The average temperature above equilibrium during the 30 year warm phase will be +2 / π
x 0.155 °C which with ECS = 1.5 °C results in BNO (S) requiring 120ZJ from storage to maintain the 1985 - 2014 warm phase and the
accumulating storage of an identical
amount during the cool phases 1925 - 84 and 2015 - 44.
