Convergence of global hydrothermal pattern leads to an increase in vegetation net primary productivity

Changes in terrestrial net primary productivity (NPP) with climate were thought to arise from the direct effects of temperature and precipitation on plant metabolism. However, the change of NPP may be due to the indirect effect of global hydrothermal pattern changes caused by climate change on veget...
