This is a really interesting article. I like all your examples of acid rain and heat waves. I have another more unusual example. In November 2016, in Melbourne Australia there was one of the worst Asthma thunderstorms in history. It is believed the weather conditions just before a storm triggered an extremely high concentration of micro pollen particles, that caused widespread respiratory illness. Sadly this contributed to upto 10 deaths in a single day. Its surprising how vulnerable we actually are and are at the mercy of the weather.
