German Researcher: Doubling Of Atmospheric CO2 Causes Only 0.24°C Of Warming …Practically Insignificant

by P. Gosselin, Nov 19, 2024 in NoTricksZone

The CO2 scam and “climate denial”

German researcher concludes CO2 warming immensely exaggerated…. IR radiation of clouds considerably reduces the greenhouse effect of CO2.”

The prosperity and political stability of our countries are in grave danger. The reason for this is an ideology that claims catastrophic climate change caused by the alleged “greenhouse gas” CO2 and is intent to destroy our civilization and prosperity. Its supporters are spreading a witch-hunt atmosphere against anyone who questions their ideology. So-called “climate deniers” are also denied any scientific expertise.

Every Swiss person can already see the first financial consequences on their electricity bill: In this country, the price of a kilowatt hour has shot up by up to 300% for some households in just four years. And this is just the beginning, as the Swiss government is pursuing the goal of switching to solar and wind power and thus to sources that cost 20 instead of 6 rp/kWh.

Conclusions

In his summary, Prof. Reinhart comes to the following conclusions:

“- The heat retention (“forcing”) by atmospheric carbon dioxide (CO2 ) causes a maximum temperature increase of 0.24 K (0.24°C) when the concentration doubles from 400 ppm to 800 ppm, based on a simplified absorption model that is independent of climate.

– This value depends only on the accepted mean earth temperature, T = 288 K, and is relatively insensitive to its uncertainty of 2 K.

– The temperature increase since the industrial revolution amounts to a maximum of 0.12 K, which is within the range of measurement accuracy. The anthropogenic contribution is therefore practically insignificant.

– The behavior of glacial and current temperature trends is not causally linked to carbon dioxide concentrations.

– The causes of global warming have not been clarified. However, they are most likely linked to the solar system and the water cycle.

– Measures to control CO2 emissions and the earth’s temperature are unsuitable, even dangerous means”.

From The Alps To Australia To Europe And More, Cold Is Wreaking Havoc Globally

by P. Gosselin, May 30, 2023 in ClimateChangeDispatch

1. Alaska’s fourth cold winter in a row

Alaska was once seen as a beacon of hope in the AGW coal mine: but after four cold winters in a row, culminating in a historically cold winter season in 2022-23, the Last Climate Frontier has certainly lost that status – the catastrophists will now have to look elsewhere to bolster their narrative.

According to NOAA’s data, and despite the agency’s official forecasts that consistently heralded “warmer than average” seasons, the last four winters in Alaska have shown a strong cooling trend. [emphasis, links added]

The Old Farmer’s Almanac is also off its rocker. It predicted a “much milder than normal winter” for 2022-23 with below-average snowfall. That was wrong on both fronts.

Historic snowfall totals of more than 250 cm fell across much of Alaska, and Anchorage set a new record for leftover snow that stayed on the ground well into April.

April was also a historically cold month across Alaska, with an average temperature of -8.7 degrees Celsius, which is 5.5 degrees Celsius below the multi-decadal norm, and the fourth coldest April in 99 years of NOAA records.

The snow has now continued into May, tumbling even more records.

2. More and more new cold records “Down Under”

Icy polar air masses continue to dominate large parts of Australia – most recently in the west. Moreover, a continent-wide cold air outbreak from Antarctica is expected in the second half of this week.

Australia is cooling, and the proof is in measurements: For the past six years, it has been colder than average Down Under, and the list of cities that have recorded the coldest seasons since records began is growing(such as Brisbane last winter).

May 2023 continues this cooling trend, with the lowest May temperatures on record already recorded in a number of locations early in the month – including Cooma, Omeo, Bombala, and Canberra.

In Sydney last Sunday, the lowest temperature recorded at the start of autumn in 85 years (since 1938) was 7.1°C.

Over the weekend, it was the west’s turn to freeze.

Large parts of Western Australia just experienced the coldest May morning in at least two decades. On both Sunday and Monday morning, the temperature in Broome, for example, dropped to 11.5 °C, the lowest autumn reading since 1999.

3. May snow in Europe – even in Spain

At a glance – Global cooling – is global warming still happening?

by J. Mason, May 23, 2023 in SkepicalScience

At a glance

Earth’s surface, oceans and atmosphere are all warming due to our greenhouse gasemissions, but at different rates. Some places are also warming much faster than others: parts of the Arctic for example. That variability is partly because other phenomena act to offset or enhance warming at times. A good example are the effects of La Nina and El Nino, an irregular variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean that can influence temperatures and rainfall patterns right around the world.

El Nino causes even warmer years whereas La Nina tends to peg temperatures back to an extent. Thus 2016 – an El Nino year – was the warmest year on record, according to the USA-based National Oceanic and Atmospheric Administration, but other recent years have not been far behind – 2020 and 2019 are in second and third place respectively. The worrying thing is that 2019 only saw a mild El Nino and 2020 was “neutral” – there were neither El Nino or La Nina conditions. And even with a La Nina featuring, 2021 and 2022were, respectively, still the seventh and sixth hottest years on record.

The year 1998 featured a massive El Nino and consequent temperature spike that was a strong outlier, well above the steady upward trend. That spike and the subsequent return to a more “normal” warming pattern led to claims in the popular media that global warming had “paused” or had even stopped. This was a typical misinformation tactic that, as usual, time has proved wrong. As things currently stand, the top ten warmest years have all been since 2010 and 1998 is nowhere to be seen any more. By modern standards, it simply wasn’t warm enough.

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.

“NEW LITTLE ICE AGE INSTEAD OF GLOBAL WARMING?” BY DR THEODOR LANDSCHEIDT

by Cap Allon, September 7, 2020 in Electroverse

Among the long list or scientific papers suggesting that a solar-driven spell of global cooling is on the cards, Dr Theodor Landscheidt’s ‘New Little ICE Age Instead of Global Warming?‘ probably has the claim of priority.

Published in 2003, just a year before his death, Landscheidt’s research is standing the test of time, and is still largely on course to be proved correct.

The paper’s abstract begins:

‘Analysis of the sun’s varying activity in the last two millennia indicates that contrary to the IPCC’s speculation about man-made global warming as high as 5.8C within the next hundred years, a long period of cool climate with its coldest phase around 2030 is to be expected.’

Crucially, in the growing list of research concluding that a solar-driven multidecadal spell of global cooling is on the cards (research from multiple studies of quite different characteristics), the year 2030 ALWAYS features prominently. Unlike the IPCC, which tosses its thermageddon doomsday date back and forth like a hot potato, researchers who track the multimillennial plays of the cosmos (namely those of the Sun) routinely land on the year 2030 as being the date of ‘climate deterioration’: this in itself should serve as compelling evidence.

Dr Landscheidt continues:

‘It is shown that minima in the 80 to 90-year Gleissberg cycle of solar activity, coinciding with periods of cool climate on Earth, are consistently linked to an 83-year cycle in the change of the rotary force driving the sun’s oscillatory motion … As the future course of this cycle and its amplitudes can be computed, it can be seen that the Gleissberg minimum around 2030 and another one around 2200 will be of the Maunder minimum type accompanied by severe cooling on Earth. This forecast should prove skillful as other long-range forecasts of climate phenomena, based on cycles in the sun’s orbital motion, have turned out correct as for instance the prediction of the last three El Niño years before the respective event.’

Dr Landscheidt concludes his introduction with the IPCC’s position on global warming, and he points to a growing list of publications showing a solar-climate connection:

PROF. NILS-AXEL MÖRNER: “THE APPROACHING GRAND SOLAR MINIMUM AND LITTLE ICE AGE CONDITIONS”

by Cap Allon, September 6, 2020 in Electroverse

Nils-Axel Mörner is the former head of the paleogeophysics and geodynamics department at Stockholm University. He retired in 2005 and since has dedicated his days to disproving the IPPC’s thermageddon nonsense while also warning of a coming Grand Solar Minimum.

Between 1997-2003, Mörner chaired an INTAS project on Geomagnetism & Climate; the project concluded that we, in the middle of the 21st century, had to be back in a new solar minimum with Little Ice Age climatic conditions.

These conclusions were quite straightforward, writes Mörner, and were included in a Special Issue of PRP: Obviously we are on our way into a new grand solar minimum. This sheds serious doubts on the issue of a continued, even accelerated, warming as proposed by the IPCC project. This quite innocent—and very true—conclusion made the publisher take the quite remarkable step to close down the entire scientific journal. This closing down gave rise to turbulence and objections within the scientific community. But it didn’t stop Mörner. He kept publishing scientific works regarding the impending GSM.

In 2015, Mörner’s “The Approaching New Grand Solar Minimum and Little Ice Age Climate Conditions” was published. It suggests that by 2030-2040 the Sun will experience a new grand solar minimum. This is evident from multiple studies of quite different characteristics, writes Mörner: the phasing of sunspot cycles, the cyclic observations of North Atlantic behavior over the past millennium, the cyclic pattern of cosmogenic radionuclides in natural terrestrial archives, the motions of the Sun with respect to the center of mass, the planetary spin-orbit coupling, the planetary conjunction history, and the general planetary-solar-terrestrial interaction.

During the previous grand solar minima—i.e. the Spörer Mini-mum (ca 1440-1460), the Maunder Minimum (ca 1687-1703) and the Dalton Minimum (ca 1809- 1821)—the climatic conditions deteriorated into Little Ice Age periods.

PROFESSOR VALENTINA ZHARKOVA: “WE ENTERED THE ‘MODERN’ GRAND SOLAR MINIMUM ON JUNE 8, 2020”

by Cap Allon, August 20, 2020 in Electroverse

A new editorial paper has landed from professor Valentina Zharkova, entitled: “Modern Grand Solar Minimum will Lead to Terrestrial Cooling“. Published on August 4, 2020, Zharkova’s latest analysis suggests that June 8, 2020 was the date on which we entered the Modern (Eddy) Grand Solar Minimum.

The opening paragraph reads:

“In this editorial I will demonstrate with newly discovered solar activity proxy-magnetic field that the Sun has entered into the modern Grand Solar Minimum (2020–2053) that will lead to a significant reduction of solar magnetic field and activity like during Maunder minimum leading to noticeable reduction of terrestrial temperature.”

Another passage states:

“Currently, the Sun has completed solar cycle 24 – the weakest cycle of the past 100+ years – and in 2020, has started cycle 25. During the periods of low solar activity, such as the modern grand solar minimum, the Sun will often be devoid of sunspots. This is what is observed now at the start of this minimum, because in 2020 the Sun has seen, in total, 115 spotless days (or 78%), meaning 2020 is on track to surpass the space-age record of 281 spotless days (or 77%) observed in 2019. However, the cycle 25 start is still slow in firing active regions and flares, so with every extra day/week/month that passes, the null in solar activity is extended marking a start of grand solar minimum.”

What are the consequences for Earth of this decrease of solar activity?

“From 1645 to 1710, the temperatures across much of the Northern Hemisphere of the Earth plunged when the Sun entered a quiet phase now called the Maunder Minimum. This likely occurred because the total solar irradiance was reduced by 0.22%,” shown below (top graph); “that led to a decrease of the average terrestrial temperature measured mainly in the Northern hemisphere in Europe by 1.0–1.5°C,” also below (bottom graph):

Astrophysicist Asserts The Globe Will Cool ~1°C During 2020-2053 Due To An Oncoming Grand Solar Minimum

by K. Richard, August 27, 2020 in NoTricksZone

During the last Grand Solar Minimum (17th century), global surface temperatures dipped to the coldest of the last 10,000 years – about 1.4°C colder than today. Dr. Zharkova, an astrophysicist, has determined another imminent drop in solar activity will lead to a 1°C cooling in the coming decades.

From 1645 to 1710, the Sun went into a quiet phase referred to as the Maunder Minimum. During this period, the “surface temperature of the Earth was reduced all over the Globe” (Zharkova, 2020). Cold summers and winters ensued, with glaciers extending onto farmland, sea ice expanding beyond the Arctic, and “frost fairs” on frozen rivers in Europe.
                                                                                                                                                       .
The coldest temperatures and most expansive ice extent (glaciers,  permafrost, sea ice) of the last 10,000 years occurred during both this period and the surrounding centuries – often referred to as the Little Ice Age (LIA) (Glazer et al., 2020,  Geirsdottir et al., 2019).
…

In a new paper, Dr. Valentina Zharkova asserts that during solar cycles 25-27, the Sun may return to a modern Maunder-like Grand Solar Minimum. This solar quiet phase is expected to substantially reduce the Earth’s solar magnetic field, which will, in turn, lead to an increase in cosmic rays extending into Earth’s atmosphere and thus an increase in high clouds reflecting the Sun’s radiation back to space.

The consequence? A reduction in global temperatures to just 0.4°C above what they were in 1710.

The role of atmospheric CO2 as a temperature-driving mechanism is not mentioned in the paper.

‘Most Of The Globe’ Could Experience ‘No Warming’ For 30 Years Due To Temperature-Driving Internal Variability

by Maher et al., July 13, 2020 in K.Richard/NoTricksZone

A new study documents the dominance of internal variability in decadal-scale global temperature changes and suggests we may experience a global cooling trend during the next 15 or even 30 years despite rising greenhouse gases.

Maher et al. (2020) acknowledge that internal variability in global surface temperature variations is “a difficult concept to communicate” because we have very few observations of its impact and so we must rely on assumptions about how the climate system might work.

Those who try to explain how internal variability affects global surface temperature often use the “Butterfly Effect” paradigm; they assume that small changes now can lead to larger changes decades from now.

Because global temperature trends are “largely determined by internal variability”, global cooling or another warming hiatus could very well be observed over the next decade. Actually, as Maher and colleagues explain, “even out to thirty years large parts of the globe (or most of the globe in MPI-GE and CMIP5) could still experience no-warming due to internal variability“.

The Next Great Extinction Event Will Not Be Global Warming – It Will Be Global Cooling

by A. MacRae, September 1, 2019 in WUWT

CATASTROPHIC GLOBAL WARMING IS A FALSE CRISIS – THE NEXT GREAT EXTINCTION WILL BE GLOBAL COOLING

Forget all those falsehoods about scary global warming, deceptions contrived by wolves to stampede the sheep. The next great extinction event will not be global warming, it will be global cooling. Future extinction events are preponderantly cold: a glacial period, medium-size asteroid strike or supervolcano. Humanity barely survived the last glacial period that ended only 11,500 years ago, the blink-of–an-eye in geologic time.

Cold, not heat, is by far the greater killer of humanity. Today, cool and cold weather kills about 20 times as many people as warm and hot weather. Excess Winter Deaths, defined as more deaths in the four winter months than equivalent non-winter months, total over two million souls per year, in both cold and warm climates. Earth is colder-than-optimum for humanity, and currently-observed moderate global warming increases life spans.

“Cold Weather Kills 20 Times As Many People As Hot Weather”

By Joseph D’Aleo and Allan MacRae, September 4, 2015

https://friendsofsciencecalgary.files.wordpress.com/2015/09/cold-weather-kills-macrae-daleo-4sept2015-final.pdf

However, Excess Winter Deaths are not the worst threats to humanity. The glacial cycle averages about 100,000 years, consisting of about 90,000 years of the glacial period, when mile-thick continental glaciers blanketed much of the Northern and Southern Hemispheres including Canada, Russia, Northern Europe and Northern USA, and about 10,000 years of interglacial, the warm period of the present. Earth is now 11,500 years into the current warm interglacial, and our planet may re-enter the glacial period at any time.

Earth about to enter 30-YEAR ‘Mini Ice Age’ with -50C temperatures in coldest regions, scientists warn

by Harry Pettit, February 2, 2020 in TheSun

Earth is bracing for a solar minimum: a quiet period in which the Sun fires less energy – or, heat – at our planet than usual.

According to Nasa, the Sun will reach its lowest activity in over 200 years in 2020.

This could cause average temperatures to drop as much as 1C in a cold spell lasting 12 months, according to Northumbria University expert Valentina Zharkova.

That might not sound like much, but a whole degree is very significant for global average temperatures.

…

…

However, Professor Zharkova warned icy spells and wet summers could persist until solar activity picks up again in 2053.

She listed recent unusual chills in Canada and Iceland as evidence of the Grand Solar Minimum (GSM) already taking hold.

“The reduction in temperature will results in cold weathers on Earth, wet and cold summers, cold and wet winters,” she told The Sun.

“We will possibly get big frosts as is happening now in Canada where they see [temperatures] of -50C.

Current Solar Cycle The Third Quietest In More Than 250 Years Of Observation

by F. Bosse & Prof. F. Vahrenholt, December 27, 2018 in ClimateChangeDispatch

The sun was much less active in November than normal, comparing all solar cycles 1-23 up to month no. 120 since the beginning of the systematic survey in 1755, the first year of solar cycle 1.

The latest observed SSN (sunspot number) was a meager 5.9 for the monthly average.

On 16 days the sun was completely “spotless.” The maximum number over the days of November was 15, which does not mean that there were 15 spots – no, the number indicates that 5 spots were observed in a maximum of 1 spot group.

So there was very low spot activity, only 20% of the average value.

92 New Papers (2018) Link Solar Forcing To Climate . . . Some Predict Solar-Induced Global Cooling By 2030!

by K. Richard, December 27, 2018 in NoTricksZone

When it comes to the Sun’s influence on climate, one conclusion is certain: there is no widespread scientific agreement as to how and to what extent solar activity and its related parameters (i.e., galactic cosmic rays, geomagnetic activity, solar wind flux) impact changes in the Earth’s temperature and precipitation.

The disagreement is so chasmic and the mechanisms are so poorly understood that scientists’ estimates of the influence of direct solar irradiance forcing between the 17th century and today can range between a negligible +0.1 W m-2 to a very robust +6 W m-2 (Egorova et al., 2018; Mazzarella and Scafetta, 2018).

“There is no consensus on the amplitude of the historical solar forcing. The estimated magnitude of the total solar irradiance difference between Maunder minimum and present time ranges from 0.1 to 6 W/m2 making uncertain the simulation of the past and future climate.”  (Egorova et al., 2018)

Why Some Scientists Say Global Warming Is Out And Global Cooling Is In

by J. Haskins & H.S. Burnett, October 23, 2018 in ClimateChangeDispatch

In a world riddled with climate-change doomsday predictions, a small but growing number of scientists are saying the highly touted climate models predicting steadily increasing global temperature due to humans’ carbon-dioxide emissions are wrong and that Earth could soon face something even direr: global cooling.

One such climate scientist is Valentina Zharkova, an astrophysicist at Northumbria University in the United Kingdom.

Zharkova and her team of researchers say that based on mathematical models of the Sun’s magnetic activity, it’s likely Earth will experience decreasing magnetic waves over a 33-year period beginning in 2021.

Zharkova is not alone.
