Even without any genetic adaptations (probably?) the world is "greening" due to increased CO2: https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fertiliz

  Lands with soil that support it are greening. Desertification is a continuing issue and typically do not green without human assistance.

    That's not what the data says. The total leaf area has increased by 25 to 30%. And there has been no drop in global precipitation.

      Err, "the data" [1] doesn't talk about increases | decreases in total land area with vegetation, the data talks about increases in green leaf area within already established areas of vegetation. ie. Your data and the prior comment aren't necc. in conflict. [1] https://www.nature.com/articles/nclimate3004 https://www.nature.com/articles/nclimate3004 We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). The global vegetated area is [2]: About 85 percent of Earth’s ice-free lands is covered by vegetation. The area covered by all the green leaves on Earth is equal to, on average, 32 percent of Earth’s total surface area - oceans, lands and permanent ice sheets combined.
