When it counted? Each degree the climate changes is worse than the last. The first .5 degree of climate warming was probably actually a good thing but going from 1.0 to 1.5 isn't and 2.0 to 2.5 is much worse than that. We don't know if low lying Pacific islands are doomed and if we'll have to be accepting a bunch of refugees but it's possible we can save them. What we almost certainly still have the power to prevent is tens of millions of people in India from dying in heatwaves where the dew point exceeds survivable temperatures without air conditioning. We don't actually know where runaway positive feedback loops might be.
