Pries C E H, Castanha C, Porras R, et al. The whole-soil carbon flux in response to warming[J]. Science, 2017: eaal1319.
Today, I read this paper from Science.
The topic is interesting. It is about the response of soil to climate warming.
The conclusion is that if the temperature increases 4 degree, soil respiration will increase 34-37%. Sounds scary.
However, I really doubt about their experiment because HOW could they control the experiment.
Soil in different regions with different plant canopy will have different reactions. Besides, I wonder how much air temperature should increase to increase soil temperature at the depth of 100 cm. Furthermore, how could they ensure the soil pressure and density is exactly same with natural situations?
So many questions.
