Article Synopsis – A new study shows that the arctic is losing much of its older sea ice- which is typically thicker, lets less light through to the ocean, and is more resistant to melting- which is putting Arctic ecosystems in danger. “Since 1984, the percentage of multiyear ice cover has declined from 61 percent to just 34 percent, and the oldest sea ice—ice that’s been frozen for at least five years—now accounts for just 2 percent of the ice cover”. Every additional loss of multiyear sea ice “reduces the likelihood of any kind of recovery of sea ice extent in the future”. To read the actual article click here.
