Linear response functions

Linear response functions can be used to project sea level contributions from ocean warming and ice discharge from Greenland and Antarctica into the future.

We propose a functional form R(t) = Γ⋅t^α with positive α for Antarctic ice discharge from surface warming and negative α for other contributions (Winkelmann & Levermann, 2012).

Using response functions derived from the SeaRISE intercomparison the sea-level contribution from Antarctic basal ice-shelf melting was projected up to 2100 (Figure & Levermann et al. 2012)
