Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

Up in flames After recording Canada’s highest ever temperature on 29 June 2021, Lytton in British Columbia had to be evacuated as wildfires engulfed the town and destroyed most of its buildings. On balance, clouds nearer the stratosphere warm us, whereas low-lying clouds tend to cool us because their greenhouse effect is smaller.

Also missing is any realization that clouds also contribute to the greenhouse effect (roughly 25% of the total) and so whether cloud changes warm or cool depends very much on where the clouds are (high clouds have a very different effect than low clouds for instance).

At RePlanet Nederland, we are delighted that the European Commission has proposed, on December 31, 2021, to include nuclear energy in the sustainable finance taxonomy. Yet, we believe that in its current form the proposal would underachieve the goal of encouraging private investment in nuclear energy as a sustainable activity.
