Activists to Obama: Stop leasing public land to take out oil, gas, coal

Public lands in the United States hold up to 450 billion tons of potential carbon emissions, in places like the Powder River Basin, home to massive coal deposits, or in offshore petroleum. If, over time, all of these emissions are released, it would be catastrophic for the climate. A new campaign is pressing President Obama to keep them in the ground forever.
