Going green is much cheaper now than it was. That may invert at some point but it's hard to predict when that might be.

Thats certainly true, but to prevent the worst of the effects of climate change we also need to do much more now than before (its debatable at this point whether its even reversible, that wasn't always the case). I suppose the point is that what was enough a decade ago costed more then than it does now, but thats no longer enough
