将土地覆盖变化的影响添加到政府间气候变化专门委员会排放情景特别报告(SRES)中描述的A2和B1瞬变气候模拟中，导致2100年的区域气候与仅由大气SRES强迫造成的气候显著不同。A2情景中的农业扩张导致亚马逊地区显著额外变暖，高空气柱和附近海洋降温。这些以及其他对哈德利环流和季风环流的影响影响着温带气候。中纬度地区的农业扩张带来了降温，许多地区的日平均气温范围缩小。A2方案导致比B1方案更显著的变化，通常是相反的符号。
Adding the effects of changes in land cover to the A2 and B1 transient climate simulations described in the Special Report on Emissions Scenarios (SRES) by the Intergovernmental Panel on Climate Change leads to significantly different regional climates in 2100 as compared with climates resulting from atmospheric SRES forcings alone. Agricultural expansion in the A2 scenario results in significant additional warming over the Amazon and cooling of the upper air column and nearby oceans. These and other influences on the Hadley and monsoon circulations affect extratropical climates. Agricultural expansion in the mid-latitudes produces cooling and decreases in the mean daily temperature range over many areas. The A2 scenario results in more significant change, often of opposite sign, than does the B1 scenario.
