature:

46 D. C. Nepstad, A. Veríssimo, A. Alencar, C. Nobre, E. Lima, P. Lefebvre, P. Schlesinger, C. Potter, P. Mountinho, E. Mendoza, M. Cochrane, V. Brooks, Large-scale Impoverishment of Amazonian Forests by Logging and Fire, Nature, 1999, Vo l 398, 8 April, pp505

Unfortunately I don’t have access to the full article but to call this reference “a complete load of porkies” seems a bit unjustified, unless it can be shown that Rowell and Moore completely misrepresent the Nature article (which of course *is* written by Amazonian specialists).

)

The expression “a complete load of porkies” for what ended up in the IPCC AR4 WG-II Chapter 13, seems a bit justified indeed.

First of all it should not be up to the reader to dig down in the IPCC references until anything peer-reviewed is finally found. If Nepstad et al 1999 were the primary source for the “Up to 40%” claim, that article should have been used, stated and referenced as such, no matter what Rowell and Moore understood of it.

Secondly, the IPCC AR4 WG-II Chapter 13 makes no mention of Nepstad et al 1999. As far as I can see, the Nepstad et al 1999 article is only used in AR4 in the IPCC AR4 WG-II Chapter 4:

(1) p228

Recently observed moderate climatic changes have induced forest productivity gains globally (reviewed in Boisvenue and Running, 2006) and possibly enhanced carbon sequestration, especially in tropical forests (Baker et al., 2004; Lewis et al., 2004a, 2004b; Malhi and Phillips, 2004; Phillips et al., 2004), where these are not reduced by water limitations (e.g., Boisvenue and Running, 2006) or offset by deforestation or novel fire regimes (Nepstad et al., 1999, 2004; Alencar et al., 2006) or by hotter and drier summers at mid- and high latitudes (Angert et al., 2005)

(2) p229

in some tropical and sub-tropical regions, notably South-East Asia and similarly the Amazon (e.g., Nepstad et al., 1999), deforestation rates are still high

You may note that in both cases Nepstad et al 1999 is used to mention deforestation (something one might expect out of an article titled Large-scale Impoverishment of Amazonian Forests by Logging and Fire).

The abstract of that article is particularly terse on Nature.com:

Amazonian deforestation rates are used to determine human effects on the global carbon cycle and to measure Brazil’s progress in curbing forest impoverishment,,. But this widely used measure of tropical land use tells only part of the story..

For some reason, there is a longer version on Mendeley.com:

Amazonian deforestation rates are used to determine human effects on the global carbon cycle(1-3) and to measure Brazil’s progress in curbing forest impoverishment(1,4,5). But this widely used measure of tropical land use tells only part of the story. Here we present field surveys of wood mills and forest burning across Brazilian Amazonia which show that logging crews severely damage 10,000 to 15,000 km(2) yr(-1) of forest that are not included in deforestation mapping programmes. Moreover, we find that surface fires burn additional large areas of standing forest, the destruction of which is normally not documented. Forest impoverishment due to such fires may increase dramatically when severe droughts provoke forest leaf-shedding and greater flammability; our regional water-balance model indicates that an estimated 270,000 km(2) of forest became vulnerable to fire in the 1998 dry season. Overall, we find that present estimates of annual deforestation for Brazilian Amazonia capture less than half of the forest area that is impoverished each year, and even less during; years of severe drought. Both logging and fire increase forest vulnerability to future burning(6,7) and release forest carbon stocks to the atmosphere, potentially doubling net carbon emissions from regional land-use during severe El Nino episodes. If this forest impoverishment is to be controlled, then logging activities need to be restricted or replaced with low-impact timber harvest techniques, and more effective strategies to prevent accidental forest fires need to be implemented.

It is hard not to notice that Nepstad et al 1999 were concerned about deforestation and fires possibly exarcebated by severe droughts, whilst Rowell and Moore, and the IPCC authors and reviewers, completely turned the cards around, pushing hard on the climatic side first.

That is not the first time I have seen “Chinese whispers” at play in the IPCC AR4

About Yamal

Non-casual readers already know I do not like to dwell into topics covered in great depth elsewhere. I will make a very short exception to that “policy”, simply because the McIntyre/Briffa story is too big.

Too big, that is, not to warrant some huge dose of skepticism before getting carried away with it.

We have a saying in Italian, “if they’re roses, they’ll bloom”. AKA “time will tell”.

As much as I admire McIntyre’s relentless quest to go always back to the original data, I am sure I am not the first one that has seen apparently-straight forward things turn around all of a sudden. There’s no reason to celebrate… if the Briffa reconstruction will implode, it will implode anyway.

Now we have a blog on the topic, by Gavin Schmidt at RealClimate, and a brief note by Briffa himself.

Gavin is his usual self, the worst enemy of AGW that is, with a blog post choked by its own sarcasm. Through the deep, rather undignified fog, one can get a glimpse of what appears to be a potentially strong riposte to Steve McIntyre (but with Schmidt’s emotions running so raw, I am afraid McIntyre will always have the upper hand).

Briffa is very calm and measured, therefore making his decision not to share the data sooner even more puzzling

Right now, it looks like there will be a “war of words” with claims and counterclaims. On that, I have no interest whatsoever. And too many people already are “jumping in” in ways that can only dent their credibility.

I might come back to the story after the battle. For now, this is my comment at RC:

Kudos to Briffa for having decided to “review the details of [McIntyre’s] work”.

Is it too much to state that most of what has happened, would not have happened had the data been made available upon (first) request?

On that topic, I believe that NASA changed its policy regarding space probes a decade ago or more, in order to avoid (crackpot) accusations of being in the business of airbrushing aliens out of the photos. That is why mission websites like MER’s _prominently_ show the just-received “raw images”, especially in the first days of the mission (please correct me if I am wrong).

Wouldn’t it therefore make sense to apply the same rules to all just-published papers, i.e. presenting the “raw data” to the visitor, rather than simply leaving it “available for anyone who cares to look”? Especially in a field such as climate change, where any accusation/finding is bound to elicit plenty of reaction.
