Decline in the tropical carbon sinks


A new paper in Nature from Hubau et al. reports a decline in the tropical carbon sinks. This is an alarming finding since undisturbed old-grown tropical forests have been taking up about 15% of our greenhouse gas emissions. If the carbon sink capacity is  lost, which Hubau et al. predict might happen by 2035 in the Amazon forest, more CO2 will remain in the atmosphere thereby accelerating climate change. The findings of Hubau et al. are in stark contrast to global model projections, which mostly simulate an increase in the tropical carbon sink. See my comment in Nature and articles covering this very important topic in Carbon Brief and the Guardian.
