Paris agreement struggles — only 0.04% of global CO2 emissions “ratified” (1% of man-made CO2)

Map from Climate Analytics

It was all a grand theater. Greens brag that the Paris agreement was signed by “179 countries”, but it means nothing until they get 55 nations controlling 55% of the worlds (man-made) emissions. Right now, they’ve had a resounding response from no country that matters. (Forgive me Norway, with 0.14% of man-made emissions, right now, you are in a small group which includes Palestine, Palau, and North Korea.)

What they need:

Entry into force

In accordance with Article 21, paragraph 1, of the Paris Agreement, the Agreement shall enter into force on the thirtieth day after the date on which at least 55 Parties to the Convention accounting in total for at least an estimated 55 % of the total global greenhouse gas emissions have deposited their instruments of ratification, acceptance, approval or accession with the Depositary.

What they’ve got:  22 states which produce 1% of man-made emissions.

Paris Agreement - Status of Ratification

As of 2 August 2016, there are 179 signatories to the Paris Agreement.  Of these, 22 States have also deposited their instruments of ratification, acceptance or approval accounting in total for 1.08 % of the [...]

Monckton: IPCC climate models speeding out of control compared to real world

Christopher Monckton reminds us of just how badly the “experts” have failed in the last 15 years, even including the recent hottest ever El Nino months. China bombed the atmosphere with record carbon “pollution” — worse than we thought. The world though, warms sedately at a mere half a degree per century. This is what 95% certainty looks like.   — Jo

Introducing the global warming speedometer

A single devastating graph shows climate panic was unfounded

By Christopher Monckton of Brenchley

A single devastating graph – the new global warming speedometer – shows just how badly the model-based predictions made by the Intergovernmental Panel on Climate Change have failed.



Who will be the next IPCC chairman?

The last time an IPCC chair position was up for grabs was in 2001, when things were not so politicized and aggressive, and there was not so much money and power on the table. Lobbying for this role is running hot and Tony Thomas compares the five men who are standing for this role. The position will be decided by October 8, and the new chairman will presumably be influential, or at least very visible, in Paris at the UNFCCC in early December. In the elections, there is one vote per country, so it is not so much about scientific credibility (and never was, think of Pachauri) but more about the powerful voting blocks that may form with small developing nations. Given that the new chairman will be in the media frequently and soon, this post is about being prepared. No  matter who wins, I think the IPCC is unsaveable and needs to be shut down or deprived of funding as soon as possible.   — Jo

Using IPCC numbers we can expect only half a degree of warming this century. Time to Panic?

Christopher Monckton calculates below that even if we assume the IPCC and mainstream estimates are right, the warming from here to 2100 is likely to be a minor half a degree. (He doesn’t even bother to argue about whether this would be beneficial or not). Monckton just makes the point that for all the scare campaign about preventing a “two degree” apocalypse, what we are really talking about is a half degree in the next ninety years with some theoretical further warming in the centuries after that. The “two degrees” of fear is measured from the bottom of the Little Ice Age, as if that was the ideal “pre industrial” climate that we somehow want to return to.

As usual, everything about the Great Global Warming Scare falls apart under the most cursory glance, yet the billion dollar PR truck rolls on. The climate sensitivity of the IPCC dropped in Assessment Report 5 to about 2.2 C as it slowly is dragged toward a more realistic number.  The data coming in tells us that the climate feedback factors are likely net negative, so climate sensitivity is below 1°C. Hence even a  “half a degree” due to [...]

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 [...]

IPCC recycles global doom and wants a small part of everything you own

Gullible journalists are swooning today with more and glorious prophesies of disaster.

This from the team that relies on simulations that not only fail on global scales1, but they can’t predict regional2, local3, short term, continental, or polar effects4 either. They are also wrong about humidity5, rainfall6a,6b,6c, drought7 and clouds8, as well as the all-important upper tropospheric patterns too.9, 10

Speaking to the BBC earlier, Dr Pachaudri said today’s announcement was, categorically, the “strongest, most robust and most comprehensive” document that the IPCC has produced.  — BBC

They are robustly, comprehensively, and consistently wrong.  But it’s OK, they only want 0.06% of GDP (for now).

The IPCC says that the cost of taking action to keep the rise in temperature under 2 degrees C over the next 76 years will cost about 0.06% of GDP every year. Over the same period, world GDP is expected to grow at least 300%.  –  BBC

Global warming, not so bad at all really: says NIPCC report and thousands of references

I decided that the IPCC Impacts report was irrelevant speculation because it utterly depended on the IPCC science report and the climate models which we already know are wrong. But the dedicated team at NIPCC show that, even if we take the claims of “impacts” working group seriously, they still come to nothing. Atmospheric CO2 is not a pollutant, there is little risk of famine due to our emissions or due to global warming. Life in the oceans is likely to adapt reasonably well as so many studies have shown, and less humans will die overall as a bonus. For those of you who enjoy well written, well researched arguments, and especially if you are looking for scientific references and the nuance of this debate, there is much to learn. The NIPCC reports are an invaluable reference for me. Careful scientific language is so much more informative than the full-gloss IPCC double-speak about theories which are consistent with uncertainties but not with observations   – Jo

Debunking every IPCC climate prophesy of war, pestilence, famine, drought, impacts in one line

We could spend hours analyzing the new IPCC report about the impacts of climate change. Or we could just point out:

Everything in the Working Group II report depends entirely on Working Group I.

( see footnote 1 SPM, page 3).

Working Group I depends entirely on climate models and 98% of them didn’t predict the pause.

The models are broken. They are based on flawed assumptions about water vapor.

Working Group I, remember, was supposed to tell us the scientific case for man-made global warming. If our emissions aren’t driving the climate towards a catastrophe, then we don’t need to analyze what happens during the catastrophe we probably won’t get. This applies equally to War, Pestilence, Famine, Drought, Floods, Storms, and Shrinking Fish (which, keep in mind, could have led to the ultimate disaster: shrinking fish and chips).

To cut a long story short, the 95% certainty of Working Group I boils down to climate models and 98% of them didn’t predict the pause in surface temperature trends (von Storch 2013) . Even under the most generous interpretation, models are proven failures,  100% right except for rain, [...]

IPCC spin translated – the leaked Synopsis admits 97% of models fail

Joint Post: Geoff Sherrington and JoNova

The IPCC Synthesis Report first order draft has been leaked (h/t Tallbloke) . It is part of the big Fifth Assessment report  see the parts already released here. The Synthesis Report supposedly summarizes the science. In the real world the topic du jour is the plateau, pause, or hiatus in warming which the IPCC can no longer ignore. Instead the masters of keyword phrases test new bounds in saying things that are technically correct, while not stating the bleeding obvious. Luckily we are here to help them. : -)

Translating IPCC-spin:

“The rate of warming of the observed global-mean surface temperature has been smaller over the past 15 years (1998-2012) than over the past 30 to 60 years (Figure SYR.1a; Box SYR.1) and is estimated to be around one-third to one-half of the trend over the period 1951–2012. Nevertheless, the decade of the 2000s has been the warmest in the instrumental record (Figure SYR.1a).”

Translated: Yes temperatures are not rising faster as we predicted, even though more CO2 was pumped out faster than ever. Let’s ignore that this shows the models were wrong, the important thing is to [...]

IPCC says abrupt irreversible clathrate methane, ice sheet collapse are unlikely.

For years we’ve been warned via the media that there was a risk of irreversible global catastrophe. Is the IPCC stepping back from those forecasts too?  The words abrupt, irreversible, and tipping point didn’t make it into the Headline Points in 2013.

Reader Katabasis at Bishop Hill reports on the Royal Society meeting where abrupt and irreversible changes were discussed. Katabasis notes that in the IPCC Chapter 12 Table 12.4 many of the catastrophic changes being forecast are described as “unlikely” or “very unlikely” or even “exceptionally unlikely”. The only one now considered “likely” is that the Arctic might be ice free 40 years from now (which is a big step back from “ice free by 2013″ as some commentators predicted). Moreover confidence is low.

Will IPCC authors now correct Gore, Flannery, or other commentators when they tell us that CO2 emissions will probably lead to abrupt or irreversible ice sheet collapse, or collapses of the monsoonal circulation or Atlantic currents. Note the IPCC is saying “low confidence” for  long term megadroughts, and monsoon changes, which means, “we don’t know” rather than “unlikely”. But why spend billions to prevent something you have low confidence will happen?

Kill the IPCC says Judith Curry. After decades and billions there is nothing to show for it.

Kill the IPCC: After decades and billions spent, the climate body still fails to prove humans behind warming

 The IPCC is in a state of permanent paradigm paralysis. It is the problem, not the solution

The IPCC has given us a diagnosis of a planetary fever and a prescription for planet Earth. In this article, I provide a diagnosis and prescription for the IPCC: paradigm paralysis, caused by motivated reasoning, oversimplification, and consensus seeking; worsened and made permanent by a vicious positive feedback effect at the climate science-policy interface.

In its latest report released Friday, after several decades and expenditures in the bazillions, the IPCC still has not provided a convincing argument for how much warming in the 20th century has been caused by humans.

We tried a simple solution for a [...]

IPCC in denial. “Just-so” excuses use ocean heat to hide their failure.

In answer to the excuse du jour: “The Ocean ate my Global Warming”.

Now that the plateau in air temperatures has lasted for 15 years, everyone, even IPCC lead authors, can see the “90% certain” models were 98% wrong. So the IPCC now claims the heat went into the deep abyss, which they didn’t predict, can’t measure accurately, and, even by the best estimates we have, has not been anywhere near large enough to explain the missing energy.

They predicted the surface air temperature would increase, but it didn’t. (The 1990 IPCC predictions about temperatures were so wrong the trends have come in below their lowest possible estimate.) They predicted the oceans would warm more than twice as much as they actually have (as best as we can tell). They did not predict the air temperature would level out for 15 years, and the oceans would suddenly start producing “natural cooling”.

The oceans are a bit of a mystery black box

There are 1.4 billion cubic kilometers of ocean out there — it’s so big it hid a 650 km volcano until two weeks ago. Only two people have been to the bottom ever (correction, three men), and they [...]

More media pressure finally forcing the IPCC to cut the spin

The race in the media continues: The UK Daily Mail (again), The Spectator, The UK Express. The headlines the IPCC must hate  just keep coming, now in major newspapers and magazines. Finally, maybe, some of the media is starting to get it. At last also the IPCC is feeling the pressure to explain the halting of global warming and the poor performance of its climate models.

This is all well and good, but before we celebrate, ponder that if science journalists had been doing their job 10 years ago, the IPCC would have been put on the spot before before the wild evangelistic doom-fest of 2007 where national GDP points were roasted with every chapter. Billions could have been saved.

As I keep saying: The media is the problem. With good journalists, and real reporters, everything else gets better. Shine the light…

PR Wars: IPCC fights for relevance, halves warming, claims to be 95% certain of something vaguer

We are over the peak. Years late, the IPCC concedes some territory and wears headlines they must hate (“Global warming is just HALF what we said“, “We got it wrong on warming“), but PR still rules, and in the big game, this will quickly spin to a minor bump. It’s a classic technique to release “the bad news” before the main report, to clear the air for the messages the agents want to stick.

Since 2007 they’ve burned through their credibility in so many ways:  think Climategate, and getting caught pretending activist material was science, being busted for 300-year-typos like the Himalayan Glaciers, plus 15 years of no warming, no hot spot, models being wrong, droughts ending, and ice returning, all the while pouring scorn and derision on anyone who questioned them. The IPCC were being hammered and they had to change tacks. Now, for the first time, the IPCC is making a serious retreat, presumably in the hope of being able to still paint itself as “scientific” and to fight from a different trench. Anything to continue the yearly junkets and to save face. What they hope is that no one will notice that the deniers were right [...]

A Handy-Dandy Carbon Tax Temperature-Savings Calculator

 Patrick J. Michaels and Paul C. “Chip” Knappenberger have created a calculator of exactly how many degrees of global warming will be averted if the IPCC is right. I can’t think why the IPCC didn’t do this before. For example, if all industrialized nations  achieve a 100% reduction  (that is, stop using coal, oil, gas, diesel, and avgas tomorrow*), then 87 years from now the world will be 0.352C cooler (assuming climate sensitivity is a high 4.5C and the models work, and nothing else changes in the atmosphere). The great thing is you can adjust the parameters yourself to see how many ways Global Action does not add up.

Unfortunately it does not also project the costs. Version II perhaps?

*Please forgive me for that sweeping assumption. We all know that to get a true 100% reduction in CO2 emissions we’d need to do a lot more. Like building nuclear plants from handmade mud-bricks using solar powered trucks and wind-powered cranes. And no more flights to anywhere unless you have a pedal powered hang-glider or one of those marvelous solar planes that takes 2 months to cross the US.
