Climate Money Paper




The nerds have the numbers on precious metals investments on the ASX



Does Climate Money matter? Is a monopoly good for a market?

Climate Money turned the tables on the Big-Oil criers

A reply to an article on Wired and Ars Technica

Alarmists rarely attack, or even mention the Climate Money paper I did in 2009.  It’s an own goal to draw attention to the fact that skeptics are paid a pittance, while the alarm industry soaks in extended baths of cash, grants, and junkets, and the vested interests are a magnitude larger. Exxon might lose some money if a carbon tax comes in, but the world will still need oil. The same can’t be said for ACME-Solar. If a carbon scheme falls over, so does a Solyndra.

So yes, let’s do talk about The Money. As Climate Money pointed out: all Greenpeace could find from Exxon was a mere $23 million for skeptics over a decade, while the cash cow that is catastrophic climate change roped in $2,000 million a year every year during the same period for the scientists who called other scientists “deniers”.

John Timmer tried to debunk it with words like “bogus”, and “false” but lacked things like evidence and numbers to back up his case. As far as I can tell the arguments amount to [...]

EU Carbon trading crashes: German bourse closes and Irish end carbon rort

More signs Australia is leaping onto a burning ship as it starts carbon taxing, just as the largest carbon markets are winding up:

(Reuters) – Bavaria’s stock exchange will abandon its carbon emissions certificate trading operations in the EU-traded CO2 market on June 30 after volumes in Europe “plunged to practically zero” in recent months, it said on Tuesday.

The EU’s emissions trading scheme (EU ETS) limits the carbon dioxide emissions of the 27-nation bloc’s factories and power plants and covers nearly half of EU emissions.

EU prices are down 60% over the last 12 months

“Emissions trading will never find its feet again without radical political action,” said Christine Bortenlaenger, the head of the exchange…

The Borse management claim they were closing because of the fraud and hacking as well as the market downturn:

$700,000 for believers to convert skeptics – but nothing for skeptical science

From the 2011 Australian Research Council report: as much as $45,700,000 was spent on An Environmentally Sustainable Australia in 2011.

The cash cow that is “Climate Change” is so loaded that over a six year period, $718,000 dollars of ARC funds has flowed to “believers” (their terminology) to study and convert dissenters.

The death threat that wasn’t (by the kangaroo culler — John Coochey) was made at an event that deserves more attention.  The “Deliberative Democracy” turns out to be part of a project funded by the Australian Research Council to the tune of $378,500. It’s title: Social Adaptation to Climate Change in the Australian Public Sphere: A comparison of individual and group deliberative responses to scenarios of future climate change. This year, a new version of the same project has been awarded another $340,000.

Quite properly, the deliberative forum claims it was not going to take sides:

“The project sought to engage with the full range of positions from people who are sceptical about climate change through to those who are very concerned. We do not endorse any particular point of view – it is the aim of the project to find out what these views [...]

Man-made sea-level rises are due to global adjustments

Frank Lansner’s first graph surprised me. It’s well known and often quoted that sea levels have been rising by 2-3mm a year every year for the last 20 years. But it’s not well known that the original raw satellite data doesn’t show that at all. What astonished me was the sea levels first recorded by the Topex Poseidon satellite array showed virtually no rise at all from 1993-2001. Surely not, I thought. I asked sea-level expert Nils Axel-Morner, and he confirmed: “Yes, it is as bad as that.” Now, given that Envisat (the European satellite) showed no rise from 2003-2011 (until it was adjusted) that means we have almost 20 years of raw satellite data showing very little rise. We thought satellites would finally give us a definitive answer on sea levels. Instead, like the tide gauges, and every other tool available to mankind, apparently satellites systematically underestimate the rising trends. And despite the speed of light being quite quick and all, it can take years for the data to finally arrive. Sometimes 4 or 5 (or 10 years) after the measurement was made scientists “discover” that it was wrong. Now of course, any one of these adjustments could be for very legitimate reasons and give us results closer to the truth. But the adjustments always bring data closer to the modeled trend. It’s decidedly non-random. Either there is a God who thinks teasing climate scientists is spiffy, or else there is something fishy going on, and some investigative journalists need to ask some investigative questions. Is that sea-level rise due to global warming or is it due to global adjustments? — Jo

Models get the core assumptions wrong– – the hot spot is missing

This is part of a series that Tony Cox and I are doing that references the most important points and papers, as a definitive resource about the evidence. The missing hotspot is not just another flaw in the theory, it proves the models are wrong: not just “unverified”, not just “uncertain”, but failed. Apologies to those who feel I harp on about this! This is a condensed review, squishing years of a scientific battleground down to it’s bare bones… — Jo

It is not well known that even the IPCC agrees that the direct effects of CO2 will only increase world temperatures by 1.2°C. All of the projections above that (3.3°C , 6°C  etc) come from model projections based on assumptions of what water vapor and clouds will do (these are the feedback effects of the original 1.2°C).[i] Are the feedbacks correct?

If the IPCC models are right about the feedbacks, we would see a hot spot 10km above the tropics. The theory is that with more heat, more water will evaporate and rise, keeping relative humidity constant at all heights in the troposphere. The point has been conclusively tested with 28 million weather balloons since 1959.[ii]



Blame the whites for climate change?

Back when the climate was perfect, and there was no internet, no cars, no electricity lines, and not a single evil coal fired station –  ominously, the Australian climate was changing.

Back in 1846, the population of Australia was essentially just the size of the city of Canberra (a mere 340,000 people). They all rode bikes, or horses, or walked to work; it was “Earth Hour” every hour; every plasma screen was not just on standby, it was permanently unplugged.

Yet the flooding rains were giving way to droughts, and the creeks were drying up. Aboriginals said that the climate has undergone this change “since white-man came in country.”

Stephen Goddard found the quote.

Unthreaded – I’m back (just)

I’ve returned from two weeks away around some old haunts in Canberra. It’s been fascinating.

Thanks to David T for dedicatedly migrating my whole blog to a new more secure and less expensive location (PS David, I have that visual editor again. Ta!). I have 1846 emails (and that’s after several days worth were lost). Apologies for the delays in replying and apologies to those whose messages bounced.

A nation still drawing 18,000MW in it’s sleep can’t go solar…

I’m away, so this is a good time for Guest posts. Here Tony explains that we need lots of electricity even while we sleep. I didn’t realize our electricity needs were so high at night. The lowest power use each day is still as much as 60% of the peak. That’s the base load at 3am, and solar panels and wind farms just can’t provide it. We can burn the odd $500 billion building hundreds of solar plants, but even then, we would have to go “medieval” for about 8 hours each night. Candles anyone? — Jo

There’s a message in these two diagrams that underlies every decision about national energy.


Summer power curve – Time of Day versus power consumption (MW)


These two diagrams are the most misunderstood images in the whole debate — the Load Curves for actual power consumption. These two shown here are for the whole of eastern Australia (including Tasmania and South Australia).

The top diagram shows typical consumption for a day in mid summer (Monday 30th January 2012) and the second is for a typical mid winter day (Friday 22nd July [...]

US Government *only* spent $70 billion on climate since 2008

Remember the fear of global warming is falling because skeptics are well organized and well funded by vested interests and, after all, the US government is only spending ten thousand times more than Heartland. How could they compete?

The Congressional Research Service estimates that since 2008 the federal government has spent nearly $70 billion on “climate change activities.”

Oklahoma Republican Sen. James Inhofe presented the new CRS report on the Senate Floor Thursday to make the point that the Obama administration has been focused on “green” defense projects to the detriment of the military.

The Daily Caller

Hello to all the fans of global warming who know they are right because no matter how reasonable JoNova appears to be, no matter how convincing those graphs are, she “must be paid by Big-Energy”*. I know this post won’t make the slightest, infinitesimally small difference to you, because it was never about evidence anyway, was it? There’s no evidence skeptics were well funded, just like there is no evidence of that positive feedback in the models.

But sometime, somewhere (it’s coming) the world will wake up and realize that climate cash was not just a moneystream but an ocean. Climate [...]

Glikson tells us to publish a paper – we say “the heretics have — when will you?”

Golly, but The Heretic is a play that appears to be genuinely useful art, something that actually challenges the paradigm. Brice Bosnich reviews it (see below), Andrew Glikson rails against it (so, it must be useful).

Glikson says, rightly: “Opinion and “belief” are no substitute for evidence. Those who doubt the basic laws of nature and empirical data are always welcome to submit research to peer review journals…”

To which Jo Nova says to Dr Andrew Glikson, “Skeptics can name 900 papers that support our views. And you still haven’t found that one mystery paper with observations that suggests CO2′s effect will be catastrophic eh? Is there any evidence?“

Glikson can name (as he did in our debate) hundreds of papers that are irrelevant, not based on observations, or are based on a logical fallacy. Climate models are not observations of the real world. Glikson’s faith in his theory is unscientific.

Before Glikson demands we disprove him (and we can) he needs to show he has some observations that support him. Until then, man-made global warming is just another religion.

We can’t predict the climate on a local, regional, or continental scale

This is part of a series that Tony Cox and I are doing that drills down to the most important points and papers, with proper references, as a definitive resource.The models are wrong: not just “unverified”, not just “uncertain”, but proven to have failed. — Jo

Joint Post: Tony Cox and Jo Nova

Across different regions, and different time-spans over the last century, the models fail.

Koutsoyiannis and Anagnostopolous  et al show those models can’t model the recent century, and because the models fail to predict regional and smaller scale effects it’s impossible that they could predict longer and global values.[i]

On 30 year time frames, the original observations are nothing like the models projections on a local scale. (Click to enlarge).

The models should retrospectively match the actual temperature over the past 100 years. This test of retrospectivity is called hindcasting. If a model has valid assumptions about the climatic effect of variables such as greenhouse gases, particularly CO2, then the model should be able to match past known data.

“…all the models were “irrelevant with reality” at the 30 year climate scale…”

When tested, the global climate models failed to [...]

Flashback: The Great Debate, a rare chance to shakedown the science

Dr Andrew Glikson

The litany chants“The Debate is over”, but hey where was that debate?

Could the Nova Glikson “Great Debate” be it? Surely not, you think, but debates in “climate science” are high stakes affairs, where branded climate scientists will not publicly debate well known skeptics. They know they can’t win. Instead, the closest thing we get to a real debate is a kind of debate by proxy. The heavyweights on the establishment side pretend to be above it all, but of course, they are only an email away from the man on the front line.

What started as a single pair of “Yes”, then “No” articles that started on Quadrant become a five part saga lasting more than a month. I’ve compiled it all into a PDF which can be printed or read from start to finish, and might be just the thing for fence sitters who like to read. Some people really hanker after the “back-and-forwards” answer and question format. For those that missed it, two years on, the Great Debate still remains a rare example where two opponents actually drilled down to the points that matter.

To Andrew Glickson’s credit, he did not knock back [...]


I’m travelling interstate at the moment, and with site maintenance being rather larger than usual, apologies for things being thin on the ground here. I have finally got email working again, and have been following the ever entertaining antics of the death threats that werent, the gun licence that wasn’t, and the accurate, restrained and well mannered scientists who aren’t accurate, restrained orwell mannered. I will be posting more soon.


Blogger’s speech to the NY Fed tells it like it is

Joint Post: David Evans and Jo Nova Robert Wenzel says to Federal Reserve: “Leave the Building to the Four-Legged Rats”

Finally a speech with attitude tells it like it is, at the US Federal Reserve. The speech was given by blogger Robert Wenzel in late April to the New York Federal Reserve Bank, because they invited him to speak. It deserves a read — a man who knows the details tallies up the score, and politely lays out the contradictions of the Federal Reserve at point blank range.

But it is much more than that. For the US Federal Reserve to invite Wenzel to explain Austrian economics to them is like “the team” in Australia inviting me along for lunch at the Department of Climate Change to explain why the CO2 theory ain’t too hot. If that happened (as if), what would I say? This is the nature of the choice that Wenzel faced. A slam-dunk, in the nicest possible way.

The convergence of common sense: Austrians are the skeptics of economics

Wenzel is an Austrian economist, which is like being a climate skeptic in climate change. In the 1930s, Keynesian economics took over from classical economics among the central [...]
