Global climate change isn't just expected to affect temperatures, there's a good chance it'll hurt what comes out of your tap.
"The major problem with climate change is not the climate, it's the water," Benedito Braga, president of the World Water Council, said on the sidelines of the Singapore International Water Week conference.
"The problems that will come with climate change will be felt in the water sector – that is longer droughts, more intense rainfall and flooding," he said.
A 2013 study by the National Aeronautics and Space Administration (NASA) projected that for every 1 degree Fahrenheit of carbon dioxide-induced warming, heavy rainfall – defined as months that receive an average of more than about 0.35 of an inch per day – will increase globally by 3.9 percent.
Global rainfall is not projected to change much, however, because moderate rainfall will decrease globally by 1.4 percent, it said.
At the same time, Braga is already concerned about how governments are managing water resources, especially in an era of growing urbanization across many developing markets, even before dealing with how climate change will affect resource management on a 50-100 year horizon.
"We are still far behind safe drinking water for most people and lack of sanitation," he said, noting many governments lack the political will to invest in water infrastructure.
According to the United Nations' 2013 Millennium Development Goals Report an estimated 768 million people still drew water from an unimproved source in 2011.
