Ha, I sat through the exact same experience in Vancouver a few years ago in mid-June, it was about 50 F outside instead of the normal 70. Never invite a climate change hustler to your graduation ceremonies (it wasn’t Obama up here, some lesser doofus).
Yes, the Gore effect has been noted in quite a few northern cities. Gore shows up to speak and cold weather shows up to humiliate him. (Wikipedia references)
Reported global warming related events attended by Gore combined with striking temperature minima respectively unexpected snowfall include visits in Australia, Italy and Peru. An opinion column in the Ottawa Citizen then stated “Mr. Gore arrived in the late antipodean spring, together with a remarkable cold front and a late-season boon for the ski resorts.” A Gore lecture at Harvard University on an October day 2008 with exemptionary low temperatures is frequently mentioned. When Gore testified about global warming before the Senate committee in January 2009 the local schools had a snow day. The Gore effect is mentioned as well at events without attendance of Gore, so when Nancy Pelosi had to cancel an appearance at a global warming rally in March 2009 due to a snowstorm and when the 2009 United Nations Climate Change Conference coincided with a severe snow storm in Denmark. During Gore’s July visit to Australia in 2014, meteorologist Joe Bastardi noted that his presence coincided with Brisbane recording its coldest temperature in over one hundred years.
