Photosynthesis: nature requires carbon dioxide

‘What is carbon dioxide, anyway? How does it cause global warming?’ – asks [Delete ‘how’ – says the Talkshop.] Anyway, the entire article they attach to their loaded-question headline never once mentions water vapour. It’s all about demonising CO2. Even climate worrier Wikipedia says: ‘Water vapour is the gaseous phase of water…Being a component of Earth’s hydrosphere and hydrologic cycle, it is particularly abundant in Earth’s atmosphere, where it acts as a greenhouse gas and warming feedback, contributing more to total greenhouse effect than non-condensable gases such as carbon dioxide and methane.’ So even for fans of greenhouse theories there’s no escaping the predominance of water vapour over carbon dioxide. Completely ignoring it makes the whole CO2-promoting article redundant.

Chemically, carbon dioxide is incredibly simple—it is just one carbon atom linked with two oxygen atoms, says

Together they create a colorless gas that makes up just a tiny fraction of the Earth’s atmosphere, about 0.04%.

That gas is critical to life on earth because plants use sunlight and carbon dioxide to create energy through the process of photosynthesis.

But carbon dioxide is also the primary reason the climate is warming, a long-term shift in temperature that threatens the delicately balanced ecosystems humans depend upon.

So how is something so necessary to life also so harmful? Here’s what to know:

According to the clerics of the Green Cult, once we blow up our last coal mine, send all diesel engines to the wreckers, stop using concrete, reinvent sailing clippers, cover the grasslands and hills with solar clutter and wind machines, and then slaughter all of our cattle… global climate will become serene – not too warm, not too cold, writes Viv Forbes (via Climate Change Dispatch).

Wild weather will cease, and there will be no more droughts, floods, cyclones, or snowstorms and no more plant and animal extinctions.

But the records written in the rocks tell a far different story about climate changes. Even when nature was in full control, it was not a serene place.


As a starting point to the discussion, a graph is shown with a correlation between seismic activity and temperature over the last 40+ years. The author’s closing comment: ‘So the oceans are “boiling” and apparently Al Gore has a magic co2 fairy that is doing it.’

I will be brief ( relatively), says meteorologist Joe Bastardi @ CFACT.

In a paper coming out, “Increased Mid-Ocean Seismic Activity: Fact or Artifact?” Dr. Arthur Viterito has confirmed my suspicions that geothermal input from the increased seismic activity is a leading cause of the warming, if not the almost total cause.

As much as the co2 crowd keeps pointing to the rise in temperature and increased emissions they ignore the fact that the air temperatures go virtually nowhere without the oceanic warming and the input of WV in the air.

The oceans are not warming via co2 feedback. Arguments about co2’s effect on the air ignore the oceanic warming.

So what is warming the ocean? Dr Viterito supplies the smoking gun to my suspicions.

Al Gore WEF Meltdown: ‘Boiling the Oceans,’ ‘Rain Bombs,’ a Billion ‘Climate Refugees’ — Breitbart News

The last El Niño was 6-7 years ago, but elapsed time can’t on its own be a guarantee of one this year. Neutral ENSO conditions are another option. As usual an assertion about warming from greenhouse gases is thrown in, with no evidence to back it up.

Climate models indicate La Niña is on the way out, with El Niño conditions expected later this year, claims

CSIRO Climate Scientist Dr. Wenju Cai explains what this means for Australia’s weather and how changing conditions will affect the country.

Is La Niña really on the way out? What do the climate models tell us?

We are in the mature season of the current three-consecutive La Niña years. During the three years, heat has been stored in the equatorial Pacific Ocean.

It is really time for us all to stop taking any of the information broadcast out of the annual United Nations climate conferences called Conference Of The Parties seriously. The 27th such conference which convened in Egypt this month concluded with the following statement.

The Conference of the PartiesHighlights that about USD 4 trillion per year needs to be invested in renewable energy up until 2030 to be able to reach net zero emissions by 2050.” That which would eliminate all life on earth that depends on carbon dioxide which is all life on earth.

It does not include reparations for loss and damage. That potentially much greater financial flow (as it is called in UN speak) is extra.

The precise nature of this called for transformation of the financial system is not specified but easy money seems a…

Recent data tell a somewhat different story to the one NASA want to put forward. The mean rate of change in September minima reduced to something akin to zero after 2007, maybe even a small (relative to the 1980 peak) rise.

‘Key Takeaway: Summer Arctic sea ice extent is shrinking by 12.6% per decade as a result of global warming’, says NASA.

But their own interactive ‘ANNUAL SEPTEMBER MINIMUM EXTENT’ graph (here) gives the game away. For example:

2007 minimum: 4.07 km. (lowest since 1979, at the time).
2021: 4.72 km.
2022: 4.67 km.

Only two of the last fifteen years (2012, 2020) were lower than 2007, the rest at least the same (2016) or upto 25% above.

Peak decline was from 1996-2007, about one solar cycle (SC 23). Those days seem to have gone, for now at least. The most recent decade did not show a decline anywhere near 12.6%, or even any net decline.

September minima for 2021 and 2022 were both noticeably higher than those of 2011 and 2012, for example.

Of course the Met Office doesn’t have ‘forever’ data. The two main factors here seem to be the recovery from the Little Ice Age (not mentioned) and El Niño/La Niña effects, which are admitted to be a, if not the, dominant factor. Human-caused effects are asserted but evidence is lacking.
– – –
2023 is set to be one of the world’s hottest years ever as the temperatures continue to rise, says the Bournemouth Daily Echo.

It comes as the Met Office has predicted that global temperatures will be at least 1C above pre-industrial levels.

They added that in 2023, the global average temperature will be around 1.2C above what they were before humans impacted climate change.


It’s ‘study suggests’ time again. NZW: They say (p 4283) it’s a credible hypothesis that global temperature trend changes since 2000 could be “arising largely from internal variability.”
— These results definitely won’t please the climate obsessive tendency.

A new study by a team of leading climate scientists suggests that the effect of carbon dioxide this century might be small when compared to natural climate variability, says Net Zero Watch.

Global surface temperature is, and always has been, the key climate parameter.

Whatever is happening to the Earth’s climate balance, it must, sooner or later, be reflected in the global annual average temperature, and not just in regional variations.

But therein lies what is to some an inconvenience, as the changes in the global temperature this century is open to differing interpretations including the suggestion that increases in anthropogenic greenhouse gas emissions are not needed to explain the changes we have seen in the last 20 years or so.

It’s a conclusion that many would dismiss as coming from climate “sceptics,” or downright deniers. But what if it’s the view of scientists from two of the world’s leading institutes researching climate change; the University of Oxford and the US National Center for Atmospheric Research. Then it must be taken seriously and not dismissed offhand.

It is important research because it is the trend in the increase of global temperature caused by anthropogenic greenhouse gas emissions that is most important variable for policymakers considering the scale and timescale of action in the coming decades.

However, this vital parameter is uncertain because recent decades have shown that we are living through a period of considerable natural climate variability.

Windy enough today?

This recent Yale Environment360 article came into focus today when Sky News headlined with: Future of renewable energy in balance as UK suffers wind drought – with ‘global stilling’ to come. Ironically, climate theory has it that warming will happen and will reduce wind speeds over the decades ahead. According to one expert (says Yale), a 10 percent decline in wind speeds would actually result in “a 30 percent drop [in output], and that would be catastrophic.”
– – –
Last year, from summer into fall, much of Europe experienced what’s known as a “wind drought,” says Yale.

Wind speeds in many places slowed about 15 percent below the annual average, and in other places, the drop was even more pronounced.

It was one of the least windy periods in the United Kingdom in the past 60 years, and the effects on power generation were dramatic.

Wind farms produced 18 percent of the U.K.’s power in September of 2020, but in September of 2021, that percentage plummeted to only 2 percent. To make up the energy gap, the U.K. was forced to restart two mothballed coal plants.

From airborne observations, these researchers find ‘trade-wind clouds are far less sensitive to global warming than has long been assumed’. Their study says: ‘Our observational analyses render models with large positive feedbacks implausible’. Consequently, they believe, extreme rise in Earth’s temperatures is less likely than previously thought.

In a major field campaign in 2020, Dr. Raphaela Vogel who is now at Universität Hamburg’s Center for Earth System Research and Sustainability (CEN) and an international team from the Laboratoire de Météorologie Dynamique in Paris and the Max Planck Institute for Meteorology in Hamburg analyzed observational data they and others collected in fields of cumulus clouds near the Atlantic island of Barbados.

Their analysis revealed that these clouds’ contribution to climate warming has to be reassessed, says Eurekalert.

“Trade-wind clouds influence the climate system around the globe, but the data demonstrate behavior differently than previously assumed. Consequently, an extreme rise in Earth’s temperatures is less likely than previously thought,” says Vogel, an atmospheric scientist.


Space satellite orbiting the earth

An academic attempt to gloss over some glaring discrepancies between results from theory-based climate models and observed data. The research paper says: ‘Climate-model simulations exhibit approximately two times more tropical tropospheric warming than satellite observations since 1979’. Over forty years of being so wrong, by their own admission, takes a lot of explaining.
– – –
Satellite observations and computer simulations are important tools for understanding past changes in Earth’s climate and for projecting future changes, says Lawrence Livermore National Laboratory (via

However, satellite observations consistently show less warming than climate model simulations from 1979 to the present, especially in the tropical troposphere (the lowest ~15 km of Earth’s atmosphere).

This difference has raised concerns that models may overstate future temperature changes.

Does the claim here that ‘almost every part of the ocean is heating up’ stand up to scrutiny? The article appears to contradict itself when stating ‘this cooling is the product of upwelling caused by the collision of a deep ocean current’ and referring to an ‘icy current’. The researchers say ‘this cooling water is fighting a losing battle with a warming atmosphere’, but deep ocean currents are by definition a long way from the surface most of the time.
– – –
A geological coincidence placed the Galapagos Islands in the line of an icy current that provides food and shelter in a warming ocean, says Hakai Magazine.

The good news might not last for long.

Pushed by climate change, almost every part of the ocean is heating up. But off the west coast of the Galapagos Islands, there is a patch of cold, nutrient-rich water. This prosperous patch feeds phytoplankton and breathes life into the archipelago.

The article below links to another one which appears to contradict it. In ‘The threshold between natural Atlantic current system fluctuations and a climate change-driven evolution’ we’re told ‘natural variations are still dominant’ in the AMOC or “Gulf Stream System.” Then the key part:
‘According to the researchers, part of the North Atlantic is cooling—a striking contrast to the majority of ocean regions. All evaluations indicate that since the beginning of the 20th century, natural fluctuations have been the primary reason for this cooling. Nonetheless, the studies indicate that the AMOC has started to slow down in recent decades.’ If the slowdown occurred under cooling, why should future warming be likely to cause more of it?

– – –
For decades, oceanographers have been measuring the Atlantic Meridional Overturning Circulation (AMOC), a large system of ocean currents that greatly influence Earth’s climate, says

In recent years, the data show it is weakening. But what does this mean?

“If this system of currents significantly slows down, this could change weather patterns in the tropics, with a detrimental effect on crop yields,” said Spencer Jones, a visiting assistant professor in the Department of Oceanography at Texas A&M University.

The article says iodine’s ‘catalytic role in particle formation enhances its effects in the atmosphere wherever it goes, whether that role is eliminating protective ozone molecules or increasing cloud cover.’ But it’s not clear why this claim would be correct: ‘As sea ice melts in the Arctic, more iodine can enter the atmosphere, increase cloud cover and enhance warming effects on the region.’ Effects of cloud cover differ between high and low cloud, for example.
– – –
An international team led by CU Boulder researchers has cracked the chemical code driving the formation of iodine particles in the atmosphere, revealing how the element contributes to increased cloud cover and depletes molecules in the Earth’s protective ozone layer, says

The research, conducted at the world’s largest particle physics laboratory, the European Organization for Nuclear Research (CERN), was published today in the journal Nature Chemistry.

It’s the first time that any experiment in the world has demonstrated the mechanism for how the gas-phase form of iodine—known as iodic acid—forms, and suggests it has an significant role in atmospheric particle formation.

The pretentious-sounding ‘Global Carbon Project science team’ (80 names) confirms the fairly obvious: the world is using at least as much fuel power as ever. A recent stat from Goldman Sachs’ Jeff Currie: ‘$3.8 Trillion of Investment in Renewables Moved Fossil Fuels from 82% to 81% of Overall Energy Consumption’ in 10 Years. More misery for climate obsessives. No sign of fear of climate retribution to be seen in the data.

Global carbon [dioxide] emissions in 2022 remain at record levels — with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team.

If current emissions levels persist, there is now a 50% chance that global warming of 1.5°C will be exceeded in nine years, claims Science Daily.

The new report projects total global CO2 emissions of 40.6 billion tonnes (GtCO2) in 2022.

In this new version, the idea that the famous body was only found due to recent warming after being under ice continuously for over 5000 years gets buried, so to speak. The sting in the tail is this: ‘the researchers also found evidence suggesting that Ötzi had not died where he was found in the gully — instead, he had been transported down the mountain by natural environmental processes’. If, as they say, he ‘had melted out of the ice many times’, those times must have occurred at various higher levels, suggesting greater warming then than we (so far) see today. This poses an awkward question or two for prevalent climate theories.
– – –
A small team of researchers affiliated with institutions in Norway, Sweden and Austria, has found evidence that suggests a flaw in the original story of how Ötzi (the Iceman) remained preserved for so long, says

In their paper published in the journal The Holocene, the group details what they describe as a more plausible explanation.

In 1991, a couple of German hikers came upon the remains of a man frozen in the ice in the Ötztal Alps. Testing of the remains showed the man to be from approximately 5,300 years ago.


It’s called ‘an investment blueprint for greening the global economy’, but means digging up ever more of the planet to find metals, minerals etc. with machinery mostly powered by the dreaded (by climate obsessives) fossil fuels. The imagined benefit is impossible to quantify – just pay up. Every year.

Developing and emerging countries—excluding China—need investments well beyond $2 trillion annually by 2030 if the world is to stop the global warming juggernaut and cope with its impacts, according to a UN-backed report released Tuesday. reporting.

A trillion dollars should come from rich countries, investors and multilateral development banks, said the analysis commissioned by Britain and Egypt, hosts respectively of the 2021 UN climate summit in Glasgow and this week’s COP27 event in Sharm el-Sheikh.

The rest of the money—about $1.4 trillion—must originate domestically from private and public sources, said the report.


Here’s a recent report, posting a video from 2014 saying the glaciers could be gone by 2020. The report itself, headlined ‘Mount Kilimanjaro’s Glaciers Estimated to be Gone by 2030’, says: ‘In 2006, National Geographic News published some stunning satellite images of Africa, courtesy of United Nations Environment Program. One of the images shows the glacial retreat occurring on Mount Kilimanjaro between 1976 and 2006. Earlier predictions of the glaciers disappearing by 2020 were obviously incorrect.’ (Al Gore was in the 2020 camp).
The next line is interesting: ‘Glacial retreat is attributed to lower precipitation, and not global warming.’ No research is quoted to support that statement, but this journal article says: ‘During the last 120 years, annual precipitation on Mount Kilimanjaro (Tanzania) has decreased by 600–1200 mm (Hemp, 2005a)’. UNESCO pushes the usual CO2 climate theory and hazards another prediction, much more cautious now, as COP27 is about to start.

Glaciers at many UNESCO World Heritage sites including Yellowstone and Kilimanjaro National Park will likely vanish by 2050, the UN agency warned Thursday, urging leaders to act fast to save the rest, reports

The warning followed a study of 18,600 glaciers at 50 World Heritage sites—covering around 66,000 square kilometres (25,000 square miles)—which found glaciers at a third of the sites were “condemned to disappear”.

The study “shows these glaciers have been retreating at an accelerated rate since 2000 due to CO2 emissions, which are warming temperatures”, UNESCO said.

The researchers say ‘climate models often differ on the precise degree of future warming, largely due to their representation of clouds.’ For decades we’ve been told to believe variations in carbon dioxide are the key to any future warming, but climate model forecasts have been unable to deliver the hoped-for precision. Predicting future cloud variations looks like a tall order.

Quick Summary

— Study adds a missing piece to the climate science puzzle of simulating clouds.
— Lightness of water vapor influences the amount of low clouds.
— Some leading climate models don’t include this effect.
— Including vapor buoyancy into climate models helps improve climate forecasting.

Clouds are notoriously hard to pin down, especially in climate science, says UC Davis.

A study from the University of California, Davis, and published in the journal Nature Geoscience shows that air temperature and cloud cover are strongly influenced by the buoyancy effect of water vapor, an effect currently neglected in some leading global climate models.
