Earth's Ecosystems Still Soaking Up Half of Human Carbon Emissions

Even as humans emit ever more carbon dioxide into the atmosphere, Earth's ecosystems are still sequestering about half, according to new research in Nature. The study finds that the planet's oceans, forests, and other vegetation have stepped into overdrive to deal with the influx of carbon emitted from burning fossil fuels, but notes that this doesn't come without a price, including the acidification of the oceans.

"We're already seeing climate change happen despite the fact that only half of fossil fuel emissions stay in the atmosphere while the other half is drawn down by the land biosphere and oceans," co-author Caroline Alden with the University of Colorado, Boulder said in a press release. "If natural sinks saturate as models predict, the impact of human emissions on atmospheric CO2 will double."
