Thanks for presenting this "contrarian" view about desertification. I was surprised to learn about global greening due to rising CO2.

Carbon Dioxide Fertilization Greening Earth, Study Finds - https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fer...

While it sounds like good news for the ecology, I think the overall destructive effects of human activity on the global environment far outweighs any accidentally beneficial effect of rising CO2. Celebrating it as "global greening" seems to be just as much of an oversimplification as the fear-mongering of desertification.

Well... plants breathe CO2, so. :)

I actually wonder if, in 100 years, how the oxygen content will increase if this greening continues?

It'd be wild to consider a 27% oxygen environment on Earth in the year 2100. Which would also cause problems of its own, as I imagine you might have a higher risk of fires, since you have more available oxygen.
