File:Global Surface Map July.jpg
From Global Warming Art
True color composite satellite map of the Earth's surface in July 2004 from NASA's Blue Marble: Next Generation Project. Each pixel appears as it would from directly overhead in the absense of cloud cover. This image and the comparison to January (shown at right) illustrates the significance of seasonal snowfall in affecting the Earth's albedo. Snow covered regions effectively cool the Earth by reflecting sunlight back into space, and hence changes in the range of snow cover can serve to amplify climate changes.
