WebFeb 11, 2024 · Charney estimated climate sensitivity to be 3°C (5.4 °F), give or take 1.5°C (2.7°F). Without knowing the true climate warming response to increased CO2, essentially, all climate models become a crapshoot. It is a glaring illustration of just how imprecise climate science really is. WebGCMs agree on sensitivity values in the range +1.5 to +4.5°C but cannot exclude higher values (Andronova et al. 2007).
