POZNAN, Poland (AP) -- Climate campaigner Al Gore has urged negotiators at a U.N. global warming conference to free themselves of outdated ways of looking at the planet.
Gore says the delegates -- like everyone else -- are vulnerable to misperceptions, just as man once thought the sun revolved around the Earth.
He said scientists disproved that, beginning with the Polish astronomer Copernicus. Today, misperceptions may mislead us to believe there is little urgency to fight climate change. But scientists say quick action is needed to avoid catastrophic consequences.
Gore spoke Thursday after receiving an honorary doctorate from the Adam Mickiewicz University in Poznan, where a climate change conference was under way.
