High CO2 levels can destabilize marine layer clouds, triggering spike in global warming

Feb. 25, 2019 – At high enough atmospheric carbon dioxide (CO2) concentrations, Earth could reach a tipping point where marine stratus clouds become unstable and disappear, triggering a spike in global warming, according to a new modeling study. This event—which could raise surface temperatures by about 8 Kelvin (14 degrees Fahrenheit) globally—may occur at CO2 […]
