dhogaza at 14:07 PM on 3 June 2011Are you a genuine skeptic or a climate denier?
"Yes Nixon did propose, it was the Democrats which refused to sign on." Talk about total simplification of a complex domestic political issue into a partisan "liberal vs. semi-liberal" fight that doesn't recognize the far right that existed in Nixon's party at the time ... Sheesh. Sorry, you flunk the history test. -

Jigoro Kano at 13:34 PM on 3 June, 2011 So your bet would be to increase efficiency of the existing motors and generators by 5~10%. (I have nothing against that, but it's not nearly enough. If you have enough interest in the subject, I suggest further reading to get a grip on the size of the problem. SkS can be a good starting point. Websites of respected research institutions like NOAA are excellent sources if you have some background knowledge.) But still on your idea: how would you achieve that increased efficiency in a way that would not hurt your ideological beliefs? a carbon tax? A directly regulated efficiency standard? Just hope for a cultural change in consumption patterns? -

266, J. Bob, First, as I have repeatedly said, I don't have an opinion, I instead understand the science. If there was some aspect of the science that I felt I did not agree with, then that would be an opinion (because I'm clearly not as strong at the science as a working climate scientist), but the only times that has happened in recent memory have been with Lindzen, Spencer and other "denial" science findings. Even then, I usually withhold my own judgment until rebuttals from professionals hit the streets and confirm my own insights (or not, if my own criticisms were mistaken). With that said, as far as anything like graphs showing a strong correlation of temperature... the issue is far, far more complex than one set of graphs could ever represent, and as I've said, my body of knowledge is that of science. I don't have my own personal approach to how or why climate is doing what it's doing, and I'd look pretty far askance at anyone else that claimed as much... and there are a few characters like that on the Internet (co2isnotevil being one big one). [I'd also point out that just the way that you phrased your question... a graph showing a strong correlation of temperature & CO2... rings all sorts of "this is a game" bells in my head. You'll never get that, because the system is too chaotic, there are too many conflicting factors and there's too much noise. That doesn't mean one can't understand what's happening, it just means one can't water it all down to a simple, obvious, indisputable correlation on a single graph of just two variables. So if that's what you need to be convinced, then your entire approach is too simple, and there's no point to continuing. It would be like trying to convince a small child that there are no actual miniature people inside the television. It doesn't work that way, but a child doesn't have the background knowledge to understand radio waves and image encoding and photon emissions, so the conversation there has to end with "trust me, there are no little people in the TV."] If you are saying that you honestly, really, are open minded, and want to learn more about the science (rather than to somehow convince me that you understand things better than all climate scientists), then you are welcome to join apiratelooksat50 with me (assuming he accepts my offer) on some other thread, to look at some focused segment of the science and to be sure that it is understood thoroughly and completely, so that it can become one set, indisputable piece of the puzzle. Then, progressing from there, when one has enough pieces, one can say that they understand. But if what you want to do is to engage in a mindless back and forth of tit for tat arguments, each of which is merely a microcosm of the big picture, and every time one side "scores a point" the other side just changes the subject and diverges into a different line of argument... well, that's a complete waste of time. -
scaddenp at 14:03 PM on 3 June 2011Are you a genuine skeptic or a climate denier?
J Bob - the correlation you are looking for is with total forcings - no one claims climate is single factor. And the paper you looking for (apart from figs in AR4 showing match of models to recent climate) is Benestad and Schmidt. For a simple correlation of CO2 and Temperature see here but this ignores the other factors. -
Jigoro Kano at 14:02 PM on 3 June 2011Are you a genuine skeptic or a climate denier?
dhogaza @ 258 You said "As an example of how far right the republican party has moved since the Nixon administration, Nixon gave serious thought to a negative income tax such as proposed by jigoro above as a replacement for welfare payments. As opposed to, oh, you know, just letting them starve. " This system of taxation was a construct of Milton Friedman. Yes Nixon did propose, it was the Democrats which refused to sign on. Letting go of that voting block would be to costly. What was passed, the Earned Income Tax Credit, giving the benefit so long as the recipients remained under the D's thumb. ie. straight up redistribution. If proposed now dhogaza, the only nays would be the donkeys and Obama. -
Ari Jokimäki at 13:42 PM on 3 June 2011Database of peer-reviewed papers: classification problematics
One thing to note here is that apparently the argument of the classification seems to have changed. At least I understood from Eric the Red's original question setting that the argument would be something like "CO2 effect is weak" or perhaps even "it's the sun", but now you seem to be arguing about the argument "climate sensitivity is low". For that argument Eric the Red's original setting didn't give enough information so for that argument the hypothetical paper should be in "neutral" bin. Information missing from the setting are at least the effect of aerosols and the amount of warming that goes to warm the ocean and doesn't show in the surface temperature record. These both are effects that can mask lot of CO2 caused warming. You need to have total sum of forcings before you can determine how strongly feedbacks are acting. -

Camburn, You wrote "GISSTEMP says that where I live, the temp has risen 1.4C in the past 120 years. Yet, when looking at the past 20 years, using state climatological numbers, the trend is down by over .3F per degade." So with the GISSTEMP statement, are you comparing the annual anomaly for a grid cell covering North Dakota or part thereof in 2010 versus 1890 or fitting a linear trend to all the annual anomalies from 1890 through 2010 for a grid cell or looking at only the station nearest you used in their analysis or doing something else? Also, where are you looking up state data for the past 20 years? I'm not immediately seeing, when I search, that that's available from any state agency in tabular or graphical form. I'm interested in checking out the accuracy of your statements, if only because recent cooling at the rate you claim in an area where you also claim GISS says the warming over the past 120 years is quite a bit higher than the world average is somewhat surprising but I find it hard to believe it will produce anything other than a demonstration that there can be considerable regional variation about the global trend, partly because even the people here - http://www.mitosyfraudes.org/Calen4/Ghostbusting.html - who refer to the "IPCC. and its cohort of alarmists" appear to have concluded in 2004, using USHCN data, that temperatures had gone up by just over 1C in ND since 1900. That seems to be based on taking a simple average of all the available temperature stations in the state so the method is less sophisticated than the GISTEMP analysis. In any case, if even dedicated skeptics of global warming agree with GISTEMP that the temperature has gone up in ND by more than 1C since 1890-1900, then I can't see why I should believe that the GISTEMP numbers are somehow called into question even if you're correct about the trend over the past two decades. Or were you driving at some point other than to suggest that the GISTEMP results are untrustworthy? All of which leaves aside the fact that North Dakota is quite a small part of the globe.Response:[DB] I have looked at Camburn's claims in his comment and have found them...lacking in accuracy.

J. Bob at 13:34 PM on 3 June 2011Are you a genuine skeptic or a climate denier?
dhogaza @ 254 I was carrying scaddenp @ 246 view to it’s logical conclusion. You might want to check that post. Sphaerica @ 246& 232, I simply asked if you posted some of your personal analysis to back up the opinion you present, like I did a J. Bob @ 52. I take it your position is that man (via CO2) is the primary cause of the global temperature increase, in recent, say 50 years or what ever. So I’m simply asking if you personally can produce some analysis ( like a graph(s)) showing a strong correlation of temperature (i.e. accelerating global temperature increase) & CO2, using the longest (150+ year ) reputable temperature records. That would help to bring me out of the skeptic camp. -
Jigoro Kano at 13:34 PM on 3 June 2011Are you a genuine skeptic or a climate denier?
Alexandre @ 262 My apologies, do to the redistributive context of my post, I thought you were speaking of indigent mitigation. First off, I do not view anthropogenic CO2 as a problem. So imposing legislation to fix an non-problem, seems a bit ridiculous. More importantly, cap and tax will only enrich the politicians and well connected. If the goal is to reduce CO2, the answer can only come from fossil fuels and oil in particular. No other fuel source has nearly the power density, save nuclear. So although a internal combustion engine is only ~20% efficient, it can produce several hundred time the volume/work as a battery. Increase that efficiency by five or even ten percent, US CO2 emission will plummet. It is this goal which enviromentalist should pursue. -

scaddenp at 13:25 PM on 3 June 2011Are you a genuine skeptic or a climate denier?
Eric, have you read Von Schuckmann and La Traon? I dont buy the "unknown" bit at all. The 3.7 W/m2 is corroborated by glacial/interglacial and volcanic data but is actually a model output. It also tracks pretty well with temperature data to date. If you think it "unknown", then I assume you are also considering that it could be 4-5? To be honest, it looks to me more like your objections are based on hope and distaste for political solutions than on examination of data which surprises me. And the question I ask in hope of every liberatian - if you did become convinced that it would be more cost effective to limit emissions now rather than pay the cost of adaption in the future, what measures would you support for that limitation? Its a hypothetical question - if you became convinced... -
Tom Curtis at 13:21 PM on 3 June 2011CO2 limits will harm the economy
jigoro kano @31, thoroughly of topic, but property can only exist because of "redistributive taxation". In the absence of assigned property rights, any person can make use of any space or resource as they feel fit. In declaring that some piece of land is the property of a particular person, the government (as agent of society) takes away the rights all other people had with regard to that piece of land, and assigns those rights exclusively to the new land holder. That is a redistribution. So, if there is a blanket ban on redistribution, the government cannot sell land to any person, nor can it defend the "rights" of any person to any particular property they may claim. Further, when assigning rights to land, the government (as agent of society) retains certain rights over the land and requires compliance with certain conditions for the land holder to retain the land. Those conditions include the paying of taxes. The obligation of the landholder includes paying the taxes but that obligation does not carry with it any right to restrain the governments use of the taxes. Suggesting that it does is as absurd as suggesting that because you bought something of me, that gives you the right to limit who I can give my money to. (As a side note, taxes are a condition of certain services provided for us by society, primarily through its agent, the government. Any person should be entitled to refuse to pay those taxes, but only on condition that they no longer accept the services. Those services include citizenship and residence rights. So while it is probably wrong to jail anybody for tax evasion, it is doubtful anyone would prefer the truly just punishment for tax evasion of being stripped of their citizenship, and exiled.) Finally, I have yet to meet a person consistent enough to argue both against redistributive taxes and against other legislative methods of redistributing wealth, in particular, the existence of corporations, the existence of limited liability, and the existence of a constant slightly inflationary economy. Can you be the exception? Can there really be just one person on Earth for whom right wing economic theory is a principled position rather than just another self serving ideology? I doubt it. -

jigoro kano @29, public transport is inefficient where it is inefficient, only because of a lack of passengers relative to the service. If there is an over investment in private transport, the consequence will be apparently inefficient public transport because potential passengers will be drawn away by the hidden subsidy. -

The L&P effect seems very effective in this cycle, and there have been so many false alarms as to start up that it is hard to have much confidence in any prediction. And as far as GDP and energy useage, yes, that should be the metric, not per capita as per capita is more a metric of production than useage as an individual.Response:[DB] "I wouldn't put too much credence in solar cycle 24 ramping up anytime soon."

"the real metric to look at is energy use per unit of GDP." No it isn't. That's a lame rationalization suggesting the climate allows for GDP. The only things that matter are total global pollution levels and the rate of additional pollution. Quoting GDP intensity levels is the first hint of pro-pollutionist word-spin. Cadbury's reference to the Lindt word-jumble is refuted here: http://tinyurl.com/3wqrl5s It's basically trying to make the worst-case the mid-line (pin the tail on the alarmist), while it glorifies the supply side. Voice of Reason's argument is just demanding that the warming obey 0-delay commands. It doesn't. Set your stove to 400dF and count to 10, if the oven isn't 400dF ... there's something wrong with the theory of ovens. What really happens is what is really observed and recorded. The science lays out the mid-line. The thing that's affected recent trends is a series of La Nina's, a long solar minimum, and some exceptional global wetting (which is the perfect transport of heat into the ocean). The 'slowdown' has also recorded the record-setting temperature levels and extreme events that walks and quacks like an AGW. There hasn't been any cooling trend for over half a century. The article illustrates that the public and private sectors worldwide are on a fossil-fuel expansion binge. The next 'boom' is going to knock the levels and rates off the charts. The world walked away from common sense when it trashed Kyoto. It destroyed Copenhagen with a B&E. Add to that the next El Nino or two; and the ramp-up of Solar Cycle 24:Now synthesize a forecast onto the graphs:
(currently a record low)

257, apiratelooksat50, If you have serious questions, I'll try to help. If you have leading questions, trying to make a subtle point -- and I'm not saying you will or do, I'm saying it happens a lot -- when it does happen I get fed up and argumentative. If you want to learn, don't label yourself a skeptic. If you're learning, and trying to decide what to think, then you don't need a label, and the deniers have tainted the skeptic label with a new connotation (i.e. someone who thinks they already have all the answers, and don't want to learn). So if you're honestly extending an olive branch -- and I do think that it's very important that you understand all of the science, because you are teaching it to our youth -- then by all means, please accept my apologies, and I will be as patient and straightforward as I possibly can, and I will accept all of your questions at face value, as serious questions looking for answers (rather than as sparring, probing jabs, looking for weaknesses that you can exploit when trying to score points in a game). As far as numbers vs. naturalist. I'm not sure what you mean by a naturalist. I am a systems person, and numbers are one type of system, but for me, in my mind, everything fits together, in systems and subsystems. When I understand all of the subsystems (or branches, if you will) using whatever language is appropriate (numbers being one of them), and I understand how they all fit together, then I understand the whole. So please pick a topic that concerns you, find the appropriate thread, point me in that direction and ask a question there, and we can try to find and fill the gaps. -

apirate @260 "You and I agree at least on one thing: the ability to learn and understand is what makes humans human." No. As has been shown by anthropologists what makes humans human is the ability to socially groom each other by speech, which allows interaction and cooperation in large (>50) groups, an ability lacking in all other anthropoids. As a result, cultural advancement in most hominid species was glacial, with only a few cultural changes (with accompanying improvement in stone implements) in two million years. The laughingly inaccurately but self named Homo sapiens sapiens advances at a lightning fast rate by comparison, but still took 190 thousand years to go from hunter gatherer to agriculturalist, and that in only a few places in the world. Since then advances have been faster but only because extensive trade networks and high populations have allowed the innovations of the very few to propagate faster. Despite those advantages for cultural spread, advance from agriculture to industrialisation took over ten thousand years. This painfully slow progress was not because the ancients where unintelligent compared to the moderns. In fact their mental capacity was on a par. Rather it is because while human cognitive capacity is well beyond that of any other species, we are not very good mathematical, logical, or technical thinkers for the most part. For most of us, our social intelligence is massive - of the scale compared to other species - but our scientific intelligence is rudimentary. There is a reason why soap operas are overwhelmingly more popular than documentaries, and why nature documentaries focus on the social interactions of animals rather than on ecological relationships. There is also a reason why even the brightest of humans will sometimes have massive blind spots in which they are apparently incapable of rational thought. (Alfred Russel Wallace comes to mind.) Given this situation, in which true rational thought comes hard, and hard earned to most people, "educating" them by trailing examples of superficially attractive but shoddy reasoning across their trail is doing them a massive disservice. It is inviting them to be caught up in a self reinforcing rationalism. To be in denialism in fact, whether denialism of human evolution, of moon landings, or of global warming. It is a massive indictment of western education that so many of the population are, not unintelligent, for they are very intelligent, but uncritical reasoners. This includes the majority of university graduates, who are intent on learning a body of knowledge rather than a suite of skills. To examples from contemporary Australia illustrate this massive cognitive dysfunction. The first is the most common meme on climate change in Australia at the moment. It states that a carbon tax in which consumers are paid compensation equivalent to the average impact of the carbon tax, but independent of their actual effective emissions cannot reduce carbon emissions. This is seriously asserted by people who in other areas are fierce champions of market mechanisms. Apparently the "invisible hand" considers anything to do with carbon reductions untouchable. The other example is the claim that recent floods in Australia disprove global warming because AGW educators have repeatedly asserted that increased frequency and intensity of droughts is an expected consequence of global warming (in some areas of Australia). This claim is easily checked by referring to the actual reports. I have read around 10 such reports dated from 1990 to 2010, some explicitly dealing with flooded areas (the Brisbane River) and every on of them has asserted that increased intensity of rainfall in peak rainfall events is an expected consequence of global warming. Apparently the minimum level of critical thinking called checking sources is to much for many Australians. So, what makes us human is not our massive cognitive intelligence, but our massive social intelligence. That is why denialism prospers. -
adelady at 11:56 AM on 3 June 2011Are you a genuine skeptic or a climate denier?
Most of all it isn't the AGW we are currently enjoying and adapting to, ...we will somehow lose our ability to adapt. For example polar bears could thrive in northern areas where they currently only have a short active season ... But somehow that's just not possible?? Whaaa??!! Polar bears are specialists. They are ambush hunters which rely on sea ice, not land ice, to get among the seals. Their "short active season" is a simple seasonal matter. Abundant calorie rich food during the hunting season. Minimal calorie expenditure during hibernation. 'Adaptation' is not a matter of a few decades. It takes dozens, if not thousands, of generations for a large, long-lived animal to change firstly its behaviour in response to change, then its genetics to entrench those changes. If we want to see polar bears survive long enough to thrive in a hugely changed environment, we'll have to slow down the loss of sea ice. -

Sphaerica @ 206 other tread You are completely and utterly wrong about SS. It was never intended to be a retirement program. It was intended to be a insurance program for those living in excess of life expectancy. SS is constructed as a ponzi scheme, current retires are dependent on the still working. The "Lock Box" Gore talked about is filled with IOUs. With true unemployment approaching 20% there will soon not be enough coming in to secure the increasing elderly population. So to the contrary, SS and all entitlements will be this countries undoing. BTW, I agree defense needs to be drastically cut but consider two things. National defense is a Constitutional mandate, though wars must be declared by congress, not presidential decree. Entitlement account for the largest portion of the national budget. -

dana1981: The USA will not do cap and trade anytime soon. And it isn't because of Republican nor Democrat. We are a sckeptical bunch, we always have been. And we recognize the benifits of energy. People talk about energy useage per person, but the real metric to look at is energy use per unit of GDP. The USA is reeling right now because of the non funding of 2, and now it seems 3 wars/police actions. The price of fuels, diesel and gas, has risen over 25% in the past year. This has been a shock to the economy that may turn the mini recovery into another full blown recession. No matter how you cut it, if you derail the worlds largest economy, people throughout the world will suffer. Until we get government spending brought under control, no carbon bill will pass. And I do believe that during the next 2 budget cycles, the EPA will be stripped of money to enforce what they think they have reasonable grounds to enforce....co2. Most of my friends hold some type of college degree. They look at figures like accelerated sea level rise and say.....what percentage rise is this verses the previous trend. Then they look at it as nothing important. GISSTEMP says that where I live, the temp has risen 1.4C in the past 120 years. Yet, when looking at the past 20 years, using state climatological numbers, the trend is down by over .3F per degade. Our Januarys in the 2000 decade have been cooling at a rate of 6.7F per decade. We also have some long term climate cycles as verified by cores of earth and tree rings. By long term I mean approx 160 years. It comes back to the sensativity and what each person percieves it is. Also it comes back to being educated and understanding that when a model can't do a very important part of climate, the hydro cycle and clouds, that the hole is too large to give the model much credibility. I, personally, know that research is being done to try and close that gap, but as yet, it isn't even close to being closed. Just some reasons that the USA will not go along with government carbon taxes or government mandates. The economic reasons are already there, and people take them seriously. Insullation is being installed in older homes, new windows, smaller structures being built etc. A lot being done on an individual bases that does not get reported. Fossil fuels will be a minor source of energy in 30 years, and the reason is that someone will come up with a way to provide energy at less cost than fossil fuels.Response:[DB] "GISSTEMP says that where I live, the temp has risen 1.4C in the past 120 years.

Sphaerica,Tom Curtis @ 25 26 27 other thread 212 Public transportation is inefficient regardless of the subsidy. The US light rail inefficiency arise from the constant power consumption. Whether it running full speed, half speed, idling or breaking, nearly the same power is consumed. The large cages, usually atop a the trains, contain a huge resistor grids. The grids act a giant rheostat to offset actual use to mitigate dynamic loading of catenary and/or third rail. Worse yet, being a government entity they operate on the 'use it or loose it" budgeting criteria. Budgeted money not spent is retracted and counts negatively (less funds) the following cycle...thus system manager leave surplus trains idling to burn electricity. Why you ask, well being a wholesale consumer of electricity, overages in negotiated electrical rates cost little, and show a need for bigger budget (tax money), and if overages are substantial enough a better negotiated rate. Under use will do just the opposite. Whats' the result, the CO2 ton/rider ratio is abysmal, while the cost/rider is exorbitant. As I said inefficient. Inefficiency to a level unheard of within the private sector. If I had my druthers all roads would fall to big oil for construction and maintenance. Who has more interest keeping the roads operating at top performance. Maybe OT but private schools out preform public. Private schools out preform at a lower cost/pupil. You need only look at the charter schools in the major cities as evidence. Yes this is a hybrid, public money private schools. However, these school cost less and perform better and highly sought by those trapped in fail, expensive public schools. -

scaddenp (245), thanks, and I'll read between the lines that I can do better here away from threads like this one. Honestly, I read the entire CATO monthly editorial clippings. I happen to agree 100% with the set of non-CC opinions (currently on the CATO home page). When it comes to CC, it is one more topic I read with some interest but they often reveal little I don't already know. I rarely look at or listen to any multimedia, but I just listened to Michaels daily podcast. He points out that luke warmers anger "both poles of the debate". He says they (luke warmers) believe CC is "real", "modest" and "below the statistical rates predicted by climate models". "and there's not very much you can do about it". #1, 2, and 4 are fine by me, #3 is debatable and probably irrelevant. Then he mentions that Greenland was warmer for a few millennia and "there absolutely no evidence" that it lost its ice and sea levels went up 25m. True literally, but http://www.sciencedirect.com/science/article/pii/092181819090010A states there is some evidence "suggesting significant middle Holocene retreat of this portion of the GIS" Then he suggests that all papers should put every manuscript online along with their editorial decision and all reviews because that would mitigate what he sees as extremes. Well, that's nice, but he didn't read the paper I linked (extreme or not). Two things come to mind: he's lazy and it's an opinion piece. I suggest the policy studies in the top right on this page http://www.cato.org/global-warming Those go straight to the policy and can be considered somewhat independently of one's views on CC. I agree with their policy conclusions. For defining CAGW, it's everything that AGW isn't. It isn't 0.85 W/sq meter of accumulation, it is an almost completely unknown (ocean turnover etc) future accumulation. It isn't 3.7 W/sq meter for doubling of CO2, it is a an unknown feedback which can't simply be extrapolated from glacial to interglacial feedback (they are completely different weather and other dynamics). Most of all it isn't the AGW we are currently enjoying and adapting to, but something new and shocking and we will somehow lose our ability to adapt. For example polar bears could thrive in northern areas where they currently only have a short active season (unlike the south where they may disappear with the ice). But somehow that's just not possible??Response:[DB] "there absolutely no evidence"
Michaels is absolutely not looking then. To piggyback on the paper you reference, Weidick et al 1990 (which stated that Jakobshavn Isbrae had retreated inland by 15 km inland from its mid-1980's extent), evidence from Briner et al 2010 shows that the recent recessions of Jakobshavn Isbrae have brought it further inland than at any point in the HCO:
The ice front from Weidick 1990 is represented by the 1985 line. By 2008, the calving line had retreated more than 15 km inland from that point. Subsequently, Jakobshavn Isbrae has retreated inland even further than that.
And that's just one paper. Many more exist.

As an example of how far right the republican party has moved since the Nixon administration, Nixon gave serious thought to a negative income tax such as proposed by jigoro above as a replacement for welfare payments. As opposed to, oh, you know, just letting them starve. -

Sphaerica @ 226 You and I agree at least on one thing: the ability to learn and understand is what makes humans human. I'm intelligent and educated. I'm open minded. I certainly have not sold out to make money. As a matter of fact, I took a 50% paycut so I could teach public high school. I could not do that until my environmental engineering consulting company had enough business to allow me to support my family on a teacher's salary. I'm not telling you this to earn any sort of praise - it's just the truth. I've tried to establish an open line of dialogue with you, but wound up getting lumped in with one type of zeaolots. You are more of a numbers person and I am more of a naturalist. You base your decisions (I think) on the numbers, while I base mine on what my knowledge of the natural world is. Bottom line: if you want to teach - then teach. I'm open. I've stated my position. If you want to call me a denier - then do so. But, that is a disservice to your goals. You can create a vocal and educated and influential adversary, or try to bridge the gap. I extended the olive branch - I was hoping you would grasp it. -

Alexandre @ 205 you asked: What's your suggestion for a mitigation policy? (forgive me if I missed it in some previous post of yours. I did not follow your whole conversation.) Not at all discussed, not sure if it's germane to the thread. Ideally a fair tax (consumption). But ours is a nation dependent on handouts, so weening off lethargy will take some time. To get there we should first eliminate current individual and corporate tax, all welfare and food assistance, all corporate welfare. Replace with a flat negative income tax for individuals and a flat 10% corporate tax. All individuals treated equally all corporations treated equally. Flat negative income guarantees a minimum income (rebate) to all adult individuals, while imposing a flat income tax. Example, $10k rebate per adult 20% rate on all income above $10k. Choose to not work, live off your $10k. Earn $20k pay $4000 in tax live off your $26k. Make a cool million pay $200k in tax live off your $810k. This system would allow the indigent to earn without loosing their assistance while providing a safety net, not a hammock. All would have skin in the tax game. -

Agnostic - Australia seems to be trying to do something about the issue, which is a good start. The USA is the big problem, and Republicans are of course the obstacle behind US action, and behind Republicans is the fossil fuel denialist industry. As an American, I don't know what we can do about it, other than try to get global warming denying Republicans out of government. Unfortunately a large segment of the US population either also denies the global warming problem, or doesn't consider it a priority. So we have to convince them otherwise. Until the US takes serious action, we can't expect China or India to do anything either. Nor will Canada, and so far Australia has waited for us too. -

voice of reason - you're not making any sense. You can't just pretend that the unrealized warming won't be realized because it hasn't been realized yet. There's a global energy imbalance, and until the climate reaches equilibrium, the surface will continue to warm. That's not a controversial concept. Denying physical reality will do us no good. -

Tom Curtis at 10:20 AM on 3 June 2011CO2 limits will harm the economy
Sphaerica @27, a case can certainly be made that the rich benefit more in absolute monetary terms. I, however, would argue that the correct terms of analysis are in terms of utility gains (where "utility" is the technical term used in economics and ethical theory). As absolute income increases, utility gain per dollar increase in income declines, and quite sharply above a certain point. Just one example, in 2000 dollar terms, the difference between an annual income of $5000 and $10000 is the difference between a life expectancy of about 50 and about 75 (from memory). The difference between an annual income of $10000 and $50000 in contrast is only a difference of a life expectancy of around 75 to less than 85. So, in utility terms the gains of the poorer members of society from the transport system are massive. So also are those of the wealthier members of society. But it would take very careful analysis to decide who gained most in relative utility terms. -

If you think there is a problem you will naturally want to do something about it. Meanwhile we're half way along the IPCC path already, we have almost half the doubling of 260ppm and as a result agreed increase in average temperature is 0.8C. That is the actuality, no future projections or complications. Take that as our known (as opposed to futurism). The 1C rise with no feedback is something which to my knowledge never expected the feedback to be delayed. In fact if this had been the case it would have made the prediction almost impossible as they were looking for a previously unseen and as a result unknown phenomenon. But as the expectation was a possible 2-400% increase over base level then as we now have an actual extrapolation heading way under the 2C rise for 2100 (I'm not sure why you use this point as we won't be here to know and as such is untestable and therefore unscientific). Therefore you are imagining an as yet absent positive feedback. Unless you can demonstrate beyond reasonable doubt that this feedback may be delayed then you are not describing reality with the above mental exercises. -
Tom Curtis at 10:08 AM on 3 June 2011The Critical Decade - Part 2: Climate Risks
Ken Lambert @24, Hansen looks at the best 6 years of data we have to draw a conclusion, but considers the remaining data to be a reasonably accurate indication of what happened in those years. He also looks at the six year data for from 0-2000 meters plus other data for deeper than that. (-snipped-] on this site have tended to look at only the 0-700 meter data, and to argue that pre-2003 data should be totally ignored. The difference is that between a comprehensive analysis and cherry picking. -

Dr Jay displays such lack of information about clean energy that it is difficult to believe that he is either a “Dr” or a “PhD”. How about a bit of biography “Doctor” or is it all pretention? Anyone with the slightest knowledge of the consequences of a 3°-4°C rise in global temperature by 2100 will realize just how bad the bad news conveyed in this article is. It comes as no surprise that rather than reduce emissions with a view to achieving a tolerable CO2 concentration of 350ppm by 2100, we face the dual prospects of 800ppm and a climate so dangerous that it seriously damages human habitat. If we do not reduce our emissions significantly starting now “nature” will take care of the pollution problem by eliminating those responsible for it – which is almost all of us. Little wonder that the German Chancellor has decided to adopt a renewable energy future and that the UK had set an even higher emissions reduction target – 50% by 2027. However, unless all countries do likewise, forget a habitable planet. The message is clear, so is the course of action which can be taken to avert a bleak and short future. The only problem is that most governments are not prepared to heed the message or take timely action. Any suggestions on action needed and how to persuade governments to take it? -

Looks like an excellent report. My only gripe so far is that they didn't address the likely/possible effects on Australian agricultural production, though I understand such things are very difficult. Still, some mention of likely declines in crop yields at various temperature rises would be relevant to one of the major breadbaskets of the world. -

We have known we can harness the power of the sun for a very long time. Same with lightning. I have to add that it's ridiculous to conflate solar power and harnessing lightning. They present totally different engineering challenges, and we certainly have not "known for a very long time" that we can use lightning in place of fossil fuel energy. I'd hope that even the worst pro-FF zealot would be willing to concede that the problems with solar power are a lot more tractable. But if not, here's a hint: people are actually running their homes and businesses on solar power. Lightning, not so much. -

michael sweet #22 "Jim Hansen draws a conclusion from 6 years of Argo dat abecasue that is all the data that is available." Quite right Michael. Jim Hansen seems to think it is legitimate to study and quote the Argo record by itself. Which I agree with because of its vast improvement in spatial coverage over prior methods. I would point out though, that if I do the same thing - Moderators and others on this site label me a 'cherry picker'. -

When I see comments like #4, it is frustrating. Scotland's going for 100% renewable by 2020, and the UK government has made commitements for beyond 2020. I'm not saying it'll happen (politicians involved), but there is a big push in the renewables industry, including wind, wave and tidal installations aiming to provide 1GW of Scotland's target from northern Scotland. Regardless of the politics, the long-term aim is positive and reasonably achievable. With the technology rapidly being proven and deployed in places like Orkney and Islay, and the cost per watt dropping steadily, it's something to be optimistic about, despite the bad news on CO2 emissions. There is certainly everything to gain by being positive about the possibility of providing for our energy needs in a carbon-free way that does not require a constant supply of fuel from politically unstable countries. Prices are dropping, and are rapidly becoming competitive, and dana's car analogy is an excellent one here. Clearly the concern is the increase in CO2 emissions from India / China, and the lack of action in America, but we can only hope that as dirty fuel prices rise rapidly and renewables prices drop, the economics will make the transition to renewable energy as obvious a choise as the transition from horse to car... -

253, adelady, Absolutely, yes, and a very important distinction. "Skeptic" does not mean crotchety old man who won't believe anything unless he see it with his own two dang eyes. It means someone who is not instantly suckered in by the "obvious" statement (i.e. is not gullible), and instead waits to get more information, weigh the facts, and comes to his own, reasoned conclusion (or follows and accepts the reasoned conclusions of others).
