Earth System Sensitivity: a Feedback perspective

In the field of climate-change research a lot of effort is devoted to the ‘narrowing down’ of uncertainties in the estimation of Equilibrium climate sensitivity (ECS), the global mean warming as a result of an instantaneous doubling of the CO 2 concentration in the atmosphere. The present study expl...
