curiousd, probably the most effective way you could direct your money for that purpose at the moment is towards solar cookers in India. One possible route for such donations is PRINCE. However, I found their website by a google search,and cannot guarantee their bona fides. Alternatively, contact any major charitable organization which assists with developmental aid, such as World Vision. Ask them what options they have in this regard. If you wish to do the research on available options, giving some guide to the reliability of the charity, and what portion of charitable donations go on administration costs, I very certain SkS would be happy to host the resulting article. -

I have an idea I would like to discuss, about how to fund renewable energy sources in a new way. Is there anyplace here I can appropriately discuss this, without being deleted? If not, where to go? Basically I want to contribute to a particular kind of charity that would help reduce CO2 emissions but no such charity exists and I would like to find out why. -

Tlitb1, all I can really offer to your points is that CSLDF organization is presently an all-volunteer outfit numbering only three part-time workers; without meaning to sound snide, if some of us in the wider world strongly believe some improvements can be made then it seems incumbent on us to volunteer either by making suggestions or offering labor. There's a contact page on CSLDF's site and that would probably be the best place to start. That, or contribute money to help CSLDF hire some staff support! -
curiousd at 18:04 PM on 18 July 2012Greenland ice mass loss after the 2010 summer
Regarding Glenn Tamblyn 14; "What to do?" Comments desired on the following: 1. U.S. citizens pay out about $1,000 per capita per year for various charities. 2. All over the place I see well meaning folks straining conditions in , say, New England, to make their own self sustaining home..say online solar plus geothermal. But as for me 3. Why is there no charity I can contribute to for constructing soneone else a renewable energy source where it would do the most good? I can envision some variant of Habitat for Humanity focussed on installing solar in Arizona or people banding together to sponsor a windmill in the Gobi desert. Starting small, this could become big time....hundreds of billions of dollars. Then people living in Chicago high rises could donate money for renewables that are impractical for Chicago high rises? Why is there no such charity? Why? -

doug_bostrom at 09:42 AM on 18 July, 2012I don't see a problem, other than the "Campaigns" description might do equally well in the About Us page. I probably should have included all of this in the original article. Sorry about that.
No need to apologise I had no problem finding my way to the CSLDF page via your link and read all I could. As I said found it be rather sparse. In fact you reminded me of another part of interest in CSLDF. When I first asked whether other litigants were being supported by CDSL, I quoted the key section in the campaigns page you quoted:Currently several climate scientists have litigation in the courts.
I asked since the association with CSLDF of those several litigants seemed passively worded to me on that page. You replied:Regarding people directly benefiting from CSLDF assistance, so far the roster includes Mann, Hayhoe, Dessler.
I would suggest a further detailing of these other ongoing cases would be an ideal addition to lend more information. Currently the "Press" page currently only has 9 old references which refer to Cuccinelli's pursuit of the inquiry into grant money used by Michael Mann. Back in September 2011 Scott Mandia is quoted in one of those press cuttings (thinkprogress) as saying:All funds that are in excess of those currently needed for Dr. Mann will be placed into this entity for future use defending other scientists.
If it is the case and the excess funds are now being used to support other scientists then, regarding suggestions for improvements or updates to the CSLDF site, I would suggest this fact should be made evident to help show some progress of the organisation since September last year. -
angusmac at 16:23 PM on 18 July 2012Simply Wrong: Jan-Erik Solheim on Hansen 1988
Dikran Marsupial @82 (or should I say Gavin). I have been aware of your qualifications since my post @76. My comment regarding the difference between an engineer and scientist should not be construed as personal. It was meant to illustrate the difference between scientists (who carry out research and derive physical laws) and engineers (who use these physical laws to build things). In other words, engineers are involved in the appliance of science. Regarding good or bad engineering, let's assume that the temperature chart is analogous to wind speed. Now, engineers design structures for the 95-percentile (1.64σ) value to prevent collapse under loading, e.g. 50-year wind loading. This loading is derived from the existing wind climate records. However, these records may not apply to the next 50 or 100 years. Consequently, engineers would need to design structures for the projected (mean + 1.64σ) values determined by climate models. However, actual values are skirting the projected (mean - 2σ) levels and, if this trend continued, engineers could safely. design for the projected mean alone, i.e., approximately actual (mean + 1.64σ) values. This would result in huge savings in construction materials (circa 60%). I suggest that designing to the lower actual (mean + 1.64σ) level would be good engineering practice. I, for one, cannot condone the wastage of scarce resources which would be incurred by designing to the higher projected (mean + 1.64σ) level but, until the models become more accurate, this is what engineers will be forced to do. Regarding your penultimate paragraph "hubris". I don't think that I was being hubristic (having lost contact with reality or being overconfidently arrogant) when l stated that the parameterisations (rules of thumb) should be reassessed. Some models cannot even agree on the sign of these rules of thumb, e.g. cloud feedback. I am glad to hear that modellers are constantly revisiting the physics and I look forward to the day when there is much closer agreement between the models - presumably due to fewer differences in the individual models' rules of thumb (parameterisations). -

#29, I was motivated to actually check the source of one of your fragmentary statements. This is what I found. Hansen, making a model-observation check in 2005:Curiously, the scenario that we described as most realistic is so far turning out to be almost dead on the money. Such close agreement is fortuitous. For example, the model used in 1988 had a sensitivity of 4.2°C for doubled CO2, but our best estimate for true climate sensitivity[2] is closer to 3°C for doubled CO2. There are various other uncertain factors that can make the warming larger or smaller[3]. But it is becoming clear that our prediction was in the right ballpark.
In 2005, the observed temperature was, as it had been doing for the preceding six years, following Scenario B closely (Figure 1 in Hansen's piece). In 2005, it was ever so slightly above the B scenario; 2004 a little below, and 2003 almost exactly on the same value. These observations did not require elucidation of errors, they were a comparison of observations to a specific model, and the observations at that time merited "almost dead on the money. Hansen also goes on to say that was lucky in this, as his sensitivity was too high and other factors weren't included. But the 2005 'dead on the money' quote, when placed into context is correct. Its context is 2005, not 2012, where the fortuitous circumstances that allowed Hansen to make the above statement no longer apply. -
angusmac at 15:27 PM on 18 July 2012Simply Wrong: Jan-Erik Solheim on Hansen 1988
scaddenp @79 and Dikran Marsupial @80 May I summarise your responses as GISS had a lack of time to re-run Model II and I respond as follows:- I have downloaded Model II and the EdGCM version.
- Mark Chandler and his team should be congratulated for providing an excellent user-friendly interface to Model II. Only experienced FORTRAN programmers will understand the original Model II source code.
- A typical simulation run from 1958 to 2020 takes approximately 3-4 hours on my laptop but, more importantly, the simulation works in the background and therefore you can work normally whilst the GCM is running.

Tom Curtis @26 & 27 Could you please elucidate regarding Hansen and the 2-sigma levels. I have already shown in SkS here @78 that the Hansen 1988 projections were statements of certainty. No mention of error bars in Hansen (2005) "almost dead on the money" or Schmidt (2011) "10% high". Your comments would be appreciated. Furthermore, my Figure 1 shows real-world temperatures are at the low end of the AR4 Commitment Scenario. Your comments would also be appreciated. -
angusmac at 14:59 PM on 18 July 2012Christy Exaggerates the Model-Data Discrepancy
Dikran Marsupial @24 & 25 When I said that the grey hides the 2-sigma trend in Figure 2 perhaps I should have been more explicit. The uniform grey shading implies a uniform probability of occurrence but what I should have stated is that a contour diagram similar to that below shows the probability distribution much better.
Source: AR4 Figure 6.10c (IPCC, 2007)
If Figure 2 had used percentile contours (as in the above diagram) then it would be evident that the 2-sigma values would be the lines at the extremities of the diagram and that most of the model runs would be near to the mean.

skywatcher at 13:41 PM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
Eric #30, to me, it crucially depends on the question. If the question is: "How does variability in 1955, 1965 and 1975 compare to variability in the 1981-2010 period?", then Hansen's Figure 3 is your friend, and is the correct use of standard deviation (1981-2010); I agree with Hansen's consistent use of 1951-1980 as a fixed baseline period from which to compare more recent changes. Alternatively, for: "How does variability in 2006-2011 compare to variability in the 1951-1980 period?", then Hansen's Figure 6 is your friend. Here, the 'base' variability is 1951-1980, and we see how recent years fare on that scale. Both are (slightly) different, and both perfectly valid, depending on the question. I suspect Figure 6 is land-only as they consider the 1951-1980 marine data not as good for baselining as the 1981-2010 period (from text bottom of p7). For the land areas, we can actually see the difference the sd's make by comparing Figure 3 and Figure 6. We may well agree quite a lot, but only, I think, if you'll agree (in contrast to your earlier statements), that there is excellent global-scale evidence for heatwaves to have increased both in frequency and in intensity. The evidence is pretty plain in Figures 1 and 5 of the Hansen paper. -
CRV9 at 13:10 PM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
@23.Paul D at 04:42 AM on 18 July, 2012 I don't know what do you mean but I think it works like this. Refrigirant takes heat/heat exchange, like water evaporation, from the inside of a fridge. And it carrys to out side in the back of the fridge then releases the heat/heat transfer, like water vapor becoming rain. Electrocity is used to run a pump to circulate the refrigirant and the electric pump gets hot when it is running. So if you leave the fridge door open on a hot summer day, cool air inside cancels out hot air in the back of the fridge. And heat from the electric motor pump would warm up your room, I think. I don't think it is quite same as "a gradual increase in energy in the climate system, from green house gases.", though. -

michael sweet at 12:18 PM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
Eric (skeptic), It is good that you have dropped your false standard of the 1950's being "cold". Your suggestion for moving the baseline is completely incorrect. Hansen is comparing temperature distributions from 1950 to the current distribution. Hanson has used a 1950-80 baseline for comparison ever since 1980. Why should he change to a period where the temperatures have gone up an additional .4C? The data I linked shows that in 1950 the temperature had already risen by about 0.5C from 1880. Your suggestion to continually raise the baseline artificially hides the increase in temperatures. Why would you use the hottest temperatures in the past 2,000 years as your baseline for measuring an increase??? I noticed a recent post at WUWT that used a baseline of 1980-2010 to hide the increase in temperatures in this way. Have you complained to them about their misuse of the baseline? Suggesting "the old climate normal of 1971-2000" is simply uninformed. This is only "normal" on skeptic sites who are trying to fool people who do not understand the data. Perhaps you should change your handle to Eric (credulous) since you believe anything you see on the "skeptic" sites without any supporting data. -
Eric (skeptic) at 12:17 PM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
skywatcher, you are right about the baseline not mattering when depicting plain old anomalies. But Hansen et al show anomalies in fig 3 using the 1981-2010 std deviations as units, not simply temperature anomalies. In fig 6 they used the 1951-80 standard deviations. I am really not sure which depiction if any shown is most valid. I would have depicted the broadest baseline and standard deviations from that. My dilemma may be resolved by fig 4 which shows my preferred distributions in the right hand column. When using standard deviations, the baseline period does matter. I think you and I may agree on weather more than you suspect. I was trying to point out that the reason there are more extremes is that AGW creates them from existing patterns. What would have otherwise been a heat wave becomes an extreme heat wave. There is no resolution yet on pattern changes from AGW. The flattening distribution is evidence in that direction but not conclusive. sauerj, I'm not sure about the article, but I claimed above that El Nino will shift the jet stream south and bring relief to the continental US (at first only some parts). The El Nino will also raise global temperatures next year if it continues, but may or may not raise US summer temperatures (really strong -> yes, not strong -> no). -
Bernard J. at 12:15 PM on 18 July 2012Patrick Michaels: Serial Deleter of Inconvenient Data
KR's point at #175 deserves repeating:Chip Knappenberger - Based on examining Michaels work, the words here: (figure adapted from Gillet et al., 2012: note the original figure included additional data not relevant to this discussion) should really be interpreted as: (figure modified to remove data that contradicts our talking points) Given the multiple examples listed in the OP, I really see no other valid interpretation. The message Michaels presents is completely contradictory to that presented by the researchers of the data that has been distorted. That's not a disagreement on the main message conveyed by the authors. It is a distortion.
There are many reasons for repeating it, but one that always rings a bell for me is that it goes a long way to explaining why deniers of the science are so preoccuppied with getting unfettered access to data... ...to wit, their interest isn't in the expensive and time-consuming career of doing original science, it's in finding ways to discredit the work of others, which makes all that inconvenient original work 'go away' in the public's perception. What the 're-analysts' want to do is to show that consensus scientists are 'wrong', by using the data of the scientists themselves. Doing so goes a long way to 'invalidating', in the mind of the public, the entire consensus of the real, professional scientists. It's poisoning the well, and it's cheaper, quicker, and has same desired end result as the more tedious alternative of going to the bother of generating new 'data'. Of course, it's not actually 'scientific', or even honest if it involves deliberately misrepresenting the data, but for any vested interests that are operating with the same paradigm previously used by Big Tobacco, that's beside the point. All they need is for FUD to stick to the consensus science. -

Hansen's Jan-2012 forecasts sure paned out, definitely for the US (sks article here)! Compare this to flawed contarian predictions (Easterbrook, McLean, Others)! One more for the scorebooks! Question: This article implies El Nino will shift jet stream south and relief drought. I thought El Nino also brought on higher temps (which may only anchor the hot, high pressures even more, strengthening the drought). If the current budding El Nino intensifies (link), which seems likely, I would think this will only make next year's summer (2013) even worse (ugh!). I'm probably over simplifying El Nino impacts and year-ahead forecasts. Comments for what's in store for 2013 summer??? -
skywatcher at 10:15 AM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
It doesn't make a lot of sense to use 1950-1980 mean when that encompasses the former dates and not the latter.
Eric, I'm sure you understand more about anomalies and baselines than certain fake skeptics that could be mentioned. It makes no numerical difference whether you use the 1951-1980 or 1971-2000 baseline, the change is just the same. And if you keep shifting the baseline towards the present, you'll contribute to an illusion of temperatures not appearing as abnormal as they really are - for the uninitiated, temperatures won't be so far above the 'zero' point in the graph. Is that what you want? And mentioning the weather is a poor go as well. Changes in weather patterns over the summer are exactly what gives us the approximately Gaussian distribution of temperatures! Weather patterns are throwing the punches - sometimes below average, often near average, sometimes above, occasionally extreme. Move the distribution right, and the extremes become new records, and the weather patterns that led to above average conditions now lead to new extremes. This means there's both more extremes and greater extremes. There's really no getting around this. Figure 4 in Hansen et al is very telling in that regard - the distribution has shifted right and also flattened somewhat. Had the distribution narrowed, there would be an argument to say there might not be so many extremes. But with more energy in the atmosphere, the distribution has, as would be expected, broadened as it moved to the right. Should the world continue to warm, and there is no reason on Earth to believe that it won't given the physics of the radiative forcing, the distribution will continue to move to the right and flatten. -

tlitb1 ...but I think for the time it has existed the CSLDF really should have had their remit laid out in a more clear and definitive way by now. Three part-timers; how about we cut 'em some slack? Anyway, let's look at the Campaigns page of CSLDF's site, which nicely describes what the organization is doing and leaves little doubt as to their objectives: Litigation: The Climate Science Defense Fund is taking an active interest in litigation. Currently several climate scientists have litigation in the courts. The Climate Science Defense Fund will play an active role in helping raise funds for their defense, serving as a resource in finding pro-bono representation, and providing support during difficult litigation proceedings. Education: The Climate Science Defense Fund will work to educate the scientific community about their rights and their responsibilities with regard to legal issues surrounding their work. Knowledge Bank: The Climate Science Defense Fund will serve as a clearinghouse for information related to legal actions taken against scientists. Our goal is to provide lawyers representing scientists with information about past cases and strategies. I don't see a problem, other than the "Campaigns" description might do equally well in the About Us page. I probably should have included all of this in the original article. Sorry about that. -

Chip Knappenberger @174, as shown by the quotes in the OP, you clearly also disagree about the germaine messages the authors intended to convey with their figures. In any dispute such as this, their opinion is the final authority. If Hansen and Urban think their graphs have been distorted, as they clearly do, the only honourable thing to do is to take down the offending graphs and replace them with exact copies of the original, noting the replacement and apologizing for the distortion while doing so. That is not an optional standard, IMO. Compliance or non-compliance with that standard marks the difference between an honest commentator and a propagandist. -

Tom Curtis at 08:05 AM on 18 July 2012Patrick Michaels: Serial Deleter of Inconvenient Data
Chip Knappenberger @171, your current argument seems to be that altering the figures is no greater an offence than simply cherry picking data (which you do not agree that Michaels has done). That position, however, is unsustainable. Allow me to illustrate. Creationists are well known for out of context quotations. One of the most famous examples come from Whitcomb and Morris, "The Genesis Flood" 1961, where they quote Ross and Rezak as saying:"Most visitors, especially those who stay on the roads, get the impression that the Belt strata are undisturbed and lie almost as flat today as they did when deposited in the sea which vanished so many million years ago."
They adduce this quote as evidence thatthe contact plane between the Lewis Overthrust and underlying strata are undisturbed, and that therefore no over-thrust occurred. What Ross and Rezak actually wrote, however was:"Most visitors, especially those who stay on the roads, get the impression that the Belt strata are undisturbed and lie almost as flat today as they did when deposited in the sea which vanished so many million years ago. Actually, they are folded, and in certain places, they are intensely so. From the points on and near the trails in the park, it is possible to observe places where the Belt series, as revealed in outcrops on ridges, cliffs, and canyon walls, are folded and crumpled almost as intricately as the soft younger strata in the mountains south of the park and in the Great Plains adjoining the park to the east."
By simply deleting an immediately related and obviously germaine sentence, Whitcomb and Morris turned a clear description of massive disturbance into an apparent description of no-disturbance. This process, out of context quotation, is an additional offence on top of the act of cherry picking. It amounts to both a lie and a slander - a lie because it presents a clear untruth about what Ross and Rezak said. A slander because in doing so it would have denigrated their reputation among people who knew about the Lewis Overthrust but did not know the full quotation. The examples of graphic distortion by Michaels given above are exactly analogous. In each case, the authors had a much larger message which they considered integral to the situation; which Michaels deleted without acknowledgement because he found that integral information inconvenient. So, in each case there is an additional offence to the cherry picking. It is the implicit lie about what the original authors wished to convey. http://holysmoke.org/icr4cult.htm -

Chip Knappenberger - I will simply point to an earlier post I made in this thread.Patrick Michaels and Chip Knappenberger are principals in New Hope Environmental Services, "an advocacy science consulting firm" that apparently contracts with various fossil fuel interests (Patrick Michaels - 40% of income from the fossil fuel industry)[ ] ...presenting edited graphs (and misquoting papers) IMO crosses the line between advocacy and, to be frank, deception. A harsh statement, but I feel well supported by the data, as presented in the OP here and on the links in various comments. Michaels and Knappenburger are living examples of the Nick Naylor character from Thank You For Smoking.

KR, As evidenced in this thread, I have laid out our justification and intent. You are free to disagree. But, this would have been the case whether or not we altered the original Figures or plotted our own. So that part of the argument--altering the original Figures (with acknowledgement)--is a distraction, rather than some sort of a gross offense as dana1981 seems to want to make it. -Chip -
EliRabett at 07:32 AM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
`cynicus, sadly no. While the Gaussian has flattened, as one would expect, the shift of the mode to higher temperatures means that the probability of cold spells is much less today than it was before 2000 AND there is the extra special hot tail on the distribution to warm you up. Also where you pick the climate mean has little to no effect on the result it just shifts the zero for everything. -

Chip Knappenberger - And likewise, you (or me, or Pat) have the opportunity to distort a data set by erasing relevant portions, thus misleading the readers of that piece. Yes, the Eos op-ed suggestion would make it a bit easier to find the original data. But it by no means excuses distorting the data in the first place, thus misleading those to whom that might be the only presentation seen. It does not excuse mendacious behavior. And I use that word quite deliberately, given the documentation in the opening post of just what kind of distorted impressions can be made by modifying the data and the results of others, making a false argumentum ad verecundiam by presenting such distortions as the work of reputable scientists. -

However now that I know about the existence of CSLDF I will be following its progress with interest. Thanks -

KR, If you (or me, or Pat) had the data available, you (or me, or Pat) could plot it up however desired along with any appropriate commentary. You (or me, or Pat) wouldn't have to alter the original figure in order to emphasize, simplify, clarify, or whatever, a particular point. Certainly, the authors of a paper are free to reach their own conclusions given the data, but so too are others. As the Eos op-ed was suggesting, having the data available to do so, would make doing so a lot easier (and, I might add, eliminate squabbling over alterations to a Figure). -Chip -

Chip Knappenberger - Publishing your results is a reasonable idea, although the cost issue simply will not go away - cost per GB may drop, but more and more data gets collected all the time, filling all of the space available. George Carlin pointed this out quite a while ago. Personally, I would argue that having the results and the methods published are sufficient (they have been so far, ever since the instigation of the scientific method in the 17th century) as other investigators can check those methods and their own data for consistency and replicable results. However, this really has nothing whatsoever to do with the fact that Michaels has repeatedly erased portions of illustrative graphs in a fashion that can only be characterized as deceptive (as in the opening post) - removing data that contradicts the arguments he is making. Even if all data, all results, all graphs are available somewhere, graphs with missing data, missing the point made by the original authors and hence distorting the message the authors drew from their work, is simply not a legitimate tactic. -

Nice post on the statistical nature of climate as related to extreme weather events. Figure 4 could be useful for tv meteorologists to help explain what global warming means for weather extremes in our future. For example, if 3-sigma corresponds to a "hundred year event" of some type (heat, drought, flood, etc.), then with the climate shift that event occurs 10 times as often, so former hundred year events become ten year events, and if we don't act aggressively to reduce GHG emissions soon, the shift will increase further and they'll become annual events. -

michael and doug, Hansen is comparing 1955, 1965 and 1975 with 2006-2011. It doesn't make a lot of sense to use 1950-1980 mean when that encompasses the former dates and not the latter. He should use 1950 to present for that graphic, or the old climate normal of 1971-2000. -

Is there a psychological reason why heat waves, drought etc attracts more interest when it comes to global warming than record rainfall and wind. What we see is a gradual increase in energy in the climate system, from green house gases. There is no reason why that energy should manifest itself differently. Think of a fridge, it gets cold because of an input of energy, whilst the surrounding air gets warmer. If we applied the same logic that many expect of climate change, then the fridge wouldn't get cold at all, but would get slightly warmer, as it takes energy from the electricity supply. Maybe I have created a new analogy here??! There are no rules saying that everything will get hotter, evenly. -

Will James Hansen soon release the final draft of "Public perceptions of climate change and the new climate dice", because I heard that the current version of the paper released in November 2011 is a rough draft? -

Further to Michael Sweet's remarks, the graphic here helps to illustrate the situation w/regard to the '50s and Hansen's base comparison figures. Regarding garethman's questions: Since 2007, a series of major reports has emphasised the fast growing risk of flooding to the UK as the climate warms. On Wednesday, the government's official advisers, the Committee on Climate Change, warned that number of homes at risk of flooding is set to quadruple in the next 20 years and that flood defence spending must increase. The government's own report on climate change risk in January said flooding was the UK's greatest climate threat, with annual damages set to rise to billions of pounds a year. More The trouble is, the UK government is heading in the wrong direction: Caroline Spelman's deep cuts to flood defences begin to look foolish

@Gareth #1 Given that they're predicting that the jet stream over the UK will shortly move north after giving us such an extremely wet and miserable early summer, I'll be interested to see whether it coincides with an end to the US heatwaves. I tend to think of the jet stream like a rope with waves travelling along it, so that if one part rises another falls. That's not very scientific but there must be a logical connection between different parts of the jetstream. Oh, and I'm sure everyone will be pleased to know that in-denial weather forecaster, Piers Corbyn, is announcing in his usual alarmist style that the current weather is due to carry on -- thanks to the sun. Extraordinary. -

dana1981, I stopped by to point you to a recent Eos op-ed about making the data available that are used to construct the figures in AGU publications. The point being that others could more easily “use the results” of the published papers. This would alleviate the issue of which data others wanted to use (or graph) and thus largely eliminate your concerns about “deleting data” from graphics as they were originally published. But, along the way, I came upon this article. And I thought I should point out a correction. The Davis et al. (2003) is not referencing a paper published in Climate Research, but from Environmental Health Perspectives (as you should very well know since you provided a link to it in your article you linked to in this piece). Hopefully you can clarify this for your readers. Thanks, -ChipModerator Response:[DB] For those unacquainted with Eos, Eos is the AGU member newspaper. It is not a journal and does not publish original research results. FYI.
Fixed link.

Cliff Mass, University of Washington Meteorologist and Pacific Northwest weather blogger, disputes the Texas heatwave 20 times more likely estimate. http://cliffmass.blogspot.com/2012/07/texas-tall-tales-and-global-warming.html His blog entry has now been reposted at WUWT and is providing lots of fodder for the skeptic crowd. -
michael sweet at 03:11 AM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
Eric, Please provide a reference for your wild claim that 1950-1980 was unusually cool. That time period was much hotter than 1900-1930 see this graph. You need to pick claims that are not easily shown to be false. The deniers now claim that warm periods in the past were cold. That means it will never be warm since 1,000,000,000 years ago it was warmer than it is today. -
Doug Bostrom at 02:34 AM on 18 July 2012What is the Climate Science Legal Defense Fund?
I should add, a cease and desist letter is not litigation but it points in that direction as a possible consequence; not much point in communicating "please stop harassing my client or nothing bad will happen to you." -
cynicus at 01:44 AM on 18 July 2012An American Heatwave: The United States Glimpses its Hot Future
@16 Eli, it's also less worse because the same paper shows that the distribution at the cold end hasn't changed as much as the warm end. So luckily there will still be some cold spells to be used as "look squirrel!". Many blogs, including yours, wouldn't be even half as much fun without. -
Doug Bostrom at 01:21 AM on 18 July 2012What is the Climate Science Legal Defense Fund?
Actually I understand titlib1's concerns. If an organization were to recklessly launch a litigation effort then large amounts of money could be expended pointlessly. That's not the case here, however; there's no sign of aggression on CSLDF's part. They've said they have no plans to launch any litigation. So why would CSLDF not rule out litigation on their own part? That's not hard to figure out. Cease and desist letters are one possibility, obviously. Leaving aside what exactly constitutes a death threat, if somebody sends to a scientist a letter connecting the scientist's family, uninvited visits to the scientist's home and some implication of violence then ensuing and makes the mistake of including identifying information in that communication, they should expect to hear from either the authorities or somebody representing that scientist and telling the offending party to stop. Other milder forms of harassment might also benefit from a cease and desist letter. It's not hard to imagine some other scenarios where a little bit of legal help beyond pure defense against litigation might be appreciated. There are other less drastic forms of proactive legal work short of cases making it to court. -

Albatross at 00:38 AM on 18 July 2012What is the Climate Science Legal Defense Fund?
This has become a very long thread, so I hope that the moderator's will permit me to repost two questions I asked earlier of people posting here to defend Mr. McIntyre and others like him who harass scientists. 1) Can they "…bring themselves to acknowledge that it is a travesty that a legal defence fund is required (out of necessity) to protect the rights, integrity and academic freedoms of certain climate scientists following repeated harassment, threats, bullying and intimidation from certain "skeptics" and certain individuals and groups who deny the theory of AGW." 2) "Do you support the scientists or those who bully, intimidate, threaten and harass them?" tlitb1 has very clearly demonstrated that he/she does not share our concerns and stated that his/her allegiance lies with the likes of Mr. McIntyre. So what about Carrick, Lucia, dubious and dougz?
