“Will our species still exist in a thousand years?” asks the historian in a guest essay for The Economist
species still exist in a thousand years? Humans have been pootling around on this planet for a tiny slice of its existence, so it stands to reason that at some point in the future, it will be game over for our descendants.
Those cities and states fell into decline and their populations dispersed, partly because of changing climates: changes in rainfall patterns that included droughts that lasted for decades did not result in civilisational collapse—but they did add to existing pressures that made life more difficult, exacerbated rivalries, incentivised violence and reduced agricultural production. This time it is different.
Warming is not distributed evenly around the world, and the burden will fall most heavily on the poor in low-income countries in tropical regions.
Even if the Scylla of climate change is avoided, the Charybdis of natural and other man-made disasters might sweep most of us away. Few need reminding that the prospect of military confrontation is alive and well. Even if resolutions can be found for Ukraine, Taiwan and other potential flashpoints in the coming years, it would be brave to bet against the use of nuclear weapons in a global conflict over the coming centuries.
