Add another prediction to the list of devastating effects of global warming: Scientists say, it is almost certain that global warming will drive an uptick in waterborne diseases around the world. Heavier rainfalls are one of the broadly accepted effects of climate change, reports the Washington Post. More rain will lead to sewage overflows; contaminated drinking water and seafood; bacteria, parasite and algae blooms; and more disease-carrying mosquitoes.
The 950 U.S. cities and towns that have "combined sewer systems" will be hit especially hard. The out-dated storm water and sewage pipes will not be able to handle the volume of increased rainfalls, causing raw sewage to spill into waterways.
