Recuo dos glaciares
"Melting glaciers start countdown to climate chaos"
"For centuries, writers, painters and photographers have been drawn to the wild and seemingly indestructible beauty of glaciers. More practically, they are a vital part of the planet's system for collecting, storing and delivering the fresh water that billions of people depend on for washing, drinking, agriculture and power. Now these once indomitable monuments are disappearing. And as they retreat, glacial lakes will burst, debris and ice will fall in avalanches, rivers will flood and then dry up, and sea levels will rise even further, say the climate experts. Communities will be deprived of essential water, crops will be ruined and power stations which rely on river flows paralysed.
As a result, people will have to change their lifestyles, their farming, even move their homes, says Achim Steiner, executive director of the United Nations Environment Programme (UNEP). He also fears the problem could exacerbate tensions over inadequate supplies between neighbouring states and countries, possibly spilling over into conflict."
