A just-released study has debunked the narrative that increased human-caused carbon dioxide is causing so-called ‘global warming.’
A major new study has debunked the narrative that increased carbon dioxide in the atmosphere from human activity is causing so-called “global warming.” [emphasis, links added]
The study, published in Science Direct [archived here], confirms what “climate scientists” should have told the public a long time ago.
The warming effect of carbon dioxide in the atmosphere is naturally limited, according to the new study. That limit was reached decades ago.
The study found that carbon dioxide (CO2) emissions have zero impact on the Earth’s global temperatures.
Even if we dug up all the world’s coal and extracted all the world’s oil and burned it in one giant pyre, the CO2 emissions wouldn’t heat the planet.
The findings of this study directly conflict with the globalist “climate crisis” narrative being promoted by the United Nations-funded “science” community.
Even the taxpayer-funded National Aeronautics and Space Administration (NASA) continues to push these “global warming claims.”
In a statement explaining “climate change” to children, NASA presents the “greenhouse effect” as a simple cause-and-effect:
How are humans impacting the greenhouse effect?
Human activities are changing Earth’s natural greenhouse effect. Burning fossil fuels like coal and oil puts more CO2 into our atmosphere.
NASA has observed increases in the amount of CO2 and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth’s atmosphere to trap more and more heat. This causes Earth to warm up.
What NASA doesn’t mention is that CO2 doesn’t cause Earth to warm up infinitely.
The three Polish scientists at the Military University of Technology in Warsaw who authored this latest study were following in the footsteps of other scientists who drew similar conclusions in their research, published in the last few years.
As Slay News reported, one recent study found that the atmosphere becomes saturated with CO2.
Much like a sponge, it can only hold so much, meaning CO2 cannot increase temperatures anymore as the saturation point was reached a long time ago.
The corporate media has refused to report on these studies, however.
All of these studies follow the same underlying concept.
The latest study uses a hypothetical concept of a fire inside a greenhouse that is steadily emitting heat.
The greenhouse grows increasingly hotter but at some point, the heat will start to dissipate, and the temperature inside levels off.
The glass walls and ceiling can contain only so much heat before they start emitting it to the outside.
The case of CO2 in the atmosphere is very similar.
It can act as a “greenhouse” gas but all the CO2 together can only contain so much heat, much like the hypothetical greenhouse.
CO2 Coalition explains:
“The warming effect of each molecule of CO2 declines as [CO2’s overall] concentration increases.”
Once the overall limit has been reached, adding more CO2 has no more impact.
Interestingly, the greenhouse limit may have been reached before the first coal-fired factory was even built.
The Polish scientists assert, based on their findings, that there is “currently a multiple exceedance of the saturation mass for CO2 in the Earth’s atmosphere.”
According to the study, we already reached the point, long ago, where CO2 lost its effectiveness in warming the planet.
Scientists at McGill University made the same point last year:
Transmission in the CO2 band center is unchanged by increased CO2 as the absorption is already saturated.
By “already saturated,” they meant that absorption has been saturated for centuries—since the “preindustrial age,” in fact.
The level of CO2 in the atmosphere is slightly above 400 ppm today.
According to Prof. Dieter Schildknecht of Bielefeld University, Germany, CO2’s saturation level is just 300 ppm, a level that was probably reached around 1950, as the graph below illustrates.
Based on previous research, Schildknecht writes that beyond this level, emissions caused by human activity have no significant effect on CO2’s greenhouse properties.
According to National Geographic, however, CO2 levels reaching 400 ppm was a “climate milestone”:
The last time the concentration of Earth’s main greenhouse gas reached this mark, horses and camels lived in the high Arctic.
Seas were at least 9.1 meters (30 feet higher)—at a level that today would inundate major cities around the world.
National Geographic doesn’t provide any evidence to prove these remarkable assertions, however.
Yet, it does admit that “the last time the concentration of CO2 was as high as 400 ppm was probably in the Pliocene Epoch…”
It then attempts to bolster the case by claiming:
But tens of millions of years ago, CO2 must have been much higher than it is now—there’s no other way to explain how warm Earth was then.
There are actually many ways, like changes in solar activity, to explain why Earth may have been warmer and colder in the past.
But what National Geographic and climate alarmists are attempting to promote is the fear of the future unknown:
The planet was about 2 to 3 degrees Celsius (3.6 to 5.4 degrees Fahrenheit) warmer.
But Earth then was in the final stage of a prolonged greenhouse epoch, and CO2 concentrations were on their way down.
However, the May 2013 reading represented something different.
This time, 400 ppm was a milepost on a far more rapid uphill climb toward an uncertain climate future.
Parents may want to check how much of their children’s science textbooks are filled with fearmongering as opposed to proper physics.
Explanations of how greenhouses and greenhouse gases work are key to understanding the facts about the Earth’s climate.
