From Record Snow To No Snow, Activist Media Use Climate Change To Stoke Fear

by J. Heller, Mar 7, 2023 in ClimateChangeDispatch

This article is in the tradition of articles that we have seen for decades saying we could look forward to snowless winters because of humans and our use of natural resources.

What is missing from every one of these articles is a direct link connecting oil consumption, CO2 content, or any other such thing with temperatures and snow. [emphasis, links added]

But the truth has never mattered to the media and other leftists when they have set out to destroy the oil industry.

They cannot explain why we had a cooling period from 1940 to 1975, where essentially the same people who are warning of an existential threat of warming were warning of an existential threat that billions would die from an existential threat of a coming ice age.

Here is a hint for sycophant journalists who just repeat what they are told.

Half The World At Risk Of Starvation Under Net Zero, Warn Top Climate Experts

by C. Morrisson, Mar 3, 2023 in ClimateChangeDispatch

Billions of people around the world face starvation if Net Zero policies ban the production of nitrogen fertilizer derived from fossil fuels.

This is the stark warning from two top American scientists who say that eliminating fossil fuel-derived nitrogen fertilizers and pesticides “will result in about half the world’s population not having enough food to eat.” [emphasis, links added]

They add that eliminating Net Zero fertilizer will create “worldwide starvation.”

In a wide-ranging paper titled ‘Challenging ‘Net Zero’ with Science‘, Emeritus Professors William Happer and Richard Lindzen of Princeton and MIT respectively, along with geologist Gregory Wrightstone, state that Net Zero – the global movement to eliminate fossil fuels and carbon dioxide and other greenhouse gases emissions – to be “scientifically invalid and a threat to the lives of billions of people”.

The battle over nitrogen fertilizer is being hard fought by green activists who argue for massive reductions in its use and more organic methods to be mandated.

This can extend to fanaticism, as marked by the Guardian’s George Monbiot, who argues for an end to dependence on farming. The ground for less choice and food is also being prepared in academia.

Recently, three barking academics operating through the University of Leeds suggested World War II rationing could be an effective way to reduce carbon emissions.

Also harking back to the days of spam and when spivs controlled parts of the supply chain was the actress Joanna Lumley, who suggested a return to a points distribution system and a form of wartime rationing.

Back on Planet Reality, the authors publish the graph below showing a “remarkable” increase in crop yieldsafter the widespread use of nitrogen fertilizer began around 1950.

The authors [point out that any present or future government actions that omit analysis of the disastrous consequences for low-income people, people worldwide, future generations, and the United States by reducing fossil fuels and CO2 for Net Zero are based on “fatally flawed science and appalling government policy.”]

Happer and Lindzen state that they are career physicists who have specialized in radiation physics and dynamic heat transfer for decades. These are said to be integral to atmospheric climate science. In their opinion, all Net Zero regulations are scientifically invalid.

The Observatory Antarctic Sea Ice: ‘The beginning of the end!’ – again

by Dr D. Whitehouse, March 2, 2023 in NetZeroWatch

…

 

CNN are not the only media outlets to report on this years’ record low sea ice around Antarctica in apocalyptic terms, other media extremists are available. For Sky News it’s the accelerating melt of polar regions. For the BBC “There is now less sea-ice surrounding the Antarctic continent than at any time since we began using satellites to measure it in the late 1970s.” All this is technically true, but misleading. When it’s put into context one sees a different picture.

So let’s have a look at the actual satellite data of Antarctic sea ice collected monthly since 1979. The NSIDCgives two data sets for what it calls i) sea ice extent, and ii) sea ice area. So let’s examine both of them.

The first graphs is sea ice area, the second sea ice extent.

From the empirical data it is evident that there is hardly any change of sea ice over the 44-year time span. Since 2016 there is a dip with possibly more variability (of which more later), and the lowest month (February) does show a record low, but by hardly anything (and also look at the data for 1992). Does this actual data look like the beginning of the end to you? Where is CNN’s 90% loss or Sky News acceleration?

Climate Expert: What The Media Won’t Tell You About Tornadoes

by R. Pielke, Feb 13, 2023 in ClimateChangeDispatch

This is the latest post in an ongoing series, titled “what the media won’t tell you about…”, which is motivated by the apparent systemic inability of the legacy media to play things straight when it comes to extreme weather and disasters.

Climate change is real and important, but its importance is not an excuse for the pervasive climate misinformation found across the legacy media. [emphasis, links added]

Here are the previous installments in the series, which are among my most popular posts and which have gone unchallenged.

What the media won’t tell you about…

Today’s post focuses on U.S. tornadoes. This year so far has seen a lot of tornadoes — 178 were reportedthrough February 11th, the 2nd most since 2005 and well above the 2005-2022 mean of 66 to date.

Of course, nowadays wherever there is extreme weather, journalists rush to claim a connection to climate change no matter what the science actually says.

For instance, after a tornado outbreak last month, the Associated Press reported that the tornadoes had been “juiced by climate change.”

Similarly, The Washington Post said that in the past it was difficult to tie tornadoes to climate change but now, “science is accumulating to support the linkage.”

Neither reported any of the data and science I share below. So, let’s take a look

Forest-Limit (Betula pubescens ssp. czerepanovii) Performance in the Context of Gentle Modern Climate Warming

by Kullman, Feb 6, 2023 in NoTricksZone

Claims the Swedish Scandes are unprecedentedly warm and tree-covered today “appear as large and unfounded exaggerations,” as the “climate and arboreal responses” of the last few decades “are still inside the frames of natural historical variation.” – Kullman, 2022 and Kullman, 2022a

Extensive birch forest fossils can be dated to the early- to mid-Holocene in northern Scandinavian regions, indicating these warmth-sensitive trees could exist in climates that are too cold for them to grow in today. This documents a much warmer period, “at least 3°C higher than during the past few decades,” 3000 to 10,000 years ago, or when CO2 was about 265 ppm (Kullman, 2022).

Contrary to modeler opinions, “there is little factual nourishment” to support modern projections that the Swedish Scandes will soon be returning to the subalpine birch forest climates of past millennia. The observed forest advancement in recent decades “is so small” that these modeling claims appear to be “unfounded exaggerations.”

Kullman, 2022

“In the southernmost Swedish Scandes, pine has already “leap-frogged” over receding the birch forest-limit (Kullman 2014, 2019). That scenario would mimic the arboreal landscape during the early Holocene and shift to a landscape unseen for thousands of years (cf. Blűthgen 1942; MacDonald et al. 2008, Macias-Fauria et al. 2012). During that epoch, summer temperatures are inferred to have been at least 3°C higher than during the past few decades.”
“At the landscape level, the obtained changes contribute to a greater and lusher landscape, in contrast to the dire conditions during the Little Ice Age, more than 100 years ago (Kullman 2010, 2015). Currently, there is little factual nourishment to flourishing projections stating that a major part of Swedish alpine areas is on verge of transformation to subalpine birch forest (e.g. Moen et al. 2004). Apparently, climate and arboreal responses are still inside the frames of natural historical variation, as inferred by several authors (e,g. Hammarlund et al. 2004; Bergman et al. 2005; Kullman 2013, 2017a, b; Kullman & Öberg 2018, 2020).”
“Given that the current relatively warm climate phase continues, the subalpine birch forest belt may eventually recede and give way to a subalpine pine belt. The obtained modest forest-limit advancement is so small that flourishing model simulations of extensive birch forest expansion over most of the current alpine tundra appear as large and unfounded exaggerations.”

Tree remnants (trunks, cones, roots, etc.) found at northern Sweden mountain sites 500 to 700 meters atop where the 21st century tree line ends imply the early-Holocene (~13,000 to 7000 years ago) climate was significantly warmer than today in this region (Kullman, 2022a).

The temperature lapse rate for the Swedish Lapland region is 0.6°C/100 m. Accounting for glacio-isostatic uplift, this tree line elevation implies surface air temperatures were 3.6°C higher than today during the Early Holocene.

Latest Mean Annual Temperature Data Show Tokyo Has Been Cooling For Decades!

by P. Gosselin, Jan 25, 2023 in NoTricksZone

TOKYO HAS COOLED OVER THE PAST 30 YEARS.
Hachijō-jima island hasn’t seen any climate change in decades!

Charts by Kirye

The mean temperature data for December, 2022, for the city of Tokyo, Japan and its Hachijō-jima island in the Pacific are now available from the Japan Meteorological Agency (JMA).

These data now allow us to look at the newest annual mean temperature trends for the two locations.

First we look at latest annual mean temperature plots for Tokyo since 1994:

Data: JMA.

According to the alarmists, the increase in CO2 is supposed to be heating up the entire planet. Strangely, using data from the JMA, Tokyo has in fact cooled modestly since 1994 – despite the urban heat sink effect from all the concrete, asphalt, steel and waste heat.

Warmth Limits For Tree Growth Affirm Austria Was 4-7°C Warmer Than Today 2000 Years Ago

by K. Richard, Jan 23, 2023 in NoTricksZone

Robust evidence from bison remains recovered from the Austrian Alps in 2020 and 2021 invalidate claims modern Alpine temperatures are unusually warm.

A new study suggests that from about 6000 to 1200 years ago European bison fed on deciduous tree/vegetation that grew at Alpine altitudes reaching around 800 m higher than they do today.

Known beech and oak tree growth warmth thresholds – the required number of days per year above a minimum temperature limit – thus affirm Austria needed to be 4-7°C warmer than now during this period (~2000 years ago).

“[T]he beech limit but also the forest line during the »wisent time« (6,000 to 1,200 years before today) was much higher and the average summer temperature had to be at least 3 to 6 °C higher than today. Remarkable is a palynological record (Ressl, 1980) from the shaft cave Stainzerkogelschaft near Lunz am See. Remains of wisent were found in the shaft (1,463 m, see Tab. 3). The clay with a skull fragment with horncores inside was examined palynologically. The dominating pollen were from alder (Alnus), oak (Quercus) and linden tree (Tilia). The oak boundary (boundary between colline and montane vegetation stages) today lies between 400 and 800 metres in the Northern Alpine Alps (Grabherr et al., 2004). Oaks (Quercus) at an altitude of 1,450 metres around 2,000 years ago also indicate a climate approximately 4 to 7 °C warmer than today.”

2022, Seventh Warmest Year: Warming Slows Down

by Andy May,  Jan 7, 2023 in Petrophysicist

No minimally informed person denies that climate changes. The climate has always changed. Since 1860 the predominant climate change has been warming, which is fortunate because if we had a winter like those of 1800-1850, we would be in for a shock. No one has been able to prove that global warming is primarily a consequence of our emissions. It is reasonable to assume that increased CO2 has contributed to warming since the mid-20thcentury when our CO2 emissions increased significantly, but no one knows how much they have contributed, no matter how much the Intergovernmental Panel on Climate Change (IPCC) insists that “humans are the dominant cause of observed global warming over recent decades.” (IPCC AR6, page 515).

There is no evidence for this statement. I know this because I have read thousands of scientific papers looking for it. And no, computer models are not evidence of anything but the programming skills of their authors. Models and their predictions are constantly changing and when our knowledge of climate changes, they must be redone.

The absolute lack of evidence contrasts sharply with the decision to cut our CO2 emissions to zero by completely changing our fossil fuel-based energy system and calling CO2 a pollutant—when it is as essential to life as oxygen. All this while most of the world doesn’t give a damn about emissions and many are only on board for the promised money.

To get to the good news about global warming we need to look at variations in the rate of global warming, i.e., the speed of warming. Today we are going to use satellite-calculated global temperature data from the University of Alabama in Huntsville, UAH 6.0. They are plotted in Figure 1.

Figure 1. UAH satellite global temperature anomaly data in °C relative to the mean from 1991 to 2020. In green is the linear trend of the series (+0.13 ºC/decade) and in blue is the linear trend since 2016. Data: UAH 6.0Graph: Woodfortrees.

As we can see, the temperature trend decreases since 2016, so 2022 is the seventh warmest year. For 7 years the planet has been cooling. Does that mean that warming is over? No, periods of 7 years of cooling are frequent in the record, there being 8 of them since 1979, and the warming continues. But there is only one period of more than 15 years of cooling, from 1998 to 2014, that appears in the record for the last 45 years. It is known as the “Pause.”

To analyze the evolution of the warming rate, we subtract from each monthly data the previous one to calculate the monthly increase. We then deseasonalize the monthly increase by finding the 12-month moving average to remove a lot of the noise. Finally, we calculate the 15-year average warming rate in °C/decade by calculating the 180-month moving average and multiplying the resulting data by 120.

What If Real-World Physics Do Not Support The Claim Top-Of-Atmosphere CO2 Forcing Exists?

by K. Richard, Dec 22, 2022 in NoTricksZone

…

 Schneider et al., 2020, NASA, UCAR, CGA

TOA greenhouse gas forcing is a fundamental tenet of the CO2-drives-climate-change belief system. And yet the “global-mean longwave radiative forcing of CO2 at TOA” (Schneider et al., 2020) may not even exist.

It is easily recognized that water vapor (greenhouse gas) forcing cannot occur above a certain temperature threshold because water freezes out the farther away from the surface’s warmth H2O goes.

According to NASA, the TOA is recognized as approximately 100 km above the surface. The temperature near that atmospheric height is about -90°C.

CO2 is in its solid (dry ice) form at -78°C and below.

Therefore, TOA CO2 radiative forcing cannot exist if CO2 cannot be a greenhouse gas at the TOA.

New Study: Greenhouse Gases May Not Be Causing 21st-Century Warming

by D. Whitehouse, Dec 16, 2022 in ClimateChangeDispatch

A new study by a team of leading climate scientists suggests that the effect of carbon dioxide this century might be small if not undetectable when compared to natural climate variability.

Global surface temperature is and always has been the key climate parameter. Whatever is happening to the Earth’s climate balance, it must, sooner or later, be reflected in the global annual average temperature, and not just in regional variations. [emphasis, links added]

But therein lies what is to some an inconvenience as the changes in the global temperature this century are open to differing interpretations including the suggestion that increases in anthropogenic greenhouse gas emissions are not needed to explain the changes we have seen in the last 20 years or so.

It’s a conclusion that many would dismiss as coming from climate “skeptics,” or downright deniers.

But what if it’s the view of scientists from two of the world’s leading institutes researching climate change; the University of Oxford and the US National Center for Atmospheric Research? Then it must be taken seriously and not dismissed offhand.

It is important research because it is the trend in the increase of global temperature caused by anthropogenic [human-caused] greenhouse gas emissions that is the most important variable for policymakers considering the scale and timescale of action in the coming decades.

However, this vital parameter is uncertain because recent decades have shown that we are living through a period of considerable natural climate variability.

Thus, a new study published in the Journal of Climate suggests the effect of carbon dioxide this century might be small if not undetectable when compared to natural climate variability.

The researchers contend that recent temperature trends might indicate that there is no detectable increase in global temperature due to greenhouse gas emissions.

While this suggestion is interesting it must be said that the researchers get themselves in a muddle when estimating temperature trends this century.

On the one hand, they acknowledge the existence of the global temperature hiatus between 2000 – 2014, but on the other hand, they do not properly distinguish the effects of the natural El Nino eventsthat have taken place in the past seven years.

This is why they conclude there might have been an acceleration in global temperature increase over this period.

They say that most of the increase is not due to greenhouse gases but to aerosol emission reductions.

The combustion of fossil fuels releases greenhouse gases but it also causes pollution that cools the Earth,offsetting any warming.

This is good news for public health as airborne particles kill several million people a year, but it also accelerates global warming.

They assess that aerosol emissions have contributed to an increase in the rate of anthropogenic warming since 2000 although they have large uncertainty.

When considering estimates of the amount of warming due to aerosol reduction along with natural climate variability, they find a solution with all the post-2000 temperature trends being due to natural variability alone.

They say (p 4283) it’s a credible hypothesis that global temperature changes since 2000 could be “arising largely from internal variability.”

Despite Alarmist Reports, Drought In The Horn Of Africa Not From Climate Change

by L. Lueken, Dec 13, 2022 in ClimateChangeDispatch

A recent article in Inside Climate News by writer Georgina Gustin leverages a tragic period of severe drought in the Horn of Africa in order to push an alarmist narrative on climate change.

Gustin claims that food security is threatened by climate change and that millions will starve as a result of it. This is false.

Data show that food security has improved over the past decades of warming. [emphasis, links added]

If there is to be a global food crisis, it won’t be climate change that causes it, but rather the heavy-handed and ultimately futile efforts at controlling the weather by regulating how people grow crops and livestock.

The piece, titled “Climate Change is Driving Millions to the Precipice of a ‘Raging Food Catastrophe’,” focuses primarily on the specific example of the severe ongoing drought in Kenya and neighboring Somalia and Ethiopia.

Ipsos: Climate Skepticism Rising Three Years in a Row

Climate change: a growing skepticism

Purchasing power is now the key priority on a global level. Despite the importance they attribute to the climate and extreme weather events, people are less inclined to become involved and are more dubious as to the human origins of the phenomenon.

Despite topping the list of environmental priorities, climate change is not generating greater concern and climate skepticism is growing

Climate change (46%, +2 points vs. 2021) and extreme climate events (43%, +2 points vs. 2021) have become the key reasons for environmental concern this year on a world level, although this is also due to the drop in concern about waste and plastic (41%, -5 points vs 2021) and air pollution (37%, -3 points vs 2021). Nevertheless, if the two items are combined, 66% of the world’s population still view the climate as a priority issue (60% in 2019).

…

In France 16-24-year-olds are less worried than the population as a whole (45%), but they are either more indifferent (16% vs 7% overall), or on the contrary express greater demoralization (38% vs 27% overall).

Unexpectedly, climate skepticism has consistently grown over the past 3 years (37%, +6 pts in 3 years), and is particularly striking in France this year (37%, +8 pts in one year)2 whereas concern about the environment is particularly strong in that country. More specifically, the idea that has progressed the most is not a denial of change, but the notion that it is “mainly due to the kinds of natural phenomena that the Earth has experienced throughout its history”. …

On one hand I’m encouraged that young people seem to be starting to break free from all the intense green brainwashing many of them experienced at school.

Having said that, the proportion of people who hold hardline alarmist views also seems to have edged up slightly – so a component of that increase in skepticism may represent an increase in polarisation.

I wish there was a way to somehow increase the rate of progress. It is sad watching people in Britain, Europe and parts of the USA suffering unnecessary hardship because political climate activism has driven up the price of energy, even if many of those people voted for the politicians who created this mess.

Electric Cars Are Futile As A Solution To The So-Called ‘Climate Crisis’

by A. Watts, Dec 9, 2022 in ClimateChangeDispatch

The Department of Energy’s Argonne National Laboratory recently released a study titled, “Assessment of Light-Duty Plug-in Electric Vehicles in the United States, 2010 – 2021,” which shows that in 2021, privately-owned plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs) “saved about 690 million gallons of gasoline.”

However, that is a huge exaggeration because fossil fuels provide 61 percent of the electricity in the United States. [emphasis, links added]

This means we have to include the inefficiency of burning coal or natural gas to make electricity(around 45 percent), transmission losses (about 5 percent), and losses in the inverter to charge the battery(another 5 percent).

Considering those losses, less than 33 percent of that apparent savings is a real reduction in fossil fuel use, the equivalent of roughly 230 million gallons of gasoline.

The Argonne study also says that from 2010 to 2021, EVs saved 2.1 billion gallons of gas. So, using the guideline of 61 percent from above, let’s be generous and say that over 11 years, EVs have saved about a third of that, the equivalent of about 750 million gallons of gasoline.

Although 750 million gallons of gasoline sounds like a huge amount, when you put into perspective the larger picture of gasoline use, that savings is actually a drop in the bucket.

According to the U.S. Energy Information Administration (EIA), “In 2021, about 134.83 billion gallons (or about 3.21 billion barrels) of finished motor gasoline were consumed in the United States, an average of about 369 million gallons per day (or about 8.80 million barrels per day).”

Using simple arithmetic, dividing those 750 million gallons of gasoline saved from 2010 to 2021 according to the Argonne Lab study, by the daily U.S. consumption of gasoline, we get 750/369 = 2.03 days.

MIT Climate Scientist Dr. Richard Lindzen Rejects ‘Climate Change’ As ‘A Quasi-Religious Movement Predicated on An Absurd ‘Scientific’ Narrative’

Dr. Richard Lindzen’s new paper: An Assessment of the Conventional Global Warming Narrative – Published by the Global Warming Policy Foundation – September 22, 2022: Climate change is “a quasi-religious movement predicated on an absurd ‘scientific’ narrative. The policies invoked on behalf of this movement have led to the US hobbling its energy system.” – “The Earth’s climate has, indeed, undergone major variations, but these offer no evidence of a causal role for CO₂.”

“Unless we wake up to the absurdity of the motivating narrative, this is likely only to be the beginning of the disasters that will follow from the current irrational demonization of CO₂.”

CO₂ is a particularly ridiculous choice for a ‘pollutant.’ Its primary role is as a fertiliser for plant life. Currently, almost all plants are starved of CO₂. Moreover, if we were to remove a bit more than 60% of current CO₂, the consequences would be dire: namely death by starvation for all animal life. It would not likely lead to a particularly cold world since such a reduction would only amount to a couple of percent change in the radiative budget. After all, a 30% reduction of solar radiation about 2.5 billion years ago did not lead to an Earth much colder than it is today, as we earlier noted in connection with the Early Faint Sun Paradox.

…

The Earth’s climate has, indeed, undergone major variations, but these offer no evidence of a causal role for CO₂. For the glaciation cycles of the past 700 thousand years, the proxy data from the Vostok ice cores shows that cooling precedes decreases in CO₂ despite the very coarse temporal resolution (Jouzel et al.,1987, Gore, 2006). Higher temporal resolution is needed to show that warming preceded the increase in CO₂ as well (Caillon et al, 2003). For earlier variations, there is no suggestion of any correlation with carbon dioxide at all, as shown in Figure 9a, a commonly presented reconstruction of CO₂ levels and ‘temperature’ for the past 600 million years or so.

Chicken Little Propaganda Dressed Up As Science

by P.  Ridd, Nov 26, 2022 in InstitueofPublicAffairs

ORIGINALLY APPEARED IN THE AUSTRALIAN

The Bureau of Meteorology and the CSIRO have delivered their ­biennial dose of depression about the climate, but their report ignores a slew of positive environmental changes.

The Bureau of Meteorology and the CSIRO have delivered their ­biennial dose of depression about the climate in their latest State of the Climate report. The climate has warmed by 1.5C and there is barely a single benefit – it is all ­disaster.

It is often said, “if it is too good to be true, it probably is” and you are being conned. What about too bad to be true? Can a gently warming climate have no significant benefits at all? The only marginally encouraging part of the report is about northern Australia. There might have been a slight reduction in cyclone numbers, and there has been a bit more rain in the recent decades.

Apart from that, the report reads like the Book of Exodus – one disaster after another. Only the frogs and boils are missing.

But it is significant that the period when Egyptians were building pyramids, which was hotter than today’s climate, is often called the Holocene Climatic Optimum. The word “optimum” was an indication that scientists working in the era before climate alarmism could see some advantage of a warmer climate.

A sure sign that the report tries too hard to find disaster is when it discusses coral bleaching and the Great Barrier Reef. It stresses that there have been four bleaching events in the past six years, which it implies were devastating. But for some reason the report fails to mention that this year the reef recorded its highest amount of coral since records began in 1985.

This proves that all the hype about the coral loss from bleaching was greatly exaggerated. But the report writers were obviously ­untroubled by the contradictory evidence. They ignored it.

“There’s No Emergency” – Dissident Climatologist Dr Judith Curry on Climate Change

by J. Curry, Nov 26, 2022 in WUWT

There are particular fields in which those that stray from the official narrative are instantly shunned as dissidents. Climate change is one of these. Dr Judith Curry, Professor Emeritus and former chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology, has become known as one of the outspoken scientists who doubt the “scientific consensus” on climate change. As a result, she was “academically, pretty much finished off” and “essentially unhirable”. However, this didn’t slow down the bold climatologist.

BizNews spoke to Curry about her views on climate change and the impact that human beings have had on the planet. A delightfully fascinating discussion ensued in which Curry explained her objection to the “manufactured consensus of scientists at the request of policy makers” and how far reality really is from the grim picture painted by environmental activists. Curry made sense of recent extreme weather events and indicated that “Earth has survived far bigger insults than what human beings are doing”. An eye-opening interview.

Study Finds The CO2 Greenhouse Effect Is Real…But Dangerous Global Warming From Rising CO2 Is Not

by K. Richard, Nov 24, 2022 in NoTricksZone

German physicists claim to have experimentally demonstrated the greenhouse effect from greenhouse gases like CO2 and CH4 is a real phenomenon, but assess the climate sensitivity to a doubling of CO2 with feedbacks is “only ECS = 0.7°C … 5.4x lower than the mean value of CMIP6 with ECS = 3.78°C.”

“The derived forcing for CO2 is in quite good agreement with some theoretical studies in the literature, which to some degree is the result of calibrating the set-up to the spectral calculations, but independently it determines and also reproduces the whole progression as a function of the gas concentration. From this we deduce a basic equilibrium climate sensitivity (without feedbacks) of ECSB = 1.05°C. When additionally assuming a reduced wing absorption of the spectral lines due to a finite collision time of the molecules this further reduces the ECSB by 10% and, thus, is 20% smaller than recommended by CMIP6 with 1.22°C.”
“Detailed own investigations also show that in contrast to the assumptions of the IPCC water vapor only contributes to a marginal positive feedback and evaporation at the earth’s surface even leads to a significant further reduction of the climate sensitivity to only ECS = 0.7°C (Harde 2017 [15]). This is less than a quarter of the IPCC’s last specification with 3°C (see AR6 [1]) and even 5.4x lower than the mean value of CMIP6 with ECS = 3.78°C.”

Climategate: Never Forget (12th anniversary)

by Master Source, Nov 22, 2022 in WUWT

 

“The growth of the technical skeptical blogosphere (pioneered by Steve McIntyre) has challenged traditional notions of expertise, i.e. credentials and sanctity of journal publications, through Climate Audit’s blogospheric deconstruction of many publications, particularly related to paleo proxies. “–Judith Curry.

By Robert Bradley Jr. — November 22, 2022

“There is no doubt that these emails are embarrassing and a public-relations disaster for science.” – Andrew Dessler, “Climate E-Mails Cloud the Debate,” December 10, 2009.

It has been 12 years since the intellectual scandal erupted called Climategate. Each anniversary inspires recollections and regurgitation of salient quotations. These quotations speak for themselves; attempts of climate alarmists to parse the words and meaning distracts from what was said in real-time private conversations.

And the scandal got worse after the fact when, according to Paul Stephens, “virtually the entire climate science community tried to pretend that nothing was wrong.” Whitewash exonerations by the educational institutions involved and scientific organizations– was a blow to scholarship and standards as well. The standard of fair, objective, transparent research was sacrificed to a politically correct narrative about the qualitative connection between CO2 forcing and temperature (see Wiki).

Fred Pearce’s The Climate Files: The Battle for the Truth About Global Warming (2010) was a rare mainstream-of-sorts look at the scandal. Michael Mann is the bad actor, despite his I-am-the-victim take in his account, The Hockey Stick and the Climate Wars (2012). [1]

Background:

On November 19, 2009, a whistle-blower or hacker downloaded more than 1,000 documents and e-mails from the Climatic Research Unit (CRU) at East Anglia University (United Kingdom). Posted on a Russian server, these documents were soon accessed by websites around the world to trigger the exposé.

These e-mails were part of confidential communications between top climate scientists in the UK, the United States, and other nations over a 15-year period. The scientists involved had developed surface temperature data sets and promoted the “Hockey Stick” global temperature curve, as well as having wrtten/edited the Intergovernmental Panel on Climate Change (IPCC) physical-science assessment reports.

Branded “Climategate” by British columnist James Delingpole, the emails provided insight into practices that range from bad professionalism to fraudulent science. Bias, data manipulation, dodging freedom of information requests, and efforts to subvert the peer-review process were uncovered.

Some of the more salient quotations follow.

Willie Soon speaks at the University of Chicago

by Andy May, Nov 20, 2022 in WUWT

Dr. Willie Soon gave a great presentation at the Federalist Society Chapter at the University of Chicago Law School on November 18, 2022. The title of his talk is:

“The Corruption of Environmental Rulemakings at the US EPA: Climate Change, Mercury Emissions, and Air Quality”

Willie Soon, 2022

Dr. Soon’s slide deck is excellent reading and he has kindly sent it to me, you can download it here. If you prefer to watch his presentation, you can do so on YouTube here. Soon’s presentation starts about 22:46 minutes into the video.

Soon’s key points:

  • Given the daily, seasonal, and annual range of temperatures around the Earth, the warming of the past 125 years is trivial.
  • Except for ENSO variations, the global average surface temperature has hardly changed in over 20 years.
  • Willie humorously dismantles the article on him in Wikipedia and Gavin Schmidt’s criticisms, these slides are worth the download!
  • Willie plugs the article he wrote with 23 co-authors entitled: “How much has the Sun influenced Northern Hemisphere Temperature trends? An ongoing debate.” Seriously, this is probably the best climate change article written in the last thirty years in my humble opinion, I refer to it all the time. The bibliography alone is worth it. If you never read another climate article in your life, you should read this one. Download it here.
  • He destroys the Mercury pollution nonsense that is permeating the media. Possible spoiler, don’t drink Coca Cola!
  • Is it air pollution or weather?

Finally, President Dwight Eisenhower’s warning about “public policy [becoming] the captive of a scientific-technological elite” was correct:

“It is time to face a hard truth: the seventy-year experiment to federalize the sciences has been a failure. The task now is to prevent the Big Science cartel from further dehumanizing society and delegitimizing science. There is a second hard truth: the necessary reforms will not come from within. Rather, it will be the people and their representatives that will have to impose them. To restore science to its rightful and valuable place, break up the Big Science cartel.”

(J. Scott Turner, Professor of Biology (emeritus), SUNY College of Environmental Science and Forestry, December 10, 2021)

I wish I had said that.

Germany’s Compounding Energy Woes: Even Wind Power Industry Is “Sliding Into Crisis”

by P. Gosselin, Nov 15, 2022 in NoTricksZone

Germany’s Blackout News here reports that not only is Germany’s energy supply faltering profoundly, but so is its wind industry as well, reporting  that it is “sliding into a crisis”.

Wind energy is supposed to step in and play a key role in supplying Germany with energy as other sources get cut off. But that too is not going to plan.

“Nordex is closing its plant in Rostock, Siemens Gamesa is sliding deep into the red and at Vestas the workforce is on strike,” reports Blackout News.

Russian Temperature Records Are Not Cooperating With The CO2-Driven Climate Narrative

by K. Richard, Nov 14, 2022 in NoTricksZone

Two new studies indicate there has been no modern warming in the last centuries in western (Urals) and eastern (Kolyma) Russian mountain ranges.

A new 27,000-year temperature reconstruction assesses it was ~2.5 to 4.8°C warmer than today from 8.9-5.2 ka BP in the Ural Mountains, or when CO2 is said to have hovered in the 265 ppm range.

Summer temperatures were also warmer during the Medieval Warm Period, or from 1.2-0.7 ka BP. After a post-Medieval cool-down fostering in the Little Ice Age, the reconstructed record suggests there has been no warming since 0.5 cal ka BP, or for the last several centuries.

The smoothed temperature record shown in the study indicates there was only one brief period in the last 10,000 years that was not warmer than today.

“The reconstructed TJuly [8.9-5.2 cal ka BP] are the highest recorded, reaching up to 4.8 °C higher than today’s air temperature. … Present day T July have persisted since 0.5 cal ka BP.”

Now It’s Claimed Anthropogenic Global Warming Is Driven By Aerosol Emissions Reductions, Not CO2

by K. Richard, Nov 10, 2022 in NoTricksZone

An increase in effective radiative forcing from human activity is now said to be mostly driven by a decline in aerosol pollution, superseding the effects of CO2 emissions.

The majority of an alleged acceleration in anthropogenic global warming in the 21st century “is driven by changes in the the aerosol [effective radiative forcing] trend, due to aerosol emissions reductions” (Jenkins et al., 2022).

Abstract

Estimates of the anthropogenic effective radiative forcing (ERF) trend have increased by 50% since 2000 (+0.4W/m2/decade in 2000-2009 to +0.6W/m2/decade in 2010-2019), the majority of which is driven by changes in the aerosol ERF trend, due to aerosol emissions reductions. Here we study the extent to which observations of the climate system agree with these ERF assumptions. We use a large ERF ensemble from IPCC’s Sixth Assessment Report (AR6) to attribute the anthropogenic contributions to global mean surface temperature (GMST), top-of-atmosphere radiative flux, and aerosol optical depth observations. The GMST trend has increased from +0.18°C/decade in 2000-2009 to +0.35°C/decade in 2010-2019, coinciding with the anthropogenic warming trend rising from +0.19°C/decade in 2000-2009 to +0.24°C/decade in 2010-2019. This, and observed trends in top-of-atmosphere radiative fluxes and aerosol optical depths support the claim of an aerosol-induced temporary acceleration in the rate of warming. However, all three observation datasets additionally suggest smaller aerosol ERF trend changes are compatible with observations since 2000, since radiative flux and GMST trends are significantly influenced by internal variability over this period. A zero-trend-change aerosol ERF scenario results in a much smaller anthropogenic warming acceleration since 2000, but is poorly represented in AR6’s ERF ensemble. Short-term ERF trends are difficult to verify using observations, so caution is required in predictions or policy judgments that depend on them, such as estimates of current anthropogenic warming trend, and the time remaining to, or the outstanding carbon budget consistent with, 1.5°C warming. Further systematic research focused on quantifying trends and early identification of acceleration or deceleration is required.
