Climate change caused by global warming is one of the major threats to the Tonle Sap lake. The 2016 Global Climate Risk Index rated Cambodia one of the top countries in terms of human losses due to extreme weather events. Rising temperatures, persistent drought, and delayed rainfall contributes significantly to the fall in water level of the lake, and exacerbates the overfishing issue by increasing the competition between locals who need to catch fish for a living. Furthermore, some of the forest fires that occur around the lake have occured in part due to the intensely hot weather. Hotter, drier weather is accompanied by more intense monsoons when the delayed wet season arrives, threatening the flooding cycle of the lake. This impacts the migration and spawning patterns of fish in the lake, affecting the amount of fish locals catch, and even leading to species disappearance in the lake.
