I have to say, deepwater, the few things I have seen which have actually given me a bit of hope are, oddly enough, articles in the right wing press where people see a business opportunity to monetise tackling climate change - the point at which electricity produced by Dogger B fell below the spot price for electricity produced by gas-fired stations, for instance.
The other thing that might do it is when the west realises the massive threat to global security posed by climate change.
The question is whether those things happen fast enough.
But no, people aren't going to act out of altruism. That's the tragedy of the commons all over again.
