A return doesn't have to be economic. I'd rather lose money and not die than make trillions and drown. (Obviously hyperbolic example, but my point is that the number in my bank account isn't the only thing to invest in)
But you can't actually get that outcome. You'll lose money AND people will drown. That's the point here. You can decide to lose money or not, but you can't dictate the climate. Sorry to be the arsehole here, but everyone seems to be fooling themselves and we need to stop in order to make a real plan.
