Alaska is changing by the hour. From the far north, where higher seas are swamping native villages, to the tundra around Fairbanks, where melting permafrost is forcing some roads and structures to buckle in what looks like a cartoon version of a hangover, to the rivers of ice receding from inlets, warmer temperatures are remaking the Last Frontier State.
That transformation was particularly apparent at the visitor center here, where rangers were putting the finishing touches on a display that sought to explain the changing landscape of the country's northernmost state. The sign said, "Glimpses of an Ice Age past. Laboratory of climate change today," and it explained how the Exit Glacier has been shrinking over the years, and what scientists are learning as the state heats up.
