Solutionizing And The Near-Death Of Watts Up With That

19

Recently, there’s been plenty of gnawing of climateblogging teeth for the silliest of reason. Simply, Willis “Rooster Cogburn” Eschenbach took umbrage of Tallbloke and posted at WUWT what was later revealed an act in some kind of psychodrama (with plenty of censored comments – my own comment to the latter, including a “GET A LIFE” exhortation, hasn’t has finally seen the light of day as yet).

Tallbloke has responded here and here. The end result has been that WUWT has apparently transmogrified into Climate Progress, after celebrating its 100M hit. Not sure how long I’ll hang around it, unless things change.

And the topic that has caused so much heating? If there is any gravitational explanation for the “greenhouse effect”. Cue millions of words written for nothing.

The actual problem as I see it is called “solutionizing”.

People tackle the problem of why bumblebees fly, some ideas are thrown around, those ideas are incomplete, so people come to the conclusion that since there is no solution to the problem, bumblebees don’t fly.

In the meanwhile, bumblebees fly. Back to square one.

In management circles, this is all pointed out as a fundamental error…the fact that you don’t have a solution doesn’t mean the problem is impossible to solve. It simply means you should concentrate on analysing the problem and in collecting more data, rather than immediately try to identify a solution.

For those harder in understanding, the observation is that independently from the composition of the atmosphere and the presence of a solid surface underneath it, every planetary atmosphere in the solar system has a “troposphere”, defined as the part where downward lapse rates are positive, i.e. temperatures increase as the distance from the top of the troposphere increase.

The same thing applies to any self-standing gas cloud anywhere in the universe. There is always a surface “below” which temperatures increase with pressure. Otherwise stars won’t ever ignite.

Now if this is because of whatever Hans has said, or N&Z, or it’s Tooth Fairies, that is not a question that will ever be answered in blogs (and especially, in their comment sections). But anybody stating that what the whole cosmos is alight by is “impossible”, they do have a problem telling truth from fantasy.

Do Climate Forcings Exist? Map And Territory In Climate Science

2

Some interesting ideas that are surfacing at Judith Curry’s “Cloud wars” blog post, leading to the conclusion that there might as well be no such a thing as a “pure” climate forcing.

A “pure” climate forcing (i.e. one that occurs only as a forcing to the climate system, not also as a feedback) is of course an independent input to the system. IOW it is an independent variable that will provide its “push” in a specific direction whatever the value of all other variables.

It sounds obvious (maybe not to the average Climate Believer) that a great deal of so-called forcings aren’t: clouds of course (both a forcing and a feedback, perhaps on different timescales); but also CO2 emissions (as noted by commenter Eric Ollivet), water vapor, and pretty much anything that happens in the atmosphere.

One is left with the influence of other planets, of volcanoes, and of course of the Sun. But are those true and “pure” forcings, really?

For example, who’s going to demonstrate that the atmosphere will respond predictably and progressively if the Sun input to it varies, and everything else remains equal? For all we know, the Sun could be a positive forcing up to a point, then negative, then positive again, or simply positive but by different amounts following a complex multi-step function that moves up and down, all according to the atmosphere’s initial status.

Actually, we can be pretty sure of all that complication, thanks to the Mpemba effect (and the Leidenfrost effect).

Every reduction and simplification seems poised to destroy our ability to understand the climate itself. We might be ending up trying to apply statistics and/or computer models simply to distract us from the underlying truth: perhaps, in climate science, the only good map IS the territory. And the only hope to understand the climate, is by considering it whole.

How to Be Right About the Climate: Always!

(originally published on Nov 17. 2007. The Italian version is here.)

Vincenzo Ferrara, the scientist advising the Italian Environment Minister up to April 2008 on Climate Changes, explains how to become a famous Climatologist in a 1982 article (on the ”Rivista di Meteorologia Aeronautica”, Vol XLII n. 1, Jan-Mar 1982).

The following is an abridged translation:

If you are a climatologist and you want to survive as a climatologist, perhaps even increasing your reputation, all you have to do is provide the exact diagnosis and prognosis that people expect.

To the question “Is the climate changing?“, by all means, never, ever reply “No, everything’s normal“, or “It’s just fakery pumped up by newspapers and on television“: because people would unanimously conclude that you understand nothing about metereology, and nothing about climate.

It would be the end of your career.

The only sensible answer is: “Of course it is changing! It’s a well-known fact, scientifically confirmed and one that none cannot argue against“. You can then launch yourself in forecasting for the next hundred years a climate identical to the current one, amplifying the latest phenomena to extreme consequences.

If it is cold you’ll therefore predict “ice ages“, if it’s warm a “torrid period“, and if there are signs of strong variability “short-term climatic extremes” and more-or-less the same climate in the long term.

You may be wondering, how can a serious climatologist provide impossible, mutually-excluding forecasts without looking silly? Fear not: science will provide all the support needed.

Because climatology has already thought of everything and will supply the right solution in every circumstance, even in the most hopeless cases.

So if it is cold, here’s what you will have to say: “The climate is changing and we are approaching an Ice Age.

This fact has already been scientifically assessed because since 1940, the average temperature of the northern hemisphere has diminished by approximately 0,4°C, probably because of a decrease in atmospheric transparency due to air pollution.

The cooling of the air causes an increase in the extension of glaciers and of snow fields, furthering lowering temperatures with their highly reflecting (high albedo) surfaces. Glaciers therefore increase even more, in a positive feedback that will bring us to a new Ice Age in a hundred years or even less“.

What if it is warm? Then the discourse becomes: “The climate is changing and we are approaching a Torrid Age.

This fact has already been scientifically assessed because since 1850 the carbon dioxide content in the atmosphere has progressively increased and just in the last twenty years has gone from 315 to 334 parts for million. That means that in 2020 the accumulation of carbon dioxide will have more than doubled, taking into account the continuously increasing energy demands and consumption of fossil fuels.

The increase of carbon dioxide reduces the Earth’s long-wave emissions to space (greenhouse effect) so within half a century the average air temperature will increase by approximately 2 or 3°C; the polar ice will dissolve and a sizeable sea level increase will submerge several coastal cities“.

A climatology joke is in order…
