I’ve been wanting to see this one for a long time, and I’m glad it’s finally come up in my queue. In the end, it’s a straightforward piece that presents its science and facts upfront, without any obfuscation. Plain speech, for once. Sure, there are the emotional cues and it is skewed toward its premise – humanity is causing an unprecedented rise in CO2 in the atmosphere, and the link between CO2 level and global temperature.

I’m going to do what I can. Four stars.
