      Rapid adjustments occur after initial perturbation of an external climate driver (e.g., CO2) and involve changes in, e.g. atmospheric temperature, water vapour and clouds, independent of sea surface temperature changes. ...

    • A global model–measurement evaluation of particle light scattering coefficients at elevated relative humidity,
