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]

In the 21st century, 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]
