气候变化对宏观经济增长具有重大影响。研究了温室气体和人为气溶胶通过改变年平均温度对经济的影响。然而，土地利用和土地覆盖变化（LULCC）的经济影响仍然是未知的，因为它对温度有生物地球化学和生物地球物理的影响，而后者因纬度和扰动地表类型而异。在这项工作中，基于耦合模式比对项目第6阶段的多模式模拟，发现了历史（1850-2014）LULCC对经济的生物地球化学和生物地球物理影响的对比。它们对AMT的综合影响导致大多数国家变暖，这对气候温暖的发展中经济体不利，但对气候寒冷的发达经济体有利。因此，全球经济不平等加剧了。除了由于综合影响而增加的AMT外，发展中经济体的日温度变异性增强，而发达经济体的日温度变异性减弱，这进一步恶化了全球经济不平等。历史土地利用通过生物地球物理和生物地球化学效应影响气候。它们对平均温度和极端温度的综合影响可能会损害经济上处于劣势的国家，但对富裕国家有利，这引发了平等问题。
Climate change has significant implications for macro-economic growth. The impacts of greenhouse gases and anthropogenic aerosols on economies via altered annual mean temperature (AMT) have been studied. However, the economic impact of land-use and land-cover change (LULCC) is still unknown because it has both biogeochemical and biogeophysical impacts on temperature and the latter differs in latitudes and disturbed land surface types. In this work, based on multi-model simulations from the Coupled Model Intercomparison Project Phase 6, contrasting influences of biogeochemical and biogeophysical impacts of historical (1850–2014) LULCC on economies are found. Their combined effects on AMT result in warming in most countries, which harms developing economies in warm climates but benefits developed economies in cold climates. Thus, global economic inequality is increased. Besides the increased AMT by the combined effects, day-to-day temperature variability is enhanced in developing economies but reduced in developed economies, which further deteriorates global economic inequality. Historical land use impacts climate by biogeophysical and biogeochemical effects. Their combined effects on mean and extreme temperature may harm economically disadvantaged countries but benefit those in rich countries, raising questions of equality.
