What would happen if it did not rain for 2 years?

A well-known fact is that water is crucial to our survival. We can go for about three weeks without food but only three days without water. So what would we do if it just stopped raining, not just for a day or two or even a season, but for two years or more? Our rivers would dry up, field crops would fail and our green and pleasant land would start to look like a dessert. Land can be irrigated, but it means using precious underground water reserves. California’s water woes are a good example of this narrative.

Under drought conditions we could bore for water at the lowest point of old rivers and streams to see if springs still existed. Drilling by the coast, just above sea level on sand dunes is another reliable way to find water.

People would have to move closer to the sources of fresh water like the Great Lakes and other fresh water reservoirs. Loch Ness in Scotland has more water, than all the rivers and lakes of England and Wales combined.

A drought is a period of drier-than-normal conditions that results in water-related problems. Precipitation rain or snow falls in uneven patterns across the globe. Dry periods can last for 10 years or more and good reference is the "Dust Bowl" of the 1930's when dust storms destroyed crops and farms. Groundwater, which is stored in aquifers below the surface of the Earth, is one of Earth’s most important natural resources.

The water levels in the aquifer that support a well does not always stay the same. Florida for instance, must be careful not to abuse it’s aquifer for salt water could invade the fresh water reservoirs and salty water being heavier than fresh water would settle in permanently. Needless to say this would be disastrous not only for Florida residents deprived of drinking water but it would end Florida’s prominence in the tourism industry causing billions in damages and the loss of livelihoods for millions of people. Climate change is the loaded gun waiting for a trigger to fire catastrophic weather pattern changes that could generate drought in the plains and torrential rains in low lying areas of the world all at the same time with unforeseen human consequences. The fragility of our environmental system is just beginning to be recognized and this awareness resulted in the Paris accord on Climate that Trump decided was not in the best interest of the United States to be a party to it.
