Evidence that Higher [CO2] Increases Tree Growth-Sensitivity to Temperature: A Comparison of Modern and Paleo Oaks https://pmc.ncbi.nlm.nih.gov/articles/PMC6108346/ https://pmc.ncbi.nlm.nih.gov/articles/PMC6108346/ If you read above it shows that temperature sensitivity is inversely proportional to CO2 density. In other words the thinner the CO2 the more sensitive plants are to temperature swings. Higher CO2 makes the plants more resilient at higher altitudes, not to mention the long-studied effect on growth, which improves survivability for all species of plants at all altitudes.
