A combination of stronger storms, more frequent coastal flooding, larger wildfires, and more severe heat waves.
Of course these sorts of things have always killed people and right now the statistical increases are small enough that it's not unreasonable to believe that they're just fluctuations within normal historical bounds. It would take significantly larger increases in severity and intensity for many people to accept climate change as a contributing factor.
So it's not just that we have to wait for people in wealthy countries to die, it's that we have to have to wait for them to die in high enough numbers that the average citizen acknowledges that there is a problem.
