New satellite data has revealed the Arctic is melting at a “frightening rate” due to the excess heat caused by human greenhouse gas emissions.
End-of-season Arctic multiyear sea ice – the ice that persists over several years – was roughly 50 centimeters (1.6 feet) thinner in 2021 than it was in 2019, the figures show, a drop of around 16 percent in just three years. It’s being replaced by less permanent seasonal sea ice that melts completely every summer.
Over the past 18 years, Arctic Ocean winter sea ice has lost one-third of its volume – a staggering figure that may have been underestimated in the past, says the research.It’s the first study to use years of satellite data to estimate both ice thickness and the depth of snow on top.
“Arctic snow depth, sea ice thickness and volume are…
