Scenarios of Global Catastrophic Risk
Responsible attention to the long-term future would not be complete without considering global catastrophic risk (GCR). Scenarios of anthropogenic GCR include: misuse or abuse of AI nuclear war runaway technologies ecosystem breakdown Scenarios of non-anthropogenic GCR include: plagues / pandemics calderas / supervolcanoes comets / asteroids solar flares / coronal mass ejections gamma ray burst contact with extraterrestrial life In the event of a GCR occurring amid BAU, BAU2, CT, or SW, significant fallout would follow in the aftermath and setback civilization on multiple levels, unless otherwise planned to withstand by design.
