DrEvanGowan, Fox et al investigate the interesting problem of the increasing intensity of Antarctic Peninsula glaciation during the past 3 million years or so. They find that the increase in glaciation is purely a function of tectonic uplift of the Peninsula, rather than requiring a climatic explanation. The uplifting mountains made it easier for an ice sheet to develop over time. #ClimateChange #Antarctica #IceSheets https://www.nature.com/articles/s41561-023-01336-7
