Doug Bostrom at 17:18 PM on 18 October 2012The Future We All Want
Solar domestic hot water is the poster child example of how feckless we are in our energy habits in the United States. Point your browser to the following Google Maps link and cruise around. The location is Sun City, Arizona. Take a look at the rooftops. What's missing? What's under the roof of every single one of those dwellings, consuming about 20% of the household energy input? Meanwhile, Arizona's electrical generation capacity is overwhelmingly powered by fossil fuel including substantial coal generating capacity. Water heaters not using electricity as an intermediary between flaming coal and natural gas are just burning gas directly. When we look at Sun City AZ we're looking at a community of recalcitrant cavemen, just one town of thousands, a few hundred households of hundreds of thousands more. This is basically insane. Solar domestic hot water is deadly dull old-school technology, Joe-the-Plumber state of the art. Dollars and watt-hour equivalents are sleeting down from the sky in positively destructive quantities in Arizona and much of the rest of the United States yet we're so slothful and lazy we won't lay our hands out to grasp any of the free stuff. Crazy. Do we want to be losers? Do we deserve to be losers? Sometimes it seems we convey that impression. -

Hi Doug! You raised a very interesting point. Thank you! Yes, solar water heating is by far the best option since this system will reduce the emissions of greenhouse gases. Coal is the main source of energy in Australia as far as I know which is a problem of major concern. Anyhow modern electric tankless water heaters are very efficient in terms of energy consumption and their units do not emit greenhouse gases. -

Very interesting to see how all the factors interact. [pedantry]The large swells caused the breakup of large (>1 km) multi-year ice flows up to 5 meters thick, into much smaller flows (100-150 meters).

Yubedude, While you've done a great job of illustrating the methods of the denialist mob, I don't think much can be done about it. If you're hoping scientists will or can modify their language to stop people from doing such things, I think it's asking the impossible. About all that can be done is to educate people who are interested in truth and hope enough take interest to spread the word. Truth, especially in complex matters with political implications, is always at a disadvantage. Thanks to Skeptical Science for providing us with so much of what is needed to do the job. -
YubeDude at 12:59 PM on 18 October 2012What Role Did the Arctic Storm Play in the Record Sea Ice Minimum?
What Role Did the Arctic Storm Play in the Record Sea Ice Minimum? Here are a few questions I can’t help but ask that come from the heading: Comments from Arctic Experts NSIDC Director Mark Serreze is quoted as saying, "Apart from one big storm in early August, weather patterns this year were unremarkable. The ice is so thin and weak now, it doesn't matter how the winds blow." How does he qualify “unremarkable” and can he empirically prove that “it doesn’t matter how the wind blows”? You quote SIDC scientist Walt Meier saying, "... Arctic sea ice cover is changing....large areas are now prone to melting out in summer." Isn’t it true that Arctic sea ice has always been a seasonal phenomenon with highs in the winter and lows in the summer? Is it not the nature of ice to go through cycles of melt/freeze, a kind of “changing” as temps rise and fall? Claire Parkinson at NASA Goddard Space Flight Center said, "The storm definitely seems to have played a role in this year's unusually large retreat of the ice.” She appears to disagree, and if there is disagreement between the Arctic Experts… Do you see what I did there? Snip, clip, and disregard the bulk of your offering that details actual science in favor of misquoting Experts who I’ve extracted from context and then asking questions that are plausible yet remain fallacious; questions that give the appearance of being reasonable. The battle is over more than just the facts, science and understanding. After all, I am not trying to convince you or those who do the research and publish the papers; you are all in the minority. I’m going after the hardware store owner who won't check the quote to see if I left something out, the wheat farmer who is great with his hands but not with science text books, and that guy on the subway who reads the WSJ and is worried that his portfolio might take a hit anytime someone suggest AGW is real. Your article is excellent by the way and I appreciate your efforts and synopsis of our current status. -
Doug Hutcheson at 11:34 AM on 18 October 2012The Future We All Want
Interesting that in point 5 they say "Gas water heaters should be avoided as they emit greenhouse gasses". In Queensland, govt. regulations now require gas water heaters: we cannot replace our existing electric system with another electric one. I wonder whether the GHG emissions of a gas water heater (storage type, not on-demand) would be greater than the equivalent electric heater, taking into account generation costs and line losses etc. A solar hot water system with heat-pump backup might be the low emission choice, but not cheap. -

If I might repost this comment I left on the Met office blog? While responding to one of the "climate has always varied and natural variability swamps the CO2 signal so AGW is insignificant" types, I came up with an analogy I haven't seen before which I think might be worth passing on for others to use when trying to communicate the subtleties of the sophistry being used to fool a too credulous public. I already know the analogy isn't exact, but it does have power to communicate an idea... ______________________________________________ “But the climate is always changing” Of course it is! Within limits. So what? Climate changes, and has changed, due to natural forcings and cyclic variabilities. That clearly demonstrates that it reacts to forcings. Sticking a load of buried then re-oxidised carbon back up there is imposing a long lasting forcing on the planet that steadily forces the climate to change. The physics shows that the C02 forcing is much larger than the orbital Milankovitch forcings that send Earth into and out of ice ages over millennia. I see several others have come on here and pulled the old “natural variability swamps any CO2 signal”. Did you all miss the analogy above between waves on a beach and the tide coming in? How hard was that to understand? Another analogy I just made up would be a fat person eating, in aggregate, just 200 calories a day more than their body burns averaged over 20 years. Over 20 years plus they are going to get to be a morbidly obese 600 pounds! How would you all regard the intelligence of someone watching them who said that the person sometimes binged on 5000 calories a day for weeks, then went on a crash diet for weeks and their weight varied by 50 pounds cyclically but that the steady average one ounce a day weight gain from those unburnt 200 calories is totally “swamped” by their natural cyclic variability, so therefore is unimportant? I don’t think that is very smart. Do all you “natural variability swamps the CO2 signal” types agree now? Small cumulative dietary forcings add up to one obscenely fat individual over time. Climate forcings in the SAME direction mean steadily accumulating heat. Binges and diets give a wide CYCLIC variability of weight month to month. Just as natural oscillating climate variations give a wide variety of temperatures over decadal periods. So what? A fatty in denial of reality could easily pick and choose start and finish points to draw trend lines on the graph of their weight to fool themselves into thinking they were losing weight or stable – that they were doing fine – but they would be deluded… -

Further to my above comment, ironically the article that Curry posts (apparently journal articles are not up to snuff for her to use as support for her claims, instead she is relying on a he-said-she-said reported in the media) to try justify her claim of the "pause", includes a statement that calls out the 1997-1998 El Nino start date (the same one used by Rose) as a cherry pick: "Researchers have long argued that using 1998 as a starting point was, then, unfair. "Climate scientists were right that it was a cherry-picked observation, starting with an El Niño and ending with a La Niña," said Robert Kaufmann, a geographer at Boston University who recently studied the hiatus period.." Ultimately what we have is a global radiation imbalance of about 0.6 Wm-2, and so long as there is an imbalance, the climate system will continue to accumulate energy and warm, not always at the same pace, but physics dictates that on time-scales of 20-30 years it must warm. It is not clear to me that Lean acknowledged the "pause" either. In the quote provided by Curry, Lean is instead speaking to the role of the sun in modulating global temperatures. The author claims that Lean attributes the "hiatus" to the sun, but nowhere does Lean explicitly state that. Also, there is a problem with that reasoning, because there was a solar maximum in 2002-2003, so if the sun were the culprit, one could only attribute a slowdown in temperatures after 2003, not since the 97-98 El Nino. Importantly, the warmest year on record, 2010, was observed when the sun was experiencing an unusually prolonged solar minimum. As per usual the "skeptics" (including Curry it seems) want to everyone to focus on the noise and ignore the long-term and much more important big picture. -

Dana @37 and 38, This latest sad saga with Curry would be quite entertaining if this were not such a serious subject. If I were you I really would not be too concerned what someone who is wowed by Salby's misguided ideas or believes David Rose's misinformation articles to be "thought provoking". Perhaps I was too unclear earlier as to what is likely going on here. Curry and Rose have a symbiotic relationship. Rose promotes her and feeds her narcissism, she gives him the sound bites and credibility that he can used to mislead and misinform. I'm beginning to think Curry's indignance about being misrepresented by Rose is a ruse. Additionally, as Dikran Marsupial has accurately noted "Judith Curry demonstrates a fundamental lack of understanding about statistical hypothesis testing". That much is very evident when reading her posts. As for Curry trying to weave Trenberth's, Solomon's and Hansen's comments into her narrative. That is disingenuous on her part, because none of them assumes that the increase in global temperatures will be monotonic, and none of them assumes that periodic slow-downs or plateaus suggest that we are not heading for much discomfort and pain in the coming decades if we continue to increase greenhouse gas levels. What is more, using the Solomon quote is inappropriate because Solomon is talking about a shorter and different period than the period cherry-picked by Rose. Solomon was talking about the role of stratospheric water vapor on modulating global temperatures on a decadal scale, specifically their proposed role of cooling between 2000 and 2009, not 1997-2012. And as The Escalator shows one can easily find short-windows with cooling or no warming because of noise in the climate system. Finally, to my knowledge Hansen has not stated that there has been a significant slowdown. And in that quote Curry provides he does not do so either. In fact, Hansen et al. (2010) challenged Solomon's claim of a slowdown: "On the contrary, we conclude that there has been no reduction in the global warming trend of 0.15 C-0.20 c per decade that began in the late 1970s" If anyone doubts that Hansen is concerned they really should watch this incredible talk that Hansen gave at Ted recently. Curry is playing rhetorical games and misrepresenting her peers' positions by not providing the full context of their positions. That she is doing so is shameful and unprofessional. -
Falkenherz at 02:23 AM on 18 October 2012Climate sensitivity is low
Daniel, I do question about reality, and if reality is reality, I am confident that my questions will be answered. scaddenp, Hansen and Sato 2011 are a very difficult to read for me. If I understand their chapter 5 on the Holocene correctly, they use climate forcings calculated from GHG and sea level changes (=ice sheet approximisations) and apply climate sensitivity "consensus" values and thusly produce temperature curves which match the ice core data. Seeing that there is yet another article which again specializes within more details with regards to my questions on the ice core data, I will move on to the discussion of Shakun e.a., link provided by Daniel#295. -

Eric @43 - I'm curious, what does Tisdale propose caused the "charging of Pacific ocean heat in the 80's and 90's"? My problem with Tisdale's argument is that it kind of ignores basic physics. He made a comment the other day that it's misleading to look at global data as measurements of global warming because that leads to the assumption that greenhouse gases are responsible for some warming. I really can't take him seriously after that. -

The point about Rose is that his errors would seem to be deliberate. It may be that he has been unduly influenced by Monckton, who makes a habit of such behaviour. If they are deliberate errors and seeing as they have the result of hindering action to combat climate change, we can deduce that his intention is to harm his country. I think that there is a word for such behaviour, but I forget what it is. I know it begins with a 'tr' and ends in 'eason' but the rest escapes me. -

Lionel at #44. I remember wincing when I hear Phil Jones say that. My immediate response was to wonder why he didn't say something to the effect of:"There is a 94% chance that the observed planetary trajectory toward warming is not due to random fluctuation: that it is in fact reflecting genuine global warming. With another year's worth of data to discern long-term signal from short-term noise that figure will increase to greater a than 95% chance that the planet is warming."

Rob, yes, it's more than just "some". I agree with Tisdale that ENSO is not a "cycle" per se, but disagreed that it can cause secular warming before reading his book. When I finish reading it I will try to answer your question. The part that seemed worth mentioning is that ocean heat storage and release is a highly episodic process. IMO AGW simply adds to the storage episode which then adds to the release episode. Storage can span multiple La Ninas, neutrals and even weak El Ninos. -

Eric (skeptic)- "It is accepted science that some AGW is stored in the ocean" Some? 93% since the 1960's isn't what I would characterize as some. As for Tisdale, he has some rather unusual ideas about ocean processes. Given that ENSO has probably been around for millions of years, can you summarize how his hypothesis is supposed to work? -

John Brookes @41 This is the exchange between Phil Jones and Roger Harrabin of the BBC which you have in mind:B - Do you agree that from 1995 to the present there has been no statistically-significant global warming Yes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level. The positive trend is quite close to the significance level. Achieving statistical significance in scientific terms is much more likely for longer periods, and much less likely for shorter periods.
Found here: Q&A: Professor Phil Jones . The fake skeptics (and I recognise Hank_'s handle and MO from posts at DesmogBlog) never mention that 95% significance level or its significance. If the plane they were about to board had a just less than 95% significant probability of crashing would they continue? -

I've been reading Tisdale's ebook which blames recent warming on ENSO. While I disagree with his conclusion and some of his premises (e.g. his claim that back radiation does not really warm the ocean), his description of charging and release of heat is pretty good. Essentially there was a charging of Pacific ocean heat in the 80's and 90's interrupted by El Chichon and Pinatubo that was released in the 1997/98 El Nino. From trough to peak that raised world temperatures by 1C, with a lasting rise of about 0.3C using UAH satellite measurements which measure up in the troposphere and thus show larger swings. That late 1997 peak is an overshoot. It is accepted science that some AGW is stored in the ocean. I think it is also reasonable to assume that ocean heat is released unevenly and can result in large upward swings along with lulls in atmospheric warming especially when measured by satellite which highlights the swings. -

Cornelius don't forget that UKIPs energy policy is primarily based on the idea that AGW doesn't exist or is minimal. Secondly Monckton is a member of UKIP and is or was their science advisor. So any logic in policy is based on the idea that low carbon energy is not needed. -

The first thing I noted when I tried to produce the articles graph was that while they spoke of "since the start of 1997", the graph started late in 1997. I presume this was to avoid a cold start to the graph, but there may have been other reasons (I just can't think of any though). A couple of years ago, someone forced Phil Jones to concede that there had been no significant warming since 1995, and the "skeptics" made a song and dance about it. I suggest that from now on we just insist that any "no warming since" statement must start in 1995. A fake skeptic is anyone who thinks Christopher Monckton is a member of the house of lords. -

A "fake skeptic" is a person who is skeptical about anything they dont like but laps up anything they like without switching on any critical faculty at all. This is frankly normal human behavior but a decent science education should give a person the tools to avoid it (esp the scientific method). A true skeptic critically examines all evidence (eg most working scientists). -

hank @36 - yes, I read Curry's post and was impressed that she criticized me as 'needing to raise the level of my game' while herself managing to ignore nearly all of the points that I made in my post. She focuses entirely on the one point in Rose's article that's almost technically correct - that global surface temperatures have been pretty flat over the past 15 years, ignoring the fact that he wrongly equates this with "global warming" - manages to miss the point that I already acknowledged that the warming of surface temperatures has slowed (and discussed why that happened), ignores the fact that global warming has continued as measured by global heat content, etc. etc. I'll put it kindly and say I was not impressed by Curry's response. -

These are convenient because the AMO in particular goes for multiple decades so even 30 years of increase can still be attributed to them. I'm intrigued by this; surely for any kind of oscillation to increase (say) global surface temperatures, then some other part of the planetary system must be cooling: if it isn't then its not an oscillation of heat at all. Does Curry have a candidate for this - or is it just waffle ? -

"we don't know the physical trigger process" How on earth do you deduce that?

Untangling this web quantitatively has been a slow process. Have a look at fig 6 of Hansen and Sato 2011 and tell me again that this isnt understood. -

Albatross: "Do they really think that people are so obtuse as to not keep track of such things?" Yes, they do. They depend on it. If people had the time, energy, training, and/or means to fact check, opinion-makers like Rose and Watts would be doing something honest for a living. In general, it's not deliberate stupidity. It's just a lot of work to get to a point where one can be confident about the basis of one's beliefs. I'd argue that in the eyes of most people, Rose appears at least as trustworthy as government-supported scientists -- not very trustworthy. How many people have read Rose and followed up by going to the Met Office blog? How many then went to verify from a third party. And so on . . . ? -

Great article, thanks! I have one question, looking at the figure 2 I see that the heat content of the atmosphere is 2.3%, based on a period of 10 years.

Um, "consensus" is that climate sensitivity is bewteen 1.9 (or so) and 4.2 (or so) with a central estimate of 3.0 being strongest. That you characterize that as "high" speaks volumes." if we don't know the physical trigger process"

JoeRG @55 - MarkR @58 is correct. Fair point that it may be overreaching to say that the rise in global heat content has accelerated, and it's not something we said in the paper itself. P.T. @57 - NCDC and GISS use the same raw data, but each applies their own adjustments to that data in order to estimate the average global temperature. The only thing their datasets have in common is the use of the same raw data from the GHCN. See here. -
dana1981 at 03:34 AM on 17 October 2012Misleading Daily Mail Article Pre-Bunked by Nuccitelli et al. (2012)
I have zero sympathy for Curry here. Rose is notorious for distorting climate science in every article he writes on the issue, and as others have noted, Curry herself claims to have been misrepresented by Rose in the past. Maybe she should learn from these experiences and stop granting him interviews, because he clearly views her as an easy target to support his climate denial. -
Falkenherz at 03:11 AM on 17 October 2012Climate sensitivity is low
Philippe, I ignored Milankovitch cycles (MC) because they are uncontested and I assumed they would have a certain known impact on global temperature, thereby initiating ice ages. Reading through the links you provided, this assumtion is wrong. If I understood correctly, nobody really seems to know the physics of the trigger for global temperature changes, only that MC must be a trigger, and it is assumed that glacial changes on the landmass-rich northern hemisphere play a key role. In other words, there is no initial rise of global temperature as the initial trigger, but rather some severe local imbalances. This just in short, because there is that other article specifically on MC. My research here is about climate sensitiviy, and specifically why consenus seems to be that it is high. So right now I am puzzled why people assume a high climate sensitivity if we don't know the physical trigger process. After all, if I understood correctly, it seems like local insolation can peak at 600 W/m2, which would probably be a very strong trigger with only a low sensitivity required. I am unsure where to continue discussion. Maybe I best move on to the MC article. (I start feeling like a hyperlink nomad and comment-parasite. Do you guys maybe have a forum?) CBDunkerson, thanks for confirming no real strong TSI changes connected to the ice age cycles.
