Abstract
First results of the project assessing how climate change will affect mass-movement hazards in the high Andes of central Chile, comparing two climate models for the period 2030–2050.
One model (HadGEM2-ES) projects more rainfall events above 20 mm/day; the other (MPI-ESM-LR) fewer but more extreme events, of up to 150 mm/day. The key effects identified are the enlargement of catchment areas, the shift of the rainy season towards less cold months and possible intense spring rainfall.
