The climate drivers of glacier wastage at Kerguelen have been explored using field observations, remote sensing data and modelling. After a period of stability between 1950 and 1960, glaciers experienced a massive reduction mainly explained by a drought due to man-made atmospheric warming and the ozone hole Favier et al., Scientific Reports, 2016 |
