I am currently in Western New York, not far from Buffalo. Weather-wise, this area is most famous for its deep winter snows. But it's also famous for mild summers. When I was growing up here in the 1950s and 1960s, summer temperatures in July and August were in the 70s most of the time, and anything above 85 degrees was considered "scorching." When air conditioning became common, Western New Yorkers usually thought the expense was not worth the few days they'd need it.
Now, for about a week, temperatures have been in the 90s, with a heat index yesterday that stretched into triple digits. When I asked folks who live around here, they said that summer temperatures had been rising for the last several years, and they are feeling it. And the local farmers are suffering from a drought.
