Collection of some definitions of global catastrophic risks (GCRs)

Abstract

This work describes how global catastrophic risks (GCRs) lack sharp definition, but could be loosely defined as risks that could cause harm to global scales. GCRs are measured by level of fatalities and economic damage. A catastrophe that causes 10 million fatalities would count as a GCR, while a catastrophe that causes 10,000 would not. Some organizations measure GCRs by how greatly they could decrease global population. – AI-generated abstract.
