Over the past two decades, glaciers worldwide have lost 273 billion tonnes of ice to a warming world, driving sea levels to rise at an accelerated pace, according to a decades-long comprehensive analysis.

The melting ice from glaciers worldwide is leading to an increased loss of regional freshwater resources. And it is causing global sea levels to rise at ever-greater rates. Since the year 2000, glaciers have been losing 273 billion tons of ice annually,

Leading scientists are warning that the world's glaciers are melting at an unprecedented rate far faster than had ever previously been anticipated.
