‘Air Con’ and ‘Totalitaria’ author Ian Wishart debates Green party co-leader Russel Norman on climate change

[Russel Norman’s comments extracted from Green Party climate speech, 1 June 2014]

NORMAN: I’d like to briefly touch on some of the latest climate impacts around the world.
Because I know how easy it is to lose track. The effects of a warming planet can begin, after a while, to seem like a bizarre sci-fi film playing on repeat in the background of daily life.
The sheer scale and cost of what’s occurring is difficult to comprehend. From the tropics to the poles, from the mountains to the sea, from the poorest countries to the richest, climate change is tightening its grip.

The last few years are perhaps best summarised as a series of “is this really happening” moments. Antarctic ice loss being one such moment. We recently learnt that parts of the ice sheet have begun an irreversible slide into the sea. 160 billion tonnes of ice is being lost every year – twice as much as when the Continent was last surveyed. Antarctica is literally shedding ice.

The resulting sea level rise doesn’t bear thinking about.

The impact on coastal communities, of which New Zealand has many, is likely to be catastrophic.

WISHART: Russel, you are trying to induce newspaper, radio and TV journalists to make fools of themselves in the eyes of their educated readers/viewers, because the latter group know the science and they facepalm every time a gullible journalist falls for rhetoric over facts. Why don’t we read the peer reviewed science together. Here’s what climate scientists have discovered about West Antarctic ice melt:[1]

“The record shows that this region has warmed since the late 1950s, at a similar magnitude to that observed in the Antarctic Peninsula and central West Antarctica; however, this warming trend is not unique. More dramatic isotopic warming (and cooling) trends occurred in the mid-nineteenth and eighteenth centuries, suggesting that at present, the effect of anthropogenic climate drivers at this location has not exceeded the natural range of climate variability in the context of the past ~300 years.”

Key phrases? How about “this warming trend is not unique” and the effect of human CO2 emissions has “not exceeded the natural range of climate variability”? Those two points demonstrate to any journalist or objective observer that there is nothing, absolutely nothing, special or unprecedented about Antarctic melt to date.

That finding is backed up by yet another this year, which reports warming cycles in Antarctica like the current one have occurred five times in the past 350 years alone:

“The data suggest that during the past 350 years such events have taken place at least five times.”[2]

What part of ‘irreversible’ do the Greens fail to understand? It has warmed and cooled again at least five times recently, none of which had anything to do with CO2.

Perhaps the Green Party’s ‘science advisors’ have not told you Russel, but I will: the part of Antarctica losing the most glacial ice of all – in fact it is the biggest single contributor to sea level increase in the world – is the Pine Island Glacier. It’s a monster throwing massive amounts of ice into the ocean. But guess what, it has nothing to do with CO2 and much more to do with an erupting volcanic chain underneath it:

“A very basic condition – how hot is it under the glaciers – has changed with this finding,” says Sridhar Anandakrishnan, a glaciologist at Pennsylvania State University in University Park. “Anyone who wants to model the ice flow of West Antarctica in future must take this into account.”[3]

It doesn’t take a rocket scientist (or maybe it does) to figure out that if you have one of Antarctica’s biggest volcanoes sitting under the fastest-moving glacier, the two events ‘may’ be linked.

A further clue to this is that scientists know that whatever triggered Pine Island Glacier’s race for the sea, it happened during a time of global cooling more than 40 years ago, long before greenhouse gases were an issue, and it was big enough to unhook the glacier from a ridge holding it in place:

“We do not know what kick-started the initial retreat from the ridge, but we do know that it started some time prior to 1970.”[4]

To reiterate Russel, the UN IPCC says it can only find human impact traces on the climate post 1970. Nothing we did was big enough to dislodge Pine Island glacier prior to that. Whatever is causing that glacial melt, it was natural, not human caused.

Which is pretty much what honest ice researchers will concede, if you actually ask them:

“I have a problem with the widespread implication (in the popular press) that the West Antarctic collapse can be attributed to anthropogenic climate change,” said Mike Wolovik, a graduate researcher at Lamont-Doherty who studies ice sheet dynamics. “The marine ice sheet instability is an inherent part of ice sheet dynamics that doesn’t require any human forcing to operate. When the papers say that collapse is underway, and likely to last for several hundred years, that’s a reasonable and plausible conclusion.” But, he said, the link between CO2 levels and the loss of ice in West Antarctica “is pretty tenuous.”[5]

But don’t you worry Russel, my friends in the media will probably believe you regardless, and not ask any hard questions.

You seem to be basing your predictions on a couple of alarmist papers published last month, but the UN IPCC in its latest AR5 report actually says the Antarctic appears to be reducing sea level increase rather than causing it:

“Taking all these considerations together, we have medium confidence in model projections of a future Antarctic SMB (surface mass balance) increase, implying a negative contribution to GMSL rise (see also Sections 13.4.4.1, 13.5.3 and 14.8.15).”

Then there’s your assertion about 160 billion tonnes of ice loss from Antarctica each year and that this is much higher than usual. Let’s look at that shall we. AR5 is highly sceptical (low confidence) of your claim:

“There is low confidence that the rate of Antarctic ice loss has increased over the last two decades (Chen et al., 2009; Velicogna, 2009; Rignot et al., 2011c; Shepherd et al., 2012); (4.4.2.3)”

“As with Antarctic sea ice, changes in Antarctic ice sheets have complex causes (Section 4.4.3). The observational record of Antarctic mass loss is short and the internal variability of the ice sheet is poorly understood. Due to a low level of scientific understanding there is low confidence in attributing the causes of the observed loss of mass from the Antarctic ice sheet since 1993. Possible future instabilities in the west Antarctic ice sheet cannot be ruled out, but projection of future climate changes over West Antarctica remains subject to considerable uncertainty (Steig and Orsi, 2013).” (10.5.2.1)

Again, Russel, you might be able to convince Lucy Lawless and a couple of gullible reporters, but the sorry truth is that even the UN IPCC is not making the wild claims you have in your Climate Change policy speech.

In fact, unlike you, the IPCC is not even prepared to attribute any Antarctic ice loss to human-caused climate change:

“Due to a low level of scientific understanding there is low confidence in attributing the causes of the observed loss of mass from the Antarctic ice sheet over the past two decades. {4.3, 10.5}”

As for the 160 billion tonnes figure, that’s a guesstimate based on Europe’s Cryosat overflights and which was misreported by the BBC and the American media. Other studies are showing big gains overall for Antarctica and a negative impact on sea level increase:

“The gain of almost 350 Gt (gigatons or billions of tons) from 2009 to 2011 is equivalent to a decrease in global mean sea level at a rate of 0.32 mm/yr over this three-year period.”[6]

You invite the media and the public to be scared about the resulting sea level rise, but that raises another reality check – if rising CO2 levels were genuinely causing ice to melt irreversibly around the world, sea level would be going up rapidly. Bad news for your argument – it ain’t:

“We use 1277 tide gauge records since 1807 to provide an improved global sea level reconstruction and analyse the evolution of sea level trend and acceleration.”

“The new reconstruction suggests a linear trend of 1.9 ± 0.3 mm·yr- 1 during the 20th century, with 1.8 ± 0.5 mm·yr- 1 since 1970.”[7]

In other words, sea level increase rates have not really changed over the past 100 years, no matter how many breathless reports on the TV news try and tell us otherwise.

Your 160 billion ton figures came from media mis-reporting of a couple of recent studies, which noted that Antarctica’s contribution to sea level increase had doubled from 0.19mm a year to 0.45mm a year. If that melt rate is correct, and it doubles again to 0.9mm a year, that’s a massive sea level rise of oh, I don’t know, nine centimetres over a century. In a world where tides rise and fall by six metres or more twice daily in many areas, I challenge you to pinpoint a 9cm rise in sea level.

I blame Suzanne Goldenberg in the Guardian for the outrageous hype that you repeated in your climate policy speech, and even Andy Revkin from the New York Times has called her out on it:

Study: West Antarctic Melt a Slow Affair

A new simulation of Antarctica’s most vulnerable ice sheets shows few signs of abrupt melting and sea rise.

NYT DotEarth @dotearth

In summary on Antarctic ice loss then, you’ve repeated exaggerations not backed up by peer reviewed science. Hardly a good start for a climate policy speech.

NORMAN: Then there are the floods, the wildfires, the super typhoons, the droughts and the crop failures – again, the likes of which we have not experienced in human history.

US Secretary of State John Kerry had a point when he described climate change as the “world’s most fearsome weapon of mass destruction”.[i]

WISHART:  I’m so glad you raised this Russel, because once again it looks like the Green Party has got its scientific facts wrong. When I see you referencing John Kerry rather than peer reviewed science, that might explain it. No doubt you’ll quote Al Gore at some point as well.

I would have thought you of all people would have referred to the UN IPCC report before turning your climate policy gun on your own foot, because the IPCC has found no connection between ‘floods…wildfires…super typhoons…and droughts’ that you claim:

“Current datasets indicate no significant observed trends in global tropical cyclone frequency over the past century … No robust trends in annual numbers of tropical storms, hurricanes and major hurricanes counts have been identified over the past 100 years in the North Atlantic basin”

“In summary, there continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale”

“In summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms because of historical data inhomogeneities and inadequacies in monitoring systems”

“In summary, the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global-scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century due to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice. Based on updated studies, AR4 conclusions regarding global increasing trends in drought since the 1970s were probably overstated. However, it is likely that the frequency and intensity of drought has increased in the Mediterranean and West Africa and decreased in central North America and north-west Australia since 1950”

“In summary, confidence in large scale changes in the intensity of extreme extratropical cyclones since 1900 is low”

If the most recent IPCC report[8] is dropping the “extreme weather” claims as fast as it possibly can, why on earth are you still pitching this rubbish to the public and my fellow journalists?

NORMAN:  In the midst of all this, the Intergovernmental Panel on Climate Change has released three ground-breaking new reports.

Let me summarise them for you in three points:

1) Things are worse than previously thought. The world is at risk of genuine catastrophe.

2) New Zealand is already being affected by extreme weather from climate change, and worse is to come, with serious risks to our agriculture, tourism, coastal settlements and native species.

3) Avoiding climate catastrophe remains doable and eminently affordable, as long as all countries begin the transition to a carbon efficient economy with some urgency.

Already in New Zealand, climate change is not coming cheap. Insurance companies paid out $174 million in costs for weather-related events last year. Drought in New Zealand during the first five months of last year cost the economy $1.6 billion.

At Fox Glacier, jobs are being lost along with the ice. You can no longer walk up the valley and climb the glacier face due to its retreat. The only way to reach it is by helicopter. Thirty people have lost their jobs as a result.[iii]

WISHART: As you have now learned, Russel, the AR5 report found no evidence linking so-called ‘extreme weather’ to CO2 emissions globally, so trying to sneak New Zealand in on that basis is ridiculous. I know there are some silly NZ scientists trying to argue the link, but they have no hard evidence to base it on.

Fox Glacier, incidentally, advances and retreats on a regular basis. Overall, its gradual retreat is linked to the end of the Little Ice Age in the mid 1800s. The world has warmed since then naturally and glaciers worldwide have generally been in retreat from their LIA maximum positions.

As for worse than ever, you would be referring to AR5 forecasts based on the computer modelling they relied on. Sadly AR5 credibility on its computer modelling was trashed in peer-review even before AR5 was published, as the statistical analysis the IPCC used for modelling was more than a decade out of date.

Additionally, the IPCC’s whizz-bang computers stunningly failed to predict the statistically significant 17 year pause in global warming (did you know that most teenagers have never experienced “global warming”, and that in fact temperatures have been on a cooling trend since 2003?). I raised these problems in my new book “Totalitaria”. You should read it, you might get some tips.

In case you are tempted to try and bluff your way out of the “pause” issue by calling me a denier, here’s a peer reviewed quote from the journal Nature that confirms it:

“Despite the continued increase in atmospheric greenhouse gas concentrations, the annual-mean global temperature has not risen in the twenty-first century, challenging the prevailing view that anthropogenic forcing causes climate warming.”[9]

What little global warming we have seen now appears – according to the latest peer reviewed science – to be mostly natural in origin, a result of multi-decadal and centurial heat circulation cycles in the oceans.

Each northern hemisphere winter since 2009 has been bitterly cold, and researchers have been struggling to understand why temperatures have failed to rise in line with global warming predictions and continuing growth in CO2 emissions.

Now, we have an explanation.

New research from respected climate scientist Mojib Latif and others shows the big warming periods like the late 1970s through the nineties, previously thought by climate scientists to have been caused by CO2, were in fact most likely caused by natural cycles in the oceans, or what Latif calls “climate shifts”.

This is particularly important, because the last IPCC report in 2007 said it could only detect a possible “human signature” in climate change since the 1970s. That claim was based on the assumption CO2 was the primary driver. The latest research shows CO2 had little if anything to do with warming since that time. Ergo, the “human signature” detected by the IPCC scientists does not appear to exist.

“These shifts…have a profound effect on the average global surface air temperature of the Earth,” Latif says in a news release on his study. Changes in oceanic patterns turn “the world’s climate topsy-turvy and are clearly reflected in the average temperature of the Earth.”[10]

This horrific little discovery implies that any warmer Antarctic oceans or air temperatures that you say underpin your climate policy are caused by natural forces, not humans; if parts of Antarctica are melting for non-volcanic reasons, those reasons nonetheless have nothing to do with people driving SUVs or cattle belching.

There has been no continuation of warming since 1997, making this the 17th year of a pause as I said. When Al Gore took NZ’s gullible politicians for a ride with his movie, temperatures had not only flatlined, they were four years into a cooling cycle.

Nonetheless, based on out of date computer models, climate scientists kept on giving journalists sillier and sillier climate projections.

In fact, the [IPCC] computer projections ran four times hotter for the period than the actual real observed temperature readings, as a just published report in the journal Nature Climate Change notes:

“The inconsistency between observed and simulated global warming is even more striking for temperature trends computed over the past fifteen years (1998–2012). For this period, the observed [real, measured temps] trend of 0.05 ± 0.08 °C per decade is more than four times smaller than the average simulated [computer predicted] trend of 0.21 ± 0.03 °C per decade. The divergence between observed and CMIP5- simulated global warming begins in the early 1990s.”[11]

The UN’s AR5 report was out of date even before it hit the newsstands. AR5 claims a consensus higher than “95% certainty” that human-caused CO2 emissions are predominantly driving global warming, but critics and even many scientists are now asking, “based on what evidence?” The assumptions the scientific “consensus” was supposedly built on are crumbling in the face of new evidence.

Confidence in the latest UN projections and journalistic fawning over them has not been enhanced by another new report in Nature suggesting the IPCC scientists are using statistical research techniques more than ten years out of date:

“Because the climate system is so complex, involving nonlinear coupling of the atmosphere and ocean, there will always be uncertainties in assessments and projections of climate change. This makes it hard to predict how the intensity of tropical cyclones will change as the climate warms, the rate of sea-level rise over the next century or the prevalence and severity of future droughts and floods, to give just a few well-known examples. Indeed, much of the disagreement about the policy implications of climate change revolves around a lack of certainty. The forthcoming Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) and the US National Climate Assessment Report will not adequately address this issue. Worse still, prevailing techniques for quantifying the uncertainties that are inherent in observed climate trends and projections of climate change are out of date by well over a decade. Modern statistical methods and models could improve this situation dramatically.”[12]

I find it deeply ironic and more than a little worrying that climate Chicken Littles like the Green Party have strayed so far from the path of truth on climate that sceptics are actually having to quote a flawed UN IPCC report at people like yourself in order to inject some reality back into all the breathless misinformation the Greens are feeding the news media with.

In summary, if the factual arguments you make to support your climate policy are so full of inaccuracies and exaggerations and bad science, what faith can New Zealanders have in the Green Party overall?

I’ve laid out a summary of my evidence. Where’s yours?

  1. Wow! What a one sided debate. it looks to me that Russel Norman was not given right of reply to any of Ian Wisharts’ rant. Ian appears to have taken a speech and de-constructed it, assailing each point at leisure, and attempting to make this appear as an interactive debate. It is not. This is not journalism, it is propaganda! Please, if you want to be credible and truly investigative, you MUST provide ballance! That is utterly lacking here.
    Yours aghast,
    Matt

  2. I totally agree with Matt. Rubbish Journalism. But to be expected coming from Wishart, the Christian Fundamentalist, Conspiracy Theorist looney.

  3. You are right. Unless Norman really had nothing to say. But as a greenie, I highly doubt that. I can’t believe there are still people who are totally ignorant. I am sure there are few points incorrect when it comes to climate change, but to act as if we are not destroying our world is totally insane. And these scientists make a fortune somtimes. It disqusts me.

    I think most people believe and realise climate change, but most don’t want to take own responsibility if it would effect their way of living. So we just keep on going….. (I am not totally innocent myself).

  4. Wow yourself…all three of you have avoided actually acknowledging the science and instead moaned about Russel not being able to reply. Sure he is, my final question was ‘where’s your evidence?’.

    Of course, if you guys could read you’d see it’s a slam dunk anyway. Russel and the Greens have been caught blatantly making claims not backed up by the science. End of.

  5. Re Matt, Jamie & Berry,

    While it is true the Ian dominated the debate, the responses of the candidate shows the poor preparation of the Green Party in terms of addressing evidence as a means of standing on a political platform.

    Scientific evidence is beyond moral and political consideration. Taking a political position, and using the same position as means of running for public representation in the parliament, is a position fraught with danger.

    I remain surprised that the Green Party are uninterested in promoting any positions which might benefit the natural environment of New Zealand. Here are some suggestions which I would be supportive of if the Green Party were to propose them :

    1) Complete reform of the RMA to encourage building of houses and reduce environmental overloading:
    *Concentrating a growin population of people on a smaller (and growing smaller – think about it logically) area of land, with frankly antiquated and poorly maintained waste processing systems, is a shortcut to environmental ruin in the short term. Toxins, poisons, and waste products that could normally be processed by spreading the population over a larger area, and construction of more advanced recycling and reprocessing facilities, producing more jobs, and increasing economic prosperity – I would like to see a platform suggesting glass, metal and paper recycling facilities in THIS country. Enough of this ‘Not in my back yard’ mentality.

    2) Fossil Fuel replacement:
    I would like a policy of putting down $1 Billion to build a Biobutanol plant in the Waikato to manufacture bio-butanol, which is totally compatible with high-octane petrol engines, manufacturing 500 Million litres a year from all the agricultural biological wastes collected across the country, and selling the resulting fuel for 20c a litre – forever ! All nice cars would then have nice fuel. Additional microbial products include acetone and ethanol.

    3)Support of local manufacture
    If New Zealand is contributing to pollution by having imported goods delivered, and purchasing technology that is inherently polluting during manufacture (worst culprit – the Toyota Prius), shouldn’t we then encourage local manufacture of local goods to reduce pollution and build the economy ? High technology is now cheap – Embrace 3D-CAD such as Solidworks and SolidEdge, Embrace 3D printing to allow metal casting, streamline plastics manufacture, and go nuts on electronics.
    There is now no reason we can’t print carbonfibre yacht hulls, manufacture high performance cars, and build anything we want cheaper than the Chinese, and sell overseas at a profit because New Zealanders build things with excellence, and of high desirability internationally.

    So if the Green party wanted to do all three – they’d certainly get my vote.

    But they won’t , because of their political heritage – the Greens were once Reds.

    Keep that in mind 🙂

  6. Excellent article. All verifiable. When faced with facts that show mankind is not causing global warming the only course of action left for these climate mongers is to try and shoot the messenger.
    Which just makes them look so childish.
    The Emperor has no clothes on greenies, we know AGW is not real.
    Cheers.

  7. G’day iwishart.

    First comment was spot on, you’re not doing yourself any favours when you bring up the ‘science facts’ little tidbit either.
    http://www.skepticalscience.com/global-warming-scientific-consensus-intermediate.htm
    Hear that? Even the skeptics disagree with you.

    http://www.theguardian.com/environment/climate-consensus-97-per-cent/2013/may/16/climate-change-scienceofclimatechange
    Oh look, a better journalist than you seems to disagree, too!

  8. Thanks Ian this is good to see – finally some evidence-based discussion!

    Not sure about this part of reference 2 though: ‘In general, during the study period, Vostok summer temperature varied periodically with a magnitude of ~3.58C and a wavelength of 30–50 years. In the 18th and 19th centuries the temperature decreased, and the 20th century is characterized by a positive trend’.

  9. Caleb. The Guardian? Really?…
    “UN IPCC Lead Author & University of Sussex economist Dr. Richard Tol: ‘Science is, of course, never settled.’ Tol added: ‘The 97% estimate is bandied about by basically everybody. I had a close look at what this study really did. as far as I can see, The estimate just crumbles when you touch it. None of the statements in the papers are supported by the data that’s in the paper. The 97% is essentially pulled from thin air, it is not based on any credible research whatsoever.’

  10. Excellent rebuttal of the Green nonsense. Not only are they factually in correct they used the wrong Glacier it is not Fox it is Fans Joseph that you have to fly up to (maybe) how do I know empirical evidence I walked up to Fox with hundreds of other tourist just 2 months ago. They think we should let them run the country I don’t think so. !!!!

    It is not as if they don’t have the qualified people in science they do they just let the ideology get in the way of the facts. That’s why Russia and the Eastern block countries economies failed with disastrous effects on the environment and now we have the Greens walking the same path God help us if she hasn’t been wiped out by our naturally changing climate.

    It is also worth noting that the current price of a CER to which our carbon unit is tied is $NZ 0,15 this means that he Green policy raises the price for non Dairy emitters by 167 times. The market has spoken the price of carbon has tanked and that is good for the NZ economy. The ETS never an effective policy as it was based on the very rubbish science and ideology being spouted by the Greens. The Greens solution is the same as the communists used draconian taxation yes taxation not a levy.

    I also note that BERL in their “pay for support opinion piece” to back up the Greens used a carbon price of $5.00 (2012) without any caveat. That’s very naughty for such a respected bunch of Analysts (times must be tough). The price of carbon has continued to fall since 2012 in line with the increasing realization that that the boggy man of Climate Alarmism fails the test of matching empirical data.

  11. I abhor the Green Party and in particular Red Rusty Norman. He and his socialist mates would ruin our country if they ever got within a dozen light years of the treasury books. However, this is a one sided “debate”. Don’t get me wrong… I wouldn’t waste my spit on the Green twats, but as said… one sided. I would like to see a proper debate between sensible people and the looney greens… now that would be something. CHEERS

  12. Re cataclysmic weather, the US is now into its longest period ever without a category 5 hurricane, and it just had the quietest start to its tornado season on record ( http://online.wsj.com/news/articles/SB10001424052702303603904579495581998804)

    Re sea level rise, how do they separate the measure of sea level rise from the measure of land sinking (or rising), especially for such small amounts?

    Using insurance claims as a measure is also problematic – firstly, loss of life from natural events has declined continuously for the last 100 years (notwithstanding bigger populations) indicated less severity, whereas the cost of insurance claims fluctuates based on the cost of replacement – if you build $100million in property on a riverbank where there was no property and it floods, there might be a $100million claim. How is this linked to CO2, especially if the flood is not exceptional (as per Brisbane for instance, or Sandy, a category 1 hurricane, and not even of hurricane strength when it hit shore)

    Anybody notice that the north pole is cover is now (2013) 29% bigger than a year earlier and 50% thicker (http://www.dailymail.co.uk/news/article-2415191/And-global-COOLING-Return-Arctic-ice-cap-grows-29-year.html – I know its the daily mail, but it does link to some interesting sources). Hence the need to switch the conversation to the south pole I guess.
