It's too late to wish for that. We've already emitted too much, and didn't slow enough in time to avert catastrophic climate change. We will likely live through it, but we'll suffer. And those in poorer, hotter countries will die en masse. Wars will likely happen as refugees flee countries now made inhospitable. Fascism will rise as richer countries, more able to weather the storms, become insular and focus on domestic issues to the detriment of the aforementioned refugees. Perhaps revolutions will happen. Extreme heatwaves, hurricanes, tsunamis, will threaten coastal and tropical cities, and island nations in particular, but even cooler countries will be stricken with fatal heatwaves, just less often.

None of this is "if" we miss some target. We already missed it. It is already set in stone. We can only do our best to ensure it doesn't get even worse than that. That's still not the worst possible outcome.
