The Nobel laureate and former U.S. vice president spoke at a Fortune Forum fundraiser to draw attention to global warming, the Daily Mail reported Sunday. Attendees, who donated between $2,000 and $100,000 to the event, included celebrity activists Bob Geldof, Darryl Hannah and Jerry Hall.
Gore earned the ire of journalists by refusing to speak to them and he declined to mingle much with the glittery crowd that paid to hear him, the British newspaper reported.
"Many guests looked tired and began to talk among themselves during his speech. Heads began to twitch with tiredness," one attendee told the Mail.
A spokesman for Gore disputed the account, saying he was well received and dedicates part of his fees to the fight against global warming.
