“The big-tech censors are at it again: the CO2 Coalition’s Executive Director Gregory Wrightstone has been permanently banned from LinkedIn. What did Wrightstone do to earn the banishment? His ‘crime’ consisted of posting charts from peer reviewed research supported by official sources demonstrating that current global average CO2 levels are well within the natural range of concentrations throughout the Earth’s history. LinkedIn’s moderators sent Wrightstone an email informing him that his violations have been sonumerous and/or so severe that they couldn’t allow him to continue to use the platform.”

During late 2021, the Hunga Tonga-Hunga Ha’apai submarine volcano erupted creating a new island which erupted sub-aerially on 15thJanuary, 2022 sending a plume 58 km above sea level penetrating the mesosphere. The study of observation records including satellite data has revealed warming of the ocean-surface layer followed by atmospheric cooling caused by the release of geothermal heat and volcanic materials entering the atmosphere respectively. Environmental factors influencing weather include the development of a relatively ‘short’ life-span South Pacific Blob; the transfer of large quantities of water vapour from the ocean into the atmosphere; the low-pressure condition on the ocean surface; the formation of clouds; the reduction of solar radiation caused by volcanic materials in the atmosphere; the strengthening of trade winds; the meandering of jet streams; the development of atmospheric rivers, the additional cooling effect of torrential rainfall, and, the switch to La Niña conditions. The record rainfall in eastern Australia and New Zealand and Tropical Cyclone Dovi occurring in February 2022 were both outcomes of atmospheric cooling following the sub-aerial eruption.
The moon sustained twice as many impacts as can be seen on its surface, scientists find.
Around 4.4 billion years ago, the early solar system resembled a game of space rock dodgeball, as massive asteroids and comets, and, later, smaller rocks and galactic debris pummeled the moon and other infant terrestrial bodies. This period ended around 3.8 billion years ago. On the moon, this tumultuous time left behind a heavily cratered face, and a cracked and porous crust.
Now MIT scientists have found that the porosity of the moon’s crust, reaching well beneath the surface, can reveal a great deal about the moon’s history of bombardment.
In a study appearing in Nature Geoscience, the team has shown through simulations that, early on in the bombardment period, the moon was highly porous — almost one-third as porous as pumice. This high porosity was likely a result of early, massive impacts that shattered much of the crust.
Scientists have assumed that a continuous onslaught of impacts would slowly build up porosity. But surprisingly, the team found that nearly all the moon’s porosity formed rapidly with these massive imapcts, and that the continued onslaught by smaller impactors actually compacted its surface. These later, smaller impacts acted instead to squeeze and compact some of the moon’s existing cracks and faults.
From their simulations, the researchers also estimated that the moon experienced double the number of impacts as can be seen on the surface. This estimate is lower than what others have assumed.
“Previous estimates put that number much higher, as many as 10 times the impacts as we see on the surface, and we’re predicting there were fewer impacts,” says study co-author Jason Soderblom, a research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “That matters because that limits the total material that impactors like asteroids and comets brought to the moon and terrestrial bodies, and gives constraints on the formation and evolution of planets throughout the solar system.
There is a glaring problem in the energy transition that not many people are acknowledging.
It is being built on the back of finite resources, and the mining industry is already warning that there aren’t enough metals for all the batteries the transition will require.
Because of the short supply, prices are on the rise, as are prices across commodity sectors.
The energy transition has been set by politicians as the only way forward for human civilization. Not every country on the planet is on board with it, but those that are have the loudest voices. And even amid the fossil fuel crunch that is beginning to cripple economies, the transition remains a goal. It is no secret that the transition—at the scale its architects and most fervent proponents envisage it—would require massive amounts of metals and minerals. What does not get talked about so much is that most of these metals and minerals are already in short supply. And this is only the start of the transition problems.
Mining industry executives have been warning that there is not enough copper, lithium, cobalt, or nickel for all the EV batteries that the transition would require. And they have not been the only ones, either. Even so, the European Union just this month went ahead and effectively banned the sales of cars with internal combustion engines from 2035.
“Rare earth materials are fundamental building blocks and their applications are very wide across modern life,” a senior VP at MP Minerals, a rare-earth miner, told Fortune this month. He added that “one third of the demand in 2035 is not projected to be satisfied based on investments that are happening now.”
Because of the short supply, prices are on the rise, as are prices across commodity sectors. According to a calculation by Barron’s, the price of a basket of EV battery metals that the service tracks has jumped by 50 percent over the past year as a result of various factors, including Western sanctions against Russia, which is a major supplier of such metals to Europe.
A new study (Gupta et al., 2022) indicates that from 2000-2019 73% of the 15 sites considered have been cooling and 67% have experienced a lengthening of sea ice duration.
Canada’s Hudson Bay extends into the Arctic Ocean and its coasts are teeming with polar bears.
Scientists report 11 of 15 Hudson Bay sites have been cooling since 2000. The average cooling for these 11 sites is -0.34°C per decade.
Germany is going backwards. Last month, Robert Habeck – German vice-chancellor and co-leader of the Green Party – announced that Germany will significantly increase its use of coal power, in order to wean itself off Russian gas. The energy situation is critical, says Habeck – not least as Russia has cut the amount of gas it supplies to Germany via the Nord Stream 1 pipeline by 60 per cent.
So much for Germany’s much-vaunted Energiewende, or clean-energy transition. For years, the transition to renewable energy has been sold as an expression of modernity – of a new technologically advanced and environmentally sustainable Germany. It is one of the few policies that politicians have shown any enthusiasm for in recent years. Now that the Energiewende is going into reverse – with a Green Party minister leading the charge back to one of the most polluting forms of energy – its shortcomings are impossible to ignore.
Of course, the plan to fire up the coal-fired power plants has been presented as an ‘emergency’ measure, in response to the war in Ukraine. As recently as December, the German government was promising to accelerate the phase-out of coal power. Instead of eliminating coal by 2038, as Angela Merkel had planned, the new government aims to end the use of coal by 2030. On the world stage, the German government has lobbied heavily for a global phasing-out of coal to fight climate change. Back in November, the government signed a new climate declaration – the ‘Global Coal to Clean Power’ Transition Statement’.

Germany’s irrational green politics should be a warning to the world.
European Parliament backs listing nuclear energy, gas as ‘green’
The push to label natural gas and nuclear energy as “green” in order to lure in more private investors was met with heavy resistance. But EU lawmakers ultimately gave it the green light.
The European Parliament on Wednesday voted in favor of a proposal regarding labeling natural gas and nuclear power plants as climate-friendly investments.
The European Commission released the proposal, formally called the EU taxonomy, in December as a list of economic activities that investors can label and market as green in the EU.
A motion to block the proposal received 278 votes in favor and 328 against, while 33 lawmakers abstained.
Unless 20 of the EU’s 27 member states oppose the proposal, it will be passed into law.

In a refreshingly honest article in the Logan Daily News, author Bud Simpson cites data from research showing deaths from non-optimal temperatures are declining amid climate change.
Simpson is right and he and the Logan Daily News are to be congratulated for discussing this important truth about climate change. [bold, links added]
In a Logan Daily News article, titled “My last global warming column?”, Simpson describes how after examining the facts over time, he went from being a firm believer that human activities were causing dangerous climate change to realizing no climate catastrophe is in the offing.
“Carbon dioxide was, and is, bandied about as if it were the biggest demon on the face of the earth,” writes Simpson. “In truth, it is one of the most valuable of gases and contributes hugely to a better life for us earthlings. … Proponents of this group even tried to get carbon dioxide labeled as a toxic gas! If that were true, we’d all be dead by now. And without any warming.”
Among the research Simpson discovered that convinced him climate change was not, in fact, threatening human survival was a study published in the prominent peer-reviewed journal, The Lancet, which firmly established:
“…that worldwide, cold kills about 17 times more people than heat does. A group of 22 scientists studied over 74 million deaths in the U.S., China, Brazil, and ten other countries. The findings showed that cold caused 7.29 percent of the deaths while heat caused 0.42 percent.”
These much warmer Greenland temperatures imply that the elevation of the ice sheet was 400 meters lower than it is today from about 6,000 to 10,000 years ago.
Scientists (Westhoff et al., 2022) report that the two largest Greenland melt events in the last few hundred years occurred in 2012 and in 1889 CE – when atmospheric CO2 levels were still under 300 ppm.
The “melt events around the Holocene Climate Optimum were more intense and more frequent” than has been observed during the modern period. And the most prominent melt events of the last 10,000 years centered around the Medieval Warm Period, 986 CE.
Overall, the elevation of the Greenland ice sheet has grown by 0.4 km since the Early Holocene, as “summer temperatures must have been at least 3 ± 0.6°C warmer during the Early Holocene compared to today.”

Jørgen Peder Steffensen is an Associate Professor at the University of Copenhagen and one of the world’s leading experts on ice cores. Using ice cores from sites in Greenland, he has been able to reconstruct temperatures there for the last 10000 years. So what are his conclusions?
Temperatures in Greenland were about 1.5 C warmer 1000 years ago than now.
It was perhaps 2.5 C warmer 4000 years ago.
The period around 1875, at the lowest point of the Little Ice Age, marked the coldest point in the last 10,000 years.
Other evidence from elsewhere in the Northern Hemisphere confirms this picture.
Pielke notes five points of fact about hurricanes:
The Intergovernmental Panel on Climate Change (IPCC) finds “no consensus” on the relative role of human influences on Atlantic hurricane activity, quoting the IPCC as follows: “there is still no consensus on the relative magnitude of human and natural influences on past changes in Atlantic hurricane activity, … and it remains uncertain whether past changes in Atlantic TC activity are outside the range of natural variability.”
“The IPCC has concluded that since 1900 there is ‘no trend in the frequency of USA landfall events.’ This goes for all hurricanes and also for the strongest hurricanes, called major hurricanes.”
“Since at least 1980, there are no clear trends in overall global hurricane and major hurricane activity.”
“There are many characteristics of tropical cyclones that are under study and hypothesized to be potentially affected by human influences, … but at present there is not a unified community consensus on these hypotheses, as summarized by the World Meteorological Organization,” as to whether any of the factors are affected by human greenhouse gas emissions.
“Hurricanes are common, incredibly destructive and will always be with us. Even so, we have learned a lot about how to prepare and recover.”
Pielke points out that some of the costliest hurricanes occurred in the early part of the twentieth century when average global temperatures were cooler than at present.

By the 1970’s, the Earth had experienced three decades of declining temperatures, which Hubert Lambdescribed as “longest-continued downward trend since temperature records began”.
Many will be aware that the coldest winter on record in the US was that of 1978/79, more than 1F colder than any other year.
The eruption of the Hunga Tonga-Hunga Ha’apai submarine volcano in January 2022 was one of the most explosive volcanic events of the modern era, a new study has confirmed.
Led by researchers from the University of Bath and published today in Nature, the study combines extensive satellite data with ground-level observations to show that the eruption was unique in observed science in both its magnitude and speed, and in the range of the fast-moving gravity and atmospheric waves it created.
Following a series of smaller events beginning in December 2021, Hunga Tonga erupted on 15 January this year, producing a vertical plume that extended more than 50km (30 miles) above the surface of the earth. Heat released from water and hot ash in the plume remained the biggest source of gravity waves on earth for the next 12 hours. The eruption also produced ripple-like gravity waves that satellite observations show extended across the Pacific basin.
The eruption also triggered waves in our atmosphere that reverberated around the planet at least six times and reached close to their theoretical maximum speeds — the fastest ever seen within our atmosphere, at 320m per second or 720 miles per hour.
The fact that a single event dominated such a large region is described by the paper’s authors as unique in the observational record, and one that will help scientists improve future atmospheric weather and climate models.
World leaders at the G7 summit in Germany signaled they will turn back to fossil fuels despite their commitments to a green energy transition thanks to the ongoing energy crisis.
The war in Ukraine is heavily restricting fuel imports, with Russia cutting off European access to the Nord Stream pipeline and the US imposing a fuel embargo on Putin. [bold, links added]
As a result, the U.S. and European countries are abandoning their climate agenda to return to fossil fuels.
Amid skyrocketing fuel prices, the Biden administration has been forced to abandon certain planks of its climate agenda.
Biden called for a temporary increase in domestic fuel production two weeks ago and also asked Congress to suspend the federal per-gallon gas tax for three months last week.
“The G7 leaders are pretending that nothing has happened to the green agenda,” Benny Peiser, director of the Global Warming Policy Forum, told The Daily Caller News Foundation. “In reality, if you look at individual member states… it’s quite obvious that the green agenda will be sunk.”
The New Pause paused last month because I was ill. Many apologies for the interruption. Now, however, it resumes – and it has lengthened from 7 years 7 months to the end of April 2022. To the end of June 2022, the New Pause is now 7 years 10 months in length:
This Pause, like its predecessor, which was an impressive 18 years 8 months (UAH), or 18 years 9 months (HadCRUT4), is, as always, not cherry-picked. It is derived from the UAH monthly global mean lower-troposphere temperature anomalies as the period from the earliest month starting with which the least-squares linear-regression trend to the most recent month for which data are available does not exceed zero. Whatever the data show, I show. Or, in the immortal words of Dr Roy Spencer, speaking of his dataset, “It is what it is”. In that splendid dictum speaks all true science.
The least-squares trend, which Professor Jones at the University of East Anglia used to recommend as the simplest and most robust method of deriving global-temperature trends, takes due account of all monthly values, not merely of the starting and ending values.
It is widely accepted that atmospheric pO2 < 1 ppm before the Great Oxidation Event. Yet a recent study found fossil micrometeorites (MMs) containing the oxidized iron species wüstite (FeO) and magnetite (Fe3O4) formed 2.7 billion years ago (Ga). How these MMs became oxidized is uncertain. Abundant O2 in the upper atmosphere and iron oxidation by CO2 have been suggested. However, photochemical reactions cannot produce sufficient O2, and oxidation by CO2 can only produce FeO, each individually failing to explain the formation of Fe3O4-only MMs. Using an oxidation model of iron MMs including photochemistry, we show that a >32% CO2 Archean atmosphere and different entry angles can generate the Fe3O4-only and Fe-FeO mixed composition MMs that have been discovered. Oxidation happens in two stages: by CO2 under brief melting, then by O2. Our results challenge existing constraints on Earth’s atmospheric CO2 concentration at 2.7 Ga and support a warm Late Archean despite the ‘faint young Sun’.
Could Antarctica’s ‘Doomsday Glacier’ meet its doom within 3 years?
“Time is melting away for one of Antarctica’s biggest glaciers, and its rapid deterioration could end with the ice shelf’s complete collapse in just a few years,” alarmist researchers warned at a virtual press briefing on Dec. 13, 2021 at the annual meeting of the American Geophysical Union (AGU)–a once outstanding professional society, but now a shill for the left.
Above is the first sentence of the article titled “Antarctica’s ‘Doomsday Glacier’ could meet its doom within 3 years,” not what we would expect to see from a once reputable source, the AGU. It warns us that in a few years, the world’s largest glacier, about the size of Florida, will melt and raise ocean levels by up to 3 meters (about 10 ft). It then tells us that the glacier is melting from below because the surrounding ocean waters have been warmed “thanks to human-induced climate change.” Finally, it tells us that a team of more than 100 scientists from the USA and the UK have been studying the Thwaites glacier and sharing their findings with scientists worldwide.
The article then explains that the Thwaites is not melting from above, but “the melting is coming from below,” from the warmed-up oceans that have been warmed by human-made CO2 and the greenhouse effect. The bulk of the article then proceeds to detail the forecasted consequences around the world:
…
This team may not have even been communicating with each other. Almost a decade earlier, geologists were seeing evidence of volcanoes in a known active tectonic plate boundary, buried under the glacier and the oceans. Before 2017, at least 47 volcanoes were found in western Antarctica and around the area of the Thwaites glacier. In 2017 the Guardian reported that an additional 91 volcanoes had been found along the western shores of Antarctica, with some sitting under the Twaites glacier itself. See the article “Scientists discover 91 volcanoes below Antarctic ice sheet.”
The tropical (20N-20S) anomaly for June was -0.36 deg. C, which is the coolest monthly anomaly in over 10 years, the coolest June in 22 years, and the 9th coolest June in the 44 year satellite record.
CO2 and water vapor greenhouse effect impacts are not independent climate forcings . A new study affirms the “variance in the radiance in these channels is primarily controlled by…temperature” and “atmospheric absorption is strongly saturated in these [CO2, water vapor] channels”.
It has previously been established that greenhouse gas (water vapor, CO2) forcing “cannot be considered an independent component of the surface energy budget” because “anomalies in the downward longwave flux at the surface primarily arise as a consequence of surface temperature anomalies, rather than being the cause of those anomalies” (Singh and Polvani, 2020, Zeppetello et al., 2019).
Feldman et al. (2015) admit they had to “construct” model-based spectra to simulate a CO2 signal in their seminal paper purporting to show CO2 changes cause temperature changes. This is because the temperature and water vapor levels primarily determine the overall longwave forcing (clear-sky) trends.

When speaking about the Intergovernmental Panel on Climate Change (IPCC) report Climate Change 2021: The Physical Sciences Basis, UN Secretary-General António Guterres declared it a “code red for humanity.”
He further stressed, “The alarm bells are deafening, and the evidence is irrefutable.” [bold, links added]
But a person who reads the report dispassionately and thoroughly will recognize that there is no code red for humanity and that the evidence is indeed refutable. It would be more accurate to say the report is a code red for sanity.
Classical science observes what is; that’s the evidence. A political agenda persuades what should be done; that’s the alarm bells.
Let’s turn off the alarm the IPCC pulled by examining Climate Change 2021: The Physical Science Basis (referred to from this point as “the report”).
The report has four major themes where the political agenda has overrun classical science.
Theme 1: Climate history was altered.
The IPCC would like you to believe that the Earth’s temperature has been constant for thousands of years and that the approximate 1°C of warming is unprecedented.
The report offers this figure to support that view:
Assessing the role of anthropogenic warming from temporally inhomogeneous historical data in the presence of large natural variability is difficult and has caused conflicting conclusions on the detection and attribution of tropical cyclone (TC) trends. [bold, links added]
Here, using a reconstructed long-term proxy of annual TC numbers together with high-resolution climate model experiments, we show robust declining trends in the annual number of TCs at global and regional scales during the twentieth century.
The Twentieth Century Reanalysis (20CR) dataset is used for reconstruction because, compared with other reanalyses, it assimilates only sea-level pressure fields rather than utilizing all available observations in the troposphere, making it less sensitive to temporal inhomogeneities in the observations.
It can also capture TC signatures from the pre-satellite era reasonably well.
The declining trends found are consistent with the twentieth-century weakening of the Hadley and Walker circulations, which make conditions for TC formation less favorable.
Human activities are estimated to have caused ~1.0 °C of global warming above pre-industrial levels, with most of the warming occurring since the mid-twentieth century1.
In bubbling vents off the coast of Ischia, a volcanic island in the Gulf of Naples, lives a curious population of black sea urchins. For at least 30 years, they have lived in these low pH, carbon dioxide-rich environments — a proxy for climate change-induced acidic oceans.
Now, University of Sydney researchers have determined they can also tolerate unprecedentedly warm sea temperatures — another climate change by-product. This means that these urchins, already one of the most abundant animals in the Mediterranean Sea, will likely plunder further afield as oceans continue to warm and become more acidic.
The researchers have described their findings in Biology Letters, a publication of the Royal Society.
The Mediterranean Sea is warming 20 percent faster than the global average, with predicted warming of up to 5.8°C by 2100.
“Given their ability to withstand a large temperature range, these sea urchins are likely to continue spreading throughout the Mediterranean Sea, with serious consequences for coastal habitats,” said lead researcher, University of Sydney marine biologist Dr Shawna Foo.
