Record #119672:

Deriving global climate sensitivity from palaeoclimate reconstructions / Martin I. Hoffert, Curt Covey.

Title: Deriving global climate sensitivity from palaeoclimate reconstructions / Martin I. Hoffert, Curt Covey.
Author(s): Hoffert, Martin I.
Covey, Curt.
Date: 1992.
In: Nature. (1992.), Vol. 360(6404) (1992)
Abstract: Climate sensitivity is defined as equilibrium surface temperature increase for CO₂ doubling. Alternative to model-based estimates is available from reconstruction of past climates, which implicitly includes cloud feedback. Here, sensitivity of two palaeoclimates is retrieved, one colder and one warmer than at present, by independently reconstructing equilibrium surface temperature change and radiative forcing. Results yield range that is comparable with estimates from GCMs and inferences from recent temperature observations and ocean models.
