Except that all agricultural lands have increased production with increased CO2. There hasn't been any degrading of agriculture to date with the warming we've seen. And at 400ppm to 800ppm for CO2 you barely get any more greenhouse effect from this doubling, it's already nearly saturated. At most only .7C more increase which is easily manageable. Plug in 400 and 800 here, it barely changes the effect: https://climatemodels.uchicago.edu/modtran/

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.

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.

And yet the cyclonic energy on earth seems to be slightly decreasing or in stasis over the last forty years: http://tropical.atmos.colostate.edu/Realtime/index.php?arch&...

Use the drop down and pick the last option.

Cyclonic energy may show a specific trend, but it's just one aspect of the broader climate system. While cyclones might not have intensified, the multifaceted impacts on agriculture, ecosystems, and weather patterns due to increasing CO2 are undeniable. The entire picture should be considered, not just isolated metrics.

[swader999]

Ok, please continue, what are these multifaceted impacts?

[myshpa]

Increased CO2 impacts agriculture through changes in precipitation patterns, heat stress, reduced soil moisture, soil salinity, accelerated weed growth, pest and disease proliferation, pollinator disruption, shifts in crop phenology, nutrient imbalances in crops, decreased water availability, altered growing seasons, and the possibility of novel crop diseases, to name just a few.

The full range of potential impacts is vast, complex, and is a subject of ongoing research.
