       A Detailed Look at Renewable Baseload Energy
       BBD @104, yesterday I commented that

       "That post [your 69] contained some good advise by Hansen, and a stack of numbers use to build up emotional weight, but no analysis."

       (emphasis added) I made that comment half an hour before you asked me to comment on Hansen. But seeing you have asked:

       "Energy efficiency, renewable energies, and an improved grid deserve priority and there is a hope that they could provide all of our electric power requirements. However, the greatest threat to the planet may be the potential gap between that presumption (100% “soft” energy) and reality, with the gap filled by continued use of coal-fired power. Therefore it is important to undertake urgent focused R&D programs in both next generation nuclear power and carbon capture and sequestration. These programs could be carried out most rapidly and effectively in full cooperation with China and/or India, and other countries. Given appropriate priority and resources, the option of secure, low-waste 4th generation nuclear power (see below) could be available within a decade. If, by then, wind, solar, other renewables, and an improved grid prove that they are capable of handling all of our electrical energy needs, then there may be no need to construct nuclear plants in the United States. Many energy experts consider an all-renewable scenario to be implausible in the time-frame when coal emissions must be phased out, but it is not necessary to debate that matter. However, it would be exceedingly dangerous to make the presumption today that we will soon have all-renewable electric power. Also it would be inappropriate to impose a similar presumption on China and India. Both countries project large increases in their energy needs, both countries have highly polluted atmospheres primarily due to excessive coal use, and both countries stand to suffer inordinately if global climate change continues."

       (my highlighting) I still think the letter contains good sense - all of it. But I have to wonder, seeing you have introduced Hansen as an authority why you are ignoring those sections that I have highlighted? Why the bitter and unenlightening attack on renewables? You asked in your 81 if I am "a little anti-nuclear"? Well, not especially. I am cautious about nuclear, and have been unable to get satisfying answers from nuke boosters on key issues. But my immediate response to Fukushima was to post a comment on this site to the effect that it changed nothing, and that specifically AGW was so great a threat that nukes cannot be taken of the table. What disturbs me most about Fukushima was not the accident itself, nor the level the disaster has currently reached. These are, in the end, engineering issues, and engineering issues are solvable, at a price. It was the blaisé assumption that things would not get worse, and the jokes about the radiation levels in bananas. It is the same nonchalant attitude to safety that caused the problems at Fukushima in the first place, and which you exhibit in your responses regarding the risks of terrorists capturing a nuclear power station.

       We can only wish Wegman would be subjected to such diligent inquiry by his employing institution. As for McIntyre, he's not at risk, no institution employs him, so who will conduct an official investigation? It's good to be a skeptic; all the glory, none of the responsibility...

       A Detailed Look at Renewable Baseload Energy
       BBD @101: From 101: a) 64.6 trillion kWh of electricity produced by nuclear; b) 2 INES 7 events; Therefore, c) 1 INES 7 event per 32.3 trillion kWh produced by nuclear; From 69: d) 11.5 Terrawatts of clean energy capacity required; Or e) 100 trillion kWh of electricity if produced at peak capacity; Or 50 trillion kWh of electricity allowing for a peak to zero capacity cycle everyday; So F) An expected 1.5 IES 7 events per annum if fossil fuels are replaced by nuclear at current safety standards. But not to worry, the nuke boosters assure us the latest model reactors are much safer. And they have such a good track record of assessing risks:

       "2. No, quite the opposite. They have just performed robustly in the face of the worst earthquake ever to strike the Japanese islands. The risk of meltdown is extremely small, and the death toll from any such accident, even if it occurred, will be zero. There will be no breach of containment and no release of radioactivity beyond, at the very most, some venting of mildly radioactive steam to relieve pressure. Those spreading FUD at the moment will be the ones left with egg on their faces."

       (Barry Brook commenting on Fukushima, March 12, 2011) Again you are throwing up a wall of numbers without carrying it through to an actual analysis, just as you did on your first full post on the topic. And with regard to those numbers (and your comment @103), I don't care whose numbers they where, you quoted them, and you drew an implication from them. Therefore either you defend them, or you withdraw the implication. You do not get to both disavow the "evidence" and retain it as bolstering your argument, at least not if your purpose is rational discussion or analysis rather than propaganda.

       Camburn: Why are you on this thread? This thread is about the economic benefit of mitigating climate change - not at the level of catastrophe avoided, but at the level of ingenuity rewarded. In post 32, point 4 you express deep confusion about the physics of climate change. Please go to the myriad of threads on this very site that explain this and understand the basic issue. Once you understand why the CO2 doubling will lead to 2C or more temperature increase, we can start with you on equal footing with the rest of us. It isn't fair to the rest of us that you bring your confusion to this thread. You could start by understanding how, if it is 1C MAX, and we haven't even doubled yet, that we are at .8C increase. Something doesn't square in your physics and/or logic. Your points have very little merit given that you don't understand the basis of the discussion. PS - your points regarding the Republican debt are consistent with your understanding of climate change - muddled and mostly wrong. But I don't find any thread on Skeptical Science appropriate for discussing them. Suffice it to say you are wrong on that issue as well.

       A Detailed Look at Renewable Baseload Energy
       BBD : "You don't 'like' nuclear, but I don't believe renewables can even come close to the potential for displacing coal." Who told you that I don't like nuclear ? I believe it is an old, dirty and dangerous way of producing energy and that we should move as quickly as possible to renewable sources, but that doesn't mean that I don't think it shouldn't be used now, where there are no other options. It should only be a last resort, though, and only as a temporary stop-gap before renewables take over. I don't, however, like nuclear power evangelicals, who are prepared to lessen the dangers and constantly see the best - as the UK government and Brave New Climate did, literally days after the accident. That is called wishful, blinkered thinking. What you believe about the potential for renewables is just that, though - your belief. BBD : "You might want to ponder what a widespread and prolonged failure of the European supergrid might look like. How many fatalities would you expect?" I have no idea. Perhaps you have a number you can believe in ? BBD : "I had a feeling someone would bring up the news from Japan." Sorry to bring up uncomfortable news. That is life that cannot be swept under the carpet or PR'd away. BBD : "However, your anti-nuclear sniping requires an answer" Not being anti-nuclear, I can only assume that what you call anti-nuclear (without any evidence) is actually anti-nuclear evangelism. Guilty. BBD : "But nuclear has been around for longer than you might think." So why does it still need to be subsidised and secretly pushed by governments ? Can't it stand on its own feet and pay for itself yet ? How long more does it need before it can do that ? BBD : "Yet since the vast majority of reactors came on line in the last 40 years, there have been 18 incidents that merited a rating on the International Nuclear Events Scale (INES). It is important to remember that in operational terms, this is 18 incidents in 11,255 years." Very safe indeed but how many industries can you think of which require long-term evacuations from large areas, as well as intensive and expensive clear-ups, after an accident ? How do you think it feels to have survived a natural disaster, only to be told that you cannot live your life in some form of normality afterwards because a power source miles away means it is unsafe for you to return to your home ? BBD : "Anyone who says that the anti-nuclear lobby should not be allowed to make comparisons with Chernobyl is absolutely correct. It is a grotesque misrepresentation. There have been no fatalities and none are currently expected. In other words, such contamination as may have occurred is likely to be minor and transient." Something about your confident predictions of future non-deaths and minor inconvenience is very troubling and, again, marks you out as a nuclear evangelist. There is a very simple comparison with Chernobyl, though you may wish to lessen it : both were maximum Level 7 severity, involving a major release of radiation with widespread health and environmental effects. The fact that you try to lessen the seriousness, speaks volumes.

       batvette wrote : JMurphy, is this statement disinformation or false? "Michael Mann's conduct was examined by an internal, not independent, review board of the entity which employed him and stood to lose credibility if it were revealed he acted improperly." This is what I've been saying, it's all that I'm saying, (on that matter) and if you are going to accuse me of "purveying disinformation" please specify what about it is. It's very simple : The guidelines for such an investigation - acceptable to be used for any other individual except Dr Mann, according to the so-called skeptics, it would appear - are : The Committee shall consist of at least five tenured University faculty members, each of whom should have no conflict of interest and be competent, in the judgment of the Vice President for Research, to evaluate the questions before the Committee. In this case, the individuals involved came from the Departments of Biology, Chemistry and Physics, Computer Science and Electrical Engineering, Anthropology, and Human Development and Family Studies. Again, unbiased enough for any individual except Dr Mann, presumably. Ultimately, if Dr Mann had acted improperly, and it could be proved that he had, the university would have been more than keen to ensure that punishment would have been swift and proportional - if only to preserve the integrity and professionalism of the university itself. The fact that it found no such thing, due to the distinct lack of any form of evidence in the real world, still smarts with the so-called skeptics. Less of the disinformation and more of the facts, please.

       Google It - Clean Energy is Good for the Economy
       Camburn @36, if you accept that "economics works", you would also accept that large, uncosted negative externalities distort the market and reduce overall wealth. Such uncosted negative externalities would therefore be anathema to you, and you would be looking for the most efficient means to either place a price on the externalities, regulate it out of existence, or ensure a payment from the producer of the externalities to those suffering its effects. In the case of GHG emissions, the most effective way to do that may be to introduce a carbon tax either with a dividend to end users on some basis (and there are different ways of paying the dividend), or subsidy to low carbon energy producers. It may be a cap and trade scheme. It may be a legal requirement for carbon emitters to fund expected payouts for damages arising from loss of habitat, and health effects from global warming going forward. But not doing it is not assuming that economics works, but that it doesn't.

       Google It - Clean Energy is Good for the Economy
       actually thoughtful@31: Mr. Hansen has made predictions concering sea levels in the past that have not born out. 2. This is not a Republican "deficit". This is a mutual one. The tax cuts of 2001 and 2003 were idiotic, but that is not the crux of what you said. I understand that you limited your comment to the constraints of a budget. SS is not included in the budget. When you add the increased funding required for SS and Medicare, even allowing the physician increase to lapse, the financial health will not correct itself by 2014. The rate of rise in the debt will slightly slow from present levels, but it will certainly not lessen. This is also from CBO. 3. The free market is already harnessed to decrease energy consumption, and it has started. As energy prices rise, you will see an excalation in this trend. 4. Co2 is a greenhouse gas, the physics show approx 1.0 for a doubling of co2. I am in no way convinced that the temp rise will be 3.0-6.0C.; hence I am not concerned about long term effects. I am concerned about current economic distress which is becoming more apparant all the time. Point #7. In order for the US to service just the interest on its current debt, with spending projections from CBO used, will require a tax increase of 6-8%. Add another tax on top of this debt service will stiffle economic growth. The free economy is much better at inovation/invention than the government is. Concerning medicare. When I was inocculated it cost my parents $5.50. When I broke my arm, two days in hospital, xrays etc.....total cost was 114.76. My father still has the bill. Older folks who are now recieving medicare at current tax rates are exceeding the revenue stream. To substain that care, taxes are going to have to go up. Health insurance is a pool and off topic. We can debate that one at another time.

       Camburn @26 Your points # 1 is easily disproved by looking around this site. Please do so. Hansen says BAU could produce over 2 meters of sea level rise this century. Point # 2 is mostly useless in this debate because the debt is a Republican issue, not a real issue. If we wanted to eliminate the national deficit in the USA - we just have to do nothing. The law calls for the end of the Bush era tax cuts, and the end of all the Medicare "Doc fixes" - these two things alone would end the deficit by 2014 (according to the CBO). Also, this post talks about the economic increase that accelerating the switch to renewables will bring. Economic growth will reduce the deficit, assuming spending is limited or reduced (which certainly appears to be the case) Your point # 3 is exactly the point - adding a carbon tax will harness the free market to mitigate climate change risk. You are presenting arguments for my perspective. Thank you. # 4 is, AGAIN, exactly the point! If we don't handle climate change and soon, "the economic distress will cause enormous human distress that will result in wars, famine, etc." We don't need to fix health care right now, we don't need to fix the deficit right now - we do need to fix our relationship with the environment, from where all wealth comes from. Thus the push for a carbon tax. Points 5&6 indicate a willingness to set the bar too low. Sure, we are seeing a small, slow growth in renewables. But compared to the overall energy puzzle, renewables are too small, and the current trend (BAU) leads to the planet shifting into a mode that is hostile to happy humans. Point # 7 is counter to the evidence presented in this post. It is counter to our experience with the ozone layer and with acid rain. What is your evidence (not ideology) to support this claim? Everything we know tells us the opposite is true - that a carbon tax will spur an economic boom by setting the conditions for economic expansion as we switch from carbon based to renewable based energy. It is interesting to me, given how well you understand things at point # 3 & 4, how your conclusions don't follow. You point out that government involvement in Medicare causes increased costs and poor execution. Where are the millions of seniors rising up demanding changes to Medicare? Oh, wait. Those millions of seniors are demanding NO changes to Medicare. OK - well what about the worldwide consensus that the US military is a paper tiger, and easily defeated? Oh, wait - the US military is the most respected fighting force in the world. So two of the largest programs the US government undertakes are incredibly effective, and whether they would be cheaper in the private sector is somewhat debatable, but I notice the private sector is not doing very well in these two area (Blackwater as one example in the military space -we know how effective they are, and health insurance - the most beloved industry in America... NOT). So, as near as I can tell, your conclusions don't follow from the evidence you presented, and are demonstrably false to boot. Care to try again?

       The Planetary Greenhouse Engine Revisited
       And if, at the same frequency, the tropopause and mesopause can both emit radiation, the would also absorb each other's radiation, to the extent the intervening space is transparent (which it isn't!) and to the extent they can emit (relative to the Planck function). Of course the whole upper atmosphere is nearly transparent over some spectral bands, over a broader interval than the 'atmospheric window' and more transparent than the 'atmospheric window'. (the atmospheric window, roughly 8 to 12 microns (interupted by ozone somewhere around 9 or 10 microns) is a band where a sizable fraction of radiation from the surface can reach space, absent clouds or high humidity levels. Aside from ozone, Most of the non-cloud opacity in the atmospheric window comes from water vapor and most of that is in the lower troposphere) But there isn't a particularly greater abundance of greenhouse gases near the tropopause or mesopause than in between (in fact ozone has a maximum in between), so at wavelengths where emission from the regions of the tropopause or mesopause is significant (relative to the layer thickness, which is extremely small for anything above the stratosphere), so would be emission and absorption from the intervening layer.

       Throwing Down The Gauntlet
       Actually Thoughtful@18: I have made a suggestion in another thread that to take action does not require even talking about climate. 1. Base action on economics. We know that coal/oil/gas etc are finite. We know that in an expanding world energy use will continue to rise as that raises the standard of living. 2. We know that energy costs are going up. That premiss is born from pricing facts and is indisputeable. 3. We know the reason they are going up. Inelastic demand as well as inelastic supply. 4. The way to address the supply side is with another source of energy. 5. Given demand curves, given supply curves are easy to observe with the naked eye, and are indisputeable. The above items are well known. Rather than focus on an elastic sensativity, focus on the inelastic reality. It would be a very easily sold concept in the USA where the population as a whole is well educated. It will take leadership, of which the USA seems to be short on at this time. China is a different story. The Chinese have money, they are building 2 new coal fired power plants every week. India is not far behind. The environmental record of both of those nations is certainly not something to be proud off. To get the Chinese and Indian people to stop consuming coal at the present rate of increase is going to be extremely difficult. Rather than focus on co2, I still suggest focusing on finite resources, and the way to overcome the disadvantage of consuming these.

       A Detailed Look at Renewable Baseload Energy
       I think 20% is at the low end of the likely renewable contribution by 2050. I suspect it'll be closer to 50%. Most of the rest will probably be natural gas and nuclear. Hopefully you're right about Gen III reactors. Looks like China is building a few. Time is still an issue, with at least 5 years of construction, and a number of years of planning before that. People may delay construction of certain renewable projects, but they generally support the technologies. That's a problem for nuclear power. Wind turbines have very little land impact - the ground between turbines can be used for other purposes. Solar can be placed in deserts and on rooftops. Wind turbines can also go offshore. And so on and so forth. Renewable land impact really isn't a concern. You'll get a few whiners complaining about individual projects, but not enough to make a significant difference. But a lot of people have major concerns about nuclear power. I'm not saying they're necessarily justified - many aren't. But that's the reality of the situation, as long as we're talking about practicality :-)

       Norman @208, "I am not debating the issue if the planet is warming" Good, but you miraculously manage still miss the point entirely...it was an analogy. "You need to prove that a warmer world will lead to more storms or floods or droughts by at least providing a mechanism on what a warmer world will effect." Strictly speaking one cannot prove anything in science. That is just how it is. Now, I am going to spend some time with my family.

       dana1981 I agree that there's no silver bullet. I agree that renewables will play a substantially increased role in the global energy mix - perhaps even as much as 20% by 2050. Which leaves 80% on the table. Which I think was Dr Hansen's point. I disagree that Generation III nuclear plant will be problematic in terms of cost or construction rate. I agree that there will be public opposition to new nuclear, which is why anti-nuclear lobbying is so dangerous from a climate perspective. I would like you to consider why you ignore the certain public opposition to the enormous environmental and landscape impact from the footprint of even a 20% renewables contribution to the global energy mix. I agree that we will build smarter grid infrastructure and increase energy efficiency (and applaud that thought). I am concerned about your last paragraph. You do not seem to have absorbed much of what has been said above, eg 96, 98, 99.

       The Planetary Greenhouse Engine Revisited
       Holton (1992), p. 405, (in contrast to/with the troposphere): "In the stratosphere, on the other hand, infrared radiative cooling is in the mean balanced primarily by radiative heating owing to the absorption of solar ultraviolet radiation by ozone. As a result of the solar heating in the ozone layer, the mean temperature in the stratosphere increases with height to a maximum at the stratopause near 50 km. Above the stratopause temperature decreases with height owing to the reduced solar heating of ozone." p.404, the troposphere: "Because very little solar radiation is absorbed in the troposphere, the thermal structure of the troposphere is maintained by an approximate balance among infrared radiative cooling, vertical transport of sensible and latent heat away from the surface by small-scale eddies, and large-scale heat transport by synoptic-scale eddies. The net result is a mean temperature structure in which the surface temperature has its maximum in the equatorial region and decreases toward both the winter and summer poles. There is also a rapid decrease in altitude with a lapse rate of about 6[K/km]." I should add that you can account for the solar heating of the air simply by using net radiant cooling (net LW cooling minus solar heating). And the small solar heating of the troposphere is in terms of K/day, or heating rate relative to mass. In terms of the total flux, solar heating of the troposphere is considerably larger than that of the rest of the atmosphere. The solar heating in K/day is smaller in the lowest part of the stratosphere than it is in the troposphere, but gets larger going into the upper stratosphere (Hartmann).

       2010 - 2011: Earth's most extreme weather since 1816?
       Albatros @ 207. Maybe we are not connecting in points because from this post it seems you and I are not discussing the same issue. "My point is that one can always seek out locations or times when the data appear to go against the long-term upward trend in temperatures. But to use those data to conclude that the warming is either not happening or not significant is both wrong and misses the point altogether. And seeking out such data is not viewing the body of evidence, but is rather an elaborate form of cherry-picking and argumentum ad absurdum, something that you and both the NIPCC have both identified, perhaps even independently." I am not debating the issue if the planet is warming and that cause is mankind's abundant release of this gas via burning carbon based fuel. That would be "denier" as defined (closed mind) since the facts are obvious that man is burning, collectively, large amounts of carbon based fuel and it is proven empirically that atmospheric CO2 will absrob and redirect IR radiation omnidirectonal so that some will return to earth at the CO2 molecular resonance modes. I am only questioning the collection of severe weather events of 2010 and using this as proof that the warming globe is causing an increase in extreme weather that have caused more destruction and will continue to get worse as the planet continues to warm. We are on two different topics. I do not know if global warming is or is not increasing the intensity, duration or frequency of severe weather events capable of causing disasters that kill people and destroy property. There are vast amounts of articles claiming it is a fact. When I do searches for evidence to determine if this is true, many state it is true but very few provide any proof. A general concept that a warmer world with more moisture in the atmophere would automatically lead to more storms is not good science from my understanding of it. You need to prove that a warmer world will lead to more storms or floods or droughts by at least providing a mechanism on what a warmer world will effect. How will it alter the jet stream? It may shift it poleward but will that create more intense dangerous storms? It certainly may but I would like to see an explanation of how it would produce more storms, what will it do to cause the increase? That is what I am spending time on this site and others questioning. Just saying the events of 2010 are the result of a warmer/wetter world without any challenge nor a need to provide more detailed explanations of how each event listed was caused by the warmer/wetter world is not an acceptable state for science. For instance, the Pakistan flood. It was caused by a blocking pattern. That is the known science that can be determined empirically. Saying "well the earth is warmer and wetter and has more energy so it caused this flood" should not satisfy any scientist. What forces of the warmer/wetter earth made this blocking pattern last longer? Did the warm air push a front into this area that would not have been there had the Earth been 0.8C cooler? Long post but I hope that explains my position on this thread. It is not to deny AGW, if I felt strongly there was not sufficient evidence for this theory I would attempt it on another thread (as has been pointed out to do..keep the focus on topic). Topic here is Global Warming is causing more extreme weather. Only by looking at long term trends in weather and climate patterns will this question be answered to satisfaction. Who knows, maybe I will find enough evidence to see that it is indeed a case. Most valuable to me are the sites that include mechanisms like Rob Painting with his Amazon drought article on this web site. He linked warming North Atlantic waters to droughts in Amazon. A warmer earth would have more chance of doing this over a cooler earth so he is making a link to how a warming world can create a drought condition in a region.

       BBD - there's no silver bullet here. Certainly not nuclear power, or interconnectivity, or storage or gas turbines. It's going to require a combination of all these factors, though I suspect nuclear won't end up playing a very big role due to cost and public opposition. And we're also going to need to increase energy efficiency, and build a smart grid. We also need to keep in mind that weather a few hours ahead of time can be predicted to a high degree of accuracy, so it can be anticipated when windspeed will drop, or the skies become cloudy above a solar plant, for example.

       scaddenp@29: Yes, we heat from Sept to May, and this year most of June as well. I looked at installing a corn burning stove. When corn was less expensive, it was viable. At current prices it is questionable. Your last sentence is the crux tho, and the hardest to address. At some point, elec cars etc will provide more short term transportation alternatives. Even tho I live far from an urban center, I recognize that population density indicates a very good market for such a vehicle. But with that increased load, there will have to be more sources of baseload energy. Long stretches of HVDC lines have a substantial loss so are not feasable. As the price per kwh rises, they become even less feasable. I firmly believe that solar can provide electricity for the sw 1/4 of the US. Hydro should be providing power for the majority of the rest of the country. One of the forcasts of warming, (whether it be AGW or cyclical is not important in this discussion) is more precipitation. Some of these events are suppose to be extreme. There are ample basins to capture the result of this extreme, as it is really only a shift in energy on a pure raw physics sense, and use it for benificial purposes. I am familiar with the topography of the US. I am not sure if this is practical in the rest of the world, but it certainly is in the USA. I look at the bird deaths at the windfarm near me and am troubled by those. They have a great value in the scheme of life. A dam would not be as environmentally degrading and also provide mitigation responses as well as elec generation. A two fold win. If substantial battery storage improvements are not on the horizon, which at this time they aren't, the benifit of hydro/solar is that one can produce hydrogen. From all indications, my source I can't link to, a viable hydrogen fuel cell is not far off the horizon. I am hoping that project is fruitfull. One has seen items close to fruition before only to never quit achieve what had been hoped. These are solutions that can be done, the teck is here for those. By doing so, one could slowly take offline coal powered plants in the USA and have viable baseload energy. These solutions solve mitigation, environmental concerns, and are viable. Any leader worth his/her salt should be able to sell these to the general public. A non political item.....which from what I can see....is a requirement for any advancement on this issue.

       "1/ No matter what happens, sea level will continue to rise. It has been doing that climatically for 100's of years. " 0.3mm/yr over last 2-3 millennia. "The question is, how much additional rise has AGW added to the rate of rise." See the appropriate threads. Evidence says quite a lot. I think a better focus would help. Unless we want to spend all our income on transport fuel, I think the difficulties in maintaining oil production will mean we will be finding alternatives without the need for further carbon pricing. Where you live, it sounds like heating might be a big cost - here it was economic to switch from gas to pellet burners. If it was colder, GSHP might have been better option. Finland and Sweden are into this big time. However, real focus is getting off coal. What does it take to get electricity production from other (clean) sources? Kill the subsidies on for starters.

       Glickstein and WUWT's Confusion about Reasoned Skepticism
       Something else to consider re: the CO2 "lag". Depending on the Earth's orbital eccentricity and the precession angle, there are times when the Earth's NH will receive a good bit more solar energy than the SH, and vice-versa (i.e., if perihelion occurs during the NH summer, then the NH will receive more solar energy than the SH.) But in the past, even during these periods of "asymmetric insolation", the NH and SH have always warmed/cooled together on Milankovitch time-scales. Why is that the case? If the Earth's temperature were driven mostly by changes in solar energy received by the Earth, as some deniers insist, then why haven't the NH and SH been "out of sync" temperaturewise during the times when precession/eccentricity caused the NH and SH to be "out of sync" with respect to solar insolation? Also (straying slightly off-topic a bit here with a "blast from the past"), folks may (or may not, depending on stomach sensitivity) want to look at how some of the WUWT team treated Nick Stokes when he very calmly and politely tried to explain to them the differences between absolute temperatures and temperature anomalies. For folks who understand this basic concept and haven't yet seen Team WUWT in action, the discussion thread over there will be a real eye-opener.

       Tom Curtis Yesterday I asked you to comment on Dr Hansen's cautioning President Obama as follows:

       However, the greatest threat to the planet may be the potential gap between that presumption (100% “soft” energy) and reality, with the gap filled by continued use of coal-fired power. [...] However, it would be exceedingly dangerous to make the presumption today that we will soon have all-renewable electric power. Also it would be inappropriate to impose a similar presumption on China and India.

       I asked you: why do you think Hansen is so concerned about energy policy predicated on the dominance of renewables? You have not responded yet.

       Albatross@6 The reaction to Ferdinand Engelbeen's series explaining how we know the post-industrial rise in CO2 is anthropogenic. It is the one thing in climate change we know 99.9% for sure (barring little green men stealing out atmospheric CO2 for their own nefarious purposes), but there were still members of the WUWT readership who cannot accept that, and think that it is from natural sources. Maybe rather than betting on when the arctic summer will be free of sea ice, we should be betting on when WUWT will have a post arguing that climate sensitivity is about what the IPCC says it is ;o)

       Tom Curtis #87 Apologies - I missed this comment. A few things. First, the numbers are those worked up by Saul Griffith. I merely quote them. I'm sorry you felt that the intent was to distort - as opposed to clarify. You say that the numbers for a switch to renewables as illustrated by Griffith are equivalent to current production commitments based on a no-switch projection. To be blunt, this is implausible and you would need to back it up by breaking down your numbers and contrasting them with Griffith's. Something I note that you have not so far done.

       Camburn said: "1. I do an energy audit on my building and find several areas of leakage. I do a cost/benifit analysis and the payback of insulating, adding new doors etc is 5 years. I do the improvements and have now lowered my costs to less than my compitition and reduced my energy consumption per unit produced." All valid stuff. But there are other issues that affect your income that are not taken into account by the old economics. A very simple example maybe reduced biodiversity. Over say a period of 2 decades, a loss of biodiversity may have an indirect impact on your business. Recently, the environmental costs have been assessed for various types of land and habitat. Although you may consider yourself to be independent of these factors, ultimately the cost is accounted for across the state and nation that you live in. Another example is that green spaces improves health, which in turn reduces health costs. This is now a policy issue in the UK and many local councils are developing policies to cut health bills by encouraging cycling and improving green spaces.

       JMurphy Anyone who says that the anti-nuclear lobby should not be allowed to make comparisons with Chernobyl is absolutely correct. It is a grotesque misrepresentation. There have been no fatalities and none are currently expected. In other words, such contamination as may have occurred is likely to be minor and transient. If you wish to review the facts about Chernobyl (and I suggest that you do), you will find an excellent, unbiased source here.

       A Detailed Look at Renewable Baseload Energy
       JMurphy You and I have a simple choice: back the wrong energy policy and - the lights go out - coal is not displaced from the global energy mix - potentially severe climate change You don't 'like' nuclear, but I don't believe renewables can even come close to the potential for displacing coal. This isn't an argument either of us can 'win'. It's an energy policy debate with a range of downsides. Least-bad outcomes, if you like. You can pose the terrorist scenario; I can counter by asking if you know how hard it would be to cause the release of radioactive material. Recall that modern reactor designs feature containment vessels capable of withstanding the impact of a fully-fuelled large passenger jet. You would need a lot of C4 or whatever to match that. And you would have to get a large volume of explosive past security and up next to the containment vessel. And you still wouldn't break it... You might want to ponder what a widespread and prolonged failure of the European supergrid might look like. How many fatalities would you expect? I had a feeling someone would bring up the news from Japan. Let's remember that Fukushima was a natural disaster that damaged a 40 year old plant which was both poorly designed and appallingly sited. The news about the cesium detected in child urine samples is extremely vague and inconclusive and more accurate information from a large sample is required. It is also essential to understand whether the contamination was from airborne or dietary pathways. It is a matter for serious concern. I don't think we should go any further yet. And I don't like the usual emoting and distorting that is coming from the anti-nuclear lobby either. However, your anti-nuclear sniping requires an answer, and here it is: proper perspective. Nuclear power plants in operation worldwide generate ~375GW of electricity. This is ~14% of the global total. 65 more reactors are under construction, which will add about another 63GW of installed capacity. Since 1951, nuclear has generated 64,600 billion kWh. Most of that came in the last 40 years and most reactors are 20 – 40 years old today. 64,600 billion kWh is a lot of energy. But nuclear has been around for longer than you might think. When the operating histories of all currently grid-connected reactors are summed going back 40 years, they total 11,255 years of nuclear generation. Here's the link. Get a calculator, sit down, and see for yourself. Yet since the vast majority of reactors came on line in the last 40 years, there have been 18 incidents that merited a rating on the International Nuclear Events Scale (INES). It is important to remember that in operational terms, this is 18 incidents in 11,255 years. All bar three were rated as 4 or below on the INES scale (1 = lowest; 7 = highest). An INES rating of 4 is classified as ‘an accident with local consequences’, that is, a minor release of radioactive material unlikely to result in implementation of planned countermeasures other than local food controls. The three rated above INES 4 were: 1979 Three Mile Island (INES rating 5) 1986 Chernobyl (INES rating 7) 2011 Fukushima Daiichi (INES rating 7)

       Camburn: "The economic incentive is then to bring down the cost of renewables so that they can compete." Probably not hugely necessary. Demand for the old fossil fuels is pushing prices up across the board. Including food prices. In the case of some food stuffs organic seems to be comparable to 'conventional' fossil fuel supported food lines. Growth in energy demand and resources in general will make a lot of alternatives economically equitable over the years. Solar energy in particular is due to tumble in cost.

       actuallythoughtful@24: 1. No matter what happens, sea level will continue to rise. It has been doing that climatically for 100's of years. The question is, how much additional rise has AGW added to the rate of rise. A cost of mitigation is going to be dealt with because people are still foolish enough to built houses etc near the ocean when they KNOW that sea level is rising. 2. It takes wealth to embrace new teck. With the current world economics, and the role the US economy plays in this economic situation, the current distress is plainly evident. The level of debt worldwide as a percentage of GDP of the world, is on an unsubstainable trend. 3. We can see that the trend of energy per unit of GDP has taken a turn for the better. Efficiency of production is the leading reason for this. Economics works. 4. Looking at this without predujice, my concern is the economic distress will cause enormous human distress that will result in wars, famine, etc. That is the near term threat of greatest magnitude. Until this is resolved, everything else is on the back burner. Examples of this are Greece, Egypt at present. I would think that people read the news and I don't have to post examples of the unrest. 5. Where there is wealth, that wealth is being used to reduce energy consumption. It is also being used to invest in renewable energy if the economic return is there. 6. From a business standpoint, and one of the reasons you are seeing per unit energy reduction per unit of GDP, is that all information currently available indicates a steady to steep increase in energy costs for the forseable future. Business is reacting to that stimuli, homeowners are reacting to that stimuli and will continue to do so. 7. That reaction will continue as long as there is wealth to do so. Add another tax, that will add another layer of uncertainty to the economy, and reduce the rate of switch as the wealth dries up. In conclusion: The continued rise of energy costs will speed up the transition with the least economic disruption. My lifetime experiences have shown me that government intervention in economic decissions results in poor execution and increased costs. The US medical system is a perfect example when viewed on a long term basis. I think the economic cost per unit of reduction is much better played out without government involvement as the value of dollar spent will be greater, IMHO. Michael: A bit off topic, but yes, black carbon plays a significant roll in Arctic Ice melt.

       2010 - 2011: Earth's most extreme weather since 1816?
       Norman @201, Thanks for the clarification. I have some time here to make a few short posts. Believe it or not your myriad of posts on the extreme threads has given me pause for thought. Not so much on the strength or validity of your arguments, but more so to try and figure out a way of succinctly and clearly explaining the errs of your logic to you. We seem to be talking past each other and my (and other) posts trying to reason with you repeatedly fail. Some poster shave tried analogies. I'll try one more. Let us consider the global SAT record, and let us go back to 2008. Some could argue that 2008 was not consistent with a warming world because it was one of the coolest years on record recently. But that would not be true-- the long term trend is up. Now let us consider 2010, tied with 2005 for the warmest year on record, yet a perusal of the global SAT anomaly map would allow one to identify areas that were below average-- that too could be used to (erroneously) claim that the warming is not significant or unusual. OK, well how about the fact that 1934 in the USA was for all practical purposes as warm at 1998? Surely the timing of those two extremes mean that the planet is not warming or that current temperatures are not unusual? I mean 1934 was a long time ago and anthro GHGs at that time were practically insignificant. But again, one would be wrong to deduce that-- the USA covers<2% of the planet and the planet has warmed quite a bit since 1934. And one and on one can go-- for example, but surely the previous interglacial was warmer than the current one-- indeed it was. Does that mean that the current warming is not unusual? The short answer is no. My point is that one can always seek out locations or times when the data appear to go against the long-term upward trend in temperatures. But to use those data to conclude that the warming is either not happening or not significant is both wrong and misses the point altogether. And seeking out such data is not viewing the body of evidence, but is rather an elaborate form of cherry-picking and argumentum ad absurdum, something that you and both the NIPCC have both identified, perhaps even independently.

       The Planetary Greenhouse Engine Revisited
       Re 54 Michele - you keep coming back to the same basic errors. 1. In your description a few comments back, it seems you rigged the setup to have two levels radiating to space. You then said that the physics may be simpler than we are making it. But I think the underlying physics is simpler than you are making it (what physics could cause two radiating levels independent of composition and at odds with temperature), although the consequences are complex, they are complex in a simple way - I mean, it takes a lot of number crunching to get the results right, but you can understand qualitatively how a lot of it works just by picturing it (think about seeing through a fog. How far can you see. An object fades into the distance. Now consider instead smoke that glows incandescently. Given a particular temperature distribution within the smoke and whatever objects are present, how does the brightness of the radiation vary with location and direction? Sum over direction (properly weighted by geometrical considerations) to find gross and then net fluxes of radiant energy; the divergence is a net radiant cooling rate. Now consider a smoke that is not spectrally grey but rather has absorption and emission lines or bands, of various shapes, etc. You have to use the Planck function now, a more complex relationship than the T^4 proportionality, but nonetheless it always increases with increasing temperature. Absorptivity = emissivity at LTE. If not at LTE, quantitatively things change, but there can still be some qualitatively similar behavior up to a point. In the limit of particles absorbing and then emitting photons of the same energy, this becomes like scattering. You can have a greenhouse effect based on that, too, or also based on scatteriing involving photon energy changes (Raman, Compton, others...)) The cooling effect occurs within the isothermal sinks because the conversion heat->EM radiation, in effect, is a phase transition because the excitation/disexcitation takes place as change of the internal molecular energy which doesn’t affect the translational molecular KE ant thus the temperature. Molecular collisions redistribute the energy among translational, vibrational, rotational, and if hot enough or depending on other things, electronic or chemical forms. The Planck function describes the intensity of radiation that can be emitted given a thermodynamic equilibrium distribution of the energy over these forms (but you can exclude disequilibria that are not 'in play' in the relevant timescale - ie the surplus unoxidized CH4 in the atmosphere doesn't perturb LTE much for the given composition) - and it applies to any volume possessing material of some optical thickness with some temperature, provided the volume is statistically large enough, which is generally not a severe constraint, and also that the volume is isothermal, which is easily approximated by using small volumes. It applies over any time period statistically long enough, also not a severe constraint. Thus a change in temperature over space and/or time only requires using sufficiently small grid resolution to do calculations. Emission of radiation from vibrational/rotational/other de-excitation results in a cooling via providing a sink for translational kinetic energy; likewise absorption results in warming. A layer of given thickness and composition, setting aside line broadenning and line strength variations, will emit more intensely if at higher temperature. The stratopause region doesn't dominate radiation emitted to space at most wavelengths because it is so thin in terms of optical thickness. The mesopause region is much much much thinner. And if, at the same frequency, the tropopause and mesopause can both emit radiation, the would also absorb each other's radiation, to the extent the intervening space is transparent (which it isn't!) and to the extent they can emit (relative to the Planck function). If the mesopause region were sufficiently opaque you couldn't see much radiation from the stratopause or tropopause reaching space. But from the spectra I've see, the upper mesosphere and above is so optically thin you could hardly see any radiation from it reaching space and just about all radiation reaching space is coming from below. At most wavelengths it is coming mainly from below the upper stratosphere - the warmth of the upper stratosphere is responsible for the narrow spike in outgoing LW radiation (OLR) near 15 microns, where CO2 is most opaque; this is within a broader valley of OLR where CO2 is opaque enough for the brightness temperature to approach that of the upper troposphere and lower stratosphere; outside of that CO2 is only opaque enough to block some of the radiation from the lower troposphere and surface. Going outward from 15 microns, the net upward LW flux at the tropopause level increases; adding more CO2 has the effect of broadenning the spectral interval over which a given opacity is exceeded, thus reducing the net upward LW flux at the tropopause (even after stratospheric/upper atmospheric cooling due to the increased net outward LW flux from the stratosphere through both top and bottom) - conservation of energy requires that this results in a build-up of energy below the tropopause. This continues until the resulting temperature changes restore approximate radiative equilibrium at the tropopause. The distribution of the temperature change **below** the tropopause is greatly affected by convection. You can't begin to successfully argue against the assertion that doubling CO2 tends to increase Earth's surface temperature about 3 K, +/- some range (Charney sensitivity - excluding some feedbacks) when you are supporting points that are false or unsupportable while the assertion itself is supported by true facts and supported points.

       Dikran @5, I guess that is the point, from time-to-time a reasoned or scientifically sound post does appear there, but such posts do not go over well at all with the readership. Watts knows that, so he probably has to do so, so as to maintain some credibility, but he also does not wish to divide his readership or educate them with inconvenient truths. Also, posts of the veracity CO2 record are pretty safe territory-- they can still accept that while denying the theory of AGW. I doubt I'll ever see a post at WUWT arguing that climate sensitivity might be close to +3 C for doubling CO2. Or a post stating that the temperature records are robust, the warming is real and mostly caused by anthro GHGs. The most telling and most egregious error made by Watts is that he is reticent to call out and correct the myths, errors and conspiracies that not only appear in the comments but in the feature posts. At the end of the day WUWT is a political site presented under the guise of science, pretty transparent to most people, but sadly enough people have been duped.

       Models are unreliable
       I think, many problems concerning the value of numerical prediction arise from the term "precise". It is widely used here in a binary manner as an all-or-nothing gauge. It would be much better to talk about probabilities and ranges. Concerning the comparison of complex simulation models with polynomials: it is right, that both, because of input data uncertainty ranges, have to be fitted to the past. But in the physical models is so much more information integrated about how the world works, that common sense tells us, that their result is (again probability!) most probably more reliable than a simple polynomial. I am a physicist - I don't pretend to understand every intricacy of climate science though. But that all model output is invalid because of software bugs seems (again!) improbable to me. The models deliver results with a limited precision. But their imprecision is unknown and may lie in either direction. So for me their results represent the center of probability according to the information available. All the more as they are in line with the common sense argument, that if you put in more energy than you let get out, the thing becomes warmer. (- Yes, I know, it's the degree of warming that is disputed. If you want to estimate the degree, you start calculating, and end up at - surprise - numerical models.) And a global AGW conspiracy - seems (again probability!) not very probable to me.

       BBD wrote : "It is impossible to secure a nuclear power station, but it can be made significantly more secure than interconnectors." Perhaps, but which security breach would cause more long-standing problems over a longer period of time, especially if you cannot even get near the problem and have to evacuate a large surrounding area, as would be the case with nuclear ? Which breach would be more quickly alleviated ? (Cesium found in child urine tests) I also agree with what michael sweet wrote : If a HVDC transmission line gets taken out the only problem is lack of electricity at the destination. That can be fixed much more easily that a melt down in a reactor. You also wrote : "JMurphy at 84 asked why the UK government was 'cosying up to nuclear'. It's really very obvious if you know what's actually going on." Indeed. Within two days of the disaster, they really 'knew' what was going on when they stated : "We need to ensure the anti-nuclear chaps and chapesses do not gain ground on this. We need to occupy the territory and hold it. We really need to show the safety of nuclear." And, later : "We need to quash any stories trying to compare this to Chernobyl."

       2010 - 2011: Earth's most extreme weather since 1816?
       DB @ 205 I did visit the D Kelly O'Day site and found his raw data and viewed his various graphs. I will have to do some internet study of statistics to learn the many easy made errors when looking at trends. I am a Chemistry Major with only a surface level of statistics (I have an older brother that is an Accuary who is quite skilled in this math). On Tamino's web site "Open Mind" that Albatross linked to, Tamino did demonstrate how easy it is to manipulate statistical trends to create false and misleading trends. The demonstration he used was Arctic ice and how a short 8 year trend made it look like the arctic ice was recovering. But pulling back and extending the length of time showed that the 8 year increase was only a very small uptick on a much large overall decline. My view is that weather is, at this time, not getting worse and 2010 is not so exceptional. I am not making the claim that continued warming will not lead to an increase in severe weather patterns at some point. I am in strong favor of seeking new energy forms to raise the standard of living for people. As one can see in the IPCC disaster report I linked to earlier, poverty conditions leads to much more death rate when a hazardous weather or geophysical event takes place. Less property damage in a poor country but a much larger loss of life. My favorite choice is the Bussard Fusion reactor which may be able to fuse abundant Boron with a simple proton (hydrogen) without the release of a hot neutron per reaction of deuterium and tritium. This web site is dedicated to science. When I took science courses in College we still performed experiments in lab that have been performed thousands of times if not millions before I did them. I see posts on this page say "Leave it for the experts". That is not the way I was taught science. I was taught never to accept any authority's word on it but to investigate, research and validate the information on my own the best I can. I don't happen to believe weather patterns are shifting to a new extreme and 2010 is the first signs of it. Jeff Masters does think it is a strong possibility. My goal is to either find out if my current view is correct or wrong. I am looking for information that indicates that 2010 is not much different than many years before it (since that is what I believe is correct). As I am looking for information I am reading material from both sides. On the Climate issue I regularly read material from this web site, WUWT, Roy Spencer, Real Climate, Science of Doom and my own searches for various materials after reading a particualar article. I do try and keep an open mind on the issue. I would not be so stupid to stay the course and destroy the planet's ecosystem I live on. I may be a "denier" but I am not a stupid or blind one.
       Response:

       [DB] Again, I applaud the spirit and the effort in wanting to "get it right".  In all walks of life we have the choice to trust the judgement of experts or to learn it from the ground up ourselves.  I do not personally feel the need to recreate the car from first principles in order to drive one. :-)

       But in the selfsame spirit of "getting it right" do not rely on blogs at all (even this one).  Get some textbooks on climate science and statistics.  Read the seminal papers in the field.  Do your own analysis.  In time you will come to discover that those dissembler sites (WUWT, CA, Spencer et al) have "done you wrong".

       And I have never thought you "stupid".

       Glickstein and WUWT's Confusion about Reasoned Skepticism
       Marco, The series by Ferdinand Engelbeen on why the rise in CO2 is anthropogenic was indeed pretty accurate. I tried to support Ferdinand on that one until I started getting a "Forbidden" error when trying to access wordpress sites from the IP address I was using - could be a coincidence I suppse ;o).

       Glickstein and WUWT's Confusion about Reasoned Skepticism
       Actuallythoughtful @1, "Does anyone know of ANY WUWT post that is complete (ie not a cherry pick), scientifically valid and internally consistent?" Now that is an excellent question. Their may be some very isolated examples, but I am not willing to wade though the quagmire of BS to find them. Also, even if a reasoned post does appear there, the comments usually take care of cherry picking, ad homs, distortion, vitriol, conspiracy theories etc., and at that point their host, Anthony Watts, is only too happy to gently encourage them. Remember too, Anthony Watts is close to Monckton and has on several occasions allowed his site to be used from which to launch attacks on scientists. And I'm afraid that BlackBoard and AirVent may be better, but remember that it is all relative to an extremely low standard, if one could even venture to use the word 'standard'.
