nigelj at 09:17 AM on 3 October 2017Why the 97% climate consensus is important
Good article thanks. Consensus is vitally importantant, and we need to know about the consensus. Clearly over 90% of scientists agree we are altering the climate from various studies, and this alone is obviously important, and at least in that it should be getting our strong attention or we are idiots.
Nothing good comes from hiding information, at least not from adults.
This is partly why consensus is important as follows. Consensus at least gives us an indication of where the general thinking is going, and what is most likely to be the correct answer. The general public often struggle with scientific detail and obviously dont have the time to read the detailed science. As a result the first question many people ask is what do the experts think? The general public do this, politicians do this. As part of this process its important to be sure we get the thoughts of a wide range of scientists, and particularly the consensus view. We don't want to be listening to just one dissenting sceptical voice, not realising that voice may be in a minority. We need context, and dont want to get fooled into thinking opinion is divided if it isnt.
If the majority of scientists agree on something, that is cause to at the very least pay attention, while a 50 / 50 split would suggest more work is needed. But it also depends on how serious the threat is, because a very serious threat (like an asteroid heading our way) might suggest even a 50 / 50 split of opinion on the matter should still suggest precautionary action is desirable.
I disagree with the view by Pearce in the Guardian that publicising the consensus view is counter productive. Only had time for a quick scan through the article, but straight away he bases his view that we don't need to publicise the consensus because reasonably good numbers already think climate is changing, its a problem, and we should do renewable energy . Those are correct figures, but omit the fact that only low numbers in America think humans are causing climate change. This is very significant, because this line of thinking will colour the totality of our response to climate change. And the consensus goes right into causation.
However Pearce makes a good point that arguing too much about the exact level of consensus is a waste of time. Ideally we want more awareness of the consensus in the general media, but to avoid getting bogged down to debating exact numbers too much, etc etc.
There are indeed a whole lot of other things to focus on as well as others point out. I agree with JW Rebel the challenge is around dealing with responses and uncertaity of outcomes etc. One thing that may help is much more specific information on how much transitions to renewable energy will cost the averagre person per year in dollar terms (and the data suggests not actually very much). Right now the numbers on this are not front and centre of debate, and are quoted in terms of gdp, which half the population don't even understand or find hard to visualise. Lack of clear, simple information creates uncertainty and fear.

"It just confuses the people you are trying to convince."
It only confuses people who do not want to be convinced. Anyone who even reads a little bit of the accurate and honest information out there, not the dishonest stuff from well known AGW denier sites, will not be cofused with the things you claim to be confused about.

“Energy subsidies are projected at US$5.3 trillion in 2015, or 6.5 percent of global GDP, according to a recent IMF study. Most of this arises from countries setting energy taxes below levels that fully reflect the environmental damage associated with energy consumption. “

JWRebel at 06:43 AM on 3 October 2017Why the 97% climate consensus is important
Pearce's line of argumentation is not being completely represented here. He is not trivializing or belittling the important contribution that consensus awareness can make, nor stating outright that there is nothing left to accomplish on this score, but stating that public discussion about the exact method and numbers to establish consensus accuracy can divert attention into politicized discourse that detracts from a much more urgent question, viz., how to get more support for policy measures. Better consensus awareness does not necessarily lead to more preparedness to support the needed policy measures (e.g., carbon taxes), and how to fuel such motivation is a trickier and more urgent question. The 97 number can become a fetish, depending on precisely which question is being analyzed. The fact that there are no creditable attempts at explaining comprehensively the many lines of evidence speaks to me like 100%.
In terms of policy measures, the uncertainties with regard to outcomes is obviously much greater than the basic science about the problems we face. Overcoming that uncertainty in order to still get something done is a challenge of a different order, and one not addressable by science alone: it is more akin to persuading someone not to light up that next cigarette, knowing that one cigarette less is not exactly a matter of life or death.

#38 - The broader point on the fossil fuel subsidies - is that most of what is labeled as subsidies by various advocacy groups, etc are simply not subsidies by any economic definition. Many of the so-called "tax subsidies" are tax deductions for the cost of doing business. Additionally many of the so-called "tax subsidies" are deductions which are allowable to all industries and are not subsidies carved out to benefit the fossil fuel industries.
There being two exceptions - percentage depletion in excess of basis which only applies to royalty owners and independent producers. (US title 26 section 613A). Second , the deduction for IDC which that subsidy reverses itself in subsequent years and becomes a negative subsidy and which after a period of years becomes an net wash. See for example most any of the majors annual report, where the annual DDA generally exceeds the net oil & gas properties current year additions. (the majors will use either successfull efforts or full cost accounting whereby the idc is capitalized for GAAP purposes, and amortized over the life of the properties).
In summary, most of what the advocates characterize as subsidies are non existent or greatly stretch the true economic definition of a subsidy.

I respect you may have some expertise on fossil fuel financing, but I can't help but think you are missing the point on fossil fuel subsidies. Fossil fuels are subsidised. The exact level is hard to be sure of, but doesn't matter. None of the subsidies make much sense in terms of genuine economic justification. They certainly dont make sense in the era of climate change. End of story.

A) you cited an article from an advocacy website, even individuals without expertise should be able to recognize the bias.
B) The errors are readily apparant to anyone with a basic level of taxation
C) my explanations, coupled with a basic knowledge of accounting, should be sufficient for most individuals to quickly grasp the errors.
You state that you rely on experts, though it should be pointed out, that experts wouldnt make such glaring errors.

"Armed with the knowledge of the tax policy definition of "revenue neutral", it should now be apparant why a wealth transfer from an efficient producer to an inefficient producer is not revenue neutral - If the receiver of the subsidy was efficient, it would not need a subsidy."
With respect you clearly dont understand the legal definition of revenue neutral. The only thing that counts is whether theres a significant change in government revenue, nothing to do with "efficiency". This is clearly the view of the politiicans involved in the matter from the discourse I have read. None of them are talking about efficiency in the way you are in relation to the fee and dividend idea.
You also continue to fail to understand the recepient is not inefficient.
You also fail to understand the reasons for subsidies. Efficiency is not the criteria on which subsidies are properly based. Subsidies are properly used wheren there is some public benefit and / or to encourage new enterprises to get started, when the enterprise is desirable, but faces market difficulties. Therefore it is legitimate to subsidise inefficient industries in their formation period. This includes some elements of renewable energy notwithstanding some of these are efficient, and some less efficient at this stage.
It is not sensible to subsidise ongoing profitable companies because they dont need help, and it would not be possible to subsidise all such companies even if you wanted. This is why its doubtful that its sensible to subsidise fossil fuel companies. And they currently receive all sorts of subsidies. The only possible reason might be a subsidy for the risks of exploration, but given how profitable the companies are, even this doesn't make much sense. And given climate change, there is now no reason to subsidise fossil fuel companies left at all. Its complete madness to continue to subsidise fossil fuels on the one hand while for example having renewable energy subsidies and cap and trade on the other.
The following link will give you some brief indication of how subsidies have been used historically, and when they are properly used for good purposes, especially helping new companies get started:

Tom13,
I do not claim expertise at tax accounting, I rely on experts to provide summaries like the one referenced .
You have demonstrated your level of expertise by being unable to locate the data in the appendix of the report and claiming that it was "A 103 page report and virtually no info on what the actual subsidies the fossil fuel companies receive." The appendix was cited several times in the report as containing the data. Please provide a citation of an expert to support your wild claims.

"As noted by Vecchi, there has been little to no discernable difference in ACE after adjusting for observational limitations since the late 1800's"
Its always difficult reconciling your statements with the sources you then quote. You seem to have it wrong. Maybe Im missinterpreting it, but your link says the following and people can make up their own minds.
"The sensitivity of North Atlantic tropical cyclone frequency, duration, and intensity is examined for both uniform and nonuniform SST changes. Under uniform SST warming, these results indicate that there is a modest sensitivity of intensity, and a decrease in tropical storm and hurricane frequencies. On the other hand, increases in tropical Atlantic SST relative to the tropical mean SST suggest an increase in the intensity and frequency of North Atlantic tropical storms and hurricanes."
"The second point is that using a single data point - such as the month of Sept 2017 will most often lead to erroneous conclusions."
I agree.
"the noaa, geophysical fluid dymanics lab frequently mentions that lack of any discernable differences in ACE."
But the following source says the intensity of N Atlantic hurricanes has increased. I guess its just a contested issue, and only more and better data will fully settle whats happened historically.

Michael - Try to actually refute the points I made. As I previously stated, the errors in the report are obvious for anyone with knowledge of oil and gas taxation. I have limited my comments to US oil and gas taxation which is where my area of professional expertise.
Just two examples of the errors is the first line listing MLPS and a tax subsidy of $3.931B. Its difficult to claim a tax subsidy in an enviroment where the MLPs have been showing net losses, the majority of which have in both 2015 and 2016.
The second example is the LIFO being claimed as a subsidy. Lifo reduces the tax liability in an inflationary market, but results in greater tax in a deflationary market. 2014 was the year of the drop in oil prices from $100 per bbl down to the $40's, yet the report shows an increase in the tax subsidy from $857m to $1.152b. That is mathematically impossible.

tom13,
You are apparently an expert on everything since you always rely on your own intpretation and never cite expert opinion.
You should be forced to cite experts for your claims since this is a scientific blog. You are only a denier who is too ignorant to understand expert evaluations and think you know better than everyone else.
Hopefully all the other readers here will dismiss your claims since you obviously do not know what you are talking about.

Michael - Thanks for the link.
www.odi.org/publications/10086-g20-subsidies-oil-gas-coal-production-united-states
The errors in the computation and logic of the data provided are easy to stop - at least for those with knowledge of oil and gas taxation. Lets start from the top
1) corporate tax exemption for MLP's - A) the income tax is being paid at the individual partner level, instead of the corporate level, net result is a small reduction in tax paid. B) The $ amount of tax subsidy is show as $3,931 for 2013, 2014 and 2015. Using the same $ amount for the three years belies reality. With declining oil prices, most of the MLPs are lost money, especially in 2016.
2) IDC - intangible drilling costs - this is a deduction for the cost of production, Secondly, it is only a timing difference. In year 1, there is a tax deduction, year 2-year 10, there is no deduction, in other words, after a few years, the deduction/benefit becomes a wash, so no net "tax subsidy.
3) domestic manufacturing deduction - Every manufacturer receives this deduction, - it is not unique to oil and gas.
4) Lifo inventory - Lifo only saves tax money in an economy when prices rise. Oil prices are by their nature volatile. Quite frankly absurd that lifo is treated as a subsidy, more absurd is the computation.
5) Percentage depletion in excess of basis - granted this is the only true subsidy - however, it only applied to royalty owners and independent producers. The computation of the amount is obviously incorrect. They have computed the same $ amount for all years even though prices have dropped which would reflect lower depletion allowable.
I just pointed out the first 5 obvious errors.

Tom13,
I went to the linked report. It has appendices that contain all the specific data for the subsidies. You have simply not read the part of the report that you claim is missing. Here are the first 6 lines of over 119 from an Excell spreadsheet that document USA domestic direct subsidies. (to access the data go to the report, click on the appendices and then direct subsidies for the USA)

It is your responsibility to read the reports cited. When you claim that the report does not contain information it actually contains, that makes your argument weaker. In the report they sumarize the data because the data take up too much space to repeat everywhere.
Your claim "I do not believe this report" is simply false, you have not done your homework. You often do not do your homework before you make wild claims.

magellan @2.
I assume you are asking about the OP item "September is the most energetic month for hurricanes ever recorded in the Atlantic" and asking 'Most energetic since when?' (By the way, I am not aware of any new sovereign state being formed in 1776. I would guess the date you should be quoting is 1781.)
September 2017 saw Atlantic hurricanes for the month top the Accumulative Cyclone Energy (ACE) record set in September 2004 (ACE=155) with an ACE value for the full month of ACE=176. While historical tropical cyclone data in the Atlantic is more complete than in other ocean basins, it is still subject to inaccuracy prior to the satellite era, pre-1970s. However, with the data available it is possible to say that the ACE=176 for Sept 2017 is certainly the most energetic since before 1950, there being no other month that comes close to that value since then.
As far as the 2017 hurricane season so-far, it has racked up ACE=202 by the end of September and for the time-of-year sits in second place (1950-to-date) behind the 2004-season-to-the-end-of-Sept (ACE=220). It is possible this is =2nd as 1950 is not far behind. 2017 has so-far topped the ACE for all complete years bar five back to 1950, and bar eight back to 1850. This is set out graphically here (usually 2 clicks to 'download your attachment').

#27 - A 103 page report and virtually no info on what the actual subsidies the fossil fuel companies receive.
Page 68 mentions the reduction of the severance tax on oil & gas produced in Alaska - Severance tax is a tax that only the owners of the oil and gas properties (and other mineral and mining interests) incur. No other industries are subject to this tax. A reduction in a tax that is only imposed on a few is not a subsidy, but instead a reduction of a wealth transfer.
P 82 - The article calls the tax deduction for the cost of operations a subsidy. All industries receive tax deductions for the cost of operations - so by that articles definition, every industry receives subsidies.

Armed with the knowledge of the tax policy definition of "revenue neutral", it should now be apparant why a wealth transfer from an efficient producer to an inefficient producer is not revenue neutral - If the receiver of the subsidy was efficient, it would not need a subsidy.

jgnfld at 20:20 PM on 2 October 2017Climate and energy are becoming focal points in state political races
The "tragedy of the commons", which is what is at base here w.r.t. the harm fossil fuels cause the globe, is a clear example of market failure. I'm not sure it's useful to talk about this failure in terms of "subsidies" and "wealth transfers", however.
A small group can exploit a large resource with impunity. However once the exploitation is at a level that all are affected negatively while at the same time there is no clear market feedback to those exploiting the resource, a crash is a typical outcome.
The fossil fuel age is presently exploiting the atmosphere beyond its abillity to stay in a safe range. If there are no market feedbacks that producers and users directly feel w.r.t. staying in that range, a crash of some sort is pretty much inevitable. Hopefully one that can be accommodated to a great degree.
We don't want a crash to occur with the climate, really, any more than we want collapses of any critical common resource. Even our most libertarian-spouting commenters should realize that. (There is a libertarian literature on this point, but freshmen libertarians tend not to be aware of it.)

Tom Curtis at 20:04 PM on 2 October 2017Ivar Giaever - Nobel Winning Physicist and Climate Pseudoscientist
magellan @90, before Darwin went to Cambridge, he studied to become a doctor for two years at Edinburgh. While he neglected his formal studies, he hung out with scientists, and most of his extra curricular studies was in biology. He was a member of the Plinian Society, and a regular companion of Robert Edmond Grant, a biologist. It was at the Plinian Society that he made his first two original contributions to science, both in the field of biology.
At Cambridge, he again neglected his formal studies, but became closely attached to a group of scientists. The closest of those attachments was to John Stevens Henslow, who was best known as a botanist. The attachment was so close that Darwin's nickname at Cambridge was "he who walk's with Henslow". It was on Henslow's reccomendation that Darwin was offered a position on the Beagle.
Darwin's interest in geology came late at Cambridge, and mostly consisted of a walking tour of Wales with Adam Sedgwick. That education in geology was expanded on by reading Lyell's "Principles of Geology" while onboard the Beagle.
As you can see, you have the facts regarding Darwin exactly reversed. It was biology that he had more extensively studied when he first came on board the Beagle, an area in which he had already made two, minor discoveries. It is unlikely that his late interest in geology would have much influenced Henslow's recommendation, given that the recommendation was made while Darwin was still touring Wales (and hence before Henslow could assess what he had learnt thereby).
This is often forgotten because Darwin's most initially celebrated accomplishments were in the field of geology - first in the form of a detailed description of the effects of an earthquake on local sea level in South America, and then, most famously, in his description of who coral atolls are formed, and what explains their distribution.
But following those acheivements, he was heavilly involved in classifying his biological finds; and then published a major contribution to biological systematics in two volumes before turning to witting The Origen of Species.
Your argument would be better if reversed, but even then it would be wrong, for by the time Darwin made his geological contributions, he had accompanied Sedgwik on the tour of Wales (as a result of which, and possibly other tours, Sedgwick discovered the Cambrian); and read Lyell's Principles while carefully comparing those principles to geological phenomenon around the world. -
MA Rodger at 19:50 PM on 2 October 2017Temp record is unreliable
The recent discourse about absolute global temperature appears to have ground to a halt but one aspect of this remained unmentioned and it might be appropriate to introduce it now - the Berkeley Earth temperature analysis. I was mindful that BEST would overly-complicate things for that enquirer. Yet as Rohde et al (2013) says "The Berkeley Average analysis process is somewhat unique in that it produces a global climatology and estimate of the global mean temperature as part of its natural operations." Thus mean absolute temperatures are to hand from the BEST data.
As a result, not only does BEST graph its global land temperature record using absolute values, it also provides within the data the absolute mean value of the anomaly base used (1951-80) for individual months and annually, the annual value being +8.7ºC. But this isn't entirely the end of this story.
Regarding the Land Only record, Rohde et al state "The global land average from 1900 to 2000 is 9.35 ± 1.45°C, broadly consistent with the estimate of 8.5°C provided by Peterson (et al 2011)." So the +8.7ºC value in the BEST data is a little different in Rohde et al. Further, this 8.5°C Peterson et al value is only re-quoted by Peterson et al, the value being taken from an NOAA FAQ table (on the 'mean temperature estimates' page), itself based on New et al (1999). Yet the true Global Land average temperatures are far far more dependent on local factors than the anomalies are. (Consider altitude - the average land altitude is 840m thus some 5ºC cooler than a sea-level average would be).
Note that while there are two different anomaly base periods in play here, the difference between them is tiny. The 1901-2000 mean is cooler than the 1951-80 mean by just 0.024°C in NOAA, with an almost identical tiny difference in BEST Land (and also BEST Land&Ocean).
Yet, while BEST Land temperatures may produce a global land absolute mean temperature "as part of its natural operations," that is not so clear with its Ocean data.
When combined with its Land Temperatures to create a full global Land&Ocean temperature series, BEST still provide the absolute value of the anomaly base (1951-80) within the data, that value being +14.720ºC or +15.305ºC (dependent on treatment of sea ice). Sea ice aside, the derevaton of an absolute value for SST is mostly trivial compared with the Land exercise. So if the quoted Land anomaly value of BEST & NOAA land temperatures is very close (+8.7ºC and +8.5ºC respectively) why are the global Land&Ocean values so different (+14.7ºC/15.3ºC and +13.9ºC respectively)? (And without an answer, this may have seen our recent enquirer running away shouting "I told you so!")The SST data used by BEST is HadSST3 but the documentation on BEST's use of HadSST3 appears a little sparce. HadCRUT4 also uses HasSST3 but their average global mean anomaly value is roughly the same as NASA/NOAA and lower than BEST (although note the source of this HadCRUT4 data similarly give a BEST Land value as +9.17ºC).
So no answer is apparent to me. Yet, whatever its cause, the discrepancy makes not a jot of difference to the anomalies in the various SAT/SST records which are unaffected by anomaly base values and provide global temperature records that are pretty-much peas in a pod.

Magellan @90 , it is a strawman argument to say that: "Ivar Giaever is not fit to address the issue because its [sic] not his field of expertise". And I'd love to know who are the "very smart people on both sides of the isle [sic] here". And which island are you referring to?
Magellan, you entirely miss the point about criticism of Giaever. It is irrelevant which "field of expertise" he previously came from.
Giaever's incompetent assessment of climate science is being criticized because
(A) He got it wrong. And got it wrong bigly !
(B) He had the hubris to think that a few hours of googling the topic of climate science would gain him enough knowledge to make a worthwhile contribution to the public discussion.
(C) He had the arrogance to think that a few hours' reading on non-specialist websites would qualify him to declare that all the experts were wrong.
(D) At the age of 83 , he had the chutzpah to lecture a formal gathering of Nobel Laureates (and also of many bright young scientists) about how science is done properly — while at the same time demonstrating his own failure to think logically about science! What an embarrassing performance in front of the young scientists (not to mention in front of the Laureates). Truly cringeworthy stuff !
(E) And he had the lack of insight to recognize the above.
~ Magellan, possibly you do not recognize/comprehend Scaddenp's euphemism of "Gone Emeritus" about Giaever. "Gone Emeritus" is a term used about some retired professors or retired eminent scientists — it represents a pathological fusion of hubris & mild senile dementia. It shows itself as wacky beliefs and/or a maverick's disregard of the evidence base of mainstream science.
If Giaever were 50 or 60 years younger, then scientists would simply call him a silly young fool. Yet still have some hope that he would come to his senses as he got a bit older.
Magellan, possibly you are not aware of the insidiously corrupting effects of small amounts of money or other inducement. Money etc that Giaever receives from propaganda organizations (e.g. his payments from the Heartland Institute in his role as an apologist for Big Tobacco) might not appear to you as very much or very likely to influence a famous/wealthy person to any great degree. But psychologists' experiments show that a small amount (such as $25,000*) can be more effective than a large amount (say $500,000) in maintaining & entrenching a person's adherence to a particular line of thinking. So for rather small amounts, the propaganda paymasters get very good value for money!!
[ * I mention this figure because it is an example: of a sum paid to the science-denier Richard Lindzen by Peabody Energy. I have not seen the size of the payments / stipends / gratuities / subsidies received by Judith Curry or her like, from paymasters such as Heartland, the GWPF, or under-the-counter industry slush funds. ]

Tom13 - to test "economic efficiency", are you prepared to support complete removal of all tax-payer subsidies from the fossil fuel industry? Starting with direct producer subsidies.

Tom13 @25,
"No its not revenue neutral - wealth transfers are never a zero sum game, especially with the transfer is from efficient sectors of the economy to less efficient secotrs - basic economics 101."
I think you are mostly wrong about that.
"Revenue Neutral Law and Legal Definition. The term Revenue Neutral implies changes in the tax laws that result in no change in the amount of revenue coming into the government's coffers. In other words, a tax proposal is revenue neutral if it neither increases nor decreases tax revenues when compared to existing law."
definitions.uslegal.com/r/revenue-neutral/
The tax and divedend idea does not increasing tax or decreasing tax by this definition. The claim that the fee and dividend idea somehow allegedly sends a subsidy to allegedly less efficient energy producers is therefore clearly irrelevant and another issue entirely.
Certainly the sheme is revenue neutral enough and nit picking about the issue becomes foolish. It should be acceptable to fiscal conservatives etc.
And as I pointed out you are incorrect to claim wind power is less economically efficient or that electric cars are less economically efficient, in fact electric cars are more economically efficient after about 5 years of ownership. And as I pointed out your definition of economic efficiency is far too narrow as it fails to consider long term environmental costs. So your assertion fails these tests as well.
There is also the point that if the subsidy on renewables could be funded by removing a subsidy on fossil fuels. This should alleviate concerns some people have about additional subsidies, and is also obviously revenue neutral in the sense that funding simply swithches from one thing to another that we want more of, which is renewable energy.

scaddenp at 07:08 AM on 2 October 2017Ivar Giaever - Nobel Winning Physicist and Climate Pseudoscientist
magellan. The amount of domain knowledge required to make a contribution to a field has gone up exponentially since Darwin. While it is indeed possible for people to make contributions outside their field, it takes considerably more work than 1/2 a days googling. The criticism of Giaever is not so much that he is outside his field, but - as demostrated above if you read the article carefully - that he didnt bother to gain any the requirisite background before making uninformed remarks.
The standard in science for making a contribution to a field, is to publish new insights in a peer-reviewed journal. Instead he is trying to make statements from an authority position (that he doesnt actually have), in support of an ideologically-driven agenda (ie his involvement with Heartland). In science palance, he has "gone emeritus". Not the first and wont be the last.
I have no time for ideologically-driven thinkers of left or right. Thinking that goes from " Proposition A would require Action B which is contrary to my political values; ergo Proposition A is wrong" is demonstrating the failure of education in critical thinking.

I am about to spend about 10 hours on planes (to Europe) and I have brought along Chapter 9 of IPCC 2013 (Evaluation of Climate Models) & Chapter 10 of 2014 IPCC on Mitigation Potential and Costs. Nigel I am trying!
Do not have time to respond re measurements but it is confusing to the layman. I am sure international shipping and aviation have agreed on what GPS system they will all use. I appreciate somewhat why anomalies are charted rather than absolute temperature changes but you lose the average person when you do so.
If the purpose of the climate research is to influence public policy then it has to be understandable to the politicians and the general public.
Getting some agreement on baselines seems to me to be absolutely basic so we are not always arguing about the basic facts. Just as a recent example, the Millar et al paper gets criticized for using HADCRUT rather than some other one which included the Arctic. Why do we have this? It just confuses the people you are trying to convince.

"Its a surtax, subsidy and a wealth transfer program precisely because the receiver of the subsidy is less efficient than the one being charged the surtax. Simple economics 101"
Yes its a surtax and a subsidy and wealth transfer if you like.
Its also revenue neutral, well justified, sensible, practical, and well targeted.
There is nothing wrong in principle with subsidies, and even orthodox economics recognises they have their place to encourage new industries of clear value that would otherwise struggle due to adverse conditions. All subsidies are a form of wealth transfer, just as the very concept of government itself and all its parts is ultimately funded by a wealth transfer of some sort.
And as has been pointed out, if renewable energy subsidies go along with cancelling fossil fuel subsidies, then things balance out nicely. There is no net wealth transfer.
Regarding efficiency, we are not transfering wealth to economically inefficient energy sources because wind power is now profitable even without the subsidy. This has been pointed out to you a dozen times, with numerous studies on costs but you still dont get it, - or wont get it.
If you are talking solar power maybe this is not yet quite profitable as a stand alone thing yet. But how do we really measure economic efficiency? We have to look ultimately at full costs and benefits much longer term, including environmental costs and health costs. In that sense renewable energy is more efficient.

We should discuss problems when they are current and fresh in peoples minds. We will be no use to anyone otherwise. Alligators and swamps.
I can't recall what really started the conversation on Curry. The concern is with the way she makes vague, often petty, and frankly silly statements that feed the denial machine, and are jumped on by politicians eager to downplay climate change, as people discussed in depth, with quotes from her writings. You should read the quotes and study them.
She may have got some hurricane prediction right by chance or skill. I'm not doubting her basic qualifications, just interested in why she has become a climate denialist, and why she makes the most incredibly obtuse, open ended and frustratingly vague and factually incorrect or incomplete statements. If that impresses you and rocks your world, I suppose you should read her "blog".
If she is paid by oil and gas companies it doesnt matter for what reason, there will be a perception of bias at the very least. If she wants to be taken seriously she might consider that.
Good to see you staying away form the Heartland Institute. Possibly avoid the more extreme environmental websites as well. Go straight down the middle with the IPCC. Their science is more than worrying enough.

I believe there are very smart people on both sides of the isle here, however I believe there's some missing logic on the global warming side.
I have seen the statement that
Ivar Giaever is not fit to address the issue because its not his field of expertise.Is it true that science has such a standard? Can a person with extensive knowledge in one field dabble in another's? Is it even possible that he may have an opinion that becomes the authority in another field of expertise? Sure, if we are all prepared to change our minds on Darwin.
Charlse Darwin was not a doctor, biologist, zoologist, nor veteranarian, but an expert Geologist. Now are we going to throw out 100 years of internal medicine over our bias?

Bob Loblaw at 03:23 AM on 2 October 2017Climate and energy are becoming focal points in state political races
Yes, Tom13, I can accept that you call that a subsidy. And with that definition it would be a subsidy when we do that for fossil fuels, too.
For pencil wood, if producer A has to grow trees or buy them from someone who grows them and pays all the environmetal costs associated with growing them, they'll pay the costs. When producer B gets government-owned trees free for the taking, where government pays for replanting seedlings, all the envrionmental costs, etc., then company benefits from a subsidy. Company B nenefits from a transfer of wealth form government to its shareholders.
That you think ending such subsidies for the fossil fuel industry represents creating a transfer of wealth and subsidies tells me all I need to know abouthow well you understand Economics 101.

The writer of the article. By the way, lawyers in the same position are called "ambulance chasers" (When I practiced law I was a business lawyer)
I think a couple of months from now would have been more appropriate to engage in this discussion.
On another somewhat related point, I have been reading the comments on Judith Curry. Is this all because of some interview I understand she had with Fox News? I am a little disappointed with her even appearing on that "news" source.
But I can tell you at one point when I was watching CNN and CBS etc covering Hurricane Irma when it was in the Caribbean, all of the predictions for the path of Irma at that time were up the east coast of Florida. I just happened to go on the Curry blog for other reasons (although I sometimes look at GWPF, I only regularly follow two blogs, one on each side).
At that time, when all the other predictions had the storm heading to Miami, Judith Curry's prediction that day showed the hurricane heading for the west coast of Florida.
It took another day before CNN was modifying its predictions. Perhaps there were others and this was just an example of news sources looking for the dramatic but it was both CNN and CBS.
So if one oil and gas company retains Judith Curry to predict hurricane paths I have no problem with that. People do have a right to earn a living while promoting their causes. I think her oil and gas interests are immaterial to the issues and have been fully disclosed. You cannot bar every person from this debate if they have had some present or past relationship with the fossil fuel industry. On that basis, everyone should disclose any advice (and compensation they receive) to any organization promoting the dangers of climate change.
PS One time I took a look at a YouTube video of the President of the Heartland Institute. That was all I needed to stay clear of that site.

@19 Tom13,
Please be more specific. Are we talking about my States plan which pays a farmer to sequester carbon based on verifiable increases of soil carbon? That's entirely different than fee revenue being returned to the citizens ... whether they are producing a goods or service or not.
We collect taxes all the time to pay contractors to build roads, schools etc..pay police and military etc... Those people providing for a public goods or service. So collecting a surtax to pay people sequestering carbon in the soil long term is well within our already established capitalist societies priciples and economic structures. It can be instituted very conservatively without negatively disrupting the economy at all. In fact by circulating more money that eventually will in the long run circulate through very depressed rural economies, it will be a big boost to economic developement. A win win for everyone.
But if we are just charging a surtax then paying revenue neutral dividends to every citizen regardless of any goods or services that citizen my produce...? That's just a wealth distribution program guaranteed to fail. The shuffling chair analogy applies.
So please be precise.

Bob Loblaw at 00:55 AM on 2 October 2017Climate and energy are becoming focal points in state political races
Tom13 seems to want to ignore the wealth transfer that occurs when the producers and consumers of fossil fuel energy avoid the externalized costs of that use and force that cost on to the taxpayers that pay for disaster relief, longer term health and environmental costs, etc. Taxpayers that include people that are not using those fossil fuels in large quantiities.
If I made and sold pencils, and I could find a way that the cost of the wood and graphite I consume was paid for by someone else (e.g. government), then I'd be the richest pencil maker around. Tom13 might think that having me pay for the wood is a "wealth transfer program", but other may differ.

NorrisM @ 45 and elsewhere
You are beating a drum of uncertainty on aboslute knowledge of what a specific temperature has been (e.g., choosing a baseline, etc.). You can have a degree of uncertainty on what the exact temperature is, but still have a very high degree of certainty on how it has changed.
To iilustrate through an analogy: let's say I have a neighbour, Sarah, who lives 6 houses up the street - about 100m north of me. I can describe the location of my house in latitude/longitude using NAD27, NAD83, or WGS84 coordinate systems, which will disagree on exactly how to label where I live. They may differ by 100m or more. I may not even know the lat/long very well at all - being kilometres off.
...but does this affect the accuracy with which I can direct someone from my house to Sarah's? No, not at all. I don't even need to know that NAD27, NAD83, and WGS exist.
The different global temperature series are akin to NAD27, NAD83, and WGS84. Regardless of what baseline is used, and how different temperature records are merged into a global measurement, they all show pretty much the same thing with a high degree of certainty.
The drum you are beating is a dead horse.

@18 Tom13,
Exactly Tom. Like shuffling the deck chairs on the Titanic. This is my main problem with Liberal mitigation plans. But if the dividends were paid to the people sequestering carbon long term, then it would be paying for a goods/service that benefits society. That's a market rather than a wealth redistribution plan. Sure in some ways all economies are wealth redistribution, but that would redistribute to a producer! That's a good thing.

Tom13 at 00:00 AM on 2 October 2017Climate and energy are becoming focal points in state political races
. The way fee and dividend works is a fee is charged to companies that produce greenhouse gas emissions. No longer would society be subsidizing the costs from carbon pollution.
The revenue from the fees would be returned to citizens so that it becomes a revenue-neutral tool. There is no net increase in cost or increase in income. What the fee and dividend method does, however, is reward people and companies for good choices.
In other words - its a surtax - with a subsidy for renewables and a wealth transfer program.
