The size of the prize

https://www.flickr.com/photos/worldtravelandtourismcouncil/13996196945Bjorn Lomborg has a new paper out today in the journal Global Policy. Taking a leaf out of Christopher Monckton's book he assesses the effect that all the policy measures promised at Paris are going to have on global temperatures. As the press release explains this effect is small/tiny/minute/barely discernable:

 

  • ...if we measure the impact of every nation fulfilling every promise by 2030, the total temperature reduction will be 0.048°C (0.086°F) by 2100.
  • Even if we assume that these promises would be extended for another 70 years, there is still little impact: if every nation fulfills every promise by 2030, and continues to fulfill these promises faithfully until the end of the century, and there is no ‘CO₂ leakage’ to non-committed nations, the entirety of the Paris promises will reduce temperature rises by just 0.17°C (0.306°F) by 2100.
  • US climate policies, in the most optimistic circumstances, fully achieved and adhered to throughout the century, will reduce global temperatures by 0.031°C (0.057°F) by 2100.
  • EU climate policies, in the most optimistic circumstances, fully achieved and adhered to throughout the century, will reduce global temperatures by 0.053°C (0.096°F) by 2100.
  • China climate policies, in the most optimistic circumstances, fully achieved and adhered to throughout the century, will reduce global temperatures by 0.048°C (0.086°F) by 2100.
  • The rest of the world’s climate policies, in the most optimistic circumstances, fully achieved and adhered to throughout the century, will reduce global temperatures by 0.036°C (0.064°F) by 2100.

Is that another bout of Lomborg derangement syndrome I hear from our green friends?

The paper should appear here.

So the carbon footprint of holding the global warming party in Paris, is going to exceed the benefits of agreeing to the measures that have already been decided.

Under any definition (apart from FIFA, IAAF, IOC etc), IPPC climate science is not sustainable. What is it about International dopes that attracts so much money, bribery and corruption?

Excellent article. Be good to see it widely distributed.

However, I would like to observe that Mr Lomborg appears to subscribe to the quaint, old fashioned but endlessly debunked notion that there is a measurable relationship between human activity and global temperature.

I suppose it gives him credibility with the fraud deniers.

esmiff; I'm not sure if Lomborg is saying what he means or is being eccenomical with explanation.

The reduction in global temperatures quoted are theoretical only, even if those numbers were the true result, they could never be measured anyway.

Pertinent question : If humans had stopped all CO2 emissions in 1997 what would be the temperature and key catastrophe indicators be today ?

Would the temperature be significantly lower ?
Would ice measurements be significantly higher ?
Would the ocean be significantly more alkaline ?
Would "extreme weather" events be rarer and smaller in size ?

My understanding with CO2 there is no time lag ..a CO2 molecules greenhouse effect should happen shortly after it is released into the atmosphere. Richard Betts ?

I have no difficulty with the overall arguent he presents about the futility (stupidity?) of the obsession with co2 reduction. However In the abstract of the article Bjorn Lomborg says:
‘Current climate policy promises will do little to stabilise the climate and their impact will be undetectable for many decades.’
STABILISE THE CLIMATE
How can he reconcile that idea with climate, chaotic system as described here?
Atmospheric flows exhibit irregular (chaotic) space-time fluctuations on all scales ranging from climate (kilometres-years) to turbulence (millimetres-second) and is a representative example of turbulent fluid flows. Dynamical systems in nature, i.e., systems that change with time, such as fluid flows, heartbeat patterns, spread of infectious diseases, etc., exhibit non-linear (unpredictable) fluctuations.

The thing that is so interesting about this is the light it sheds on the Movement. It has been shown repeatedly that the measures proposed do not in fact achieve the aims which are cited as the reasons for doing them.

In Britain this is very striking. We have first a series of goals in the Climate Change Act, and then we have various measures and proposals which are meant to achieve those goals.

Even if we succeeded in reducing our emissions by 90% from today's levels, which is what the CCA requires, it would have no effect on global temperatures.

This however does not deter The Movement, which seems to think that the force of our example will move the rest of the world to follow suit. Despite the total lack of evidence that anyone pays any attention to our example, and the lack of any publications in the peer reviewed journals to suggest they ever will.

But it then gets worse. Not only will the proposed reductions have no effect on global temperatures (so why are we making them?) but the measures which The Movement advocates so enthusiastically will not make the reductions in the first place. We know by now that wind farms, when fully costed, don't reduce carbon emissions over the same useful delivered electricity supplies as fossil fuel equivalents. We know that when you account for standby evening and night standby power, solar power fully costed will not either.

So we are faced with a movement which advocates doing things to lower our carbon emissions in order to reduce global warming, when the proposals will neither lower our carbon emissions, nor, if they did, do anything to reduce global warming.

And this is assuming the theory is right in the first place. But its important to see that is not the issue. The problem is not that the theory is wrong. The problem is that if it is right, the actions the believers are advocating will be totally ineffective.

Meanwhile, the Movement praises China highly and urges us to follow their example, when the Chinese intention is actually to triple its emissions measured in tons. While lowering them per unit of GDP of course, and still remaining below the US in per capita emissions. This is incomprehensible if people really do believe the theory, but you can read it every other day in the Guardian comments pages and anyone pointing out that the only thing that they are supposed to believe matters is tonnage, and that the Chinese are raising theirs, comes in for a tirade of personal abuse.

It is very difficult to account for how such levels of irrationality and failure to follow simple chains of consequential reasoning can have become so widespread and deeply rooted in public life in Britain. One was tempted to think it was too much literary criticism from all those English degrees, heavily post-modern in orientation. But it seems to have infected people with science and PPE degrees just as much.

This is the real lesson from Lomborg's and others' work on this subject. We are in the middle of a great popular delusion or madness of crowd, and the particular unique thing (to my knowledge) about this one is that those infected first proclaim a pressing danger and then strenously advocate measures which will do nothing about it. I can't think of another case. This time it really is different.

The best guide to the future of the delusion remains 'When Prophecy Fails'. One fears that the longer this goes with no warming, or worse still, if we should experience prolonged cooling, the more ferocious and instransigent the believers will become, and the more strongly they will be committed to their extraordinary policy measures.

If, according to the Telegraph article, "sea level rise corresponding to 2 C would eventually be 4.7 metres" then, after the 1 degree rise we are supposed to have reached, shouldn't sea level rise be now over 2m? Or does nothing happen until you hit the 2 degrees? These people have no logic.

Whatever the nutters and the useful (enviro) idiots believe, this is the main reason every government, every scientist, every science body and every corporation on earth is prepared to lie about global warming.

"Carbon trading could be worth twice that of oil in next decade

The carbon market could become double the size of the vast oil market, according to the new breed of City players who trade greenhouse gas emissions through the EU's emissions trading scheme.

The ETS market may see $3tn (£1.8tn) worth of transactions a year in the next decade or two, according to Andrew Ager, head of emissions trading at Bache Commodities in London, with it even being used as a hedge against falling equities or rising inflation. "It is still a relatively new industry with annual trades of around €300bn every year. But this could grow to around $3tn compared to the $1.5tn market there is for oil," says Ager, who used to be a foreign currencies trader.

The speed of that growth will depend on whether the Copenhagen summit gives a go-ahead for a low-carbon economy, but Ager says whatever happens schemes such as the ETS will expand around the globe".

"London's financial centre is the main home to the incipient global carbon market. Prof Heal believes that in a decade, the trade could be worth trillions of dollars".

When one considers even just for a moment the deeply cynical manipulation by aught and everything interwoven between, energy policy, 'green' anti CO2 legislation and the corporate world, one is left with infinite possibilities and none of it is remotely linked nor, involved to actually: "saving the planet".

We were led up the garden path, think "energy saving light bulbs" - now - Jo and Joanne Public.....in the name of "saving the poley bears" have to purchase inferior products which cost more and whose life expectancy not quite what it promised on the packet. Crikey, what a swindle was that and Philips and Osram laughed all the way to the bank.

Emissions tests, diesel cars and VW - need I say more?

Biofuels, biomass, Nuclear power and building old kit at vastly inflated [stupid money] prices, MORE whirlygigs, PV cells, feed in tariffs, the carbon floor price et bloody cetera, £$€billions creamed off by investment bankers from the taxpayers - in corporate world, it's wet dream time.

And who TF cares in corporate world - if Britain, its energy policy is regressing the nation and shoving it back to the Stone Age?

Saving the planet? CO₂ is a poison? Politicians, they know what's best for YOU? The corporate world is benign and looks after the interests primarily of the consumer and customer? Are we ****ing mad?

This Paris thing - is a joke but I can't say that I find in any way amusing. NGOs will harangue politicians, there will be the usual "woe and thrice woe! are these Pacific islanders - drowning I say. doomed to drowning, DOOMED and its all your fault!" they screech.

Greenpeace will chug round all day, the press will report the 'drama'..ye Gods and wouldn't yer know it. cue.....huh ecstasy........a last gasp deal will be cobbled by Obola and Hollande.
Thus, Obola's mates in GS and in the corporate world will rub their hands in glee, the taxpayers of the western world will pay and do you know what even if a shiny new CO₂ stitch-up is signed - it will do nothing, nada, zilch will ever accrue, except they'll all agree to screw the taxpayer once more - the following year.

Thatcher wasn't the sole cause of the export of jobs, I worked in the British Electronics industry from the early 70s until the 21st century was well under way. It was a classic example of bad management, lack of investment and union intransigence and typical of many British Industries. Thatcher merely cut the death throes short.
I could give you lots of examples of management investing too late and unions making it difficult for it to happen with the net result that the re-war equipment wasn't replaced with anything worthwhile and everyone lost out.

I think Alex Stephens (Stephens Shipyards) is quoted as saying "perhaps I wasn't very good at running a shipyard" in an interview after UCS and that debacle. In my opinion he wasn't alone but one of the few that recognised the fact.

Nov 10, 2015 at 9:33 AM | Unregistered Commenteresmiff

The thing that's really interesting and extraordinary about this is the irrationality of it >b>in its own terms. The reason is that you cannot get there from here.

Suppose climate sensitivity is very high - 6-8C. In that case catastrophe threatens, and you have to dramatically drop emissions immediately. However, because the sensitivity is very high, the drops have to be almost total, every small amount left will have a large effect, which means they are hugely expensive, and so no-one will sign up to them. You have bought urgency at the cost of practicality.

Lomborg's piece shows very clearly how minimal the reductions are that everyone will sign up to. Except the Stakhanovite UK, which has signed up to 90% reductions, but it was 90% of very little, so it doesn't amount to anything much.

Suppose it to be very low - eg 1.5-2C. In that case, there's no rush to start with. But its worse than this from the perspective of action. The effect of any reductions you do make is very small so they are not cost effective. You have bought practicality at the expense of urgency.

What, one wonders, would get out of this dilemma? It comes from the cost of reducing emissions. This is so high that in the one case the scale of the reductions needed is huge and this makes the costs astronomical. In the other case the cost is still high, so the cost compared to the benefits is still too high.

This is why the 'precautionary principle' and other algorithms that have huge catastrophe cost avoidance at their heart are so popular in the rhetoric. The only way you can get there is either raise the costs of inaction or lower the costs of action.

But that depends on what you mean by "worth"!
Where is the money coming from and where is it going? What is the "good" that it is being used to purchase? In metal trading there is a metal; in currency trading there is money; in stocks and shares there is the essential financial underpinning which allows a company to continue operating (or sometimes to put the bullet in its brain). But "emissions"? Why are we allowing people to buy and sell hot air?

Michel,

The first of your comments is excellent. I am on the wrong forum for this but can anyone fault the logic? I am no scientist and realise that I am never likely to understand scientific papers debating whether the theory of AGW is wholly or partly right. I am sure though that the obsession with renewables is nothing more than very expensive virtue signalling. How did we get to this point? We seem to be governed in Europe by people who are incapable of reason.

On carbon capture, cynic though I am, I find it hard to believe that Government energy policies are driven by the wish to establish a lucrative business for industry and the City. In a contest between conspiracy and cock-up I think you are more often right if you back cock-up. In any case carbon capture is only the tail on this highly unattractive dog.

In my view wind power has been shown to be next to useless generally and solar is no use in Northern Europe. They will remain useless unless cost effective large scale storage methods are developed. My reading suggests that at present this is pipe dream.

This doesn't even touch on the fact that, ineffectiveness apart, windmills are polluting machines that blight large tracts of landscape. It is grotesque that anyone who thinks of themselves as an environmentalist can support but they exist in droves - unfortunately.

Excellent post Michel. The thing is the basic sums behind the total ineffectiveness of all the 'action' are trivial and basic commonsense shows how stupid a lot of it is.

Michel -

You escape your dilemma with an assumption that the climate impact is a nonlinear function of temperature increase (aka a climate "tipping point") With this magical invention, you can campaign to lower emissions to any convenient level, and avoid the vice grip of your logic. The beauty of this is that the tipping point can be moved around as needed to create maximum damage...

This is why we hear so much about the importance of keeping warming below 2 degrees celcius. 1.99...no problem, 2...problem...what total BS. Plus, if 2 is not working out from a logic / political perspective, what the heck, all we need is a few high priests to comment, and 1.5 is the new tipping point!

The UN reckons the difference will be much greater. On Oct 30 the BBC quoted UNFCCC Executive Secretary Christiana Figueres as saying that INDC Submissions would constain warming to 2.7C by 2100, as against 4C+ without policy.
That is >1.3°C, as against Lomberg's 0.048°C. The reasons in descending order of importance, I would guess are.
- UN assumes further policy changes post 2030 that few countries have proposed, so whilst in 2030 emissions will be 10-20% higher than in 2010, by 2030 they will be significantly lower.
- UN assumes all policy proposals will be carried out in full. Including in the EU or the USA?
- UN BAU scenario is a bit high.

I wonder if our politicians have revised the Climate Change Act in the light of the new lower UNEP 2020 target?

UN report raises ceiling for greenhouse gas pollution, calls previous assessments unrealistic

"....The U.N.'s environmental authority has quietly raised its assessment of the level at which global greenhouse gas emissions must peak to avoid dangerous climate change, as governments seek a new accord to fight global warming.

In its first four annual emissions reports in 2010-2013, the United Nations Environment Program said emissions must not exceed 44 billion tons in 2020 for the world to limit global warming to 2 degrees C (3.6 degrees F).

But with real-world emissions rising far beyond that level, UNEP has since last year downplayed its focus on 2020 as a make-or-break year for emissions reductions.

In this year's Emissions Gap report, a summary of which was released Friday, UNEP says the world can still reach the 2-degree target with emissions of 52 billion tons by 2020, which is just slightly below today's level........."

Size of the prize indeed:

++++
The Global Commission on the Economy and Climate recommends that all developed and emerging economies, and others where possible, commit to introducing or strengthening carbon pricing by 2020, and should phase out fossil fuel subsidies.

Governments should integrate carbon pricing into broader fiscal reform strategies, prioritising the use of resulting revenues to offset impacts on low-income households and for other productive uses such as reducing other distortionary taxes.

G20 governments or coalitions of willing governments should work together to enhance efficiency and minimise competitiveness concerns, building on existing peer-review processes and reporting annually on progress.
All major businesses should adopt internal carbon prices and actively support carbon pricing policy.

A carbon price in 2030 of US$75 per tonne of CO2e in developed countries and US$35 per tonne of CO2e in developing countries, on average, could see annual emissions in 2030 reduced by 2.8–5.6 Gt of CO2e.

Something which deserved a bit more publicity than it seemed to have got is a series of pre-Paris talks/discussions at the Cato Institute on 30th October.

The first panel, on the science was probably the least interesting (to me) because of the familiarity with the subject matter. I found the later panels considering the legal and technical aspects of what to expect was the most interesting, and Richard Tol's talk was the most enjoyable. Many of the discussions are from a US viewpoint but it all seems relevant.

Lomborg may have the magnitude of the effect of suppressing the greening gas about right or still too big.

As anyone who really groks classical physics should come to realize , spectral phenomena cannot "trap" energy . The bottoms of atmospheres are warmer than there tops by the easily calculated difference in the gravitational energy .

Our surface temperature has more to do with the molecular weight of CO2 than its spectrum which at any life sustaining levels has only a minuscule effect on our spectrum as seen from the outside which determines our radiative balance with the outside .

not banned yet, the Russians are getting annoyed about questions being asked about the prizes they won in London 2012.

In a tit for tat response, they might ask more questions about prizes and attributions in climate science.

Bribery and corruption in football and sport generates huge amounts of media and public interest, but the media seem quite happy with climate science, thinking the IPCC is a good independent referee.
