An army of 1,000 people trained by Al Gore to present his now-famous global warming slide show are taking the message to high schools, employee break rooms and civic centers around the country in an effort to infuse every nook an cranny of the American consciousness with knowledge about climate change - and what to do about it. An estimated 5,000 presentations have been given so far. Gore will speak to his "climate change messengers" in an Earth Day address to be broadcast live on the Internet today. The Oscar-winning "An Inconvenient Truth" is already credited with invigorating the movement to combat climate change. The trainees present the same slide show depicted in the movie, but add personal, local touches, and they can react to skeptics in the audience who challenge the facts.
