Don’t expect climate change to get fixed by the governments of the world. Don’t expect that, however noble in intention, the efforts of Gore, McKibben, Stern, and their many cohorts will succeed either. Not on any large scale. It won’t be clean tech or green products saving the day either.
Climate change, like energy scarcity, water pollution, and other serious global issues is merely one symptom of a larger global problem. Tackle the symptoms individually, and at best you might get lackluster results. Tackle the source of the problem, and everything attached to it will be positively affected.
