For example, I've lived in the midwest USA most of my life. Every July and August is hot and humid, with many days in the 90-degree (F) range. This used to just be normal summer weather and unremarkable. Now, anything over 85 degrees is a "heat advisory" and over 90 people are advised to stay indoors and avoid activity. They also publish absurd "feels like" temperature e.g. "today's high 91, feels like 117." I'm sorry, in no real world does 91 "feel like" 117.
It does, and there's no voodoo needed to understand why. In a super-humid environment your body's way of dealing with the heat - sweat - just isn't as efficient. On a breezy day in the desert, 117 is... well, it's damn hot, but if you're staying hydrated and take steps to keep from getting sunburned, it's kind of surprising how tolerable it is. In that environment sweat works its magic quickly and effectively.
(I live in the midwest and I'd trade fifteen or twenty degrees for the humidity we get this time of year. My first visit to the Nevada desert was kind of an eye-opener)
For example, I live in an area that traditionally receives moderate rain and snow during the winter. This past winter, though, we had very little snow while in the past week a major freeway has flooded twice due to heavy rains.
Of course, this is one year and doesn't, on its own, make a trend, but if this continues we'll need to alter how we behave, and possibly how out infrastructure is designed, in order to adjust.
And unfortunately when the climate is changing rapidly, it's suddenly very expensive to alter your coping strategies to adjust to the new normal.
I'm originally from Chicago so I find it all very amusing. I don't recall the L ever shutting down, nor do I remember any news articles about thunderstorms unless there were tornados inside the city limits.
