Glaciers are important indicators of climate change. Global warming causes mountain glaciers to melt, which, apart from the shrinking of the Greenlandic and Antarctic ice sheets, is regarded as one of the main causes of the present global sea-level rise. Tibet’s glaciers are also losing mass clearly, as scientists reveal using satellite-based laser measurements. Over the last decade, the research team has detected a “clear loss in mass of around 16 gigatons a year in around 80 percent of the Tibetan glaciers,” says a glaciologist....
