According to that report by 2050s, for Asia the fresh water accessibility is anticipated to diminish and climate change is anticipated to put extraordinary weights on natural resources alongside rapid urbanization. Furthermore, this report states that, 11 of the last twelve years between 1995 and 2006 have been the warmest years in the instrumental record of the Earth’s surface temperature with heat waves becoming much more frequent.

According to a study conducted by Asian Development Bank climate change impacts remain to cut up to 9% off the South Asian economy consistently before this present century's over, and the human and budgetary toll could be much higher if the harm from floods, droughts and other extraordinary climate occasions is incorporated.

The South Asian region displays an expansive scope of limits: in geography, from the tallest mountains to the biggest deltas to atolls scarcely above dimension; in precipitation, from parched grounds to tremendous fields subject to eccentric flooding; and in the earth, from chilly to tropical. Climate change projections for South Asia by the Intergovernmental Panel on Climate Change demonstrates that warming is probably going to be over the worldwide normal, that storm precipitation is probably going to increment, and that an expansion in the recurrence of extreme precipitation occasions is likely. Climate change impacts in the South Asia are in this manner various and multifaceted and further outcomes in social, monetary, and ecological harms.

A critical warming pattern of about 0.75ºC every century has been seen in past yearly mean temperatures over South Asia. As of late, quickened warming has been obvious, as found in the articulated warming pattern saw amid the decade 1998– 2007.

Recurrence demonstrating of surges and dry seasons indicates expanding pattern in forthcoming decades presenting genuine effects on agribusiness and animals, sustenance security, water assets, general wellbeing and financial status. There is high spatial inconstancy in precipitation and surface air temperatures along the tributaries of Indus basin. These spatial and transient varieties in temperature and precipitation specifically impact the hydrological cycles and trigger climatic boundaries.
