Comment on Policy, rhetoric and public bewilderment by Chief Hydrologist

The webster imagines that ocean heat content can be calcalred based on diffusion from the atmosphere to the oceans at a constant rate of ‘effective diffusion’. In reality – the oceans are heated by the sun and ‘effective diffusion’ is physically unealistic.

He uses power rules to ‘model’ an astonishing range of phenomenon – from economics to ecology – without knowing anything about any of them. But the fundamental rule of modelling applies – you need to understand the system before a plausible model can be formulated.

webnutcolonoscope tends to test the limits of implausibility.

That article you linked to about runaway Triassic warming has been thoroughly debunked in WUWT. Nice try though.

You have been wrong about S&T across several threads: <blockquote>S&T are not actually predicting warmer</blockquote> Here is the evidence from S&T09: <blockquote>If the role of internal variability in the climate system is as large as this analysis would seem to suggest, <b>warming over the 21st century may well be larger than that predicted by the current generation of models</b>, given the propensity of those models to underestimate climate internal variability [Kravtsov and Spannagle 2008].</blockquote> You are mistaken. Much of your argument collapses as a result. Whether you admit this or not, it is true.

Conspiracy. A number of the Climategate emails indicated as much.

Self delusion / confirmation bias for the most part.

The ocean heat content has increased and the global land temperature, especially northern continents have warmed during this period. These both have a likely effect on the Arctic sea-ice decline. You may think nothing has happened in 17 years, but this would mean you were asleep/blind while these things were happening.

Yeah. But (late-summer) Arctic sea ice isn’t cancer.

In fact, it’s irrelevant (even to the polar bears).

Remember when it was called “global warming”? And we were told that the warming would be greatest in the polar regions. Ergo, the number of extreme cold events should be reduced. You “realists” can’t have your cake and eat it too!

“So there is a conspiracy amongst the keepers of the temperature records to exaggerate warming?”

Only a Warmer Tribal Troll like yourself pretends the idea hasn’t crossed your mind.

Jim D.,

The refusal by some to accept the increasingly obvious fact that ocean heat content has indeed been rising quite consistently over not just the past 10 or 15 or 20 years, but the past 50 years will prove to be short-sighted for many. This additional energy in the oceans has all sorts of implications for not just the Arctic, but general climate and weather over the short and long term. The wise are studying those implications and others are in denial. Such has been the way of human history for thousands of years.

‘CNGC’ a new label, much more civilised than ‘deniers’. I will wear it with pride.

Yes, it is called taking all the facts into account. Skeptics appear somewhat blind to inconvenient truths, and don’t even discuss them hoping they will go away if nobody takes notice.

Nice. Now we just need to get it printed onto a Christmas card and get it sent out to a number of the ‘team’ and their assistant priests.

An example of “an argument from ignorance”:

Natural variability alone, on any time scale, is not enough to account for the changes [in Arctic sea ice extent since 1979].

But there was apparently a similar change in Arctic sea ice extent from ~1920 to ~1940, when there was hardly any AGW, yet the Arctic warming was quite similar to the current warming there (a period known as the “early 20thC Arctic warming”, or EAW). (Polyakov 2005, Chylek 2006, Berearts 2009 – see my post #268410 above)

Better than an “argument from ignorance”</em ("we can only explain it if w assume…") would be an “argument from evidence”.

But first you have to figure out what caused the EAW.

Glad you approve of the moniker. If the shoe fits…

But you said:

“Since the effects of co2 are logarithmic and the postulated feedbacks in the models have yet to manifest themselves…”

_____
Are you certain the feedbacks have yet to manifest themselves? Global atmospheric water vapor levels have been increasing and sea ice in the Arctic has declined even faster than the models forecast just a few years ago. On what do you base the supposition that feedbacks have yet to manifest themselves?

“In a sense it might be most accurate to say that humans have caused about 200% of the increase, while nature has reduced that to what we can measure in the atmosphere.”

I was going to mention that, but I thought I get some screaming, foul.
But since you said it, I will say some think it’s more than 100% of the global CO2 increase is caused by human activity.

One ppm is equal to *around* 8 billion tonnes of CO2 in the atmosphere.
If you assume that only fossil fuel and cement making causes around 32 billion tonnes of “human emissions”, then 32 is 4 ppm. And we having around 2 ppm yearly increase- hence the idea of 200%.

The other thing is that nature is feared to be having a reduced ability to absorbed “the large amounts human emissions” in the future. Despite the evidence, contrary.

And both are a simplistic understandings.
And informed by the myth of Man vs Nature. Which sort of goes like, Humans are this big terrible force and Nature is some timid and placid creature. And Nature is Good and Man is Evil. Etc. Very old religion- with a fair number of followers.

I agree, with Hitchhiker Guide view- humans are mostly harmless. And preferable if Humans were a bit more dangerous, rather than remaining somewhat pathetic. The Universe is big- really big.

“It seems very likely that there are no significant other sources for the increase than the human influence. Thus the two valid numbers are 100% and about 200% and the choice between them depends on the interpretation (not on uncertainty on what’s going on). There’s natural variability, but that averages out over periods of a few years. That variability is what Salby has observed.”

It would appear that the apparent sudden increase in global CO2 starting in the 20th Century is human caused.
I think Salby has offered a compelling case which might provide additional answers.
And other than broad indications I am not very confident in the proxy record of global CO2. Or not willing to have the record of CO2 measurement at Mauna Loa being considered as equal to these proxy measurements.
I think that if people are confident that CO2 levels remain nearly constant for thousands of years, then I would say they are over confident.
And would say that this kind of mistake has been made in the past.

As general observation, there are too many elephants in the room.
So generally I am willing to accept the idea that human may be adding more than 100% of the increase in CO2 or less than 4% of added CO2, but tend to think that for next decade or so we will continue to have increase global about 2 ppm per year- regardless of which extreme is correct.
I do, think it would prudent to conduct more experiments regarding Ocean fertilization to determine if this could a be significant means of altering global CO2 [also want to know effects upon ocean food production].
Such knowledge could serve our survival toolkit, if there is a need to reduce CO2 levels [and it's possible factors other than human activity could significantly increase global CO2 level].
But at this point in time, if we had the option [with zero costs] which would reduce global CO2 levels, I would not consider it a good idea to do so.
This because our current levels of CO2 seem to be having more benefit as compared to if they were at lower levels- in terms of vegetation and the growing of crops.

Someone broke the thread again.

Okay CH, I will say it for you:

You were completely wrong about what S&T says about the implications for C21st warming. This statement is incorrect and misleading:

S&T are not actually predicting warmer

Wrong and misleading.

You misrepresented S&T over the course of several threads in the promotion of a specious argument about the likely frequency, duration and significance of cooling episodes during this century.

The very scientists you quote ad nauseam do not agree with your conclusions. And although I showed you the relevant quote from S&T more times that I can count, you were utterly incapable of reading/understanding the words in front of your nose. You have completely discredited yourself. All you had to do was *listen*, but no.

What is actually worse is that despite being exposed as being entirely wrong, you haven’t got the decency to admit it and accept that this largely demolishes your position. You literally *cannot* say ‘sorry, I was wrong’. It’s *pitiful*.

Which brings us to the appropriate and final absurdity. Here’s you, being your usual unpleasant blog crank self earlier:

‘The ability of space cadets to ignore evidence is constantly astonishing.’

You have proved yourself to be a perfect space cadet and more besides, haven’t you? Nice work, CH. BBD – Booger Brain Dead

Passive aggressive when not actually being aggressive and abusive. The cooling episode is fairly obvious – http://earthobservatory.nasa.gov/IOTD/view.php?id=8703 – and should last another decade or three. The Tsonis papers are about climate shifts. Chaotic bifurcations in the instrument record.

For those unaware – Anastasios Tsonis, of the Atmospheric Sciences Group at University of Wisconsin, Milwaukee, and colleagues used a mathematical network approach to analyse abrupt climate change on decadal timescales. Ocean and atmospheric indices – in this case the El Niño Southern Oscillation, the Pacific Decadal Oscillation, the North Atlantic Oscillation and the North Pacific Oscillation – can be thought of as chaotic oscillators that capture the major modes of climate variability. Tsonis and colleagues calculated the ‘distance’ between the indices. It was found that they would synchronise at certain times and then shift into a new state.

It is no coincidence that shifts in ocean and atmospheric indices occur at the same time as changes in the trajectory of global surface temperature. Our ‘interest is to understand – first the natural variability of climate – and then take it from there. So we were very excited when we realized a lot of changes in the past century from warmer to cooler and then back to warmer were all natural,’ Tsonis said.

Four multi-decadal climate shifts were identified in the last century coinciding with changes in the surface temperature trajectory. Warming from 1909 to the mid 1940’s, cooling to the late 1970’s, warming to 1998 and declining since. The shifts are punctuated by extreme El Niño Southern Oscillation events. Fluctuations between La Niña and El Niño peak at these times and climate then settles into a damped oscillation. Until the next critical climate threshold – due perhaps in a decade or two if the recent past is any indication. I am as I keep saying a climate catastrophist (in the sense of Rene Thom) and refuse to predict past the current cool state. These states are inherently unpredictable.

Swanson and Tsonis stated in their 2009 paper that these shifts imply sensitivity and that warming may well be greater than predicted in this century. It may well be cooler. There is no theoretical justification that these spontaneous reorganisations of the climate system – and of cloud cover especially – will be to cool or warm. S&T09 did not predict warming because as they are well aware – unlike BBD – this mechanism they are talking about (A new dynamical mechanism for major climate shifts) is in principle deterministic but practically incalculable.

So my calm reply prompted this tirade of millennialist cult of AGW groupthink space cadet outrage. Simply because dynamical complexity leads to uncertainty. I keep suggesting that he Google the relevant terms and educate himself. But perhaps there are people who are unable to grasp this idea. The ill-informed arguments of the webster with Tomas come to mind.

BBD is obnoxiously stupid and opinionated and has such a facile approach. This is definitely a pattern with the space cadets. As an unpleasant blog crank – the ability to ignore anomalous information is great and the toleration of dissention from the groupthink memes before descending into absurd hand waving tirades is negligible.

As for saying it for me – thanks but no thanks

Forgot to mention that clouds for example involve all those little “second order effects” Webby seems to wants to ignore. That’s just one example of why the models are relied on so much in this field, smart people realize the effects are very impotant. Webby, where does this leave you? However, this reliance doesn’t mean the models are fit for their intended purpose.

Down down down is fine by me. That’ll help us extract that oil and gas.
