Yeah, but it's not just the CO2/temperatures alone. Heatwaves, heavy rainfalls, droughts, hailstorms and other extreme weather events can devastate crops and disrupt agricultural systems. Don't forget that overshoot is our problem, and climate change is just one of its symptoms. The loss of biodiversity, particularly pollinators like bees, can threaten crop yields. Increased pests and diseases. Soil erosion. Fires. Etc. etc. https://skepticalscience.com/co2-plant-food-advanced.htm A specific plant’s response to excess CO2 is sensitive to a variety of factors, including but not limited to: age, genetic variations, functional types, time of year, atmospheric composition, competing plants, disease and pest opportunities, moisture content, nutrient availability, temperature, and sunlight availability. The continued increase of CO2 will represent a powerful forcing agent for a wide variety of changes critical to the success of many plants, affecting natural ecosystems and with large implications for global food production. The global increase of CO2 is thus a grand biological experiment, with countless complications that make the net effect of this increase very difficult to predict with any appreciable level of detail. |
