Another New Study Finds Rising CO2 Enhances Planetary Greening And Reduces Drought Risk
By Kenneth Richard on 12. August 2024

“…elevated CO2 concentrations not only boosted vegetation growth through the fertilizer effect but also indirectly enhanced water availability [reducing drought risk] by improving water use efficiency.” – Song et al., 2024
One of the more commonly-stated concerns linked to “global warming” is that sweltering heat will parch the terrestrial landscape (browning), limit vegetation growth, and foment water shortages – even widespread drought.

However, a new study suggests the Earth’s rising CO2 concentration has the exact opposite effect in the real world.

In their extensive trend analysis spanning the last few decades, the scientists determined elevated CO2 was the single most “dominant driver” (accounting for 45% of the correlation) when assessing the link between reducing vegetation water demand and improved water use efficiency.

Compared to CO2, temperature and precipitation, for example, play a far less significant role (10-11% of the correlation) in influencing the trend in improved vegetation growth and water use efficiency.

Rain. Uptake by plants. Evaporation and transpiration. New clouds, rain downwind along the dominant wind pattern. Lather, rinse repeat. Those water molecules are playing leapfrog along dominant air circulation pattern directions. No plants, and the cycle is interrupted, the water runs off, there is no transpiration (no plants or only succulents), and only evaporation from rivers and reservoirs (natural or manmade). It's the basic hydrologic cycle.
