That’s what it amounts to, even if the phrasing is different. Scenarios based on theories of climate that aren’t borne out by reality are the curse of modelling. All they seem to come up with is impossible demand reduction i.e. much less of everything – except renewables of course. It can’t get any better while their built-in CO2 obsession persists.

Renewable energy transition won’t come fast enough to solve the climate crisis—we also need to reduce global energy consumption, according to new research from UNSW Sydney.

The research, published recently in Climate Policy, models different energy-use scenarios for reducing global energy-related CO2 emissions to zero by 2050, says Phys.org.

It found that simply substituting fossil fuels with renewable energy at current energy usage levels is no longer enough.

Misleading climate models have a lot to answer for.

PA Pundits - International

By Dr. Jay Lehr and Robert Lyman~

That is a great question, and yes, there is a chance that it could happen. But it would not be meaningfully caused by humans burning fossil fuels and producing more CO2.

Additional CO2 in our atmosphere stopped having a meaningful role in the earth’s temperature when it reached 300 parts per million, and that portion of our atmosphere that absorbs CO2 was all used up. Seriously that is a fact. So today, adding any amount of more CO2 has no impact on climate whatever. If CO2 doubled from the present 420 parts per million (PPM) to 840 PPM, the earth would just get greener, and crops would increase their yields on every farm and every forest. There would be no negative impacts at all. Atomic submarines travel the world underwater with an average CO2 content of over 5,000 PPM. Yes, that is…

Earth and climate – an ongoing controversy


One person’s point of view is another’s ‘misinformation’ it seems. The BBC and others of a climate alarmist persuasion don’t understand, or won’t accept, that in real science differences of opinion can’t just be switched off or stigmatised.

A dozen scientists, politicians, and campaigners say they have been tricked into participating in online events promoting climate-change denial, say BBC News climate disinformation reporters.

The events were organised by the Creative Society, an international activist group that denies global warming is being caused by human activity.

The overwhelming majority of scientists agree greenhouse gases – which trap the Sun’s heat – are causing a rise in global temperatures.

The issue is leakage. In any case the notion of part of the supposed cure for ‘climate change’ being worse than the supposed disease is ironic. Germany imagines a future of so-called climate neutrality, a concept lacking any real-world meaning.

German Economy Minister Robert Habeck plans to import hydrogen from all over the world to satisfy Germany’s hunger for energy despite a new study questioning the climate-friendliness of hydrogen transport, EURACTIV Germany reports.

One thing is clear to all politicians and experts: Germany is an energy importing country.

To move towards climate neutrality, the German government wants to rely primarily on importing hydrogen molecules from all over the world – efforts which have been further accelerated due to the war in Ukraine and Germany’s dependence on Russian energy imports.

With an energy cost crisis now striking Europe and to a lesser extent the U.S., some cracks have begun to appear in the “net zero” utopian dreams being pursued almost universally by Western politicians, says the Manhattan Contrarian.

Nevertheless, at this writing, the rapid elimination of use of fossil fuels, supposedly to fight “climate change,” remains official government policy throughout Europe, at the federal level in the U.S., in most blue American states, and as well in Canada, Australia and New Zealand.

What evidence is there that such powers do exist? An air of unreality is palpable here, with talk of extreme dangers and use of decimal point temperature statements while brushing aside all uncertainties. Endless alarmism creates fatigue, not the fear they crave.

UN scientists have unveiled a plan that they believe can limit the root causes of dangerous climate change, says BBC News.

A key UN body says in a report that there must be “rapid, deep and immediate” cuts in carbon dioxide (CO2) emissions.

Global emissions of CO2 would need to peak within three years to stave off the worst impacts.

Even then, the world would also need technology to suck CO2 from the skies by mid-century.

The short answer to the climate question.

Science Matters

This post is about proving that CO2 changes in response to temperature changes, not the other way around, as is often claimed.  In order to do  that we need two datasets: one for measurements of changes in atmospheric CO2 concentrations over time and one for estimates of Global Mean Temperature changes over time.

Climate science is unsettling because past data are not fixed, but change later on.  I ran into this previously and now again in 2021 and 2022 when I set out to update an analysis done in 2014 by Jeremy Shiers (discussed in a previous post reprinted at the end).  Jeremy provided a spreadsheet in his essay Murray Salby Showed CO2 Follows Temperature Now You Can Too posted in January 2014. I downloaded his spreadsheet intending to bring the analysis up to the present to see if the results hold up.  The two sources of data were:

The carbon cycle [credit: laurencenet.net]


Carbon cycle alarm has so far failed to materialise, this research finds.
– – –
Researchers have constructed a new time series for global carbon emissions from deforestation, reports Phys.org.

The series is the missing link in terms of the improved understanding of the global carbon cycle, and it implies that the natural uptake of CO2 by the land and oceans is more efficient than previously assumed.

The study shows that carbon emissions from deforestation between the 1960s and 1980s were lower than previous studies had assumed.

Thirty-eight emails released under a recent FOI request provide an interesting insight into the way Government science advisers plotted to change Boris Johnson’s mind over the causes of climate change, ahead of a Cabinet Office presentation, says The Daily Sceptic.

The event on January 28th 2020 was led by the Government’s Chief Scientific Officer Sir Patrick Vallance and presented, using 11 slides, by the Chief Scientist of the Met Office, Professor Stephen Belcher.

According to Belcher, the stated goal of the presentation was to “stabilise climate which requires net zero emissions”.

Biomass on the move [image credit: Drax]


The whole ‘net zero’ thing is a scandal in many ways, but at least some MPs are noticing one of the issues, even if partly for the wrong reason. Burning trees isn’t a solution to anything apart from papering over a few of the cracks in electricity supply caused by intermittent renewables.

Burning wood to create power is a ‘scandal’, 50 MPs warn the energy minister in a letter today.

The letter – which has cross-party support – marks a major shift in political opinion over the burning of biomass, which is currently classed by the Government as a green form of energy, says the Daily Mail.

The letter says the extra emissions produced by biomass ‘are the equivalent of three million Ford Fiestas on our roads’.

Organised by Peter Bottomley, Father of the House of Commons, the letter calls for a meeting with Business and Energy Secretary Kwasi Kwarteng to discuss ending subsidies to the Drax power plant in Yorkshire.

King coal is dead, long live king coal! That might be a fitting epitaph for COP26, which mercifully ended last Friday, says Climate Change Dispatch.

It culminated with an agreement, which had not so much been watered down as to have virtually evaporated. Fossil fuels, it seems, are here for the foreseeable.

What went wrong? That’s a question the ‘deeply frustrated’ COP26 president Alok Sharma might well be asking himself.

He appeared to be close to tears at the denouement of the negotiations, pushed to emotional extremis by the last-minute wrangling over a single word: should we commit ourselves to phase out our use of coal, or phase- down our use of coal.

The distant past of Earth and potentially its future include extremely warm ‘hothouse’ climate states, but little is known about how the atmosphere of our planet behaves in such states, says Sci-News.

“If you were to look at a large patch of the deep tropics today, it’s always raining somewhere,” said Dr. Jacob Seeley, a postdoctoral researcher at Harvard University.

“But we found that in extremely warm climates, there could be multiple days with no rain anywhere over a huge part of the ocean.”

“Then, suddenly, a massive rainstorm would erupt over almost the entire domain, dumping a tremendous amount of rain. Then it would be quiet for a couple of days and repeat.”

How many millions of years might that be then? Two, apparently: CO2 level ‘is greater than at any time in at least the past 2 million years’. What about earlier times? The caption to the first photo in the article reads: ‘The near future may be similar to the mid-Pliocene warm period a few million years ago.’ So natural variation is confined to history, and/or dependent on volcanoes? The article asserts: ‘the last warm period between ice ages peaked about 125,000 years ago—in contrast to today, warmth at that time was driven not by CO₂, but by changes in Earth’s orbit and spin axis.’ Now orbital factors have also switched themselves off? And so it goes on: our climate models say…

Many numbers are swirling around the climate negotiations at the UN climate summit in Glasgow, COP26, says Phys.org.

These include global warming targets of 1.5℃ and 2.0℃, recent warming of 1.1℃, remaining CO₂ budget of 400 billion tons, or current atmospheric CO₂ of 415 parts per million.

It’s often hard to grasp the significance of these numbers. But the study of ancient climates can give us an appreciation of their scale compared to what has occurred naturally in the past.

Our knowledge of ancient climate change also allows scientists to calibrate their models and therefore improve predictions of what the future may hold.

Everyone who matters from the Biden administration wants to be seen as ‘caring about the planet and doing something about climate change. They are now tripping all over themselves to head to the upcoming United Nations climate conference.

Nearly everyone else attending this conference will be looking for—actually, demanding—a handout from the U.S. and the other more economically advanced nations in the European Union (EU) and elsewhere.

President Joe Biden and at least 13 senior officials from his administration will be traveling to Glasgow, Scotland for the United Nation’s 26th Conference of the Parties to the Framework Convention on Climate Change (“UNFCC/COP26”). Conference attendees will be gathering, interestingly, on Halloween, with formal sessions starting the following day.

Accompanying the president will be Special Climate Envoy, John Kerry; Secretary of State, Anthony Blinken; the EPA administrator, the USAID administrator, secretaries of Energy, Interior and Transportation…

CO2 is not pollution

Another reason to reduce or avoid credit card usage.

Get ready for a Chinese-style social credit system scoring when it comes to your personal spending habits and how they impact “climate change”, says Marc Morano at Climate Depot.

A new credit card called Doconomy, has launched that is “working in tight collaboration with Mastercard” and an alliance with the UN Framework Convention on Climate Change (UNFCCC) is now available so you can monitor your personal CO2 budget on every purchase you make.

The new CO2 monitoring Mastercard called Doconomy debuted in order to enable “all users to track, measure and understand their impact by presenting their carbon footprint on every purchase.”

The credit cards feature the slogan on them reading “DO. Everyday Climate Action” and have a personal pledge on the rear of the card boasting: “I am taking responsibility for every transaction I make to help protect the planet.”

The Mastercards feature the UN “Global Climate Action” logo on them as well.

Known in the UK as Tradable Energy Quotas (TEQs), this idea dates back to at least 2004. This is where ’emissions’ obsession can lead. Even your sausage buying would have to be recorded.

Swiss climate experts propose the introduction of an individual CO2 budget so Switzerland can reach its goal of “net zero greenhouse gas emissions” by 2050, says Swissinfo.

The radical proposal for Swiss climate policy was presented in the Sunday weekly newspapers Le Matin Dimanche and NZZ am Sonntag.

The central premise is that all goods would have two prices – one in Swiss francs and the other in CO2 emissions. This would factor the amount of CO2 released in everything from sausage making to short-haul flights.

A key premise of most computer models seems to be that the atmosphere, with its 0.04% CO2 content, drives ocean temperatures. As most of the energy is in the oceans, why wouldn’t it be the other way round?

The cycling between warm El Niño and cold La Niña conditions in the eastern Pacific (commonly referred to as the El Niño-Southern Oscillation, ENSO) has persisted without major interruptions for at least the last 11,000 years, says Phys.org.

The team conducted a series of global climate model simulations with an unprecedented spatial resolution of 10 km in the ocean and 25 km in the atmosphere.

Alarmist CO2 hokum on the rise.

PA Pundits - International

By David Wojick, Ph.D. ~

Many of my disagreements with the IPCC AR6 science Summary for Policy Makers (SPM) are just that, disagreements. I think their reasoning is faulty but at least I understand it. See my last article — The UN IPCC science panel opts for extreme nuttiness.

One SPM section, however, is so wrong that it must be a deliberate deception. The purpose seems to be to make the atmospheric CO2 increase look like a simple accumulation of our emissions. I call this the pollution model of CO2 and it is extremely misleading. The truth is well known so this must be a deceptive act on the IPCC’s part.

Here is the opening summary paragraph. The first sentence is a ridiculous 51 tortured words long, the second (and last) sentence states the hoax very clearly.

While natural land and ocean carbon sinks are projected…

HMG pays another visit to climate cloud cuckoo land. Its hydrogen ‘strategy’ turns out to be as full of obvious holes as a string vest. Don’t even ask about safety issues.
– – –
The UK’s long-awaited hydrogen strategy has set out the government’s plans for “a world-leading hydrogen economy” that it says would generate £900 million (US$1.2 million) and create over 9,000 jobs by 2030, “potentially rising to 100,000 jobs and £13 billion by 2050”. From: The Conversation (via Phys.org).

The strategy document argues that hydrogen could be used in place of fossil fuels in homes and industries which are currently responsible for significant CO2 emissions, such as chemical manufacturing and heavy transport, which includes the delivery of goods by shipping, lorries and trains.

The government also envisages that many of the new jobs producing and using “low-carbon hydrogen” will benefit “UK companies and workers across our industrial heartlands.”

On the face of it, this vision of a low-carbon future in some of the most difficult to decarbonise niches of the economy sounds like good news. But is it? And are there other options for delivering net zero that will be better for the public?
