And let’s be clear: moral clarity is not the same thing as naïveté. It is naïve to expect that governments and corporations will do the right thing, or that someone else will handle it. It is naïve to think we can “solve” or “stop” climate change. It is also naïve to give up, when every tenth of a degree of warming we prevent, every centimeter of sea level rise we avoid, every species we save, and every increasingly unnatural disaster we avert all matter so very much.
