My ONLY question as to weather killing people is, HOW do they calculate it? For instance, here in new england, if someone is out driving in inclement weather, loses control, and dies as a result, is that attributed to a car crash, or weather? If weather, I would break it down a little further; did that person NEED to be out (ie; going to the hospital)? Likely not.
One other thing; most people who live in those environments have learned to cope with them. Again, here in NE, we have access to good cold weather clothing, shovels, snow blowers, etc. So, the equipment is there, it comes down to someone using it.
I think the LEAST safest place to live is among people who simply are oblivious to their environment! The safest? Probably a hue commune where we can all gather together
