Arctic and alpine tundra ecosystems are large reservoirs of organic carbon1,2 . Climate warming may stimulate ecosystem respiration and release carbon into the atmosphere3,4 . The magnitude and persistency of this stimulation and the environmental mechanisms that drive its variation remain uncertain5-7 . This hampers the accuracy of global land carbon-climate feedback projections7,8 . Here we synthesize 136 datasets from 56 open-top chamber in situ warming experiments located at 28 arctic and alpine tundra sites which have been running for less than 1 year up to 25 years...
