It is possible to construct a clear Fact about changes in global mean surface temperature changes and the associated uncertainties. (judithcurry.com)
The strength of the radiative heat loss to space per unit warming of global mean surface temperature is a key quantity of interest, as usual. (gfdl.noaa.gov)
The projected change in global mean surface air temperature will likely be in the range 0.3 — 0.7 °C (medium confidence). (fabiusmaximus.com)
