Friends of Science Society is critical of the IPCC SR15 report, pointing out the following:
We are in the Meghalayan, not the Anthropocene. The IPCC SR15 report claims to view climate change through “the lens of the Anthropocene.” This term is popularly used to describe a modern geological period wherein humans are assumed to have a larger impact on the world than nature. On July 13, 2018, the International Union of Geological Sciences (IUGS) issued a statement that the earth is now in the Meghalayan, a period that began 4,200 years ago. In response to questions as to why the term “Anthropocene” had not been included, at least for the past 50 years of presumed human influence, the IUGS responded that the term “Anthropocene” has not even been submitted for consideration and that the term has only sociological, not scientific relevance. The IPCC should not use this ‘lens.’
All climate models (simulations) used by the IPCC run ‘too hot’ versus observations. The computer simulations project future warming (thus being the rationale for global warming climate policies) show significantly higher temperatures than what is being observed. Only the Russian climate model and satellite/weather balloon data closely match present temperatures in the lower troposphere. This suggests that most climate models ascribe too great an effect of warming (climate sensitivity) to carbon dioxide.
This means the climate models should not be used to set public policy.
No temperature can be accurately measured to a precision of less than ±0.1°C. global temperature data is a metric of averaged and adjusted data from many sources, suggesting that a 0.5°C difference in temperature is moot and an arbitrary figure. It does not reference an actual measurement of earth’s temperature; people are being misled.
The IPCC appears to have secretly changed the definition of what constitutes ‘climate’ by mixing existing and non-existing data
The definition of ‘climate’ adopted by the World Meteorological Organisation is the average of a particular weather parameter over 30 years. It was introduced at the 1934 Wiesbaden conference of the International Meteorological Organisation (WMO’s precursor) because data sets were only held to be reliable after 1900, so 1901 – 1930 was used as an initial basis for assessing climate. It has a certain arbitrariness, it could have been 25 years.
For its recent 1.5°C report the IPCC has changed the definition of climate to what has been loosely called “the climate we are in.” It still uses 30 years for its estimate of global warming and hence climate – but now it is the 30 years centred on the present.
In case you hadn’t heard we’re all doomed, yet the world mostly yawned. This is less complacency than creeping scientific and political realism.
The U.N. panel says the apocalypse is nigh—literally. According to its calculations, global carbon emissions must fall 45% by 2030—twice as much as its earlier forecasts—and the world must wean itself entirely off fossil fuels over three decades to prevent a climate catastrophe that will include underwater coastlines and widespread drought and disease.
These reductions are “possible within the laws of chemistry and physics,” said the report’s co-author Jim Skea, and that’s a relief. But he added: “Doing so would require unprecedented changes,” and the report said some methods “are at different stages of development and some are more conceptual than others, as they have not been tested at scale.”
The latest IPCC report was a setup – a cynical ploy to produce alarmist media headlines that succeeded beautifully.
Seven days ago the Intergovernmental Panel on Climate Change (IPCC) issued a press release along with a summary of its new Special Report on Global Warming of 1.5°C.
The recently released IPCC SR15 reports (at A1) that global warming is likely to reach 1.5°C between 2032 and 2050 and (at B) will probably bring species extinction, weather extremes and risks to food supply, health and economic growth. If we are to avoid this, net CO2 emissions will need to decline by about 45% from 2010 levels by 2030, reaching net zero by 2050 (C1), followed by extensive removals (C5). The required energy investment alone will be $2.4 trillion per year.
Is this possible?
As at 2015, which was not materially different from 2010, more than half the planet’s total CO2 emissions (36Gt) were sourced from just three countries:
The following description of the climate system contains nothing that is in the least controversial, and I expect that anyone with a scientific background will readily follow the description. I will also try, despite Snow’s observations, to make the description intelligible to the non-scientist.

Conclusion
So there you have it. An implausible conjecture backed by false evidence and repeated incessantly has become politically correct ‘knowledge,’ and is used to promote the overturn of industrial civilization. What we will be leaving our grandchildren is not a planet damaged by industrial progress, but a record of unfathomable silliness as well as a landscape degraded by rusting wind farms and decaying solar panel arrays. False claims about 97% agreement will not spare us, but the willingness of scientists to keep mum is likely to much reduce trust in and support for science. Perhaps this won’t be such a bad thing after all – certainly as concerns ‘official’ science.
There is at least one positive aspect to the present situation. None of the proposed policies will have much impact on greenhouse gases. Thus we will continue to benefit from the one thing that can be clearly attributed to elevated carbon dioxide: namely, its effective role as a plant fertilizer, and reducer of the drought vulnerability of plants. Meanwhile, the IPCC is claiming that we need to prevent another 0.5◦C of warming, although the 1◦C that has occurred so far has been accompanied by the greatest increase in human welfare in history. As we used to say in my childhood home of the Bronx: ‘Go figure’.
Media Matters scrutinized the top 50 U.S. newspapers between 9 AM and noon ET on Monday and found most did not mention on their website homepages the Intergovernmental Panel on Climate Change’s Sunday release of its report on the devastating impacts of a global temperature increase of 1.5-degree Celsius (2.7-degree Fahrenheit) above the temperature of the pre-industrial era.

So the very first sentence of the SR15 Summary for Policy Makers, after the Introduction, consists of a statement which is not well supported by the totality of the available scientific literature and which is at odds with the IPCC’s own findings in the AR5 Working Group 1 Report of just 5 years ago! Not a good start. —Climate Scepticism, 9 October 2018
The Intergovernmental Panel on Climate Change (IPCC) issued a press release today. It tells us the IPCC assesses “thousands of scientific papers published each year,” and that its latest report relies on “more than 6,000 references.”
…
We therefore have no earthly reason to imagine that climate science is exempt from these kinds of problems.
If half of the scientific literature is untrue, it therefore follows that half of climate research is also untrue.
This means that 3,000 of the IPCC’s 6,000 references aren’t worth the paper they’re written on.
Today with press releases, live TV coverage and some media fanfare, the IPCC SR15 report was published. Without comment, here are the press release and “headline statements” as the IPCC sees them.
HadCRUT4 is the primary dataset used by the Intergovernmental Panel on Climate Change (IPCC) to make its dramatic claims about “man-made global warming”, to justify its demands for trillions of dollars to be spent on “combating climate change” and as the basis for the Paris Climate Accord.
But according to a groundbreaking analysis by Australian researcher John McLean it’s far too sloppy to be taken seriously even by climate scientists, let alone a body as influential as the IPCC or by the governments of the world.
“It’s very careless and amateur,” he says. “About the standard of a first-year university student.”
Among the many errors found by McLean were:
Large gaps where there is no data and where instead averages were calculated from next to no information. For two years, the temperatures over land in the Southern Hemisphere were estimated from just one site in Indonesia.
Almost no quality control, with misspelled country names (‘Venezuala” “Hawaai” “Republic of K” (aka South Korea) and sloppy, obviously inaccurate entries.
Adjustments – “I wouldn’t be surprised to find that more than 50 percent of adjustments were incorrect,” says McLean – which artificially cool earlier temperatures and warm later ones, giving an exaggerated impression of the rate of global warming.
Methodology so inconsistent that measurements didn’t even have a reliable policy on variables like Daylight Saving Time.
Sea measurements, supposedly from ships, but mistakenly logged up to 50 miles inland.
A Caribbean island – St Kitts – where the temperature was recorded at 0 degrees C for a whole month, on two occasions (somewhat implausibly for the tropics)
A town in Romania which in September 1953, allegedly experienced a month where the average temperature dropped to minus 46 degrees C (when the typical average for that month is 10 degrees C).
95% of the model runs predicted more warming than the RSS data since 1988… And this is the Mears-ized RSS data, the one in which the measurements were influenced to obtain key information (erase the pause and more closely match the surface data).
Their “small discrepancy” would be abject failure in the oil & gas industry.
The observed warming has been less than that expected in a strong mitigation scenario (RCP4.5).
Output of 38 RCP4.5 models vs observations. The graph is originally from Carbon Brief. I updated it with HadCRUT4, shifted to 1970-2000 baseline, to demonstrate the post-El Niño divergence.
In media interviews or discussions with the public, the most frequent opening challenge is; “But don’t 97% of scientists agree?” It is usually said obliquely to imply that you know a lot, and I don’t understand, but I assume you are wrong because you are in the minority. I don’t attempt to refute the statistics. Instead, I explain the difference in definitions between science and society. Then I point out that the critical 97% figure is that at least 97% of scientists have never read the claims of the IPCC Reports. How many people reading this article have read all the IPCC Reports, or even just one of them? If you have, it is probably the deliberately deceptive Summary for Policymakers (SPM). Even fewer will have read the Report of Working Group I: The Physical Science Basis. Naively, people, especially other scientists, assume scientists would not falsify, mislead, misrepresent, or withhold information. It is worse, because the IPCC deliberately created the false claim of consensus.
SPOTLIGHT: Bureaucracies put their trust in other bureaucracies.
BIG PICTURE: A few weeks back, Joanne Nova perfectly captured the position of the British Broadcasting Corporation (BBC) regarding the scandalous UN entity known as the Intergovernmental Panel on Climate Change (IPCC).
A recent internal document gives BBC journalists advice about how to report on climate matters. In Nova’s words, it declares that the “IPCC is God, can not be wrong.”
The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. These are long term values, estimated for the 261-year period 1750-2011 and they apply to the “baseline” of the Schwabe ~11-year solar (or sunspot) cycle, which we will simply call the “solar cycle” in this post. The baseline of the solar cycle is the issue since the peaks are known to vary. The Sun’s output (total solar irradiance or “TSI”) is known to vary at all time scales (Kopp 2016), the question is by how much. The magnitude of short-term changes, less than 11 years, in solar output are known relatively accurately, to better than ±0.1 W/m2. But, the magnitude of solar variability over longer periods of time is poorly understood. Yet, small changes in solar output over long periods of time can affect the Earth’s climate in significant ways (Eddy 1976) and (Eddy 2009).
The question is how does the Intergovernmental Panel on Climate Change (IPCC) determine that an increase in atmospheric CO2 causes an increase in global temperature? The answer is they assumed it was the case and confirmed it by increasing CO2 levels in their computer climate models and the temperature went up. Science must overlook the fact that they wrote the computer code that told the computer to increase temperature with a CO2 increase. Science must ask if that sequence is confirmed by empirical evidence? Some scientists did that and found the empirical evidence showed it was not true. Why isn’t this central to all debate about anthropogenic global warming?
Lets all bow to the IPCC — a modern God that shalt not be questioned. The Holy Sacred Climate Cow!
The IPCC is an unaudited and unaccountable foreign committee. Not only are no scientists paid to check its findings, now the publicly mandated BBC is making sure none of their journalists will check its findings either.
In April, the UK regulator, Ofcom, found the BBC was guilty of not sufficiently challenging Lord Lawson, a skeptic. So in response the BBC now promises they will never sufficiently challenge the IPCC. That’s “false balance” for you.
Note: Please read Part 1 before reading this — this is a continuation of that essay (a rather long continuation….).
…
Readers will have heard the line “multiple lines of evidence” attached to the attribution of anthropogenic causes. However, that phrase is used only once in AR5 SPM as “Multiple lines of evidence indicate a strong, consistent, almost linear relationship between cumulative CO2 emissions and projected global temperature change to the year 2100….” I’m sure I don’t need to point out that there is never ever evidence about the future…..They do not claim in the Summary for Policy Makers that there are multiple lines of evidence for the attribution statement that apply to the past-to-present.
The upcoming 6th IPCC Sixth Assessment Report will be a “comprehensive assessment of the science” related to climate change and published in 2022. However, don’t expect it to be “comprehensive” at all as hundreds of scientific publications showing profound impacts by sun and oceans will go ignored.
Climate science has turned into a religion that centers on a single act of faith. Human CO2 is changing our climate.
In the past it was always understood that climate was impacted by a vast array of factors, such oceanic cycles, solar cycles, aerosols, cloud cover, etc. to name a few.
COP21 does not define the scientific basis of the agreement for the warming effects of the anthropogenic emissions, but it refers to a scenario. This scenario has not been defined in the COP21, but it can be found. The scientific resource of United Nations as well as of the COP21 is IPCC. The exact specification of IPCC is (Summary for Policymakers. In: Climate Change 2014. Mitigation of Climate Change”): “Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 °C to 4.8 °C compared to pre-industrial levels (range based on median climate response; the range is 2.5 °C to 7.8 °C when including climate uncertainty)”. Even though IPCC refers to multiple scenarios in the text above, the surface temperature increase to the average value of 4.25 ⁰C means one scenario only.
Complémentairement à l’article de Donna Laframboise, il semblerait que les différents groupes de travail du GIEC n’aient pas la même définition d’un conflit d’intérêt. On peut identifier deux formes principales de conflit d’intérêt : soit l’utilisation d’une étude rédigée par un auteur ou coauteur du GIEC, ce qui revient à publier des études qu’on utilisera ensuite dans une auto-justification, (voir aussi à ce sujet un billet précédent : http://belgotopia.blogs.lalibre.be/archive/2013/01/03/methodes-interpellantes-au-sein-du-giec.html ), soit la présence en ses rangs d’un salarié de l’industrie ou d’un membre ou d’un proche d’une ONG militant dans le domaine idéologico-politique.
On se rappelle que des contributeurs du GIEC, salariés de l’industrie chimique, avaient été accusés par diverses sources de conflit d’intérêt en 2016, que dire alors de membres ou proches d’ONG militantes, qui semblent de plus en plus se substituer aux organes démocratiques dans la direction de nos sociétés…
BIG PICTURE: In November 1995, the Intergovernmental Panel on Climate Change (IPCC) declared for the first time that humans were changing the climate. Its verdict turned on a single piece of then-unpublished research. Four months after the fact, the research was submitted to a prominent journal. Three months later it was published.
The world then learned that 25% of the IPCC personnel tasked with making its most crucial determination were involved with this research. In a naked a conflict-of-interest, these nine people, led by IPCC chapter head Ben Santer, had evaluated the persuasiveness of their own fledgling scientific work – and had judged it sound enough to change history.
The record snowfalls of 2018 that are sweeping across the Northern Hemisphere and continuing the growth trend in winter snowfall levels provide yet more compelling evidence that the UN IPCC AR5 WG1 climate report and models are flawed because this report concludes that future snowfall level trends will only decline.(…)
BIG PICTURE: In 1995, a 40-year-old climate modeller named Ben Santer was in charge of Chapter 8 of the UN’s upcoming Intergovernmental Panel on Climate Change (IPCC) report. Nothing in the other 49 chapters mattered more than the question his team was expected to answer: Was global climate change wholly natural – or was it partially caused by human activity?
