Gore and the climate change pledge

Al Gore has a strongly worded op-ed in the Times today on climate change.  It also previews the Live Earth concerts next week, and the pledge we will be asked to take:

Next Saturday, on all seven continents, the Live Earth concert will ask for the attention of humankind to begin a three-year campaign to make everyone on our planet aware of how we can solve the climate crisis in time to avoid catastrophe. Individuals must be a part of the solution. In the words of Buckminster Fuller, “If the success or failure of this planet, and of human beings, depended on how I am and what I do, how would I be? What would I do?”

Live Earth will offer an answer to this question by asking everyone who attends or listens to the concerts to sign a personal pledge to take specific steps to combat climate change. (More details about the pledge are available at algore.com.)
