Antarctica is losing more ice at an accelerating rate. Over the past 10 years, the rate of ice melt has tripled, from 73 billion tonnes per year, to 219 billion tonnes. As a result, sea levels are rising faster as well, as shown by a combination of measurements conducted by 24 international research groups. The results of this study will be published on Thursday, 14 June in the scientific periodical Nature. One of the five research leaders is Prof. Michiel van den Broeke from Utrecht University.
For the publication in Nature, the researchers combined data about Antarctica that have been collected by 24 different research groups over the past 25 years. They then determined the changes in the thickness and mass of the ice sheet that covers Antarctica. Their results show that the ice loss has tripled over the past 10 years, to an average of 219 billion tonnes per year for the period 2012-2017.
