My paraphrase: First, recognize that getting effective action on climate doesn’t depend on getting every citizen to be climate-concerned; for example, consider smoking policy action: only 50-60% of citizens were on board. Second, there are going to be climate-insincere politicians. Recognize that a climate-sincere politician is going to put a price on carbon or enact regulations that phase out coal, gas, petrol, and diesel. Climate-insincere politicians do educational and research stuff but say carbon taxes or regulations are too prohibitive. They set distant targets (yes, targets are good) but never do anything; with a target, we need to see policies towards the target. Finally, climate-sincere citizens need to be strategic and work hard against the election of the most climate-insincere politicians, rather than being purist, splitting the vote, and enabling the bad guys to get elected.
