Ken Lambert at 22:40 PM on 1 June 2011The Critical Decade - Part 2: Climate Risks
Steffan, Flannery and Karoly are trotting out the standard version of AGW alarmism based on the last 30 years of warming temperatures, rising sea levels and other 'multiple lines of warming evidence'. As usual, the vast uncertainties of climate prediction are dwarfed by the big scare of tidal surges and abandoned cities. Trouble is that the last 10 years of climate measurement is not following the AGW script. Surface temperature rise is flattening, Sea level rise is dropping below the touted trend line of 3.1mm per year, and the warming imbalance measured by ocean heat content is flattening, by some measures down by at least 30% and by others - actually cooling. Jim Hansen (AGW guru and lead IPCC author) has recently written a 52 page synopsis which finds a reduction in the warming imbalance from 0.9W/sq.m to 0.59W/sq.m which he mainly attributes to substantial underestimated cooling due to aerosols. His explanations of other factors are highly contentious, including a preposterous 'delayed Pinitubo rebound effect', however the import of his conclusion is the sleeper in this debate. Jim Hansen has abandoned the 'its there but we can't measure it yet' explanation of Dr Trenberth's missing heat travesty, and recognized that at least 30% of the warming 'trapped heat' in the oceans - ain't there at all.Response:[dana1981] Please stop cherrypicking the last 10 years. Moreover, Trenberth has a draft paper out where he suggests the location of the 'missing heat':
"Based upon a number of climate model experiments for the 21st century where there is a stasis in global surface temperature and upper ocean heat content in spite of decade long periods with a known net energy input into the climate system, we infer that the main sink of the missing energy is likely the deep ocean below 275 m depth."

Bob Lacatena at 22:36 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
(Correction to 112... I meant to say that anyone saying sensitivity is in the 2-4 range is explaining or re-iterating the science). -
Bob Lacatena at 22:33 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
104, Utahn, 109, Eric, There is a big, big, almost insurmountable difference between saying that 2˚C is at the low end of a range, and saying that climate sensitivity is likely to be 2˚C. Anyone who is counting on 2˚C is in denial. Anyone who is saying that sensitivity is likely to be in the range of 2˚C-4˚C or 2˚C-5˚C is in denial. Giving credibility to those who put forth 2˚C as a likely outcome is very unproductive. It's a (fallacious) argument for BAU. -

Thank you for your insight adelady. I admit to being more influenced by the end era were anti-military was more prevalent and free sex and drugs was rampant (I attended the University of Michigan in the 70s). -
L.J. Ryan at 21:54 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
The more appropriate name for this blog post should be Divide and Conquer. Those whom accept GHG physics and data, the reasonable skeptics, need only be convinced of the sensitivities the margins...an easier argument. The others, the "Head in the Sand" type the DENIERS...they need be singled out for ridicule. Those stateside will recognize this same tactic employed by the political left to avoid meaningful debate. This readers, is the Saul Alinsky approach to science. Ironically, the simple fact John Cook deems it necessary to pose the question: Are you a genuine skeptic or a climate denier? is evidence the only thing melting is once solid support of AGW. ( -Ideological diatribe snipped- )Response:[DB] Please refrain from the use of all-caps and keep the focus on the science, not on politics and ideologies.

RyanStarr at 21:37 PM on 1 June 2011Ljungqvist broke the hockey stick
@dana1981 (+others), as you say Ljungqvist ends at 2000, I thought roughly that but with such a long time frame it's hard to be sure (so not 1950 CBD). At the year 2000 it's just a smidgeon above 0, close to 0.075. The Hadcrut overlay, for the next 10 years, rises a further 0.7 degrees, in 10 years it rises 0.7 degrees!Something has to be in error here. OK Ljungqvist is a reconstruction so we expect the accuracy of that to fall well below an instrument record, are we saying Ljungqvist's late 20th century result is in error by up to 0.7 C?
Moderator Response:[dana1981] The error is that your "10 years" is more like 30 years. Each yellow dot represents a new decadal average. Some of the red data is included in Ljungqvist's study, but he omitted the final data point.

les 108 The "present" goes beyond subjectivity, as it is tied to one's inertial frame of reference. All people on Earth experience this "present historical moment" simultaneously for all practical purposes, however I am technically correct in my statement. It was Glenn Tamblyn who described our natural "anthropocentric view of the Universe" as being archaic, when in fact it is innate and as real as the CO2 we all breath. -
Eric the Red at 20:44 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
Utahn, I agree. To label someone a denier because they believe the cliamte sensitivity is closer to 2C than 3C is absurd given the large uncertainty and range of sensitivity values. Here is a paper which seems to discount the possibility of high sensitivity (>4.5). http://www.jamstec.go.jp/frcgc/research/d5/jdannan/probrevised.pdf Funny how the both of us were believed (by other posters) to adhere to a climate sensitivity of 2C just because we would not call them deniers. I looked back at both of our posts, and found nothing that would indicate that either of us adhere to that value, only that we cannot eliminate it from the range of probabilities. Personally, I agree with your assessment of name calling, and will reserve the term, "those in denial" for those who actually think the climate sensitivity is zero. -
okatiniko at 20:40 PM on 1 June 2011The Critical Decade - Part 2: Climate Risks
Adelady, you may believe that the welfare of your grandchildren will be absolutely different following the SLR rate (does it mean that you believe that your own welfare would have been totally different if the SLR would have been, for instance, 6 mm/yr, so 6 cm/decade instead of 2 , in the XXTh century ? how would your own life have changed ?) However what I said is that it is clear from figure 15 that the SLR will be pretty insensitive to any policy we could adopt - the uncertainty ranges largely overlap and the increase will continue for centuries if Rahmstorf model is true. Meaning that the SLR is already in the pipe and, even we stopped totally now any GES emission, it would continue rising and reach one meter around the turn of the century. The differences between the scenarios being only about one decade or so. So it is actually pretty much like a natural phenomenon that you cannot. Whatever you think it will cause, you'd better prepare your children by telling them it will happen anyway. Now I doubt very much that all infrastructures you can see around you will be unchanged at the end of the century. And cutting off the use of fossil fuels will probably change much more your way of life than a few dozens of centimeter of water on the coast. You live in a huge country : do you have any idea of how travelling across it without oil for instance ? that would be a huge change !Response:[dana1981] Sea level rise is far from the only consequence of climate change. As Thompson has said, there will be some degree of mitigation, adaption, and suffering. The less we mitigate, the more we will have to adapt and suffer.

Rob Painting at 19:36 PM on 1 June 2011Amazon drought: A death spiral? (part 2:climate models)
Alexandre @ 6 - Southern Amazonia will dry out according to most models, because the dry season intensifies and becomes longer. But heavier downpours are expected too. Sorry for the bad news, but they are projections, and might be missing some important details that change the overall picture. -

RSVP at 18:12 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
Glenn Tamblyn 61 "The last vestiges of the Anthropocentric view of the Universe reside in the conservative, individualist personality type." Relativity suggests that each person is the center of his own universe. As there might be some truth to AGW, this is not the problem. It comes as a package deal, "deniers" being all those who are not with the program. Thanks to Nature however, humans were created with that individualistic spirit you so much distain. -
adelady at 18:03 PM on 1 June 2011The Critical Decade - Part 2: Climate Risks
okatiniko, it's not just where people 'live'. It's where important infrastructure that supports people who live all over a city's region. The 3 biggies, apart from the obvious one of port facilities both for freight and for fishing fleets, would be sewage processing plants, power plants using ocean water for cooling and airports established on flat land near coasts. Less frequent local effects would be saltwater intrusion into groundwaters and wetlands as well as further upriver in some locations. "... your life has nothing in common with your grandparents' one." I beg to differ. In all the important things, my life is a lot like my grandparents. My main interest, as was theirs, is the welfare of my children (and their children). I use technology they never dreamt of, I've never lived through a world war waiting for husbands or children to return, and I don't attend church every week. But people are just people. My concern for my family, my friends, my neighbourhood and society at large is very like the concerns of previous generations. Hopefully, coming generations will have the same chances I had - rather than the ghastly privations of worldwide wars and worldwide depressions of my parents and grandparents. -
Dikran Marsupial at 17:45 PM on 1 June 2011Amazon drought: A death spiral? (part 2:climate models)
Michael Hauber The trend you plot is not robust, for example the 1974-2009 plot has a warming trend in the Pacific:Having experimented with the plotting software, the results depend strongly on whether the start and end years were El-Nino's or La Nina's or somewhere in the middle. The difference between two years is not a robust estimator of a trend.

Nick Palmer at 17:37 PM on 1 June 2011The Critical Decade - Part 2: Climate Risks
Okatiniko at #4 People can adapt to a lot. They can adapt to living in a tornado zone. They can adapt to living in earthquake zone. They could adapt to living in a zombie apocalypse. So what? Why should we have to? What appears to be your underlying denialism ignores the blindingly obvious fact that it would be breathtakingly stupid to pursue a course of inaction that brings about a nasty situation that we would have to "adapt" to, that we could avoid by taking action. Only an in idiot or denier could foresee something bad happening and do nothing to stop it manifesting. -
scaddenp at 16:18 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
Hmm, looking at previous comments I'd say you were resting your ideas on faith not science. What's the future evidence at which you would decide that you were mistaken instead? For how long do the predictions have to hold? (it's 35 since first model prediction and that holding okay). -

Riduna at 16:03 PM on 1 June 2011The Climate Show Episode 13: James Hansen and The Critical Decade
In this Episode of the Climate Show, lack of government support for reduction of greenhouse gas emissions was noted. A comment was made to the effect that the Prime Minister when told of the harm caused by GHG emissions had responded by saying he could produce scientists who would refute that GHG emissions were dangerous. Has the Prime Minister been challenged to produce a scientist who can substantiate that Global Warming is not caused by GHG emissions arising from human activity. Why has the PM not been publicly challenged by NZ’s climate scientists to produce a single scientist who can offer proof which has not already been shown to be wrong? It is all very well to lament that NZ does not have the equivalent of the Australian Climate Change Committee – but does that prevent NZ climate scientists from forming their own Climate Change Council? Does it prevent such a Council from making statements calling for government action, warning of the consequences of not doing so, discrediting and proving statements of deniers to be wrong? -
okatiniko at 15:34 PM on 1 June 2011The Critical Decade - Part 2: Climate Risks
It is certainly alarming since the projections of SLR show that it does depend only very weakly on the scenario, and that's because the acceleration term described by Rahmstorf et al. is a very long term one and is quite insensitive to the details of the future evolution of GES emission.In other words it is already set up now. But we have to keep in mind that in 100 years, most of the current infrastructures won't exist anymore. Which part of Sydney or Perth did exist 100 years ago ? But very strangely, you seem to think that people will keep living in those parts of the country that will be flooded "almost every month" . But just think of what "flooded every month" really means : it is just the part of the coast that is flooded at each high tide (actually twice a month) ! and it already exists everywhere. Nobody leaves here, or if we really want to live there, we just build some levees to protect the place. And the new building are not really a cost since they will be build anyway in all cases. Why would people living in 100 years be unable to do the same reasonable things as we do now ? humanity has always adapted to varying conditions, including SLR that exists since the end of glaciations. It has adapted to huge changes of way of life since the beginning of industrial civilization - your life has nothing in common with your grandparents' one. Do you think that your current life would have been absolutely impossible if the SLR would have been twice or three times as high as what it has really been in the XXth century ? why ? -

Thanks for the link, Alexandre. I'll check it out after this post. Eric, yes, I thought of that, too. Is there a way to amend the idea to account for publishing abilities/re-published papers, etc, that a skeptic would find acceptable? Even if the cluster was centred outside consensus values, at least the extreme outliers would still be isolated (I suppose). A temporal x-axis, like the graph in the top post, would also show how the science has developed. In the climate sensitivity example, the bars would shorten (I suppose) as ranges become more contained over time. A short-hand way of showing diminishing uncertainty - on most, but not all topics. -
Charlie A at 15:10 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
@103 Adelady says "my reading is 40-60 years for 'fast'" ... "Long-term? 100 years more than that." The fast response is at 2000 year after CO2 increase. 40-60 years is definitely fast, as is 160 years. The 3C "fast" response quoted by Michael Sweet in #91 is only fast compared to geologic time scales such as CO2 removal by the weathering of rocks. The GISS-ER model transient sensitivity after 70 years is 1.5C/doubling of CO2. http://ipcc.ch/publications_and_data/ar4/wg1/en/ch8s8-6-2-3.html -

Utahn at 14:44 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
Boy, I wish I hadn't been unable to get back to this until now, because I probably could have spared folks some trouble. Sphaerica:"There is no middle ground, let alone 24 flavors of middle ground." I disagree and find it's useful to at least to myself categorize deniers - it helps me to understand the best approach to discussion. I still think there is hope in discussion with many. "Second, I personally think (and by 'think' I mean that everything that I've read and understand about) your own adherence to a mere 2˚C per doubling as a likely or even reasonable possibility is another form of denial. The current consensus is 3˚C or higher, and every new study confirms this while leaning towards the 'and higher' direction. There is very little reason to think that 2˚C per doubling is in the mix. Expecting 2˚C is denial." I do not personally "adhere" to 2˚C. I was just laying out a person's stated climate sensitivity below which I am going to say denial begins. To me 2˚C is perfectly reasonable as a lower bound to label someone "denier", and is the same as the lower bound of the AR4 estimate of climate sensitivity, and with a few papers even recently (look at BPLs chart by time of major GCM estimates for example). Are you all saying 2˚C is not a reasonable *lower bound* for sane discussion of climate sensitivity to doubling CO2? I'm sorry if my initial post was not clear, but I did say "less than 2"! Honestly I'm sorry I even mentioned this, in any case after rolling it around on my tongue I'm not sure I like the word "denier" after all. It is, naturally, name calling. Accurate name calling, but still name calling. From now on I am going to use the more cumbersome, "those who are in denial of the science of climate change" or "those in denial" for slightly shorter. It feels like less of an indictment of the person, and implies my stated belief that some (certainly not all) of those in denial will not always be in denial. -
adelady at 14:33 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
@92, Charlie "Over what time period do you think Hansen meant when he discusses "fast" climate sensitivity?" Didn't find anything explicit on a quick look (obviously too quick) but my reading is 40-60 years for 'fast'. The common reference to 'in the pipeline' and that current warming is the consequence of CO2 from the 70s. Long-term? 100 years more than that. -

Tom Curtis at 14:12 PM on 1 June 2011Video on why record-breaking snow doesn't mean global warming has stopped
seeker25801 @35, according to the people most in the know, global warming is almost certainly occurring, and it is very highly probable that human activities are the major cause. Whether you think they are telling the full story or not, it is certain they know the full story better than anybody else on Earth. So the question you should be asking, seeing you so strongly disagree with them, is what is it that they know that you do not? If you read the arguments on this site, you will find out, for contrary to your insinuation, the climate scientists, and this site do tell the full story, so far as it is known. -
KR at 14:11 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
J. Bob - "One might also look at who is doing the articles/papers/data, and who is supplying the $’s." That is indeed one of my criteria, J. Bob. Is the data coming from a reputable scientist who regularly publishes peer reviewed works that are well received? Or is the work coming from a "think tank" or other advocacy group, such as the George Marshall Institute, GreenPeace, or the like (particularly from ones who do not disclose their funding)? Because if it's coming from a grant funded scientist, the likelyhood that it's driven by political influence is fairly small. Whereas if it comes from an advocacy group it's inherently biased - towards the positions the group advocates - not driven by the actual science. That is, after all, why advocacy groups exist. Advocacy groups works, data, and conclusions are therefore inherently less credible. -
KR at 14:05 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
J. Bob - Your reference to climate4you was, indeed, fascinating. Majority of plots 1979 on only, very few instrumental records prior to that, most of those from local areas. Heavy focus on GISP2 (a single ice core, not a global temperature), several Central England temperature records (hmm, seeing a pattern here?), statements such as ""net changes since 1998 appear to be small" (see Did global warming stop in 1998, 1995, 2002, 2007, 2010?)... Given the cherry-picking and short term focus, I don't know that I would trust the data or the presentation thereof from that site. It doesn't meet my requirements for presenting all of the data, avoiding cherry-picking, or using realistic periods of time for determining climate trends. I would not consider that a good resource - go to the peer reviewed papers! -
Bob Lacatena at 14:02 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
J. Bob, I'd also point out that there is a very clear comments policy, which is listed absolutely all over the place, and usually moderators provide warnings. People must be repeat offenders. Even then very, very few people are actually banned (like I am from WUWT). They are warned, and when they continue to violate the rules, their gibberish... not anything scientific, just the gibberish... is slashed. WUWT is the wild west, with one sheriff in town. He deletes what he wants, and you never see the stuff that's deleted. Here, there is a rhyme and reason to what happens. There, it is at the whim of Lord Watts. And I would also point out that I have had comments edited by moderators here. The rules are the rules. They apply to everyone. They're just broken far more frequently by deniers, and usually those same deniers are so lost in the science that they can't even see that they're breaking the rules. -

adelady at 13:58 PM on 1 June 2011If It's Not Sex, Drugs, and Rock 'n Roll, what is it? Creativity maybe?
Eric "...it was directed at any policy that inhibited freedom." I'm more mature (OK, older) than you, and my reading of the times was that it was about personal freedom. Being young people in the main, that was about Sex, drugs and rock'n'roll, but it was also about the freedoms denied by corporate and government restrictions on personal behaviours and circumstances. Denying jobs entirely on the basis of race and gender, paying less on the basis of race or gender, and sacking for things like women marrying or anyone divorcing. And conscription is not a favourite item for those wanting personal freedom to choose. Speaking to the 5 years 'more mature' member of this household, his view is that the movement was anti-capitalist and anti-military rather than anti-state. 'Our government should change' rather than 'We want no government at all'. You might be more influenced by the extreme ends of the general movement in much the same way as many women don't identify as feminists because their image is of the 'overalls and no lipstick' very public extreme end of that movement. All you need to do is to juxtapose an hour of the music of The Beatles or The Beach Boys or Jimi Hendrix and an hour spent reading Ayn Rand. (I never managed the whole hour, let alone the whole book. The afore-mentioned older person said he found the whole book amusing, he saw it as a kind of self-parody.) The idea that we of that liberal-minded generation wanted libertarianism in the untrammelled corporate power facing hamstrung, limited government style is just not true. We didn't like the "Little boxes on the Hillside" lifestyle, that's true. We wanted attention, and money, for the issues of poverty, injustice, violence, pollution - all of which require better government, not no government. Just as now. -
Bob Lacatena at 13:56 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
88, J. Bob,...and who is supplying the $’s.
This is the sort of conspiracy nonsense that shows when someone has no hope of understanding the science. If you honestly believe that some guy who's making $50K or $75K a year to spend half of his life trudging through the Arctic or the Amazon, or hoping to write a paper that will get him noticed for a few years among his peers, with a maximum attainable salary after that success of merely exactly what he's making now... because contrary to conventional wisdom, winning a research grant does not pay for a new Ferrari for each of the head researchers. Researchers get paid a salary by their universities, are expected to teach, and to do research and publish. They get research grants to go towards equipment and assistants to allow them to continue to pursue viable research. If they don't get grants, and publish, and teach, and work, then they fail. A career in science is not a stepping stone to babes, bucks and fame. "Who is supplying the $s" is a joke. My daughter was listening to a documentary today that went on and on about how coal is "Americas energy" that creates jobs and is crucial to the economy. That's where the money is going... not into research and science, but into propaganda. You're right about looking at the money, though. Is it coming from and going to real research, just as is done in agriculture and medicine and biology and most other branches of science, or is it coming from an energy industry with an agenda and trillions of dollars of income at stake, and going into propaganda? -

J Bob:If a site has to delete items based on scientific analysis, and interpretation of said results, it shows it's true biased colors, and demonstates their position is on shaky ground.

Then 50 people start calling me names, and any post defending my position is deleted. So... take your statement about "if a site..." and think about it. WUWT isn't on shaky ground, it's on fog.

Bob Lacatena at 13:43 PM on 1 June 2011Are you a genuine skeptic or a climate denier?
apiratelooksat50,Where do you look for further information?
I almost always find and read the original papers. When I don't understand the background science, I study that (but finding that is not controversial... I don't need to find a "balanced" site to explain how ice cores are analyzed to construct a proxy, or to understand how the satellites or radiosondes work, or the details behind molecular physics, and what the issues and complications and limitations are for any of them). I also usually read supporting, preceding, or conflicting papers. I will look at various sites to see what their "argument" is against a particular point of view, but I only use that to see what threads to pursue. Reading the actual studies... and understanding what they say... always leads to fair comprehension, not only in what I know and they know, but also what everyone doesn't know. By contrast, sites like WUWT and CA are nothing but vitriol and misleading misrepresentations. One can get absolutely nothing of value from those sites. -

Sphaerica 76, makes a comment about looking at various sources, but stay away from the likes of WUWT. While I have posted items at that site, I have yet to be "censored" or deleted. In contrast, some of sites advocating AGW have no problem deleting posts, such as those Sphaerica posts on. If a site has to delete items based on scientific analysis, and interpretation of said results, it shows it's true biased colors, and demonstates their position is on shaky ground.

Ken Lambert - The charts DB posted came from one of the links he provided, to Tamino's "5 Years" post. These are (to minimize arguments about data manipulation, and to remove high frequency noise) simple 5-year non-overlapping box averages, with <5 year periods being represented by the remaining data available (hence less smoothed). It's a nice illustration of what the long term trends are, with the short term noise averaged out. And it's an especially good antidote to some of the cherry-picking that goes on, for example, at WUWT, where they tend to select tiny periods to find short term down-slopes, and from that claim SLR is negative. -

#91 Michael Sweet says "James Hansen estimates the fast climate sensitivity as 3C based on paleoclimate data. " Over what time period do you think Hansen meant when he discusses "fast" climate sensitivity? -

The discussion with tallbloke should be taken to the censorship free zone on his blog. I can tell by his reply to me : "Yes, they must be mighty tired of nature refusing to co-operate with their co2 hypothesis." that it will be a most fruitful discussion. -

James Hansen estimates the fast climate sensitivity as 3C based on paleoclimate data. He further estimates a climate sensitivity plus albeido change from melting ice as 6C based on the paleoclimate data. The ranges of climate sensitivity range from 2 up to 10 degrees. The limits on the lower end are strong but the upper limits are much harder to define. 2C is a denier position without allowing the possibility of 7C which is just as likely. That 3C is only a fast feedback estimate, the slow feedbacks are all on the upside. Can the skeptics please start to link their opinions to some data. I see a lot of unsupported opinions about climate sensitivity ("the climate sensitivity was between 0.5 and 4.5C / doubling") without links. Without links to data these are just your opinion. -

DB #102 Could you explain the origin of the charts you posted in the 'green box' at #102. -

Albatross #105 Readers can judge for themselves when the my post being answered by Albatross at #105 has been deleted by Moderators without even a (snip). Hansen's latest synopsis explicitly draws conclusions about the reduction in warming imbalance from the OHC record for the period 2005-10 - 6 years. Yet I am criticised as a 'cherry picker' by drawing conclusions from the UCAR chart for the Jason 1 & 2 records over a 9 year period. This is then turned by Albatross into; "Not true-- and your accusation of cherry picking against Hansen is ridiculous and unfounded, or are you simply musing about scientific misconduct by one of the world's leading climate scientists?" I did not accuse Hansen of cherry picking. I said explicitly that if the likes of Albatross and DB want to label analysis and conclusions of short term records (in Hansen's case, 6 years) as 'cherry picking' then we are in the good company of Jim Hansen.
