Virtually All the planet’s glaciers are losing mass in an ever increasing rate, leading to over a fifth of global sea level rise this century, based on unprecedented study published WednesdayGlaciers — enormous bodies of water that is frozen which sit above earth — have been melting quickly because the middle of the 20th century, but until today the complete extent of ice reduction had only been partly understood.

An global group of investigators has for the first time detected all Earth’s several 220,000 glaciers, excluding the Greenland and Antarctic ice sheets, to correctly assess the quantity and speed of melt within the previous two decades.

Analysing pictures taken by NASA’s Terra satellite, they discovered that involving 2000-2019, the planet’s glaciers dropped an average of 267 billion tonnes of ice every year.

However, the team also discovered that the speed of glacier melt had accelerated sharply during precisely the exact same period.

However, involving 2015-2019, they dropped an average of 298 billion tonnes every year.

This glacial melt has led to 21 percentage of sea level rises in the analysis interval, the investigators said — equal to 0.74 millimetres per year.
