Published: 20 April 2020
A study predicts the Arctic Ocean may be ice-free in summer before 2050, even with emissions cuts. Led by Dirk Notz and AWI, it used 40 climate models, showing emissions will affect the frequency and duration of ice-free summers.
Keywords: CO₂ emissions, global warming, polar bears, IPCC, Fram Strait, Sebastian Menze, Arctic ecosystem.
