US President Barack Obama viewed Alaska's monumental Exit Glacier, in a bid to drive home the impact climate change is already having on America, AFP reports.
Obama traveled to southern Alaska's Kenai Fjords National Park, where he stood against the backdrop of the vast, but receding glacier, where posts mark the ice's retreat since 1815.
"This is as good of a signpost of what we're dealing with when it comes to climate change as just about anything," Obama said.
