In 2017, severe droughts contributed to the worst humanitarian crisis since World War Two

 Over the course of the 20th Century, global water use grew at more than twice the rate of population increase. Today, this dissonance is leading many cities – from Rome to Cape Town, Chennai to Lima – to ration water. Water crises have been ranked in the top five of the World Economic Forum's Global Risks by Impact list nearly every year since 2012. In 2017, severe droughts contributed to the worst humanitarian crisis since World War Two, when 20 million people across Africa and the Middle East were forced to leave their homes due to the accompanying food shortages and conflicts that erupted.

As you can see just from the 25 year drought in the western U.S., Climate change droughts (and flooding in other areas) likely is just going to get much worse over time. The western United States is on it's way to becoming a full desert from Colorado west, except for maybe a small area 10 to 20 miles inward along the coast from the Pacific Ocean where evaporated Moisture from the Ocean keeps this band of 10 to 20 miles inland wetter than further inland.

For example, my own deck was often wet every morning from about June through most of August here on the Northern California coast. However, now we appear to be going into a drier phase even here along the coast. However, the coastal forests are incredibly green much more than normal because of the moisture coming off the oceans especially at night for months now.
