Are you liking Rick Perry, who thinks climate science is a cult? If not, consider supporting the Tar Sands Action, a sit-in at the White House (and select spots around the nation) slated for August 20-September 3. Read Bill McKibben’s Washington Post op-ed! Sign the petition! Pressure Obama—who can block construction of the Keystone XL pipeline pumping oil from Canada to the Gulf of Mexico! (After all, what could go wrong with a 2,147 mile-long crude-oil pipeline?) Twitter! Get arrested!
