The Many Benefits of Rising Atmospheric CO2 — An Introduction

From MasterResource

By Craig D. Idso — April 6, 2022

Dr. Craig Idso, Chairman of the Center for the Study of Carbon Dioxide and Global Change, and a new principal at MasterResource, invites readers to join him in a new series of articles discussing the many ways in which rising atmospheric carbon dioxide benefits humanity and nature.

Atmospheric carbon dioxide: you can’t see, hear, smell or taste it. But it’s there—all around us—and it’s crucial for life. Composed of one carbon and two oxygen atoms, this simple molecule serves as the primary raw material out of which plants construct their tissues, which in turn provide the materials out of which animals construct theirs. Knowledge of the key life-giving and life-sustaining role played by carbon dioxide, or CO2, is so well established, in fact, that humans—and all the rest of the biosphere—are described in the most basic of terms as carbon-based lifeforms. We simply could not and would not exist without it.

Ironically, far too many demonize and falsely label this important atmospheric trace gas a pollutant. Nothing could be further from the truth. Instead of being shunned like the plague, the ongoing rise in CO2 should be welcomed with open arms.

How do I know this?

During the past three decades of my professional career I have performed countless hours of research, conducted multiple experiments, published a series of professional journal articles, written several books, created videos and feature-length documentaries, and authored thousands of commentary articles exploring the effects of CO2 on the biosphere (much of that work can be found at my CO2 Science website, www.co2science.org). In all those activities I have come to know that, far from being a pollutant, this colorless, odorless, tasteless and invisible gas benefits the biosphere in a multitude of ways. And I want to share that knowledge with you!

To accomplish this objective, over the next several months I will be publishing a series of articles describing several key benefits atmospheric CO2 enrichment provides to both humanity and nature. The articles will explore topics such as the effects of CO2 on plant growth and water use efficiency, a CO2-induced greening of the planet, the monetary benefits of rising CO2 on crop yields, and much, much more. Look for the postings at a rate of about two per month.

Sadly, most of the population remains woefully unaware of the many positive impacts of CO2 on the biosphere. This is no surprise, considering the constant and steady stream of misinformation our society endures from sources dedicated to demeaning and defaming CO2. What is more, world governments, non-governmental organizations, international agencies, societal think tanks, and even respectable scientific organizations attempting to assess the potential consequences of increasing atmospheric CO2 concentrations have spent hundreds of millions of dollars writing and promoting large reports about it.

Yet, these endeavors have failed miserably because they have neglected to evaluate or even acknowledge the manifold real and measurable benefits of the ongoing rise in the air’s CO2 content.  As a result, many important and positive impacts of atmospheric CO2 enrichment remain underappreciated and largely ignored in the debate over what to do, or not do, about anthropogenic CO2 emissions. And that omission does not bode well for policy decisions.

I hope you will join me on this informative journey as we explore the many benefits of CO2 and I hope you will share what you read and learn with others. Societal change occurs as individuals become informed one by one. Together we can help make that happen!

Every time there is combustion of fossil fuels two types of molecules are formed. H2O and CO2. Look at the tail pipe of a vehicle and notice the water dripping out. So freshwater is continually being made.

There are other molecules being produced but those two are life giving.

As a Policeman of 35 years service I had to investigate a number of suicides where people connect a hose pipe from the exhaust pipe to inside of their car. Switching on their engine it does not take long before the occupants die. On recovering their bodies a post mortem is then conducted by the local Government Medical Officer and as the investigating Police Officer I have to be present. It is quite noticeable that the person who has died from the effects of carbon MONOXIDE their internal organs turn a very noticeable scarlet color. Exhaust fumes from a motor car, in addition to H2.0 is CARBON MONOXIDE, not carbon dioxide.
Now in my career as a Policeman I have had to direct traffic in the city of Sydney on very heavy “peak hour” times with lots of carbon monoxide being exhausted and of course I would have to inhale it, so why did I and thousands of other Police directing traffic and pedestrians fail to die also? The answer in part is the dilution of the gases but more precisely the exhaust gases break up on cooling. Carbon separates from its oxygen molecule which forms with the normal O2 in the air to form ozone, which is relatively harmless to humans and the carbon become visible and settles around the city to make it look grimy. If it did not do this everyone who goes into the cities would be dead. Leon Warren, retired Inspector of NSW Police.

Tom – you missed the point. The deaths I was in charge of were examined by very experienced professional medical officers who pronounced the cause of death was carbon monoxide poisoning. Carbon dioxide was not mentioned in any of their reports.
Today in New South Wales the Department of Primary Industries who monitor environmental pollution in this state reports that the ozone levels are between 17 to 20 parts, Anything under 33 is considered very good. Incidentally the DPI does not measure caron dioxide as it is not considered a pollutant.

Carbon monoxide is formed from incomplete combustion. CO2 is the major (>99%) carbon containing product from combustion of fossil fuels .
Carbon monoxide is emitted in very low concentrations from the tailpipes of modern automobiles because of catalytic converters, which almost completely combust any remaining hydrocarbons and CO. In a sealed garage, all kinds of bad things can happen.

CO2 does not react with oxygen to make ozone. Ozone in the troposphere is formed from photocatalytic reaction of NOx and oxygen. There are also some other photo-reactions involving hydrocarbons and oxygen that can make ozone.

Further, ozone is very damaging to the lungs and one should avoid breathing it.

Hi Scissor – According to texts I have read a single atom of oxygen is unstable and will form with the two atoms of oxygen found in the atmosphere to form O3 or. as it is called – ozone. There are other ways ozone could form.
Yes ozone is very damaging to the lungs, so is oxygen and that is why when a hospital or ambulance is administering oxygen to a patient you will find on the oxygen bottle that it contains up to 10% CO2. It will also combine with other substances readily, such as iron to form rust,.
As mentioned above ozone is measured by the Department of Primary Industries as a pollutant,
The NSW Department of Primary Industries and Environment publishes hourly reports on air quality on oeh,airquality@environment,nsw.gov.au.

Yes, an O atom will combine with an O2 molecule to make ozone. It takes energy to liberate the O atom and that comes from UV light from the sun during daytime.

Normally, oxygen used in a hospital in pure oxygen. Sometimes CO2 is added in order to stimulate the breathing response by lowering blood’s pH. It really doesn’t have anything to do with preventing damage from O2.

Electric discharges (lightning) also create ozone in high enough concentrations to be smelled during thunderstorms with, of course, negligible damage to the lungs. Chemically reactive ozone is useful in reducing pollution and sanitizing areas. It can be used in swimming pools to replace chlorine (which is also, in high concentrations, rather hard on the lungs.)

Leon Warren is (hopefully) a well respected and honorable law enforcement officer with a long history of service to society. However he is woefully mistaken, nay even ignorant of essential facts of physics and chemistry. In addition, he appears to prefer an appeal to “authority” instead of doing some basic fact finding on how the chemistry of combustion works.

Combustion of an hydrocarbon adds oxygen to said fuel, and results in carbon dioxide and water vapor – period – when complete combustion occurs. In fact humans and all animals are internal combustion engines! We burn hydrocarbon fuel by combining it with oxygen and the result is carbon dioxide and water vapor. Like our mechanical engines, we too do not produce 100% complete combustion, and indeed we exhaust various “pollutants” in our breath in addition to the primary products of combustion, including some carbon monoxide!

In fact gas stoves, and fireplaces emit CO2 and CO as well as neither has 100% complete combustion.

https://www.energy.gov/eere/vehicles/fact-861-february-23-2015-idle-fuel-consumption-selected-gasoline-and-diesel-vehicles

In the above link, scroll down to the table, showing various sources and their fuel burn and the ppmv of their carbon monoxide emission. (ppmv stands for parts per million by volume)

Notice that small and medium sized cars burn 0.16 to 0.39 gallons per hour (3.78 liters per US gallon) of petrol or octane at idle. Also notice that a car fitted with a catalytic converter emits less than 1,000 ppmv of carbon monoxide, whilst a home fireplace emits 5,000 ppmv of carbon monoxide!

A petrol car’s engine burns a form of octane, which is C8H18. The chemistry of complete combustion is as follows:

http://earthguide.ucsd.edu/eoc/special_topics/teach/sp_climate_change/p_burning_gasoline.html.

To simplify the math involved for those not versed with simple chemistry nomenclature, the following shows the values reduced from molar to mass numbers:

Average between small and medium sized engines at idle
0.275 gallons per hour burned – which is

1040 grams of octane/hr PLUS
6347 grams of oxygen consumed per hour
which yields
3210 grams of CO2/hr PLUS
1477 grams of water vapor/hr

This represents 100% complete combustion, however no such thing exists practically. Given the table above showing catalyst equipped cars emit 1000 ppmv at idle, this means that
4687 grams x 1000 / 1000000 = 4.687 grams of carbon monoxide are emitted and the product of CO2 and H20 are reduced by this much.

So Leon’s statement “Exhaust fumes from a motor car, in addition to H2.0 is CARBON MONOXIDE, not carbon dioxide.” is completely false and not in accord with actual physics and chemistry. The vast majority (99.9%) of the exhaust product of internal combustion engines is CO2+H20, with minor additions of CO in accord with how complete the combustion is. However it is miniscule by comparison to the primary products of combustion. (CO is 0.1% of the car’s exhaust products)

Indeed an open home fireplace emits 5x more CO than does your car’s exhaust at idle. Which is why CO poisoning can occur with faulty fireplace chimneys and flues!

Yes, CO is poisonous at high enough concentrations.
https://en.wikipedia.org/wiki/Carbon_monoxide

667 ppmv will most likely kill or maim humans with enough exposure. EPA limits are 50 ppmv for extended workplace exposure. However also in the wiki article, it is naturally produced in the body and plays a role in normal biological processes at low concentrations!

And also in the wiki page on CO, the atmospheric breakdown of CO is detailed, and yes it does contribute to ground level ozone, but not as much as NOx – both of which have been drastically reduced since the heyday of pollution back in the 1970’s. Catalytic converters on vehicles have knocked these pollutants down 30 to 50x less than they were back in those times.

But again, ozone in low concentrations, like CO has beneficial biological benefits.

Will running your car’s engine in a closed garage kill you? You bet it will if you persist. However it is via the miniscule 0.1% of the car’s exhaust being CO, and a mere 667 ppmv concentration of CO in the garage air that kills you, and I might add an insidious way to die – you simply fall unconscious after a short time before your body shuts down and dies. (insidious because most do not recognize the onset of CO poisoning – you just get sleepy and pass out) In fact the car’s engine will die also, from using up all the oxygen in the closed garage – but sadly far after the more sensitive body has expired.

However this sad fact of people dying by accident or deliberately from CO poisoning is not evidence that all the exhaust from cars is carbon monoxide!

Perhaps a quibble, but gasoline (or “petrol” as our friends across the pond(s) refer to it) is comprised MOSTLY of HEPTANE (a seven carbon chain) that has added to it so-called “octane boosters” which slow the burning of the fuel, so as to inhibit engine knock and/or detonation which can be highly destructive to internal combustion engines.

Valid quibble, however even that is incorrect.
http://chemistry.elmhurst.edu/vchembook/514gasoline.html
The combination of iso-octane and heptane is 30-50%. Then there is 20-30% each of cyclopentane and ethyl benzene.

And the “octane rating” of normal regular gasoline is 87, which corresponds to a mixture of 87% octane and 13% heptane….

However in the example I used the average number of C and H atoms for octane is about mid range for the 500 or so hydrocarbon molecules comprising gasoline, and it’s molecular weight suffice to show the combustion product relationships.

And I use petrol instead of the vernacular “gas” so as not to confuse short form gasoline with an actual gas or methane or propane, etc.

When we start using Hydrogen as a fuel to replace Natural gas condensing the resulting water vapour will produce a supply of water.

Reply to  Ben Vorlich
April 7, 2022 4:07 pm

The same amount of water vapor is produced just burning the methane that is the major feedstock for producing hydrogen in bulk. You get more energy per unit of carbon dioxide produced just using methane as the fuel, compared to hydrogen obtained chemically from the methane, or from water electrolyzed using wind or solar generated electricity. Hydrogen is a poor choice for energy storage.

The Earth needed more CO2, and so it invented people and waited until we learned to dig up and burn all the stuff that accidently got buried in rocks over the past few hundred million years.
The more of it we liberate, the better the planet treats us.

Mapping, based upon OCO-2 satellite data, show increased levels of CO2 where broadleaf vegetation is heaviest (particularly jungles and forests). This should not occur if these areas are primarily sinks that absorb CO2. It raises the possibility (if not the probability) that broadleaf vegetation emits more CO2 than it absorbs. If estimates of the human contribution of CO2 range only as high as five percent of the CO2 level, then there has to be another source or sources for ninety-five percent of the CO2. Trees, with a root system in the Earth and leaves that interact with the atmosphere would seem to be a natural pathway for carbon and oxygen to interact.

It raises the possibility (if not the probability) that broadleaf vegetation emits more CO2 than it absorbs.
I have seen this claim made here at WUWT numerous times, particularly in reference to the OCO-2 maps.
How on Earth is it even possible for a plant to emit more CO2 than it takes in? Where does the extra CO2 come from? That little bit of a claim defies the law of Mass Balance. Nobody has explained it, even throwing insults my way here for asking.
?????????
Actually, it is a fair question.
One could possibly answer like this:
It is not really the plant that emits the extra, it is the forest soils there. So where does the forest soil get its carbon from??? Well, the plants. Obviously.
So plants are net sinks, dropping what they do not release onto the forest floor, which then emit to some extent. Can the forest floor emit more carbon that it receives from the plants. Again no. If a forest floor were to emit more carbon than it got from the plants, eventually the soils would be completely depleted in carbon, and the soil would consist of just clay, sand and gravel. Because that is what a soil is after you remove all of the organic component, leaving just the mineral component.
But we know for a fact that this process never happens naturally, and has never been observed in the wild. What we do know is that long term, that soils are enhanced, acquiring an ever increasing stock of organics from the plants growing in them.

Conclusion:
Plants are net absorbers in the CO2 they take in.
Forest, woodland and prairie soils are net absorbers in the organics they get.
OCO-2 needs to map out forest emissions for a full year to get a true picture of CO2 balance. Seasonal variations in CO2 uptake and emission are known to be huge, especially in the temperate zones. To pretend that these variations do not exist is borderline delusional.

But obviously not in equal amounts. Do I really need to point that out? How does a plant grow? Where does the carbon come from to make all the cellulose and other compounds in the stems and leaves?

If it’s not obvious that plant respiration has to be substantially less than the amount of CO2 sequestered, I just can’t even. 🙂

Tropical forest has surprisingly little humic soil. Most of the carbon in the ecosystem at any time is in living plant (and animal) tissue. That’s why those rainforests are fragile – cut them down and you risk ending up with desert.

Temperate forest by contrast has deep humic soil holding a much larger percentage of the carbon in the forest ecosystem.

Yes, thankyou. Everything has to come from somewhere.

But I would say that soils eroding away—in dessert regions—do lose their carbon to the atmosphere. Throughout the American Southwest, we see scattered coal fields eroding away, with the hydrocarbons evaporating in the heat and light.

Absolutely so, and NASA showed that in the original images they published.

But that didn’t fit the narrative so they came up with the C0ck and Bull story that the OCO Sputnik couldn’t see through the clouds that always hung over the forests, or especially when the sun was up and the Sputnik could actually ‘see’ something

Hence the images we see now do not have any visible data for the big forests

It’s called ‘Lying By Omission’ and NASA are now very accomplished at doing it

Did no-one, not a single one of us, wonder how the Global Greening Sputnik could see the ground as the very prerequisite for its mission, while OCO2 couldn’t?
No-one?
Especially when OCO is looking for a ‘well mixed gas’ and the white tops of clouds should have been perfect for how it did its measurements?

So what changed for OCO Sputnik ‘tween 2015 and now?
(haha Did The Climate Change?)

Here’s what. some of what, OCO originally saw…

Another example of NASA inaccuracy is their paper entitled “Satellite Detects Human Contribution to Atmospheric CO2” which is a description of a Finnish study using OCO-2 data to map the human CO2 contribution in various countries. The map of the US clearly shows a correlation of CO2 presence with areas of increased vegetation not human activity. The same is true for China.

I think we have thousands of years of fossil fuels.
Some of the largest resources are not even used at all yet.
Others are barely used.

I do hope you mean Carbon Capture Schemes = where they bury the gas into old oil wells or wherever

Sequestration, by plants, is what Earth needs more of…##
…because… and contary to to popular belief..
Carbon Dioxide does not control weather (directly) – water does.

Also contrary: – when carbon is sequestered by plants, it is an accretion process for carbon (else there’d be completely no soil on this Earth)
But very significantly, the sequestered carbon (Lignin & Cellulose) sequesters immense amounts of water. on what would otherwise be and is falsely labelled: Dry Land

and it is that water, captured in the soil, that controls climate

## a neat trick that would help innumerable people be to make Biochar out of coal.
Gasify the stuff (as per Town Gas of the Good Olde UK Days)
Use the gas for whatever and then bury the left-over coke into farmland and all other soils.
Soak it, for a couple of weeks, in a solution/slurry of poo, liquidised food waste, paper-mill waste etc etc
Could nearly do the same with ‘waste’ plastic – gasify it, burn the gas for energy, electrikery, heating or use it for ‘chemical processes’ such as medicine and then give the left over black powder/dust/bits to farmers, gardeners and those sorts of folks.

Good to hear from the agronomy/biology sciences.
Earth’s atmosphere has evolved from billions of years of biogeochemical cycling.
Primordial Earth had an atmosphere similar to Venus.
The lifeless atmosphere of Venus did not evolve, Earth’s was transformed by life.
Except for Argon, the composition of early Earth’s atmosphere has been entirely replaced by biological Nitrogen, Oxygen, Carbon Dioxide, Methane, etc.
Water ties the geochemical components with the biological.
This is why physicists will never understand the atmosphere.

Burning fossil fuels does not cause climate change. Since 2002 the CO2 level has increased 48% of the increase from 1800 to 2002. The average global temperature reported by UAH is about the same as it was in 2002. The average of all agencies shows a temperature increase since 2002 of about 0.1 C°. All agencies report a downtrend since the El Nino peak in 2016. I wonder how much more evidence will be needed for some people to recognize that CO2 level has little, if any, influence on average global temperature.

Well, there has been a recent move to include other gasses in the bad boy category, principally Methane. My view is that there is enough questioning of CO2 being pollution because plants need it and that a bit of warming is a good thing they need something more horrificthan CO2 and Methane fits the bill.
It has taken at least 20 years for the questioning of CO2 as pollution to become noticable in some of the press. Methane may well buy another deecade or two of blaming humans for a bit of warming

Based on the 2016 NOAA report, in 2022 Earth has been greening for over 40 years. Over that period the world has been experiencing the warming part of an approximately 70-year cycle of warming and cooling. Given that UAH6 documents an approximately 0.13 C/decade warming during that upswing, what is everybody so concerned about? Other than during the recent double-Super El Nino (now falling off like a rock) the world has not warmed noticeably since the end of the 20th Century. A quarter of a century with no CO2-driven warming is not enough for CliSciFi declare an end to their catastrophic narrative?

A little fun logic and factoids to start the CO2 benefits discussion.
Photosynthesis stops at about 50ppm CO2.
Preindustrial was about 280ppm. At that level, ocean carbonate sequestration is balanced with subduction conversion back to CO2 expelled via volcanos. So the planet dies if tectonic subduction were to stop and 230ppm got sequestered.

The best ‘academic’ estimate of carbon sequestration is 310 megatons of Carbon per year, which is 1.14 E+9 of CO2. (Multiply by 44/12 atomic weight).

The atmosphere is estimated to contain 5140 trillion tons of gas, so 5.14 E+15 tons. Losing 230ppm means losing about 1E+13 tons of CO2.

Ignoring the slight mismatch and treating both numbers as simply “1”, the planet would die but for tectonic subduction in 1 E+13/1 E+9 =1 E+6 or 1 million years.

Good thing we discovered plate tectonics, or the carbon alarmists would really have something to be alarmed about and would advocate more fossil fuel use. /s

During the next glaciation period, humans (assuming CliSciFi and/or socialists don’t kill everybody) will produce the needed atmospheric CO2 for plant life to carry on and produce enough food for however many humans exist at that time. Although even then I don’t expect a universal basic income (al a Star Trek) since it has been proven to be anti-survival and, if nothing else, history proves that humans want to survive. The next few worldwide elections may prove that thesis (or not).

What’s the correct amount of atmospheric CO2? A doubling from preindustrial times at 280 ppmv to 560 ppmv would be ideal. And it will will still take a lot of work to get to that, and this is what some or most of the models are based upon, which is a doubling of CO2 from 1850 to perhaps a doubling by 2100. Bring it on!

Even if it does provide a 1 degree C increase in temps, what’s not to like about that? Far better than a 1 degree cooling, which would be catastrophic to life on the planet with going on an 8 billion population. Seems to be a very good insurance policy on keeping things alive, and at a bare minimum temperature conducive to life. It is just a blip in geological time when some future extended ice age sees CO2 dropping to 150 ppmv and below, and a lot of life ceases to exist.

For the unwashed uninformed folks that I sometimes interact with, ask them to imagine a box full of 10,000 ping pong balls and 3 of them were CO2 ping pong balls. Now we have added another single ping pong ball out of 10,000, making 4 CO2 ping pong balls out of a total of 10,000. And this is a climate emergency over that? The physics for that doesn’t even add up.

Just because the good Earth is close to going extinct at the peak of every glacial maximum when CO2 drops to 180 ppmv, (and below 150 becomes a problem) a doubling from 280 ppmv in an interglacial to 560 ppmv is still a trace atmospheric gas. Doubling next to zero, is still near zero. I didn’t think the fuss over negligible increases in a trace atmospheric gas essential to life would last this long in popular culture. I suppose the old saying about telling a big enough lie for long enough, has some merit.

You somehow believe that my recognition of the many many trillions invested in green energy derivative funds can only be because some genetic ancestor did some particular thing; I can’t see what is in front of my eyes otherwise?

There is also the case, if what I’ve read is correct, that a great part of those many trillions (through probably not a majority part) is comprised of state pension funds. ‘state’ in this context means not only the 50 U.S. states but ‘the state’ which can be any government anywhere.

States obviously have a lot of power to ensure that those investment funds do well as the state controls the laws and regulations that give the funds such a huge advantage. It may well also be true that there are ‘state’ funds other than civil servant pensions that are part of the mix.

I’ve been posting this for more than a decade:
Photosynthesis: Plants/Plankton turning Sunlight/CO2/H2O into Food/O2; neither animal nor blade of grass would exist, absent CO2. More CO2 helps plants resist drought/damage/disease, extends growing seasons, lets plants move higher in altitude & Latitudes, shrinks deserts & reduces the spread of fire, plants using & retaining H2O more efficiently. As CO2 rises, photosynthesis flourishes & plants take in more CO2, sparking more growth, photosynthesis & CO2 uptake. Rising temperatures also extend growing seasons, help babies survive, increase net rainfall & save lives.
This Cradle of Life is greener, more fertile & life sustaining than it was 200 years ago. Because adding food to the base of the food-chain helps all of Nature.

Of course it is always possible to have too much of a good thing – too much carbon dioxide, too much oxygen, too much water, too much beer, too much food, etc etc.

With respect to atmospheric CO2 concentration, the warmunists declared our current low 400s ppm “too much”. But they never any provide empirical proof that such is so … they merely prattle on about the rate of change in CO2 and their claimed, but wholly unproven, assertion of so-called “climate CO2 sensitivity”.

What we do know is that human health effects due to excessive CO2 concentrations do not begin to present until around 20 thousand ppm, and humans can tolerate much higher concentrations than that without permanent tissue damage or death – into the hundreds of thousands of ppm.

Plants can also tolerate far higher concentrations than 400 ppm, as any nursery operator can attest. So the only “problem” is so called global warming . However we know from studies of ancient biological evidence in the form of geologic material composition and “fossil fuels” and various climate proxies that in earlier ages, the CO2 concentrations were far higher than today, yet the earth did not ever experience “runaway” or catastrophic warming, and that the biosphere adapted quite effectively to both warmer climates and higher CO2 concentrations, the latter being NOT the cause of the former but rather a product of the former.

Carbon dioxide is also underappreciated as a heat transfer aid. How so?

The atmosphere operates far more powerfully as the compressible working fluid of its own heat engine operation than as a static radiative absorption and emission layer experienced at the surface looking toward space. An incrementally stronger radiative coupling of the lower atmosphere to the surface helps transfer energy – especially the latent energy of water vapor – to the working fluid at the compressed “hot” end of the cycle, and the incrementally stronger radiating effectiveness of the upper atmosphere to space helps reject heat at the expanded “cold” end. The mass flow rates and altitudes achieved in the overturning circulation will be whatever the heat engine cycle produces in response to the conditions experienced by the working fluid at the “hot” and “cold” ends.

One must remember that the conceptual “emitter” of longwave energy to space which keeps things in balance down here is not the surface of land and ocean over most of the planet. It is higher up, and it is not fixed in altitude or output over each element of surface area.

Years ago, in Mechanical Engineering magazine, someone wrote a letter to the editor when the CO2 warming claims began to be actively discussed in the late 1990’s or early 2000’s. The writer described CO2 as a “helper molecule” – i.e., helping with what water vapor does as a component of the working fluid. I wish I had kept a copy, because I think I understand better now what he must have been getting at.

Thank-you Dr Idso for this article and your excellent and important work on the benefits of CO2.

Perhaps the most egregious falsehood of the climate catastrophe narrative is not false things that are said (such as nonsense about impending catastrophe or ridiculously high CO2 “sensitivity”) but rather – true things that are not said.

In climate we need the truth, the whole truth and nothing but the truth.

And the most important truth that it not being spoken, that is being actively suppressed, is precisely the benefits of CO2 to plants and to the whole ecosystem and biosphere. An incredible 30% enhancement in the efficiency of photosynthesis has been measured as a – hugely beneficial – consequence of increased CO2. This has been robustly demonstrated NOT to be an indirect consequence of warming or wetness but as a direct enhancement of photosynthesis at the level of the leaf, the stomata and the cell.

https://ptolemy2.wordpress.com/2020/10/04/co2-fertilisation-and-the-greening-of-the-sahara/

Also – perhaps counterintuitively – increased CO2 enhances oxygenation of (“ventilates”) the deep ocean:
