Climate has long been considered a factor in the collapse of the Angkor civilization, which flourished in Southeast Asia from the 9th to 15th centuries. Archaeological evidence suggests that Angkor was highly resilient to climate variability, but recent studies have highlighted the role of extreme climate events in its eventual demise.

One of the most devastating events in Angkor's history was a severe drought that occurred in the late 14th century. The drought is believed to have caused widespread crop failures, leading to famine and social unrest. This, combined with other factors such as political instability and warfare, contributed to the decline of Angkor and its eventual abandonment.

Other climate-related factors that may have contributed to Angkor's collapse include changes in rainfall patterns, flooding, and sea-level rise. These factors may have affected agricultural productivity, transportation networks, and the availability of resources, making it difficult for the civilization to sustain its large population.

While climate played a significant role in Angkor's decline, it is important to note that it was not the sole cause. A complex interplay of political, economic, social, and environmental factors led to the eventual collapse of this once-mighty civilization.
