Global catastrophic risk

A global catastrophic risk or a doomsday scenario is a hypothetical event that could damage human well-being on a global scale,^[2] even endangering or destroying modern civilization.^[3] An event that could cause human extinction or permanently and drastically curtail humanity's existence or potential is known as an "existential risk."^[4]

Over the last two decades,^[when?] a number of academic and non-profit organizations have been established to research global catastrophic and existential risks, formulate potential mitigation measures and either advocate for or implement these measures.^[5]^[6]^[7]^[8]
