Australia-wide assessment: climate change or instrument change?

by J. Marohasy, April 2023 in WUWT

In the five years following the installation of probes in automatic weather stations (AWS) as they replaced mercury thermometers across Australia, the annual frequency of extremely hot days increased by an average 18.7%.

This new analysis by Perth journalist and climate researcher Chris Gillham makes a mockery of claims by the Bureau that the transition from mercury thermometers to automatic weather stations has had no effect on temperatures, and so there is no need to transcribe or make public the parallel data.

Chris has found that a majority of these AWS stations had an average 62.8% increase in their 99th percentile observations. These are the hottest 1 per cent of days calculated since the start year of each station.

Earth Day At 52: None of the eco-doomsday predictions have come true

by NetZeroWatch, Apr 22, 2023

From predicting ecological collapse and the end of civilization to warnings that the world is running out of oil, all environmental doomsday predictions of the first Earth Day in 1970 have turned out to be flat out wrong.

More than three decades before Greta Thunberg was born — the Swedish environmental activist on climate change — more than 20 million Americans participated in the first Earth Day on April 22, 1970.

We now look back at quotes from Earth Day, Then and Now,” by Ronald Bailey of the spectacularly wrong apocalyptic predictions from Earth Day 1970.

Considering the current doomsday predictions scaremonger activists are verbalizing about global warming that will result in the demise of civilization within the next decade, many of those unscientific 1970 predictions are being reincarnated on today’s social and news media outlets.

Many of the same are being regurgitated today, but the best prediction from the first earth day five decades ago, yes 50 years ago, was that the “the pending ice age as earth had been cooling since 1950 and that the temperature would be 11 degrees cooler by the year 2000”.

The 1970’s were a lousy decade. Embarrassing movies and dreadful music reflected the national doomsday mood following an unpopular war, endless political scandals, and a faltering economy.

The first Earth Day was celebrated in 1970 — okay, “celebrated” doesn’t capture the funereal tone of the event. The events (organized in part by then hippie and now convicted murderer Ira Einhorn) predicted death, destruction and disease unless we did exactly as progressives

Skepticism Of Human-Caused Climate Change Rising Globally

by C. Morrison, Apr 21, 2023 in ClimateChangeDispatch

Skepticism about human-caused climate change continues to increase around the world.

A recent poll conducted by a group within the University of Chicago found that belief in humans causing all or most climate change had slumped in America to 49% from the 60% level recorded just five years ago. [emphasis, links added]

Similar falls have been recorded elsewhere, with a recent IPSOS survey covering two-thirds of the world’s population revealing that nearly four people in every 10 believe climate change is mainly due to natural causes.

Perhaps the most surprising statistic from the Energy Policy Institute at the University of Chicago (EPIC) survey is that 70% of Americans are unwilling to spend more than $2.50 a week to combat climate change.

Nearly four in 10 Americans said they were unwilling to pay a couple of dimes.

Despite decades of relentless green doomsday agitprop designed to corral populations into living under a collectivist Net Zero-ordered society, it appears that the vast majority of Americans are unwilling to pay even the chump change in their back pockets to stop climate change.

Surveys such as EPIC and IPSOS speak to the fundamental flaw in the ‘settled’ science surrounding the suggestion that humans burning fossil fuels are causing the climate to break down.

The hypothesis is unproven – not a single science paper provides conclusive proof.

Natural causes and the proposition that carbon dioxide becomes ‘saturated’ beyond certain atmospheric levels are more convincing explanations for scientific observations.

Fears that mainstream climate science is heavily corrupted by faulty data, pseudoscientific modeling, and outright political cherry-picking are becoming more widespread.


“The thinking error that makes people susceptible to climate change denial”

by E. Worrall, May 4, 2023 in WUWT

“… Climate change deniers simplify the spectrum of possible scientific consensus into two categories: 100% agreement or no consensus at all. If it’s not one, it’s the other. …”

The thinking error that makes people susceptible to climate change denial

Cold spells often bring climate change deniers out in force on social media, with hashtags like #ClimateHoax and #ClimateScam. Former President Donald Trump often chimes in, repeatedly claiming that each cold snap disproves the existence of global warming.

From a scientific standpoint, these claims of disproof are absurd. Fluctuations in the weather don’t refute clear long-term trends in the climate.

Yet many people believe these claims, and the political result has been reduced willingness to take action to mitigate climate change.

Why are so many people susceptible to this type of disinformation? My field, psychology, can help explain – and help people avoid being misled.

The allure of black-and-white thinking

Close examination of the arguments made by climate change deniers reveals the same mistake made over and over again. That mistake is the cognitive error known as black-and-white thinking, also called dichotomous and all-or-none thinking. As I explain in my book “Finding Goldilocks,” black-and-white thinking is a source of dysfunction in mental health, relationships – and politics.

Climate change deniers simplify the spectrum of possible scientific consensus into two categories: 100% agreement or no consensus at all. If it’s not one, it’s the other.

Earth’s Mean Annual Temp Was Warmer 31,000 Years Ago… North Pole 22°C Warmer

by K. Richard, Apr 18, 2023 in ClimateChangeDispatch

Earth’s average annual temperature fluctuated by as much as 35°C (at high latitudes) from one millennial-scale period to the next during the last glacial period.

A recently-published 2-part study (Smul′skii, 2022a and 2022b) utilizes established orbital and insolation data to calculate Earth’s average temperature today (0 k years ago), 14.4°C, and at 25°N, 45°N, 65°N, 80°N, 0°, -25°S, -45°S, -65°S, and -80°S during 3 paleo epochs: 15.9 k years ago, 31.3 k years ago, and 46.4 k years ago. [emphasis, links added]

The Global Annual Temperature Of Earth: 14.4°C – The Same As A Century Ago

Consistent with dozens of other calculations, Smul′skii (2022a) determined the mean annual temperature of the modern period, which includes 1991-2018, ranges between 14.07 and 14.41°C.

More on Cloud Reduction. CO2 is innocent but Clouds are guilty.

by C. Blaisdell, 15 Apr 2023, in WUWT


This is a continuation of previous papers (1) and (2) on Cloud Reduction.  Further analysis of cloud data has revealed four new observations:

  1.  Mount Pinatubo ash in the atmosphere and Amazonia deforestation may be seen in the cloud data.
  2. A correlation of measured “Temperature – Dew point Temperature”, T-Td, to Cloud Cover was found.
  3. The Temperature – Dew point Temperature variable suggests Cloud Reduction has been going on before 1975.
  4. A simple model shows that Clouds either by reduced Cloud Fraction, decreased Cloud Albedo (lower reflectivity), or both can account for most of the observed Radiation and the associated Global Warming, GW.

CO2 is innocent but Clouds are guilty.


Climate change leaves a multi variable data finger print in the Atmosphere that is useful in drawing conclusions and testing theories.  The first of these finger prints is shown in Figure 1 where Cloud Cover, Temperature, Specific Humidity, and Relative Humidity (ground and 850mb) are shown on the same time scale.  None of Figure 1 graphs is a flat line any theory on GW should account for all these observations.  Figure 1 is NOAA data from “NOAA Physical Science Laboratory”, (3) average Northern and Southern Hemisphere.  In Figure 1 note that relative humidity at 1000mb is much less sensitive than the relative humidity at 850mb(where cumulus cloud are).  Cloud Data is from Climate Explorer, (11)

Another data finger-print data set is shown in Figure 2 from “Met Office Climate Dashboard” (“HadISDH” data), (4)  (station and buoy data).  Note that the Met Data has a much better relative humidity correlation.  The relative humidity is significant variable in the Dew Point temperature calculation, Figure 2 (e).

Artificial unintelligence and global warming

by Christopher Monckton of Brenchley, Apr 11, 2023 in WUWT

Despite the dire Terminator warnings from Elon Musk, Jordan Peterson and others about the dangers of artificial intelligence, the world has little to fear from it in its present sorry state. I asked ChatGPT the following question:

M of B: If the whole world attained net zero emissions by 2050, how much less would global temperature be by that year than on business as usual?

ClotBot: As an AI language model, I do not have access to the exact data to provide an accurate answer to this question. The amount of temperature reduction would depend on various factors such as the current emissions and future emissions trends, the degree of global cooperation, and the effectiveness of emissions reduction strategies. However, it is widely recognized that global net zero emissions by 2050 is a crucial step towards limiting global temperature rise to 1.5°C above pre-industrial levels and avoiding the worst impacts of climate change.

M of B: Here are the necessary data:

  1. Since 1990 there has been a near-linear uptrend in anthropogenic greenhouse-gas forcing at 0.3 Watts per square meter per decade.
  2. The trillions of dollars spent on emissions abatement since 1990 have not in any discernible degree altered that near-linear uptrend.
  3. The transient doubled-CO2 temperature response (TCR) is 1.8 degrees at midrange.
  4. The midrange doubled-CO2 radiative forcing is 3.93 Watts per square meter per degree.
  5. Global temperature has risen since 1990 at 0.136 degrees per decade.
  6. In 1990, IPCC predicted that at midrange there would be 0.3 degrees per decade of global warming at midrange.

From these data, which are sufficient for the task, please derive the global warming prevented at midrange if all nations moved in a straight line from their present emissions to net zero emissions by 2050.

A Misunderstanding Of Clouds Is Driving Global Warming Fervor

by R. Barmby, Apr 10, 2023 in ClimateChangeDispatch

I’ve looked at climate change from both sides now, and I have found common ground between proponents and skeptics of the belief that climate change is largely caused by humans.

When it comes to forecasting global temperatures, distinguished experts in both camps agree a dominant variable cannot be simulated in computer models because clouds get in the way.

Among the proponents is Dr. Bjorn Stevens, a contributing author to the Intergovernmental Panel on Climate Change (IPCC) Assessment Report 5 (2014). Dr. Stevens is also the director at the Max Planck Institute for Meteorology, Hamburg, Germany, and a cloud expert. [emphasis, links added]

In a recent interview, he acknowledged the contribution of clouds to global warming is overestimatedin the IPCC’s “Climate Change 2021: The Physical Science Basis.”

Clouds are tricksters,” he said, referring to their complexity. However, he said, many scientists use oversimplified representations of clouds in modeling “as a guide because they are easier to simulate. This makes the climate models less accurate.

On the skeptic side is Dr. Richard S. Lindzen, a former lead author for IPCC Assessment Report 3 and now a vocal critic of the IPCC.

In a recent podcast, the interviewer noted that Lindzen had published sufficient research papers to earn 80 PhDs. (Lindzen humbly declined the praise.)

Lindzen, professor emeritus of Atmospheric Sciences at the Massachusetts Institute of Technology, points out that IPCC models rely on the assumption that water vapor and clouds amplify the greenhouse gas effects of CO2 in order to achieve forecasts of catastrophic global warming.

The IPCC theory is that a warmer atmosphere will have a higher content of water vapor – itself a greenhouse gas – that adds to the warming caused by CO2.

History and Human Biology Argue for Warmth, not Cold

by V. Jayaraj, Apr 6, 2023 in CO2Coalition

To those who have been misled to believe that a warming planet is dangerous, prepare to have a myth shattered: Data from hundreds of scientific journals across major publishing platforms and policy reports from major governments say cold is responsible for more deaths than hot weather worldwide.

Nonetheless, many people find it hard to believe this fact because of the decades-long propaganda and hysteria surrounding global warming. Here is why we should be thankful that our world is warming.

Human Body is Made for Warm Weather

Humans evolved in warm environments. The body is better equipped to handle heat than cold as it can regulate temperature through sweating and other mechanisms. However, in cold weather, our bodies must work harder to maintain a normal temperature, which can lead to a variety of health problems.

Anecdotes of heart attacks induced by shoveling snow are common in northern climes. When exposed to cold temperatures, the body’s blood vessels constrict to conserve heat, which can increase blood pressure and strain the heart.

The relative dryness of cold air is irritating to airways, causing inflammation and making breathing more difficult, particularly for those with preexisting respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD).

So, it is no wonder that civilizations flourished when temperatures were higher, especially when home heating was primitive or nonexistent.

Scientists Say A 6°C Warmer-Than-Today Arctic Is ‘Optimal’ For Thermophile Species

by K. Richard, Apr 6, 2023 in NoTricksZone

Back in the Early Holocene, when CO2 levels were said to be ~255 ppm, Arctic Svalbard was warm enough to accommodate abundant numbers of thermophiles, or warmth-demanding species. Only “remnants” of these species and their habitat exist in today’s much-colder Arctic.

With the exception of a few centuries in recent millennia, today’s Svalbard (Arctic) is the most glaciated it has been in the last 10,000 years (see the blue trend line in the below chart from Brožová et al., 2023).


This region is today about 6°C colder than it was during the early Holocene (~10,000 to 8,000 years ago), a climatic period scientists characterize as an optimum, or “most favorable,” for a “rich species pool” of thermophiles.

The sea surface temperatures (SSTs) in the western Barents Sea were as warm as 13°C and “sea ice-free during most of the mid-Holocene” (Łącka et al., 2019). In contrast, today’s SST in this region are as cold as they were during the last glacial (2-4°C), when CO2 hovered near 200 ppm. Rapid double-digit SST fluctuations, varying from 3 to 13°C, have been ongoing throughout the Holocene.

NASA Data On Global Sea Ice Area Shows A Growth Equal To The Size Of Belgium Since 1982!

by P. Gosselin, Nov 30, 2021 in NoTricksZone

Global Sea Ice Area

Data analyst Zoe Phin just posted some interesting, surprising results on global sea ice area.

Data sources like the National Snow and Ice Data Center show global sea ice has been” drastically decreasing for a long time” and so we need to panic and overhaul the entire carbon economy. We hear this daily in the media.

Surprising global sea ice area findings

But Zoe has analyzed what she characterizes as a “very legitimate source” of data from NASA, (here, or here). And according to her findings, the data from these sources suggest global sea ice loss is not as dramatic as some institutes would like us to believe it is. In fact there ‘s been a gain!

Zoe plotted the data going back 40 years, from 1982 to 2021, the “Global Sea Ice Area Fraction”, which “is a proportion of the entire Earth’s surface that is ice over water.”

“As you can see, about 3.6% (on average) of our planet’s area is covered in ice over water,” reports Zoe. “In the last 40 years, ice over water has INCREASED, and not decreased, as popularly claimed.”

According to Zoe, the observed increase is equivalent to ~30,600 km², or “roughly the size of Belgium”.

Northern hemisphere sea ice area has declined

The northern hemisphere has decreased, and this has gotten lots of attention from alarmists and the media:

Real-World Observation: Increasing CO2 By 7,000 ppm Has A 0.3°C Temperature Differential

by K. Richard, Mar 30, 2023 in NoTricksZone

Surface air CO2 concentrations vary by 100s to 1,000s of ppm within a span of hours to days or weeks across the natural world. The observational evidence suggests these variations are neither driving or even causing temperature changes.

According to recent field research (Mungai, 2021) conducted in Kenya, the observed CO2 concentrations in the atmospheric air above mofette springs (8) averages 3,400-4,800 ppm. Interestingly, the temperatures associated with these high CO2 levels are “relatively low” or “cold” (~21.5 to 29.5°C) compared to ambient temperatures at other nearby sites with ~400 ppm CO2.
The study also shows that when CO2 increases from 5,253 ppm in wet season to 12,138 ppm in dry season over a mofette springs site, there is only a 0.3°C temperature differential (23.4°C vs. 23.1°C) associated with this >7,000 ppm CO2 change. The sensitivity of the surface air temperature to these extremely high CO2 variations would appear to be vanishingly small – or non-existent.

UGLY: Climate Skeptic Group Gets EVICTED from National Science Teaching Association Convention

by A. Watt, Mar 27, 2023 in WUWT

From the You can’t handle the truth! department comes this sad but predictable tale of closed minded pettiness. NSTA, is your position so strong and unassailable that you have to trample free speech rights to protect teachers from hearing alternate views? Does cancel culture now extend to the minds of educators?

From Greg Wrightstone, president of the CO2 Coalition who reports they were evicted from their paid and agreed to exhibit just minutes after the show opened. This picture shows them on their way out the door while the show is in progress.

He writes:

We had an exhibit booth and were attending the NSTA convention, but they were having none of it. We were thrown out of the NSTA annual convention yesterday for exposing their position on the teaching of climate change. Our science was not on the “Approved List” by them.

Theologian Thunberg and the pseudo-religion

by B. Muehlenberg, Mar 26, 2023 in Spectator

Imagine that: it seems that Greta Thunberg is now a top theologian…? Yes, I realise that honorary degrees are usually not worth the paper they are printed on, but in what has to be the joke of the decade, climate change activist (and some may say, alarmist) Greta Thunberg has been awarded an honorary doctorate in theology from the Theology Faculty at the University of Helsinki.

The 20-year-old Swede has already been honoured with a doctorate by the Belgian University of Mons, and was named Time’s ‘Person of the Year’ in 2019. She is held up by many as our ‘only hope’ to stop the apocalypse. About the only accolade left is to proclaim her to be the long-awaited Messiah.

Yet as far as I can tell, Thunberg does not have a theological bone in her body – certainly not any Christian ones. If that is the case, why do we have another Woke university declaring her a theologian worthy of praise? Wow, not bad for a day’s work…

The 1.5 C Temperature Fiction, Already Exceeded

by J. Marohasy, Mar 21, 2023 in WUWT

From Jennifer Marohasy’s blog

March 21, 2023 By jennifer

It is all over the news, another climate change report from the IPCC – the United Nation’s Intergovernmental Panel on Climate Change. Of course, it tells us that the end is nigh unless we do something to prevent temperatures exceeding 1.5 degrees Celsius. Meanwhile, not one of the contributors has any proven capacity to accurately forecast the weather more than a few days in advance, nor much of an idea of the quality of the temperature data inputted into the simulation models claiming the Earth is burning up. Yet they claim to be able to forecast temperatures years in advance and repeat over and over the value of 1.5 C as representing a tipping point.

The reality is that annual maximum temperatures across Australia were mostly falling, and by much more than 1.5 C, from at least 1910 to 1960 and then increasing, and by more than 1.5 C, since 1960.

There are few locations across Australia where temperatures have been recorded at the one place and using standard equipment (including in a Stevenson screen with a mercury thermometer) much before 1908. Darwin in the Northern Territory and Richmond in Queensland are special because they have long and relatively reliable temperature records. Making a single adjustment to the Darwin temperature record to correct for the move from the post office to the airport (after the post office was bombed in WW II), it is evident from the chart that both temperature series show cooling and then warming over the last century and by much more than 1.5 C over periods of less than a decade.

Barry Brill: The Climate Emperor Is Now Naked

by B. Brill, Mar 18, 2023 in ClimateRealism


The survey of 950 U.S. Likely Voters was conducted on March 6-8, 2023. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence.

The result (reported here) was breathtaking!An outright majority of those polled agreed that climate change has become a religion which has nothing to do with the climate. Almost half (47%) said they “Strongly Agree” while a further 13% said they “Agree”.

It’s hard to digest the fact that no less than 60% of US voters have now formed the clear view that the endless propaganda we hear daily from our politicians and corporate media actually has nothing to do with science or genuine alarm – it isn’t even about the climate. Instead, it’s all about political power and control.

Nearly half of those polled have strong feelings about this. That seems to suggest that they are a million miles from swallowing the orthodox narrative and are no longer persuadable. Although they weren’t asked, one can assume that they are fed up with the propaganda and want to be treated as adults.

Surprisingly, nearly half of the Democrats polled agreed that climate change has become a religion. But there was still a significant difference between the parties, the breakdown being:

Democrats:             45%

Independents:         60%

Republicans:          79%

There is no reason to believe that adult New Zealanders would feel any different from their American counterparts. And the breakdown between political parties would probably be much the same here as well.

Claim: A Majority of Voters believe Climate Change is a False Religion

by E. Worrall, Mar 15, 2023 in WUWT

But just maybe the tide is turning.

A lot of things have been going wrong for wind and solar fanatics lately. Biden, arguably the President with the greatest record of subsidizing unreliable wind and solar in America’s history, had his chance to bring down energy prices with his solar panels and wind turbines. Instead, he delivered the spectacle of the US Secretary of State crawling to the Saudis, begging for access to their oil, oil which could have been delivered by the Keystone Pipeline and other petroleum projects the Biden administration sabotaged.

In Britain and Germany – energy prices. Chancellor Olaf Scholz of Germany has implausibly promised an energy miracle, but Britain and Europe have already waited a long time for the promised reward for all the hardship they have endured and the trillion Pounds and Euros spent over the last few decades.

The measures Britain and Germany have taken to avert catastrophe in the face of Russian gas supply disruption, and the utter failure of  the climate alarmist’s energy programmes to deliver, are beyond embarrassing. Germany is bulldozing villagesold growth forests, even a wind farm to dig up coal to avoid further deindustrialization caused by their maniacal reliance on intermittent wind and solar. Britain deferred decommissioning her decrepit coal plants. Just as well, Britain needed those coal plants again just last week.

In Australia, Prime Minister Albanese, who won on the promise of a substantial drop in energy prices, well that promise is now looking pretty shaky. Household energy prices are set to rise 20%, 30% next year?Who knows. What we do know, is it will be a lot – and the dirt cheap coal power which bring down prices is scheduled to be shut down.

With the promises of the climate religion wearing thin, and climate concern faltering in the face of mortgage stress and soaring energy bills, perhaps this Rasmussen poll is what it appears to be – an early indication of a sea change in public opinion concerning climate change and climate action.

New WUWT Global Temperature Feature: Anomaly vs. Real-World Temperature

by A. Watts, Mar 13, 2023 in WUWT

One of the most frightening aspects of global warming, aka “climate change” is the graphs produced from temperature data for public consumption and trumpeted by an unquestioning and compliant media. When it comes to measuring climate, in order to actually see any temperature differences over the last century, they must be highly magnified using the temperature anomaly method.


Science Yields Surprises! Island Nations Growing… “Atoll, Island Stability Is Global Trend”!

by P. Gosselin, Mar 8, 2023 in WUWT

IPCC high-end sea level predictions for 2100 are “highly erroneous”. 

Global warming alarmists like to claim that Pacific island nations are on the verge of disappearing – due to rising sea levels caused by polar ice melting due to global warming, which in turn supposedly is caused by rising concentrations of “heat-trapping” trace gas CO2 from the burning of fossil fuels.

These coral reef island nations risk going under real soon, unless we wean ourselves from fossil fuels soon, they say.

Coral reef island nations are emerging, not disappearing

But yesterday Kenneth here presented a new paper appearing in Nature, (Kench et al., 2023), which looks at whether the coral reef islands are in fact seeing unprecedented and undergoing accelerating physical changes that risk outrunning human adaptation measures. The authors analyzed the dynamics of a Maldivian reef island at millennial to decadal timescales.

Recent changes not unprecedented

The researchers found that “island change over the past half-century (±40 m movement) is not unprecedented compared with paleo-dynamic evidence”.

Nothing unusual is happening. The global data suggest that almost all islands are in fact growing, and not  disappearing under water like climate alarmists mistakenly believe.

“Recent shoreline changes (±40 m/50 years) are ‘dwarfed’ by the shoreline changes (±200 m/100 years) that occurred throughout previous centuries,” the study’s authors write.

 89% of all the globe’s islands are stable, or growing!

Moreover, just 4 years ago, another peer-reviewed publication appearing in a renowned journal found similar results: 89% of the globe’s islands and 100% of large islands have stable or growing coasts! According to Duvat, 2019:

“88.6% of islands were either stable or increased in area, while only 11.4% contracted. It is noteworthy that no island larger than 10 ha decreased in size. These results show that atoll and island areal stability is a global trend, whatever the rate of sea-level rise.”

Moreover, Khan et al (2018) found: “Prediction of 4–6.6 ft sea level rise in the next 91 years between 2009 and 2100 is highly erroneous.”

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

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.
