摘要：
Globally, over 15 billion forest trees, approximately 0.5% of the total, are cut down each year, and the global number has fallen by approximately 46% since the start of human civilization. The rates of forest loss in the Maritime Continent: Sumatra, the Malay Peninsula and Borneo in particular, are the highest. How may this expansive scale of accelerated deforestation alter the atmospheric wind and rainfall that penetrate beyond the local climate? Here we analyze observations and conduct ensemble model simulations to show that the recent decades of accelerated deforestation can force (i) a localized ascent of moist warm air over the northern Sumatra and the Malay Peninsula, (ii) descent of drier and cooler air over the Bay of Bengal and (iii) cyclonic wind over the western tropical Pacific and eastern Indian Ocean, thus weakening the south Asian summer monsoon. We project a significant, over 50% weakening of the south Asian summer monsoon should deforestation and urbanization continue unchecked in the next several decades – potentially threatening and/or fundamentally altering the livelihood of billions in a region of the world of increasing geopolitical importance.
