reener green and bluer blue: Ocean poleward greening over the past two decades 更綠的綠，更藍的藍：過去二十年海洋極地綠化現(xiàn)象 ▲ 作者：Haipeng Zhao, Manfredi Manizza et al. ▲鏈接： https://www.science.org/doi/10.1126/science.adr9715 ▲ 摘要：盡管氣候變化導(dǎo)致的陸地綠化現(xiàn)象已有充分記載，海洋中的類似趨勢卻沒有被徹底研究�；谛l(wèi)星觀測的海洋葉綠素a（Chl）濃度數(shù)據(jù)，該研究展示了表層海洋在2003至2022年間呈現(xiàn)顯著的向極地綠化趨勢。 與此同時，北半球副熱帶海域葉綠素濃度持續(xù)下降。通過構(gòu)建不平等指數(shù)發(fā)現(xiàn)，這種葉綠素濃度的緯度差異在過去二十年持續(xù)擴大，在北半球表現(xiàn)尤為突出。 水溫上升可能是驅(qū)動葉綠素變化的主因。這種以海水"更綠的綠，更藍的藍"為標志的葉綠素分布失衡現(xiàn)象，可能通過營養(yǎng)級聯(lián)效應(yīng)影響高營養(yǎng)級生物，進而對沿海國家漁業(yè)與經(jīng)濟產(chǎn)生深遠影響。 ▲ Abstract：Although the global greening associated with climate change is well documented on land, similar trends in the ocean have not been thoroughly identified. Using satellite observations of ocean chlorophyll a (Chl) concentration, we show that the surface ocean experienced a poleward greening from 2003 to 2022. Contemporaneously, the subtropical regions of the Northern Hemisphere experienced a decrease in Chl. As such, the latitudinal disparity in Chl, as documented by an inequality index, has been increasing over the past two decades, particularly in the Northern Hemisphere. Rising water temperatures may primarily influence the Chl trends. The increasing Chl inequality—marked by “greener green and bluer blue” waters—has the potential to cascade to higher trophic levels, with implications for the fisheries and economies of coastal nations. |
