Harry... Again, you're getting some stuff wrong. 1) There is NO absolute here. Nothing in science is absolute. Given a competing theory that would explain all the current empirical evidence every one of us here would change their opinion. 2) We continually entertain other possibilities. The problem is, every other explanation is not consistent with the data or even between ideas. 3) No. We believe that science clearly understands the problem and if we don't start applying solutions (that cost, yes, billions of dollars) we are going to have a much much bigger problem on our hands, and one that is likely not to be solvable. 4) No again. The frequency and severity maybe. That's different. 5) Have you ever tried posting as a person who believes AGW over at WUWT or JoNova? This is a pony ride you get here. -

apiratelooksat50 @50, sure apirate, all those American climate scientists produced studies that show global warming is dangerous because it would ingratiate them with the Bush administration. The fact is that funding from governments in western democracies is tied to quality of research; while funding from commercial interests is tied to furthering those commercial interests. -

scaddenp, 5/11/11, 13:50 PM [sic] CO2 residence time IPCC's First Assessment Report (FAR) has an introductory part titled Policymakers Summary. The Second (SAR), Third (TAR) and Fourth (AR4) have an introductory part titled Summary for Policymakers. IPCC explicitly addresses no one else in its Reports. The Policymakers associated with the IPCC would include US Democrats, formerly including Al Gore, and other Western politicians on the left. What they are supposed to do is heap honors on IPCC and its climatologists, turn a blind eye to scientific challenges to IPCC's model, fund evermore super supercomputers and studies with them, and redistribute world GDP among all nations by voluntarily crushing energy use in proportion to national GDP. -

JMurphy @ 58 From the Urban Dictionary (these are not my words) To be defined as a global warmist, a person must have all of the following traits: 1) An absolute belief that humans are primarily or even completely responsible for causing a mass climate change which will raise the average temperature of the planet. 2) Will not entertain the idea that it is possible that natural phenomena may cause climate change, regardless of any evidence. 3) Believes it is a good thing to throw billions upon billions of dollars at an idea that may or may not work to stop climate change, "just in case." 4) Believes that natural disasters such as hurricanes and earthquakes are an indirect result of humankind's actions to cause climate change. 5) Shouts down, puts down, and insults anyone whose beliefs run contrary to their own, rather than having intelligent discourse. A zealot for their cause. And while we are at it: Climate change denial is a term used to describe organized attempts to downplay, deny or dismiss the scientific consensus on the extent of global warming, its significance, and its connection to human behavior, especially for commercial or ideological reasons. -

drrocket at 07:10 AM on 12 May 2011CO2 has a short residence time
Eric (skeptic), 11:22 AM, 5/11/11, CO2 has a short residence time 1. Take a look at the air-sea flux in IPCC's carbon cycle for the 1990s here. AR4, Figure 7.3, p. 515. The natural fluxes in black, left to right, positive into the ocean, are 0.2-119.6+120-70.6+70 = 0. The anthropogenic fluxes in red are 2.6-1.6+22.2-20-6.4=-3.2 GtC/yr. In other words, 100% of nCO2 emissions are absorbed each year, but only 69.2% of ACO2 is absorbed per year. If the nCO2 and ACO2 uptake has the same mix as the emissions, then the absorption for 13CO2, x13, and correspondingly x12 must be equal to 1 for nCO2, and equal to 0.692 for ACO2, where 0 ≤ x_i ≤ 1. But how could x13 or x12 be aware of the origin of the species? The ratio of 13CO2 to the total CO2 is the variable R, and for the two species, R_n = 1.11123% (R_PDB) and R_A = 1.08101 ((1 + delta_13C)R_PDB = (1-0.0272)R_PDB). If we aren't particular about the mix of each species, then R_n*x13+(1 - R_n)*x12 = 1 and R_A*x13 + (1 - R_A)*x12 = 0.692. The solution, x13 = 1007.7 and x12 = -10.3, is not possible. 2. IPCC can't be pinned down on its well-mixed conjecture because it never quantifies what well-mixed means, (and because it has no mechanism to respond to challenges). IPCC ought to report the mixing as the variability in standard deviations divided by the average, or something equivalent, and then compare the ratio to a standard or requirement before qualifying it. IPCC admits that gradients exist in atmospheric CO2, detectable EW and an order of magnitude greater NS, which seems to be an admission that the gas is not well-mixed. IPCC shows that the ocean outgasses CO2 dominantly in the Eastern Equatorial Pacific, and absorbs a major portion in the polar regions, which are the headwaters of the thermohaline circulation. IPCC shows these effects in its Takahashi diagram. AR4, Figure 7.8, p. 523. However, the fluxes in the Takahashi diagram add to about an order of magnitude too small compared to IPCC's total fluxes in Figure 7.3. Deep, cold water saturated with CO2 is drawn to the surface by the Ekman suction on the Equator, where it is warmed to tropical temperatures to outgas CO2. The surface water then follows mean surface circulation patterns, arriving at the poles about a year later to feed the THC at about 0ºC. All along the year-long route, surface water cools, on average absorbing CO2. This creates a background flux of CO2 in the atmosphere that should be detectable without IPCC's calibrations. IPCC gives no indication in any of its Assessment Reports that its models account for these ocean and atmospheric circulations. NASA published a July 2008 image from AIRS of mid-tropospheric (8 km) CO2 here. The AIRS chart from July 2003 here showed much weaker patterns. NASA's 2003 caption includes this under-stated observation: This global map of mid-troposphere carbon dioxide shows that despite the high degree of mixing that occurs with carbon dioxide, the regional patterns of atmospheric sources and sinks are still apparent in mid-troposphere carbon dioxide concentrations. Climate modelers are currently using AIRS data to study the global distribution and transport of carbon dioxide. Note that atmospheric CO2 in 2003 had a high degree of mixing, no longer well-mixed. Still apparent indeed. CO2 patterns at the surface must be much more pronounced than the extreme lumpiness of CO2 evident at 8 kilometers. The atmosphere acts as a filter to reduce both resolution and evidence of surface patterning. It is not well-mixed above 8 km; it is even less well-mixed below. Whatever IPCC means by well-mixed, the satellite measurements puncture the conjecture. 3. The CO2 concentration rise is surely natural. As the Vostok record shows, it is in sync with temperature, but always lagging. The increase is a local effect at MLO, and IPCC's calibration to make other measuring stations agree with MLO is unwarranted. Furthermore, an intense pattern of CO2 rising from the Eastern Equatorial Pacific splits poleward, enters the Hadley Cells, then the Westerlies, with half descending across MLO as it cools. This puts MLO in a plume of outgassing, a major source amounting to about 60% of the estimated 90 GtC/yr from the ocean. The bulge at MLO is not 30-40% of 8 GtC/yr, but about 3-4% of 90. If that plume were stationary, then the rise seen at MLO might be just due to sea surface temperature. However, the plume might be wandering, a slow, climatic effect moving its ridgeline closer to MLO in modern times. This is speculation, but necessary on the heels of the failure of the IPCC model. An analysis of MLO data closer to raw data, along with wind vector, might shed light on why MLO CO2 concentration has been rising for the last half century. 4. Nothing can be established using thermodynamic equilibrium because it doesn't exist on Earth. It is precisely IPCC's reliance on that fiction that leads to a severe debunking. 5. I don't find any use for a net effect of the ocean. It always uptakes CO2 at 0ºC and at today's partial pressure before the water descends to the bottom. It outgasses CO2 from water 500 to 1000 years old, effectively at the concentration then, but released at the tropical temperature now. -

50, apiratelooksat50, Don't use the term "warmists." As far as funding... the difference would lie in whether the funding was supplied to actually do research and find the correct answer, whatever it may be, or if it was supplied to find a specific answer (along with any twisted, convoluted method to support that answer), no matter where the truth lies. -

David Horton at 06:40 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
MIne was a rhetorical "puzzle". Needs to be some better measure. "100% of climate scientists not paid by big oil", "100% of climate scientists without libertarian ideological beliefs" "100% of scientists who have done research into climatology" and so on. The "97%" figure always suggests that there is a serious minority, some brave, Galileo-like souls struggling against the crushing weight of enforced consensus, of actual climate scientists who disagree with the reality that increasing ghgs are causing rising temperatures and that humans are responsible for increasing ghgs. Instead it seems to be just Lindzen and Christy deliberately maintaining an illusion that there is still some serious scientific debate on these fundamental matters. I just have a feeling that they, and many other deniers, and the Koch brothers, would be quite happy with this graphic being reproduced for the next 20 years. -
apiratelooksat50 at 06:37 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
Danno @ #3 You are stating that the source of funding for research influences the scientist's results. "the 1% is a handful of scientists funded by the fossil fuel industry?" I see this a lot when referring to skeptics. Not so much when referring to warmists. But, if you are right, then all sources of all funding to all scientists must be considered. And, you are thus implying that all scientific research is inherently flawed based on funding. -

Harry Seaward, rather than copying the views of a certain individual who maintains a little list of what he considers to be 'peer-reviewed' papers against AGW Alarm (whatever that means), why not actually search out the facts for yourself. Here is the Doran listing. Here is a world-wide survey. Here you can count up to fifty, to find all the scientists who go against the consensus. (Actually, the number doesn't reach fifty but some will prefer any little number to the thousands who agree with the consensus. Why is that, I wonder ?) Also, Harry Seaward can you confirm your backing for the 100 scientists (i.e. twice as many as those mentioned in my last link here) I mentioned in previous post. -
Rob Honeycutt at 05:55 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
Again, Harry... Where is the information showing that the studies are in error? Where is the study showing that a larger number of climate scientists doubt AGW? You're not putting forth any reasonable refutations of these two papers. RE: Anderegg... 1. Has no bearing on the results. 2. Has no bearing on the results. 3. Has no bearing on the results. 4. Has no bearing on the results. 5. Also, has no bearing on the results. The statistical margin of error in both of these papers is small due to the number of respondents. -

KR at 05:40 AM on 12 May 2011Lindzen Illusion #2: Lindzen vs. Hansen - the Sleek Veneer of the 1980s
angusmac - I really don't understand what you are going on about. Hansen's 1988 model had a climate sensitivity that was (in hindsight) far too high - 4.2°C, rather than ~3°C/doubling of CO2. It was run on three different emissions scenarios, which are not predictions of economic and political action, but rather guesses, to see how the model would evolve in temperature. Now, many years later, the emissions that actually occurred are closest to Scenario B. Taking Hansen's (rather simple, by today's standards) 1988 model and re-running it with Scenario B emissions and a sensitivity of 3°C/doubling of CO2 matches the actual progression of temperatures surprisingly well. And if you use actual emissions (slightly different than Scenario B), Hansen's model has a best match at a climate sensitivity of 3.4°C/doubling. That's pretty amazing for an early model - Hansen is to be congratulated! Scenario C? That didn't happen, and is hence irrelevant to current conditions. The only way you see the match to Scenario C you are going on about is if you keep the 1988 sensitivity of 4.2°C/doubling, which has been shown not to be a reasonable estimate. So - you're arguing about an emissions scenario that did not occur, and how that matches to a climate model run with a sensitivity that later proved incorrect. Why are you wasting your time, and everyone elses, with this? -

Harry, Please list for us all the professional scientific societies of the same standing as the American Meteorological Society (for example) who state that human emissions of GHGs are not contributing to global warming. -
angusmac at 05:18 AM on 12 May 2011Lindzen Illusion #2: Lindzen vs. Hansen - the Sleek Veneer of the 1980s
Dana@86, I agree with Albatross. Your diagram makes the forcings absolutely clear. However, let me try to make it clearer by adding temperatures.
Two observations are evident:
• Scenario B temperature predictions are in good agreement with real-world forcings but they fail miserably when compared with real-world temperatures.
• Real-world temperatures do not follow real-world forcings. However, they are in good agreement with the dogleg forcings and temperatures of Scenario C.
Dana, I totally agree that "correlation does not equal causation". However, Hansen (2000) offers an alternative scenario that would change the "bizarre" coincidence of Scenario C into reality and also providing causation. Hansen suggests that the effects of anthropogenic aerosols could balance CO2 forcings. However, he does note that this is a wild card and that current trends are uncertain. I show the forcings from Hansen's alternative scenario below.
Figure 1: A scenario for additional climate forcings between 2000 and 2050. Reduction of black carbon moves the aerosol forcing to lower values (Hansen et al, 2000)
Hansen's 1988 scenarios only consider CO2, CH4, N2O, CFC11 and CFC12. However, it is evident from Figure 1 that the largest anthropogenic climate forcing (due to CO2) could be reduced by negative forcings from aerosols.
Perhaps this is the reason why Scenario C gives good results? If we plugged the negative forcings from aerosols into Scenario B it would result in similar forcings to Scenario C. We would then change the coincidence of Scenario C into a reality of new Scenario B. This new scenario would be able to simulate the post-2000 temperature flattening that is so well modelled by Scenario C.
Tropospheric aerosols look to be the likeliest candidate for a reduction in the CO2 forcing in Scenario B.
China and India have seen huge growth in the last 10 years, most of which is founded on industries that produce large quantities of aerosols. These countries also represent half of the world's population. Therefore, it is not difficult imagine that their aerosol emissions would dwarf Gavin Schmidt's 1940s aerosol blip. Consequently, it is likely that they produce enough negative forcing to cancel out the CO2 forcing in Scenario B thus allowing it to conform to real-world temperatures.

Let's not forget the Oreskes study, which was subsequently confirmed by the Peiser study, despite Peiser's aim to disprove Oreskes. Neither found any valid peer-reviewed studies rejecting the consensus in a sample of approximately 1,000 searched (though it took Peiser a while to admit this). Really, how many studies and surveys confirming the consensus does it take to convince you, Harry? -

Harry @ 41... If you'll note, there are two papers referenced here. Each used different methods to come to their conclusions. Each got near identical results. That's generally an indication that the results are robust. The "skeptics" have yet to put forth any study showing anything to the contrary. They've only used the tactic of big numbers with no denominator (i.e., 31,000 "scientists" without saying how many "scientists" there are). -
dana1981 at 05:04 AM on 12 May 2011Lindzen Illusion #2: Lindzen vs. Hansen - the Sleek Veneer of the 1980s
angusmac - nope sorry, Scenario C would not match up well with the temperature rise if not for the 4.2°C sensitivity. Your whole point is that Scenario C "looks good". It wouldn't look good without high sensitivity. You can't just ignore the aspects of the scenario and model that you don't like. You don't get to have your cake and eat it too. Clearly you don't want to argue for high climate sensitivity, but that is nevertheless exactly what you're doing. Or more accurately, you're arguing for an alternative reality in which one aspect is high sensitivity. -
Harry Seaward at 04:58 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
I still haven't found evidence that the Doran survey was peer reviewed. IMHO the survey was designed to get the desired results. First,the researchers excluded from their survey the thousands of scientists most likely to think that the Sun, or planetary movements, might have something to do with climate on Earth (i.e., solar scientists, space scientists, cosmologists, physicists, meteorologists and astronomers). They sent their survey to disciplines like geology, oceanography, paleontology, and geochemistry. Second, scientific accomplishment or academic credentials were not factors in who could answer. Surveyees were chosen by by their place of employment (an academic or a governmental institution). About 1,000 of those surveyed did not have a PhD, and some did not have a master’s degree. 3,146 (30.4%) responded to the two questions: 1. When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant? 2. Do you think human activity is a significant contributing factor in changing mean global temperatures? Of the overall respondees 90% answered RISEN to Question #1. That is surprising unless the ambiguity of the question caused the 10% to reach further back in history. For Question #2, 82% of the earth scientists replied that that human activity had significantly contributed to the warming. Again, the amibiguity of the question comes into play. Since most skeptics I know (including me), believe that human activity is a contributing factor, their answer depends on the definition of "significant". The value of the word significant should have been defined. However, since the 82% figure might not be convincing enough, subsets were created to achieve the numbers. Cuts were made leaving only climate change scientists. 75 out of 77 scientists (97%) were left endorsing the anthropogenic global warming hypothesis. The authors of the paper were honest in describing their methods. However, when the 97% number is touted as the gospel it is misleading to say the least. -

Dana@83, "contrary to your [my] previous claim, you [I] are indeed arguing for high climate sensitivity." This statement is incorrect and you are aware of it. I state that Scenario C predicts real-world temperatures very well. This scenario has no increase in forcing after 2000 and therefore it has zero temperature rise for 2000-2019 irrespective of the sensitivity value. ( -Snip- )Response:[DB] Accusation of mendacity snipped. You are free to disagree, angusmac. But do not accuse others of lying when it is readily apparent that you either:
- Just don't understand the subject matter
- Are intentionally only looking at information which agrees with your understandings and ignoring everything else.
In any event, many have wasted their time trying to help you gain a better understanding of the matter. I suggest, if the answers here are not to your liking, a different venue might be in the offing for you to gain the clarity you seek.

ExxonMobil is connected to nine of the top ten authors of climate change denial papers, according to a “fact-check” website. Analysis by The Carbon Brief found that the ten authors are responsible for 186 of the over 900 peer-reviewed papers skeptical of man-made global warming. The most prolific climate-skeptic author on the list was Sherwood B. Idso, president of the Center for the Study of Carbon Dioxide and Global Change, a think-tank which the Carbon Brief said has been funded by ExxonMobil. Idso authored or co-authored 67 of the 938 papers analyzed, or seven percent of the total. The second most cited is Patrick J. Michaels, with 28 papers. Michaels has said that he receives about 40% of his funding from the oil industry. Researchers Willie Soon and John R. Christy are both affiliated with the George C. Marshall Institute, which receives Exxon funds, the website found. Another author, Ross McKitrick, is a senior fellow at the Fraser Institute, which also benefits from Exxon funding, the Carbon Brief said. Eight of the ten have direct links to ExxonMobil, the analysis found, while a ninth researcher, Bruce Kimball, is linked to the oil giant because all of his papers were co-authored with Sherwood Idso.dana1981 at 03:51 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming

I've always supposed that both the Anderegg and Doran numbers are a little bit skewed in favor of the skeptics. If I'm not mistaken, both of these papers relies on scientists voluntarily responding to the study. I would suppose that a skeptical climate scientist (your Spencer's and your Lindzen's) are going to be much more likely to respond. Whereas the larger body of climate scientists are going to be more inclined to opt out. I bet the real numbers are in excess of 99% believing climate change is caused by humans.Philippe Chantreau at 03:23 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
Bud, you keep on posting lists of people's opinions. You should instead try science papers published in peer-reviewed science publications. The sicentists whose opinions have been the subject of this post publish in the field regularly, that's why their opinions are relevant. Op-ed letters from astroturf groups don't carry much weight really.JMurphy at 02:46 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
Bud, you need to carefully read and understand the difference between "climate experts" and "scientists" : the former are the latter, but the latter are not necessarily the former. This is so obviously the case with the majority of those on any of your lists (most of whom have no connection with Climatology in any shape or form), that it is surprising that you think they have any relevance to this topic. This is especially so when you think of how many scientists there are in the world and how many have signed these petitions, letters, etc. Here's a hint : the fact that you can mention small numbers (in the same way as is done in that little list shown elsewhere on here, to which link you were referred) - and think they mean anything in comparison to the complete list of papers, studies, scientists, etc - is a sure sign of desperation. However, if you do insist on relying on your beliefs being determined by the smallest number, I'm sure you will be backing these 100 scientists : "I am skeptical of claims for the ability of random mutation and natural selection to account for the complexity of life. Careful examination of the evidence for Darwinian theory should be encouraged." You prefer their view to the majority consensus view, right ?cynicus at 02:36 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
@30, Bud: Hmm, a letter from a non-expert (Holger Thüss studied law and history) doing a full Gish Gallop? Interesting. The letter says he's president of an institute on climate and energy? Sounds mighty impressive and important, but is it really? Well, it turns out that EIKE is only the 'scientific' front of the libertarian lobby organisation CFACT. In other words: it's only one of the many libertarian propaganda outlets pretending to produce 'real science'. It's really an astroturf operation. Why should a letter of a front group for a libertarian lobby organization, filled with long debunked nonsense as documented by Skeptical Science, be listed on this very same site? Maybe as a prime example of how ideologue propaganda works?cynicus at 02:16 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
@14, funglestrumpet. Your comment 'Wake up!' (America) made me recall a speech by r-cal. rep. Dana Rohrabacher. I reckon it complements your post pretty well, albeit in a weird way: Youtube. Pretty sad that people like him are an important part of government.Harry Seaward at 02:15 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming

This letter and list is not on your site. Why? More than 60 prominent German scientists have publicly declared their dissent from man-made global warming fears in an Open Letter to German Chancellor Angela Merkel. (Translated letter copied below) The more than 60 signers of the letter include several United Nations IPCC scientists. The letter urged Chancellor Merkel to "strongly reconsider" her position on global warming and requested a "convening of an impartial panel" that is "free of ideology" to counter the UN IPCC and review the latest climate science developments. Full Text of Translated Letter By 61 German Scientists: Open Letter - Climate Change Bundeskanzleramt Frau Bundeskanzerlin Dr. Angela Merkel Willy-Brandt-Strabe 1 10557 Berlin # Vizerprasident Dipl. Ing. Michael Limburg 14476 Grob Glienicke Richard-Wagner-Str. 5a Grob Glienicke 26.07.09 To the attention of the Honorable Madam Angela Merkel, Chancellor of Germany When one studies history, one learns that the development of societies is often determined by a zeitgeist, which at times had detrimental or even horrific results for humanity. History tells us time and again that political leaders often have made poor decisions because they followed the advice of advisors who were incompetent or ideologues and failed to recognize it in time. Moreover evolution also shows that natural development took a wide variety of paths with most of them leading to dead ends. No era is immune from repeating the mistakes of the past. Politicians often launch their careers using a topic that allows them to stand out. Earlier as Minister of the Environment you legitimately did this as well by assigning a high priority to climate change. But in doing so you committed an error that has since led to much damage, something that should have never happened, especially given the fact you are a physicist. You confirmed that climate change is caused by human activity and have made it a primary objective to implement expensive strategies to reduce the so-called greenhouse gas CO2. You have done so without first having a real discussion to check whether early temperature measurements and a host of other climate related facts even justify it. A real comprehensive study, whose value would have been absolutely essential, would have shown, even before the IPCC was founded, that humans have had no measurable effect on global warming through CO2 emissions. Instead the temperature fluctuations have been within normal ranges and are due to natural cycles. Indeed the atmosphere has not warmed since 1998 - more than 10 years, and the global temperature has even dropped significantly since 2003. Not one of the many extremely expensive climate models predicted this. According to the IPCC, it was supposed to have gotten steadily warmer, but just the opposite has occurred. More importantly, there's a growing body of evidence showing anthropogenic CO2 plays no measurable role. Indeed CO2's capability to absorb radiation is already exhausted by today's atmospheric concentrations. If CO2 did indeed have an effect and all fossil fuels were burned, then additional warming over the long term would in fact remain limited to only a few tenths of a degree. The IPCC had to have been aware of this fact, but completely ignored it during its studies of 160 years of temperature measurements and 150 years of determined CO2 levels. As a result the IPCC has lost its scientific credibility. The main points on this subject are included in the accompanying addendum. In the meantime, the belief of climate change, and that it is manmade, has become a pseudo-religion. Its proponents, without thought, pillory independent and fact-based analysts and experts, many of whom are the best and brightest of the international scientific community. Fortunately in the internet it is possible to find numerous scientific works that show in detail there is no anthropogenic CO2 caused climate change. If it was not for the internet, climate realists would hardly be able to make their voices heard. Rarely do their critical views get published. The German media has sadly taken a leading position in refusing to publicize views that are critical of anthropogenic global warming. For example, at the second International Climate Realist Conference on Climate in New York last March, approximately 800 leading scientists attended, some of whom are among the world's best climatologists or specialists in related fields. While the US media and only the Wiener Zeitung (Vienna daily) covered the event, here in Germany the press, public television and radio shut it out. It is indeed unfortunate how our media have developed - under earlier dictatorships the media were told what was not worth reporting. But today they know it without getting instructions. Do you not believe, Madam Chancellor, that science entails more than just confirming a hypothesis, but also involves testing to see if the opposite better explains reality? We strongly urge you to reconsider your position on this subject and to convene an impartial panel for the Potsdam Institute for Climate Impact Research, one that is free of ideology, and where controversial arguments can be openly debated. We the undersigned would very much like to offer support in this regard. Respectfully yours, Prof. Dr.rer.nat. Friedrich-Karl Ewert EIKE Diplom-Geologe Universität. - GH - Paderborn, Abt. Höxter (ret.) # Dr. Holger Thuß EIKE President European Institute for Climate and Energy http://www.eike-klima-energie.eu/Moderator Response: Your "prominent German scientists" are not necessarily all "climate scientists" as are the ones that are the topic of this post. It would be more relevant if you linked to the list of those 60 scientists; sorry, I can't read German, so I can't find that list on that site you linked to.Bud at 02:10 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
The letter to UN Secretary Ban from scientists demanding disbanding of the UN IPCC is not posted at Meet the Denominator. The Open Letter with long list of scientists to President Obama in the New York Times, to inform him he is wrong about his stated concern about global warming, this letter and list is not posted at Meet the Denominator. The Manhattan Declaration on Climate Change and its long list of scientists and others is not posted on your site. The quotes I listed from many climate scientists including a 38 year veteran analyst at US EPA is not on your site. So, why did you delete these?Response:[DB] Merely copy-pasting articles and/or links amounts to copy-vomit; as such it adds nothing to the discussion. Without adding in context as to WHY you feel the materiel is important and HOW you feel it fits in or needs to be accounted for, then it adds nothing to the discourse here.
If your intent is to not be merely disruptive, then please adjust your comment construction accordingly. Thanks!

Tom @ 23, I guess you forgot about your boys at the IPCC and this statement: "From new estimates of the combined anthropogenic forcing due to greenhouse gases, aerosols, and land surface changes, it is extremely likely that human activities have exerted a substantial net warming influence on climate since 1750." They seem to think there are a couple of other culprits.Bud at 01:33 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
These statistics are just wrong. I have previously attempted posted longs lists of scientists and their positions who oppose the AGW hypothesis, but my posts are apparently deleted by the editor. Would you like me to post them again? These lists would certainly be "on-topic" for this thread.Response:[DB] Poptech's list has been done ad infinitum on the Meet The Denominator thread. Please refrain from reposting them here.

There also is the issue of whether people trust climate scientists to know more about climate than they trust economists to know about the economy. There has been a concerted attack on the credibility of climate science and climate scientists and I don't know if it has penetrated beyond the denialsphere into the general public.gallopingcamel at 01:24 AM on 12 May 2011Infographic: 97 out of 100 climate experts think humans are causing global warming
