Yes, but there have always been water shortage issues somewhere in the world. The problem today is population increase, population redistribution to cities, and to areas that cannot naturally support the populations, and  inadequate actions by politicians and water suppliers to provide adequate amounts of safe water for communities; however, it is now convenient to blame it all on global warming. Over many years, international organizations have thrown many billions in the water provision direction, with often limited permanent success. We have understood the technological and policy approaches to managing those problems for about 100 years. Water supply is not free, so people must be willing to pay and to conserve, and demand appropriate government action in their behalf.   The more recent wastewater to drinking water recycling technologies offer proven promise, if they are not overpriced by irrational regulatory requirements,  They are much cheaper than desalination, and more widely available.
