A climate apocalypse (also called a climate dystopia and a climate-induced collapse, among other names) generally denotes a hypothetical scenario involving the global collapse of human civilization and potential human extinction as either a direct or indirect result of anthropogenic climate change. Many academics and researchers posit that in actuality, unless a major course correction is imminently implemented, some or all of the Earth will be rendered uninhabitable as a result of extreme temperatures, severe weather events, an inability to grow crops, and an altered composition of the Earth's atmosphere.
