According to many scientists, global warming is irreversible—but its progress can be slowed, its impact managed. This program examines strategies, many of them in operation, designed to protect land and populations made vulnerable by rapidly rising worldwide temperatures. From life-saving weather forecast methods in Mozambique to fishery replenishment systems in Vietnam, a range of innovations are studied—but the focus is not only on the developing world. Detailing struggles against drought and violent climate in the United States, Australia, and the Netherlands, Be Prepared clearly shows that global warming recognizes no national boundaries.
