Global glacier melt is accelerating, scientists say

Ice loss from the world's glaciers has accelerated over the past decade , scientists say.

Around 36% more ice lost in the 2012-23 period than in the years from 2000-11 .

On average some 273 billion tons of ice are being lost per year -- equivalent to the world population's water consumption for 30 years .

The findings are "shocking" if not altogether surprising as global temperatures rise with humanity's greenhouse gas emissions.
