The terrestrial biosphere is a key component of the global carbon cycle and its carbon balance is strongly influenced by climate. Continuing environmental changes are thought to increase global terrestrial carbon uptake. But evidence is mounting that climate extremes such as droughts or storms can lead to a decrease in regional ecosystem carbon stocks and therefore have the potential to negate an expected increase in terrestrial carbon uptake. Here we explore the mechanisms and impacts of climate extremes on the terrestrial carbon cycle, and propose a pathway to improve our understanding of present and future impacts of climate extremes on the terrestrial carbon budget.
陆地生物圈是全球碳循环的关键组成部分，其碳平衡受气候的强烈影响。人们认为，持续的环境变化将增加全球陆地碳吸收。但越来越多的证据表明，干旱或风暴等气候极端事件可能导致区域生态系统碳储量减少，从而有可能抵消陆地碳吸收预期增加的影响。在这里，我们探讨了气候极端事件对陆地碳循环的影响机制，并提出了一条改善我们对气候极端事件对陆地碳预算当前和未来影响的理解的途径。
