At the height of the most recent winter season, Arctic sea ice was at its lowest level ever recorded, with climate change playing a key role in this historic decline, the National Snow and Ice Data Center revealed Thursday.

Arctic sea ice reached its maximum levels on February 25th at 5.61 million square miles. This “was the lowest in the satellite record, with below-average ice conditions everywhere except in the Labrador Sea and Davis Strait,” the scientists note.

While there is still a chance that ice levels could bounce back late in the season, the researchers say that outcome is unlikely.
