As the planet's polar ice sheets destabilise amid rising temperatures, a landmark UN assessment of Earth's retreating frozen spaces is also set to spell out how melting mountain glaciers will impact humanity in the decades to come.
It says that the Greenland and Antarctic ice sheets lost roughly 400 billion tonnes of mass annually in the decade to 2015, corresponding to a sea-level rise of around 1.2 millimetres each year.
"In the past 100 years, 35 percent of global sea-level rises came from glacier melting," Anders Levermann, climate professor at the Potsdam Institute for Climate Change Impact, told AFP.
