World’s glaciers melting fast: 9.6 trillion tonnes of ice lost in last 50 years

The most comprehensive glacier assessment yet reveals that glacier melt was responsible for 27 mm of sea level rise between 1961 and 2016. Ice loss from glaciers is now the second biggest contributor to rising sea levels after warming water. If glaciers continue to melt at current rates, most — including many in central Asia, central Europe, western Canada and the USA — will vanish during the second half of this century.
