Most anyone living in 2021 is dealing with extremes of weather that they hadn't encountered before. I grew up in what used to be the relatively temperate climate of southern New England, as it is known, the northeastern United States. There were a lot of things I never needed to know about dealing with extremes of weather, because we didn't have any when I was a kid. Since then, I've spent much of my time traveling.
Although I very intentionally tried to organize tours in such a way that I would be traveling to places during a nice time of year -- like touring Australia in Australian winter, thus entirely missing the increasingly scorching summers wherever I might be otherwise, and doing gigs in California and Florida in the winter -- things didn't often work out that way. I have ended up spending lots of time during record-breakingly hot summers in hot places like Texas, Arizona, and Japan, and I have done multiple tours of eastern Canada and Alaska in winter.
The good news is, although climate chaos is terrible and is causing so many problems for so many people and other creatures, the planet has long had a lot of different kinds of weather. We're just not used to having all kinds of weather in all places, like is increasingly happening, to characterize the phenomenon in lay terms, the only ones I know. But there are parts of the world where people are used to all these kinds of weather. I've spent time in some of them, and learned a couple tricks.
