Table 1 Summary of the climate forcing scenarios. Each forcing scenario was constructed by combining one of the two proxy-based air temperature records (PA and MA1)28,29 with one of the two proxy-based precipitation records (MA1 and TML1)29,30. Initial glacier volume (Vice) is presented relative to the combined modern volumes of the HPS19, Penguin, and Europa glaciers (308 km3; 100%) as simulated in our default model initialization step (Methods “model initialization”).
From: Precipitation drives western Patagonian glacier variability and may curb future ice mass loss
