The Gore Effect is an informal and satirical term which alleges a causal relationship between unseasonable cold weather phenomena and global warming activism, with particular emphasis on events attended by former Vice President of the United States and Nobel Peace Prize recipient Al Gore. Usage started when a speech of Al Gore on a global warming rally held in New York City met extremely cold winter weather in January 2004 and according Andrew Bolt after another Gore speech took place on a strikingly cold day in Boston in the same year.
While Steve Benen of the Washington Monthly called focus on the claim "insulting", CNN metereologist Rob Marciano describes use of the effect as a mere running gag among weather forecasters: "It's the Al Gore effect. I mean that - that's - in the weather community, we kind of joke about it. It's just a bad timing. Every time there's some big weather climate conference, there seems to be a cold outbreak. ... But, globally, we are still warming."
The Toronto-based national newspaper Globe and Mail defined the term in 2007 quoting a user's submission to the online Urban Dictionary website as "the phenomenon that leads to unseasonably cold temperatures, driving rain, hail, or snow whenever Al Gore visits an area to discuss global warming." According to an article at the Politico website: "The so-called Gore Effect happens when a global warming-related event, or appearance by the former vice president and climate change crusader, Al Gore, is marked by exceedingly cold weather or unseasonably winter weather."
"Climate skeptics" use the term "half-seriously" in relation to the weather conditions at global warming venues. German authors Daniel Rettig and Jochen Mai described the effect in 2012 in a popular science book about psychological mechanisms and memes.
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.
Harald Martenstein in Die Zeit introduced the term to German audiences, describing the effect as "Gore's private climate disaster". The general use of the expression is, according to Martenstein, only half ironic, since local cooling occurs in the presence of the Warming Prophet, Gore, too often to be discounted, proving that God has a sense of humour. A Competitive Enterprise Institute spokesperson and The Washington Times editorial staff have expressed a similar view.
Lack of distinction between weather and climate
Curtis Brainard of the Columbia Journalism Review has called coverage of the Gore Effect "asinine", noting the distinction between short-term weather and long-term climate. Michael Daly criticized a mere delight in noting coincidences between events relating to Gore's favorite subject and severe winter weather." and environmentalist A. Siegel has called the jokes a "shallow observation" from "those who don't get that weather isn't climate". "Gore Effect" phenomena are "chalked up as coincidence", according to Joe Joyce, a weather forecaster and environmental reporter. Media Matters for America quoted Patrick J. Michaels, a sceptical climatologist and commentator with the libertarian Cato Institute in Washington with the observation that "the predictable distortion of extreme weather goes in both directions."

For several years now, skeptics have amusedly eyed a phenomenon known as “The Gore Effect” to half-seriously argue their case against global warming. […]The so-called Gore Effect happens when a global warming-related event, or appearance by the former vice president and climate change crusader, Al Gore, is marked by exceedingly cold weather or unseasonably winter weather. […] While there’s no scientific proof that The Gore Effect is anything more than a humorous coincidence, some climate skeptics say it may offer a snapshot of proof that the planet isn’t warming as quickly as some climate change advocates say.<templatestyles src="Module:Citation/CS1/styles.css"></templatestyles>
