The EC²LIPSE study provides an interdisciplinary assessment of space-based mitigation of the surface temperature rise associated with climate change. The mitigation, expected to be in place in 2060, uses a solar shield built from lunar materials and manufactured by robots, located near the Sun-Earth first Lagrangian point. The goal is to reduce the amount of incident solar radiation approximately 1.8% by 2060, returning surface temperatures to pre-industrial levels. EC²LIPSE is the result of an interdisciplinary student project carried out at the International Space University in Strasbourg, France. The study suggests one particular climate change mitigation approach to demonstrate the technical, political, and social considerations that should be examined in any such endeavor. Presented here is a high level summary of those findings in the technical, ecological, social, legal, political, financial, ethical, and public perception arenas. With potential 21st century climate change impacts becoming increasingly apparent, it is necessary for engineers, scientists, ethicists, politicians, lawyers, economists, and communication professionals to explore ways to achieve global cooperation to protect Earth from the most severe climate change fall-outs. The EC²LIPSE study illustrates an international and interdisciplinary mechanism to achieve such collaboration and encourage scholarly discourse on climate change mitigations beyond emissions reduction.
