  1. Climate Change Could be Expensive for Canada
    What was interesting was that the report only included the costs associated with climate change in their calculations. While the report alluded to the benefits (increased tourism, agricultural production, and decreased energy costs), no monetary value was assigned to them. Likewise, the increased deaths due to warmer summertime temperatures were included, but not the decreased deaths due to warmer wintertime temperatures. In a country where cold is a bigger issue than warmth, I would think this would be rather relevant. Overall, the report focused almost exclusively on the cons, while omitting the pros. It is hard to take something like this very seriously. This is not to argue that nothing should be done because Canada might benefit, but rather reports like this, (-Snip-).

  2. Pielke Sr. Agrees with SkS on Reducing Carbon Emissions
    Having read the RC response and the exchange Dave pointed, and tried to work through some of the details myself, I'm tempted to conclude that the question is meaningless and attempting to answer it will generate more confusion than enlightenment. Although with enough research you might be able to whack the odd case of double counting.
  3. Are you a genuine skeptic or a climate denier?
    Eric(Skeptic) asked my in a discussion on WUWT how I define the term "AGW denier". My definition is quite simple: An AGW denier is a person who argues against, or opposes effective measures to reduce GreenHouse Gas emissions by rejecting well established science. For the purposes of this definition, anything assigned a likelihood of "Likely" or greater by the IPCC is considered well established science. Something considered "Likely" by the IPCC can certainly be wrong, and has as much as a 34% chance of being wrong. So it is certainly rational for somebody to disagree with the IPCC on such an issue. What is not rational it to assume that there is a very high probability that you are correct in that disagreement. That being the case, insisting that policy be based on your belief when that belief has a high probability of being false, and the consequences of basing policy on that belief, if false, are likely to be dire, is irrational. This is particularly the case as most of the viable minority views also imply equally dire consequences, which can be avoided by the same policies. They just allow us more time for implementation. Given this, a person who back low climate sensitivity (say a sensitivity of 1) but insists on an interim policy of lowering emissions while the evidence is allowed to accumulate is not a denier. In contrast, somebody who claimed the climate sensitivity for doubling CO2 was closer to 2 degrees but that this constituted adequate reason to not do anything would be a denier. At the other end of the equation, Doonesbury's (entirely fictional) "Honest Man" is not a denier. Although he fiercely rejects any policy to combat climate change, he does not do so by distorting the science.

    Canada also better start thinking what a 4 degree C global temperature rise means for the habitability of the lower latitudes. It means mass migration north!
  5. Understanding climate denial
    Albatros #102, I'm sorry but you misunderstood. The snipped text dealt with examples of taboo as interpreted by Fromm. By snipping those examples you actually acknowledged their quality! Taboo, taboo: facts are taboo (for denialists that is). This is fundamental, on topic psychology.
  6. Modern scientists, following in Galileo’s footsteps
    #31, no shock at all. The phrase is: 'the usual suspects'. Climate populism is directed (sort of) by a small group of recurring names who operate in an internet hall of mirrors. The Galileo Movement is just one such mirror. Utterly boring. #15, the denialists pounced on that off topic as of shortly before the neutrino's arrived and are boring every decent man stiff with it. Of course not a shred of knowledge is involved. Nor asked for. As of today I call any mention of the CERN experiment offending, it being deliberately off topic re AGW. Protests against this will be met with a charge of stupidity - because it is one or other.
  7. Understanding climate denial
    Something rather interesting and related at the BBC today: Is the internet re-writing history?. It's a discussion of how people are having difficulty separating fact from fiction on the Internet, with examples such as 9/11 denial, Bin Laden alive and other such conspiracy theories. No mention of AGW denial, but it seems clear that one factor in denial is the incredible ease of access to apparently credible sources of information on the Internet.
    "We have something like a Wild West on the internet," says Jamie Bartlett, senior researcher at Demos. There's a huge amount of very trustworthy, academic, good bits of journalism [on the internet], more than ever before, which is extremely liberating. But at the same time, equal proportions of distortions, propaganda, lies, mistruths, half-truths and all sorts of rubbish. It can be very difficult, especially for younger people, to sort the wheat from the chaff."
    The only solution is, as potholer54 is fond of saying, check your sources!

    Norman, you're not seriously taking Joe Bastardi seriously are you? I thought better of you than that. See here at SkS, from ClimateCrocks (see around 7 min), at Climate Progress with lots of links, here by Tamino or on Arctic sea ice. Joe Bastardi has been so often, so egregiously wrong, it's painful to watch.

    Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    Norman, AGW is not going to be the cause of all extreme weather events. It just makes some of them more likely and more frequent. Last year there was the Russian heat wave, this year the American midwest heat wave/Texas drought. You can refuse to see a pattern if you want. Even if the frequency and severity of these events continues to increase, you still will have a case to continue attributing causes to other factors. This is not an area where attribution can be proven without any doubt. It's only one piece of the puzzle. It would be like trying to pinpoint the one and only human behavior responsible for the global recession. So this is kind of a moot argument. On another note, if you say that Anthony Watts is a meteorologist, I assume you have some credentials of his to support it; what are they? Sorry but telling the forecast on radio or TV does not count, it does not make one a meteorologist. I can interpret aviation weather products and translate them into plain language, I understand what they mean, I understand the atmospheric dynamics behind it. That does not make me a meteorologist. A solid relevant background, long time study and the resulting expertise would. Considering that Watts wasn't sure whether (no pun intended) or not carbonic snow might fall on Antarctica, I'm thinking his experise is somewhere between highly questionable and non-existent. Considering once again that, recently, the very author of a paper he misunderstood (on cloud forcing) had to correct him twice on the meaning of the paper, I have plenty of evidence indicating that any time spent to read whatever Watts has to say is wasted. Do you have solid evidence to the contrary?
  12. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    Norman "... all records seem to be broken eventually..." And the longer a record's been kept, the less likely it is to have a record broken when the system in question is stable. That's why the ratio of hot records to cold records is so useful. If weather patterns were holding steady, then the statistical expectation would be for new hottest ever records to be balanced by new coldest ever records - I'd leave it to the statisticians to determine what period would be suitable to confirm 'balanced'. At the moment, it's not possible to do this because in the US the decadal hot/cold ratio has been running at more than 5 to 1. And now we have a single month, August, where the ratio is 22:1, and a whole summer where the ratio is 11.4:1. How is it that we're now in the position that, the longer records are kept, they're more likely to be broken - but only if they're on the hot side rather than the cold?

    Jennifer Marohasy is endorsing these proclamations? What a joke. This is a brave new world we live in. Aldous Huxley must be chuckling in his grave but, really, that's sad. And there are countless people like Saltspringson who buy into the snake oil these charlatans sell. Better keep up the work on SkS.

    rcglinsk - I am sympathetic to your approach, but you must acknowledge Tom Curtis's framing. (Hint, if Tom Curtis ever posts; read and reflect carefully - he is a real gem (one of many) on this site). I think those of us who follow the science do tend to fall into the simplistic arguments you presented (not calling you simplistic), rather than the two paragraph version that Tom Curtis presents. To our detriment.
  15. Modern scientists, following in Galileo’s footsteps
    Stevo @29, Thanks. You made me look closer at the Galileo Movement, and what I read is very interesting/disturbing. Look who the advisors are for the Galileo Movement in Australia: Professor Tim Ball Warwick Hughes Professor Fred Singer Professor Dick Lindzen Bill Kininmonth Professor Bob Carter Professor Ian Plimer David Archibald Professor Peter Ridd Professor Garth Paltridge Dr Vincent Gray Dr Jennifer Marohasy Jo Nova Des Moore John Nicol David Flint Andrew Bolt John McLean David Evans Pat Michaels Joe D'Aleo Viscount Monckton [Source] Their purported guiding principles ironically include: "Honesty: rely on factual data, ensure decisions are based on facts; Fact based science: protect and use science, a key to human progress, objective and fair decisions and freedom" and under "Purpose and Aims" ironically include: "Protect science and restore scientific integrity" Sounds great does it not? But, there is a very big problem with those proclamations, because unfortunately those lofty ethics and goals do not seem to be endorsed or even practised by several of their advisers, as has been demonstrated multiple times here at SkepticalScience and elsewhere. Some of the names on that list shocked me. What are Drs. Lindzen and Gray thinking?
  16. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    muoncounter @106 You quote Jeff Masters "Never in my 30 years as a meteorologist have I witnessed a year like 2010--the astonishing number of weather disasters and unprecedented wild swings in Earth's atmospheric circulation were like nothing I've seen." This is not a scientific position, it would be considered an expert opinion. In his post he does bring up some other years to compare to. This approach does not give one the true extent of the weather conditions. One claim was that a storm over Minnesota had a pressure reading that was the lowest since records were kept (all records seem to be broken eventually). He compared one other year that was a previous record. What is missing is a historical view of a large number of low pressure readings to determine it this reading was way off the charts or just a little above what has already been taking place. Two other meteorologists do not share Jeff Masters Expert Opinion. One is Anthony Watts and the other Joe Bastardi. Both of them are meteorologists that have been in the field for many years. They would see similar data that Jeff Masters is exposed to. Why don't they see this same extreme year?
  17. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    Bibliovermis @107 "You are eyeballing charts and declaring that they support your already held convictions. That is how you can be wrong by compiling data; fallacy of composition and confirmation bias. You are picking any iota and clutching it, such as total days over 105 in Dallas, to prove that the observed weather is not unusual." I am not claiming the observed weather is not unusual, the drought in Texas is extreme. It is still unusual as such droughts do not occur often, but they do, and eventually you will have one that was worse than the previous ones. I would suggest you try the challenge I gave muoncounter in post #90. Do your own "eyeballing" of two animation runs of NOAA drought conditions for US. See what you think.

  19. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    DB @106 and adeladay @85 Both of your posts are similar and I would expect to see warmer weather patterns around the world as it has heated by about 0.8 C since pre-industrialization. Warmer temperatures are not necessarily extreme. You can have patterns that make one part of the globe very warm (which has been happening as long as temperature records have been taken, in the area of Omaha NE the record high temp is over 20F above the average high temp). In my area as a low pressure system approaches from the west, it rotates counterclockwise first will pull up warm moist gulf air into the region raising the temperature maybe 20F above normal, than as the low passes it will bring down cold air from the north and drop the temp about 20F. These temperature swings are not like a random dice throw. They are predictable and have an established linking mechanism. One thing is certain in all the variations of temp. When all added up the amount above the historic average is about 0.8 C. If half the globe is 5 C above normal, then the other half has to be 4 C below normal to balance the total anomaly for the globe.
  20. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    DB @101 Your statement: "You discount adaptation as a human response to minimize damage to property and loss of life due to severe weather and constantly cherry-pick isolated events to support your adopted position. There is nothing scientific about that approach at all." Cherry=picking "Cherry picking, suppressing evidence, or the fallacy of incomplete evidence is the act of pointing to individual cases or data that seem to confirm a particular position, while ignoring a significant portion of related cases or data that may contradict that position. It is a kind of fallacy of selective attention, the most common example of which is the confirmation bias. Cherry picking may be committed unintentionally." What I am doing is not cherry picking, it is random picking. It would be like reaching blindfolded into a basket and pulling out cherries at random and presenting this. I go to the NOAA site looking for past examples of severe weather events. I just picked a date a random that was far away from recent times and presented it to demonstrate that extreme weather takes place maybe more often than a randomized statistical approach would allow. I do not think extreme weather is the same as a random event like dealing a straight flush from a deck of cards. My perception (from what I have read on meterology is that extreme weather occurs because of some known atmospheric event...it would be closer to someone manipulating the cards in the deck to favor the dealing of a straight flush). I am not convinced that one can use random event statistics to determine the likihood of extreme weather (tornadoes, hurricanes, floods, droughts, wind)
  21. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    Norman, My proposed disparity metric is on the Dai After Tomorrow article. You were making the assertion that the current extreme dry and extreme wet weather is not unusual by providing a few images. I want to create a more robust way of validating such an assertion.
  22. Increasing CO2 has little to no effect
    phantum#75: "what about the interaction of the Earth's and Sun's magnetic fields (solar wind)? this effects the temperature as well" If you have data to substantiate this claim, please provide links to it on the cosmic rays thread. I've looked and haven't found much of any quantitative information. "maybe we should be more worried about the things we cannot change than the ones we can." That is an interesting suggestion. After we've worried about the things we cannot change for a while, what do you propose we do about them?
  23. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    Bibliovermis @111 "I would appreciate your input on the quantitative PDSI disparity metric." I will have to claim stupidity on this one. I am not sure what you are asking and could not find a link to give an explanation of what you are asking.
  24. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    KR @108 * Earthquake numbers are underestimated due to better building codes. I am not making a firm statement on that one. I do know that in earthquake zones they do have building codes designed to reduce death and destruction and can work fairly well for the more numerous magnitude 5 quakes but would probably not help much in a 7 or above. Here is what my post said. "I have one possible explanation. Not necessarily a good one, maybe you won't accept it. Here goes." It was just food for thought, not an elaborate explanation for the difference between the disasters. I had a debate with Tom Curtis on this question on another thread Post 83 on this thread.
  25. Modern scientists, following in Galileo’s footsteps
    @25 Saltspring Person- You seem to be unaware of the religious aspect of global warming rejectionism. Both Spencer and McKitrick are signatories to the Evangelical Declaration on Global Warming, Cornwall Alliance Signatories stating among other things that: 1.We believe Earth and its ecosystems—created by God’s intelligent design and infinite power and sustained by His faithful providence —are robust, resilient, self-regulating, and self-correcting, admirably suited for human flourishing, and displaying His glory. Earth’s climate system is no exception. Recent global warming is one of many natural cycles of warming and cooling in geologic history. and 1.We deny that Earth and its ecosystems are the fragile and unstable products of chance, and particularly that Earth’s climate system is vulnerable to dangerous alteration because of minuscule changes in atmospheric chemistry. Recent warming was neither abnormally large nor abnormally rapid. There is no convincing scientific evidence that human contribution to greenhouse gases is causing dangerous global warming. Which leads to your point 1 about scientists suppressing other scientists. McKitrick and co-author MacIntyre have conducted the primary attack on Michael Mann's Hockey stick. Their statistical tools have been shown to be corrupt: Summary of Analysis of M&M with links to peer reviewed publications at the same time- someone was attempting the equivalent of a DoS attack on Hadley by flooding them with FOI requests. SkS discussion of 'ClimateGate' Was this McIntyre's doing? So the question is who started trying to suppress who first? What other suppression do you have in mind? Is there any supression currently going on? The rest of your points have been addressed by others, but I'll add that for there to be a change of opinion in 5 years, the data ought to be on the ground now, bedcause it will take time to replicate it and explore it. So what's your unrecognized smoking gun?
  26. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    KR @108 I think best to break up your bullet and respond to each individually or the post will get too long. * Records of disasters are biased by population shifts/changes, and no actual event changes have occurred. Hence the insurance information and FEMA disaster records are inaccurate. This postion is based upon the research of Pielke. Disaster as a proxy for extreme weather events is questionable. Besides Pielke research into the matter I have a thought experiment for you to consider on this issue. Some big disasters are floods, costing billions and killing people caught in the flood waters. Others fires. Hurricanes and tornadoes. The thought experiment to demonstrate a point. Consider the idea that insurance companies require changes before they will insure property. Here are the changes. In fire prone areas the property owner is required to have at least 200 feet of sand between their property and the nearest forest and a sprinkler system to put out any embers that approach the property. All home owners in floodplains are required to have their homes on stilts high enough so the bottom of the property is above the highest recorded flood stage (Galveston has homes on stilts to save the property from storm surges). People living in tornado alley will be required to tornado proof their property ("One construction method has been shown to stand up to 250 mph winds, which provides you and your family with far more protection than conventional wood framing. That construction method is called ICF (insulating concrete forms")). Roofs made of hail resistant material in areas prone to such events (Wyoming for instance). People are not allowed to build expensive property on coastlines prone to hurricanes and storm surges (low cost cabins would be okay). Along with the property saving methods described, life saving knowledge would be far more widespread (don't go outside when lightning is close, stay off roads with water running over the top, no hurricane parties, etc). Now with all these in place the number of disasters would drop off considerably but the extreme weather would be the same. Trending disasters would not tell you anything about what the weather is actually doing. A system of reporting that does not rely on property values and human fatalities would be the only actual scientific method of determining if weather related events are actually trending upward.

    tblakeslee, It amazes me that you'll fight and claw to prove that a long-shot theory like GCR is it, while you'll dismiss overwhelming evidence for theories that you don't want to be true. You'll take a graph off of a disinformation site that is riddled with errors. If you were at all skeptical, you'd look at half of those pages on appinsys, see for yourself how wrong they are, and know you couldn't trust anything there. Your two graphs are from the 2005 paper by the infamous Willie Soon. Read about his funding sources here. Read about his polar bear debacle here. Or read about him right here at SkS. I wish I could find someone who bothered to debunk that particular paper, but it seems to have been pretty much just ignored by everyone, probably because (a) the author is not credible and (b) the argument has been debunked in so many ways that a silly attempt to "argue" a strong solar correlation in the way he did is itself pitiable.
  28. The Dai After Tomorrow
    Bibliovermis: Liu et al 2011 has a nice analysis of PDSI and 'Standardized Precipitation Index.' They forecast (using standard model scenarios) a significant increase in severity and probability of drought. The key is figure 12, which displays the PDFs of PDSI for the past and the future. 1950-1999 shows a near normal distribution with mean value slightly above zero, while 2050-2099 displays an abnormal PDF with mean value below zero and left tail reaching towards much lower PDSI. This indicates that future drought is likely to get more severe and frequent, as projected by SPI under A2 scenario. Note: PDF is probability distribution function.

    KR @108 and skywatcher @109 KR I did like your bullet format but I am not sure my button was zapped. I will repost your bullets and then defend my position, it this is okay. KR's Bullets. *Extreme weather has not increased. Perhaps I give you the perception that I am saying that "extreme weather has not increased" but the reality of my posts does not support this claim. In post #30 I do state my position: "My position on this topic is that there is not enough data to make a declaration of certainty on the topic. I think earlier data on severe weather events was not as fully reported as today. I do not think there is adequate accounting of severe weather events to take a strong position that the number and intenstiy of severe weather events has certainly increased. I am not stating it has not. I am making the case that there is not enough good reliable data to make any claim of certainty on this issue at this time and we may not know for many more years. Your contention is that if we wait to see if it is getting worse, it might just be too late." And in post #60 "This thread is not about global warming (evidence would suggest a degree or 2 of warming depending on your temperature scale). It is about extreme weather events. Are they increasing because of the global warming? That is what I question. I am not saying I am correct in my position. I just of the opinion that at this time there is not enough good, reliable data to make a sound judgement upon this issue. I see some blogs throw out the year's worst weather events and tell me things are getting worse. Maybe they are, I just need more evidence than one or two years worth of data. Need a lot more from a lot more areas and over a lot longer time period. Need a consistent way of logging an extreme event. I think monetary damage is not a good one. Hail size, area of coverage, duration of hail storm. That is much more scientific. Get enough of this data compiled and you can answer the question in a sound scientific way based upon solid data."

  30. The Dai After Tomorrow
    A discussion on PDSI disparity, very dry & very wet at the same time in different parts of the same landmass, is being migrated here from the Review of Rough Winds article. I am looking to create a PDSI disparity metric to quantitatively say whether a given drought & flooding episode is unusual in the observational record. The discussion was about the 2011 Texas drought happening alongside flooding in other parts of the US, but the general principle could be applied around the globe using the Dai dataset at Palmer Drought Severity Index (PDSI) from NCAR. The data set for the US analysis is the PDSI Divisional Data linked below the map on NOAA: Historical Palmer Drought Indices. direct link: PDSI data (3.8 MB text file) The NOAA PDSI dataset is composed of 344 climate divisions. U.S. Climate Divisions division area list Now that the data sources are referenced, here is my concept for the disparity metric. 1) Order the list numerically by value. 2) Match the list off into 172 top/bottom pairs; 1-344, 2-333, ... 172, 173. 3) Take the absolute difference between the value pairs and multiply it by the summed area of the two climate divisions. 4) Sum the 172 values from #3. - reference value: 8 (difference between extreme drought, -4, and extremely moist, 4) x U.S. contiguous area 5) Divide #4 by the reference value. The final result is a scalar value between 0 - 100+%. Low values mean similar dry/wet conditions across the nation, while high values indicate large areas of opposites of extremes. The metric can be greater than 100% since PDSI values are not capped. Any suggestions, arguments against or confusion?

    DB @96 My contrail concept: "The 0.01 watts/meter of contrails is its effect on the entire globe (the contrail coverage of the globe is small) but in localized areas that may have a high degree of contrail formation (based upon upper atmpospheric conditions) the effect can influence the local region (still a small part of the globe) to a greater degree." Your response to this postion: "For example, your Black Knight routine after the lack of evidence supporting your position on contrails was pointed out to you," I did find some evidence supporting my postion. Contrail information. Look at the concluding remarks. Regionally contrails can add 4 watts/meter^2 radiative forcing. Yet over the whole globe their effect is very small. This is very close to my postion on contrails.

It is the comments such as: It is cold in everyone's back garden. AGW nutters can manipulate the numbers all they want, that is still a fact. These comments of accusation I flag and feel motivated to address. With regards to your comment on Happer's Senate testimony.

    cRR Kampen@102 Thank you for your 'hear, hear' to my comment #37. It appears to me that some people who publish just plain wrong materials may not themselves be in denial of the science. Just as one may make money from remedial teaching, so one may make money from anti-remedial teaching. It appears to be part of the human psyche that we are primed to reject any evidence that we are not in control of our environment. An author of anti-remedial literature is thus likely to make more sales than the author of remedial literature. By anti-remedial I mean that which reinforces erroneous beliefs. For lovers of long words: I would call that kind of publishing activity 'fortipensatory therapeutics' - the therapeutic reinforcing of wrong but comforting ideas by inverting published scientific facts. Fortipensation is of Latin derivation and means 'strengthening of belief' but it is also an atrocious pun from a WW1 joke about errors in communication. A message is transmitted and re-transmitted over poor connections until it is completely garbled. "Send reinforcements, we are going to advance." becomes "Send three and fourpence, we are going to a dance." Three and fourpence - 3 shillings and 4 pence - is forty pence in Britain's old money system.

    rcglinsk @106, you are inaccurately framing the debate. You wrote:
    "We need to put substantial taxes on gasoline so people don't drive nearly so much and pay more for new cars with better mileage. This is necessary to prevent damage to coastlines which will not happen in your lifetime."
    Based on the science, the correct framing is:
    "Failure to reduce greenhouse emissions by at least 50% within the next twenty years will almost certainly result in the complete loss of major eco-systems such as the Arctic, the Amazon Rainforest and the Great Barrier Reef. Such massive eco-system loss along with direct effects on human productivity is likely to result in a collapse of the international economic system which will make the great depression look like a boom in comparison. If you are under the age of fifty, this is likely to happen in your life time. The human population has never been greater than 200 million when the Earth's mean temperature has been outside a narrow band of about 1 degree C. We are already at the upper end of that band and within the life time of people being born now we will be as much above it as we where below it during the last "ice age" (glacial). There is no reason to think the Earth's carrying capacity for humans will remain at is high multi-billion level during that transition. So perhaps it is time to start doing something about it now.
    Unfortunately the politicians, even the Democrats, refuse to listen to what the science is saying.

    @107 Mr. Hartz - Please allow me to try to convince you of the merits of not separating the debates. (One caveat, I will assume you are American because I don't think you've been posting in the middle of night in England) 1. Upon learning of a need to sacrifice some people will take up the burden as a badge of nobility. Most will not. The noble might tell the rest "your material desires put our collective future at risk, take up your part of the burden as a moral obligation." I would be surprised if that had ever worked in all human history, absent a war. Asking people to invest in advanced technology is much more likely to garner support. I think the brain places a greater weight on achieving a desirable outcome in the present than on avoiding a harmful outcome in the future. It's more effective to tell people invest, get new technology than sacrifice, avoid future harm. 2. The policies currently on the table, the only ones that would foreseeably be implemented (in the US at least) stand a some risk of not significantly curbing US CO2 emissions. Say carbon permits are implemented. Who sets the number of permits? It's very unlikely to be a climate scientist; much more likely to be a banker or a corrupt bureaucrat. And think about what will happen to permit levels when Republicans control the whole government. They'll cynically flood the market, create an economic bubble, and then say the democrats will destroy jobs if they reduce permit numbers. If the point of fighting the good fight in the climate debate is to prevent future harm, I submit that to actually succeed (at the least in the US) one must win the fight on the policy front and must have an alternative to carbon permits. 3. You can't win the public debate on climate science. There are no Earths to experiment with, there is not class of Earth-like planets to conduct epidemiological studies of, there is only what science must (and has) resort(ed) to. That is a massive advantage for naysayers and nitpickers. Think about the sheer number of pages on this website, it even has a top ten list. 90% of the complaints are [redacted for politeness], but even the IPCC has to include low and high climate sensitivities in their forecasts because there are real uncertainties. Yes, everyone is completely straightforward about the uncertainties, and everyone works to reduce them. They still exist. That's enough to keep biased laypeople biased. The nitpickers will always win the public debate. It's not fair. Life's not fair. You can win the 4th generation nuclear vs. coal debate. You can win the debate over whether to import mideast oil or use biofuels and fuels from thermal solar. You can win a debate over hybrid cars and gas mileage. You might even win a debate over whether it would be more fun to drive through rush hour or sit on a train/bus and play on your ipod through rush hour. /endlist As to typical denier tactic, I'd prefer peacemaking pro-nuclear denier who sees room for middle ground. Never waste a crisis, after all. I think the policy Hansen proposed in this essay is a good starting point for compromise. http://www.columbia.edu/~jeh1/mailings/2011/20110729_BabyLauren.pdf I can only disclaim I don't think it did any good for him to be so grandchildish.

  43. CERN - Saying Nothing About Cosmic Ray Effects on Climate
    Skywathcer @113, here is Tamino's graph of gistemp arctic overlaid on a detail of the Krivova reconstruction. Graphic techniques only are used, so I do not claim an exact match, but it is clear that solar forcing is not the main player at any stage in 20th century, and runs counter to the temperature trend post 1980. Sorry about the lack of clarity of the gistemp data. I had to significantly compress its vertical scale to match it to the solar data.
  44. Review of Rough Winds: Extreme Weather and Climate Change by James Powell
    Thanks for the pointer. I call the article on Dai more appropriate than this one, since the Dai dataset will be used for a global analysis. Norman, I would appreciate your input on the quantitative PDSI disparity metric.

    skywatcher (#108), perhaps Spencer and Lindzen do not consider paleoclimate to be convincing evidence of high sensitivity. I don't as I explained on the low sens. thread I would agree with yocta. (#110) in part because not many people know or care who Lindzen is. But yocta should also be careful to read Happer's Senate testimony because Happer actually says "it is warming" and "it is us" and then launches into a long series of minimizations and outright fabrications.

    addendum to last paragraph: (bad cut and paste job in editing) The views I see involve conspiracy and coincidences and often follow the "it's not warming" or "it's not us" argument. I personally believe these are the ones to be most scared of and focus a good bit of attention to since as one can see in the Public Figures quote page on SS that these views are mirrored by policy makers.
  48. Modern scientists, following in Galileo’s footsteps
    Saltspringson@25 Re: your point 3 - The belief in a stable, self-regulating climate was overturned when a majority of scientists accepted the geological evidence of multiple former ice ages such as could only have been caused by substantial long-term (geologically speaking) global cooling and warming phases. The first scientific paper showing evidence of ice ages and temperature changes was presented by Ignaz Venetz in 1821 to the Swiss Natural Science Society. Jean Charpentier did not believe Venetz until shown the geological evidence at first hand. Charpentier promoted Venetz' discoveries but in turn was not believed by Louis Agassiz until Charpentier showed him the evidence at first hand in 1836. Louis Agassiz, a fossil expert, published his first paper on glaciers, ice ages and 'global cooling' in 1837 and devoted the rest of his life to studying and promoting the evidence of ice ages. Multiple lines of evidence of former ice ages and of their causes is the foundation of climate change science. In 1895 the list of possible causes (solar changes, orbital changes etc.)was found not to sufficiently account for the global temperature changes which could trigger or end ice ages. And then Arrhenius published his demonstration that CO2 was the primary missing factor. The fact of former ice ages is often used by climate change skeptics who think they are disproving climate change science thereby. Evidence which strongly supports a theory cannot, according to common sense logic, be used to refute it. Acceptance of ice ages as fact implies acceptance of climate change as fact. Is this an acceptable alternative to the phrasing which you criticize? - The discovery of the ice ages overturned an age-old belief that the climate is naturally stable in the long term; the skeptics seek to restore that belief.

    @ 6 John Russell Thanks, for that. I think you are quite right that writing in a style that may convince a 3rd party by their monitoring of the discussion would be the best approach when dealing with a hard-line 'skeptic'. I have lost track around post 60 as this is a long discussion but I would have to agree with cRR Kampen @ 29 with his view on denialism. It seems most people on SS concentrate on the big fishies (Spencer, Lindzen etc) and focus on their arguments on climate sensitivity but certainly the ones I encounter on news sites, You Tube etc often would never get to that higher level of skepticism in their arguments. The views I see involve conspiracy and coincides and often follow the es we should be most focused on tend to lead towards the "it's not warming" or "it's not us" style. I personally believe these are the ones to be most scared of and focus a good bit of attention to since as one can see in the Public Figures quote page on SS that these views are mirrored by policy makers.

    While I have respected the priority of SkepticalScience.com to focus on scientific issues, I'm pleased, nevertheless, to have seen a recent shift toward a more open and realistic approach toward the phenomenon of denialism, which I have long advocated. Scientific evidence alone is often insufficient to persuade individuals who find the (apparently) conflicting scientific evidence confusing, or simply filter out information inconsistent with their beliefs. For this reason, I believe it is equally important to directly address the nature, tactics, and origins of denialism. Denialism must be distinguished from skepticism, which is an essential element of scientific method. Denialism in its many forms is not about science or evidence, although this is superficially its focus. Rather, denialism is a phenomenon rooted in human psychology. We are social beings, and denialism is a manifestation of this, being strongly tied to political and social ideology, group affiliation, and collective beliefs. The fact that most denialists are unaware of the degree to which their beliefs are shaped by ideology is not surprising. The human mind imposes powerful filters on how we perceive and interpret the world around us. Skeptics may rationally question certain details of the scientific theory. AGW Denialists, however, reject AGW in toto, not on the basis of evidence, but because denial is consistent with certain beliefs they already hold. Underlying ideologies effectively dictate where they go for information, and which sources they tend to trust. Denialism serves to reassure its adherents that the things they believe in are right and true, while certain things they find threatening are not real. Ironically, many AGW Denialists simultaneously embrace an irrational fear of things that are not real, particularly that AGW represents an international conspiracy aimed at stealing their wealth and taking away their freedoms. While skepticism remains an admirable and essential element of scientific reasoning, denialism is a rather childish and petulant way of dealing with complex, challenging issues, yet it is a powerful force that has brought low even persons of keen intellect and education. It has long been anticipated that AGW Denialism would crumble before the weight of scientific evidence, yet the Denialist movement has been surprisingly resilient. The internet, as well as certain elements of the “faux news” media are largely to blame. The ongoing collapse of the northern ice cap has made it very difficult to continue to deceive people who have little in-depth understanding of the underlying science, but are willing to be persuaded by direct evidence. The fact that it has taken so long is disappointing, yet it's better late than never. I would hope that there are many who would learn from this experience, and begin to mistrust their beliefs on other issues, as the political ideology that gave rise to a AGW Denialism is “in denial” on many other issues as well. Unfortunately, in my years of fighting against AGW Denialism in the petroleum geology community, I’ve found that the most ardent denialists will never admit to being wrong about anything, ever. The typical response is to change the subject, or just silently slink away. While this can be frustrating from a rhetorical perspective, at least they will do less harm.
