Simulations with a synchronously coupled atmosphere-ocean-vegetation model show that changes in vegetation cover during the mid-Holocene, some 6000 years ago, modify and amplify the climate system response to an enhanced seasonal cycle of solar insolation in the Northern Hemisphere both directly (primarily through the changes in surface albedo) and indirectly (through changes in oceanic temperature, sea-ice cover, and oceanic circulation). The model results indicate strong synergistic effects of changes in vegetation cover, ocean temperature, and sea ice at boreal latitudes, but in the subtropics, the atmosphere-vegetation feedback is most important. Moreover, a reduction of the thermohaline circulation in the Atlantic Ocean leads to a warming of the Southern Hemisphere.
使用同步耦合的大气-海洋-植被模型进行的模拟显示，约6000年前的全新世中期植被覆盖的变化，通过直接（主要是通过地表反照率的变化）和间接（通过海洋温度、海冰覆盖和海洋环流的变化）方式，改变并放大了气候系统对北半球太阳辐射增强的季节性周期的响应。模型结果表明，在北半球高纬度地区，植被覆盖、海洋温度和海冰变化具有很强的协同效应，但在亚热带地区，大气-植被反馈最为重要。此外，大西洋热盐环流的减弱导致南半球变暖。
