Climatic Severity Victims of Upstream Water Piracy Strongly Evidencing Inland Water-depletion Caused Global Warming vis-a-vis Cooling

Since the 80’s, the northwestern and the southwestern parts of the tropical Bangladesh located in the downstream Ganges basin have been having summer temperature above 109°F and winter temperature as low as 37°F. Every year people, particularly, the infants die from heat-and cold-related diseases and hospitals become packed-up with the victims of severe climatic condition. The objective of this research is to find the reason for the appearances of the extreme climate in certain parts of the country. Water bodies being reservoirs of heat, the condition of the rivers and other surface water resources has been examined. It is found that the continued water piracy at the upstream from the downstream Bangladesh Ganges discharge, the major source of water for the northwestern and southwestern parts, has depleted surface water resources and sunken the down the groundwater table. About 60% evaporation of the massively extracted groundwater to make up for the surface water shortage goes to merely increase the relative humidity without causing rainfall. Summer time lingering high temperature and high humidity cause the severity of summer weather. In the absence of the virgin surface water bodies, there is little room for storing heat for wintertime warming. The entire Ganges basin loses at least 10 times the heat it used to store in the water-abundant days. Summertime maximum temperature, HDDs and CDDs are negatively and wintertime minimum temperature is positive correlated with the decline of the Ganges’s discharge. Indian Government has to decommission her dams and barrages to mitigate the sufferings of the downstream people in Bangladesh. The greatest implication of this research is the accountability of the anthropogenic actions-caused depleting inland water bodies through storing, distribution via multi-channeling, irrigation, industrial and domestic use, for the occurrences of global heating vis-à-vis cooling and not CO₂ and other greenhouse gases accumulation in space. Immediate international actions are needed to end the episode.
