A new study suggests that by 2050, sea-level rise will affect the homes of 300 million people worldwide.

According to Climate Central, a non-profit environmental organization led by scientists and journalists, global sea levels will rise between two and seven feet or more.

The threat will be more or less dramatic depending on how much warming pollution we will emit into the atmosphere, and how fast ice sheets in Antarctica and Greenland will melt.

As the volume of the world's oceans increases, the risk of permanent inundation or increased flooding will exponentially grow.

The digital elevation model developed by Climate Central helps us detect the areas of the planet that are more exposed to coastal flooding.

But there's more bad news.

The independent team believes that by 2100, the homes of 200 million people may very well sit permanently below the high tide line.

Climate Central says that coastal planning and the construction of levees and other defenses could minimize these threats. The relocation of properties should also be studied.

Asia Is In Trouble

The problems caused by sea-level rise will affect everyone. However, Asia will is at high risk, as millions of people live in low-lying coastal areas.

Climate Central predicts that Mainland China (Shangai), Bangladesh (Dhaka), India (Kolkata), Vietnam, Indonesia, and Thailand will suffer more floods than everybody else.

"But the danger of permanent inundation is not limited to Asia. In 19 countries, from Nigeria and Brazil to Egypt and the United Kingdom, land that is now home to at least one million people could fall permanently below the high tide line at the end of the century," concluded the organization.

And the residents of small island states may soon need to leave their homes.

For example, in the Marshall Islands and the Maldives, people will face saltwater intrusion into freshwater supplies and frequent flooding.

Eventually, some archipelago nations will disappear forever under rising sea levels.
