The three people who lost their lives in Alaska are just a few of those who have died on trips to see the world’s fast-disappearing glaciers. But there’s also another motivation increasingly present — the desire to see the glaciers before they disappear. In Alaska, Sheldon used to be able to find a good area for ice climbing for the whole summer. Many are convinced danger is manageable, he told CNN, but “if you’re honest about it, that might often be a rather naive understanding.”As well the safety issues glaciers pose tourists, tourists are also a huge risk to the glaciers themselves. As the glaciers shift, so too will glacier tourism, something that’s starkly clear to Sheldon.
