NEWS: New legal approach — consumer protection laws may protect citizens against misleading BOM statements

We know there is something wrong when we pay public servants to serve us, and they provide us with temperature records that are not the same as the original data, but they won’t explain why they adjusted them. We know the system is rotten when the inexplicable adjustments are used as an excuse to take even more money. We’ve tried FOI to get the information, but they ignore it. We’ve asked the National Audit Office to audit the records, but the people who adjusted the records are essentially the same ones who control them, so they just changed the records again, and said the audit request applied to a set they did not use now.

Today we announce a new approach –  Anthony Cox and others are pursuing the legal option. It’s a creative strategy  — he‘s approaching this through consumer protection laws.

Is there a chance consumers could be misled by reports that don’t include the uncertainties? We think so. – -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]

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 [...]

Has CO2 warmed the planet at all in the last 50 years? It’s harder to tell than you think.

Joint Post: Jo Nova and Tony Cox

Even most skeptics agree that the world has been warming during the last 50 years, but there is apparently no significant underlying warming trend in 46 out of 47 years of data. Something decidedly unusual happened to the world in 1977 and we don’t know for sure what it was. The world got warmer, and the change “stuck”. But there were no extra emissions of CO2 in that year, so there is no reason to pin this to CO2.

It’s difficult to believe we are not sure – but the last 50 years of warming trend depends on that single stepwise leap in 1977. Look at the graph below. Does it show one strong underlying warming trend, or is it really a trend so insignificant that it wouldn’t exist if there was not a step change that artificially bolstered it?

A series of two flat lines can appear to be a continuous warming trend if a linear trend line is fitted because it ignores the step change.  McKitrick and Voselgang

This step effect was first noted by David Stockwell in 2009

The continuous warming appears to be obvious in the records of [...]

The incredible power of clouds (and Roy Spencer’s work)

Joint Post by Tony Cox and Jo Nova Clouds cool the planet as it warms

Clouds cover an enormous 65% of the planet and are responsible for about half of the sunlight that is reflected back out to space.[i]  The effects of clouds are so strong that most of the differences between IPCC-favoured-models comes from the assumptions the models make about clouds. Cloud feedbacks are the “largest source of uncertainty”.[ii] Numerous studies show models project wildly different results for clouds, and yet few could correctly simulate clouds as recorded by satellites.[iii] One researcher described our understanding of cloud parameters as being “still in a fairly primitive state.” [iv]

Sunlight that travels 150 million kilometers can be blocked a mere 1km away from the Earth’s surface and reflected back to space.  The situation is complicated though, because clouds also slow the outgoing radiation — which has a warming effect. In general lower clouds are thicker and have a large cooling effect, while higher clouds are thinner and tend to trap more heat than they reflect (i.e. net warming).  Observations show the cooling effect of clouds dominates the warming effect. (Allen 2011[v]) which means that, in general, more clouds means more cooling.

Satellites show a warmer Earth is releasing extra energy to space

(I’m revisiting older important papers and setting up resource pages, largely thanks to Tony Cox’s prodding. In this post I found it interesting that Lindzen’s work, which was so controversial because it proved the IPCC is wrong, was in many ways merely confirming earlier results. — Jo) Guest Post: Tony Cox and Jo Nova Satellite measurements agree with the ocean heat content measurements. As the Earth warms, more radiation escapes to space.

If feedbacks are positive (as the IPCC estimates), then as the Earth warms the amount of energy being radiated to space will shrink (thus warming the Earth even further). If feedbacks are negative, as the Earth warms more energy will radiate away.

Multiple studies show that feedbacks are negative.

Lindzen and Choi analyzed short periods of warming looking for changes in the outgoing long-wave radiation leaving from the top of the atmosphere. The satellite observations show, repeatedly, that as the Earth warms, the climate system shifts and lets more of the infra red or long-wave energy out to space.[1],[2] It’s like a safety release valve. This means that the system has negative feedbacks (like almost all known long-lived or stable natural systems). The changes dampen the effects of [...]

We can lower Australian CO2 emissions by… (wait for it) building new coal plants!

A joint writing project: Jo Nova & Tony Cox,

based on an idea and research by Anton Lang (who writes as TonyfromOz at PAPundits)

It’s the paradox that will torture the Greens. What if the best way to achieve their environmental aims as well as providing jobs and power was to build more coal fired power stations? Imagine if we could reduce CO2 emissions by more than 5%, supply 24 hour baseload electricity, create jobs, and save thousands of square kilometres of Australian bush from industrial domination. Imagine if “New Coal” turned out to be the lowest cost alternative as well? Anton Lang has researched it, and Tony Cox has confirmed that the big numbers make sense with an Australian electricity company (who shall not be named). Selling the Carbon Tax in Neverland is already a public debate that’s pretzel tied in impossible contradictions, so what’s one  more unlikely twist? Possibly, just enough to get us out of a knot, or at least enough to expose the real aims of the carbon reduction plan. Old existing large scale coal fired power plants in Australia are all twenty to forty years [...]

ABC Rejects — Hansen admit the models are wrong, but alarmism gets the last word on the ABC.

ABC Unleashed knocked back this reply  (below) from Cox and Stockwell. The ABC is OK with publishing unsubstantiated smears, and doesn’t feel any need to muddy the water with inconvenient facts.

The essential point here is that Cox and Stockwell noticed that Hansen was inadvertently admitting the models have major flaws. Hansen effectively acknowledges the magnitude of the error by the models is almost half the entire forcing blamed on human emissions of CO2. Hansen thought he was making the point that it’s all awful and worse than we thought, because if aerosols have been cooling the planet more than we expected, then CO2 has been heating it more than we expected too! But in order to claim that, he had to first admit that the models (shock) had been wrong all along. In the end, it’s a speculative war of unknown fudge-factors.

Why does this matter so much?

The alarmists are always telling us that we know CO2 matters because they can’t explain the rise in temperatures without CO2. It’s all argument from ignorance and a fallacy from the beginning. Then when their models didn’t reproduce the cooling from 1945 – 1975, they “discovered” aerosols.

Billions of dollars sneaks out the door through UN committees

There are billions of dollars of money sneaking out the door of Western Nations and being used to feed the monster bureaucracy, the UNFCCC and its cohort.

In The Carbon Tax that Ate Australia Tony Cox and David Stockwell point out the Australian contributions  fly so under the radar (despite being millions of dollars) that even the Australian government seems to have forgotten they agreed to pay them.   Greg Combet, the minister for Climate Change promises “every dollar of the Carbon Tax will be given back to the people”:

Every dollar raised by the carbon price will be dedicated to supporting households with any price impacts, and supporting businesses through the transition to a clean energy economy. Because we are a Labor government, we will support the most vulnerable in our community — the people who need help the most.

But Combet in Cancun promised  10% of the Australian carbon tax as a tithe to the UN. (And there’s the $599 million as part of the Fast Start Finance program over three years that is in the pipeline.) So which commitment will the Australian government break? Or, let me guess, in the world of spin, the government can give all [...]

Announcing a formal request for the Auditor General to audit the Australian BOM

A team of skeptical scientists, citizens, and an Australian Senator have lodged a formal request with the Australian National Audit Office (ANAO) to have the BOM and CSIRO audited.

The BOM claim their adjustments are “neutral” yet Ken Stewart showed that the trend in the raw figures for our whole continent has been adjusted up by 40%. The stakes are high. Australians could have to pay something in the order of $870 million dollars thanks to the Kyoto protocol, and the first four years of the Emissions Trading Scheme was expected to cost Australian industry (and hence Australian shareholders and consumers) nearly $50 billion dollars.

Given the stakes, the Australian people deserve to know they are getting transparent, high quality data from the Bureau of Meteorology (BOM). The small cost of the audit is nothing in comparison with the money at stake for all Australians. We need the full explanations of why individual stations have been adjusted repeatedly and non-randomly, and why adjustments were made decades after the measurements were taken. We need an audit of surface stations. (Are Australian stations as badly manipulated and poorly sited as the US stations? Who knows?)
