Scientists continue to assert CO2-induced global greening will continue unabated in the 21st century…just as it has since the 1980s. As Earth’s surface becomes greener, it becomes cooler, offsetting much of the projected warming.
Satellite observations affirm the planet has become much greener over the last 4 decades, and this greening trend is largely attributed to the rise in CO2 concentrations (Zhu et al., 2016, Winkler et al., 2019, Chen et al., 2019).
Further, “nearly all” climate models “project continuous greening of the planet during the 21st century” (Wu et al., 2022).
Greening-induced increases in evapotranspiration lead, in turn, to an increase in the global cloud cover. Increases in cloud cover reduce incoming solar radiation. A decline in incoming solar radiation cools the surface.
So rising CO2 concentrations ultimately contribute to global-scale greening, and, consequently, to a surface cooling that offsets warming projections.

By how much does CO2-induced greening counteract future warming as it cools the surface?
Another group of scientists (Alkama et al., 2022) quantifies the estimates at -0.71°C of CO2-induced greening/cooling by 2100.
Probably because it doesn’t advance the anti-fossil fuel energy agenda, Alkama and colleagues point out that the cooling effects of CO2-induced global greening “are largely ignored in climate treaties”.

So, to summarize:
- CO2-induced global greening has been detected since the 1980s.
- Models say this greening will continue in the 21st century.
- Greening leads to land surface cooling.
- By 2100, high CO2 emissions will offset warming by cooling the Earth’s surface by as much as 0.71°C.

Nature organises itself always around the maximum possible in all dimensions, as a consequence it will stabelise itself around an optimum as all dimensions are inter connected. In other words too complicated for any model, sorry climate “scientists”.
WE will be taken over by triffids! We’re doomed!
Tja det er vel vanndampen fra oppvarmet hav som fører til denne effekten, mer skyer som kjøler ned kloden.

NONSENSE WILD GUESS PREDICTIONS of 78 years in the future.
Nonsense because humans have NEVER demonstrated any ability to predict the future climate, so when one reads ywt another prediction, one knows the author is a science fraud.
There is no evidence adding more CO2 emissions into the atmosphere will cause global cooling. There is decent evidence CO2 is a greenhouse gas and adding more greenhouse gases will cause some reduction in Earth’s ability to cool itself.
There is no evidence man made CO2 has ever had more than a mild harmless global a warming effect, and the next +100 ppm of CO2 added to the atmosphere should have an even smaller warming effect than the past +100 ppm of CO2 added to the atmosphere (for which the precise amount of global warming is not known, but it certainly was not harmful in any way. I would say the last +100 ppm of CO2 was beneficial, and so will be the next +100 ppm of CO2.
CO2 greening-cooling – that’s geoengineering that I fully support!
