You do realize the effects of climate change will not be something for which you can just isolate your bedroom for, then move on.
Everyone needs water. Directly, and for food production. The most populous regions in the world run on meltwater. The Indus Valley. Pakistan. Bangladesh. Indonesia. California. Central China. There are thousands such locations as well, by the way, just smaller. Meltwater that only comes if not only the planet is hot, but is hotter this year than last. If not, ZERO meltwater comes. Not a little bit. Zero. If you stop global warming 2 billion people need to be relocated.
To make matters worse, one of the "points of no return" which is coming global warming will switch from pumping water INTO the atmosphere to pumping water OUT of the atmosphere. This will turn the "inside" (any location sufficiently far from a coast) of countries like India, Africa and China back into the deserts they were 500 years ago. Except, it will do so rapidly. We don't know, of course, but certainly less than 100 years. Potentially much less.
If you calculate energy required, you will conclude that lifting water is a nonstarter. With current energy generation we cannot bring water to these locations. Never mind that most don't even have railway connections, never mind electrical power to the trains. We cannot realistically use desalinated water at elevations above maybe 300 meters. It's just not happening.
To make matters worse, both things are tipping-points. There is very, very little change while you get closer to the tipping point, then all the builtup change happens VERY suddenly. And this will happen twice, a two-punch situation, maybe a decade or two apart. First meltwater will stop, entirely, in one or two years, and it will not come back for tens of thousands of years and then a decade or so later rains will stop.
Walkable cities and isolated buildings do exactly nothing to stop any of this.
Indonesia is surprisingly big and most of the land is surprisingly far away from the coast. A lot of it will dry out, and effectively cut water supply to Jakarta.
