Climate change and civilizational collapse refers to a hypothetical risk that the negative impacts of climate change might reduce global socioeconomic complexity to the point that complex human civilization effectively ends around the world, with humanity reduced to a less developed state.
An ice age would have a serious impact on civilization because vast areas of land (mainly in North America, Europe, and Asia) could become uninhabitable. Currently, the world is in an Interglacial period within a much older glacial event. The last glacial expansion ended about 10,000 years ago, and all civilizations evolved later than this.
[24] [25] Historians and archeologists believe that severe and long-lasting drought and a decline in trade with Egypt and Mesopotamia caused the collapse. [26] Evidence for earthquakes has also been discovered. Sea level changes are also found at two possible seaport sites along the Makran coast which are now inland.

Some of these have caused serious damage but were only local in scope—e.g. the Black Death may have resulted in the deaths of a third of Europe's population, [11] 10% of the global population at the time. [12] Some were global, but were not as severe—e.g. the 1918 influenza pandemic killed an estimated 3–6% of the world's population. [13]

Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
