What will happen when to much carbon dioxide is released into the atmosphere is there a limit that the existing atmosphere cannot sustain life because of to much carbon dioxide?

Excessive carbon dioxide in the atmosphere can lead to enhanced greenhouse effects, resulting in global warming and significant climate change. While the atmosphere can currently tolerate elevated CO2 levels, there is a threshold beyond which severe ecological disruptions and health risks may occur, potentially rendering environments uninhabitable. If CO2 levels rise too high, it can lead to ocean acidification, habitat loss, and compromised food systems, threatening biodiversity and human survival. Ultimately, while there isn't a specific CO2 limit, continued emissions pose serious risks to life on Earth.
