In that case the answer is staring us in the face: we need to accelerate climate change in order to warm up the cold regions of the world and reduce our reliance on artificial heating.
And this is something that can be fixed with current technology. Today you can easily build housing that uses no fossil fuels for heating, and in actual fact will generate more energy than it consumes (over the course of a year), even in cold climates such as Scandinavia.
But most people disregard this on the basis of cost (in reality it costs a little more upfront but saves money in the long term) or outdated conditionings that buildings need to breath naturally and should not be airtight.
I lived 6 miles from an operating nuclear power plant for decades. It was fine. Interestingly, the most pro-nuclear people are often those who live in the emergency planning zone. It's thought that this is due to the local outreach that the plants do with boy scouts and whatnot.
That's also certainly part of it. I think it's a good thing that people who work there generally feel very safe. Interestingly, the nuclear industry has one of the best occupational health records. Mostly because you have to take a damned training before you operate a ladder.
