From NPR: "Welcome to the coldest capital city on earth — Ulaanbaatar, Mongolia — where the temperature can drop to minus 20 degrees Fahrenheit at night. The city's population has nearly tripled since 1989. Without infrastructure to service all 1.4 million people, residents off the electric grid are burning raw coal to stay warm.
The result? Winters with extreme air pollution."
