Climate Sensitivity Reconsidered

Final climate sensitivity

Substituting in Eqn. (1) the revised values derived for the three factors in ΔTλ, our re-evaluated central estimate of climate sensitivity is their product –

ΔTλΔF2x κ f ≈ 1.135 x 0.242 x 2.095 ≈ 0.58 °K (30)

Theoretically, empirically, and in the literature that we have extensively cited, each of the values we have chosen as our central estimate is arguably more justifiable – and is certainly no less justifiable – than the substantially higher value selected by the IPCC. Accordingly, it is very likely that in response to a doubling of pre-industrial carbon dioxide concentration TS will rise not by the 3.26 °K suggested by the IPCC, but by <1 °K.


We have set out and then critically examined a detailed account of the IPCC's method of evaluating climate sensitivity. We have made explicit the identities, interrelations, and values of the key variables, many of which the IPCC does not explicitly describe or quantify. The IPCC's method does not provide a secure basis for policy-relevant conclusions. We now summarize some of its defects.

The IPCC's methodology relies unduly – indeed, almost exclusively – upon numerical analysis, even where the outputs of the models upon which it so heavily relies are manifestly and significantly at variance with theory or observation or both. Modeled projections such as those upon which the IPCC's entire case rests have long been proven impossible when applied to mathematically-chaotic objects, such as the climate, whose initial state can never be determined to a sufficient precision. For a similar reason, those of the IPCC's conclusions that are founded on probability distributions in the chaotic climate object are unsafe.

Not one of the key variables necessary to any reliable evaluation of climate sensitivity can be measured empirically. The IPCC's presentation of its principal conclusions as though they were near-certain is accordingly unjustifiable. We cannot even measure mean global surface temperature anomalies to within a factor of 2; and the IPCC's reliance upon mean global temperatures, even if they could be correctly evaluated, itself introduces substantial errors in its evaluation of climate sensitivity.

The IPCC overstates the radiative forcing caused by increased CO2 concentration at least threefold because the models upon which it relies have been programmed fundamentally to misunderstand the difference between tropical and extra-tropical climates, and to apply global averages that lead to error.

The IPCC overstates the value of the base climate sensitivity parameter for a similar reason. Indeed, its methodology would in effect repeal the fundamental equation of radiative transfer (Eqn. 18), yielding the impossible result that at every level of the atmosphere ever-smaller forcings would induce ever-greater temperature increases, even in the absence of any temperature feedbacks.

The IPCC overstates temperature feedbacks to such an extent that the sum of the high-end values that it has now, for the first time, quantified would cross the instability threshold in the Bode feedback equation and induce a runaway greenhouse effect that has not occurred even in geological times despite CO2 concentrations almost 20 times today's, and temperatures up to 7 ºC higher than today's.

The Bode equation, furthermore, is of questionable utility because it was not designed to model feedbacks in non-linear objects such as the climate. The IPCC's quantification of temperature feedbacks is, accordingly, inherently unreliable. It may even be that, as Lindzen (2001) and Spencer (2007) have argued, feedbacks are net-negative, though a more cautious assumption has been made in this paper.

It is of no little significance that the IPCC's value for the coefficient in the CO2 forcing equation depends on only one paper in the literature; that its values for the feedbacks that it believes account for two-thirds of humankind's effect on global temperatures are likewise taken from only one paper; and that its implicit value of the crucial parameter κ depends upon only two papers, one of which had been written by a lead author of the chapter in question, and neither of which provides any theoretical or empirical justification for a value as high as that which the IPCC adopted.

The IPCC has not drawn on thousands of published, peer-reviewed papers to support its central estimates for the variables from which climate sensitivity is calculated, but on a handful.

On this brief analysis, it seems that no great reliance can be placed upon the IPCC's central estimates of climate sensitivity, still less on its high-end estimates. The IPCC's assessments, in their current state, cannot be said to be "policy-relevant". They provide no justification for taking the very costly and drastic actions advocated in some circles to mitigate "global warming", which Eqn. (30) suggests will be small (<1 °C at CO2 doubling), harmless, and beneficial.


Even if temperature had risen above natural variability, the recent solar Grand Maximum may have been chiefly responsible. Even if the sun were not chiefly to blame for the past half-century's warming, the IPCC has not demonstrated that, since CO2 occupies only one-ten-thousandth part more of the atmosphere that it did in 1750, it has contributed more than a small fraction of the warming. Even if carbon dioxide were chiefly responsible for the warming that ceased in 1998 and may not resume until 2015, the distinctive, projected fingerprint of anthropogenic "greenhouse-gas" warming is entirely absent from the observed record. Even if the fingerprint were present, computer models are long proven to be inherently incapable of providing projections of the future state of the climate that are sound enough for policymaking. Even if per impossibile the models could ever become reliable, the present paper demonstrates that it is not at all likely that the world will warm as much as the IPCC imagines. Even if the world were to warm that much, the overwhelming majority of the scientific, peer-reviewed literature does not predict that catastrophe would ensue. Even if catastrophe might ensue, even the most drastic proposals to mitigate future climate change by reducing emissions of carbon dioxide would make very little difference to the climate. Even if mitigation were likely to be effective, it would do more harm than good: already millions face starvation as the dash for biofuels takes agricultural land out of essential food production: a warning that taking precautions, "just in case", can do untold harm unless there is a sound, scientific basis for them. Finally, even if mitigation might do more good than harm, adaptation as (and if) necessary would be far more cost-effective and less likely to be harmful.

In short, we must get the science right, or we shall get the policy wrong.

The Winner of the Google Doodle contest

Who can complain about a politically correct drawing?    Well, I can.

First of all, it seems derivative of the bumper sticker that I had on my old car.  

Second, it feels like I am being preached to.  Condescended to.  Like it is telling me that I don't accept people different than me, and that I need to be more accepting, and they are going to tell me who I need to be accepting of.  

In the picture, you have the Muslim hugging the Jew.  Nice idea.  Possible, but not likely.  I wish that it could be true.   The purpose of the bumper sticker on my car was not to say that we should all be friends, which in today's world might not be realistic, but to say that we should live in peace and not kill each other.

On a one on one basis, I can be friends with just about anybody.  But from my perspective, there are groups who would like nothing better than to kill us all, and I am in no hurry to cozy up to these people.

Not a bad finish.

I lost to two higher rated players, including a master, but I beat higher rated SpeedyChess11 in a wild last round game.  

Earlier in the tournament I blundered against two lower rated players, but came back to win both games.  I hadn't done much tactics so far this week, so I needed to get warmed up.

Average Household Income.

If we compare average household income between Indiana and Utah, Indiana is below the national average and Utah is above it.  There is a big difference between the two.   However, if we look at income per capita, Utah is barely below Indiana.  This implies that the average family size is bigger in Utah, which I am sure that it is.

Trump a liar?

Norm, from Utah, said I look foolish in my Trump support because of the constant stream of lies from Trump.   My response to this was ...

"The political sphere has on both has sides different opinions, different interpretations, different spin, and often different misconceptions. Obama said many things I disagreed with, and many things I thought were either spin or inaccurate, but I didn't go around calling him a liar, because I just thought that he had a different opinion than I did. (I actually thought that Obama was a nice, intelligent man, whom I disagreed with.) Republicans view Democrats as misguided, but Democrats either view, or try to portray Republicans as EVIL. That is because Democrats engage in a policy of personal destruction. (I think that this is because it is hard to rationalize excessive government.) Many Republicans still harbor a grudge over the way Robert Bork and Clarence Thomas were treated. What I am seeing now is a daily relentless attack on Trump trying make everything he says or does or anyone associated with him a national crisis. You have tried to claim the moral high ground by saying that you have the better facts, but even if true, which I am not sure about, much of it seems to me like nitpicking given all the crap that goes on in Washington, and it doesn't make your political philosophy better. I think that we are in better hands under Trump, although I say that with the caveat that I think that Trump has inherited a dangerous world and a country way too deep in debt, so I can't guarantee that things are going to be all roses and sunshine. Best wishes, John Coffey"

The facts matter. Trump is proposing policy based on a lie namely that murder rates are at their highest level in 45 years, I hear you saying that's okay because he's picked on. You don't even acknowledge that he misspoke and still hasn't corrected the record. I've noticed that you never call him out on his lies.

"So Trump got one fact wrong. This is the first I have heard about it. But almost everybody has called him out on it, so I assume that he is aware of it. 'One possibility is Trump, back in October, was trying to say that murder in 2015 saw its highest increase in 45 years, which he also said at the second presidential debate. As PolitiFact found, this is mostly accurate: The number of murders rose by 10.8 percent from 2014 to 2015, the highest since an 11.1 percent spike from 1970 to 1971.' Honest I think that he misspoke, as many politicians on both sides have done recently, but to call him a liar, a serial liar no less, is your spin, not mine. I wouldn't have done the same thing to Obama. It is not my nature to do so, but I might be a little too trusting. Best wishes, John"

ACLU 1 | Trump 0

In response to:

ACLU 1 | Trump 0

​I wrote:

I don't want to stir the pot more than I already have, but I feel compelled to say something: American people: 0. This reminds me about the pre-911 debate about racial profiling. That pretty much went out the window after 9-11. Do we need another 9-11 to make people worried about terrorism again? I say NEVER FORGET. What happens when somebody sets off a nuke on American soil? It will make this whole debate look pretty silly. Every September 11th I watch this video: (I'll shut up now. People are entitiled to their opinion. I understand people's desire to be compassionate and I completely sympathize. I just think that the world is an extremely dangerious place right now.)
