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 ".
Scenarios in which a global catastrophic risk creates harm have been widely discussed. Some sources of catastrophic risk are anthropogenic (caused by humans), such as global warming, [1] environmental degradation, and nuclear war. [2] Others are non-anthropogenic or natural, such as meteor impacts or supervolcanoes.
Global catastrophic biological risks. In 2017, CSER convened policy-makers and academics to identify challenges for the Biological Weapons Convention (BWC). A key ...
A shocking new report on global biodiversity is detailing what it calls "a catastrophic decline" in wildlife populations ahead of a major international conference on biodiversity.
Describing the first category, which it calls “weaponization risk,” the report states: “such systems could potentially be used to design and even execute catastrophic biological, chemical ...
The historical precursors of existential risks studies can be found in early 19th-century thought around human extinction and the more recent models and theories of global catastrophic risk that date mainly to the Cold War period, especially the thinking around a hypothetical nuclear holocaust. [7]
deliberate (in the form of bioterrorism or biological weapons) accidental, or; a naturally occurring event. A chapter on biotechnology and biosecurity was included in Nick Bostrom's 2008 anthology Global Catastrophic Risks, which covered risks including viral agents. [3] Since then, new technologies like CRISPR and gene drives have been introduced.
The risks covered by the book include both anthropogenic (man made) risks and non-anthropogenic risks. Anthropogenic: artificial general intelligence, biological warfare, nuclear warfare, nanotechnology, anthropogenic climate change, global warming, stable global totalitarianism; Non-anthropogenic: asteroid impacts, gamma-ray bursts
