While I agree with the general thrust of the piece, many details seem wrong. Food shortages will not kill you.[1] Nor will mass migration per se. But the author omits global thermonuclear war--the biggest, most dangerous risk, as it always has been--being made more likely by climate change induced stresses. Water and/or electricity shortages and/or heat stress or wildfires or conflict may well kill millions who live in countries or states with incapable governments (those that are corrupt, or nepotistic, or otherwise have key personnel not selected for competence alone). The author seems to think "reserves" is a meaningful figure for metals and other minerals. Reserves is a figure for the amount that companies have found and that they are are prepared to go through the process of developing within (approximately) the next 20 years (the standard permitting, financing and construction timetable). When they get to 20 years' worth, companies stop looking. 1. I have lived through at least two food price supercycles, with peaks in the 1970s and the 2005-2008 period. Food price cycles are self-correcting. There is a lot of slack in the food production and distribution system - think of all the corn grown for e-85 gasoline, for instance.
