CO2 Budget Depletion

Old sea ice has almost vanished

DATA SOURCE
Arctic sea ice is getting younger, thinner and less stable. While Arctic sea ice comes and goes with winter freezing and summer thaw, a significant portion of Arctic sea ice once remained through the Arctic summers, surviving from year to year. Ice older than 4 years old used to make up over 30% of the Arctic Ocean, but it now makes up only 3.1 percent of the ice cover. Further, thin first-year ice now makes up the majority of the Arctic Basin, making it more vulnerable to melting out each summer.
