Tucuruí Dam spillway, Tocantins River, Brazil (Eneida Castro). Brazilian researchers estimated in 2007 that methane from dams is responsible for around 4% of human-caused global warming. Greenhouse gases, primarily methane (CH4) and carbon dioxide (CO2), are emitted from the surface of the reservoir, at turbines and spillways, and for tens of kilometers downstream. Emissions are highest in hot climates. Captions and Photo source: ©© International Rivers
