The most hazardous global warming risk for society at large is widespread loss of grain production because of a synchronized worldwide drought. It would be a colossal killer. It’s happened before, known as The Great Drought 142 years ago.
Unmistakably, droughts feed off global warming and world temps are heading up, not down. Thus, droughts are intensified by temperature increases. If the same conditions as the drought of 1876 recurs, it would likely be a nightmarish scenario.
Fortuitously, ever since The Great Drought of 142 years ago, droughts have been regional; e.g., when Russia experienced wheat shortages in 2011 as a result of extreme drought, which led to the Arab Spring, other countries like Brazil and the U.S. picked up the slack. The world continued spinning!
But, what if a severe drought hits the planet once again on a global basis like The Great Drought of the late 19th century? Then, what happens?
World population was only 1.4 billion when The Great Drought of 1876-78 killed 5.5 million in India alone, 50 million worldwide, but today’s world population is 4.5xs larger. Does this mean that global famine redux would bring in its wake 225 million deaths, or more?
Answer: First, hit the big red button that bonks the clarion bell in the public square to awaken people to the fact that the human footprint, in part and increasingly, negatively influences climate change for the first time since Adam and Eve. Given enough time, anthropogenic global warming…
