This document discusses geoengineering approaches to climate change, including both inadvertent and advertent modification of the climate. It presents three perspectives on the relationship between society and climate - that society dominates climate, is subordinate to climate, or can be in harmony with climate. It then summarizes various geoengineering schemes proposed to stop global warming, such as carbon sequestration and ocean iron fertilization. The document stresses that climate change impacts are systemic and challenges health, agriculture, forests, water resources, coastal areas, species and cultures. It argues that humans can plan ahead to anticipate climate impacts, unlike wildlife which can only react.
