11. Global inundation
The eventual melting of both polar ice caps, which scientists predict is inevitable at the current rate of warming, would in the long-term result in a sea level rise of more than 120 feet. The loss of the Greenland ice sheet would cause an even greater rise.
12. Flooding of coastal communities
An estimated 145 million people live at altitudes within 3 feet of sea level. Even with a more conservative sea level rise estimate of 3 feet, these people will all be displaced by the end of the century, including in places like the Netherlands, the United States, South Asia, and China.
13. Florida under water
More than 1 million Florida homes are at risk of flooding by 2100, and many major coastal cities will be at least partially under water.
14. Bangladesh flooded
A 3-foot sea level rise would flood 20% of the landmass of Bangladesh, displacing an estimated 30 million people.
15. Widespread drought
By one estimate, available drinkable surface water per person will have fallen from 6,880 cubic yards in 1951 to 1,046 cubic yards by 2025.
