The only thing he left out of the equation is nuclear – when abrupt climate change meets nuclear Armageddon, as it is right now in Ukraine.
Climate Change’s ‘Waking Giant’ to Set off Rash of Volcanic Eruptions, Tsunamis, Earthquakes?
Evidence from the end of the last Ice Age has already shown that the planet’s uneasy web of seismic faults – cracks in the crust like the one that runs along the Himalayas – are very sensitive to the small pressure changes brought by change in the climate. And a sensitive volcano or seismic faultline is a very dangerous one.
Climate change may play a critical role in triggering certain faults in certain places where they could kill a hell of a lot of people. These stress or strain variations – just the pressure of a handshake in geological terms – are perfectly capable of triggering a quake if that fault is ready to go (emphasis added).
