These two false-color thermal images taken by NASA satellites depict the
rapid retreat of the Columbia Glacier in Alaska over the past 25 years.
The top image shows the glacier’s terminus just north of Heather Island
in 1986. By 2011, the terminus had retreated 12 miles up the inlet, and
is identifiable in the bottom image, just below the “Main Branch”
label, where the striped glacier surface meets the inlet. The blue in
the water below the 2011 terminus is floating ice that has calved off
the leading edge of the Columbia Glacier. (NASA Earth Observatory)
Water Spouts will speak volubly and endlessly about all the issues concerning water. The ongoing degradation, and growing scarcity, of the water supply here in the US, and the rest of the world. The continued absence of potable water in so many parts of the world. The work being done by NGOs, and charities, in the third world, to help alleviate the situation. The emphasis on WASH ( Water, Sanitation, and Hygiene ) so health and healthy water are maintained. "Water Spouts" will spout it all out.
