most places in the world think 30 degrees is a nice day and -10 is an emergency. in canada, -10 is a nice day and 30 degrees is an emergency.
the climate has already changed and we need to readjust our metrics so that they are more normal. it's been 30+ degrees here almost every day since mid june, and that's not some kind of emergency, it's just summer. yet, we send out heat warnings at 30 degrees. that's ridiculous. we should be happy we're getting nice weather like the rest of the world does when it's 30 degrees.
heat warnings should not be sent until there's three days in a row above 35 degrees.
this shift in mindset will normalize our perceptions about heat so they are more in line with the rest of the world, and re-establish a heat event as something rare, rather than just normal summer weather, which we should be enjoying, not complaining about.
