More extreme weather doesn't mean you can't go outside and play. It means mega-droughts. It means crop failures. It means extreme flooding. It means paying more for everything as more people fight over fewer resources. Wealthy countries will be able to somewhat deal with drought in parts of their territory, but poorer countries will experience more famine and hunger. More people will die from heat-related illness.
>But add up all the deaths and inconveniences from this, assume it gets worse, and the world is still incredibly better off than it was in the 1980s.
In the 1980s, an American with a high school education could expect to make a good living and maybe have a stay at home parent.
Most modern Americans wont be able to buy a house much more raise a family on a single income. Everything is getting rapidly expensive while wages stagnate or decline through inflation.
