Lost villages, ancient ruins, WWII ships uncovered as extreme heat lowers water levels

Ancient relics, prehistoric treasures and medieval villages are among the underwater artifacts that have resurfaced as water levels around the world plunge because of drought.  

This year, the United States has been hit hard by major flooding events, water shortages and scorching temperatures. Multiple sets of human remains have resurfaced in Lake Mead as water levels continueto recede. 

Climate change affects everything from agriculture to energy transport, and many areas are not equipped with the infrastructure to deal with such extremes.
