The Coffin in the Room: Catastrophic Impacts on Human Population
The Future of Humanity, Part 5
This is the fifth — and most distressing — post in my 7-part series on the future of humanity. The series starts here.
Climate projections versus population projections
There is a puzzling disconnect at the core of climate science between climate projections and population projections. Indeed, comparing the two, one might be forgiven for thinking that population scientists and climate scientists live in two completely different worlds.
On the one hand, climate scientists foretell a world of unprecedented disasters over the next decades and centuries: deadly heat, floods, droughts, mega-storms, abandoned coastlines, freshwater scarcity, food shortages, etc., etc. But on the other hand, population scientists at the UN are projecting a world population that continues to grow, largely driven by high birth rates in poorer countries (those most vulnerable to climate change impacts). In a report released in 2019, UN scientists projected that world population would rise from 7.9 billion today to 9.7 billion by 2050, before leveling off at nearly 11 billion around 2100 (source).
The disconnect between these two visions of humanity’s future is dizzying. To take…
