I'm old too and I truly believe that we will continue to be here 10-20 years from now with roughly the same world we've always had.
New England has lost over 600 ski areas. There are fewer and fewer places with good enough conditions to grow coffee (a shame as I feel like the culture around fine coffee is just now coming into existence in the US). Enjoy oysters, clams, and scallops while you can as ocean acidification is killing them in droves. As soil heats due to global warming, it releases carbon dioxide, accelerating these effects.
I don't think the world is the same for anyone working in these industries or in tourism. Folks on HN are also generally isolated from the effects of the kinds of droughts that caused the Arab Spring, or from having to home refugees of climate change whose islands are disappearing to the rising sea levels.
It has been argued that Yemen is the first resource exhaustion war - the country has extremely limited water supplies.
The West is going to have to look at the possibility of a lot of refugees in the future, with the option of taking them in or watching them die.
Being near the cost isn’t necessarily worse than being inland as the sea can help regulate the extreme temperatures. I live in a costal city which basically sits around 100meters above sea level, on a good foundation, so the higher amount of rainfall and increasing sea levels aren’t really a worry. I work in another city 40km in land. In the winter my work place can be absolutely frozen while my hometown sits around 0 degrees, and vice versa in the summer. We had a really bad heatwave this summer, but it was 5 degrees worse at my work place than my home.
But basically you’re only going to be fine if you live as far north as Canada or northern Germany.
You’re spot on about climate refugees though. Syria was/is a war about water control, and now Yemen is in the same boat.
The real worry isn’t that though. It’s all the methane gas locked in the permafrost. It might make the air unbreatheable to humans, and then the rest really won’t matter.
That doesn't mean you get to mess it up for the rest of us.
