Unfortunately AC is going to become a necessary reality even in countries where it is traditionally avoided, like the UK or mainland Europe. Here in Germany we had to buy one for our rabbits, who will simply die without it. In the UK it will reach 40 next week across many areas of the country. An article on the Guardian says that we can avoid AC in these extreme weather situations by using techniques such as "opening windows". Totally delusional. Then you have the UK climate deniers which are extremely numerous and are claiming that 40C is a totally normal and expected part of the British summer.
I think that it will not be long before believing in anthropogenic climate change will become political suicide, since who wants to hear the bad news that we have no solution for? Even worse are those who claim that "we will solve it with science, we always do". It is already too late, and the momentum is getting insane. Nothing we can do about it. A billion brown people will die, and all white people will have AC.
