Abstract
Since the 80’s, the northwestern and the southweste rn 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 i nfants die from heat-and cold-related diseases and hospitals become packed-up with the victims of seve re climatic condition. The objective of this resear ch is to find the reason for the appearances of the extre me climate in certain parts of the country. Water b odies being reservoirs of heat, the condition of the rive rs and other surface water resources has been exami ned. It is found that the continued water piracy at the ups tream from the downstream Bangladesh Ganges discharge, the major source of water for the northw estern 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 shorta ge goes to merely increase the relative humidity without causing rainfall. Summer time lingering hig h temperature and high humidity cause the severity of summer weather. In the absence of the virgin surfac e water bodies, there is little room for storing he at for wintertime warming. The entire Ganges basin loses at least 10 times the heat it used to store in the w aterabundant 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 Governme nt has to decommission her dams and barrages to mitigate the sufferings of the downstream people in Bangladesh. The greatest implication of this resear ch is the accountability of the anthropogenic actio nscaused depleting inland water bodies through storin g, distribution via multi-channeling, irrigation, i ndustrial and domestic use, for the occurrences of global hea ting vis-a-vis cooling and not CO 2 and other greenhouse gases accumulation in space. Immediate internationa l actions are needed to end the episode.

Summary
Tropical climatic trend has changed for the northwest and southwest parts of the country. Located in the tropics, her Panchgarh, Syedpur, Jaypurhat, Bogra, Pabna, Ishwardi, form the northwest and the districts of Jessore, Kustia, Corresponding Author: Miah M Adel, Department of Chemistry and Physics, Mail Slot 4941, University of Arkansas at Pine Bluff, 1200 North University Drive, Pine Bluff, AR 71601. In the past few decades, climate-related sufferings of people and animals in these parts have increased causing even fatalities. Sketches of the reports on fatalities and morbidities due to severe climate in the northwest and southwest parts of the country are available in electronic media with due references to the print media.
