The bourgeoisie will never do anything about climate change. They haven't got the money; they can't agree on anything; they're too busy fighting wars with each other; and all-in-all they've had it. It's just a question now of whether we, the working class, are up to making our revolution before it's too late, and the next ice-age, or submersion by the oceans, or mass starvation and epidemics, or whatever it'll be, puts us all out of our misery.

The bourgeoisie doesn't even talk about climate change anymore: they know they can't do anything about it. All they're interested in now is: gun control for civilians or not; can we get away with using chemical and biological weapons; can we get away with imposing sufficient austerity on the working class to keep capitalism going till the next "recovery"; how do we go on appearing to look like "world leaders" when we don't know what the fuck we're doing, and most people are sick of us; how can we go on maintaining that our bourgeois democracies really do believe in peace, freedom and equality for all, when anyone with eyes to see can tell its all a set of hypocritical lies; and how do we insist on our rule, our dictatorship, when the majority of humanity no longer get any benefit from it, only increasing misery?

So, calling on "world leaders" (lol) to do something about climate change, has about as much chance of achieving anything, as calling on world leaders to solve the very crisis of capitalism which caused it in the first place. We have to get rid of the bourgeoisie!
