Climate change has been a bonanza for historians and researchers.

Falling water levels in dams, lakes, or rivers reveal submerged civilisations and crimes. A good example is the discovery of human remains as the water level in Lake Mead and the Hoover Dam on the Arizona-Nevada border fell in 2022.

Think of the curiosity arising from the human remains. Who was that? How did he die? When? Falling river water levels have revealed remains of ancient civilisations in China on the Yangtze River and exposed sunken World War II (WWII) warships on the Danube River in Europe.
