We already have all the tools needed to stop climate change. The current problem is that nobody wants to pay for it.

Nobody wants to sacrifice their own economic growth / position.

But also, would it actually make a difference at this point? That is, can it be stopped, or have we passed the point of no return? I believe the latter.

More and faster warming is always worse than less and slower warming, so every reduction in CO2 helps.
