ronald myers at 08:42 AM on 2 September 2015Tracking the 2C Limit - July 2015
Like Tom Curtis (Comment 11) indicates the use of a reconstructed temperature existing prior to the industrial revolution and the expansion using fossil fuels should be the goal. If it is believed that only data collected with temperature measurements are considered adequate, then the use of the HadCRUT4 data should be considered to extend the baseline back by thirty years. But as I believe Rob Honeycitt (Comment 29) and Tom Curtis (Comment 30) infer but do not state, one could use the large number of temperature estimates which characterize not only the pre industrial temperatures but also estimates of the normal variability and rate of change.
I have extracted the first thirty of the one hundred Realisation's in the HadCRUT4 Gridded data: ensemble members data set. I averaged the monthly ensemble members to arrive at a monthly value. Then I averaged the 30 years from 1880 to 1910 and the 30 years from 1850 to 1880. The earlier period was warmer by only 0.07 C. While I used the arethmetic mean verses Hadley use of the median value, the difference is not significant since the data are nearly normally distributed (based on a skewness and kurtosis of less than 0.1).
Next, I downloaded the data used by 2010 Frank et.al. for their January Nature paper. I adjusted the baseline of that data to both a 1880 to 1910 timespan and a 1850 to 1880 timespan. I then averaged the temperature anomalies from year 1000 to 1800. The average anomaly for the 1800 pre industrial years was only 0.03 C different from the 1850 to 1880 period and only 0.06 C different from the later period.

moreover at 06:14 AM on 2 September 2015Citi report: slowing global warming would save tens of trillions of dollars
Rob, I agree it was a missing moral hazard and you described the mechanism well. An excellent account of the mortgage crisis comes from economics prof Richard Wolff: "Housing Crisis, System Failure"
The massive decline of profitablility of the coal industry has already begun with the remaining players posting hundreds of millions of losses quarter after quarter.
Tuesday 8/4/15 #2 US coal company Arch Coal resorted to a a 10:1 reverse stock split that went into effect yesterday ( so their stock that had been worth about 17 cents/share went up (about) 10 fold in value and all of a sudden was worth about $1.60 per share. Otherwise they would have been kicked off the NYSE for being below $1 per share for too long.
Alpha Natural (ANR) was taken off the NYSE and filed for bankruptcy on Monday 8/3/15.
# 1 coal company Peabody at some point dipped to $1.10 per share - you get the picture.
Reuters tracks such figures, eg: Peabody stock figures

Rob Honeycutt at 03:16 AM on 2 September 2015Citi report: slowing global warming would save tens of trillions of dollars
bvangerven... I'm not perfectly sure, but I think it's the reverse. There was a missing moral hazard in the banking crisis because, in the end, the lender banks were able to transfer the risk of their loans to the capital markets. And when those investment banks took on those consolidated loan packages and converted them into securities, they had no idea of their intrinsic value, but that also didn't matter to them because in a crash the taxpayer ends up having to bail them out.
There was a lack of moral hazard permiating the entire home loan industry when the banks operate in a way that they have no risk. It didn't matter to them because they're so large and so important to the economy of the nation, the government can't allow them to fail.
The risk in the FF industry, as I understand it, has to do with the fact that the valuation of FF companies is buoyed by the idea that they can continue to explore and extract reserves. The reality is, they can't continue to extract those assets and those assets are going to have to stay in the ground. So there is "wasted capital" in terms of exploring for reserves that ultimately can't be extracted that, in turn, become "stranded assets."
See Carbon Trackers: Unburnable carbon 2013: Wasted capital and stranded assets report.

@scaddenp (#69): Agreed, up to a point. Remember that only a fraction of petroleum is suitable as feedstock for plastics, and that processes such as cracking take a lot of energy. Doing something other than burning the non-feedstock fraction will take considerable discipline, or incentives.

braintic @78.
The "one match every 3½ years not 20 years" concerns the one match in the room to raise the CO2 level.
A comparison without getting too confusing. I am saying the room is bigger than your estimate (your room 30% the size of mine) and my match estimate works out smaller (my carbon content estimate for a standard sized matchstick 0.055g(C) to your 0.093g(C)).
This still leaves the size of matchstick that Giaever is working to. If he estimates the air in the room and atmosphere correctly, his match would be very big indeed at 0.3g(C), even bigger than a large kitchen match (0.34g per item, so carbon content 0.17g(C) each).
As for your strike rate, that would increase with the smaller matches from 1.3 matches/person/minute to 2.3. But note that only represents the carbon from car exhaust pipes that remains in the atmosphere. If this mass striking of matches is carried out in the open air, much of the released carbon would be absorbed by oceans and biosphere. We would have to strike 5 matches/person/minute to achieve the same rate of carbon release that car exhaust pipes do.

bvangerven at 23:13 PM on 1 September 2015Citi report: slowing global warming would save tens of trillions of dollars
(From wikipedia:) “In economics, moral hazard occurs when one person takes more risks because someone else bears the burden of those risks. A moral hazard may occur where the actions of one party may change to the detriment of another after a financial transaction has taken place.”
The mortgage crisis of 2007 was caused by moral hazard.
The same mechanism is now at work in the fossil fuel industry: although the potential damage in a business as usual scenario is enormous, it is not the fossil fuel industry that will bear the consequences.
Therefore I am strongly in favor of eliminating the moral hazard, as follows: make it clear to the fossil fuel industry that they WILL have to pay the bill. Either in the shape of a carbon tax that will allow society to evolve to a low carbon society, or in the shape of damage compensation. As the report from Citibank shows, in the latter case the bill will be much higher. -
braintic at 19:30 PM on 1 September 2015Ivar Giaever - Nobel Winning Physicist and Climate Pseudoscientist
I'm not sure what you are saying in your last sentence.
I didn't say "one match every 20 years".
I said one match every minute FOR 20 years.
Further, when carbon burns to give carbon dioxide, it combines with oxygen from the air, so it picks up mass. The molecular weight of carbon is 12. The molecular weight of carbon dioxide is 44, with the extra mass coming from an external source. So you have to multiply your estimated mass of carbon dioxide by 44/12.
Re the ratio of atmosphere to room size - yes I was considering volume instead of quantity of air, so that calculation would be out somewhat.

One Planet Only Forever at 14:39 PM on 1 September 2015Citi report: slowing global warming would save tens of trillions of dollars
There are additional factors fueling the opposition to doing what the constantly improving understanding of things indicates needs to be done.
There are many consumers who perceive themselves to be prosperous because of the jobs they can have and the energy and personal benefit they can get cheap as long as they defend the developments that have been gotten away with by "the group of wealthy people who have clearly understood the unacceptability of their pursuits for at least the past 25 years".
As a resident of Alberta, Canada, I am very familiar with the push for perceptions of prosperity through the expansion of the rate of extraction and sale of fossil fuels. The oil and gas and coal were pushed out through the 1990s. As the conventional oil and gas was depleted it was realized that they had to move fast to benefit from the burning of the oil sands, moving it out quickly to be burned by others.
Popularity and profitability can clearly be misleading measures of the merit, value and acceptability of things (or people). The misguided belief in the virtue and value of those things clearly needs to be overcome. And the misguided belief that 'everyone being freer to do as they please will develop good results' is another significant factor that needs to be changed.
The opposition to that adaptation of humanity to deal with the challenge of the impacts from the unacceptable popular pursuits of profit will always be strong. There is likely to always be a significant minority of humanity looking for ways to get away with the least acceptable (cheapest), things they can. Simple rules easily monitored and enforced are likely to be the most effective ways of dealing with that challenge.
Globally, maybe there needs to be a rapid transition to a ban on the export of fossil fuels by any nation (or region in a nation). After all, in less than 50 years that will need to be the global reality combined with the reality that nations or regions with fossil fuels won't even be allowed to burn them up internally, especially regions in currently developed nations.

Tom Curtis at 12:13 PM on 1 September 2015Tracking the 2C Limit - July 2015
CBDunkerson @34, BEST gives an Alaskan trend increase of 1.58 C from 1860-2014, and 1.08 C from 1910-2014. The trend increase from 1960, however, is 1.88 C per century. The sharp increase may be because of a cooling trend from 1860-1960, or because earlier data was obtained only from southern coastal regions and the Yukon Valley, both of which show reduced trends relative to Northern Coastal regions. (Seen clearly in the GISS 250 km trend map.)
More importantly, I don't think targets work like that. Specifically, in tropical regions, because of low annual temperature ranges and a small gap to the maximum tolerable wet-bulb temperature, small increases in temperature will be more harmfull than much larger increases in the Arctic and Sub-Arctic. Against that, the absolute threshold for melting ice is a significant factor in the Arctic in general, and Alaska in particular. Temperature increases in the Arctic that raise summer sea and/or permafrost temperatures above freezing will be far more harmful in the general context than much larger increases above that level. So, depending on latitutude and local conditions, a significant increase may have relatively little effect but once a threshold is crossed the impacts can rapidly become quite large. To complicate things further there are no doubt other thresholds (relating, for example, to the life cycle of beatles) which will also have significant effects. The upshot is that impacts will not scale simply with temperature increase, and will vary significantly from region to region, and event within a small radius based on local topology for a given level of increase.

Hey, Obama's trip to Alaska got me thinking... given that 'the Arctic is warming twice as fast as the globe as a whole'... would that imply that places like Alaska and Siberia are already AT the '2 C limit'?
Obviously, the 2 C limit is meant as a global average, but is there some applicability as each regional area passes that thresh-hold? That is, are the level of changes being seen in Alaska currently similar to what the whole world will see at 2 C?

New paper shows that renewables can supply 100% of all energy (not just electricity)
tder2012 - Personally, I do not expect the path to low-carbon energy to be simple, and many of the proposals for accomplishing that are indeed more thought experiment than detailed proposals.
However, if we were to implement costs on fossil fuels commensurate with their impacts, such as a carbon tax, accompanied by government policies supporting rather than undercutting renewables, I expect the move to low-carbon energy in all sectors of the worlds economies will occur simply due to the profit motive.
The second reference you put forth, Vidal et al 2013, has as its abstract:
Renewable energy requires infrastructures built with metals whose extraction requires more and more energy. More mining is unavoidable, but increased recycling, substitution and careful design of new high-tech devices will help meet the growing demand.
Given the doubtful tone of your post, I would have to note that the referred article is actually quite optimistic.

Rob Honeycutt at 00:58 AM on 1 September 2015Corrected sunspot history suggests climate change not due to natural solar trends
qikplay... Do you understand the relative forcing of those solar cycles on the climate system compared to other forcings? The difference in the last two solar cycles relative to the previous few is a teenie-tiny signal lost in the background noise. You're talking a small fraction of a watt/m2 relative to the 1361W/m2 of incoming solar radiation. We are lucky to orbit a very stable star.
You should consider the 2.3W/m2 of forcing from increased human activities as the culprit for the the changes we see in our climate system.

One Planet Only Forever at 00:15 AM on 1 September 2015Here’s what happens when you try to replicate climate contrarian papers
mancan18,
My observations of recent history, following the attempts of many people to develop improved understanding and raise awareness about the unacceptability of developed profitable and popular economic activity, indicate that a major barrier to 'the development of legitimate scientific development of the best understanding of what is going on, the general acceptance of that increased understanding, and the application of the understanding to develop lasting improvements of living conditions for all of humanity on this amazing planet' is a focus on "Scientific development that will lead to profitable and popular pursuits, including the science of marketing to promote those pursuits".
The pursuers of profit and popularity clearly have little reason to investigate and educate the population about the potential unacceptability of their pursuits. They may investigate them, but they choose what to promote about their pursuits. And since it is always cheaper if you can get away with a less acceptable action the chase after popularity and profitability naturally leads to a deliberate lack of awareness regarding the unacceptability of things, either because of a lack of investigation (the ones making the money are not interested in understanding the unacceptability of the ir pursuits), or a lack of sharing what has been learned (If the ones making the money become aware of an unacceptablilty related to their pursuits they will not want others to know about that unacceptability).
And people who pursue personal perceptions of prosperity can have little interest in hearing about the unacceptability of the cheaper ways they have been able to get away with believing they are prosperous. Cheaper ways almost always are more damaging and are ultimately unsustainable limited opportunities that people have to fight to be the biggest beneficiaries of (to the detriment of others).
The pursuit of profit, pleasure and perceptions of prosperity today can be seen to be the equivalent of religion in the 17th Century. That focus is a barrier to the development and acceptance of increased understanding of what is going on. Popularity and profitability today have clearly been a barrier to the development of human activity toward a lasting better future for all of humanity, just as the unjustified religious beliefs were in the past (and still are in many regions, including in developed nations, on many issues today).

MA Rodger at 21:23 PM on 31 August 2015It's the sun
qikplay @1152.
You may feel trawling SkS to identify posts to criticise is helpful but do pause a while. The BBC 'myth' addressed in the post here dates to 2004 and was written by David Whitehouse, a man suffering deep denial on AGW. Indeed, he has since been recruited by the GWPF (Gentlemen Who Prefer Fantasy). Whitehouse reports the work of Solanki which have been lost and forgotten by all but AGW deniers. And that is because the evidence, the data and graphs, demonstrates Solanki is plain wrong. You appear to reject the use of "competing graphs and data" as a way examining the unsupported fantasy of the likes of Solanki. How then would you suggest we examine his wild claims?

braintic @76.
The room and the match anaolgy, "Iian Samson's problem" (at 27 mins in the video) is new to me. I found no internet comment so I did a quick back-of-the-envelop calculation.
The ratio of atmosphere to the room is a little bigger than you calculate. Taking the troposphere as 80% of the full atmosphere yields a gas content of 3 x 1016 rooms. The analogy's use of CO2 levels increased by cars alone is a bit curious, but this is usually considered as 10% of the total CO2 emissions, thus perhaps causing +0.22ppm/year.
That leaves the match. Perhaps Giaever uses giant matches, but the usual sort, the sort used by marchstick model makers weigh 0.11g. With 50% carbon content that puts the answer at one match every 3½ years not 20 years, a significant difference.

Yes, an obvious typo, but humorous none-the-less. That along with the statement that he has an article published on NoTricksZone dated August 28, 2016.
He seems to be somewhat temporally challenged, in a way that a simple proof reading could cure.
-
Tom Dayton at 10:37 AM on 31 August 2015There's no empirical evidence
Tom Curtis, the odd phrasing of Dilley's bio leaves unclear whether he actually got a B.S. or an M.S. Normally people list "B.S. Meteorology," or "B.S. major in Meteorology," and "M.S. Meteorology, emphasis on climatology." Instead Dilley wrote "studies for B.S." and "studies for M.S." It's possible to audit graduate classes, and in some schools to even take them for credit, without being in that school's Masters program. So maybe he took classes but never got his B.S., or got his B.S. but never got his M.S. His misunderstanding of what causes seasons is evidence that he was incapable of getting either degree.
-
Tom Curtis at 10:01 AM on 31 August 2015There's no empirical evidence
Rob Honeycutt @288, David Dilley claims on his website to have an MA in meteorology, and to have worked with the US Air Force and then NOAA as a meteorologist. He also claims only two, self published papers on climate, so no peer reviewed publications at all. His masters thesis appears to not have been published.
What I find interesting is his claim that:
"Global temperatures have cooled during the past 12 months. During 2008 and 2009 the first stage of global cooling will cool the world’s temperatures to those observed during the years from the 1940s through the 1970s. By the year 2023 global climate will become similar to the colder temperatures experienced during the 1800s."
The research justifying the claim is supposedly contained in an e-book for which his website no longer provides links. The prediction was made no later than August of 2008, so it predicts continued cooling in 2009 to "temperatures ... observed during the years from the 1940s through the 1970s". For the record, 2009 was 0.1 C warmer than 2008. It was also 0.6 C warmer than the 1940-1979 average, and 0.46 C warmer then the 95th percentile of 1940-1979 global temperatures (GISS LOTI). No year since 2008 (when the prediction was made) has been as cool as, let alone cooler than 2008.
For his 2023 prediction to be valid, global temperatures must fall by more than 0.1 C per year for eight years running - a rapidity of temperature change not witnessed at any time in the modern record. No doubt that prediction will be a bust as well.
As a predictions of global temperatures, these are among the most spectacular fails ever seen. It is also inconsistent with his claim to be a reliable predictor of short term climate and ENSO states in general. Consequently it is no surprise to find no archived copies of his predictions at his website. We 'know' he is a successful predictor only because in 2015 he tells us what his predictions for the years up to 2015 were.

Tom Dayton at 09:08 AM on 31 August 2015There's no empirical evidence
ringingrocks: The credibility of David Diller is low, given that he claims to be able to accurately predict ENSO events (El Nino & La Nina) and hurricanes four years in advance, yet does not show his past predictions versus the realities, despite him having been in his business for 25 years. He also claims to accurately predict earthquakes. And claims that in 2025 global temperatures will hit a catastrophically major low. And then there is this astonishingly wrong claim that a grade schooler could correct, but which apparently is a key basis for his predictions: "The gravitational cycles of the moon and sun cause the seasonal tilts of the earth's axis and the 4 seasons."

Overall, best I can make out, Mr. Dilley does not have the credentials that he claims. A quick search on google scholar doesn't turn up any published research by a DA Dilley on any climate related issue. You're probably better served by sticking with actual researchers in the field of climate science.

Tom Curtis at 08:13 AM on 31 August 2015It's cosmic rays
Quikplay, if you read carefully, you will see that the myth is that "It is cosmic rays" that is causing the current warming, or more correctly, it is a paucity of cosmic rays that cause the warming. There is no claim that it is a myth that cosmic rays exist. Nor is there any claim that it is a myth that cloud extent effects global temperatures. Nor is there any claim that it is a myth that cosmic rays seed clouds.
As to your anecdotes, yes it snowed in July on Hawaii at 13,000 feet. At that altitude, with the normal lapse rates temperatures are 26 C less than surface temperatures due to altitude. As it happens, the temperature in Hawaii at sea level on the day of the snow (July 17th) was a 90 F (32 C) maximum, and 79 F (26 C) minimum, 2 and 5 F above average respectively. Noting the average July minimum temperature, it is evident that snow in July on the mountain peaks is a rarity primarilly due to lack of thunderstorms early in the day to lift the humidity that high.
As to Calgary, on average it snows in August in Calgary every ten years or so. And you want to count that as evidence of a "mini-ice age"? As somebody just said, "lol feeling stupid [much]?"
Meanwhile you are ignoring the massive, and extended heat wave in the state of Washington, the heat wave in the heat wave in Pakistan that killed 2000 people, and the heat wave in India which caused the deaths of 2,500 people, as well as the heat waves in Europe, and China. In fact, you ignore all the evidence that show 2015 to be the hottest year todate by a large margin, which along with a significant El Nino is causing predictions 2015 will be the warmest year on record:
So please, no more demonstrations of your complete lack of reading comprehension (ie, your persistent and obtuse misidentification of the myth); and no more cherry picking.

BBHY at 07:23 AM on 31 August 2015How to make sense of 'alarming' sea level forecasts
I feel like the question of whether the new study from Hansen's group is accurate is not the right question. IMHO the right questions are:
1) Is is possible that the study is correct?
2) Even if it is not, willl sea level rise be great enough to cause us serious trouble?
3) How confident are we with the answer to #2?
4) After the sea rises, is there anything we can do to reverse it?
The answers are 1) Yes, 2) Yes, 3) Very 4) No.
Hence the urgent need to cut CO2 emissions as soon and as much as possible.

Qikplay, your lists of anecdotal blurbs is not even funny. Have you even tried to figure what the global temperatures have been so far this year? And last year, the warmest on record? With the immense majority of glaciers receding and loosing mass all over the world? It seems that your participation here is another thing not deserving of any attention. It seems the snow in Calgary has not prevented the region from enacting a fire ban. And what was the wildfire season like this year in Canada again? Do you honestly think that, on a website where scientific evidence is discussed, you rantings would have a chance to sway anyone? An ice age eh? Illustrated by a Arctic sea ice once again below average by more than 2 standard deviations? Makes perfect sense right?
Per environement Canada, the long term trend 1948-2013 for winter temperatures is +3.2 degrees C. The annual average has increased by 1.6 degrees over the past 67 years. Some ice age that is. Personally I think that moderators summarily delete such obvious nonsense as your last post.

no clear evidence for GCRs actually being a significant factor
Yes, but that's a far cry from 'doesn't exist' dont you think?
Moderator Response:[RH] Your concern has been addressed already, saying that GCRs are responsible for global warming is the myth. You're going to have to find a way to accept that and move on. Repeating the same error is considered sloganeering is not allowed here.

It's even worse than Rob suggests. The hypothesis is that GCRs seed clouds and that the resulting cloud cover modulation is a forcing, i.e. responsible for the current warming. Not only there is still no clear evidence for GCRs actually being a significant factor in nebulosity, but the recent GCR count shows an increase, which would mean more cloud and a cooling effect. This whole idea that GCRs influence the climate is a joke, coming from people so desperate to distract attention that they will grasp at the most feeble of straws. It does not deserve any attention whatsoever.

OK, sorry for the rude all caps shit..
BUT (whoops) You don't say something is a 'myth' then admit that it's not a myth in the first paragraph of your commentary! what are you thinking.. it's not a myth, rather its extent a bone of contension between you and other scientists, pundits etc..
you don't say something doesn't exist, oh but actually it exists just not that much.. big difference there and talk about being misleading perhaps you should take this off your 'myths' section lol feeling stupid?
and the reason its not responsible for the recent warming is that there is recent cooling like snow in calgary in august, snow in hawaii in july, polar vortex in 2014..how long do you think you can keep up this sham that the mini-ice age isn't really happening? (snip)
Moderator Response:[RH] Please be more careful. I'm going to drop out of commenting here and just moderate. You really need to go carefully read through the commenting policy before continuing to post.

qikplay... The myth would be that GCR are responsible for warming of the past 50 years. That GCR are "not very effective" at seeding clouds suggests that they are, in fact, not responsible for recent warming.

Also much larger turbines are being built and at 140 meters their capacity factors usually exceeds 60%. Furthermore the wind at that height is available in many more locations.

I'm a bit late to these comments too. The idea that renewable energy needs rare earths is outdated. As somebody already pointed out it is not used in normal solar panels. What has not been mentioned is that modern gearless wind turbine magnets only use .7% or less dysprosium and will soon use none. The neodymium may be considered rare but there is an endless supply throughout the world making the term "rare" not appropriate. For reference read the last three paragraphs of this BBC article: http://www.bbc.com/news/magazine-26687605

I like the way you write this, "The body of scientific research has determined that GCRs are actually not very effective at seeding clouds."
'not very effective' so it's not a 'myth'
don't say it's a myth and then admit that it's not a myth in the first paragraph of your editorial! That's called a fallacy of logic, something you people seem to excel at.Moderator Response:[Rob P] - All caps edited out - please note the comments policy that you agreed to adhere to when commenting here.
As for logic: note that the rebuttal points out that GCR's have increased in recent decades -which should have seeded more clouds and induced a cooling effect. Instead the Earth has warmed dramatically. The bottom graphic is very unintuitive though.

scaddenp et al.
Arriving at this discussion somewhat belatedly, it seems appropriate to point out at this juncture that Ricardo said recently they have designed a low cost, rare earth free EV motor:
