As Kano pointed out, much of the population is on the Ganges Delta. As a geologist, we learned early on that Deltas sink. Over the millennia, sediments deposit here. This results in additional weight being added. This causes the ground to sink. Other deltas such as at New Orleans and Venice are famously sinking as well. This may be a problem is dams are constructed and sediment no longer settles because if that happens, the ground will still continue to settle. Even without dams, building will tend to subside and may become vulnerable over timeSea levels have been rising slowly but they won't affect many areas except where the land is subsiding IMO. This will make them even more vulnerable to floods and tsunamis.
Since Bangladesh is (as Kano has pointed out) a river delta barely above sea level, the answer sought is probably along the lines of the coastal flooding originally predicted by Man Made Global Warming supporters about a third of a century ago.
Please note we didn't do what they said must be done to prevent catastrophe and there are still no boat tours of coastal skyscrapers.
(The coastal flooding was supposed to occur when the ice on land in Greenland and Antarctica melted.)
Most of Bangladesh is fairly low and flat, some below sea level. So as the glaciers melt, Bangladesh will flood.
Bangladesh has many problems, however I do not think climate change is one of them, their country is basically a river delta, built on sediments deposited by the Ganges river, and it is subsiding (slowly sinking) it is also being eroded by currents and tidal action.
What is needed is engineering the building of levees, of sophisticated design.
Well before 1970 monsoons were caused by changing winds. Now monsoons are caused by made made global warming. Heat waves before 1970 were caused by natural variability. Now heat waves are caused by man made global warming. Actually no matter what weather is occurring anywhere at this moment across the globe is absolute proof of man mad global warming.
I don't know what the effects are right now but I would expect them to be cataclysmic in the future and to force mass migration.

yes affects why thanks
