4 Μαΐ 2021 · Authors of the study warn that melting glaciers are a significant contributor to rising sea levels. Glacier melt across the world has accelerated over the past two decades, a new study finds, with the resulting meltwater accounting for 21% of global sea level rise over the same period.
8 Απρ 2019 · The largest collection so far of glaciological and geodetic observations suggests that glaciers contributed about 27 millimetres to sea-level rise from 1961 to 2016, at rates of ice loss...
28 Απρ 2021 · The world's glaciers are melting at an accelerating rate, according to a comprehensive new study. A French-led team assessed the behaviour of nearly all documented ice streams on the planet....
5 Ιαν 2023 · Glaciers, here referring to all glacial land ice excluding the Greenland and Antarctic ice sheets, are responsible for 21 ± 3% of sea level rise from 2000 to 2019, contributing 0.74 ± 0.04 mm sea level equivalent (SLE) yr −1 .
28 Απρ 2021 · We show that during 2000–2019, glaciers lost a mass of 267 ± 16 gigatonnes per year, equivalent to 21 ± 3 per cent of the observed sea-level rise6.
Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
If all glaciers and ice sheets melted, global sea level would rise by more than 195 feet (60 meters). NASA continuously measures the weight of glaciers and ice sheets – with the twin GRACE satellites from 2002 to 2017, and with the GRACE-Follow On satellites since 2018.
