Trump’s Withdrawal From The Paris Agreement Actually Does Us A Favor

Donald Trump has done what Al Gore, Jim Hansen, climate scientists, the Sierra Club and the rest of the environmental movement could never do – make climate disruption breaking cable TV news. Trump’s histrionic, largely symbolic and recklessly self-destructive decision to abandon the Paris Climate Agreement means, among other things, that far more Americans know about the Paris Climate agreement this morning than 24 hours ago. Never has climate dominated a news cycle as it did yesterday – even when the Paris Agreement was signed by all of the world, (Nicaragua and Syria excepted). Trump did this by providing the climate crisis with what it lacked – a single villain. He has now cast himself, for most of the global community, as a James Bond style villain, a Dr. No or Goldfinger, plotting global destruction for personal power and gain. But he is, in reality, President of the United States – not a character in a movie. […]

Scott Pruitt Should Not Be Head Of The EPA

Like all Americans, I count on the U.S. Environmental Protection Agency (EPA) to ensure that my family’s water is safe to drink and our air is safe to breathe. That’s why I’m horrified that Donald Trump has nominated sworn enemy of the EPA, Oklahoma Attorney General Scott Pruitt, to be the agency’s top dog. This week the Sierra Club released two new videos, which you can see below, that paint a disturbing picture of just how unfit he is to serve as EPA Administrator. Just this week we learned that Pruitt, thanks to his super PAC, could have continued to accept money from the fossil fuel industry even if he’s confirmed as EPA Administrator ? Pruitt indicated he would shut down this super PAC after negative coverage in the press. Pruitt and his industry supporters haven’t stopped, though. Recently, yet another secretive special interest group able to take unlimited and anonymous money from fossil fuel interests and others is raising serious money to ensure Pruitt’s confirmation. […]
