New Science 2: The Conventional Basic Climate Model — the engine of “certain” warming

This is the most uncontroversial post ever put on this blog — it’s everything the IPCC would agree with and the key to their unshakable confidence.

This post is for the independent thinkers, the brains that want to know exactly where the famous, core, 1.2 °C figure comes from. That’s the number of degrees that a doubling of CO2 would bring, and it’s a figure that underlies decades of research and the figure that the big models are built around. Here, as far as we know, is the simplest, accurate reference to that reasoning and their maths. We have always assumed the 1.2 °C figure is correct, and focused on questioning the feedbacks that are assumed to drive that base figure up to  3°C (or 6°C or molten-Venus-here-we-come!)

We are not criticizing the estimate here, but this is so key and central to the whole climate-clean-green industry, and the models, it has to be laid out. This is the source of “implacable confidence” among the leading thinkers of establishment climate science. It is long past time that skeptical scientists put these details — warts and all — out in public. Dr David Evans is laying out the foundation for [...]

New Science 1: Pushing the edge of climate research. Back to the new-old way of doing science

For those of you who are die-hard puzzle solvers here to spar about cutting edge research: good news, here’s where we begin the long awaited update to Dr David Evans’ climate research. There are a few surprises, sacred cows, we did not expect we would need to challenge, like the idea of “forcings”.

Government science is stuck in a rut, strangled – trying to capture the creative genius of discovery and force it through a bureaucratic formula, like it can work to a deadline or be judged by the number of papers, or pages, or citations, or by b-grade officials. Blogs are new, but this form of independent scientific research, done for the thrill of discovery, outside institutions and funded by philanthropists, is the way science was mainly done before WWII.

For the first time we are going to explain the architecture of the inner core of the climate models, the small model at the center that the big GCM’s are built around. It is mostly a physics model, and it’s mostly “basic” and mostly right. It’s the reason for the implacable confidence of the establishment in the climate debate. But there are a couple of big problems… [...]

What’s really warming the world — NASA has no idea (Not the Sun, Never the Sun!)

In the twit-world, it’s being called Bloomberg and NASA’s “proof” that man made CO2 is causing global warming.

But it’s just a zombie rehash of the same-old routine I described in How to create a crisis graph in 6 simple steps. It’s all in the art of what you don’t say and the things you leave off the graph. This is a “NASA” graph that reduces everything about the sun to one single temperature. As if the magneto-nuclear-dynamo 1.3 million times the volume of the Earth would have a weather report that just read “still hot”. Nothing to see here…

Want to scare people with graphs? Pretend your climate models work. Ignore the missing hot spot, the pause, the record antarctic sea-ice, the lack of accelerating seas, and the utter failure of climate models to model anything before the last 150 years, as well as stuff like “rain[1]“, “ drought [2]” and “humidity[3]“. Include all the factors you can think of that don’t explain the latest bump in the squiggly line. Ignore all the factors that might like cosmic rays, solar wind, solar magnetic effects, solar spectrum cycles, lunar effects on our atmosphere, and who knows how many other potential [...]

Relentlessly shrinking climate sensitivity estimates

Remember how all the news stories keep telling us the evidence is growing and getting stronger than ever “against the skeptics”?

David Stockwell has done a beautiful graph of the value of climate sensitivity estimates that of recent climate research that Steven McIntyre discussed in detail.

The trend looks pretty clear. Reality is gradually going to force itself on the erroneous models.

Indications are that around 20202030 climate sensitivity will hit zero. ;- )

The red line is ECS — Equilibrium climate sensitivity — which means after the party is all over in years to come, in the long run, this is how much the planet responds to a doubling of CO2.

The blue line is TCR — Transient Climate Response — is an estimate of what happens in the next 20 years. It’s a short term estimate.

Obviously the big question is: What happens when climate sensitivity goes negative?

Check out NicheModelling, Stockwell’s great blog, it deserves more attention.

Maurice Newman knows more about climate models than the BOM’s Dr Rob Vertessy

In the topsy turvy world of modern science, big-government has strangled science to the point where bright outsiders know more than the fully trained “experts”.

Maurice Newman, the chairman of the P.M’s business advisory council, daringly wrote in The Australian:

“It’s a well-kept secret, but 95 per cent of the climate models we are told prove the link between human CO2 emissions and catastrophic global warming have been found, after nearly two decades of temperature stasis, to be in error.”

In Senate estimates, a Greens spokesperson asked Dr Rob Vertessy, Director of the Australian Bureau of Meteorology (BoM) on his view of this. “That is incorrect,” he said, showing how little he knows about climate models, where everyone (even the IPCC) is trying to figure out excuses for their failures. Some even invent time-travelling climate models that can finally “predict” today’s climate correctly a decade after it happened.

If Maurice Newman was wrong, he was far too generous to the climate modelers. Instead of a 95% failure rate, it’s well up over 98%. Hans von Storch et al published a paper nearly two years ago comparing models and observations of a 15 year long pause. Statistically von Storch [...]

New telescopes see magnetic flux ropes on Sun (which can’t possibly affect Earths climate).

A new telescope has peered into the Sun to see solar magnetic flux ropes for the first time. Severe flux rope twists have been described as being like “earthquakes” on the sun, and are linked to eruptions of large solar flares that change magnetic fields, and cause radiation and energetic particles to rain on Earth.

We don’t know much about solar magnetic flux ropes. We know they affect space weather, but thanks to climate experts we already “know” they can’t possibly, ever in a million years, affect Earth’s weather. Even though we’ve only just been able to see them and have no long term data on them, we have Global Circulation Climate models (which don’t include these solar factors), so we have 95% certainty that none of the particles, fields or radiation changes have much impact on Earth. They might fritz satellites, electronics and communications, but Earth’s atmosphere has no electrical component (wink), and the models “work” (kinda, sorta, apart from “the pause”, the arctic, the ocean, the antarctic, and the holocene) without any of this fuzzy solar stuff. Got that? Repeat after me. The Sun does not affect Earth’s climate. (Good boys and girls. You are fit for a [...]

2013 heatwave “virtually impossible” without logical errors and broken climate models

The Climate Council calculate the “odds” that one warm year could be as hot as it was. But those “odds” depend on a logical fallacy, major, inexplicable adjustments and models we know are broken. There are invisible assumptions underlying that claim which are documentably untrue. The “odds”  might as well be lotto results.

The fallacy is argument from ignorance, a failure of logic and reasoning like saying “X is true, because we can’t think of anything else“.

To estimate meaningful odds, scientists would have to understand the major driving factors of our climate, well enough to be able to assign probabilities to outcomes. But their models are hopelessly broken, they can’t predict a decadal average on a global or continental scale. They can’t hindcast the past “bumps” without using major adjustments to make the raw observations fit the models. They don’t know why the medieval warm period was warm, they don’t know why the Little Ice Age was cool. They don’t know why the world started warming 200 years before we poured out industrial levels of CO2. They don’t know if the mystery factors driving our climate for the last 4.5 billion years are still operating. If we can’t predict the [...]

Missing heat not in deep oceans but “found” in missing data in upper ocean instead

Two papers on ocean heat released together today. The first says the missing heat is not in the deep ocean abyss below 2000m. The second finds the missing heat in missing data in the Southern Hemisphere instead. Toss out one excuse, move to another.

The first paper by Llovel and Willis et al, looked at the total sea-level rise as measured by adjusted satellites*, then removed the part of that rise due to expanding warming oceans above 2,000 m and the part due to ice melting off glaciers and ice-sheets.** The upshot is that the bottom half of the ocean is apparently not warming — there was nothing much left for the deep oceans to do. This result comes from Argo buoy data which went into full operation in 2005. (Before Argo the uncertainties in ocean temperature measurements massively outweigh the expected temperature changes, so the “data” is pretty useless.)

Figure 2 | Global mean steric sea-level change contributions from different layers of the ocean. 0–2,000m (red), 0–700m (green), 700–2,000m (blue). The dashed black curve shows an estimate for the remainder of the ocean below 2,000m computed by removing the 0–2,000m estimate from the GRACE-corrected observed mean sea-level time series. [...]

Imaginary hottest “fingerprints” found in extreme weather by failed models

Finally, for only the 87th time, climate modellers have uncovered the definitive proof they’ve been finding in different forms every year since 1988.

They seek, and find, the most excellent propaganda they can pretend is science. Look, this is the specific handprint of non-specific climate-change! Everything bar climate-sameness is proof the climate changes. How inane? The unscientific vagueness gives this poster away as being more about propaganda than about communication of science.

… in a special edition of the Bulletin of the American Meteorological Society, examining extreme events around the world during 2013, a series of papers home in on the Australian heat waves, and identify a human influence.

Using short, noisy records, with flawed and adjusted data, it is possible to run broken climate models and show “definitively” that current heat-waves and hottest years are due to man-made emissions. And if you believe that, you could be gullible enough to be a Guardian journalist.

That is, climate models that do not include solar factors like magnetic fields, solar winds, cosmic rays, solar spectral changes, or lunar effects are able to [...]

Scientists invent time-travelling models that “might have worked”

You won’t believe… Research shows surprise global warming ‘hiatus’ could have been forecast

[The Guardian]  Australian and US climate experts say with new ocean-based modelling tools, the early 2000s warming slowdown was foreseeable. Australian and US researchers have shown that the slowdown in the rate of global warming in the early 2000s, known as a so-called “global warming hiatus”, could have been predicted if today’s tools for decade-by-decade climate forecasting had been available in the 1990s.

And I’ve got a model that would have predicted the 1987 stock market crash, the GFC, and the winner of the Melbourne Cup. What I would not have predicted is that lame excuses this transparent, would be made by people calling themselves scientists, Gerald Meehl, and repeated by people calling themselves journalists. (That’s you, Melissa Davey). Though I’m not surprised that research this weak had to be published by Nature. (Where else?)

Although global temperatures remain close to record highs, they have shown little warming trend over the past 15 years, a slowdown that earlier climate models had been largely unable to predict.

This has been used by climate change sceptics as evidence that climate change prediction models are flawed.

Imagine that, the stupid [...]
