Quantifying terrestrial palaeoclimate variability from ice-marginal moraines

Glaciated landscapes contain moraines that record past glacier extent from which we can (in some cases) infer palaeoclimate. However, to do so, we need to bear in mind that glacier response to climate change is non-linear and that the sedimentary record created by glaciers is incomplete. We are using forward numerical modelling of moraine building and terrestrial cosmogenic nuclide exposure age-dating of moraine formation to search for palaeoclimate signals in glacial landscapes in Nepal and New Zealand.
