Instagram: Arctic Sea Ice Minimum 2014
Sea ice acts as an air conditioner for the planet, reflecting energy from the Sun. On September 17, the Arctic sea ice reached its minimum extent for 2014. At 1.94 million square miles (5.02 million square kilometers), it’s the sixth lowest extent of the satellite record. With warmer temperatures and thinner, less resilient ice, the Arctic sea ice is on a downward trend.
