End-of-Summer Recorded Arctic Sea Ice Extent to be Low




NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder reported that Artic sea ice have reached its yearly lowest extent on 13th September, 2017. The consistent long-term record which began in 1978 showed that Artic sea ice minimum extent appeared to be year’s eighth lowest. NSIDC and NASA analyzed satellite data and recorded ice to be at 1.79 million square miles (4.64 million square kilometers).

Arctic Sea Ice is also referred to as the planet Earth’s air conditioner. The white surface of these ice sheets bounces solar energy back to space and thus cools the globe. Since the late 1970s, the minimum summer time extent has been decreased due to global warming. The temperature was moderate this year for such high altitudes. The minimum sea ice extent for 2017 is 610,000 square miles (1.58 million square kilometers). It was below the 1981-2010 average minimum extent.
