Gingerbaker at 10:53 AM on 28 August 2017Analysis: Why US carbon emissions have fallen 14% since 2005
Meanwhile, back at the ranch, [CO2] keeps rising. And here is a thought:
Reductions in electricity and fuel use, mainly from efficiency gains, resulted in how much additional pressure to build new renewable energy infratsructure? Answer: zero. Actually, less than zero.
I am not saying efficiency is not a good thing. But the only thing that truly matters is how quickly we can build and deploy all the RE we need to stop burning carbon.
It seems a prosaic point, but, you can't hit the switch to turn off a coal or natural gas power plant until you can hit a switch to turn on the RE plant to replace it. And funding that RE plant is a function of government, not the individual. Replacing incandescent light bulbs with LED's is not the answer, it is rearranging the deck chairs.

ubrew12 at 03:13 AM on 28 August 20172017 SkS Weekly Climate Change & Global Warming News Roundup #34
Reading the Aug 18th 'Moyers and Company' interview with Katherine Hayhoe about the National Climate Assessment report, she's talking about the dangers to parts of America posed by climate change and made this remark: "In Texas, we’re at risk of hurricanes, which are getting stronger as we’ve got the warmer ocean water". She can say that last week, but such is the politics of the situation that if she said it this week she'd be accused of grandstanding.

"... requiring the wealthy of the nations who got richest from the previous decades of massive damaging burning of fossil fuels ... to 'transfer wealth and provide support' to genuinely sustainably improve the lives of those who undeservingly lose in (experience a net-negative result) due to the fatally flawed games of popularity and profitability."
Many of the people 'Losing' are not 'in the games' and would perfer to enjoy life 'outside of, and not negatively affected by, the fatally flawed competitions for temporarily developed perceptions of Winning more than Others any way that can be gotten away with'.

A follow-up to my comment@24,
Misdirection/misleading messages regarding many aspects of the increased awareness and better understanding get popular support by creating 'unjustified perceptions of anxiety leading to misdirected fear and resulting in misdirected anger' related to the requirement for human activity to be corrected to undo damaging development along the fossil fuels burning path.
Undoing decades of prolonging and expanding economic development based on fossil fuel burning is a major correction of perceptions of prosperity. In Alberta it can be seen that the push to expand extraction facilities for the Oil Sands was done to increase the number of people incorrectly perceiving their opportunity for prosperity to be related to excusing the global burning of fossil fuels and disliking and attacking anyone who says otherwise.

ubrew12@23,
A misdirection to create 'unjustified perceptions of anxiety leading to misdirected fear and resulting in misdirected anger' that is pertinent to the corrective actions that climate science has exposed as being required for the advancement of humanity to a truly lasting growth of economic activity making things better for everyone is: Claims that the inequity of distribution of the truly massive wealth within the USA is to be blamed on things like NAFTA.
The people easily tempted to be angry about 'Others' benefiting from agreements like NAFTA are also easily tempted to be angry about the Paris Agreement requirement for the inequity of global wealth and harm due to climate change impacts to be corrected by requiring the wealthy of the nations who got richest from the previous decades of massive damaging burning of fossil fuels (decades that saw the damaging activity be prolonged and even increased in spite of it being well understood that development in that direction was damaging and unsustainable though undeniably cheaper for those benefiting for as long as the understandably damaging ultimately unsustainable activity can be gotten away with - any growth in perceived prosperity/wealth could not be expected to be maintained), to 'transfer wealth and provide support' to genuinely sustainably improve the lives of those who undeservingly lose in the fatally flawed games of popularity and profitability.

"- climate change costs will hit Trump Country hardest." It doesn't matter. The 1%-funded alt-media (Breitbart, Faux News) peddles the alternative fact that whatever happens to 'Trump Country', its someone else's fault. This is its sole purpose. So the more 'Trump Country' is squeezed, by anything including climate change, the more imperative it will be for them to vote for people like Trump. What happened to the Germans in the 1920s was the fault of the Jews (not their centuries-old rivalry with the Franks which ended badly in WWI). This is a time-honored tradition for the kind of people for whom certainty 'trumps' accuracy. Whatever happens to 'Trump Country', their media will simply wheel out the 'usual suspects' to direct their anger. Which tiresomely was revealed the other day in Charlottesville VA with the chanted slogan 'Jews will not replace us'.

nigelj,
Regarding what humanity needs to focus on ... The 2015 Sustainable Development Goals are probably the most robustly developed (having the most extensive and rigorous effort put into its development) set of actions that humanity must "cocurrently pursue".
Those goals were developed through massive international cooperation in increasing awareness and understanding through the years since the 1972 Stockholm Conference.
For the likes of Lomborg to claim that "They know Better" without actually providing 'substantive Good Reasons based on new information' as the basis for changing the SDGs is the epitome of damaging dangerous hubris. It is simiar to the ridiculous 'US Supposed-Winners-of-Leadership-in-the-Moment' claim that their Red Team-Blue Team climate change assessment would be more relevant than the IPCC reports and recommendations.

This is perceptive about Lomberg and his "copenhagen consensus"
We need to stop our obsession with global warming, and start dealing with the many more pressing issues in the world, where we can do most good first and quickest," Lomborg concluded.
While Lomborg's views are dismissed by the overwhelming majority of those researching climate change, his attendance in Buenos Aires ensured that his views where not only projected into the 'echo chamber' by conservative news sites such as CNSNews.com, but picked up by the BBC as well.[15]
Others don't think the outcome of the Copenhagen Consensus should be taken all that seriously. Not only were the invited presenters all economists, critics of the process point to the constrained choices they were presented with in ranking priorities that the global community should address.
"Climate strategies are compared with measures to address problems that everyone agrees are crucial. But climate strategies should also be compared with other goals that society spends (or wastes) money on. One relevant example is to ask what can be delayed with the least harm: climate measures or exploration of Saturn’s rings? Or what about ranking climate measures in relation to spending tens of millions of dollars a year developing new kinds of nuclear weapons, as the Bush administration seems prepared to do?," wrote Pål Prestrud and Hans Seip from the Center for International Climate and Environmental Research (CICERO).[16]

You could be right. Some people are indeed scientifically literate enough to know whats really going on, but deliberatly misrepresent things for ulterior motives. But I have known very bright well educated people who are just weak in science.
Either way the result is the same, and Lombergs mistakes are as you say too numerous to excuse. The Danish Ministry of Science also found his book scientifically dishonest, in a formal hearing, although he was cleared of personal dishonesty. But if thats not still a red flag what is?
Lomberg has demonstrated over and over that he cannot be relied upon to be accurate and objective on matters of climate change, and he also has a strong sceptical position, therefore there will always be a suspicion this colours his economic analysis of the Paris issue.

nigelj@16,
In order for Bjorn Lomborg to have made his 2008 claim about sea levels he was almost certain to have been aware of the data history, including data prior to 2006. He would have been looking for the longest duration he could claim for the 'no sea level rise for the past ??? years'.
Therefore, he most likely was well aware that the history includes other periods that would appear to have been the 'end of sea level rise'.
Therefore, he most likely deliberately made-up his misleading claim to achieve an understandably unhelpful/unacceptable objective.
Therefore, he has little reliability/credibility as a source of valid information or Good Reasoning. He has very little reliability as an information source.
All sources can be shown to have 'made some mistakes in the rush to be the first to present new information'. The more reliable sources make fewer and less significant 'mistakes'. But the 2008 claim made up by Bjorn was not a researcher's 'mistake' due to a rush to claim something first. It was wrong in a way that Bjorn Lomborg would have easily been aware of (and part of the blame has to go to all the media that published his claim 'uncorrected for the easy to establish fallacy that it was').
People wanting to believe the claims made by the likes of Lomborg have to be unaware of the lack of reliability of such sources. Their continued 'faith' and 'belief' in things that are contrary to available evidence and the best explanations of what can be observed/discovered is due to a motivation to 'want to continue to believe the unbelievable'.
History is filled with cases of people preferring to believe something contrary to the actual developed better awareness and understanding. And they have often argued for 'what they believe' (maintained understandably incorrect beliefs) for hundreds of years after the virtually conclusive unacceptability of what they prefer to believe has been established.
There truly are some things outside of increased awareness and better understanding, such as spiritual beliefs. But a spiritual believer is also capable of changing their mind based on increased awareness and better understanding. It is interesting to note that many people claiming a spiritual belief as the reason they do not accept an understanding of science also claim that all beliefs should be considered to be valid (an implied equivalence of validity for any belief). But they also insist that their preferred belief is the 'correct one' which is a clear contradiction of their claim that all beliefs are equally valid (and all spritual beliefs/atheism are all to be considered to be equally valid until actual independently verifiable substantial proof shows otherwise). The 'Believers' appear to detest Good Reason and True Expertise because it contradicts their preferred way of thinking - believing rather than understanding - in a way they cannot legitimately rationally argue against).
The best understanding of what is going on eventually wins, but often not before massive damage is done by Undeserving Winners of competitions for popularity and profitability getting away with the support of 'Beliefs that are Ridiculous' as Excuses for actions that are understandably unacceptable.

Eclectic at 01:47 AM on 27 August 2017Most of the last 10,000 years were warmer
Redrum @97 ,
best if you define the meaning of "such climate optimum".
"Optimum" is a term which is in much danger of being very subjective and bordering on useless for discussion. To look at it more closely would require a careful examination of plant/animal evolution, and of course the present rapid rate of global warming (in relation to biological adaptation of species).
If I were pressed to give a facile comment, I would say that global climate conditions at year 1950 AD might represent somewhere close to (biological) optimum. You will have noted from the OP's article and various commentaries on it (including graphs), that 1950 climate is rather similar to the broad span of the mid-Holocene.
And that the large and continuing rise in temperature since 1950 does push the global climate well above the earlier Holocene warm plateau — and much more of that hotting-up is yet to come [to our detriment]. So unfortunately, the "Optimum" is receding well into the past, and with little likelihood of being regained in the next few thousand years.

What just amazes me and leaves me bewildered is this. Bjorn Lomberg has a degree in political science, with some sort of specialty in statistics. Now I respect his qualifications, but how can someone with a degree in statistics of all things point to a cherry picked period of a couple of years of decline in sea level? He of all people as a statistician should know such short periods mean nothing, are not represenatative, and this is doubly true because the graph posted above on sea level clearly shows similar "blips" all through the 20th century of decline, but within an overall century long increasing trend.
So it proves the old saying you can have a PHd degree in whatever subject, and still be incredibly stupid at times. Perhaps I'm being rather rude and blunt. So terribly sorry about that.

Swayseeker @2; https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5067572/ about passive cooling. All electromagnetic radiation,light included, gets converted to lower wave-length radiation and re-emited (as heat-radiation). Atmosphere is buffering a lot of that heat in the form of latent heat in water vapor, chemical (potential) energy (Ozon, in the upper layers) and in the surface of the Earth. At night a lot of the captured heat goes out again into (cold) space as infra-red, partly reflected back by clouds. { so far, where does that energy go eventually }
Just a bit of the incoming radiation (7 out of the 174 units of energy) is reflected directly back into space during the day. One does increase direct reflection amount, especially in heat islands as city by painting with heat reflecting paint, which tend to be white in (visible) range. Painting asphalt roads grey would keep the temperature of the surface low, reduces the costs of maintenance, wear on car tyres in the long run. If that is worrth a $40,000 a mile, I don't know.

One Planet Only Forever at 11:39 AM on 26 August 2017New study finds that climate change costs will hit Trump country hardest
NorrisM,
To clarify my points regarding the unhelpfulness of the likes of Bjorn Lomborg and Lord Monckton regarding the appropriate awareness and understanding of the changes of human activity that climate science has identified as being required to improve the future for all of humanity, it is important to understand that 'anything that does not improve the future for all of humanity is unhelpful'.
Another way of saying that is 'only activities that have a net-zero or net-positive impact on Others are acceptable'. That is the fundamantal ethic behind sustainable rule of law. Any law and application of law that does not meet that measure ultimately deserves to be rewritten or revoked (like revised definitions of what Environmental Protection must include). And it is a rational consideration from the perspective the person affected, not the person making the impact, that determines if there is a net-negative impact.
The burning of fossil fuels, therefore, only becomes acceptable if there is no net-negative impact on any Others, with future generations being considered to be Others.
The likes of Lomborg and Monckton (and Trump) appeal to the selfish interests among the current generation. They try to claim that it is OK for some among the current generation to benefit from an activity that is understandably creating net-negative impacts for Others. They base their claims on showing that, from their perspective, the opportunity that has to be given up by current day people is less than the harm, costs and challenges that are being created for Others. And they attempt to justify more future harm by applying what is called a net-present-value assessment (or discounting of future costs) that reduces the value of future costs the further into the future they are. And they do not acknoweldge the 'Others' aspect. They instead claim that the harm done is acceptable as long as it is less than the opportunity to benefit that they evaluate would have to be given up by current day people since the result is a net-neutral or net-positive from their perspoective. That type of evaluation can easily be seen to be ridiculous, yet it continues to be used and be popular.
It is undeniable that much of the developed economic activity of the supposedly (perceived and claimed to be) most advanced nations and corporations was developed in the wrong direction (unsustainable activity). Those who continued with that incorrect direction of development since 1990 (and even earlier, potentially as early as 1972 when the Stockholm Conference identified the required changes of direction), have only themselves to blame for the current developed fact that making the required changes as rapidly as they need to be made is 'to their significant disadvantage'.

NorrisM,
I would suggest that SkS is about increased awareness and better understanding of all matters related to climate science, which would include understanding the basis of claims made regarding actions required because of the constant improvement of understanding of climate science.
From my perspective climate science has raised awareness and better understanding of the fatally flawed belief that 'everyone freer to believe what they want and do as they please will develop Good results'. The evidence is overwhelming that misleading marketing and the flawed perceptions of prosperity, popularity and profitability it an create and prop-up are a major hurdle to be overcome by climate scientists as they try to ensure the success of their efforts to improve awareness and understanding.

One Planet Only Forever at 09:32 AM on 26 August 2017New study finds that climate change costs will hit Trump country hardest
I have read Lomborg's "Cool It".
Basically the assessment is seriously flawed for many reaosns, not least of which is the fatally flawed belief that it is OK for a group of people to pursue personal benefit in ways that are understood to create harm, costs, and challenges for Other People.
The arguments against acting to reduce climate change impacts are basically comparisons of:
- the current day lost opportunities to benefit from the understood to be damaging activities athta are also understood to not be able to be continued to be a benefit in the future (because burning up non-renewable buried ancient hydrocarbon is a dead-end activity with escallating costs to continue).
- with the perceived costs imposed on Other People in the future.
The bigest falacy is the belief that perceptions of wealth and value today will magically continue and increase in value in the future. That belief only works if the created value is sustainable activity with increased value being improved sustainable activity.
The like sof Lonborg can only argue that their last opportunity costs are greater than the costs they create for others. The simple rebuttal is that costs to others must be minimized to the point of being eliminated if humanity is to have a chance of advancing to a better future.

"His (Blombergs)2008 book only focuses on Kyoto but his website suggests that the Paris Agreement would achieve very little in the way of temperature reductions but at great cost to society."
Is that right? Do you always take someones book at face value? Have you even bothered to read the rather compelling criticisms of all Blombergs many books and ideas including the above, merely a google click away? We are talking a whole stream of basic errors in his work, missquting other scientists etc, etc. The guy is not a scientist or environmetal expert he is a statistician.
Blombergs study on the Paris agreement takes the most pessimistic possible evaluation of impacts and doesn't consider the costs of doing nothing. Its a worthless piece of paper.
You obviously dont trust the IPCC, a huge organisation, yet want to place your faith in a jacked up debate between a small handul of cherry picked experts battling things out according to the agenda of the climate denialist organisers. I mean I'm just laughing and laughing. I suggest you google the term Kangaroo court. I place precisely zero value in such a mechanism regardless of what they come up with.

"In Los Angeles they are using cool grey paint for pavements and it will cost $ 40 000 per mile. But will it help? Will reflection cause radiation to go through windows.'
Well obviously some will go through windows, but you need to have some faith in experts, and they clearly believe more is reflected to space than goes through windows, so theres a net benefit to lighter coloured pavements. You have really just asked a rhetorical question, and not provided any data that theres a problem. However I would sure like to see an evaluation if anyone has one.
"One of the big problems can be windows with sunlight entering... so virtually all enters via a window."
Office towers use low emissivity glasses and mirror glass etc to keep solar radiation out as much as possible. So the pavement issue is perhaps not a problem in that context.
Houses use ordinary glass that lets most solar energy enter. Lighter coloured streets would reflect some sunlight into houses, but given street width, it just seems to me most would get relected away from buildings.
In your typical more northerly temperate America city you actually want heat gain through windows in winter normally, and shading in summer. It's more of an issue of how you achieve this, and one of the best ways is to use ordinary glass which lets in plenty of sunlight, but have an extrnal adjustable awning, eaves or louvred shutter so you can keep heat away from the windows in summer

For a start Bjorn Lomborg's arguments (as described by you) are not "more focussed". In fact they are decidedly lacking focus. What is the point of researching non-carbon energy technologies if you do not implement them? By pushing the implementation of non-carbon energy we can help push that research and give it focus and urgency.
It seems rather laissez-faire to just rely on the hope the research is successful without following up on it to make sure it happens.

NorrisM at 03:52 AM on 26 August 2017New study finds that climate change costs will hit Trump country hardest
My understanding was that this website was limited to the causes of climate change and not to the costs and ways of dealing with those costs. Largely owing to what I believe will be a "Red Team Blue Team" analysis organized by the EPA (I assume this has not changed while I was on vacation), I have decided that I will not expend any further time on issues of how much temperature change we are headed for thanks to MGW until I have heard the results of this analysis. As argued by Scott Adams (on a Sam Harris podcast) this publicized Red Team Blue Team approach is the chance for the proponents of MGW to get the US public onside. I have to admit this could be somewhat of a "gong show" but if it is organized by someone like Steve Koonin, it does not have to be.
During my summer vacation, largely owing to the recommendation of Freeman Dyson (not personally, from a You Tube interview), I have now read Bjorn Lomborg's book "Cool It". Lomborg completely accepts that the present climate change is man-made but argues that massive reductions in the use of fossil fuels at this time does not make sense compared to having the nations of the world each dedicate, per year, .05% of their annual GDP to R&D focussed on non-carbon energy technologies. His 2008 book only focuses on Kyoto but his website suggests that the Paris Agreement would achieve very little in the way of temperature reductions but at great cost to society.
Can anyone explain why Bjorn Lomborg's arguments as to a more "focussed" approach to adaptation does not make sense?

Every article about the cost impacts of climate change should include the italics added below.
"New study finds that climate change costs will hit future generations and the less fortunate in Trump country hardest"
There needs to be a constant reminder that a significant part of the resistance to accepting the required changes of human activity that have been exposed by climate science comes from people who do not care that their actions negatively impact others, especially not being concerned when those others have little or no chance of "Meaningfully, quickly getting back at them for what they did". The people benefiting are not the ones suffering the consequences. Regions are not people. And future generations are not just an extension of the current generation in the business sense of evaluating near term vs. distant benefits.
The popularity of the unethical assessment that 'the opportunity for benefit that has to be given up by a portion of current day humans to stop creating harm, challenges and costs for others, particularly future generations, is too high' needs to be ended. Claiming it 'costs too much to behave in a way that does not cause harm to others, is a very Poor but Popular Excuse. And it has to be repeatedly exposed that Poor Excuses can and do win popularity and profitability contests to the detriment of the future of humanity.

Swayseeker at 23:26 PM on 25 August 2017New study finds that climate change costs will hit Trump country hardest
One cost that is already emerging is the cost of cooling cities. In Los Angeles they are using cool grey paint for pavements and it will cost $ 40 000 per mile. But will it help? Will reflection cause radiation to go through windows. They are planting trees, but trees reflect radiation - see below:
My understanding of this paint is that it reflects infrared. With an urban heat island effect, the sunlight (includes infrared and ultraviolet) enters the city and gets reflected around onto walls and so on. They absorb the sunlight to some extent and heat up. The sunlight coming in has mainly short wavelength. After buildings heat up they emit radiation of a longer wavelength. Some of this longer wavelength radiation will probably be reflected by the paint and some will go out to space. The infrared of sunlight is high frequency (short wavelenth ) infrared. The heated buildings emit longer wavelength infrared radiation, mainly. With white cool roofs some sunlight is reflected onto other buildings causing heat problems. One of the big problems can be windows with sunlight entering. Window glass transmits radiation up to about 2.5 microns (the energy goes through the glass if its wavelength is less than about 2.5 microns) and about 97% of solar energy has wavelength less than 2.5 microns, so virtually all enters via a window.
Now how much of this energy escapes? Well if the walls heats up to 50 deg C, then radiation from them that is above 2.5 microns will not escape. The answer is that far less than 1% of this radiation can escape through the glass because more than 99% of the energy radiated by the 50 deg C walls is of wavelength greater than 2.5 microns (using a blackbody approximation). If a particular cool paint does reflect infrared, where is the infrared radiation going to go? Remember angle of incidence= angle of reflection. One may note that green vegetation reflects solar energy of wavelength between 0.75 to 2.4 microns significantly. Most of this could be reflected through your window into your house (glass lets in radiation of wavelength less than about 2.5 microns). This radiation would heat up objects and the radiation from the hot objects would not be able to get out through the window again (wavelength too long). About 42% of solar energy is energy of wavelength 0.75 to 2.4 microns. -

Wol at 13:59 PM on 25 August 2017Harvard scientists took Exxon’s challenge; found it using the tobacco playbook
I hve a copy of the summarised report by the Director of a branch of Exxon's Research and Engineering science lab, in response to Exxon's request for research into the effect of increasing CO2.
It's dated Sept 2nd, 1982
In part:
"... The consensu is that a doubling of atmospheric CO2 from its pre-industrial revolution value would result inan average global temerature rise of 3.0° - +/- 1.5° C"
and:
"In summary, the results of tour research are in accord with the scientific consensus on the effect of increased atmospheric CO2 on climate......"
There can be no question that the top management of Exxon were unaware of the effect of CO2 back in at least the early eighties.

Michael Sweet @2, yes I agree absolutely, its fraud to hide problems like this from the public. But the point I was making is some people I know don't even believe in those types of laws.
The climate issue is intensely political. The hardened denialists look to me to be driven mostly by political motives about corporate freedom and small government etc, and these positions are rigid positions they are reluctant to change. They resent any laws that define how companies process information. I see all this sort of thing in numerous comments on other websites.
I havent seen a proper study on it, but I'm willing to bet serious money I'm right. This has to be faced for what it is. This website acknowledges the problem but may be clouding it with too many other lesser things at times.
I'm not sure how you convince such rigid people, however I do believe they tend to be in a minority, and just make a lot of noise.

"The links to the XOM articles, studies, etc are not easily accessible"
What exactly does this mean? Be precise. Nobody else has complained of difficulties. Not even Exxon is actually denying that they produced a large volume of research confirming that we are warming the climate, so your exercise is somewhat pedantic.
"A total of 187 papers, articles, studies, etc seems to be an extremely small sample of the total volume of work and internal documents generated by ExxonMobil, Given the size of Exxon Mobil, most would have expected a much larger sample"
I disagree. You are making a false comparison. The correct comparison would be whether 187 climate studies is a represenative sample of total climate studies, not all internal documents. 187 climate studies would seem a lot of climate studies by any standard.
Also, the Oreskes study doesn't appear to mention anything about using a random sample as such. They simply stated that they used all the publicly available information they could find. I think its safe to assume anything that Exxon tried to hide would not be flattering to them and I doubt Orekses would have been selective, because Exxon would certainly be in a position to easily embarrass them and would quickly do so.

It is my sad duty to inform you that RockyTom AKA Tom Farmer has passed away after a long illness. It is my understanding that Volume 2 was about complete and I hope that Springer will allow the book to be published.

Before we jump to conclusions regarding the validity of this study, a few observations
1) The links to the XOM articles, studies, etc are not easily accessible which makes it difficult to independently ascertain if the classification of the position of each individual paper is a reasonable classification of the position of such paper, ie is the classification assigned a reasonable classification, since it is difficult to link to and subsequently read the article, it is difficult to ascertain the reasonableness of the classification,
2) A total of 187 papers, articles, studies, etc seems to be an extremely small sample of the total volume of work and internal documents generated by ExxonMobil, Given the size of Exxon Mobil, most would have expected a much larger sample
3) As noted in #2 above, the sample size is exceedingly small. Was there ex-post screening to the papers used in this classification study. -

This seems a rehash of old news. A couple of years ago, there were reports that Exxon had both admitted climate change was real, and that they had as early as ( and since) 1981 engaged in disinformation on the topic. Right?
Only recently have they changed their stance on the science.

RedBaron at 02:05 AM on 25 August 2017Harvard scientists took Exxon’s challenge; found it using the tobacco playbook
Ironically I called Exxon up quite a long time ago. I explained how them supporting my research as part of Oklahoma's Carbon Project would be cost effective. How it has the potential of avoiding these huge legal and public trust problems before they even become an issue. The cheapest investment they ever thought about making. Very similar to when the big insurance agencies invested in timberland years back to hedge their bets, except Exxon wouldn't need to buy those millions of acres of farmland, just support in the training of new farmers to help mitigate AGW. Total cost to them basically less than their petty cash funds. Probably less than their advertising campaign for a day. Certainly a gazillion times cheaper than their law firm retaining fees to fend off lawsuites for being financially, socially and ecologically irresponcible. ie bad citizens
...
The arrogance and ignorance I found from their so called "citizenship" division was incredible. Starting with that as an example and considering any company would put their best foot forward in a "citizenship" division ... No wonder they continually make such blunders. It's like they are purposely trying to do the worst possible thing.

Nigelj:
A primary difference with Exxon lying about Cimate Change to their stock holders is that it is against the law. AGW will reduce the future profits of oil companies (and therefor reduce the stock proce) and it is fraud for them to hide problems like that from the market. Already coal company investors have lost their shirts.
Cigarette company lies only resulted in consumers deaths, not monetary losses for stockholders (in fact stockholders benefited from the fraud). The law strictly protects stockholders from fraud, consumers have to protect themselves.

The behaviour of Exxon has been appalling, but the sad reality is not everyone cares. Some people think companies should be free to do and say what they like. Plenty of climate denialists I have come across have this attitude either out of self punishing stupidity or extreme self interest, and these opposites happily cohabit the denialosphere.

"and people complained about fuel being burned from airplane travel (however the airplane prevents solar enery from entering the sea or ground by casting a shadow - quite a few kWh)."
Aircraft emit approx. 1% of global CO2 emissions (plus other greenhouse gases) so are responsible for a small but measurable and significant quantity of warming.
There are typically 9,000 aircraft in the air globally at any one time. The area of total shadow cast is approximately 1 part in 30 million of global surface area. Therefore the shadow effect on surface temperatures is totally insignificant.

The enormous amount of work that has gone into this site is still breathtaking every time I visit. I can't find a way to express my thanks to all the contributors throughout the years in an appropriate wording. But I hope you'll get the gist...

Well I have learned a bit of the more sophisticated information from Skeptical Science posts. I must say that some of the scientists (not necessarily from Skeptical Science) have come up with ideas that have problems. People found that cool roofs reflected solar energy onto other buildings and increased air pollution and decreased rain because of lack of convection. Cows were accused of grand methane production and harm (however if the cows do not eat vegetation it can rot anyway, causing carbon dioxide and methane). and people complained about fuel being burned from airplane travel (however the airplane prevents solar enery from entering the sea or ground by casting a shadow - quite a few kWh). Scientists have proposed bright clouds, but with evaporative fine mist cooling, temperatures of clouds could fall to near wet bulb temperatures and descend (or have they got a method to make them rise?). Putting aerosols into the air will also (I am almost certain) reduce solar energy to the ground and reduce convectional rain, causing droughts. So it seems to me that some solutions proposed to cure the situation will cause problems. But huge headway has been made with solar energy (solar panels), wind energy, etc. Used solar panels have now become a huge problem - where to put them. My proposal is this: Make mirrors (mirrors can be made with plastic) of old solar panels and use them for concentrated solar power.

MA Rodger at 19:50 PM on 23 August 2017Solar eclipse: Why the sun is not responsible for recent climate change
chrisd3 @3,
The RealClimate problem post on stratospheric cooling was actually one of the launch posts for the site back in 2004 and was edited more than once before being replaced and declared "obsolete and wrong in many respects." There is a SkS post explaining why increased GHGs result in stratospheric cooling (a post which I see also underwent post-publication revisions). The reason why stratospheric cooling is being mentioned here because there are other factors affecting stratospheric temperature including TSI. This added complication allows the denialist message to create a fair amount of garbled nonsense on the subject, a process which actually itself causes increasing heat within the the deniosphere. Mind, while the deniosphere may relish the occasion of the likes of RealClimate or SkS admitting a message is wrong, their position is really one of the mucky old pot calling the smirror-finish electric kettle black.
As for attributing the cooling of the stratosphere, you need to set out the reference from which the cooling is measured (and we become off-topic). Over decades, the CO2 cooling effect (or 'effects' - it is not a simple process) has been larger than the CFC/ozone cooling effects (McLandress et al 2014) but more recently it appears the reduced CFC/ozone cooling is apparently pretty-much matching the CO2 cooling (Ferraro et al 2015- [full text]).
