Precipitation Mediates the Response of Carbon Cycle to Rising Temperature in the Mid-to-High Latitudes of the Northern Hemisphere.

When further examining how the spring carbon balance responds to temperature changes for wet and dry years respectively, we find that much higher temperature sensitivity of net spring CO 2 uptake (in absolute values) is observed during wet years (-1.05 ppm·°C -1 , p = 0.08) than dry years (-0.43 ppm·°C -1 , p = 0.09; Fig 2 ), although the correlations between the net spring CO 2 uptake and temperature are marginally significant for both.
