This is mainly due to the rise in greenhouse gases (CO2, CH4, N2O, O3, halocarbons, stratospheric water vapour from CH4) by a total of +3.06 Watt/m2. Other drivers include black carbon (+0.1 Watt/m2) and solar irradiance – the latter during the first half of the 20th century (+0.12 Watt/m2).
Warming was in part mitigated by emitted sulphur aerosols (direct effects…
