Drought, conflict and famine foreshadow the future

An email from Oxfam alerted me that this is happening:  An unprecedented number of people, 20 million in 4 African countries, are at risk of famine--the most since WWII. This is exactly the future that the climate maps of mid-century drought foretell. It is already underway. Where drought and political instability coincide, the people suffer and die. The climate factor is easily overlooked in the news. These are people who have contributed almost nothing to climate change. The call for $4.4 billion to avert this famine is tiny compared to military expenditures, but the world, and the U.S., has not responded.  Not long from now, as such droughts drive people to the coastal cities, they will be met by millions coming the other way, driven by rising seas.

    Not since World War II have more human beings been at risk from disease and starvation than at this very moment. On March 10th, Stephen O’Brien, under secretary-general of the United Nations for humanitarian affairs, informed the Security Council that 20 million people in three African countries—Nigeria, Somalia, and South Sudan—as well as in Yemen were likely to die if not provided with emergency food and medical aid. “We are at a critical point in history,” he declared. “Already at the beginning of the year we are facing the largest humanitarian crisis since the creation of the U.N.”  Without coordinated international action, he added, “people will simply starve to death [or] suffer and die from disease.”  ...
      Major famines have, of course, occurred before, but never in memory on such a scale in four places simultaneously. According to O’Brien, 7.3 million people are at risk in Yemen, 5.1 million in the Lake Chad area of northeastern Nigeria, 5 million in South Sudan, and 2.9 million in Somalia. In each of these countries, some lethal combination of war, persistent drought, and political instability is causing drastic cuts in essential food and water supplies. Of those 20 million people at risk of death, an estimated 1.4 million are young children.  ....
    Climate change is also intensifying the dangers faced by the poor and marginalized in another way.  As interior croplands turn to dust, ever more farmers are migrating to cities, especially coastal ones.  If you want a historical analogy, think of the great Dust Bowl migration of the “Okies” from the interior of the U.S. to the California coast in the 1930s. In today’s climate-change era, the only available housing such migrants are likely to find will be in vast and expanding shantytowns (or “informal settlements,” as they’re euphemistically called), often located in floodplains and low-lying coastal areas exposed to storm surges and sea-level rise. As global warming advances, the victims of water scarcity and desertification will be afflicted anew.  Those storm surges will destroy the most exposed parts of the coastal mega-cities in which they will be clustered. In other words, for the uprooted and desperate, there will be no escaping climate change.  As the latest IPCC report noted, “Poor people living in urban informal settlements, of which there are [already] about one billion worldwide, are particularly vulnerable to weather and climate effects.”
