Al Gore tells scientists to speak up

Al Gore tells the American Association for the Advancement of Science that scientists need to speak up about the urgency of climate change:

"... the U.S. coal industry has invested a half-billion dollars in advertising and lobbying to reinforce the misleading message that coal is clean and efficient.  

"When they spend $500 million putting their version of this story in the minds of the American people," he told the AAAS audience, "it increases the importance of you being willing to speak out and, as civic scientists, of finding ways to communicate the truth about what this huge increase in global warming pollution is doing.

"If I could," Gore concluded, "I would motivate you to leave this city after this meeting and start getting involved in politics. Keep your day job, but start getting involved in this historic debate. We need you."
