"Keystone XL pipeline foes have tried petitioning the government, grabbing media attention and filing lawsuits. Now, with the southern leg of the pipeline under construction, they’re turning to civil disobedience -- and actress Daryl Hannah."

"America is unique when it comes to giving a platform to climate deniers and skeptics. According to a new analysis of data released last year, American newspapers are far more likely to publish uncontested claims from climate deniers, many of whom challenge whether the planet is warming at all and are 'almost exclusively found' in the U.S. media. The study was published in the journal Environmental Research Letters."

"Rachel Carson wasn't someone you'd expect to spark a movement. She was a quiet, petite woman who grew up poor, lived most of her life with her mother and relished solitary walks along the beach, watching birds and fish. Yet 50 years ago Thursday, this marine biologist published Silent Spring, widely credited with spurring the modern environmental movement."
