On my birthday, I checked out this NASA Earth Laboratory article. The Okjökull glacier was healthy in 1900, beginning to suffer in the late 40s, and was pronounced dead/gone/kaput in 2014. Five years ago! In three days, on the 18th, there will be a memorial atop where frozen snow used to tower. I, for one, will offer a brief heartfelt farewell. As glaciers vanish, as coral reefs die, as species go extinct, we should add our mental goodbyes. Goodbyes, after all, are goodbyes.
