Soil microbial respiration in arctic soil does not acclimate to temperature
Warming-induced release of CO2 from the large carbon (C) stores in arctic soils could accelerate climate change. However, declines in the response of soil respiration to warming in long-term experiments suggest that microbial activity acclimates to temperature, greatly reducing the potential for enh...

Warming-induced release of CO2 from the large carbon (C) stores in arctic soils could accelerate climate change.
