Uhh... ok so does this research take into account both China and Africa has been spending $$$ billions on reversing desertification? They've been using new technology to make desert sand retain water, thus allowing certain types of trees & vegetation to grow in areas that previously couldn't sustain plant life.

Then there's the fact that China has spent over 30 years investigating how to use desalinated sea water to grow rice. Now they're able to grow rice fields in places that couldn't before.

I'm not trying to dismiss the research but to simply say that rising C02 levels have made desert land fertile seems grossly misleading.

The article makes clear that areas that aren't under the massive undesertification programs you bring up have shown the same results.

Kind of like how towns that got fluoride in the water and towns that didn't both experienced an increase in dental health during a period in which there were massive advances in dentistry and fluoride toothpaste became a thing.
