Temporary acceleration of the hydrological cycle in response to a CO2 rampdown

摘要: [1] Current studies of the impact climate change mitigation options tend to scale patterns precipitation linearly with surface temperature. Using model simulations, we show a nonlinear hydrological response transient global warming and substantial side effect mitigation. In an idealised representation action, where reverse trend warming, shows significant hysteresis behaviour due heat previously accumulated in ocean. Stabilising or reducing CO2 concentrations atmosphere is found temporarily strengthen cycle, while rainfall over some tropical subtropical regions. The drying under Amazon, Australia western Africa may intensify for decades after reductions. inertia ocean implies commitment cycle changes long stabilisation reduction atmospheric concentration.
