Nature’s carbon cycle still working as expected.

Increased levels of carbon dioxide in the atmosphere have contributed to a rise in wood volume or biomass of forests in the US, according to a new study.

The research, published recently in the Journal Nature Communications, found that elevated carbon levels have led to a consistent increase in wood volume in 10 different temperate forest groups across the US, says The Independent.

By bulking up this way, trees are helping shield Earth’s ecosystem from the impacts of global warming, say scientists, including those from the Ohio State University.

Economic disaster beckons without radical policy changes, says Net Zero Watch.

London, 27 September – Net Zero Watch has said that negative market reactions to the Government’s mini-budget show that domestic and international investors are highly sceptical about what appears to be half-baked policy proposals.

Investors can see that hardly anything is being done to address the underlying reasons for Britain’s economic and energy cost crisis.

Tax cuts in conjunction with astronomical and indeterminate handouts to energy suppliers announced by the Chancellor Kwasi Kwarteng last week have alarmed financiers because they shift the energy cost burden onto the UK’s debt mountain and future generations. As a result, the pound has crashed against the dollar and market reactions have been highly critical.

Net Zero Watch director, Dr Benny Peiser has warned that the country faces years of inflation and in all likelihood a major economic depression unless the government announces radical energy policy reforms:

The economy looks likely to tank and suffer for years to come because the Government refuses to abandon its suicidal Net Zero targets which are effectively preventing solutions to the catastrophic energy crisis.”

The authors propose that sea-ice formation is the key factor and not biology. In their paper, we read: ‘Results: Carbon dioxide is very strongly correlated with sea ice dynamics, with the carbon dioxide rate at Mauna Loa lagging sea ice extent rate by 7 months.’ However, drawing conclusions from correlations can go wrong. The authors conclude: ‘If sea ice does not drive the net flux of these gases, it is a highly precise proxy for whatever does. Potential mechanisms should be investigated urgently.’

Could we be wrong about the annual cycle of carbon dioxide in the atmosphere? – asks Net Zero Watch.

That’s the suggestion by a pair of distinguished Oxford zoologists Clive Hambler and Peter Henderson who have just published a paper that could change our understanding about one of the key observations of this greenhouse gas.

They propose that sea-ice formation is the key factor and not biology.

CO2 is not pollution


In the end nature determines how much of the trace gas carbon dioxide is in the atmosphere, via the carbon cycle. Certain human activities may alter the numbers up or down temporarily. There’s vast expense, including lots of pipelines nobody wants, with no known finishing line in so-called ‘carbon capture’.
– – –
Up to a fifth of emissions cuts from the Inflation Reduction Act are expected to come from carbon capture technologies, but there are major technical and political hurdles, says Climate Home News.

US president Joe Biden is expected to sign off a sweeping climate, energy and health care bill on Tuesday (16 August). It contains about $370 billion to foster clean energy development and combat climate change, constituting the largest federal climate investment in history.

Several studies project that its climate and energy provisions could enable the United States to reduce its greenhouse gas emissions by around 40% below 2005 levels by 2030.

Seabed mining


The ‘energy transition’ is supposed to replace thousands of coal-fired power stations and over a hundred million barrels of oil per year, amongst other fuels like gas and wood, in the name of an invented ‘climate crisis’. Not going to happen on the scale required, even if this new supply of minerals were to become available – with the aid of fossil fuel powered machinery. All that mining will, or would be, waste product one day.
– – –
A growing number of countries are demanding more time to decide on rules that would allow companies to mine the deep seabed for minerals needed to manufacture batteries for the energy transition, says Climate Change News.

Last year, the small island state of Nauru, triggered a never-before-used procedure giving the International Seabed Authority (ISA), the UN body which regulates mining activities in international waters, until July 2023 to fast-track deep sea mining exploitation rules.

Countries have discussed mining the bottom of the oceans for years but no commercial extraction has started in international waters. The ultimatum would allow the nascent industry to apply for mining permits as soon as next year.

The ocean carbon cycle [credit: IAEA]


“Based on our model calculations, we assume that current estimates of oceanic carbon uptake must be substantially corrected upwards”, said one researcher. A major revision, of ‘roughly 10% of our carbon budget’, is suggested. Phytoplankton hold the key.
– – –
Phytoplankton need light and nutrients to grow. The microscopic algae rarely find both at the same time in sufficient quantities in the ocean. In the upper water layers, they usually lack nutrients, and further down, they lack light.

A new study led by the Helmholtz Center Hereon now says: Phytoplankton can migrate back and forth between deeper layers and the water surface.

If this were confirmed, it would have enormous consequences for the calculations of the natural carbon pump and thus for current calculations of the carbon budget.

The ocean carbon cycle [credit: IAEA]


COP26 is over, in case anyone hasn’t noticed. “Anyone aspiring to lead our country needs to demonstrate that they take this issue incredibly seriously,” Alok Sharma says. The real issue is that Britain’s tiny contribution to the 0.04% portion of the atmosphere that is carbon dioxide amounts to much ado about nothing. The majority of that 0.04% is naturally caused anyway, and most so-called greenhouse gas is water vapour. What is all the fuss supposed to be about?
– – –
Alok Sharma, who led last year’s COP26 climate conference in Glasgow, has threatened to quit if the new prime minister ditches the current commitment to reach net zero carbon emissions by 2050, reports Sky News.

The cabinet minister said a failure to follow the policy backed by Boris Johnson would cause “incredible damage” to the UK’s international reputation.

Mr Sharma also accused some of the candidates in the Tory leadership contest of being “lukewarm” on net zero.

CO2 is not pollution


The researchers are not going overboard with positivity, but seem clear that the Earth’s carbon cycle is still working much as expected. Unsurprisingly perhaps, they theorise problems might occur by 2100 if some presently unknown limit is approached, but say ‘the Twilight Zone region of the ocean’ needs more research. In short, so far so good.
– – –
The amount of carbon stored by microscopic plankton will increase in the coming century, predict researchers at the University of Bristol and the National Oceanography Centre (NOC).

Using the latest IPCC models (Intergovernmental Panel on Climate Change), the team expects the “biological pump”—a process where microscopic plants, often called phytoplankton, take up carbon and then die and sink into the deep ocean where carbon is stored for hundreds of years—to account for between 5 and 17% of the total increase in carbon uptake by the oceans by 2100.

Their findings were published today in the journal PNAS (Proceedings of the National Academy of Sciences), says Phys.org.

Lead author Dr. Jamie Wilson, of the University of Bristol’s School of Earth Sciences, explained, “The biological pump stores roughly double the amount of carbon dioxide that is currently in our atmosphere in the deep ocean. Because plankton are sensitive to climate change, this carbon pool is likely to change in size, so we set out to understand how this would change in the future in response to climate change by looking at the latest future projections by IPCC models.”

Microscopic organisms called plankton, living in the sunlit surface of the ocean, use carbon dioxide during photosynthesis. When these plankton die, their remains rapidly sink down through the “Twilight Zone” of the ocean (200–1000m), where environmental factors, such as temperature and oxygen concentration, and ecological factors, such as being eaten by other plankton, control how much reaches the deep ocean where the carbon from their bodies is stored away from the atmosphere for hundreds to thousands of years.

Warming of the oceans slows down the circulation, increasing the time that carbon is stored in the deep ocean.

Contributing author Dr. Anna Katavouta, who worked alongside early-career scientist Dr. Chelsey Baker, both from the National Oceanography Centre, added, “Our research found a consistent increase in the carbon stored in the ocean by the biological carbon pump over the 21st century in the latest IPCC model projections. In contrast, we found a decline in the global export production (the amount of organic matter, such as dead plankton, sinking below the ocean surface), which suggests that export production may not be as accurate a metric for the biological carbon pump than previously thought. We demonstrated that the organic matter flux at 1000 meters is instead a better predictor of long-term carbon sequestration associated with the biological carbon pump. This outcome will help us to better understand the processes that control the biological carbon pump and to predict more reliably how much of the carbon released due to human activity will be stored in the ocean in the future.”

However, the IPCC models have no consistent representation of the environmental and ecological processes in the Twilight Zone. This leads to a large uncertainty in how much carbon dioxide originating from the atmosphere the biological pump will store beyond the end of the century.

In theory, after 2100, carbon storage by the biological pump could stall and instead may start acting as a source of carbon dioxide to the atmosphere, which could exacerbate climate change further.

Democracy overseeing the flow of EPA climate edicts? A ‘huge blow’, say alarmists, as over-the-top reactions from some of the usual suspects pour in.
– – –
This means Congress will now have to pass off on any climate regulations, says Energy Live News.

In what’s been considered a blow to climate mitigation in the US, the Supreme Court has ruled against the Environmental Protection Agency (EPA).

This means the EPA will now be limited in how it can regulate greenhouse gas (GHG) emissions and help stave off global warming in the country.

Los Angeles, CA


Desperately seeking ‘carbon’ capture. One of the obvious problems of course is that it’s energy-intensive, and that energy has to be generated by non-fossil sources to qualify as suitable for the job, in the eyes of climate obsessives. Ignoring other practical difficulties (storage etc.), where is all the extra power supposed to come from? If wealthy California can’t resolve such issues, most other climate-obsessed regions (excluding those with lots of hydro-power) will surely also struggle to do so, and it all has to be paid for. For ‘ambitious’ read ‘unworkable’?
– – –
California air regulators are likely to hear a barrage of criticism Thursday on a plan to slash fossil fuel use and reach carbon neutrality by 2045, a proposal that would require a sweeping shift in how the state powers its massive economy in the face of climate change, says Phys.org.

It will be the California Air Resources Board’s first public discussion of this year’s draft scoping plan, which is updated every five years and lays out a roadmap for the state to reach its climate goals.

The 2045 goal is among the most ambitious in the nation, but the proposal has many critics beyond the oil industry, which says the strategy has too many bans and mandates.

The net zero emissions concept is once again exposed as a Hollywood-type fantasy. Regardless of whether carbon dioxide is seen as a credible climate problem or not, it just isn’t achievable in time.
– – –
The goal of the U.S. government is to achieve net-zero carbon emissions by 2050, per the Paris agreement, says the Washington Examiner.

A three-step analysis establishes this as an impossible goal.

Three possible alternatives — wind, nuclear power, and utility photovoltaic solar (PV) — are analyzed separately in a three-step process to determine the amount of new capacity needed for any of them to meet net-zero carbon by 2050.

The same process then is used to determine whether any combination of the three can achieve the goal.

Mars from NASA’s Hubble Space Telescope


The hunt is now on for the offending ‘missing ingredient’: “Carbon dioxide is a strong greenhouse gas, so it really was the leading candidate to explain the drying out of Mars,” said Kite, an expert on the climates of other worlds. “But these results suggest it’s not so simple.” The article calls this ‘unusual’, but is what it considers usual really so?
– – –
Mars once ran red with rivers, says Phys.org.

The telltale tracks of past rivers, streams and lakes are visible today all over the planet.

But about three billion years ago, they all dried up—and no one knows why.

“People have put forward different ideas, but we’re not sure what caused the climate to change so dramatically,” said University of Chicago geophysical scientist Edwin Kite. “We’d really like to understand, especially because it’s the only planet we definitely know changed from habitable to uninhabitable.”

CO2 is not pollution


Carbon removal? Nature does that job. Carbon pollution? Plants and vegetation require carbon dioxide to grow. Investing? They must be joking. Subsidising foolish ideas isn’t much of an investment.
– – –
The US Energy Department launched a program on Thursday to fund four large-scale projects across the country that can remove carbon dioxide from the air, investing $3.5 billion in a nascent technology the Biden administration says is necessary to meet a goal of achieving net zero emissions by mid century, reports msn.com.

The UN’s Intergovernmental Panel on Climate Change released a report last month that said the world will need “carbon dioxide removal” technologies – ranging from planting trees that soak up carbon to grow, to costly technologies to suck carbon dioxide directly from the air to meet global goals to curb climate change.

“The UN’s latest climate report made clear that removing legacy carbon pollution from the air through direct air capture and safely storing it is an essential weapon in our fight against the climate crisis,” said Energy Secretary Jennifer Granholm.

Domestic Air Source Heat Pump [image credit: UK Alternative Energy]


The ill-conceived ‘net zero’ emissions plan born of the UK government’s carbon dioxide obsessions takes another hit. Five-figure radiator installation bills will put people off bigtime.
– – –
Homeowners trying to install eco-friendly heat pumps have been left with surprise £30,000 bills after it emerged millions of radiators are too small to work with the new technology, says The Telegraph.

The Government wants 600,000 heat pumps installed every year by 2028, in line with its “net zero” aims, but the majority of homes may need thousands of pounds worth of upgrades to accommodate them.

Heat pumps need larger radiators to achieve the same heat output as gas boilers, which heat water to much higher temperatures.

Some 99pc of British homes do not have radiators large enough to heat a room on the coldest winter’s day, using a low-temperature heat pump, the most common model, according to a Department for Business, Energy & Industrial Strategy study.

“High temperature” heat pumps can help fix this but 90pc of homes would still need better radiators.

Climate neutrality is an imaginary goal. In reality it doesn’t exist but the phrase serves as a peg to hang an EU publicity gimmick on, as they try to imply it can make people healthier — among other dubious assertions.
– – –
One hundred European cities have been selected to participate in an EU programme to rapidly cut emissions in urban areas, with the aim of reaching climate neutrality by 2030, says Euractiv.

Cities drawn from each member state will participate in the scheme, representing some 12% of the EU population.

A further 12 cities from outside of the bloc will take part.

The EU will invest €360 million to aid cities in their greening mission in 2022 and 2023, which it is hoped will spur further investments from the private sector.

Photosynthesis: nature requires carbon dioxide


A Climate Overshoot Commission (COC?) will try to dream up ways of altering nature’s carbon cycle. The mind boggles at the futility.
– – –
Fifteen former leaders and ministers are set to address sensitive questions on the role of CO2 removal and geoengineering in climate action, reports Climate Home News.

The chances of keeping global temperature rise below 1.5C, the toughest goal of the Paris Agreement, are increasingly slim. “Well below 2C” is a stretch.

Yet there has been little discussion at an international level on how to handle “overshoot” of those goals. A high-powered commission due to launch in May aims to break the silence.

Climate diplomats are finalising a 15-strong lineup of former presidents, ministers and representatives of international organisations to explore options for deep adaptation, carbon dioxide removal (CDR) and geoengineering, Climate Home News can reveal.

Hapless climate botherers barking up the wrong tree again? Carbon dioxide capture should be left to nature.

In a new paper published in Frontiers in Forests and Global Change the scientists look at the climate effects of deforestation at different latitudes, says Net Zero Watch.

The researchers find that at latitudes 50°N to 60°N – in other words essentially all of the UK – and above, deforestation contributes to global cooling, so afforestation (which has opposing effects to deforestation) will contribute to global warming.

A deal between Sweden’s political parties positions the country to take responsibility for the carbon footprint of imported goods, says Climate Home News.

Sweden’s political parties agreed on Thursday to include consumption-based emissions within its climate targets, making it the first country in the world to make the leap into the complex realm of overseas emissions reporting.

National climate targets rely on reporting the emissions that are created on a country’s territory.
