Difference between the temperature responses in simulations with disabled sea ice changes relative to the active ice. Upper plots Annual mean surface air temperature anomalies (4 × CO2 − 1 × CO2) in zero ice relative to active ice (ΔTz − ΔTa) (a); and in prescribed ice relative to active ice treatment (ΔTp − ΔTa) (c). Anomalies shown are statistically significant at the 95 % confidence level. Lower plots zonal annual mean surface air temperature anomalies: 2 × CO2 − 1 × CO2 (yellow), 4 × CO2 − 1 × CO2 (orange), 6 × CO2 − 1 × CO2 (red) and 8 × CO2 − 1 × CO2 (brown) in zero ice relative to active ice simulations (ΔTz − ΔTa) (c) and in prescribed ice relative to active ice simulations (ΔTp − ΔTa) (d). Standard errors (2σ-values) are indicated with grey shading
