Question: Take a moment to observe both images below. The Arctic Sea ice has decreased in square miles since 1975. How has that impacted the amount of the Sun's energy being absorbed by the Earth? Image 1: Albedo of surfaces: The percent absorption and reflection of the Sun's electromagnetic energy by different surfaces on Earth. |AMAP Amen e Sun Reflected by atmosphere and clouds 239 23% Absorbed 54% Reflected by ice/snow Reflected by water 85% 15% Absorbed 7% 93% Absorbed Image 2: Data showing changes in Arctic Sea ice from 1975 - 2015. Arctic Sea Ice Loss Average Extent in September 3.5 1998 3.0 1980 2.5 2.0 2012 1.5 10 1975 1995 2005 2015 Year Average Volume 3000 2500 2000 1500 1000 2003-2008 2010-2011 2011-2012 Years O Less exposed ocean water and more ice results in lower energy reflection rates O More exposed ocean water and less ice results in lower absorption of the Sun's energy O More exposed ocean water and less ice results in higher absorption of the Sun's energy Cubic Miles
