Satellites are giving us a commanding view of Earth’s carbon cycle

New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.

Global stocktake shows the 43 greenhouse gases driving global warming

While the gases most responsible for global warming - carbon dioxide, methane and nitrous oxide - continue to climb, other industrial greenhouse gases are being brought gradually under control.

Land carbon storage swelled in the Little Ice Age, which bodes ill for the future

When temperatures dipped between 1500 and 1750, the world’s landscapes responded by storing more carbon. Now, with temperatures climbing, it’s possible they will do the opposite and release even more.
