7. The biggest issue is that the sea levels will rise.

And because most people live by the sea, that will cause significant relocation of people, which will cause territorial disputes. This is a long term trend, however. It could be 50 years before it's realized that people are relocating en mass to get away from the ever encroaching seas. This will cause not only a demographic and economic issue but will be seen as probably the largest migrations of humans that we've ever seen. And it will come quietly, just people getting flooded from time to time and saying "screw this," and moving on.

And to be clear, sea levels will rise if we cut off the CO2 tomorrow. There's a lot of built up heat in the oceans. It's where all the heat has been "hiding" so long.

Outside of that, there will be more extreme storms (we're seeing it now with the current big freeze), on a more regular basis, which will affect economies. More drought that is longer and more devastating (this will in particular impact the India/Asian countries which have the highest populations).

Not that you would necessarily live to see the worst effects, but it's a daunting problem and every year we're not looking for answers, it's going to come.
