German examine reveals that the addition of CO2 has resulted in 14% extra vegetation within the final 100 years! – Watts up with that?

Almost everyone with only a fraction of a scientific education knows that CO2 is a fertilizer for vegetation and that the 100 ppm added to our atmosphere in the last few decades favored plant growth and thus led to more greening of the continents.
However, some alarmists are still sniffing or denying this fact.
More trees (+ 7%) and vegetation (+ 14%)
In the 34th climate video, Die kalte Sonne reports on a current German study by Merbach et al., Which deals with the question of how beneficial the added CO2 was for plant growth worldwide.
The authors’ results: Global vegetation growth has increased over the past 100 years.
“The global vegetation cover increased by around 11 to 14%, of which 70% can be attributed to the increased CO2 in the atmosphere,” reports Die Kalten Sonne on the results.
Another result: “Since 1982 the tree population has increased by more than 7%”.
Crop yields will increase by up to 15% by 2050
The news is getting even better, the scientists show. Food production is expected to increase due to the increased levels of CO2:

As the above graph shows, crops like soybeans (soybeans), wheat (wheat), rice (rice), and maize (maize) will increase if CO2 levels rise to 550ppm by 2050, which is of great help in feeding the Planet represents growing population that could reach 10 billion by mid-century.
Germany: more than 30% higher crop yields since 1990
Another example is Germany: “From 1990 to 2015, the crop yields for wheat, barley, maize and potatoes in Germany rose by more than 30%, which the researchers attribute in part to the higher CO2 concentrations,” reports Die kalte Sonne.
“The authors hope that the CO2-related increase in yield will secure the production of food and animal feed and contribute to feeding the growing world population.”
The study was published in the Journal of Land Management, Food and Environment at the end of 2020.
