John D Boswell at Symphony of Science created a beautiful video that describes our greatest challenge to date – climate change. Yes, the subject is a downer, and I would love to believe that it really isn’t happening as much as the oil industry would like us to. But the reality is that it is happening, and it’s getting worse.

Boswell’s video features the late Isaac Asimov, speaking out on climate change way back in the 1980’s. It’s a reminder of the fact that human-caused climate change is nothing new; we’re only now starting to feel the worst effects of it.

There is, however, some hopeful news. The climate change we are experiencing is caused by us, and that means we can do something to reverse it. Boswell emphasizes this point in his video, and turns what could have been a depressing commentary on rapidly diminishing polar ice into a message of hope; we can correct this problem.

If we choose to.
