We went to Glacier National Park and backpacked there and Glacier National Park’s glaciers, which have been there for at least 7,000 years, are forecast to be completely melted away by 2020. We tend to view the impacts of climate change as far off things that will happen to future generations but the changes are underway now. My kids in 2020 will still be teen-agers. That was part of the reason I wanted to get them on these trips because I think these places will be really different.
