I tried to explain this several times. Facing facts means "We're not going to reduce CO2 levels sufficiently, so we'd better start thinking about how to manage what is likely to happen."
Instead of spending trillions on CO2 reductions which would be inadequate, maybe we should consider spending SOME of that one ways to manage a higher MSL and hotter temperatures.
Or, we should get serious about other methods for managing this, like salting the oceans with iron.
