Everyone debates what climate change does by 2100. David Archer models the next hundred thousand years.
The geophysicist’s long view (Princeton, 2009, Walter P. Kistler Award): a large fraction of fossil CO2 stays in the atmosphere for millennia. Keep burning and we may cancel the next ice age and eventually raise the oceans by 50 meters. The thaw is already locked in, and it will outlast everything humans have ever built.
The timescale is the point: it reframes climate from “our grandchildren’s problem” to a signature we’re leaving in deep time. Pairs with The Human Planet (the deep past) as the deep future.
