Tom Curtis at 19:10 PM on 4 June 2011CO2 limits will harm the economy
Jigoro Kano @43, the fares for the New York Subway are actually 2.25 per trip or 2.50 if you buy a traditional ticket. Further, children accompanying an adult ride free, and the elderly and disabled can ride for $1.10 per trip. I do not have the information to turn that into an overall revenue for the Subway. I do know the MTA has an estimated fair revenue across all services of 4.5 billion dollars for 2010. That indicates that free and discount trips (possibly along with fare evasion) eats substantially into their revenue. I will say that NY public transport fees are absurdly cheap when compared to those of, for example, Brisbane. As to the direct issue of public or private ownership, it makes no difference to the train driver of conductor whether their salary comes from a corporation of a government. Therefore it is not the case that public enterprises are inefficient, while private ones are efficient. In fact, having worked for large public and private enterprises, the most inefficient, bureaucratic and corrupt enterprise was the private corporation. What is very important is the system of management, and public enterprises often fall into bad systems of management. That is not an argument against public enterprise, but for efficiency driven, accountable management in public enterprises. -
Glenn Tamblyn at 19:06 PM on 4 June 2011Of Averages & Anomalies - Part 2A. Why Surface Temperature records are more robust than we think
Thanks for the typo fixes one and all. Warm, ETR Interesting paper by Rigor et al. When you think about the result, it makes some sense. In winter up there everything is Ice & Snow. In one sense it is ALL 'land'. So you are far more likely to correlation between 'land' and 'sea', particularly when you factor in the known phenomenon that air temps immediately above Snow/Ice are largely set by the snow and ice. In summer when the land is dark and ice free, and at least some of the sea is open water, the more usual ralationships between land and sea reestablish themselves. Skywatcher. To my knowledge, based on the data that GISTEMP put up, they rely on the available SST data for oceans and this doesn't cover the Arctic ocean since it isn't available where there is ice cover. And using data for only part of the year would a big No No. The phenomenon you describe is real and has an impact although there will be a limit to how high above the ice this extends. Conversely, this will not have the same effect in winter. Arctic warming can quite easily be extreme if winter temps moderate significantly even if summer ones don't. Less cold in winter impacts on sea ice thickness, snow cover thickness etc which then shows its results in the melt season even if the summer temps haven't changed as much. Climatewatcher. Yep, most of the metrics for temp change are pretty much in sync. You might be interested in this earlier post I did some time ago on satellite temperature products My take home from putting all this together is this. The method used by HADCruT (and NCDC, JMA) will underestimate global temp changes in a world where the arctic is warming more than the average. GISS will be closer to the reality although whether they over or under estimate is hared to say. WRT to the RSS & UAH Lower Troposphere satellite temps (LT), they are convegring as processing errors are resolved. Also there is a residual impact from the effect of a short overlap time between the NOAA 9 & NOAA 10 satellites that is playing through their differeing analysis methods. As I discuss in the earlier post, there is reason to think, from other analyses, that RSS & UAH may be underestimating the trend somewhat. Your graph also includes MT series from UAH & RSS. As I discuss in the earlier post, these trends are unphysical, being influenced by an impact from stratospheric cooling on the results. The only satellite temp' products that are close to being useful as presented are the LT series and the LS (Lower Stratosphere) series. So my take home from the take home. The temp records show quitre amazing agreement given the compexities of generating them. Kevin C You have to LOVE those names.

I just want to underscore the raw power in reclaiming your own personal energy independence. When you can heat your home, power your devices, and travel without relying on a monopoly provider - life is definitely better. This is the end result of NOT being a skeptic/denier. Anyone who understand the science is (morally/ethically/financially/practically) compelled to take action. The most logical action is to harness the power of the sun directly on your own property (assuming you own property). There will eventually be issues with relying on the grid (yes, that evil monopoly I just mentioned can be perverted for good) - but we are far from that issue, and early adopters (sigh - still early adopters in 2011...) can benefit from their (relatively) quick action. And controlling your own heating/cooling doesn't require any grid at all - just the willingness to invest in your financial well-being, and the future of happy humans on earth. -

Jigoro Kano at 16:40 PM on 4 June 2011CO2 limits will harm the economy
Tom Curtis @ 42 Nice work finding this gem. After reading it, I need to make a non-pertinent correction to my 29. The NYC subway and others listed within CBC are considered Heavy Rail not Light Rail as I posted. I should say it makes a small difference when readings e @ 40 post. If not publicly owned, not publicly subsidized the NYC system would be much more efficient and profitable. Being public makes it's a bastion of corruption, but that story is more OT then we are now. I do not object to mass transit, I do object being forced to pay for it. Taken at face value, you'll notice NYC has more riders then all other municipalities combined. With the highest US population density, obviously the best suited for a mass transit system. The calculation as listed CBC-NYC however, are a bit curious. 1)For example, look at the Daily Passenger Trips: 6,461,133. For a population of 8.3 million the ridership seems a bit unrealistic. Assuming this count includes a rider from A to B and also that same rider from B to A so although it is two trips but one rider. So halving the ridership for comparison to overall population yields a ~40% ridership, still unlikely. But lets work with it. 2)By dividing Daily Passenger Miles by Daily Passenger Trips a 4.23 mile average trip per rider is calculated. Completely feasible. 3)Accepting the given $.33/per passenger mile and multiplying the 2) results (4.23 miles) a $1.40/trip average is found. Confirmed table 3. 4)Multiplying 3) by the Daily Passenger Trips; MTA spends nearly $9.02 million a day...or $3.39 billion a year in expenses. Not far off from that given. 5)The fee per subway ride, according to MTA is $2.50, so MTA receipts are $16.1 million/day or $5.8 billion/year...WOW! 6) Are you suggesting MTA nets $2.58 billion/year? Or could it be the given stats are...curious? I never suggest NYC was the world capital for mass transit efficiency. In fact quite the contrary. The US transit system are wrought with bad practices and outdated designs. Europe, Shanghai, Taipei...etc have all modernized their trains. The US, however will never take such steps do to the intrenched interest. Tom there is a lot of money to be made in these government approved entities; unlikely to change. Tom, I still owe you a response to 35. There is much in that post I need to consider. -
Tom Curtis at 16:28 PM on 4 June 2011Are you a genuine skeptic or a climate denier?
Camburn @296, you may never go to denier sites but I suspect you simply never notice how libellous and abusive is the language directed as pro-science participants in denier forums. With regard to the word denier, it does not have the associations you purport it has. I was aware of the use of the term to describe those irrationally opposed to taking action on climate change for at least six months prior to connecting it in anyway with the holocaust. That connection was only made because some deniers where insisting that it was the intended connection in its use, an accusation I find bizzare. For the record, in calling somebody a denier I no more wish to associate them with holocaust deniers than I wish to associate them with 911 deniers, moon landing deniers, birth certificate deniers, or evevolution deniers. I no more wish to suggest that AGW deniers secretly admire Hitler than I wish to suggest that they are sexually inadequate. The fact is that "denier" is a common word for people who hold rationally indefensible positions which are not kept open to refutation by contrary evidence. That it has famously been used of holocaust deniers does not change that meaning one iota; and suggesting that any use of the word is an attempt to create an association with nazism is an attempt at censorship. If there was anything in your charge at all then I would have to conclude that you have deliberately associated yourself with right wing, racist supporters of nazism by calling yourself a skeptic, for those righ wing racist nazi sympathizers call themselves holocaust skeptics. With regard to Hansen, I have defended Hansen at length already on this thread. So unless you wish to clearly state spreading disinformation that results in thousands of deaths in the full knowledge that it will probably result in thousands of deaths is not, and/or should not be a crime, I just have to chalk you up as another denier misrepresenting Hansen. Finally, you claim to be a skeptic, not a denier. Well the evidence I have seen makes me skeptical of that claim, but the proof of the pudding, as they say, is in the eating. If, indeed, you are a genuine skeptic it will not worry you that you are called a denier - you'll just get on and argue the science. After all, I have been called an irrational left wing radical who is only arguing for the consensus position because I am a paid Labor party troll and because I only want to fraudulently secure more funding for my fraudulent research, and because I secretly want to engineer the deaths of three quarters of the world population. But it is not that, but the lack of evidence from the deniers that concerns me.Response:[DB] Tom elquently has made the case that the resistance to the term denier by equating it with Holocaust denial/Nazism/fascism/NWO is a patently transparent attempt to reframe the struggles of those espousing science vs those espousing non-science as a "debate" wherein it is possible that both "sides" may be right.
Since that is clearly not possible, can we all put an end to the references to Holocaust denial/Nazism/fascism/NWO? If one wishes to forego what the science and logic tells us is happening in the physical, measurable world, that is their right. But then the appellation "denier" sticks by default.

Very nice post. The land/ocean ocean proportion for the islands was a particularly nice piece of work. Nick Stokes revisted the 60 calculation question after he implemented area weighting in TempLS. Instead of picking them somewhat arbitrarily, he picked them to give optimal global coverage on the basis of the area weightings. The result is even more striking:(The post is here.)

There is a radical left in USA? It keeps pretty quiet. Policies I would associate with centre-left parties get labelled "communist" by US citizens. From media impressions, encounters with socialist Utopian dreamers from here or Europe would result in a National Guard call-out.

Tom Curtis at 261 - regarding social intelligence vs. critical thinking. GREAT POST! That is a very interesting way to think about the problem of denialism. One of my mentors has pointed out over and over and over that we will switch to a renewable energy system from peer pressure, and peer pressure alone. A fascinating example is happening in my little corner of the universe. The local electric monopoly is studying how much renewable energy its local substation can handle (going for up to 25% (all from distributed solar PV on rooftops). This will debunk the utility industry claim that 10% is the max you can handle on any given substation. My right wing neighbor finally threw in the towel and got solar. I will be very, very curious to see if this neighborhood goes even more solar after the test period, proving my mentor's point that peer pressure means much more than cold logic and analysis. This is the underlying logic of my oft-repeated "bias towards action" - but you are much more eloquent than I in stating the hows and whys. -

Garthman:"So for every extreme right wing believer, there will be an extreme left wing ideologue, for every barking mad right wing religionist there will be an evangelical atheist" I don't believe this is true. One point is that those on the left tend to rely on science and evidence, while those on the right tend to rely on faith (witness the creationism "issue", climate change denial, ignoring the fact that taxes pay for government (ie it is not true that cutting taxes increases funds for government services). In the United States, the "radical right" has created the tea party. The "radical left" (which I am often accused of being) - promotes the responsible reduction in fossil fuel use before it becomes a crisis (we are on the edge of this). I hope this is not too political. I think the point needs to be made - mainstream in the USA right now is very right of center, and the usual co-traveler of the right is a strong (and expressed) desire to ignore inconvenient scientific and financial truths. This has the potential to be very, very bad for all citizens. Not understanding the problem leads to trying to solve the wrong issue - like arguing over debt ceilings instead of balancing the budget, or arguing about whether climate change is happening, instead of focusing on solving the issue. -

Cumulative emissions, and historical share, are red herrings. The Chinese have used this dodge since 2004, to avoid accountability for practices since the nature of the GHG-pollution threat was understood. Claims that China is taking the lead in 'green energy' is misleading to the point of false - the Chinese have tapped every form of energy available to the max as their economy grows as double-digit rates. And if there's a rush to suppress the coal pollution in China - get read for another 90s as the aerosl reduction cause a global temperature surge similar to the end of the Warsaw Pact economies.

drbad at 13:55 PM on 4 June 2011CO2 – Some facts, figures and outcomes
While China is the world's greatest emitter of greenhouse gases (it took over that dubious distinction from the United States in 2006), the US ranks at the top of the GHG leader board in cumulative emissions since 1850, with the EU second. Between them, the US and the EU account for over 55% of cumulative emissions. China is a poor fourth at 7.6%, and India is further down the list at 2.2%. One of the more unfortunate aspects of dumping so much CO2 into the atmosphere is that for all practical purposes, it never goes away, i.e, "carbon is forever." University of Chicago oceanographer David Archer has stated that, "The climatic impacts of releasing fossil fuel CO2 to the atmosphere will last longer than Stonehenge, longer than time capsules, longer than nuclear waste, far longer than the age of human civilization so far."Response:[DB] Nice Archer quote.

Camburn at 13:47 PM on 4 June 2011Are you a genuine skeptic or a climate denier?
Tom: I guess I must never go to deniers sites, as I have never witnessed the type of language you are writing about. This is a two sided topic tho. By using the word "denier", you, or anyone else using it, bring violent thoughts to mind. The Holocost was horrific, with most people familiar with pictures etc of what happened. That, in and off itself, will create emotions that have no bearing on the arguement of AGW. When Dr. Hansen says CEO's of oil co's should be put on trial for high crimes against humanity, that also provokes images of the death penalty. This is not a one sided thing. The thing is, for anyone to make a threat against anyone else on a personal level, is not to be tollerated in any way shape or form. I am a skeptic in the truest sense of the word. When I look at paleo data of the Holocene, read papers from leading scholars such as Dr. Svalgaard, http://www.leif.org/EOS/2009GL040142.pdf concerning solar, look at radiation measurements etc....there is a puzzle yet to unfold. I am also a skeptic because of eminent people claiming that weather events are climatic events. Such as the case with the current level of tornadoes in the US. Yet NOAA sees no climate linkage at this time: http://www.esrl.noaa.gov/psd/csi/events/2011/tornadoes/climatechange.html Just a few tidbits. -
Camburn at 13:14 PM on 4 June 2011Of Averages & Anomalies - Part 2A. Why Surface Temperature records are more robust than we think
An NWP analysis is based on vastly more information thatn available from any single observing ststem. Data from ground, aircraft, bouys, ship, satellites, radiosondes, etc. are all combined to adjust the first guess field. As a consequence the quality of an analysis is much better than what can be obtained from gridding, or treating in other ways, data from a single or a few observing systems. To quote the 2nd paragraph of that link. So, being the quality is outstanding, we can compare year to year using the DMI data. From that one could get an anomoly to see if the warming/cooling is close to GISS data. As long as we are comparing the anomoly from 80 degrees north. -
Tom Curtis at 12:55 PM on 4 June 2011Are you a genuine skeptic or a climate denier?
A recent article on ABC online is relevant to my 138. In this case the death threats are not being directed at scientists in any way associated with climategate or any other faux controversy engineered by deniers, but at simple climate scientists. Some of the threats explicitly state that the scientists will be attacked "if they continue their research". There is a certain irony to this. Tallbloke, unhappy that a comment of his was deleted for containing a profanity, has posted a blog on his website about the supposed censorship at Skeptical Science. In comments he congratulates himself for the lack of inflammatory comments in his blog, but the blog itself begins by suggesting that John Cook is "scarily brief step" from locking scientists who disagree with the consensus on global warming away in mental institutions. Indeed, the form of that suggestion, a truncated paraphrase of Martin Niemöller's famous quote ("First they came for the Jews ..." indirectly associates Cook with Nazism. Nothing inflammatory about that, of course. Or at least, not in tallbloke's eyes. The irony is that while tallbloke is trying to beat up a statement that scientists disagreeing with the consensus are probably wrong into a revelation inclinations towards totalitarian suppression of dissent, his fellow travellers are using death threats to actually try and suppress dissent, and indeed, not just dissent, but research. This is not to suggest that tallbloke or any other well known denier would approve of such threats. Indeed, I am sure they would be horrified at the thought. But when you habitually accuse a group of people of fraud, conspiracy, genocidal inclinations, and, of course, suppression of dissent by totalitarian means, it would be surprising in the extreme if that did not translate into threats against those people. All of these accusations have been made by some well known deniers, and no well known denier has not make at least some of them. Including, of course, tallbloke with his nazi allusion. Anybody thinking the debate here sometimes gets a bit too vitriolic should bear in mind the nature of the accusations deliberately and publicly made by the most prominent deniers against the more prominent climate scientists. They should also bear in mind that probably not one active pro-science debater on this site has not at some time or another been accused of fraud, conspiracy to defraud for monetary gain, and intentions of genocide. I know I have (all three), and I am not even a climate scientist. These accusations are routinely made on denier sites whose participants laud themselves on their politeness and reasonable tone, while vilifying such sites as Skeptical Science for the abusive nature of the comments made here. This illustrates clearly that denialism never stays constrained. It necessarily infects all parts of a persons thoughts or else it will self destruct from inconsistency. -
Camburn at 12:24 PM on 4 June 2011Of Averages & Anomalies - Part 2A. Why Surface Temperature records are more robust than we think
It would be interesting to compare the anomoly of GISS to the DMI temperature data sets. http://ocean.dmi.dk/arctic/meant80n.uk.phpResponse:[DB] Digging a little deeper gives an answer to that:
"The temperature graphs are made from numerical weather prediction (NWP) "analysis" data. Analyses are the model fields used to start NWP models. They represent the statistically most likely state of the atmosphere, given the information available to make the analysis. Since the data are gridded, it is straight forward to deduce the average temperature North of 80 degree North.
However, since the model is gridded in a regular 0.5 degree grid, the mean temperature values are strongly biased towards the temperature in the most northern part of the Arctic! Therefore, do NOT use this measure as an actual physical mean temperature of the arctic. The 'plus 80 North mean temperature' graphs can be used for comparing one year to an other."
DMI presents us a tool; like any tool, it can be put to purposes other than intended. Like a direct comparison to GISS...

Not sure where you are getting your information Albatross, but the warmest years on record are all El Nino years; 1998, 2005, 2010. The opposite for La Nina. Where are the inconsistencies? I do not know what issue you have with the CRU scientists, but it is the longest running thermometer database. We have probably gotten a little OT, but ENSO does affect Amazon rainfall, so I would be willing to keep it to that. -

Eric (sk), your comment on flood adaptation was interesting to me. A large part of my institute works on identification and assessment of geological risk. We despair at local authority handling of this (despite planning laws that many US states I think would regard as draconian). We would love to see more private insurance involvement - ie insurers assessing risk before a development goes ahead so everyone knows up front about insurance risk. On other hand, your idea of removing levies sounds tricky. Landowners suddenly exposed and unable to get insurance are going to feel property rights were violated and surely they are in different category to those who knowingly bought property in a floodway. Good luck getting their votes. Better still - slow the rate of climate change so you dont have to do expensive adaptation. -

Another excellent and clear article Glenn. I like the way you can see all the cherry-pick arguments falling apart as you read through it. One quick typo, in the 4th paragraph from the end "... are less significantly less ..." maybe lose the first 'less'. As there seems to be some discussion about it, and I don't actually know the answer ... how does GISS treat summer Arctic temperatures? The holding of surface temperatures in summer to about freezing so long as there is ice cover is well known, and I might assume that GISS accounts for this, but maybe I'm wrong? It would not seem right if summer surface temperatures were extrapolated to be well above freezing far out over the melting ice. -

@Eric, The explanation: "Note that an isothermal melt period can be observed in the time series for each dataset when the SAT reaches the ice melt point. During this period the SAT is maintained at about 0C until all the snow and ice in an area have melted." The solution: "During most seasons, SAT trends can be studied by simple statistical methods, but during summer, because these masses hold the SAT to the melting point of sea ice, detection of changes in SAT must rely on other, less direct indicators such as the length of the melt season." -
ClimateWatcher at 07:46 AM on 4 June 2011Of Averages & Anomalies - Part 2A. Why Surface Temperature records are more robust than we think
Yes. Surface temperature trends (CRU: 1.5 K/century, GISS: 1.7K/century) are pretty close to (RSS LT: 1.4K/century, UAH LT: 1.4K/century, and sea surface: 1.3K/century)So we have some confidence in the trends, which we then observe are less than the IPCC best estimate for the 'Low Scenario' of 1.8K/century.
Moderator Response:[DB] What is the paternity of your furnished graphic?
[Dikran Marsupial] IIRC the projections have temperatures rising at an increasing rate, so an increase of 0.14 to 0.17 K/decade at the present time is perfectly consistent with a projected rise of 1.8 K/century. I suspect the projections have temperatures rising faster than 0.18K/decade towards the end of the century. -

Thanks Agnostic - a very informative post and a great place to send people who wonder what the fuss is about things getting a few degrees warmer. Thanks DB (and all other mods), once again. Pete - I believe that Hansen and Sato are speaking of the possibility of 5m by 2100: "BAU scenarios result in global warming of the order of 3-6°C. It is this scenario for which we assert that multi-meter sea level rise on the century time scale are not only possible, but almost dead certain." Pretty much everyone agrees that >10m becomes very likely on centuries or millennia timescales once Greenland and the WAIS pass tipping points that we may well already be close to. -

Eric @27, Sorry, but you are talking through your hat, and your observations regarding the impact of ENSO on global SATs are incorrect and inconsistent with each other. Ironic that the CRU global SAT dataset (made by those "cheating" scientists) is now the darling of the 'skeptic" crowd-- I wonder why (/sarc)? Might I suggest we move the discussion about the impact of ENSO on global SATs (yea, mea culpa) to a more appropriate thread, as this page is about the Amazon (a regional response). -
scaddenp at 07:00 AM on 4 June 2011Amazon drought: A death spiral? (part 2:climate models)
Eric- one needs to look at the change in temperature as function of the ENSO index. Have a look at Tamino's analysis where relationship with MEI and volcanos is factored in. In press I believe. -
scaddenp at 06:53 AM on 4 June 2011Are you a genuine skeptic or a climate denier?
Eric(skeptic) - whoops, you are correct. Confusing sensitivity with GHG forcing. You said " It isn't 3.7 W/sq meter for doubling of CO2" but now agree that it is? Again, my point here is that you appear to have beliefs without published science to back them. As coal-powered goods. I'm amazed (and encouraged) that you would even consider carbon-tariff. I was really asking whether you were so ideological driven that even if you knew that costs of mitigation where lower than cost of adaptation, you would reject any effective emission strategy. With that encouragement, what would carbon tariff look like that was acceptable? Do you think other libertarians would accept it if you also became convinced that emission-reduction was cheapest option? -
miklos treiber at 06:53 AM on 4 June 2011The Fake Scandal of Climategate
Show me the empirical data, methodology, and computer codes for any scientific argument you can produce and the truth will be known. If you persist in hiding the data, methodology and code, the work you have done is for naught. Without validation such work is only opinion at best. Predictions based on non-validated work is at best a guess.Moderator Response:[e] There is a comprehensive catalog of available climate data sources here. This site also makes extensive efforts to cite all claims back to the original research. If there is a particular piece of information you are looking for, please use the search function or peruse this site's list of skeptic arguments.
The surface temperature post may be of particular interest to you, as it discusses the multiple independent reconstructions and validations that have been done on the CRU and NASA data.

J Bob, not that interesting - ignores other forcings. Benestad and Schmidt is interesting. As is Tamino's but not published yet. -

Very interesting warm, While winter temperatures are somewhat correlated between the land and ocean, in the summer they found, "no correlation between the interior land and ocean observations." -

Pete Dunkelberg at 05:31 AM on 4 June 2011CO2 – Some facts, figures and outcomes
Thanks for assembling this. Lets note that this "... Hansen and Sato predict a rise of up to 5m." is not really a prediction of the high end. Unfortunately, under a business as usual scenario, there is no reason why sea level can't go up that high. In fact it is very likely to, but how soon? Unfortunately this can't be determined yet. By the way, if you are looking for consequences here's one. -

Dr PhD, I suspect your perception of hostility is due in part to your assumption that some demonstrably highly knowledgeable individuals are simply unaware of really basic things. And, your last response indicates an unawareness that Dana is not advocating 100% solar and/or that there exist ways of storing energy for later use. Do we have such capacity to store energy on industrial scales now? No, but it is an engineering problem and I have more faith that it can be solved than the problem of fusion or some other miracle cure will be found. Personally, I don't know and don't care if nuclear is required. Compared to the costs/effects of widespread food shortages, an incident like Fukushima every decade or so is a fair trade-off. Chernobyl like situations are to be be avoided, of course. My guess is that fast-breeder reactors are a viable course for base load, but nothing is going to be as expensive as continuing fossil fuel use. It is likely that Camburn is right that the US will not implement cap-and-trade anytime soon, and I prefer a phased-in carbon tax+dividend anyway, but that does not mean that the US and the world at large would not be better off if some attempt to limit CO2 production were made. For instance, if a disastrous harvest in Russia can spark a wave of revolts across the Middle East, I'm not looking forward to seeing what a serious drought across the agricultural regions of China triggers. China will just buy up whatever their shortfall is, but that won't be good news for whichever poorer nations have to bid against them. If it happens that the US has a poor harvest at the same time, I don't know that the US could get away with an export ban as Russia did; China has leverage on the US because of debts. It is a pretty safe bet that food production will suffer some impacts in a BAU world. Here is something recent: Mapping hotspots of climate change and food insecurity in the global tropics -

To further your parallel resistance analogy. If your circuit is powered with a 240 W sources, how many resistors, any arrangement of your choosing, are required to increase the supply power to 390 W? -
Dr. Jay Cadbury, phd. at 04:21 AM on 4 June 2011Renewables can't provide baseload power
Okay so to better understand my opinion, I'm a big free market guy, believe the market is self-correcting and finds its own solutions. When I look at global final energy consumption and I see alternatives contributing between 0-1%, I'm not optomistic. I firmly believe there would be a car running on solar if it were cheaper but I don't think it is. I think we might find that fossil fuels are permanently cheaper than alternatives because of the massive potential in gas hydrates.Response:[dana1981] My moped runs on solar energy. A lot of peoples' cars run on solar energy, too. I'll be one of them in a few years. Fossil fuels are already more costly than renewable energy, and that includes coal. Try reading the Renewable energy is too expensive rebuttal. Right now the "free market" doesn't take into account the full costs of fossil fuel energy. Not even close. Economists hate it - it's a market failure. That's the point of a carbon price, to make the free market work better.

Dr. Jay, PhD: I like wind and solar but everybody besides dana knows that at night the sun is gone and there is a moon and the wind is not always blowing. The hostility, such as it is, arises from the fact that you don't seem to know what you're talking about. In the first place, storage systems already exist for solar energy. You can try googling "thermal storage." Or if that's too technical for you, "batteries." Are these solutions perfect? Obviously not. Is there no conceivable way of improving them? Obviously not. Are companies working on these problems right now? Of course. Beyond that, the complaint that "I don't see 100% of our energy needs met with renewable energy" is basically a strawman, as well as an example of the fallacy of exclusion (i.e., it implies that we can meet 100 percent of humanity's energy needs with nuclear and fossil fuels. Which is debatable, to say the least). It's also funny that the people who whine about the practical availability of renewable resources tend to be downright cornucopian about our supply of fossil fuels, but that's a rant for another day.Moderator Response: A better thread for continued discussion of this topic (if Dr. Jay chooses to reply) is Renewables can’t provide baseload power. -
Charlie A at 03:22 AM on 4 June 2011Can we trust climate models?
Kevin C, you may find the following article from International Journal of Forecasting interesting as it uses a variety of metrics to compare the HadCM3 AOGCM of Hadley center with some time series forecasts. Validation and forecasting accuracy in models of climate change Non-paywalled draft paper Discussion and additional info from author at Pielke Sr's blog. When looked at from the point of view of a statistician or forecaster, the climate models don't do very well globally, and are very poor at regional predictions. The climate models, in many tests, have predictive capability worse than a random walk. -
David Lewis at 02:57 AM on 4 June 2011Climate Change Denial book now available!
RE: my earlier reference to Public Radio International's "Living on Earth" March 25 2011 interview with Amory Lovins, which I said illustrated my point that Lovins operates in a similar manner to Lord Monckton. The interview is still there, i.e. http://173.236.147.250/shows/segments.html?programID=11-P13-00012&segmentID=2 but it seems that "Living on Earth" has now removed all comments from their shows and no longer allows them. My point expands a bit, from why do opponents of nuclear power have to lie if the case against nuclear is so strong and clear, to include, why do shows caught airing the lies have to censor people who comment who point out that the lies exist? Its something for an author who studies how and why climate science deniers operate who argues against nuclear power the way you do, to think about, I think.
