How global warming can shrink glaciers and alter frontiers
ONCE frontiers were changed by armies. Now the job is done by global warming. Italy and Switzerland are preparing to make—or rather to recognise—alterations to the border that runs through the Monte Rosa massif of the Alps. Despite what romantically minded locals may say, the name of the massif has nothing to with the pink blush its peaks acquire at sunset. It comes from a dialect word meaning glacier. The massif has nine glaciers. In several places the line between the two countries is set at the watershed. Because of global warming, the glaciers have shrunk, so the watershed has shifted, “in some places by as much as ten metres”, says General Carlo Colella of Italy’s Military Geographic Institute in Florence. In January, after four years of work by the general and his staff, Silvio Berlusconi’s cabinet approved a change in the frontier.
