Net Isotopic Signature of Atmospheric CO2 Sources and Sinks: No Change since the Little Ice Age

by D. Koutsoyiannis, March 14, 2024 in MDPI – (Open Access)


Recent studies have provided evidence, based on analyses of instrumental measurements of the last seven decades, for a unidirectional, potentially causal link between temperature as the cause and carbon dioxide concentration ([CO2]) as the effect. In the most recent study, this finding was supported by analysing the carbon cycle and showing that the natural [CO2] changes due to temperature rise are far larger (by a factor > 3) than human emissions, while the latter are no larger than 4% of the total. Here, we provide additional support for these findings by examining the signatures of the stable carbon isotopes, 12 and 13. Examining isotopic data in four important observation sites, we show that the standard metric δ13C is consistent with an input isotopic signature that is stable over the entire period of observations (>40 years), i.e., not affected by increases in human CO2 emissions. In addition, proxy data covering the period after 1500 AD also show stable behaviour. These findings confirm the major role of the biosphere in the carbon cycle and a non-discernible signature of humans.

Antarctica Is Colder, Icier Now Than Any Time In 5000 Years. The Last Warm Period Was 1000 Years Ago.

by K. Richard, Apr 15, 2024 in NoTricksZone

More evidence emerges that Antarctica has undergone rapid glacier and sea ice expansion in recent centuries, in line with the long-term and recent Antarctic cooling trend.

West Antarctica’s mean annual surface temperatures cooled by more than -1.8°C (-0.93°C per decade) from 1999-2018 (Zhang et al., 2023).

Not just West Antarctica, but most of the continent also has cooled by more than 1°C in the 21st century. See, for example, the ~1°C per decade cooling trend for East Antarctica (2000 to 2018) shown in Fig. ES


According to a new study, about 6000 years ago Antarctica’s Collins Glacier’s frontline was a full 1 km southwest of its current extent. The frontline advanced to today’s extent ~5000 years ago.

“Previous studies proposed that 6000 yr BP, the frontline position of the Collins Glacier was located 1 km further south west than the present, and that the current frontline was first attained at approximately 5000 yr BP.”

The glacier then continuously retreated south of the modern extent for another 4000 years, with peak ice loss 1000 years ago (as shown in the 1000-year “Proglacial lake environment” image). In the last 1000 years this glacier has rapidly re-advanced back to the glaciated extent from 5000 years ago, which is in line with the sustained cooling trend ongoing since the Medieval Warm Period.

More New Studies Indicate There Has Been No Climate-Induced Precipitation Trend Since The 1800s

by K. Richard, Mar 11, 2024 in NoTricksZone

CO2-induced global warming was supposed to intensify the hydrological cycle and extreme precipitation. It hasn’t.

New research (Mitchell and Knapp, 2024) at a southeastern United States study site indicates there has been no significant trend in either total precipitation or intense rainfall events (IRE) over the last 250 years (1770-2020).

However, there was more IRE precipitation from 1936-1959 than from 1960-2020. In fact, the most recent 60 years has the lowest record of extreme precipitation during the study, with averages of 81.20 mm for 1770–1935, 230.45 mm for 1936–1959, but just 168.27 mm during 1960–2020.

A New 1787-2005 Temperature Reconstruction Determines The Coldest 50-Year Period Was 1940-1993

by K. Richard, Mar 4, 2024 in NoTricksZone

The warmest 50-year period in northeastern China occurred from 1844-1893.

Li et al., 2024

“Compared with single years, in general, high or low temperatures that persist for many years will more significantly affect the growth of trees [30]. When we defined years with T12-1 ≥ −10.73 °C (Mean + 1σ) and T12-1 ≤ −12.61 °C (Mean − 1σ) as extreme warm years and cold years, respectively, the reconstruction for the period of 1787–2005 contained 31 cold years and 36 warm years (Table 4). The extreme cold/warm events lasting for three or more consecutive years were discovered in 1965–1967 and 1976–1978/1791–1798, 1844–1849 and 1889–1891. An 11-year smoothing average of the reconstructed T12-1 series was performed to reveal multi-year and interdecadal variations and to detect the several prolonged cold and warm periods (Figure 5d). After smoothing with an 11-yr moving average, cold periods occurred in 1822–1830 (mean T12-1 = −12.7 °C) and 1957–1970 (mean T12-1 = −12.7 °C), while a warm period occurred in 1787–1793 (mean T12-1 = −10.4 °C) (Figure 5d). Rapid and sustained cooling was observed in the reconstructed series in the years 1790–1826 (T12-1 range −10.3 °C to −12.8 °C, mean = −12.0 °C) and 1939–1969 (T12-1 range −11.6 °C to −12.7 °C, mean = −12.1 °C), where the rates of cooling were about 0.067 °C/year and 0.035 °C/year, respectively (Figure 5d). The two cooling events may be due to the decrease in solar activity [48,49,50]. Using a 50-year time scale, the highest temperature occurring during 1787–2005 was from 1844 to 1893 (T12-1 range −12.79 °C to −9.41 °C, mean = −11.15 °C), similar results were also obtained by Zhu et al. and Jiang et al., while the lowest temperature was from 1940–1993 (T12-1 range −13.57 °C to −10.26 °C, mean = −12.13 °C) (Figure 5d) [33].”

Geologically Generated Ice Cycles And Climate-Related Phenomena

by J.E. Kamis, Feb 28, 2024 in ClimateChangeDispatch

The term “Ice Age” implies that covering Earth’s surface with ice and then melting it is a single event.

As explained below, this process is not a single event but rather a reoccurring cycle that has three distinct phases: Ice Melt/End Phase, Ice Increase/Recovery Phase, and Normal Ice Extent/Stable Phase.

Ice Melt/End Phase

Approximately every 100,000 years, the Earth’s glaciers and seas reach their maximum extent. Suddenly and within 5,000 years nearly all the ice melts. I term this the Ice Melt Phase.

So, what causes this rapid melting of the ice? It is a geologically induced pulse of heat and gas emitted from all of Earth’s geological features. A more detailed explanation of the Ice Melt Phase follows.

In 1941 Serbian mathematician Milutin Milankovitch discovered that every 100,000 years, the Earth’s orbit around the sun, tilt angle of its axis, and wobble-type movement around the axis changes. Scientists called this process a Milankovitch Cycle.

Milankovitch concluded that these astronomical changes affected Earth’s long-term climate. Others have shown that these astronomical changes also act to greatly increase the gravitational stress on Earth.

Figure 1. 50,000-mile-long interconnected network of ocean floor fault zones and ice extent during an Ice Cycle. (Image credit Wikipedia, some labeling by J. Kamis).

In my opinion, this stress activates all of Earth’s geological features, most importantly the 50,000-mile-long interconnected network of deep ocean-floor fault zones (Figure 1). These fault zones form the boundary between continents and large segments of ocean-floor rock layers.

New Study Finds No Evidence Of A CO2-Driven Warming Signal In 60 Years Of IR Flux Data

by K. Richard, Jan 11, 2024 in NoTricksZone

“The real atmosphere does not follow the GHG [greenhouse gas] GE [greenhouse effect] hypothesis of the IPCC.” – Miskolczi, 2023

CO2 increased from 310 ppm to 385 ppm (24%) during the 60 years from 1948 to 2008. Observations indicate this led to a negative radiative imbalance of -0.75 W/m². In other words, increasing CO2 delivered a net cooling effect – the opposite of what the IPCC has claimed should happen (Miskolczi, 2023).

Also, there is “no correlation with time and the strong signal of increasing atmospheric CO2 content in any time series,” which affirms “the atmospheric CO2 increase cannot be the reason for global warming.”

“The Arrhenius type greenhouse effect of the CO2 and other non-condensing GHGs is an incorrect hypothesis and the CO2 greenhouse effect based global warming hypothesis is also an artifact without any theoretical or empirical footing.”

UK Rainfall In 2023

by P. Homewood, Jan 7 ,2024 in NotaLotofPeopleKonwThat


Last year was a wet one in England & Wales, the 7th wettest on record. (The UK series has a similar result).

We routinely hear claims that the climate is wetter because a warmer atmosphere can hold more moisture, (while also being told we will get more droughts!). However the fact that we have had similarly wet years in the distant past, such as 1768, 1852, 1872, 1877, 1882, 1903 and 1960, rather demolishes that argument.

The major factor behind last year’s high rainfall was that the number of rain days was also one of the highest on record since 1931, when Met Office daily data begins. In short, annual rainfall was high because of weather, not climate.

In Climatology, Whatever Happened To Evidence-Based Science?

by J. Hellner, Nov 21, 2023 in ClimateChangeDispatch

Isn’t it time that journalists and students are taught to do research and ask questions about the climate instead of just regurgitating talking points pushing the green agenda?

We are constantly told that storms, floods, droughts, and other natural disasters are growing in frequency and intensity—so why don’t we see specific examples? [emphasis, links added]

Like the severe drought and warm period in Europe in 1540 when temperatures were 9–13 degrees above today’s averageduring the Little Ice Age?

For eleven months, there was practically no rain, and temperatures were five to seven degrees [Celsius] [9–13°F] above the normal values of the 20th century; in many places, summer temperatures must have exceeded 40°C (104°F).

Many forests in Europe went up in flames, choking smoke darkened the sun, and not a single thunderstormwas reported in the summer of 1540.

Water was already scarce in May, wells and springs dried up, mills stood still, people starved, and livestock was slaughtered. Estimates are that in 1540, half a million people died, mostly from dysentery.

Or what about the massive fires in the United States in 1871? In 1871, the Midwestern United States had a severe drought and warm weather, clearly not caused by humans and our use of natural resources.

As a result of this heat and drought, there were severe fires throughout the Midwest, including the Great Chicago Fire.

The temperature was 85 degrees on October 8, 1871. This year the high was 55 degrees, or thirty degrees cooler.

Why isn’t Chicago warmer, after 152 years, with all the cement, people, and gas vehicles and equipment if they all cause warming?

The Chicago fire alone caused $200 million in damages, which is the equivalent of over $5 billion today.

I am 70 years old, and I don’t recall serious fires during my lifetime in the Midwest.

The narrative that humans and our use of natural resources are to blame for warming temperatures, in turn creating an existential threat to our survival, is contrary to the data and facts; scientific honesty would be forming a narrative based on the evidence, instead of forcing “evidence” to fit a story.

What about the Medieval Warm Period 1,000 years ago where temperatures were similar to today? What caused that warming since it clearly wasn’t man’s use of natural resources?

North Atlantic’s marine productivity may not be declining, according to new study of older ice cores

by Universiy of Washington, Nov 13, 2023 in PhysOrg

To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. A prominent 2019 study used ice cores in Antarctica to suggest that marine productivity in the North Atlantic had declined by 10% during the industrial era, with worrying implications that the trend might continue.

But new research led by the University of Washington shows that —on which larger organisms throughout the marine ecosystem depend—may be more stable than believed in the North Atlantic. The team’s analysis of an going back 800 years shows that a more complex atmospheric process may explain the recent trends.

The study was published in the Proceedings of the National Academy of Sciences.

New Study: Antarctic Sea Ice Completed Half Its Deglacial Retreat 1000s Of Years Before CO2 Began Rising

by K. Richard, Nov 16, 2023 in NotricksZone

The timing of the dramatic Antarctic sea ice decline during the last deglaciation suggests solar forcing and sea ice retreat “instigated” century-scale climate warming and atmospheric CO2 change. This would appear to challenge the perception CO2 plays a causal role in glacial-interglacial sea ice and climate changes.

From ~21,000 to 19,500 years ago, when CO2 was thought to have been at its lowest point in the Quaternary ice age (~180 ppm), the sea ice surrounding East and West Antarctica completed 50% of its eventual deglaciation-era decline (Sadatzki et al., 2023).

“[I]ndependent lines of evidence supporting that early sea ice and surface ocean changes in the Southern Ocean initiated as early as ~19.5 ka ago (with signs of summer sea ice retreat in our reconstruction as early as ~21 ka ago) and thus (at least) about 2 ka before major deglacial changes in global ocean circulation, climate, and atmospheric CO2.”

The increase in 65°S insolation during these millennia was deemed sufficient to drive this magnitude of sea ice retreat.

“This early increase in local integrated summer insolation at 65°S, which is independent of the longitude, may have thus provided enough energy to initiate melting of the near-perennial sea ice cover in late glacial.”

Massive iceberg discharges during the last ice age had no impact on nearby Greenland, raising new questions about climate dynamics

by WUWT, Apr 24, 2023

CORVALLIS, Ore. – During the last ice age, massive icebergs periodically broke off from an ice sheet covering a large swath of North America and discharged rapidly melting ice into the North Atlantic Ocean around Greenland, triggering abrupt climate change impacts across the globe.

These sudden episodes, called Heinrich Events, occurred between 16,000 and 60,000 years ago. They altered the circulation of the world’s oceans, spurring cooling in the North Atlantic and impacting monsoon rainfall around the world.

But little was known about the events’ effect on nearby Greenland, which is thought to be very sensitive to events in the North Atlantic. A new study from Oregon State University researchers, just published in the journal Nature, provides a definitive answer.

“It turns out, nothing happened in Greenland. The temperature just stayed the same,” said the study’s lead author, Kaden Martin, a fourth-year doctoral candidate in OSU’s College of Earth, Ocean, and Atmospheric Sciences. “They had front-row seats to this action but didn’t see the show.”

Instead, the researchers found that these Heinrich events caused rapid warming in Antarctica, at the other end of the globe.

The researchers anticipated Greenland, in close proximity to the ice sheet, would have experienced some kind of cooling. To find that these Heinrich Events had no discernible impact on temperatures in Greenland is surprising and could have repercussions for scientists’ understanding of past climate dynamics, said study co-author Christo Buizert, an assistant professor in the College of Earth, Ocean, and Atmospheric Sciences.

“If anything, our findings raise more questions than answers,” said Buizert, a climate change specialist who uses ice cores from Greenland and Antarctica to reconstruct and understand the Earth’s climate history. “This really changes how we look at these massive events in the North Atlantic. It’s puzzling that far-flung Antarctica responds more strongly than nearby Greenland.”

Scientists drill and preserve ice cores to study past climate history through analysis of the dust and tiny air bubbles that have been trapped in the ice over time. Ice cores from Greenland and Antarctica provide important records of Earth’s atmospheric changes over hundreds of thousands of years.

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.

Elegantly modeling Earth’s abrupt glacial transitions

by American Institute of Physics, Mar 7, 2023 in ScienceDaily

Proxy data — indirect records of the Earth’s climate found in unlikely places like coral, pollen, trees, and sediments — show interesting oscillations approximately every 100,000 years starting about 1 million years ago. Strong changes in global ice volume, sea level, carbon dioxide concentration, and surface temperature indicate cycles of a long, slow transition to a glacial period and an abrupt switch to a warm and short interglacial period.

Milutin Milankovitch hypothesized that the timing of these cycles was controlled by the orbital parameters of the Earth, including the shape of its path around the sun and the tilt of the planet. A slightly closer orbit or more tilted planet could create a small increase in solar radiation and a feedback loop that leads to massive changes in climate. This idea suggests that there may be some predictability in the climate, a notoriously complex system.

In Chaos, by AIP Publishing, Stefano Pierini of Parthenope University of Naples proposed a new paradigm to simplify the verification of the Milankovitch hypothesis.

“The main motivation behind this study was the wish to characterize and illustrate the Milankovitch hypothesis in a simple, elegant, and intuitive way,” Pierini said.

Many models suggest that Milankovitch is correct; however, such methods are often detailed and study specific. They incorporate climate feedback loops — for example, increased ice cover reflects more radiation back into space, leading to further cooling and more ice cover — as threshold crossing rules. This means that an abrupt jump in climate only occurs once a parameter reaches a given tipping point.

Pierini’s “deterministic excitation paradigm” combines the physics concepts of relaxation oscillation and excitability to link Earth’s orbital parameters and the glacial cycles in a more generic way. The relaxation oscillation component describes how the climate slowly returns to its original glacier state after it is disturbed. At that point, the excitability piece of the model captures the external orbital changes and triggers the next glacial cycle.

By using his own threshold crossing rules and adopting a classical energy-balance model, Pierini obtained correct and robust timing of the most recent glacial cycles.`

Greenland Temperatures Rose 1°C In 1994 … Since Then They Have Been ‘Relatively Constant’

by K. Richard, Feb 27, 2023 in NoTricksZone

A warming event that spans only one year, with decades of stable temperatures before and after, would not appear to align with rapidly rising human CO2 emissions or a gradually rising atmospheric CO2 concentration.

From 1958 to 2020, as CO2 rose from 320 ppm to 410 ppm, Greenland had a warming period of 1°C that lasted one year – 1994. Over the next 26 years (1994-2020) and spanning the years 1958 to 1993, there have been “relatively constant” temperatures across Greenland (Zhang et al., 2022).

These temperature trends appear to align much better with phases of the North Atlantic Oscillation (NAO), Greenland blocking indexes (GBI), and volcanism better than they do with any anthropogenic causal agents.

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.

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.”

Good 2022 Climate News the MSM didn’t tell you

by J. Vinos, Jan 8, 2023 in WUWT

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-20th century 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.


UAH Global Temperature Update: 2022 was the 7th Warmest of 44-Year Satellite Record

by R. Spencer, Jan 3, 2023 in GlobalWarming

December of 2022 finished the year with a global tropospheric temperature anomaly of +0.05 deg. C above the 1991-2020 average, which was down from the November value of +0.17 deg. C.

The average anomaly for the year was +0.174 deg. C, making 2022 the 7th warmest year of the 44+ year global satellite record, which started in late 1978. Continuing La Nina conditions in the Pacific Ocean have helped to reduce global-average temperatures for the last two years. The 10 warmest years were:

  • #1 2016 +0.389
  • #2 2020 +0.358
  • #3 1998 +0.347
  • #4 2019 +0.304
  • #5 2017 +0.267
  • #6 2010 +0.193
  • #7 2022 +0.174
  • #8 2021 +0.138
  • #9 2015 +0.138
  • #10 2018 +0.090

The linear warming trend since January, 1979 continues at +0.13 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

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).

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.

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.”

Let’s Talk About Real Climate Cataclysms

by P. Driessen, Oct 26, 2022 in ClimateChangeDispatch

The climate crisis! Save our planet! Stop using fossil fuels! The ranting never ends.

Present data show that hurricane frequency and intensity are not increasing, and tornado activity has declined significantly since 1975.

Offer clear evidence of past, recurring major climate changes, including a widespread Little Ice Age from 1300 to 1850, a 2,400-year-old forest emerging from beneath a melting Alaskan glacier, a 5,200-year-old mummified traveler frozen on a once-nearly-ice-free Italian Alps trail – and they respond, Shut up! The climate crisis! The science is settled! Stop using fossil fuels! [bold, links added]

Fine. But take a few minutes to ponder REAL climate disasters: the Pleistocene Ice Ages.

And then ask Michael Mann, Al Gore, John Kerry, and the rest of the climate cataclysm cabal to explain exactly how carbon dioxide and a few other greenhouse gases caused those massive ice sheets to grow and melt, multiple times. Just CO2 and GHG, all by themselves. They can’t do it. The CO2-driven crisis is a fable.

Widespread glaciation began some 1,800,000 years ago in North America and Europe, and about 800,000 years earlier on other continents. There were at least four, possibly five, major glacial periods, interspersed with warm intervals (like the one we’re in now) during which the glaciers mostly melted.

That last glacial epoch is named the Wisconsinan because some of the most exemplary features are in my home state. It marks the furthest extent of glaciers southward into the United States and east and west across Canada.

Another Study Says Europe Was At Times Warmer During The Last Glacial When CO2 Levels Were 40% Lower

by K. Richard, Oct 24, 2022 in NoTricksZone

The Earth was still in ice age conditions 14,700 to 12,900 years ago, or during the “Bolling interstadial.” CO2 hovered near 230 ppm at that time, and yet “continental Europe was a few degrees warmer than present” (Toth et al., 2022).

In recent years there have been multiple studies detailing a European climate that was as warm or warmer than today during the late Pleistocene ice age.

The latest study, Toth et al., 2022, uses chironomid proxy evidence to reconstruct summer temperatures at a lake site in the Eastern Carpathians.

These authors report that “continental Europe was a few degrees warmer than present during the Bolling interstadial,” and there were slightly (0.5°C) warmer-than-today periods (e.g., ~16,300 years ago) at the study site. The warming events were both pronounced (5°C) and abrupt.

Report: The Earth Has A Changing Climate, Not A Climate Crisis

The emphasis on a false climate crisis is becoming a tragedy for modern civilization, which depends on reliable, economic, and environmentally viable energy. [bold, links added]

The windmills, solar panels, and backup batteries have none of these qualities. This falsehood is pushed by a powerful lobby which Bjorn Lomborg has called a climate industrial complex, comprising some scientists, most media, industrialists, and legislators.

It has somehow managed to convince many that CO2 in the atmosphere, a gas necessary for life on earth, one which we exhale with every breath, is an environmental poison. Multiple scientific theories and measurements show that there is no climate crisis.

Radiation forcing calculations by both skeptics and believers show that the carbon dioxide radiation forcing is about 0.3% of the incident radiation, far less than other effects on climate.

Over the period of human civilization, the temperature has oscillated between quite a few warm and cold periods, with many of the warm periods being warmer than today.

During geological times, it and the carbon dioxide levels have been all over the place with no correlation between them.

Europe wildfires: Are they linked to climate change?–NO!!!

by P. Homewood, Aug 15, 2022 in NotaLotofPeopleKnowThat

The BBC would like you to think so, with statements like these:

So far this year, the amount of land burnt by fires across the European Union is more than three times greater than what you would expect by the middle of July.

Almost 346,000 hectares (1,370 sq miles) of land have been recorded as burnt (as of 16 July), according to the European Forest Fire Information System (EFFIS).

Much of Western Europe has been hit by a record-breaking heatwave, which substantially increases the risk of fires….

“Heatwaves and droughts are exacerbated by climate change and are absolutely the defining factor in years with massive wildfire outbreaks, like the present one,” Dr Jones says….

“But we definitely see trends in fire weather risk because of climate change.

“The risk is higher in the Mediterranean region than the rest of Europe.”

Studies show increasing fire risk for central and southern regions of Europe over the past couple of decades.

Yet tucked away in the same article is this graph which proves all of these have no basis in fact:
