Given for many this has been a modern ‘Year Without a Summer’, I don’t think many people will be sympathetic to their loony cause.
I live in central Ohio. It hasn't been over 90 degrees but three times this year - in total. It was 54 last night. My neighbors (who are lifelong Ohioans in their 70s) tell me that they can't remember a summer this cool, ever - and this is coming off a very cold and snowy winter. If you mention the words "global warming", it's met with a belly laugh.
