Watching the final debates of COP20, I'm reminded of that scene in every disaster movie where the hero warns those in power that if they don't step outside of the usual protocol and take urgent action the catastrophic (e.g. meteor, monster, aliens) will take place. The good news is, we too are reaching tipping points.
Every one of us in the Western world has contributed to climate change. We drive, fly, cool, heat. Perhaps we draw pensions from funds that back Exxon and Shell. On and on it goes, since fossil fuel is knit into the fabric of our society. If, as the Times puts it, Tom Steyer is "shadowed by coal," so are the rest of us.
