In this new perspective on how global warming will impact international relations across every continent, Gregory White, a professor of government, looks at climate-induced migration from the tropical regions of the world. Focusing on refugees fleeing Africa for Europe, White describes the enhanced security regimes that have been introduced in the rich North Atlantic countries, and the states that serve as transit points for migrants. The book highlights the wider implications of climate change on national sovereignty, which, in many cases, leads to the state increasing its influence over society.
