This should be a non-issue, or even an opportunity, but it's a complete crisis for capitalism. As a society we need rapidly decrease the carbon emissions from our buildings. This means electrification of utilities, but more importantly it means reducing the heating/cooling load of buildings. This would require a massive building campaign of new homes, depressing the price of existing homes across the board. Then once population demographics have shifted enough to begin depressing the price of homes on their own, begin systematically destroying the older housing stock.
