Heat-related deaths and disruptions to daily life are forcing politicians to reckon, in different ways, with a rapidly warming planet.
Unfortunately, adaptation on its on isn’t doable. It takes ending the use of fossil fuels, which are the main cause of the warming, to make adaptation affordable.
Seasonal heat storage exists.
Basically a big water tank with very thick insulation which can store heat for six months. This is economical for multi-family units, becauses the relative amount of necessary insulation decreases with size (for a cube with 27 cubic meters volume, you need 54 square meters of insulation, for a cube with a volume of 125 cubic meters, 150 square meters).
What can store a hot medium can obviously also store a cold medium.
It is also much cheaper to store heat, than to store electricity.
Here is a description (in German) of applying the concept to a single-family home.
