With the Arctic sea ice area (SIA) rapidly declining since 2000, a study forecasts the Arctic Ocean to become ice-free near mid-century in September.
The panel said, “It is likely that the Arctic Ocean in September, the month of annual minimum SIA, will become practically ice-free. Hence, uncertainty remains in whether or not the Arctic will become ice-free under the lowest emissions scenarios, as well as in understanding the observed SIA changes throughout the year.”
Additionally, the study showed that anthropogenic aerosol forcing had offset about 23 percent of the GHG-induced Arctic sea ice extent decrease.A significant decline in Arctic SIA would severely impact human societies and natural ecosystems. “An ice-free Arctic is creating new business opportunities, political challenges, and threats to the ecosystems and local communities.”

Observationally-constrained projections of an ice-free Arctic even under a low emission scenario - Nature CommunicationsA dominant influence of anthropogenic greenhouse gas increases on Arctic sea ice area is detectable in all months. By scaling climate models’ sea ice response to best match observed trends, an ice-free Arctic in September is projected under all scenarios.
