At first glance we might think that climate change would have no impact on earthquakes.
But a glacier a mile thick weighs quite a lot. And when that melts, the ground underneath can lift by as much as 100 metres. And that shift can be enough to trigger earthquakes and volcanoes (which can be incredibly sensitive to tiny changes to their external environment, constantly teetering on the edge of stability). And it’s happened before.
The world is a complex interconnected system that we do not fully understand. 100 years ago we had barely even discovered electricity and magnetism.
