Bangladesh
The country of Bangladesh is at the mouth of the Ganges, Meghna and Brahmaputra rivers, on the Bay of Bengal. Many of the country’s poorest people live on low-lying land to the South of the country, in areas vulnerable to flooding and tropical storms. These areas will become more at risk as sea levels rise.

The risk of flooding is also increased as ice melts in the glaciers in the Himalayas which feed the rivers. In 2004, the capital city of Dhaka was seriously flooded: dozens of people died and over 100,000 people became ill from using dirty water. That year, about 700 people were killed in floods in the country as a whole, and millions had to leave their homes.

New Orleans,   Louisiana USA
Climate change has been linked to an increase in extreme weather events, such as storms and hurricanes. The Gulf of Mexico and the Caribbean Sea already experience a "hurricane season." The city of New Orleans is built at the mouth of the Mississippi river on the Gulf coast. Most of the houses are on low-lying land, and the poorest housing is often in most vulnerable areas.

In 2005, the city was seriously flooded following Hurricane Katrina. Almost all of its population had to leave, and over 1,000 people were killed.
