Thank you. I think we really do need a return to some form of optimism. Growing up I was told endlessly that by now we'd be out of fossil fuels and things would be terrible for a variety of other reasons. Some of that has come to pass, some not, some has reversed (ozone).

Sometimes the positive effects of sustained efforts have had a real impact over time. Having a cynical and defeatist attitude works against that. I don't know the roots of those attitudes exactly, but from the people I know they're not related to climate change, the country's leader, cultural issues, etc. It's more like those are a good reason for them to be more vocal about their underlying cynicism which has different roots (family life, general temperament, etc).

We have real problems. Very big ones. A defeatist attitude will ensure we end up in the worst of all outcomes. I wonder if we just have too much change too fast for our society to keep up and figure out ways to function better with the new constraints.

Edit: clarification
