Hunga Tonga volcano: impact on record warming

by J. Vinos, July 9, 2024 in WUWT

1. Off-scale warming

Since the planet has been warming for 200 years, and our global records are even more recent, every few years a new warmest year in history is recorded. Despite all the publicity given each time it happens, it would really be news if it didn’t happen, as it did between 1998 and 2014, a period popularly known as the pause.

Figure 1. Berkeley Earth temperature anomaly

Since 1980, 13 years have broken the temperature record. So, what is so special about the 2023 record and the expected 2024 record? For starters, 2023 broke the record by the largest margin in records, 0.17°C. This may not sound like much, but if all records were by this margin, we would go from +1.5°C to +2°C in just 10 years, and reach +3°C 20 years later.

Peer reviewed skepticism

by D. Wojick, July 9, 2024 in WUWT

A fine skeptical journal article waded through green pal review. Wonder of wonders!

The journal is the American Journal of Economics and Sociology. The article title is perfectly clear: “Carbon dioxide and a warming climate are not problems”.

See https://onlinelibrary.wiley.com/doi/10.1111/ajes.12579

But it is an “Early View Online Version of Record before inclusion in an issue” so get it before it gets too hot for the Journal. I understand it is very popular so the green screams are deafening.

Alas it is paywalled but the lengthy free Abstract is as clear as the title. Here is the conclusion:

“Observations show no increase in damage or any danger to humanity today due to extreme weather or global warming (Crok & May,  2023, pp. 140–161; Scafetta,  2024). Climate change mitigation, according to AR6, means curtailing the use of fossil fuels, even though fossil fuels are still abundant and inexpensive. Since the current climate is arguably better than the pre-industrial climate and we have observed no increase in extreme weather or climate mortality, we conclude that we can plan to adapt to any future changes. Until a danger is identified, there is no need to eliminate fossil fuel use.”

The authors are Andy May and Marcel Crok and as the first parenthetical reference above indicates they are building on prior work. Their 53 References are not paywalled and quite interesting. Continuer la lecture de Peer reviewed skepticism →

Media Reports Earth’s ‘1.5C Temperature limit’ was ‘breached for 12 months in a row’ – Nothing Bad Happened

by A. Watts, July 10, 2024 in WUWT

Originally posted at ClimateREALISM

Recently, several media outlets claimed that June 2024 was the hottest June on record globally and that it topped off a string of 12 or 13 warmer than normal months, which they blamed on human-induced climate change. Each of the news stories made false claims of reaching climate tipping points, extreme weather events, and that the extended streak of hot temperatures proved a “climate crisis” was at hand.

Here are some of the headlines: Temperatures 1.5C above pre-industrial era average for 12 months, data shows (The Guardian,) June sizzled to a 13th straight monthly heat record, but July might break string (National Public Radio,) and World in line for hottest year as 1.5C limit breached for 12 months in a row (Financial Times.)

That ongoing 1.5C temperature limit scare-story has people around the world rattled. For example, this infographic from The Asia-Pacific branch of the International Union of Food workers (IUF) says (bold author’s):

Global warming caused by human activities reached approximately 1°C over the past 170 years, increasing at 0.2°C per decade. Scientists warn that an average rise of more than 1.5°C in the surface temperature of the earth compared to pre-industrial levels will be catastrophic for the environment and human health.

But despite 12 months of the globe being above the so-called temperature limit, nothing bad happened on a global scale. Claims of climate catastrophe once we passed the so-called 1.5C temperature limit, never happened. The limit was nothing more than a political talking point from the 2015 Paris Climate Conference, as described in this Associated Press article: The magic 1.5: What’s behind climate talks’ key elusive goal. The AP wrote, “in a way both the ‘1.5 and 2 degree C thresholds are somewhat arbitrary,’ Stanford University climate scientist Rob Jackson said in an email. ‘Every tenth of a degree matters!’”

Now, despite surpassing that arbitrary limit, the “crisis” progressive politicians and alarmists in the mainstream media have been warning about failed to materialize.

First let’s check the global temperature. The source of all these news stories comes from a recent press release by Copernicus, part of the European Commission. A graph by Copernicus, seen in Figure 1 below, illustrates the “limit” and the 12-month temperature peak:

High-frequency climate forcing causes prolonged cold periods in the Holocene.

by E. van Dijk et al., May 08 2024, in Nature (OPEN ACCESS)

Abstract

Understanding climate variability across interannual to centennial timescales is critical, as it encompasses the natural range of climate fluctuations that early human agricultural societies had to adapt to. Deviations from the long-term mean climate are often associated with both societal collapse and periods of prosperity and expansion. Here, we show that contrary to what global paleoproxy reconstructions suggest, the mid to late-Holocene was not a period of climate stability. We use mid- to late-Holocene Earth System Model simulations, forced by state-of-the-art reconstructions of external climate forcing to show that eleven long-lasting cold periods occurred in the Northern Hemisphere during the past 8000 years. These periods correlate with enhanced volcanic activity, where the clustering of volcanic eruptions induced a prolonged cooling effect through gradual ocean-sea ice feedback. These findings challenge the prevailing notion of the Holocene as a period characterized by climate stability, as portrayed in multi-proxy climate reconstructions. Instead, our simulations provide an improved representation of amplitude and timing of temperature variations on sub-centennial timescales.

Climate Activists Are Wrong About Which Energy Source Reduces Air Pollution

by S. Graham, June 20, 2024 in WUWT

oday’s media are filled with concerns about air pollution. But few people know which energy source has produced the greatest modern reduction in air pollution. The answer isn’t wind or solar energy.

During the 1950s, my grandfather had a coal furnace in his basement, like many homes in Chicago. Five days after a winter snowfall, the snow was covered with a visible black film of dust from coal furnaces. Our younger generation does not know the original reason for “spring cleaning.” Every spring, homeowners would wash their inside walls to remove coal dust.

It was the rising use of gas fuel, primarily natural gas along with propane, that produced the greatest reduction in air pollution in the United States and across the world. Gas furnaces and stoves have replaced wood in businesses and homes in developed nations. And natural gas power plants have replaced coal-fired plants to generate electricity, with gas becoming the leading fuel for industry.

Natural gas and propane are clean-burning fuels that emit no harmful pollutants when burned. When gas heating is substituted for coal or wood heating, indoor particulate pollution is reduced by 1,000 times.

Today, 70% of US homes use natural gas or propane, a percentage that has been rising for decades. Gas fuels have also become the leading heating and cooking source in Europe, providing 83% of heat energy in the Netherlands and 78% in the United Kingdom. But there are still 70 million wood stoves in Europe.

The World Health Organization estimates that 2 billion people in developing nations still cook using open fires or inefficient stoves fueled by kerosene, biomass (wood, charcoal, animal dung, or crop waste), and coal. These fuels generate harmful indoor air pollution. Indoor air pollution is estimated to cause more than 3 million deaths annually in poor nations. Emerging nations need gas fuels to boost health and well-being.

Has the Sun’s true role in global warming been miscalculated?

by CeresTeam, Oct 2023 in CeresScience

A new international study published in the scientific peer-reviewed journal, Research in Astronomy and Astrophysics, by 20 climate researchers from 12 countries suggests that the UN’s Intergovernmental Panel on Climate Change (IPCC) might have substantially underestimated the role of the Sun in global warming.

The article began as a response to a 2022 commentary on an extensive review of the causes of climate change published in 2021. The original review (Connolly and colleagues, 2021) had suggested that the IPCC reports had inadequately accounted for two major scientific concerns when they were evaluating the causes of global warming since the 1850s:

  1. The global temperature estimates used in the IPCC reports are contaminated by urban warming biases.

  2. The estimates of solar activity changes since the 1850s considered by the IPCC substantially downplayed a possible large role for the Sun.

On this basis, the 2021 review had concluded that it was not scientifically valid for the IPCC to rule out the possibility that global warming might be mostly natural.

The findings of that 2021 review were disputed in a 2022 article by two climate researchers (Dr. Mark Richardson and Dr. Rasmus Benestad) for two main reasons:

  1. Richardson and Benestad (2022) argued that the mathematical techniques used by Connolly and colleagues (2021) were inappropriate and that a different set of mathematical techniques should have been used instead.

  2. They also argued that many of the solar activity records considered by Connolly and colleagues (2021) were not up-to-date.

They suggested that these were the reasons why Connolly and colleagues (2021) had come to a different conclusion from the IPCC.

This new 2023 article by the authors of the 2021 review, has addressed both of these concerns and shown even more compelling evidence that the IPCC’s statements on the causes of global warming since 1850 are scientifically premature and may need to be revisited.

The authors showed that the urban component of the IPCC’s global temperature data shows a strong warming bias relative to the 98% of the planet that is unaffected by urbanization. However, they also showed that urbanized data represented most of the weather station records used.

 

While the IPCC only considered one estimate of solar activity for their most recent (2021) evaluation of the causes of global warming, Connolly and colleagues compiled and updated 27 different estimates that were used by the scientific community.

Several of these different solar activity estimates suggest that most of the warming observed outside urban areas (in rural areas, oceans, and glaciers) could be explained in terms of the Sun. Some estimates suggest that global warming is a mixture of human and natural factors. Other estimates agreed with the IPCC’s findings.

For this reason, the authors concluded that the scientific community is not yet in a position to establish whether the global warming since the 1850s is mostly human-caused, mostly natural or some combination of both.

Olympics 2024: how extreme weather could impact Paris games

by S. King, , June 18 2024, BBC

The summer Olympics and Paralympic games in Paris are just over a month away and there is concern about the potential effects of extreme heat.

Some parts of Europe have already registered temperatures over 40C and it is not unreasonable to suggest that elsewhere in Europe will experience heatwaves in the coming months.

In a report published on Tuesday, Lord Coe, President of World Athletics, says “climate change should increasingly be viewed as an existential threat to sport”.

Intense heat could affect the events, competitors, spectators and officials.

Changing climate of Paris

We don’t know what the forecast will be for Paris during the Olympic period, but Meteo France – the national weather service – has said that summer is likely to be warmer than average.

France has experienced deadly summer heatwaves in the past.

The highest recorded temperature in Paris is 42.6C set at the end of July 2019.

And more recently in 2022, during the Olympic period, a lengthy heatwave saw maximum temperatures reach 36C.

That year the National Institute of Statistics and Economic Studies in France estimated heat-related deaths of 11,000 throughout the summer.

At the last Olympics in Tokyo in 2021, extreme heat made it “torturous” for athletes and volunteers, according to local meteorologists.

It was the hottest Olympic Games on record with sweltering temperatures of 34C and humidity of 70%, which would have made it feel like 47C.

Tennis player Daniel Medvedev spoke of “dying on court” during the heat of a match.

Other competitors vomited and fainted on the finish line because of the high temperatures.

Climate Propaganda Cabals Ramp Up the Heat for Summer

by K. Hansen, June 18, 2024 in WUWT

Covering Climate Now [CCNow], the Columbia University-based climate propaganda outfit, which claims the ability to reach over 2 billion people worldwide with its ready-to-use, ready-to-share and content-directed climate alarm stories, is ramping up and issuing directives to climate journalists around the world.

Here are the main points that they insist that journalist around the world make in each and every story about Summer.

“Reporting Guidance: 2024’s Extreme Heat

Climate change is making extreme heat more frequent and more severe. Here are resources, sample copy, and tips to help you meet the moment.”

Now, I am a climate journalist myself and I admit that I am not entirely sure exactly what they mean by “tips to help you meet the moment”, nonetheless, I will share those tips with readers here.  Why?  So that when you see them repeated in your local newspapers, hear them on the radio, or watch some TV weatherman rattle them off, you’ll know the true source of the exaggerated statements and general misinformation.

There’s a summer heat wave going on, which gives journalists the opportunity to fill up their stories with climate change boilerplate. [emphasis, links added]

It no longer matters whether any of it is true. Just the opposite, in fact. If you point out the truth, you’re accused of being a denier.

Sure, the data doesn’t show an increase in the number or intensity of hurricanes or tornadoes or wildfires. Yet every time one or the other strikes, the press robotically connects that event to “climate change.”

Every tornado season, we hear about how climate change is making them more frequent and more deadly. Except the facts don’t support the narrative.

The world is using more oil, coal and gas than ever before and will use more. Net Zero is dead

by P. Homewood, June 14, NotaLotofPeopleKnowThat

A recent flurry of forecasts offers us a range of different views on what’s happening to the global demand for, and use of, crude oil. One thing seems to be clear, however: the chances of net zero carbon emissions in the near term – ie, by 2050 – are basically zero.

The year so far has been a bit of a rollercoaster ride in this realm of uncertainty, with projections and forecasts more volatile than the market itself. Crude prices have remained relatively strong despite various occurrences across Europe and the Middle East that would have resulted in major upsets in decades past.

One major point of consensus related to global oil demand growth is the expectation that it will continue to be robust, driven by a combination of factors including economic recovery, increased travel, and surging industrial activity in non-OECD nations.

The only major body not seeing continued, massive growth is the International Energy Agency (IEA), which revised its numbers this week to predict that crude demand will rise by just 1 million barrels per day (bpd) next year and will (at last!) peak “towards the end of this decade” at 106 million bpd, up from 102 million at the moment. The IEA expects this growth to be led by non-OECD countries, particularly China and India. The IEA and others have highlighted the importance of these regions in driving global oil demand.

The IEA, which is funded by 31 industrialized nations through a dues structure, says that it believes growth in demand from India, China and elsewhere will be gradually outweighed by the expected rollout of electric vehicles and other green technologies. However, one should note that the agency has been shifting for a long time from being an analytical organisation to being essentially a green campaigning one, and its forecasts nowadays are as much attempts to influence markets as to genuinely predict them.

In contrast to the IEA, the US Energy Information Administration (EIA) raised its 2024 global oil demand growth forecast to 1.1 million barrels per day, up from its previous estimate of 900,000 bpd. This revision is based on expectations for travel and tourism in the second half of the year. EIA projects even stronger demand growth for 2025 of 1.5 mbpd, again clashing with the IEA which sees just 1 mbpd that year, with non-OECD countries accounting for most of the growth. The US federal agency also raised its projection for crude prices to rise to an average of $87/barrel in Q4 2024 based on the rising demand.

Surveys Show Vast Bulk of Antarctica Is Stable or Growing

by  H.S. Sterling, June. 16, 2024 in WUWT

We hear a lot in the mainstream media about massive ice loss in Antarctica and how it may radically increase sea level rise. The West Antarctic ice sheet and ice on the Antarctic peninsula are in decline, with some massive glaciers threatening to break off; however, conditions there are not the same as for the vast bulk of the continent. First, the subsurface geothermal/volcanic activity that is driving much of the melting in West Antarctica is not affecting the vast bulk of the continent. And the shifting ocean oscillations, which affect the continent’s climate as a whole, have a much greater, more direct impact on the Antarctic peninsula, the northern-most part of the continent, a relatively narrow spit of land surrounded by oceans and beset be clashing currents.

The conditions of the sea ice around Antarctica don’t matter in the sea level equation. Sea ice changes dramatically each season, waxing and waning with the seasons and the currents. For the limited period for which we have consistent measurements, Antarctica’s sea ice has set new records for extent and for low levels during the most recent period of climate change. Neither, however, impact sea levels since floating ice doesn’t displace water.

NASA reported in 2015 that because East Antarctica, which makes up the bulk of the continent, was adding ice and snow, Antarctica as whole may, in fact, be gaining ice on net, implying it could be modestly taking away from sea level rise rather than adding to it. At least from 1992 to 2015, when the report was published.

IPCC Refuses Repeated Calls for Dialogue with Critical Scientists

by A. Blok, Apr 29, 2024 in Liberum

The Intergovernmental Panel on Climate Change (IPCC) ignores crucial peer-reviewed literature and cherry-picks evidence to promote doom scenarios on climate change. These are just some of the findings of Climate Intelligence (Clintel) founder emeritus professor Guus Berkhout (84) after critically analyzing IPCC’s scientific reports. “They refuse my request for an honest and open debate. The result is a very one-sided, fear-mongering story.”

By Arthur Blok
In 1925, a group of internationally renowned scientists gathered in Haarlem at the invitation of the Royal Dutch Society of Sciences (KHMV), the Netherlands’ oldest scientific society. The scientists celebrated the golden doctorate of Dutch physicist Hendrik Lorentz, who shared the 1902 Nobel Prize in Physics with Pieter Zeeman.

Among its participants were Albert Einstein, Paul Ehrenfest, and Madame Curie, to name a few. Until today, the society holds annual meetings to promote science in its broadest sense, inviting the world’s most prominent to discuss, interpret, and share their findings. Since its inception in 1752, the KHMV has advocated that sharing knowledge is one of science’s core principles.

Berkhout and his Clintel—a global climate change and policy foundation—are loyal to that principle. Since 2019, they have taken the lead in speaking against the discourse of climate fear spread by politicians, movements, and the mainstream media. Berkhout even went as far as calling the so-called man-made climate emergency a hoax.

The Dutch emeritus professor has now targeted the IPCC and its members. The IPCC is a United Nations (UN) intergovernmental body that aims to advance scientific knowledge about climate change caused by human activities. Based on the research results, governmental policies should be designed and executed to stop climate change.

In the past year, Berkhout sent three personal letters expressing his worries to the IPCC chair, Professor Dr James Skea, but to no avail.

“I received only a small note from their secretariat saying they do not have the mandate to accept my proposal for cooperation. While the request in my first letter was strictly a request for debate and interaction, it was quite a remarkable reaction for a scientific panel”, he said.

Climate models can’t explain 2023’s huge heat anomaly — we could be in uncharted territory

by G. Schmidt, Mar 19, 2024 in Nature

Taking into account all known factors, the planet warmed 0.2 °C more last year than climate scientists expected. More and better data are urgently needed.

When I took over as the director of NASA’s Goddard Institute for Space Studies, I inherited a project that tracks temperature changes since 1880. Using this trove of data, I’ve made climate predictions at the start of every year since 2016. It’s humbling, and a bit worrying, to admit that no year has confounded climate scientists’ predictive capabilities more than 2023 has.

For the past nine months, mean land and sea surface temperatures have overshot previous records each month by up to 0.2 °C — a huge margin at the planetary scale. A general warming trend is expected because of rising greenhouse-gas emissions, but this sudden heat spike greatly exceeds predictions made by statistical climate models that rely on past observations. Many reasons for this discrepancy have been proposed but, as yet, no combination of them has been able to reconcile our theories with what has happened.

For a start, prevalent global climate conditions one year ago would have suggested that a spell of record-setting warmth was unlikely. Early last year, the tropical Pacific Ocean was coming out of a three-year period of La Niña, a climate phenomenon associated with the relative cooling of the central and eastern Pacific Ocean. Drawing on precedents when similar conditions prevailed at the beginning of a year, several climate scientists, including me, put the odds of 2023 turning out to be a record warm year at just one in five.

Significant West Antarctic Cooling in the Past Two Decades Driven by Tropical Pacific Forcing

by X. Zhang et al., 2023, Apt 30, 2024  in BullAmerMeterologicalSoc

Abstract

During the second half of the twentieth century, the West Antarctic Ice Sheet (WAIS) has undergone significant warming at more than twice the global mean and thus is regarded as one of the most rapidly warming regions on Earth. However, a reversal of this trend was observed in the 1990s, resulting in regional cooling. In particular, during 1999–2018, the observed annual average surface air temperature had decreased at a statistically significant rate, with the strongest cooling in austral spring. The spring cooling correlates significantly with the second leading modes (EOF2) derived from empirical orthogonal function (EOF) analysis on the sea level pressure over Antarctica during 1999–2018, associated with the negative phase of the interdecadal Pacific oscillation with an average of cooling of central and eastern tropical Pacific surface sea temperature (SST) anomalies. The EOF2 results in the enhanced cold southerly winds on the continental WAIS through the cyclonic conditions over the Amundsen Sea region and a blocking high in the Drake Passage and northern Antarctic Peninsula, causing the WAIS cooling trend.

The Earth Before Hydrocarbons

by B. Stewart, Apr 26, 2024 in ClimateChangeDispatch

prehistoric earth life plants

The Earth is approximately 4.5 billion years old. During the first four billion years, there were no hydrocarbons beneath the surface: no coal, no oil, no natural gas.

All the carbon atoms on Earth are in plants, animals, or the atmosphere. Yet the oceans did not boil. The Earth was not too hot for life. If it had been we would not be here.

The first lifeforms arose early in Earth’s existence.

The earliest fossils of microbes themselves, rather than just their byproducts, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago. (Wacey, D., Kilburn, M. R., Saunders, M., Cliff, J., and Brasier, M. D. (2011). Microfossils of sulfur-metabolizing cells in 3.4-billion-year-old rocks of Western Australia. Nature Geoscience, 4, 698-702. http://dx.doi.org/10.1038/ngeo1238.)

Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago.

However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible). (Hypotheses about the origins of life, Khan Academy.)

Organisms evolved that employ the process of photosynthesis. This plant life continues to consume carbon dioxide (CO2) and produce oxygen.

After a billion years or so, an atmosphere resembling that of the present day began to take shape. Earth’s present atmosphere is composed as follows:

It is important to note that in the above circle graphs, nitrogen, oxygen, and argon compose 99.964% of our atmosphere. The amount of CO2 is 0.04%.

El Nino Fueled ‘Unprecedented’ West African Heatwave, Not Climate Change

by L. Lueken, Apr 19, 2024 in ClimateChangeDispatch

Multiple media outlets, including the BBC and Reuters, claim that a recent West African heatwave would be “impossible” without global warming. This claim is misleading and not supported by real-world data. [emphasis, links added]

The study cited in both articles is merely an attribution modeling study, which is not proof of the influence of climate change.

In their article on a recent heatwave in West Africa and the Sahel, Reuters reports“[t]emperatures soared so high in Mali and Burkina Faso they equated to a once in 200-year event, according to the report on the Sahel region by World Weather Attribution (WWA).”

Reuters continues: “The severity of the heatwave led WWA’s team of climate scientists to conduct a rapid analysis, which concluded the temperatures would not have been reached if industry had not warmed the planet by burning fossil fuels and other activities.”

One of World Weather Attribution’s statisticians even went so far as to say that heatwaves of that intensity wouldn’t happen at all in the region in a “preindustrial climate.”

This claim is utterly unfounded, as those parts of Africa are known for being at least semi-arid, subtropical, and prone to drought and heatwaves.

While temperature records are not very lengthy or complete for many parts of Africa, April is known to be the hottest month of the year for Burkina Faso in particular, and many parts of the Sahel region in general, where temperature maximums on average are above 40°C – which is what the recent heatwave brought, meaning there is no justification for claiming the recent heatwave is historically unprecedented.

Climate Realism has frequently noted that WWA’s “rapid attribution” studies are more in the realm of fantasy than fact, as they depend on virtual models of climate conditions that do not actually exist in real life.

The model of the climate that an event like the recent Sahel heatwave is compared to represents how scientists guess things would have been had it not been for the burning of fossil fuels.

Nutritive Value of Plants Growing in Enhanced CO2 Concentrations (eCO2)

by CO2 Coalition, Apr 22, 2024

We are pleased to announce the publication of our latest research report Nutritive Value of Plants Growing in Enhanced CO2 Concentrations (eCO2).

Despite many years of claims that increasing concentrations of CO2 are an “existential threat” to life on Earth, one cannot identify any harm that has been done. In fact, the only clear result of increasing CO2 has been an overall greening of the Earth and increasing productivity of agricultural and forest crops.

The evidence for greening of the Earth from eCO2 is now too obvious to deny. In recent years, some researchers have claimed that that nutritional values are negatively affected by elevated CO2 concentrations. Media promoters of climate alarmism have seized on these results to further demonize CO2.

In this paper we explain why the nutritional value of our more abundant crops can and will remain high as atmospheric CO2 concentrations increase toward values more representative of those existing throughout most of Earth’s history.

While this is a somewhat technical report, it is a valuable tool for you to put in your quiver to use the next time you see increased CO2 being linked to declining nutrition.

Climate Change Is Normal and Natural, and Can’t Be Controlled

by F.B. Soepyan, Apr 22, 2024 in WUWT

NASA claimed that “Earth is warming at an unprecedented rate” and “human activity is the principal cause.” Others proposed spending trillions of dollars to control the climate. But are we humans responsible for climate change? And what can we do about it?

“The climate of planet Earth has never stopped changing since the Earth’s genesis, sometimes relatively rapidly, sometimes very slowly, but always surely,” says Patrick Moore in Fake Invisible Catastrophes and Threats of Doom. “Hoping for a ‘perfect stable climate’ is as futile as hoping the weather will be the same and pleasant, every day of the year, forever.”

In other words, climate change is normal and natural, and you can forget about controlling it.

For instance, a major influence of weather and climate are solar cycles driven by the Sun’s magnetic field over periods of eight to 14 years. They release varying amounts of energy and produce dark sunspots on the Sun’s surface. The effects of solar cycles on Earth vary, with some regions warming more than 1°C and others cooling.

Climatic changes occur as a result of variations in the interaction of solar energy with Earth’s ozone layer, which influences ozone levels and stratospheric temperatures. These, in turn, affect the speed of west-to-east wind flows and the stability of the polar vortex. Whether the polar vortex remains stable and close to the Arctic or dips southward determines whether winters in the mid-latitudes of the Northern Hemisphere are severe or mild.

In addition to solar cycles, there are three Milankovitch cycles that range in length from 26,000 to 100,000 years. They include the eccentricity, or shape, of Earth’s elliptical orbit around the Sun. Small fluctuations in the orbit’s shape influence the length of seasons. For example, when the orbit is more like an oval than a circle, Northern Hemisphere summers are longer than winters and springs are longer than autumns.

Climate Change Is Normal and Natural, and Can’t Be Controlled

by F.B. Soepyan, Apr 19, 2024 in CO2Coalition

NASA claimed that “Earth is warming at an unprecedented rate” and “human activity is the principal cause.” Others proposed spending trillions of dollars to control the climate. But are we humans responsible for climate change? And what can we do about it?

“The climate of planet Earth has never stopped changing since the Earth’s genesis, sometimes relatively rapidly, sometimes very slowly, but always surely,” says Patrick Moore in Fake Invisible Catastrophes and Threats of Doom. “Hoping for a ‘perfect stable climate’ is as futile as hoping the weather will be the same and pleasant, every day of the year, forever.”

In other words, climate change is normal and natural, and you can forget about controlling it.

For instance, a major influence of weather and climate are solar cycles driven by the Sun’s magnetic field over periods of eight to 14 years. They release varying amounts of energy and produce dark sunspots on the Sun’s surface. The effects of solar cycles on Earth vary, with some regions warming more than 1°C and others cooling.

Climatic changes occur as a result of variations in the interaction of solar energy with Earth’s ozone layer, which influences ozone levels and stratospheric temperatures. These, in turn, affect the speed of west-to-east wind flows and the stability of the polar vortex. Whether the polar vortex remains stable and close to the Arctic or dips southward determines whether winters in the mid-latitudes of the Northern Hemisphere are severe or mild.

In addition to solar cycles, there are three Milankovitch cycles that range in length from 26,000 to 100,000 years. They include the eccentricity, or shape, of Earth’s elliptical orbit around the Sun. Small fluctuations in the orbit’s shape influence the length of seasons. For example, when the orbit is more like an oval than a circle, Northern Hemisphere summers are longer than winters and springs are longer than autumns.
