Temperature dependence of spring carbon uptake in northern high latitudes during the past four decades
Abstract In the northern high latitudes, warmer spring temperatures generally lead to earlier leaf onsets, higher vegetation production, and enhanced spring carbon uptake. Yet, whether this positive linkage has diminished under climate change remains debated. Here, we used atmospheric CO 2 measureme...
