New paper with @piersforster now out in @NatureClimate - Energy budget constraints on historical radiative forcing nature.com/articles/s4155…
Provides a top down energy budget constraint on historical radiative forcing of 2.3 (1.7 to 3.0) [5-95%] Wm-2. Thread: [1/n]

Radiative forcing is a fundamental quantity for understanding the drivers of climate change, yet significant uncertainty remains in our quantification & model representation of it. For example see any paper that includes @gunnarmy including this epic journals.ametsoc.org/doi/abs/10.117… [2/n]
What we do is combine measurements of historical temperature change dT & Earths heat uptake dN alongside model reconstructions of Earth’s radiative response Y. Constrains historical forcing F via energy budget eqn F=dN+YdT. Like Otto etal nature.com/articles/ngeo1… in reverse [3/n]
