Part of Bangladesh may disappear, 20 million people at risk

17 regions of the world are facing existential crisis due to the continuous rise in sea level due to climate change. Experts fear that by the end of the century, some parts or entire areas of these regions may disappear from the world map. Bangladesh is also on the list of vulnerable countries.

According to the report, the Intergovernmental Panel on Climate Change (IPCC) estimates that sea level may rise by 32 to 84 centimeters by 2100. As a result, low-lying island states, coastal cities and delta regions will be the most affected.

The study said that if the current trend continues, Bangladesh may lose about 17 percent of its total land area by the end of this century. As a result, about 20 million people will be at risk of being displaced.

According to experts, people's lives and livelihoods may be severely affected due to the spread of salinity in coastal areas, frequent cyclones, tidal surges and reduced agricultural production. This may also increase internal and international migration.

Small island states are most at risk.

Maldives: About 80 percent of the country's islands could become uninhabitable by 2050.

Tuvalu: About 95 percent of the area is at risk of flooding by 2100.

Kiribati: Sea levels are rising much faster than the global average.

Some islands in the Marshall Islands and Solomon Islands have already begun to partially disappear into the sea.

Not only developing countries, but also developed countries and historic cities are at risk.

Venice is sinking by 1-2 millimeters every year and faces repeated floods.

Miami is at risk of long-term waterlogging and flooding.

About a quarter of the Netherlands is below sea level and 60 percent of the country's population lives in flood-prone areas.

In addition, Nauru, Palau, Vanuatu, Seychelles, Samoa, Fiji and the Bahamas are also on the list of vulnerable areas.

Experts have warned that if these areas are lost, not only will the geographical map change, but also the global biodiversity, economy and population structure will change. Rising sea levels will threaten the homes, food security and livelihoods of millions of people.

Researchers have warned that future generations may have to face an even more dire reality if effective global action is not taken now to combat the effects of climate change.
