Pollution Taking a Toll on South Asian Monsoons

According to University of Maryland’s Professor Raghu Murtugudde, the astronomical pollution levels in the highly populated region of Southeast Asia pose a serious threat to the area’s annual monsoons.  Historically, the monsoons have lasted about four months each, beginning around June 1 and ending around October 3.  As a lifeline for South Asia’s population of roughly two billion, the monsoon proves vital for inhabitants’ sustenance and cultivation of crops.  Over the past century, however, the annual phenomenon has become less beneficial to the region as the total amount of rainfall had decreased by approximately 20 percent.  Murtugudde suggests that the onset of this transition is the region’s rapidly increasing pollution, which causes the continent to heat faster so that the heat contrast between the continent and the Indian Ocean has diminished, causing a significant amount of evaporated ocean water to simply pour back into the sea.

It seems that the only solution to this burgeoning problem is to completely obliterate the region’s pollution for decades, which would prove completely implausible.  It seems to me that the population only continues to expand while the South Asian landmass simply cannot sustain any more human development.
