Scientists busy poring over more than a year of data from NASA's Orbiting Carbon Observatory-2 (OCO-2) mission are seeing patterns emerge as they seek answers to the science questions that drive the mission.
Earth's oceans and land cover are doing us a favor. As people burn fossil fuels and clear forests, only half of the carbon dioxide released stays in the atmosphere, warming and altering Earth's climate. The other half is ...
Scientists have discovered a surprising similarity between rivers and humans: both release more carbon dioxide when they work hard.
