'Time to Choose': Climate change documentary has a hopeful tone

'Choose,' which is directed by Charles Ferguson, lays out a series of possible solutions, all of which are already available, to climate change.

What separates Charles Ferguson’s “Time to Choose” from the many other documentaries about climate change is that, after dutifully presenting many of the usual horrifying climate statistics, it lays out a series of possible solutions, already available, to the crisis. (Oddly, hydraulic fracturing is never discussed.)

In interviews, entrepreneurs, scientists, and innovators from around the world proclaim a near-future in which commercially advantageous renewable energy installations would drastically reduce our dependence on fossil fuels. Here’s hoping. Grade: B+ (Unrated.)
