ABSTRACT
The world contains many small nations, ranging from prosperous European micro-states like San Marino or Liechtenstein, which were not absorbed during the formation of the modern nations of Europe, to isolated island groups in the oceans of the Third World. These small nations generally have far narrower economies than larger countries, sometimes dominated by a single industry such as tourism. They also have much less geographical diversity than larger nations, which means that in an era of changing climates they have far fewer choices. If the world becomes dramatically colder, the inhabitants of Nepal cannot move somewhere warmer without abandoning their country altogether.
