Almost everyone with even just a fraction of a science education knows Co2 is fertilizer to vegetation and that the added 100 or so ppm in our atmosphere over the past decades have been beneficial to plant growth and thus led to more greening of the continents.

Yet, some alarmists still sniff at this fact, or deny it.

More trees (+7%) and vegetation (+14%)

In the 34th climate video, Die kalte Sonne here reports on a recent German study by Merbach et al that looks at the question of just how beneficial the added CO2 has been to plant growth globally.

The authors' findings: Over the past 100 years, there has been increased global vegetation growth.

"The global vegetation cover increased approximately 11- 14%, of which 70% can be attributed to the increased CO2 in the atmosphere," reports Die kalte Sonne on the findings.

Another result: "Since 1982, the inventory of trees has increased more than 7%".

Crop yields will rise by up to 15% by 2050
