Arctic sea ice extent has reached its lowest level ever recorded for April, covering just 4.8 million square miles compared to the 1981-2010 average of 5.6 million, according to NSIDC data released today.

Alarming Trend

This marks the fifth consecutive year of record-low April ice extent. Scientists warn that ice-free Arctic summers could arrive as early as 2030, a decade ahead of previous projections.

Global Impact

Reduced Arctic ice amplifies global warming through the albedo feedback loop and disrupts jet stream patterns that drive weather across North America and Europe.
