Peer-reviewed research shows carbon dioxide is good for the planet — is it worth it?

A number of recent scientific papers have published dramatic evidence that carbon dioxide levels are already “saturated,” meaning that no or little further warming is expected and carbon dioxide concentrations will rise.₂ levels are beneficial.

Half of human emissions are being pushed rapidly back into the biosphere, causing massive plant growth that could eliminate famine, while the rest enters a “saturated” atmosphere with minimal impact on global temperatures, scientists say. One of the papers acknowledging human involvement in rising carbon dioxide₂ Published by CO₂ “We love carbon dioxide,” the alliance said₂and so should you.

None of this work will receive mainstream coverage because it undermines the “established” climate science narrative associated with the political net-zero fantasy. But the idea that humans control the climate thermostat by releasing carbon dioxide₂Climate change, which is driving runaway temperatures, belongs to science's dark ages, when it was used to promote political goals. Yet the skeptical climate community continues to struggle to understand how many gases with warming properties behave in a chaotic, nonlinear atmosphere. Two recently published papers found that a doubling of carbon dioxide concentrations₂ Temperature increases in the atmosphere are minimal. The calculated numbers can be considered to be within a margin of error and, based on past observational evidence, do not pose a threat to Earth's climate. They also destroy the shaky scientific foundations on which Net Zero rests.

Eight Taiwanese scientists, led by Professor Wei Peng-sheng, found that climate is sensitive to rising carbon dioxide concentrations₂ At 0.3°C, atmospheric concentrations of 100 to 400 ppm are “so small that they can be ignored.” The paper is complex, studying heat transfer as a function of longitude, latitude and altitude, “as well as diffuse radiation determined by absorption bands based on wavelength, temperature and carbon dioxide vapor concentration or pressure.” What scientists are focusing on here are the narrow absorption bands within the infrared (IR) spectrum that allow “greenhouse” gases to trap heat and warm the planet. Many believe that after reaching a certain level, the gas “saturates” and loses most of its warming properties. A simple way to understand this is to observe that doubling the insulation in the attic will not absorb twice as much heat. The saturation hypothesis appears to explain how carbon dioxide₂ Temperatures have increased 10-15 times in the past without spiraling out of control, and the idea of ​​anthropogenic warming is little more than scientific cover for a cunning but fashionable extreme ecological panic.

Intergovernmental Panel on Climate Change claims climate sensitivity figures are based on CO2 doubling₂ The temperature is around 3°C. But many climate models have fueled public hysteria by using “pathways” to make larger and highly improbable estimates. The latter forms the basis of numerous “scientist-said” stories that are undoubtedly faithfully reported by the mainstream media. Scientists in Taiwan found that a 0.3°C increase in ground temperature was associated with an increase in carbon dioxide concentration from 100 ppm to 350 ppm, without any increase in carbon dioxide concentration at all.₂ Further rise from 350 ppm to 400 ppm. Current carbon dioxide levels₂ The concentration in the atmosphere is 420 ppm.

Seven Austrian scientists have also recently focused on carbon dioxide₂ and infrared spectroscopy, pointing out that doubling the gas concentration to 800 ppm in the future “shows no increase in infrared absorption of the 15u central peak.” The conclusion was that this would result in a warming of at most 0.5°C. Scientists believe climate models and their carbon dioxide₂ The impact should be corrected. “Before assigning current warming trends and climate change mechanisms to the greenhouse gas theory as a single cause,” more experimental evidence on infrared radiation should be gathered.

Recent papers on CO₂ Saturation isn't the only thing being released recently. Earlier this year, a team of Polish scientists led by Dr. Jan Kubicki provided three papers arguing that at concentrations above 400 ppm, “CO₂ The concentration no longer causes an increase in temperature”. In 2023, three scientists including Huang Yi, professor of atmosphere at McGill University, said: “Transport in CO2₂ Band center does not change with increasing CO₂ Because the absorption is already saturated. Yu Chen et al. In 2023, it was reported that CO₂ The warming effect is significantly reduced compared to pre-industrial concentrations. It is also worth noting that the effects of water vapor and clouds overlap, thus dominating the absorption of carbon dioxide.₂ Infrared band. In 2022, German physics professor Dieter Schildnecht set CO₂ Saturation is only 300 ppm.

carbon dioxide₂ The Coalition is an educational foundation that claims it provides facts, resources and information about CO’s “vital role”₂ Play in the environment. It recently published a detailed paper acknowledging that humans contribute most of the carbon dioxide₂ This has entered the atmosphere during the industrial age. The paper's subtitle is: “How human emissions can restore vital atmospheric carbon dioxide₂”. The coalition has long advocated for the role saturation plays in moderating the effects of many gases with warming properties. In his work, people often pay attention to the role played by water vapor, which accounts for about 4% of the atmosphere and contributes as much as 80% to global warming. It saturates over much of the infrared spectrum, reducing the influence of other gases in its specific band. The consortium's board of directors includes the distinguished Professor William Harper, who has long argued the merits of the saturation hypothesis, and was recently joined by Dr. John Crowther, 2022 Nobel Laureate in Physics.

carbon monoxide content₂ Values ​​were much higher in the past, and there is evidence of robust plant and animal life. Many plants evolved to thrive at higher levels than they do today, and some scientists believe this period was one of great carbon dioxide emissions₂ Exploitation. In a recently published paper, the alliance noted that higher carbon dioxide concentrations₂ The more of it in the atmosphere, the greater the pressure on physical processes to drive carbon dioxide₂ Access to ocean and vegetation.

Although readers who rely on mainstream media are largely unaware of the recent substantial “greening” of the Earth, a wealth of evidence has confirmed it. In fact, a new “green revolution” is feeding the world. Charles Taylor and Wolfram Schlenker, authors of a recent Science paper, note: “We consistently find large fertilization effects; a 1 ppm increase in CO₂ The equivalent of corn, soybean and wheat production increased by 0.4%, 0.6% and 1% respectively. Earth's severe greening can be seen in map published for the first time Donoghue/CSIRO 2015 and republished in another recent paper by CO₂ alliance. This study examines the nutritional value of plants grown under enhanced carbon dioxide conditions₂ concentration.

Maps based on satellite foliage data show that green area increased by 20-30% between 1982 and 2012 in India, Western Australia, the Sahel region and the Anatolian highlands. A paper by Chen Xin et al. 2024 found that greening has actually accelerated over the past two decades. increase in carbon dioxide₂ was found to be the main driver of positive trends in leaf area index across much of the world's land surface.
