Glaciers, which cover more than 10% of the country's landmass, shrank in 2019 to 10.4 thousand square meters.square kilometers, according to the
Since 1890, the area of land covered by glaciers has decreased by almost 2,200 square meters.sq.km, or by 18%. But nearly a third of this process has occurred since 2000, according to the latest calculations by glaciologists, geologists and geophysicists.Experts have previously warned that Iceland's glaciers are at risk of disappearing completely by 2200.
Ice retreat over the past two decades is almost equivalent to the total surface area of Hofsjokull, Iceland's third largest ice cap: 810 sq. km.
In 2014, glaciologists stripped the Okjökull glacier of its status as a glacier, the first for Iceland, after determining that it was composedout of the dead ice and no longer moves like the others.
According to the study, almost all of the world's 220,000 glaciers are losingmass at an ever-accelerating rate: a fifth of global sea-level rise this century is due to glaciers.
Analyzing images taken by a NASA satellite, the authors found that between 2000 and 2019, the world's glaciers lost an average of 267 billion tons of ice each year. The team also found that the rate of glacier melt accelerated dramatically over the years. same period.
In the period from 2000 to 2004, glaciers lost 227 billion tons of ice per year, and in the period 2015–2019, they decreased by an average of 298 billion tons per year.
