Climate Change Is Turning Arctic S Carbon Sinks Into Carbon Emitters
This has been the norm for tens of thousands of years. However, according to a study recently published in the journal Nature, this precedent may be about to change—if it hasn’t already. Emission data shows that the thawing of permafrost is turning these areas from carbon sinks into carbon emitters. Researchers found that if greenhouse gas emissions continue at their current rate (RCP 8.5), carbon dioxide “lost” from permafrost each winter could increase 41 percent by the end of the century....
