Can Evangeline Lilly, Ian Somerhalder, Malin Akerman, and Phillipe Cousteau succeed where others have failed? I don't know. I don't know who those people are. I'm guessing the last is Jacques' son, and Lilly is an actress, I'm pretty sure, but I'm not going to Google her.
These are some of the 24 (!!!) celebrities who have signed a letter to the president initiated by the Sierra Club. It quotes Obama's inaugural speech and then reads:
Your legacy as 44th president of the United States rests ﬁrmly on your leadership on climate disruption. Only the president has the power to lead an effort on the scale and with the urgency we need to phase out fossil fuels and lead America, and the world, in a clean energy revolution.
WE SUPPORT YOUR DEMONSTRATING THE STRONGEST RESOLVE IN FIGHTING THE CLIMATE CRISIS ON EVERY FRONT.
Emphasis and capitalization in the original because pay attention, Obama.
