Sarah Palin: glaciers, wolves and global warming

A 1917 sign in Kenai Fjords National Park in Alaska shows where the end of the Exit Glacier used to be — a mile from the current edge of a receding wall of ice.

Read my colleague Ed Stoddard’s fascinating tale from the park about the U.S. ‘environmental wars’ since Republican presidential candidate John McCain picked Alaska Gov. Sarah Palin as his running mate.

Would a Vice President Palin sway a President McCain away from his long-standing drive for tougher action on climate change if the Republican pair win November’s election?

Palin favours expanded drilling for oil, opposes a Bush administration decision to list polar bears as threatened and doubts that human activities cause climate change, which is warming the Arctic twice as fast as the rest of the globe. The aptly named Exit glacier, like almost all glaciers around the world, is shrinking.
