More counter-examples. From “The Winter that Never Ends.” From Seattle’s King5 News:
16 May 2017 – A Winter Weather Advisory is in effect for the Washington Cascades until this evening, with accumulating snow as low as Snoqualmie Pass.
“While it’s not unusual to see May snow in the Cascades, it is somewhat rare to see accumulating snow this low this late in the year. The Cascade passes could see 1-4 inches of slushy snowfall. Above 4,500 feet, the totals will be closer to 6-12 inches.
‘More counter-examples’ – meaning the climate is not changing? Even despite the comment of ‘it is somewhat rare to see accumulating snow this low this late in the year.’
No. Meaning global warming cannot be proven by record hot temperatures. If it could, then record cold temperatures and record cold events would be a counterexample.
