  1. Glaciers are growing
    "Sublimation may indicate a change in atmospheric air streams to a drier air. Glacier melting from increased warming via conduction is certainly a factor, not necessarily air temps increases." And the evidence for this what? And where is the extra heat from conduction coming from? Almost of all of glacier melt is in the ablation zone, and in many cases, ice loss is accelerated by calving. As to the sudden appearance of volcanoes causing melting where it wasnt before, leaving aside the question that heat flow from volcanoes is very localised, in what ways would such melting be different than that caused by warming? And how does that compare with observation?
  2. Lindzen's London Illusions
    75, jzk, "His conclusion that because summer radiative forcing doesn't seem to be changing CO2 must not be a factor is.." ... utterly ridiculous, and you've bought it hook, line and sinker. What do you think is melting Arctic ice, and extending the melt season, if not increased temperatures? What is it, ice gremlins? That's the cherry pick... choose the statistic that appears, on the surface, to support the position you want people to select, and ignore the obvious, which is that it can't possibly be true. First... CO2 / GHG can be a factor if part of that influence is to raise spring, fall and winter temperatures and limit ice recovery as far as depth, not extent. This actually makes a lot of sense, because the thing about the Arctic in the summer is the length of the day and therefore the amount of direct solar radiation. In that situation, the importance of the GHG effect is diminished. Switch that to the long winter, and low incidence spring and fall, and suddenly GHGs become important. Of course, Lindzen knows that, even if you don't. Second... as explained, summer temperatures can appear more normal than otherwise because a whole lot of that energy is going into melting ice instead of raising surface temperatures. It takes 80 times as much energy to melt one gram of ice as it takes to raise 1 gram of water 1˚C. Third... as Albatross pointed out, what temperatures are really being measured and considered? We don't have good coverage of the Arctic, so you can't even really say that what he's saying is true. The bottom line... Arctic ice is melting in an alarming fashion, so I don't need a thermometer to tell me that the Arctic is warming, and anyone like Lindzen who is sticking a thermometer in your face and crowing "see, see, ignore that CO2 stuff, it's nonsense" is obscenely manipulating you.
  3. New research from last week 10/2012
    JE Solheim as in http://junkscience.com/2012/03/14/solheim-the-long-sunspot-cycle-23-predicts-a-significant-temperature-decrease-in-cycle-24/ and yes that Humlum... Ole! Ole! Seems I just got my self banned from junkscience for having the temerity to rip apart (using facts nicely, I might add!) every posting on oil/energy over the past few days... I guess you are not allowed to respond to Milloy calling Obama a Marxist... And saying Inhofe is a hypocrite for not adhering to Isiah might not of helped... ;-)
  4. Roy Spencer's Bad Economics
    "Now we are at a point where we are trying to persuade people that radical changes need to be made to our energy infrastructure--in effect, our fundamental way of life." I disagree strongly with that. People don't see the infrastructure at all when considering their "way of life". All they want is for the power to come on when they hit the switch. And if building or retrofitting housing with higher standards of insulation and other energy saving measures results in more comfortable lives with lower power bills, that's a win. In rural areas, communities often favour wind and similar renewable power generation because it keeps jobs and livelihoods in areas which would otherwise lose population.
  5. Roy Spencer's Bad Economics
    "The alternative, more half-measures and a general paralysis, will otherwise likely persist until the 2016 election cycle." I have no idea how your political scenario might pan out this year and the next. But there will certainly be at least one El Nino year between now and 2016 and there will probably be a near-as-dammit-is-to-swearing ice-free summer period in the Arctic by then. A hot period will have horrible fodder from some places for TV news - a re-run of Russia or Europe's worst summer, Australia and/or the Mediterranean and/or California burning or poor old Pakistan getting drowned out again - will have an effect. And if there are any repeats of hurricanes dumping unprecedented rainfall in those unexpected more northerly regions of the East Coast of the USA, the power of those messages will be mutually reinforcing. In my jaundiced view, getting the message in the second decade of this century will be on the too little, too late spectrum. But I suppose it's not as bad as the next decades.

    @DB, Just want to give you a heads up that the Talk Origins people who combat creationism in the U.S have a wonderful index of debunking articles. I have found it a joy a to navigate. An index like that would be a real help.
  7. Roy Spencer's Bad Economics
    Why Roy Spencer holds his position is not clear to me, but the appeal of his argument to many working and middle class Republican (and I'm sure many similarly situated Democratic voters) in the US is readily understandable: They already have suffered serious drops in their living standards from changes that have impacted American society over the last thirty or forty years. Some of these changes, such as free trade, were claimed by the government to be good for working class people, but that has not turned out to be true for many people, including many middle class voters. Now we are at a point where we are trying to persuade people that radical changes need to be made to our energy infrastructure--in effect, our fundamental way of life. And the plain truth is that the changes that are necessary will result in economic pain. Arguing that suffering the pain now, rather than experience much more pain some nebulous number of years or decades down the road is a very hard sell. Remember, the same part of the political spectrum that is in denial about the threat posed by climate change is also opposed to big government in a general sense. Many of the people in this segment of society have bought into the fantasy that if only big government can be dismantled, they will suddenly be free to become fabulously wealthy. With thoughts like these dancing in your head, I suspect it is much easier to listen to people like Spencer (including Rush Limbaugh, and the various other voices on that side of the debate) who, claiming to speak from positions of impeccable authority, argue we should not change rather than go down a path whose advocates admit has costs associated with it that are measured in the trillions of dollars. Many of the things that scare me about global warming are also less likely to scare people focused on narrow self-interests, like the rising cost of gasoline, which somehow Obama is being held responsible for. For example, only about 1% of Americans make their living as farmers, so those who don't have intimate connections to farming are not likely to worry about the predicted future the US faces of a much higher frequency of agricultural droughts for almost the entire lower 48 states if things keep moving along on the present course. Similarly, few residents of interior states have immediate reasons to worry about the potential for a future global sea-level rise of a meter or so by 2100, and some of them probably think that many residents of cities like New York, Boston, Washington, DC, New Orleans, and Miami may well deserve to be deluged. Also, when politicians like Obama advocate investing in alternate energy sources, few Americans can see a direct benefit to having wind turbines installed in areas they consider scenic when they know that the installation will also directly result in a higher cost at their electric meters, and even fewer like the idea of having a nuclear power plant built in their proverbial back yard. Finally, when anyone tries to argue that the best way forward is to impose a carbon tax, most of these Americans hear that dirty three letter word and know they don't agree with anything that a person advocating such a step may say. Many people in the US, from all points in the political spectrum, including, I suspect, many politicians, are quite simply woefully lacking in the knowledge or interest necessary to assess the merits of the debating points in this particular argument, and thus the person who offers up a rosy scenario where radical change is unnecessary has a huge advantage. For these reasons, I feel Spencer's message has a deep appeal. This situation points to the profound dangers present in a democracy where the voters are poorly informed. Since the US is a giant in this quagmire, I believe a necessary step is for President Obama, either with the cooperation of the Congress, or without it, to begin an official and extensive formal review of the science and economics, bringing in experts from all different fields to testify about the science and the consequences of action and inaction, etc., and he should by all means include accredited dissenters since we want and in fact need their bad arguments to be exposed, but the initial goal of this lengthy course of public hearings would be to get on the record the best arguments from both sides in a public forum that the deniers cannot simply dismiss as the workings of the UN. In short, I think we should want our scientists to debate the other side's scientists quite visibly and loudly. Over the course of 6 months or so of hearings and testimony that explores all the details we are familiar with on this site, with interim reports being released on a steady basis, and as much televised coverage as possible via C-SPAN and various news outlets, Obama could do a lot to get the debate moving. I even think this kind of bold action may be necessary if he hopes to win a second term, since the half-measures he's adopted or advocated to date have of course made it look like he wants to do more if given the chance, so the opposition uses that suspicion to gin up its base, even while he holds back the really weighty other shoe. I'd rather have Obama damned for something he did than condemned to failure because he's afraid to even open up the debate. For that matter, if he barely wins a second term without bringing this debate into the open before that victory, I suspect he will not be able to do much at all given the gridlock in Congress. For these reasons, I feel the debate in the US desperately needs to come out into the full glare of political daylight, since even if it costs the Democrats the Senate and the White House this fall, the seeds of change it will plant will be increasingly hard to ignore as climate change proceeds apace. The alternative, more half-measures and a general paralysis, will otherwise likely persist until the 2016 election cycle.
  8. Roy Spencer's Bad Economics
    About figure 1: -When was it taken?(what month of the year? seasonality is important because a lot of pollution comes from fires during the dry season in tropical forests ) -Roy Spencer blames the wind above the dust for the small particulate matter(PM) 2.5 pollution, but that should liberate medium-sized particulate matter, not small PM 2.5. And the Spencer statement is inconsistent with the fact that other deserts (Western North America, Namibia-Kalahari in South-West Africa, Gobi Desert north of China, Central-Western Australia) there is little PM 2.5 pollution. So: What is the source of of PM 2.5 pollution in the Sahara Desert and Arabic desert?

    Glaciers are growing
    [DB] I disagree, there is an active under the ice volcano in the area where the warming is graphically shown. Your reference did not address Antarctic underice/sea volcanoes.
    Moderator Response:

    [DB] "there is an active under the ice volcano in the area where the warming is graphically shown"

    Citation, please?  Also please quantify how much heat is melting how much ice causing how much warming.  Please include in your citation the paper the peer-reviewed study you cite appeared in.

    "Your reference did not address Antarctic underice/sea volcanoes"

    Quite frankly, it doesn't need to.  Volcanoes are not magical creations possessing the higher intellects needed to discern between hemispheres, like say, polar bears and penguins.

    [Not DB] In my opinion, volcanoes are not really on topic for this post, which focused on the plain and simple fact that glaciers overall are not growing. Evidence for and against that particular point is welcome.
  10. 2012 SkS Weekly Digest #10
    @Scaddenp, No problem. The irony is that about an hour ago I did the same thing on some poor soul over at Scientific American, but with more venom. I misread the commentator's sarcasm as being earnest and immediately unleashed a barrage of out raged rhetoric. It was not until I actually read the thread that I realize the mistake. I think we are all a little traumatized by this wave of anti-science stupidity and need to take a few breaths and moments before hitting the reply button.
  11. Henry justice at 08:15 AM on 15 March 2012
    Glaciers are growing
    scaddenp: Thanks for your comment and reference. I believe action was taken to replant the forest. Sadly, it may prove very true that it will not do the trick. Sublimation may indicate a change in atmospheric air streams to a drier air. Glacier melting from increased warming via conduction is certainly a factor, not necessarily air temps increases. For the last 200 yrs the slight upward temp trend has been declared at about +0.5 deg C. Increase in IR (i.e.8-15 microns) will cause 10 deg F insol (Bragg Equation foldback effect) and yes, that will cause melting. But that is for snout ice, not hard ice underneath the glacier, which might be at a much lower temperatue. So, what are we talking about for all these melting glaciers, softer snout ice or hard glacial ice?
  12. 2012 SkS Weekly Digest #10
    @JH, It is new as a new pseudo-fact. In some ways it is simply a re- manufacturing of the CO2 can't cause much or none at all warming. I had never seen that argument before and so I thought you guys would want to be alerted to it. Off topic: I do not know if this would be worth the time and effort but is there anyway you guys could consider categorizing the climate myths alphabetically and by topic such as Cryosphere, Greenland, etc? I think the more ways individual articles are cross referenced the easier they will be to find.
    Response:

    [DB] Myths are categorized also by Taxonomy.  The alphabetical thing will be taken under advisement, thanks!

    Tom Curtis: Antarctic warming- Could some erupting undersea volcanoes in the warming areas of West Antarctica be the cause of the warming there?
    Response:

    [DB] There simply is no evidence to support that assertion.  And much to the contrary (example here).

  14. Glaciers are growing
    So Henry, perhaps you would like to look at Mt Kilimanjaro for some discussion on this. Also: "Many glaciers have sublimated even when the temperature above the glacier was still below freezing" Now why do you think this is? You seem to be trying to say that glacier melting isn't a sign of temperature warmings, but actually temperature rise is symptom of increased surface radiation. Might not that have something to do with the ice melt.
  15. Roy Spencer's Bad Economics
    jzk - I agree that China and India need to expand energy production but poverty-stricken countries are also most vulnerable to climate change. For this reason, the West has to reduce CO2 consumption and do it very hard. You can encourage non-carbon energy generation in other countries by whacking a carbon tax on incoming goods at the border - just as an example. Good luck getting China and India on board if the West - responsible for most of the extra CO2 in the atmosphere - arent willing to make major reductions.
  16. New research from last week 10/2012
    Flakmeister - Which paper, which Solheim? Note that there is a JE Solheim who frequently works with Dr. O. Humlum, whose papers have been roundly criticized and refuted.
  17. New research from last week 10/2012
    Whats with this Solheim paper making the rounds??? I did a quick perusal and it strikes me as mathurbation combined with perhaps cherry picking the data... Why did they not apply it to the whole globe???
  18. Glaciers are growing
    Henry justice @20, you are assuming that Otzi died in an ice free area that later became glaciated. That would be near impossible, and is contrary to the evidence. Rather, he died above the permanent snowline, and has remained above the permanent snowline ever since.
  19. Lindzen's London Illusions
    jzk - he didn't ignore the ice melt, but he sure did do his damndest to make it look small (Figure 2 in the post above).
  20. Lindzen's London Illusions
    jzk @68, "Going through each year of the Arctic daily mean temperatures seems to bolster Lindzen's point that the summer temperatures are not changing while there is great variability in the winter temperatures." I find it incredulous that someone is defending Lindzen, especially when they appear to not grasp the obvious problems with his argument. First, those data are for 80 N, they are not representative of the Arctic. Second, they are model data and it has been shown that the ERA_40 data that he is showing have problems with the temperature. Third, the theory and scientific literature on Arctic amplification is very clear that the impacts of the ice loss should be and are felt primarily in between the fall and spring, with impacts that carry over into the next melt season. For exanple, Screen and Simmonds (2010), "The Arctic region has long been expected to warm strongly as a result of anthropogenic climate change owing to positive feedbacks in the Arctic climate system." Also, the reason that the warming is less during the short summer (note, not absent as Lindzen claims) is because there are changes in radiative frocing b/c of changes in cloud cover. Again fro Screen and Simmonds, "In the Arctic, this greenhouse effect dominates during autumn, winter and spring (Fig. 3), in agreement with in situ observations. In summer, the shading effect dominates in the lower-latitude regions of the Arctic basin whereas north of 80 N the two competing effects approximately cancel out (Fig. 3c)." So Lindzen's entire premise is wrong. Lindzen is also not providing his audience with a complete picture, nor is he providing any caveats as a good scientists should do. Additonally, research has shown that the length of the melt season is increasing significantly, see here. All these data and facts fly in the face of Lindzen's claims.Lindzen is playing games and doing his best to mislead people-- sadly that seems quite easy to do.
  21. Henry justice at 07:00 AM on 15 March 2012
    Glaciers are growing
    oneiota: Glaciers may or may not be a good indicator of climate change. Uniform melting of mountain glaciers, excluding Greenland and Antarctica, is an indicator. About 65% of all mountain glacial ice worldwide as noted above, is found in Canada. So, if Canadian glaciers are all melting, in unison,then, yes, a good indicator of global warming. It is my understanding that Mt Kilimanjaro's source of moisture for glacier building was a forest at its base, which had been cut down, so the glacier disappeared. Many glaciers have sublimated even when the temperature above the glacier was still below freezing. Can someone vouch for the temps over each of these declining glaciers? That data appears missing? So, the many causes for glacial decline are not even mentioned.
  22. Lindzen's London Illusions
    Sphaerica@74, If all that is true, you ought to be able to calmly dissect his arguments. Going through each year of the data, it sure does seem to me that his premise is true. Summer temperatures don't seem to be changing while there is much variability in the winter temperatures. He didn't ignore the ice melt, nor any of the temperatures. His conclusion that because summer radiative forcing doesn't seem to be changing CO2 must not be a factor is subject to debate. However, nothing in your post @74 adds any clarity to this.
  23. Henry justice at 06:42 AM on 15 March 2012
    Glaciers are growing
    muoncounter:The finding of the ice mummy, Otzi, does this indicate the present melting of the glaciers are now back to the level where they were when this mummy was first frozen? So, this would represent natural climate variability.
  24. Roy Spencer's Bad Economics
    jzk: The physics quite clearly shows that action to reduce CO2 emissions must be taken, contra Roy Spencer's claims. The economics quite clearly show that (a) based on the current and expected costs of climate disruptions, action to reduce CO2 emissions must be taken and (b) such action will not cause economic harm to polities which undertake it, again contra the claims of Dr Spencer. The ethics of the situation (following from the disproportionate burden of climate change impacts) quite clearly show that "old rich" countries have an obligation to take the lead in reducing emissions (and as Rob noted, emissions in developing economies are often "outsourced" developed-world emissions) - yet again, contra the claims of Dr Spencer. Developing countries are designing & implementing their own emissions control regimes, so they will catch up. When there is a consilience of imperatives for action, endorsement by several bodies of relevant experts, and the means to track national emissions - which you acknowledge given you cite them in #22 - then there is both the obligation to proceed with emissions reductions, and the practical means of showing who is undertaking them and how effective they are.
  25. Lindzen's London Illusions
    jzk, Come on. How stupid do you think people are? Implying that summer temperatures are not changing, while ignoring the rapid, growing ice melt, is cherry picking. Suggesting that the false dichotomy of summer versus winter temperatures is all that applies is pathetic. His entire position is pathetic, as are all of his presentations and arguments. Lindzen is a joke, a bad one, and history will not treat him kindly, if it remembers him at all (which it should).
  26. 2012 SkS Weekly Digest #10
    Trent1492 - my humble apologies. I see your point and I agree that the tone of my response was completely inappropriate. It was a knee-jerk reaction without really properly at the context.

    Roy Spencer's Bad Economics
    jzk... I'm certainly not an expert on the matter. I know what I've seen, which I believe is probably a tiny snapshot of the overall picture. But my observations are this... First, I'd say farmers in rural China are living pretty much as they have for many hundreds of years, at least. The region I visited was central China, outside of Chongqing, where my wife is from. The home we visited was similar to this. It was a multi-family home. The first floor rooms were all only three walls. No heating. These were the living and dining areas. I don't remember off hand if they had electricity. I think they did not. A side room on the first floor was a kitchen with two extra large woks for cooking. Fuel for cooking was coal. The surrounding farm was very well kept. They were very proud of the quality of their produce and we had fun going out into the gardens with the kids to help pick some of the food that was cooked. The people are very cheerful and happy, but I don't think it's lost on them that they are poor. They're clearly not suffering like poor people in other regions. But they've seen what other family members have achieved in moving to the cities and, I suppose, some are inclined to such aspirations and others are inclined to remain with the lifestyle they've always known. My wife and I have been married 10 years and she's very open to discussing the good, the bad and the ugly. I don't hear horror stories about factions of the family that live on the farms. I hear more horror stories about dealing with small town government officials who make it impossible for anyone to accomplish anything. The larger cities are more reasonable with respect to that. I know the government is intent on getting more people off the farms and into urban housing. I don't know any stories of this happening forcibly. I hear stories about farmers who do sell their leases back to the government (there is no private ownership, just renewable leases) and make a pot of money. They often have a hard time coping with the change.
  28. Roy Spencer's Bad Economics
    bill@2 One example of a left-wing climate denier is Claude Allègre who is a scientist, is a member of France's Socialist party, was Minister of Education from 1997-2000 in Lionel Jospin's cabinet and is probably the most prominent climate "skeptic" in France. He was debunked by RealClimate in 2010. Allègre his fellow fellow-traveller, Vincent Courtillot, were debunked in 2007, again in RealClimate. Both Courtillot and Allègre are, in their field--ahem, geology--genuinely distinguished scientists and they are both still active. I attended a talk given by Allègre at the 2011 AGU Fall Meeting and spotted Courtillot in the audience.
  29. Lindzen's London Illusions
    Sphaerica@72, Cherry picking is when favorable evidence is chosen while unfavorable evidence is excluded. Which evidence was excluded? I recall him discussing both the summer and winter temperatures.
  30. Lindzen's London Illusions
    70, jzk, My point is that focusing on summer temperatures in the Arctic, while the ice is clearly melting further and further back each year, is disingenuous. His statement is one of misdirection with no merit. A discussion of summer temperatures is a cherry pick designed to mislead. There are many factors that affect summer temperatures, not the least of which is that melting the ice, a huge danger, is helping to hold those temperatures down.

    Declining Arctic sea-ice and record U.S. and European snowfalls: are they linked?
    My opinion on solar cycles has changed a bit over time- I always thought that low solar would affect weather more than climate, but there are many influences in different directions even for weather, never mind climate. Anyways, it is OT for this thread. The sea ice influence is quite weak IMO and won't do much to influence weather patterns compared to other factors. The more obvious connection is that the weather patterns dictate where the sea ice gets melted and where it gets compacted (usually the same areas). This year that was the Barents sea. Although the warm anomaly could essentially have created a high to pull cold air down into Eastern Europe, it is more likely that other effects caused the pattern of the high which warmed the Barents sea and pulled cold air into eastern Europe.

  33. Rob Honeycutt at 04:39 AM on 15 March 2012
    Roy Spencer's Bad Economics
    Bruce and jzk @ 19 and 22... I always like to point out that a large portion of China's per capita carbon emissions are the result of being, essentially, as "factory state." They're mostly making products for western consumption. Around two thirds of Chinese are still living an agrarian lifestyle. (I had the wonderful opportunity once to attend a rural Chinese wedding and see how farming was done and see the setting in which these people live.) There are a certain fraction of Chinese who have attained US style first world status and I'm sure their personal carbon emissions are similar to anyone in the west. It's just not the case for most middle class Chinese. I hold that a large portion of those per capita Chinese emissions should be assigned to the west since they are primary a result of us "out sourcing" our carbon emissions. Apologies for veering off topic.
  34. Declining Arctic sea-ice and record U.S. and European snowfalls: are they linked?
    True that there is some merit to it (Lockwood, etc), but this winter, the AO went very negative for a while, despite the much higher solar activity than the two previous winters. Interestingly, the NAO stayed positive when the AO went negative. They are normally closely linked. The deniers long tem forecast for the coming years is strong cooling due to the proposed weak solar cycle, but when we break the global temp record in either 2013 or 2014, they will explain that by pointing to high solar activity. They can do this because the press rarely points out their failed predictions. When 2010 broke the record, hardly anyone asked for an explanation for the failed denier predictions from 2008 of rapid cooling from that year.
  35. Roy Spencer's Bad Economics
    Bruce@19, For 2010, China's CO2 emissions per capita were 6.8 tons, and the US was 16.9. The amounts are not as important, however, as the trend. I suspect that 2011 will come in 10% higher than 2010. Total output for China was 8.94 billion metric tons, and US 5.25. And, India hasn't even gotten started yet relatively speaking, as they are only at 1.5 tons per person.
  36. Roy Spencer's Bad Economics
    I suspect that the essential difference between those people complaining that green measures will harm the economy and those who advocate action to limit emissions, is simply one of mind set. The 'business-as-usual' crowd are pre-conditioned to think short-term and will say that either something will come along to fix our problems (because something always has), or that we should let future generations look after themselves (like they always have). On the other hand those seeking to limit emissions are cautious (dare I say conservative?) and prepared to make short-term sacrifices for long term benefits. I'm convinced that essentially there are ways that the brain is wired (or programmed) that distinguishes these two personality types. Of course, confusing the issue, is the fact that there are also minorities on both sides who don't really care about the functioning of our biosphere but see the global warming issue as providing a focus to latch onto in pursuit of their personal ideologiocal agendas.
  37. Roy Spencer's Bad Economics
    thanks Paul D (re #9), I've had a look at some of Graham Stringer's statements re "climategate" and he does seem tediously ill-informed and way-over-the-top belligerent about this. ...how tedious...
  38. Roy Spencer's Bad Economics
    Jzk, although China's per capita co2 emissions are increasing , current rates at 5-6 tons per person are far below U.S. Or Australian rates at 17 tons per person.
  39. Roy Spencer's Bad Economics
    John Brookes @10 - yes, the 'CO2 limits will harm the poor' argument seems to be a favorite of Christy (who spent some time in Africa) and Spencer. Since they're 'skeptics' that CO2 will have much impact on climate, I suppose they have plausible deniability to the fact that they're actually advocating a path that will harm those same poor. jzk - as noted in the OP, the USA is most responsible for overall CO2 emissions, and thus is (or at least has been) expected to take a lead role in reducing them. The Chinese in particular have expressed concern about climate change, but you certainly can't blame them for waiting on the USA to take the lead considering our much larger proportion of historical emissions. Yes, we need China and India on board, but they will be. The problem is that the train isn't even ready to leave the station.

    "Why does it matter?" Because without the developing countries on board, you won't be able to measure the difference that will result from a CO2 emissions cut. So then, it depends on your goal in implementing the policy. Is it a symbolic gesture? A "punishment" for past emissions? Or is it a policy that will have a measurable result? It is a practical problem that doesn't depend on one's ideology. Appealing to economic authority doesn't make that practical problem any less of a problem.

    About particulates/wind etc...I live in Salt Lake (the little red spot out in the intermountain west in the map!) where we oftentimes have auto/industry pollution trapped in our mountain valley. The wind comes from the West/SouthWest (where it is desert-think Salt Flats). Rarely we get a sandstorm that raises particulates (more often PM 10 than PM 2.5). More often we pray for wind to clear out the valley of our absolutely manmade particulates... As for the Eastern US, those "red zones" sure ain't coming from desert dust storms, but from all the coal plants out there (note scale difference in Red from World Map in OP).

    Declining Arctic sea-ice and record U.S. and European snowfalls: are they linked?
    The "low solar" explanation has substance considering that the stratospheric influences are largely seasonal. Low solar, particularly low solar ultraviolet, has a strong influence on the stratosphere by inducing uneven cooling. In winter the decreased contrast in troposphere to stratosphere allows greater wave penetration so stratospheric waves can impact tropospheric waves and vice versa so that uneven stratospheric temperatures are more likely to result in negative AO. Over the next century however, the main influence of greenhouse gases will be to warm the troposphere, cool the stratosphere and reduce the influences of uneven stratospheric warming on tropospheric weather. The AO has been predicted to become more positive and winters like our past winter here in North America (very warm due to largely positive AO) will become more common. There are somewhat alternative explanations to the OP and the papers referenced in it. One is here: http://journals.ametsoc.org/doi/pdf/10.1175/JCLI3530.1 (The NAO, the AO, and Global Warming: How Closely Related? by Judah Cohen and Mathew Barlow) where they say:
    For example, they suggest that greenhouse gases cool the stratospheric polar regions relative to midlatitudes and the Tropics, refracting propagating tropospheric planetary waves equatorward, resulting in a positive AO. However, it is possible that greenhouse gases might cool the midlatitudes and Tropics relative to the polar regions, therefore refracting planetary waves poleward and favoring a negative AO.
    I also like their explanation of the negative AO, a bit of a twist on the OP above, that the open waters caused more early winter Siberian snowfall which then caused negative AO which occasionally results in lower latitude snowstorms but those are mostly weather flukes.

    And that is why they are doing so. No matter what the west does, China and India will soon surpass the west in CO2 output per capita. That's nice. Why does it matter? As has already been shown in the OP, a majority of US economists with knowledge of climate economics suggest US CO2 emissions should be cut without any regard for what other countries are doing. Are you suggesting that countries who have contributed to the vast majority of past CO2 emissions and who continue to contribute to a large portion of present emissions should wait for India & China to start cutting emissions?

    Re: Far Left Wasn't Martin Durkin, director of Great Global Warming Swindle, (self?) cast as a socialist? On SkS there was a long time poster called "HumanityRules" who proclaimed a socialist viewpoint whilst having denier tendancies. Perhaps the hijacking of the AGW denialism by the free marketters was made it less appealing to the far left now ?

    Ironically the current level of poverty is precisely what's giving us a bit of extra time to deal with the issue of climate change. If the billion or so people living in conditions of extreme poverty were actually energy-demanding consumers things would probably be out of control already. Cold comfort to them though. Regarding the prevalence of libertarian views among deniers, one needs to look no further than the inhabitants of Nova's blog. It's all fiat money conspiracy and free market nonsense.

    I disagree as well, jatufin. It's not a planet. Ron Paul enthusiasts do share some of the same policy positions as some on the "far" left (is "near" the "right" place to be, then?). However, the reasons for those positions are diametrically opposed. Real world socialism encounters environmentalism in the same way that religious conservatives do: it's the right thing to do, but life under capitalism limits choice. It's an easier choice for university professors (including the academic left) and managerial class folk, but capitalism doesn't result in a class structure comprised of an overwhelmingly large middle class (regardless of typical middle class representations of the world). Most of the consuming world is made of people who live day to day, week to week, or month to month, hoping for a break, accepting their lot in life, or fighting to get the rest of their compensation (the working left). These people are not operating on a level field. Their representatives are not operating on a level field. The core mechanism of capitalism works to concentrate economic power (real power) into the hands of the few, and economy trumps democracy all day long. Economy trumps all, no matter the mode. Environmentalism is simply the higher-order realization that most economic modes (capitalism very much so) are short-sighted with regards to the relationship between resources and economic growth. Environmentalism is the alternator to the engine of economy. Take it away, and your engine runs with a little less drag, but then all you have left is a battery. Those in the trenches of class warfare don't have much time to think about the charge left in the battery. The owners of the means of production certainly do, as do the managerial classes whose comfortable lives are ensured by continued protection of property owners' interests. Yet, when faced with the scientific revelation that the battery is running out of charge, these folk go into denial (well, publicly anyway). Why? Why would an information manager like Jeff Condon seek to limit or cast doubt on the information that his ethics "chip" has access to? That is the bizarre condition of those on the economic right in the managerial classes, but it is a condition that they share with the religious right: living one's life according to the interests of one's master(s) allows a kind of freedom--the freedom to act with absolute certainty that one is doing the right thing and that it will always be (always will have been) the right thing. Quite different from the OS of the dialectal left, for whom life is a series of shifting probabilities, shifting as the evidence is compiled each minute, each day. If you want the mid-left on environmentalism, here's a shot. I'd like to get Ian to do a guest post on AGW and the left.

    John Brookes@10, For anyone really interested in reductions of global CO2 emissions, solving the poverty issue is your main, and most problematic hurdle. China and India know that the fastest way to bring their people out of poverty is to build coal power plants as fast as they can. And that is why they are doing so. No matter what the west does, China and India will soon surpass the west in CO2 output per capita. "Leading the way" makes for a nice, costly symbolic gesture, but if you can't get India and China on board, the results will be difficult to measure. Poverty in Africa and Asia is not a result of attempts to limit CO2 emissions. It is because they don't have access to cheap power, yet. 20% of the world's population has no electricity. These areas have little access to clean water and very poor agriculture. How do you solve that without increasing CO2 output? How do you get China and India to stop increasing CO2 output?

    A particular annoying theme of climate "skeptics" is their faux concern for the poor. They argue that any attempts to limit CO2 emissions will condemn the poor of Africa and Asia to eternal poverty. I have a suspicion that there are much more relevant reasons for poverty than attempts to limit CO2 emissions.
