Hacking the Earth

The document discusses the concept of "hacking the earth" through various geoengineering techniques to address climate change. It notes that while we know what needs to be done, we may not have enough time, and raises the question of how many people are willing to let die. The document outlines some possible geoengineering techniques and acknowledges that geoengineering would be the most complex simulation project ever. It also notes the enormous technical challenges as well as huge ethical and political challenges around issues like liability, control, and strategic misuse. It argues that the choice is between unintended consequences or unprecedented catastrophe, and that working on this issue is about responsibility rather than control. It closes by stating that this is where the work needs to start.
