Here's bit on the isotopic evidence of the role than methane clathrates can play in this kind of scenario, the risk is very real.

There are many unknowns with the methane clathrate gun hypothesis, one thing we don't want to find out is we got it wrong in predicting when it goes off and how much methane is released.
Billions of tons of methane being added in pulses to the atmosphere is a nightmare forcing we really don't want to see.
And it's hard to see how some of these deposits are going to remain stable as the temperature continues to climb in critical locations like the Arctic. It has happened before.
Ancient methane 'burp' points to climate change 110 million years ago
"The thawing of the so-called methane hydrates coincides with a period of warming following a volcanic eruption, which released a cloud of carbon dioxide into the atmosphere.
"That was when Earth transitioned from a cold climate to a warm climate," Grasby said.
"So we see this sudden and short term release of methane is coincident with this period of global climate warming.""
There's some question about how much of this methane would get into the atmosphere, but there is also isotopic evidence that methane pulses have played a significant role in previous rapid warming periods that have resulted in extinction level events like the End Permian.

MAR @7, thank's, but it wasn't that research. I remember now it was this article on page 22 as follows:
Fasullo and Trenberth found that the climate models that
most accurately capture observed relative humidity
in the tropics and subtropics and associated clouds
were among those with a higher sensitivity of
around 4°C. 64 Sherwood et al. also found a
sensitivity figure of greater than 3°C.65 Zhai et al.
found that climate models that are consistent with
the observed seasonal variation of low-altitude
marine clouds have an average sensitivity of
3.9°C. 66 Recently it has been demonstrated the
models that best capture current conditions have
a mean value of 3.7°C compared to 3.1°C by the
raw model projections.67 -

A most interesting analysis but possibly of acedemic interest. If we trigger a tipping point, all bets are off. The one we seem to be most worried about at present is starting to release the huge reserves of methane locked in clathrates. Indeed, this seems to be under way in the Arctic both on land and sea bottom. At some point this is likely to become self perpetuating and some research suggests that such an event in the past led to sudden and extreme changes in the climate. It has now been 55m years since the PETM so lots of time for clathrates to have accumulated. Since there seems no reasonable chance that we will significantly reduce our carbon output any time soon, we are pushing this experiment to the limit.

1. I'm not looking at a bleak future, I'm looking at a very disturbing present, catastrophic climate change isn't soemthing that is going to hit at some undefined point in the distant future it is here now. What does an almost complete loss of coral reef systems alone mean to an overall ecological integrity, something that is almost inevitable now with the decades of warming already locked in with the CO2 we've already emitted. Every extra year of emissions is locking in futher warming years down the road. I'm very concerned about what is already happening with a full expectation it will get much worse even if we fundamentally changed course today which we have not.
2. I'm going by what researchers like James Hansen have to say and acknowledging that much of research is conservative when compared to what we are actually seeing in a real world response. Whether it is ice loss, changing climate patterns and more. And some of them have made it clear they expect far more warming than the current predictions are estimating.
3. As long as we are emitting billions of tons of CO2 a year the positive forcing will continue, some nations like the one I live in are still projecting decades of large scale fossil fuel use. The Canadian federal government just spent $4.5 billion dollars to buy a dilbit pipeline to enable a tripling of capacity of this one line of one of the most carbon intensive fossil fuels there is, oil sands bitumen. There is not going to be any leveling off of the radiative forcing of CO2 as long as we are rapidly increasing atmospheric levels of CO2 by burning fuels like oil sands bitumen. And the lag in ocean warming means that the CO2 we emit today is not going to be rebalanced for decades.
4. It's not sea level rise that is going to set a long term limit on human forved climate change, it is going to be a thermal equilibrium in the oceans that will take centuries to establish based on the radiative forcing we have already created. The oceans are the main driver for climate and the main mechanism to move heat around the planet. This means there will be no such thing as stable weather and climatic conditions until this adjustment is completed. That alone is going to be a major stressor on people and entire biotas for those centuries.
We are messing with one of the fundamental factors that makes life possible on Earth in a way that assumes we are in control of this incedibly powerful mechanism.
I see no signs at all we are, the only choice we have now is how far we are willing to push it to cross tipping points some of which we almost certainly have not been able to define in any meaningful way yet.
It's Russian Roulette on a planetary scale, so yes, I am very concerned.

SteveS at 01:50 AM on 26 September 2018Volcanoes emit more CO2 than humans
Umm, 18,000 tons * 365 days is 6.6 million tons, not billion. You're off by a factor of 1000. So Katla gives off ~0.02% of what humans do.
-
Teddz at 01:18 AM on 26 September 2018Volcanoes emit more CO2 than humans
It's suggested here that man's contribution is about 30bn tons of CO2 annually. The Climate.gov website estimates it at 40bn tons.
The Katla volcano is currently out gassing at a rate of between 12 and 24 ktn a day. That equates to a mid range (18ktn) figure of 6.5bn tons a year. That's about 17% of what man's contributing.
It should get quite warm next year?
Moderator Response:[DB] As has already been noted, your statements and maths are erroneous.
Per NOAA, and Burton et al 2013 (which subsumes the works of Gerlach 2011), human activities produce more than 60 times the amount of CO2 than do all the volcanoes in the world, combined.

SirCharles,
It is undeniable that non-profitable removal of CO2 from the atmosphere, starting now, will be required to limit the harm done to the future of humanity.
The more important understanding is that minimizing the harm done to the future of humanity by the 'people pursuing the Best Possible Present for Themselves any way they can get away with' will require a significant correction of the incorrectly developed socioeconomic-political games that people play.
If the systems are not corrected the developed results will be more harmful to the future of humanity, and in many more ways that the impacts of the production of excess CO2 from the burning up of non-renewable buried ancient hydrocarbons.
A caring and considerate portion of the population will not be able to overcome the damage done by 'those who care less and can get a competitive advantage in the competitions to appear to be superior relative to others by behaving less responsibly (more harmfully)'.
The systems need to change in ways that ensure that 'improved awareness and understanding of what is going on and the application of that knowledge to develop a sustainable and improving future for humanity' Governs the actions of everyone (the key part of the word Government).
And the thing that pursuers of personal liberty and smaller government appear to deliberately fail to understand is that 'the more people who self-govern more altruistically, the smaller the Government (the collective actions to limit the people who do not responsibly self-govern) will need to be'. And that increased proportion of altruistic power and wealth has to happen first - only then can Government get smaller. And until that imrpoved behaviour occurs in the general population and business world, the Government (of the people, by the people, for the people) must be ruled by caring, considerate, thoughtful altruistic people responsibly limiting what is gotten away with in the games people play.
Right now many of the supposedly most advanced nations are struggling to have the type of leadership that the future of humanity clearly requires. Some of the less developed nations appear to be getting more responsible leadership.

MA Rodger at 20:25 PM on 25 September 2018New study reconciles a dispute about how fast global warming will happen
Doug_C @1,
The bleak future you paint for AGW is not one I see.
♦ Firstly, "a +3.4ºC warmer Earth" mentioned in the OP says its based on this which is the projected warming if we restrict our mitigation to 'current policies'. As the world ramps up its mitigation, that projected value will drop.
♦ Secondly, you do not set out the "current understanding" which you say demonstrates a possible +12ºC world. I am not aware of research that shows such warming (without unmitigated emissions continuing). Mind, I would add that there is much research to suggest that "a +3.4ºC warmer Earth" would come with added bonus warming from natural feedbacks which science cannot/doesn't yet quantify and even if there were no added bonus warming, "a +3.4ºC warmer Earth" is still not a good place to be.
♦ Thirdly, when it comes to that "stable balance" in global temperatures at the end of the AGW process, the forcing from CO2 & other GHGs will be in decline well before we reach the equilibrium temperature of our peak forcing. Indeed, with zero emissions the forcing level will be dropping fast enough to pretty-much cancel-out temperature rise. (Note, we will still be left with half our CO2 and thus more than half our CO2-forcing at the end of the coming millenium unless future generations act the reduce it further.)
♦ Fourthly, it is probably the sea-level rise that sets a limit for long-term AGW. I am always a bit pigged-off by SLR being only projected to 2100 rather than shown on a multi-century basis. IPCC AR5 SPM E.6 doesn't once countenance the problems of SLR post-2100. You have to dig a lot deeper to see what lies in store. You find Fig IPCC AR5 Fig 13.14 (pasted below) showing that even a +1.0ºC warmer Earth will experience multi-metre SLR which our decendants may prefer not to experience. (In 13.14, the left-hand graphics are 'multi-millenual', the right-hand SLR after 2000 years, respectively for thermal expansion, glaciers, Greenland, Antarctica, total.) And note the 7-metre rise caused by Greenland going into melt-down in a +1.5ºC world, a process which will become irreversible if it gets the chance. AR5 rather plays down the chances of any surprises from Antarctica in a sub+4.0ºC world but the message from Greenland is shocking enough.

nigelj at 14:35 PM on 25 September 2018New study reconciles a dispute about how fast global warming will happen
I agree volcanic activity is clearly not responsible for the modern global warming period. It could only be implicated in the recent global warming period if there was some substantial change in volcanic activity in recent decades compared to earlier decades. Given the quantities of CO2 emitted by volcanoes are quite small compared to human emissions, according to sources mentioned above, there would need to be a very substantial and obvious change.
A quick look at "list of large volcanic eruptions of the 20th century" on wikipedia shows no obvious change in activity between the early part of the 20th century, and the part after 1975 when the "modern" warming period related strongly to CO2 emissions started. Ditto theres no difference in volcanic activity overall between the 19th and 20th centuries. Yes its eyeballing a list but that is sufficient in this case.
This is reasonably basic detective work, so the fact that the "denialists" don't register it looks like wilful ignorance to me in many cases. Head in the sand stuff. I'm so sick and tired of it. We should be able to have grown up conversation with this obvious material on the table, and not disputed and ignored. I'm all for genuine scepticism if its intelligent and evidence based, but I haven't seen any for years now.

One Planet Only Forever at 08:38 AM on 25 September 2018New study reconciles a dispute about how fast global warming will happen
The aspirational objective of only 1.5 C warming is a key point of the Paris Agreement.
Leaving CO2 at the level that results in 2 C warming is unacceptable. And the lack of responsible leadership means that it is highly likely that non-profitable actions to sustainably remove CO2 from the atmosphere will be required (more if the impacts exceed the 2 C limit.
Since it is already unfair to impose the challenges of climate change on future generations (even unfair to impose 1.5 C impact), the current generation should be obliged to start un-profitably removing CO2 from the atmosphere, and back-tax the people who got wealthy undeservingly as much as possible to pay for what undeniably needs to start to be done.
It needs to be clear that wealth will be removed from people who benefit from the burning of fossil fuels to correct the harm done. That way the entire issue is in 'Their' hands. They want more wealth from the production of more excess CO2? They can only have what is left after paying to remove excess CO2.
Making the people who benefit from a harmful activity understand that they will be the ones to pay to fully neutralize the impacts of their pursuits, pro-rated by how much benefit they personally get, appears to be the only way those people will 'get the message'.

Doug_C at 08:31 AM on 25 September 2018New study reconciles a dispute about how fast global warming will happen
The simple fact is we are emitting massive amounts of the primary persistent greenhouse gas into the atmosphere every year and some are still trying to find ever more convoluted ways to justify this.
Are Volcanoes or Humans Harder on the Atmosphere?
"This argument that human-caused carbon emissions are merely a drop in the bucket compared to greenhouse gases generated by volcanoes has been making its way around the rumor mill for years. And while it may sound plausible, the science just doesn’t back it up.
According to the U.S. Geological Survey (USGS), the world’s volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes comprise less than one percent of those generated by today’s human endeavors."
If there was a supervolcano or a massive flood basalt somewhere on the Earth's surface would we be debating at all the catastrophic impacts of it emitting 100 times the average amount of CO2 from tectonic activity every year.
We'd be preparing for the same kind of massive die-offs that the geological record indictates are associated with similar events like this in the past.
Something we are already beginning to see on a large scale when you consider the massive and rapid die-offs on the Great Barrier Reef alone.
This is a supervolcano we can shut of and in fact be much better for in terms of air quality, ecological integrity and financial cost.
The Data Says Climate Change Could Cost Investors Trillions
"If we stay on the current emissions path, the study predicts, the value at risk in global portfolios could range from about $2 trillion to $25 trillion. In a bit of understatement, Simon Dietz of the London School of Economics, the lead author of the report, told The Guardian, “long-term investors…would be better off in a low-carbon world.”
Estimates of climate risk in the trillions are unfortunately getting more common. Last year, Citi produced a powerful study of the costs and benefits of shifting the energy system toward low-carbon technologies. Unchecked climate change, Citi said, could cost the world $72 trillion by the middle of the century. But the big surprise in Citi’s report was the cost of building the low-carbon economy: the world can spend $2 trillion less in total on energy infrastructure and ongoing fuel costs than it would in the business-as-usual scenario. So we save $2 trillion and avoid losing up to $72 trillion in economic activity."
Fossil fuels are a lose-lose no matter how contrarians still try and load the dice in the favour of the fossil fuel sector by consistently downplaying the likely impacts of the continued emissions of tens of billions of tons of CO2 a year.

nigelj at 06:56 AM on 25 September 2018New study reconciles a dispute about how fast global warming will happen
I was thinking something similar to Doug C. We think in terms of warming projections by the year 2100, but its rather an arbitrary date related to our own lifetimes. This is natural of course, but I think its the next 1 - 5 centuries that are crucial for humanity as a whole if one thinks in a futurist sense. Firstly its this period of about 1- 5 centuries where the full results of climate sensitivity (and climate tipping points) will be felt with sea level rise and full development of temperatures and their various consequences.
Secondly the planet is going through a population demographic transition where the most likely track will be the current 7.6 billion people increasing to 11 billion by the year 2100, then population levelling off or possibly falling very slowly. (refer projections of population growth on wikipedia). The point is a huge population bulge of about 11 billion people from perhaps about 2100 - 2500 seems likely and will coincide with the unfolding of the worst climate impacts. Of course this is a trend based on family size, and climate change itself could well become so catastrophic that it forces population down through significantly increased mortality. Either way, its an existential threat.
I recall reading that climate models that have best predicted the trends with clouds have high climate sensitivity. Sorry tried to find the source article but couldn't.

Doug_C at 03:11 AM on 25 September 2018New study reconciles a dispute about how fast global warming will happen
2100 isn't the endpoint, we need to be looking at where the Earth will enter into a stable balance again.
With the feedbacks that will almost certainly result from a +3.4 Celsius increase by 2100, how much warmer will the Earth become after that.
The inpacts of a +3.4 C warmer Earth will be catastrophic to most life here, what if that carries through to a +12 C Earth or worse which is also possible with our current understanding.
That will kill off all complex life on Earth taking us back to a time dominated by bacteria and viruses.
The contrarians are almost certainly the most inaccurate at predicting outcomes with climate change because they look at the data as something to contradict not genuinely analyze.

ChezProvence: Furthermore, the head-line and sub-headline of the SA article do not comport with the facts set forth in the first three paragraphs of the article:
California coastal cities should be prepared for the possibility that oceans will rise more than 10 feet by 2100 and submerge parts of beach towns, the state Coastal Commission warns in new draft guidance.
The powerful agency, which oversees most development along 1,100 miles of coast, will consider approving the guidance this fall. A staff report recommending the changes was released last week.
Earlier commission guidance put top sea-level rise at 6 feet by 2100. But according to the new report, there’s the “potential for rapid ice loss to result in an extreme scenario of 10.2 feet of sea level rise” by the end of the century.

nigelj,
There are a variety of definitions of propaganda (and advertising). And propaganda does not have to be misleading or harmful.
My 1985 edition of The Concise Oxford Dictionary defies propaganda as: association or organized scheme for propagation of a doctrine or practice; or doctrines, information, etc., thus propagated.
Merriam-Webster On-Line Dictionary currently defines it as: the spreading of ideas, information, or rumor for the purpose of helping or injuring an institution, a cause, or a person; or ideas, facts, or allegations spread deliberately to further one's cause or to damage an opposing cause.
And if it is Capitalized it is: a congregation of the Roman curia having jurisdiction over missionary territories and related institutions
So, in the minds of many, propaganda has only negative connotations. But that is a recent development. And it is not a fair re-definition since propaganda can be helpful to the development of a sustainable better future for humanity, but such helpful propaganda from elected leaders can be easily attacked by simply unfairly declaring it to be propaganda.

I also dislike misleading rhetoric intensely. It has always been a part of advertising and general debate, but it seems to have increased in volume in recent years, or maybe I'm just getting old and noticing it more or something. But perhaps the advent of talkback radio and then the internet has amplified it, given it a huge platform in both general discussion and debate, and in advertising and marketing. This has changed the landscape, and demands a response and better awareness of the problem.
I think misleading rhetoric is almost as bad as lying. Its a way people have developed to hide information that stops just short of lying, so they can't be accused of lying. Yet to me its just as unacceptable, assumimg its deliberate or cynical of course.
Propaganda is formally defined as political information that is often misleading or one sided. I dont think I could ever call propaganda acceptable, but I agee that advertising is not always a problem, its entirely dependent on how its structured. But then most countries have laws to deal with misleading advertising, and in fact I lodged a complaint once, and the advertisement was removed from television.
But we don't deal with misleading rhetoric in public discussion so well. I suppose free speech is paramount, but I can only hope for spreading better awareness of the nature and unacceptability of misleading rhetoric and shaming people into using more open and transparent debate.

ChezProvence at 04:01 AM on 24 September 2018Sea level rise is exaggerated
I started at about post #7 with sea level rising at 2.46 mm per year. Eight years later, that may be 3 mm per year (3.46 +/- 0.4) or so ... so about 0.1 in per year ... less than a foot by 2100.
California has accepted a new building code, expecting 10 feet by 2100.
Does this make any sense? Should we all be investing in Dutch dike companies?
Moderator Response:[DB] And yet, per Nerem et al 2018:
"Global sea level rise is not cruising along at a steady 3 mm per year, it's accelerating a little every year, like a driver merging onto a highway, according to a powerful new assessment led by CIRES Fellow Steve Nerem. He and his colleagues harnessed 25 years of satellite data to calculate that the rate is increasing by about 0.08 mm/year every year—which could mean an annual rate of sea level rise of 10 mm/year, or even more, by 2100."
"This acceleration, driven mainly by accelerated melting in Greenland and Antarctica, has the potential to double the total sea level rise by 2100 as compared to projections that assume a constant rate—to more than 60 cm instead of about 30." said Nerem, who is also a professor of Aerospace Engineering Sciences at the University of Colorado Boulder. "And this is almost certainly a conservative estimate," he added. "Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. Given the large changes we are seeing in the ice sheets today, that's not likely."
And:
"the observed acceleration will more than double the amount of sea-level rise by 2100 compared with the current rate of sea-level rise continuing unchanged. This projection of future sea-level rise is based only on the satellite-observed changes over the last 25 y, assuming that sea level changes similarly in the future. If sea level begins changing more rapidly, for example due to rapid changes in ice sheet dynamics, then this simple extrapolation will likely represent a conservative lower bound on future sea-level change."

John Hartz,
On further reflection I am addressing any marketing efforts.
Advertising and propagada actually have no clear definitions. They can be done to raise awareness or to fool people into wanting or believing something. They can be more understanding/fact-based or more emotional/desire appealing. They can be political or business related. Anyone can believe whatever they want the terms to mean (but Nasi use of the term propaganda definitely still taints perceptions of the term).
My focus is on distinguishing acceptable vs. unacceptable, based on a Governing Objective of improving awareness and understanding and applying that knowledge to develop a sustainable better future for huamnity. And I consider the Sustainable Development Goals and other UN agreements (like nuclear non-proliferation, and Human Rights) to be sub-objectives aligned with that Governing Objective.
It would probably be better to use a term like "promotion efforts" when identifying that the important distinction is how helpful they are, with an added understanding that less factual but helpful promotion efforts are not really OK either. The acceptability is a combination of helpfulness to the development of a sustainable better future for humanity and being based on the improved awareness and understanding that has developed (something sounding helpful but not properly based on the constantly improving awareness and understanding needs to be updated/corrected).

One Planet Only Forever at 00:49 AM on 24 September 2018Shell and Exxon's secret 1980s climate change warnings
I would add that I am not really a fan of deliberately misleading messages as part of a government propaganda program, even if the result would be more helpful behaviour of the people influenced by the propaganda.
Early propagada campaigna against Pot in Canada are an example. Discouraging the use of Pot is helpful, especially dicouraging it among younger people, but the campaign was a dismal failure because it was so grossly inaccurate. The new Pot propaganda campaigns in Canada are entertaining appeals for people to not toke and drive, and avoid combining pot with tobacco because of the effects of combined use.
And propaganda is government marketing. Governments do not advertise.
-
One Planet Only Forever at 00:41 AM on 24 September 2018Shell and Exxon's secret 1980s climate change warnings
My definition is the simple use of emotional appeal to popularize a message. And I admit the eveolved concept of the term has been severely tainted by the Nasi use of Propaganda.
So my distinction is that propaganda for harmful intent is unacceptable, especially if the emotional appeal is combined with a deliberately misleading message.

"Oil is produced because we demand it. Private oil companies exist only because of the world's voracious demand, and if they went 'Poof' tomorrow state owned entities would expand to replace them, albeit with higher overhead.
Most of the world refuses to allow their government to dictate how much energy they consume in the form of food, manufactured products, heated, cooled or humidity controlled homes and asphalt on their roads, and the freight network that hoves all that supports civilization. When we demand these things by buying them, we cause oil to be extracted, transported and refined."
Oil and all fossil fuels aren't being used on a massive level because the public keeps demanding it, they are still the main source of energy for two key reasons.
1. A decadal and massively funded campaign on the part of the fossil fuel sector to deny the inherent risks in using fossil fuels on a massive scale.
2. Huge amounts of money spent to lobby politicians by the fossil fuel sector.
Lets look at British Columbia alone where I am now.
$5.2 million in political donations and more than 22,000 lobbying contacts
In an 8 year period the oil and gas sector paid politicians in BC alone $5.2 million and lobbyed them 22,000 times that's an average of 14 times a day.
These are products that we know are highly dangerous to keep using at the current scale, the only reason we are still on a course to imminent disaster with fossil fuels is because we are being held there firmly by the fossil fuel sector itself which has effectively captured regulators like the Nation Energy Board of Canada.
The courts here have ruled that our national energy regulator is captured by the fossil fuel sector.

Advertising and propaganda are not a problem. The problem is people being harmfully misleading, especially with appeals built to trigger myopic worldview primal human selfish reactions to overwhelm reasonable thoughtful altruistic modern human consideration.
And the governing objectives of acceptable leadership action need to be understood to be the promotion of improved awareness and understanding of what is really going on (the latest climate science, or any other learning), and the application of that knowledge to improve and achieve the Sustainable Development Goals.
Without that improved awareness and understanding, a society or organization has no real future. And government advertising and propaganda should be legally required to promote that awareness and understanding - for the good of the future, because the free-market certainly cannot be expected to do it.

One obvious (for William) example would be the NZ Electoral Finance Act 2007 repealed after only two years with a vote 112/9. Nonetheless, NZ does make it more difficult for corporations to buy elections. You can tell if a democracy is in trouble if you have lobbyists talking directly to politicians (buying favours via campaign funding) instead of trying to influence the electorate.

nigelj @4,
The article you link-to is based on Steffen et al (2018) 'Trajectories of the Earth System in the Anthropocene' which, even with Schellnhuber as a co-author, doesn't provide a list of tipping points projected for +1.5-2.0ºC. The source of the Fyson & Rahmstorf quotes @1 appears to be this web page which does lists five tipping points, referencing a graphic presented within a YouTube video which is Fig 1 from Schellnhuber et al (2016) 'Why the right climate target was agreed in Paris'. This Fig 1 does show thirteen 'tipping points' (if you can call them that), of which five begin to 'tip' below 2.0ºC with one of them entirely 'tipping' below 2.0ºC.

William @5, the problem with making it illegal to fund any politician privately is that it entrenches the existing politicians. If nobody has any advertising funding except for the current politicians (or parties), then voting for anyone else would be playing roulette.
I agree that you have identified a big problem, but not with the solution. There is a saying "For every complex problem there is a simple solution, which doesn't work".

Driving by @6
Strawman arguments about companies not making oil, dubious comparisons between a single company and entire countries, stating things everyone knows anyway.
In addition, it doesn't matter what exonn does or manufactures, that doesn't absolve them of blame for concealing research on climate change from the public. Nobody is above good ethical standards or consumer law, are they?
Plus omission of obvious facts and cynical lack of balance. We don't have to just "stop using oil" and become hippies :) There are alternatives to not using oil such as renewable energy.

Oil companies such as Exxon do not create oil, nor are they the great producers. That would be Saudi Arabia, Venezuela, Mexico and the rest of OPEC. The oil companies merely respond to demand by doing the in-between work of buying, transporting, stockpiling and in some cases refining. Some oil is extracted by the major oil componies, but few (none?) equal the scale and output of Saudi Aramco, Pemex or PDVSA. OK, post Chavez PDVSA isn't producing as much oil, but that's not due to any environmental enlightenment. China may well muscle in and flip that condition.
The whole post cleverly tosses aside something more fundamental: Oil is produced because we demand it. Private oil companies exist only because of the world's voracious demand, and if they went 'Poof' tomorrow state owned entities would expand to replace them, albeit with higher overhead.
Most of the world refuses to allow their government to dictate how much energy they consume in the form of food, manufactured products, heated, cooled or humidity controlled homes and asphalt on their roads, and the freight network that hoves all that supports civilization. When we demand these things by buying them, we cause oil to be extracted, transported and refined. To not use oil one drop out of society and exist on animal and hand power.
It would be nice if suddenly the world's population decided to do as we see fit and not use products, services or forms of energy produced by fossil fuel. People say they would like to do so, but almost no one outside people reading sites like this (maybe 0.5% of the world, if that) will follow up.
When there's a demand for a product or service, a few people or nations notice and find a way to fulfill that demand. Blaming the providers for doing so implies that you are somehow entitled to direct what people want and what they may exchange their time and toil for. Both the consumers and those who would be the supply to their demand will dissent, and vigorously.

Big companies are amoral. Nothing new here. This applies even to the Pharacutical companies that do give us many life saving products. They also hide negative results of their research as has been revealed many times. The argument by the fuel companies that it is the responsibility of governments to take the necessary measures to protect their people is well taken but the last estimate I have heard, is that there are at least a hundred lobyists in Washington for every politician and the big companies and rich individuals finance political elections. Who pays the piper calls the tune. Until politicians are financed from the exchequer and it is illegal for any person or company to give money for any reason what so ever to a politician, we can forget about them representing us.

I do not have a problem with some people being wealthier than others.
People who have been more helpful regarding the improvement of awareness and understanding of what is really going on and the application of that learning to help develop a sustainable better future for humanity should be more highly regarded and rewarded than others.
The obvious problem is that those type of people are at a competitive disadvantage. People with other interests can easily become bigger winners than they deserve to be, especially when they can abuse the awareness and understanding of the power of misleading marketing to easily tempt people to have a more limited, more myopic, worldview.
Trying to be a winner in ways that are harmful to the future of humanity needs to be treated like current day harmful pursuits of personal perceptions of superiority relative to others. Those actions are discouraged and penalized. We are starting to see that correction occurring. But there is lots of resistance to those corrections by undeserving wealthy and powerful people, especially in supposedly 'more advanced nations', nations, regions, corporations and communities that have only developed unjustified perceptions of superiority relative to others.
For societies and organizations to be truly sustainable, they need to develop higher expectations for helpful behaviour by 'their winners and leaders', and correct or penalize the ones who are 'less deserving of their developed perceptions of superiority'.
Achieving the corrections identified by climate science requires improved awareness and understanding of more than climate science.

The 1987 UN Report "Our Common Future" included the following stetment making it undeniable what the 'winners/leaders' of the time had been doing:
"25. Many present efforts to guard and maintain human progress, to meet human needs, and to realize human ambitions are simply unsustainable - in both the rich and poor nations. They draw too heavily, too quickly, on already overdrawn environmental resource accounts to be affordable far into the future without bankrupting those accounts. They may show profit on the balance sheets of our generation, but our children will inherit the losses. We borrow environmental capital from future generations with no intention or prospect of repaying. They may damn us for our spendthrift ways, but they can never collect on our debt to them. We act as we do because we can get away with it: future generations do not vote; they have no political or financial power; they cannot challenge our decisions.
26. But the results of the present profligacy are rapidly closing the options for future generations. Most of today's decision makers will be dead before the planet feels; the heavier effects of acid precipitation, global warming, ozone depletion, or widespread desertification and species loss. Most of the young voters of today will still be alive. In the Commission's hearings it was the young, those who have the most to lose, who were the harshest critics of the planet's present management."And the success of the fossil fuel industry is the expected result of nations failing to improve the awareness and understanding of their populations. That failure develops myopic worldviews, people caring more about near-term benefits for a small portion of current humanity, caring less about others or longer term interests like the future of humanity.
And how much better are the Winners/Leaders today ---> many are more aggressively regressive.
That failure to responsibly lead the improvement of awareness and understanding, failure to improve and expand worldviews to the future of all of humanity, is exactly what John Stuart Mills warned about in "On Liberty" when he was discussing the ability of the elites (winners) in a society to responsibly educate all members of their society. He stated "If society lets a considerable number of its members grow up mere children, incapable of being acted on by rational consideration of distant motives, society has itself to blame for the consequences."
Societies around the planet have not only failed to be led to improved awareness and understanding, many are developing winners who more aggressively fight against the population developing improved awareness and understanding - and they are still able to get away with it.
In spite of how undeniably harmful to the future of humanity the deliberate misleading of the public regarding climate science actually is, I cannot name a politician who has been brought to trial for deliberately misleading the public regarding climate science, or one that has even just been declared incapable of responsibly performing the duties of their esteemed elected high-office position and been removed from office without having to wait for 'the next election'.
