Title: Decomposing climate sensitivity: A statistical approach for a spatially heterogeneous planet
Authors: J Isaac Miller - University of Missouri (United States) [presenting]
Abstract: Climate sensitivity, which relates anthropogenic forcings to global mean temperature, is defined by a constant parameter from an energy balance model for the Earth and identified by the requirement that net heat flux must be zero in equilibrium. Although net heat flux must sum to zero for the planet, the summands may consist of spatially heterogeneous non-zero changes in net heat flux and changes in the spatial distribution of temperature anomalies. A statistical methodology is proposed to estimate the heterogeneity, and a statistical test is developed that supports its existence using HadCRUT4 and GISS data.
