Climate change is accelerating the melting of the world’s mountain glaciers, according to a massive new study that found them shrinking more than twice as fast as in the early 2000s. The world’s glaciers lost ice at the rate of about 255 billion tons (231 billion metric tons) annual from 2000 to 2011, but that quickened to about 346 billion tons (314 billion metric tons) annually over about the next decade, according to the study by journal Nature. And the last few years, the melt has accelerated even more, hitting a record 604 billion tons (548 billion metric tons) lost in 2023, the last year analyzed. The study drew on an international effort that included 233 estimates of changes in glacier weight. In all, the world’s glaciers have lost more than 7 trillion tons of ice (6....

Even if global warming were to stop completely, the volume of ice in the European Alps would fall by 34% by 2050. If the trend observed over the last 20 years continues at the same rate, however, almost half the volume of ice will be lost as has been demonstrated by scientists from the University of Lausanne (UNIL, Switzerland) in a new international study. By 2050, i.e. in 26 years' time, we will have lost at least 34% of the volume of ice in the European Alps, even if global warming were to stop completely and immediately. This is the prediction of a new computer model developed by scientists from the Faculty of Geosciences and Environment at the University of Lausanne (UNIL), in collaboration with the University of Grenoble, ETHZ and the University of Zurich. In this scenario, devel...
