Do We Need Special Clothing For Extreme Weather Events?

Comedian Billy Connolly once said "There's no such thing as bad weather. Just the wrong clothing". There's an element of truth in his quip but a simple change of clothing won't enable us to deal with extreme weather events. The thing about extreme weather events is that they are extreme. Such events are rarely unpresidented, if one goes back far enough in time. Manmade global heating has, however, made extreme weather events much more frequent. Some climate scientists now feel that no location is safe from the recent kind of extreme heat events plaguing Western USA and Canada (https://www.theguardian.com/environment/2021/jul/01/nowhere-is-safe-say-scientists-as-extreme-heat-causes-chaos-in-us-and-canada). There has been intense focus on the little town of Lytton in British Columbia, where temperatures reached almost 50 degrees Centigrade. The devastating effects of prolonged extreme heat in Seattle and Portland have also been newsworthy. Extreme weather events are not, of course limited to extreme heat. The events can be droughts, extreme rainfall, flooding, mudslides, hailstones, hurricanes etc etc. The worried climate scientists appear to be recognising, however, that climate change is happening more quickly than they predicted. It's hard to think of the extreme temperatures in the Western US and Canada as having any benefits. They do, however, forcefully bring home the message, that there is a collective need to do something urgently about 'greenhouse gas' emissions. Environmental problems in more remote areas of the globe seldom have such traction. A word of warning. We took centuries to get into the present mess. Even if urgent action is taken now, it will be decades (at best), before weather patterns become more predictable. Extreme weather events will still occur but they will, hopefully, become less frequent.
