The first summer on record in which practically all of the sea ice in the Arctic melts could occur much earlier than previously expected. In a new study, scientists warn that the ever-increasing greenhouse emissions may bring us closer to an ice-free Arctic by the end of the decade.

Report authors say daily sea-ice free conditions could be avoided if global temperature change doesn't exceed the 1.5 C threshold. But already, northerners are feeling the effects of the warming climate.

The first ice-free day in the Arctic Ocean could arrive as soon as this decade, warns a new study. Climatologists from Colorado University (CU) Boulder and the University of Gothenburg have used computer models to investigate when the Arctic might experience its first ice-free day.

Asthe Arctic warms at an unprecedented rate, scientists are bracing for an environmental milestone: the first ice-free day in the Arctic Ocean. New research shows that this event could occur as early as 2027 — a sobering prediction that highlights the rapidly escalating effects of climate change.
