But Copernicus was right

BBC NEWS | World needs 'climate revolution'

Mr Ban said that economic concerns must not prevent developed countries from investing in elements of a "green economy", such as renewable energy, or from helping poorer nations to put their economic development onto a sustainable footing.

"We need a deal on climate change that will unleash a wave of investment in a green future," he told delegates at the opening session.

Referencing leading figures and events in Polish history, he called for a "new Copernican revolution" in industrial paradigms, and said the world "needs a global solidarity on climate change - the defining challenge of our era".

The Associated Press: Gore urges quick action on climate change

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(AP) — Climate campaigner Al Gore has urged negotiators at a U.N. global warming conference to free themselves of outdated ways of looking at the planet.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.
