What is the Asian Brown Cloud?Environmental Impact of the Asian Brown CloudThe report makes clear that atmospheric brown clouds (ABCs) interfere with the environment in a number of ways.Impact on Himalayan GlaciersThe Himalayan glaciers provide the source of many of Asia’s great rivers, with millions of people depending on them for food and water. Because ABCs increase atmospheric heating these glaciers are in retreat for the past number of decades. ABCs carry large amounts of soot and black carbon which are deposited on the glaciers, allowing them to absorb more of the sun’s heat and melt quicker.
ABC impact on AgricultureDimming induced by atmospheric brown clouds is considered the major cause of the changing pattern of rainfall in Asia, with decreasing rainfall in some parts while other parts experience intense floods. ABCs are interfering with centuries old monsoon patterns with disastrous consequences for food production. The large concentration of ozone in atmospheric brown clouds could decrease crop yields by as much as 20%.Health Effects of Asian Brown CloudAccording to the UNEP report a large part of the aerosol particulars that make up atmospheric brown clouds are the result of incomplete combustion of fossil fuels and biofuels. The health impact of these particles is an increase in cardiovascular effects, pulmonary illnesses and chronic respiratory problems. The report estimates that in India and China alone, ABCs result in over 330,000 excess deaths per year.
