Greenhouse gas 'bookkeeping' turned on its head

For the first time scientists have looked at the net balance of the three major greenhouse gases—carbon dioxide, methane, and nitrous oxide—for every region of Earth's landmasses. They found surprisingly, that human-induced emissions of methane and nitrous oxide from ecosystems overwhelmingly surpass the ability of the land to soak up carbon dioxide emissions, which makes the terrestrial biosphere a contributor to climate change. The results published in the March 10, 2016, Nature, r
