Climate change is probably happening, sure. But you’re deluding yourself if you think that we’re going to come up with a way to solve it systemically, or that anyone in power actually cares about the issue at all. The more likely outcome is that more scammy regulations are passed that don’t actually help anything except enrich government contractors and politicians while more and more negative externalities are pushed under the rug. Meanwhile the system is helped inch forward towards disaster by well-intentioned people who feel that they need to “do something.”

We cannot afford to do something, we need to focus on the most effective measures because political capital for that topic is not endless. You should also try not to increase other significant problems.

Millions of houses suddenly going underwater in the space of a few decades is going to cause a hell of a lot more issues in the housing market than adding solar panels.

Which houses, where? Because iirc sea levels aren't expected to go up by more than 1m this century, and also IIRC that's not enough to make New Orleans or Orlando infeasible.

Your house, if you own one that is, also needs to have a roof with the right angle and alignment for solar collectors to be feasible. It is hard to find a general rule for building houses.

Solar collectors make sense, even the economic aspects. If people actually have the money to spend on them, they probably will do so anyway.

Despite all the wailing and hand-wringing, there is actually no credible evidence that sea levels are rising. (This ranges from tidal measurements to photographic comparisons of the same site over nearly two centuries!)

Alarmist "climate models" based on wishcraft and paranoia can never be allowed to carry more weight than actual reality. (Well, assuming you beleive in actual science.)

you mean something like prevention of overpriced/highly-speculated housing prices?
