Assisting the Minister fight the climate

Setting New Zealand’s post-2020 climate change target

Submission to MfE by Climate Conversation Group

Sent today, 20 May 2015

It is a great irony that you should call this a “climate change” target, for the science tells us New Zealand doesn’t change the climate. It is a fact that, were we to reduce our emissions even to zero, thus achieving the greatest possible reduction, though destroying our entire productive capacity, there would be no resulting change in the average global surface temperature.

Global human emissions in 2013 were 36 gigatonnes; NZ emissions in 2013 were 0.0542 gigatonnes—about 0.15% of global emissions. As for the amount of warming expected from those emissions in a year; it is vanishingly small: in removing them all, our sacrifice would be undetectable.

So you seek a climate change target that cannot change the climate.

First point

That’s the first point of our submission: the science tells us that our best efforts in reducing emissions will not change the climate. Throttling back would be a waste of time and money because we don’t affect the climate even at full throttle. The Ministry for the Environment claims our reductions are necessary to inspire other nations, but we don’t know why they would listen to us: we say please use our money for anything useful.

Second point

Our second point is that there’s been no exceptional warming detected so far, either in the atmosphere or the oceans. Nor has the cryosphere shown exceptional diminution anywhere. The much-cited record reductions in Arctic sea ice recently quickly recovered to normal levels. The record lows were caused not by high temperatures but by strong winds moving the ice into the Atlantic where it melted.

The reductions were unusual, but not unprecedented, because they also occurred in the early 20th century, when our emissions could not have been the cause. The Antarctic sea ice, far from diminishing, continues its steady increase of the last 30 years.

Third point

The third point is that the sole support for predictions of dangerous warming are climate models—but they are faulty. We know this because observations over the last 20 years or so show the observed temperatures becoming increasingly cooler than the model predictions. This is easily verified. Let me repeat: the climate models are proved to be wrong.

Fourth point

Fourthly, a vital link in the supposed chain of causation from our emissions, to atmospheric warming and thus to oceanic warming is missing. To wit: the air cannot significantly heat the sea. We have been researching this for years but have not found a paper that describes this alleged phenomenon. This is no trivial omission, for if our emissions into the atmosphere cannot heat the sea then we can scarcely be held responsible for a sea level rise they did not cause. We can provide more information if the minister requires it and we implore the minister vigorously to confirm this point. This one scientific fact alone has the power to invalidate the need for us to act, for the other ramifications of the entirely mild atmospheric warming to be expected from our emissions are highly likely to be wholly beneficial.

Fifth point

Finally and fifthly, the Intergovernmental Panel on Climate Change (IPCC), which has been agitating for a climate treaty for 30 years, has engaged in deception and ruinous distortion of the science—such as brazenly claiming hurricanes had increased under the influence of global warming when the world’s leading hurricane expert had just told it they had not increased—therefore many people no longer trust it.

Conclusion

In conclusion, since there’s no reason to believe our emissions cause dangerous warming now or in the future, as the emissions even of the entire human race have caused no detectable warming for about 20 years, and since there is no evidence of unprecedented warming in the last several hundred years, and since the only sign of future dangerous warming is faulty climate models, and since the UN body exhorting us to act has not earned our trust, we therefore implore the minister to delay his decision on setting New Zealand’s post-2020 climate change target until the facts we outline above can be verified, or at least until the Paris conference of the parties is over and we can see whether anything has happened.

Yours faithfully,
Richard Treadgold,

Good effort, well said,

However, with Dr Wratt now embedded in the government, I think we can expect some “homogeneous thought” on the climate issue, and facts will be deemed irrelevant, especially when coming from the pens and mouths of mere serfs.

Thanks Richard. I do get a bit down with all the “doublethink” that is prevalent in our society these days, of which the climate agenda is one small part.

There are a great number of people who do see sense and who do not shout or tweet or attend “climate target” meetings. (Some of these people have been dubbed “Shy Tories”, but it would be imprudent to label all shy people as Tories, of course)

There does seem an increasing disconnect between our “elite” and the proletariat. One snippet for you – all the candidates for the UK Labour Leadership are Oxford or Cambridge graduates. Milliband is a graduate of Corpus Christi Oxford, and Cameron from Balliol Oxford.

None of them has a science or technical degree either.

Richard, The points you have made (above) are excellent and I really do hope that Dr Wratt takes them on board. I admire the work you do and am awed by the time you must expend in research, writing, proofing and presenting it all. I know, as one who loves writing, that is it not a rapid process! Richard and Andy, I too get really annoyed at the nonsense that is thrust at us by the the MSM and associated ignoramii, but the facts as we understand them are appearing in public view more often now than in the past. My observations of politicians in the UK: None of them, that I could discover, had ever had what may be defined as an actual job before strapping on their training wheels and campaigning to become a Local Body Politican, which seemed (to me) to be an evil strain of politics – why on earth would it matter if a local body was run by any particular brand of politician, but it appears to matter greatly in the UK. I prefer our system in NZ, where national politics are largely divorced from local bodies.… Read more »

PPE is the Oxford degree “Politics, Philosophy and Economics”.

Generally regarded as a bit of a soft touch degree

BTW, I noticed that Roger Helmer MEP (UKIP) is a Maths graduate from Churchill College Cambridge, which(cough) happens to be true for me too.

I also note that Christopher Monkton is a classics graduate from Churchill. Since Helmer is an outspoken critic of wind energy and generally on top of climate change BS, I think we can safely conclude Churchill is a bastion of “denial”

One would have thought this was self evident but very helpful I’m sure for those actually interested in the basis of the UN’s crisis. Like our government should be for example.

Tim Groser and his entourage of policy wonks (mostly Trade & Industry, not heat experts, devoid of any ability to critique the IPCC science case, as is MfE) should not be going anywhere near the Paris COP (and why Lima, Durban, Cancun, Bali etc?) until the models are reconciled with reality.

But then, when that’s done (if ever), the issue defeats itself.

[Stuff] – Obama repeated arguments he cites often to promote his climate change effort, including a litany of grim facts and figures about rising temperatures, swelling seas and vanishing sea ice, dismissing skeptics of the phenomenon or those who refuse to act on it as guilty of “negligence” and “dereliction of duty.”

>”or flux detected (Chap 3)” [IPCC AR5]

Even if an air-sea DLR flux was detected that could be attributed to human cause, say 1000 W.m-2, there can be no heating effect on water – the radiation-matter interaction physics precludes it.

In reality, CO2 only contributes 6 W.m-2 (US Standard Atmosphere 1976) of actual in-situ DLR fluxes (say 400 W.m-2 in the tropics), and the posited CO2 forcing (assuming valid) is only around 0.3 W.m-2/decade right now when human CO2 emissions are the highest in the industrial era. So now it’s 7.2 W.m-2 (whoop-de-doo).

This is a non-issue.

‘Jeb Bush rails against ‘intellectual arrogance’ in climate change debate’

By Ashley Killough, CNN May 21, 2015

Jeb Bush hit back against President Obama’s claim that climate change runs an immediate risk, saying Wednesday that while it shouldn’t be ignored, it’s still not “the highest priority.”

As he has before, Bush acknowledged “the climate is changing” but stressed that it’s unknown why. “I don’t think the science is clear of what percentage is man-made and what percentage is natural. It’s convoluted,” he said at a house party in Bedford, New Hampshire.

“For the people to say the science is decided on this is really arrogant, to be honest with you,” he continued. “It’s this intellectual arrogance that now you can’t have a conversation about it, even. The climate is changing. We need to adapt to that reality.”

Ah yes, the “precautionary principle”. Foisted upon us by “post-modern” science (basically, make it up as you go along). And only necessary by that paradigm. Not so much by the conventional scientific method.

Congratulations Richard on a nice clear position statement.

“Jeb Bush hit back against President Obama’s claim that climate change runs an immediate risk, saying Wednesday that while it shouldn’t be ignored, it’s still not “the highest priority.”

It seems to me that the right and increasingly the centre-right are buying the arguments supported here that AGW is basically a fraud. The proponents of the left liberal green wing – who tend to be much louder – are getting more and more desparate in maintaining their increasing untentable position.

The left’s investment in their postion is massive. Jobs, income, belief structures and the (potentially lost) opportunity to change the world order. They will not give up all that lightly.

Fortunately they mainly listen to their own group think rather than find out what the silent majority thinks and eventually that will bite them where it hurts,

The truth will out.

First point should also compare per capita emissions.
The chart in Point 3 should be referenced and it should be sourced from a peer-reviewed paper.
Point 4 will probably cause fits of laughter in the MfE smoko room. There is significant interchange of heat between the atmosphere and ocean. To deny otherwise is putting yourself in the crank category.

That would be Dr Vera Power. Manager, Science and Evaluation.

What makes Dr Power a radiative heating expert Simon?

And the search for Dr Power is, as from the post:

“To wit: the air cannot significantly heat the sea. We have been researching this for years but have not found a paper that describes this alleged phenomenon.”

There’s nothing (no paper citation) in AR5 Simon. Perhaps given your knowledge of the MfE smoko room you might be able to persuade Dr Power to produce what the IPCC cannot.

Good luck with that BTW.

‘NASA’s Dr. Gavin Schmidt goes into hiding from seven very inconvenient climate questions’
Guest essay by Dr. Roger Pielke Sr.

5. There is considerable debate as to where heat has been going in recent years since the temperature increases at the surface and troposphere have flattened. On example of this discussion is in the post
http://judithcurry.com/2014/08/21/cause-of-hiatus-found-deep-in-the-atlantic-ocean/

Q: Since it is claimed that a large fraction of the heat from human input of CO2 and other greenhouse gases has been going into the deeper ocean over the last 10-15 years (as an attempt to explain the “hiatus”), why is the global average surface temperature trend still used as the primary metric to diagnose global warming?

On the other hand, here’s the seminal paper of an in-situ study clearly showing that the sun, not CO2, heats the ocean in the tropics:

‘Cool-skin and warm-layer effects on sea surface temperature’
Fairall et al (1996)

How can CO2 possibly top that except in warmists dreams?

The IPCC set the stage and airborne CO2 and air temperature are their chosen metrics. This despite the fact that there is 40,000 times as much CO2 in the oceans and the heat content of the oceans compared to the atmosphere is likely a similar ratio.

If in fact the AGW is real and the missing heat is going into the oceans, the ability of the oceans to keep doing that is, to all intense and purposes, infinite.

Richard C (NZ)

I like your “infinite” reasoning Hemi but I’d like to expand a bit on this line: >”If in fact the AGW is real and the missing heat is going into the oceans” This is highly problematic conjecture on the part of the IPCC (their “air-sea flux” speculation AR5 Chapter 11). The rationale for it is their Radiative Forcing methodology (RF). Their process is: TOA CO2 forcing restricts OLR (it hasn’t) therefore there must be planetary heat buildup somewhere. The posited heat buildup is not evident in the atmosphere (the missing heat, most critically the upper tropical troposphere where the greater part was originally supposed to manifest) therefore the heat must be going into the ocean, irrespective of AO interface physics and observations. So there is no physical thermodynamic explanation for the IPCC’s A to O heat transfer (as would normally be calculated), instead their RF methodology “imputes” heat to the ocean bypassing the AO interface heat budget and physics, like some sort of tele-connection. They go looking for evidence of the transfer (AR5 Chapter 3) but don’t find any (natch). No professional heat specialists e.g. engineers, technologists, chemical, mechanical, process etc would survive… Read more »

[IPCC] – “detection of a change in air–sea fluxes responsible for the long-term ocean warming remains beyond the ability of currently available surface flux data sets”

They might have considered the obvious long-term candidate for responsibility but no, this is the IPCC.

For example,

‘A new approach to long-term reconstruction of the solar irradiance leads to large historical solar forcing’
A. I. Shapiro1, W. Schmutz1, E. Rozanov1,2, M. Schoell1,3, M. Haberreiter1, A. V. Shapiro1,2, and S. Nyeki1
(2011)

4. Results and Discussion

“The difference between the current and reconstructed TSI during the Maunder minimum is about 6 ± 3 W/m2 (equivalent to a solar forcing of FP−M∼ 1.0±0.5W/m2) which is substantially larger than recent
estimates (see Sect. 1).”

http://arxiv.org/pdf/1102.4763.pdf

Thing is, solar energy (DSR), does real work e.g. heats the ocean. DLR doesn’t.

“In other words, an anthropogenic air-sea flux forcing, even if valid in concept (it’s not), and even if it could be isolated (it can’t), is negligible.”

…and therefore “the ability of the oceans to keep doing that (if indeed it was) is, to all intense and purposes, infinite”

I just think that this is an easier sell than saying there is no known mechanism.

Except it’s not selling truth Hemi. You’re leaving the door wide open for misrepresentation (untruth) i.e. those who conflate natural ocean heat accumulation with spurious anthropogenic cause, albeit negligible if accepted because it’s “easier”.

Case in point, SkepticalScience:

[see graph] “More than 90% of global warming heat goes into warming the oceans” [hotlink]

http://www.skepticalscience.com/global-warming-stopped-in-1998.htm

The hotlink leads to this page:

Global Warming Components – Where is global warming going?

http://www.skepticalscience.com/graphics.php?g=12

Ocean 93.4%.

But that’s not Anthropogenic Global Warming which can only, truthfully, be attributed to the troposphere if the hypothesis is verified (it isn’t)..

Then in the sidebar, SkS have their “Hiroshima atomic bombs of heat” widget i.e. they’re spinning natural phenomena to the political moon.

In the internet age where information travels at the speed of light, a lie is many times around the world before truth gets its boots on.

The truth. My version of truth is that CO2 is an significant contributor to Global Warming and that our ability to accurately predict future climate is about one week.

Just googled this:
If enough energy was taken from the oceans to heat the air by 2C the sea temperature would drop by 0 .0005C

There are clearly large energy exchanges from evaporation and rainfall and the oceans will buffer our climate quite effectively has they have done for millennia

The Truth. My version of the truth is that CO2 is an insignificant contributor it Global Warming and that the rest of the house of cards is a sham and that we can predict weather for about a week.

However just pulled up this diamond. If enough energy was draw from the ocean to lift the global air temperature by 2C the temperature of the oceans would drop by 0.0005C.

There are clearly big energy exchanges due to evaporation and rainfall and I am comfortable that the sea will buffer the climate for a few generations to come.

Truth is a funny thing.

Ocean surface heating occurs at the boundary through interchange of H2O, CO2, and energy. Ekman transport can then drive that heat down to lower levels. Even if this effect was marginal, the statement that “if our emissions into the atmosphere cannot heat the sea then we can scarcely be held responsible for a sea level rise they did not cause.” is nonsense. Sea level does increase from thermal expansion, but the biggest factor is melting sea ice.
Sea ice volume is a more valid metric than sea ice area, but much more difficult to measure.

>”the sea will buffer the climate for a few generations to come” Debatable timeframe (see below) but not for nothing is the sea termed the planet’s largest heat “sink”. It is an enormous buffer the surface temperate of which varies little more annually than diurnally in extremes. Here’s Environment BOP’s Wave Buoy temperature off Pukehina: http://monitoring.boprc.govt.nz/MonitoredSites/cgi-bin/hydwebserver.cgi/points/details?point=834 16.8 to 20.3 last 12 hrs 14.3 to 23.5 last 12 mths Temperatures were up around 21 but have only just plunged this month i.e. the heat advantage of the buffer is gone for this season. But on a multi-centennial timescale, far longer than the IPCC’s 6 decade 1951 – 2010 anthro attribution period, the oceanic heat accumulated (buffered) between solar Grand Minimum (Maunder/LIA) and Grand Maximum (Modern/MWP) will benefit climate comfort levels for some years (I say about 3 decades 2005 – 2035) But a sobering thought. It is not out of the question that solar levels return to Gleissberg, Dalton or Maunder levels by around late 2030s. The climate scenario commensurate with Maunder levels (LIA) is this, from Wiki: “Freezing of the Golden Horn and the southern section of the Bosphorus took place in 1622.… Read more »

>”Ocean surface heating occurs at the boundary through interchange of H2O, CO2, and energy.” OK, we’ve finally elicited a response from you Simon. I was beginning to think you were nothing more than a hit-and-run fly-by troll but this is an unexpected engagement. You demand “peer-reviewed literature” from us but you don’t provide any yourself to support your opinion above. What I’m getting at is that your statement is devoid of any quantification either by theory or empirical in-situ study. Neither have you provided the conceptual thermodynamic AO interface physics (the “boundary”). But I can help you out with that (unlike you we’re used to producing “peer-reviewed literature” to support our contentions).

Simon, you say: >”…the statement that “if our emissions into the atmosphere cannot heat the sea then we can scarcely be held responsible for a sea level rise they did not cause.” is nonsense. Sea level does increase from thermal expansion, but the biggest factor is melting sea ice.” Apart from the sea ice gaffe (already dealt with by RT), your rebuttal is a non sequitur in respect to what you are attempting to rebut, viz,: “Sea level does increase from thermal expansion” Yes it does but you’re conflating natural cause with anthropogenic supposition. Yes of course the level of water in a confined space will rise if the water is heated but what is the heat source? Obviously (see Fairall et al upthread) the heat source is solar energy. Any variation of it will produce either sea level rise or fall. This is thermodynamic fact – not “nonsense”. And it has already been shown that the IPCC has no evidence of anthropogenic ocean heating (Chapter 3, Chapter 10 linked upthread). Again, fact – not “nonsense”. You CANNOT conflate the two.

>”CO2 may provide a small, unknown amount of energy to the ocean by radiation” The amount has been estimated at 6 W.m-2 in the US Standard Atmosphere 1976. I can dig out a citation if required. CO2 peak emission is at 10 microns wavelength so is towards the longer DLR range of 4 – 16 microns wavelength in the IR-C range (IR-C is 4 – 100 microns). But it’s not “real” effective heating power as is IR-A/B in the shorter wavelength (and far higher energy-per-photon) solar spectrum. And there’s minimal penetration i.e. “tracklength” over which radiative energy is transferred to matter. But CO2 is a minor component of DLR which can be around 400 W.m-2 in the tropics (e.g. Darwin BSRN measurements). And the 0.3 W.m-2/decade CO2 “forcing” is negligible in amongst that even if valid (it’s not). I think Simon is suggesting that CO2 adds to the oceans sensible heat (Hs) when a CO2 molecule at air temperature is absorbed at the sea surface (I.e. an Hs transfer). Problematic when CO2 is only 400ppm and the sea surface is on global average about 3 degrees Celsius warmer than the air above it.… Read more »

>”I don’t know how they calculate the amount of melting from glaciers and ice sheets caused by an anthropogenic contribution to atmospheric temperatures that have not increased for about 20 years”

Keep in mind that an increase is not necessary for melting, just sustained high levels of temperature – like the MWP, or the CWP (Current). It is a normal natural process to be expected (think human settlements uncovered by the melting in the Alps).

But we are in an inter-glacial period characterized by freeze-thaw-freeze-thaw cycles e.g. MWP – LIA – CWP. I’m not at all worried about thaw, it’s the freeze thought that’s gets me.

>”I guess they don’t care if we think we caused all the melting” Exactly. That’s the impression they’d like disseminated. The AR5 SPM has it thus on page 13: D. Understanding the Climate System and its Recent Changes Understanding recent changes in the climate system results from combining observations, studies of feedback processes, and model simulations. Evaluation of the ability of climate models to simulate recent changes requires consideration of the state of all modelled climate system components at the start of the simulation and the natural and anthropogenic forcing used to drive the models. Compared to AR4, more detailed and longer observations and improved climate models now enable the attribution of a human contribution to detected changes in more climate system components. Human influence on the climate system is clear. This is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding of the climate system. {2–14} http://www.ipcc.ch/pdf/assessment-report/ar5/wg1/WG1AR5_SPM_FINAL.pdf First problem being that the models are now no more than junk science (the IPCC alludes to this in Chapter 9, more below from the SPM).

Further to my SPM screed. First note the IPCC’s anthro attribution period (page 15 pdf): D.3 Detection and Attribution of Climate Change • It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together. The best estimate of the human-induced contribution to warming is similar to the observed warming over this period. {10.3} OK, 1951 to 2010 (and note there has been no statistically significant warming this century). Figure SPM.1 (a) on page 4 pdf shows just how weak the IPCC case above is. 1) Only 2 decades of warming within the anthro attribution period (1980s and 1990s). At first glance looks like 0.6 C, but the 1940s (prior to the attribution period) were already higher than the 1970s so the net warming 1940s to 2000s is about 0.45 C, fractionally more than 1900s to 1940s (say 0.42 C). 2) the slope of the warming 1910s to 1940s (4 decades) is the same as the slope of the warming from 1970s to 2000s (4 decades). 3) What exactly,… Read more »

[IPCC] – >”The reduced trend in radiative forcing is primarily due to volcanic eruptions and the timing of the downward phase of the 11-year solar cycle” Good grief. They’re isolating one solar cycle (SC 23) corresponding to only the 2000s “hiatus” (1996 June to 2008 January, see below). Except after 2008 there was the upward phase of SC 24 which has just peaked midway through the second decade 21st century (2010s) and corresponding to the AR5 report date. More importantly, what about the “timing of the downward phase” of SC 22 which ended 1996 June right in the second of only 2 decades exhibiting any warming in their attribution period? They can’t have it only one way. More importantly still, what about planetary thermal lag that displaces temperature from solar activity by whatever estimate from the literature you might chose? Could be 8 – 20 yrs (Abdussamatov), 30 – 40 yrs (Zhou and Feng), or 10 -100 yrs (Trenberth essay). There are others too. List of solar cycles http://en.wikipedia.org/wiki/List_of_solar_cycles Apart from those deficiencies, the major solar problem confronting the IPCC is NOT “the downward phase of the 11-year solar cycle”, it is the… Read more »

Richard T,
Thanks for the kind words. As you now know, a PPE from any university is not something that fills the average voter (ie, me) with enthusiasim, or even confidence in the holder.
The more one looks at the graphical representations of of the climate of the earth over time, the less confidence one has in the notion of Man’s influence upon said climate despite the fears of Simon and his cohort.
To me, the very expensive recipes for avoiding ‘Man changing the climate’ seem rather similar to a poor parish purchasing their priest the very best of non-meat epicurean delights for his non-meat Friday repast: said delights will have a negative effect on the poor parish and an equally negative impact on the health of the priest as epicure.
In short, AGW mitigation appears to effect the poor of the third-world rather more than it should. Which, of course, is ‘on message’ for the most powerful ‘environmental’ groups such as the Club of Rome, Greenpeace, etc., who appear to have a pathological dislike of poor people who also posess dark skins.

Richard T,
Further to my thoughts on PPE, etc, I tend to admire the Australian PM as he actually does some public-spirited ‘blokey’ stuff which involves putting himself at risk in what can be quite hairy situations, i.e. Surf Life Saving and as a bush-based Volunteer Fireman, which allows me to think that PM Abbott’s PPE degree can be forgiven!

Poll today on Whaleoil of views on Climate Change

Almost exclusively a natural process 38%
Humans have an insignificant impact 39%
Humans have a measureable impact 18%
Other 5%

This actually amounts to a poll of (a selection) of national voters, but national voters do represent 50% of the population and nearly all of them vote.
