If we stopped emitting CO2 into the atmosphere today, how long would it take for global warming to cease?

    If we stopped emitting carbon dioxide into the environment at this very second, we would still have to deal with the consequences of what we have put in the environment so far for another 50-200 years – AT LEAST. This table can be found on the second link cited:


    Greenhouse Gas Lifetime (Years) 100-Year GWP
    Carbon Dioxide (CO2) hundreds 1
    Methane (CH4) 12 25
    Nitrous Oxide (N2O) 114 298
    Hydrofluorocarbon-23 (CHF3) 264 14,800
    Sulphur hexafluoride (SF6) 3,200 22,800
    PFC-14 (CF4) 50,000 7,390
