Barriers islands in the Arctic make up nearly a quarter of the world's barrier islands, and they're more vulnerable to climate change than islands anywhere else in the world. The reason: melting of sea ice and the permafrost that buffers Arctic islands from waves have left them susceptible to constant pounding from storms.
Homelessness Defined. Homelessness is a temporary condition that people fall into when they cannot afford to pay for a place to live, or when their current home is unsafe or unstable.
The national rate of homelessness in 2015 fell to 17.7 homeless people per 10,000 people in the general population from 18.3 in 2014. The rates in individual states ranged from 111 in the D.C. to 7 in Mississippi.
