Listen, uh, nobody panic or anything, but it’s starting to look like over the last million years, natural climate change and the resulting sea-level rise might have increased the number of volcanic eruptions tenfold. But I’m sure that doesn’t mean that increasingly rapid human-caused climate change and sea-level rise will have a similar effect! I mean really, why would it?
Actually, the authors of this new study in the journal Geology have been very quick to say that even if human-made climate change were bumping up volcanic eruptions, we wouldn’t see the effects for centuries. But in the past, periods of rapid sea-level increase have led to drastic increases in volcanic activity. When shifts in Earth’s orbit caused warming and rapid glacial melting, volcanoes erupted five to 10 times as often — and the more rapid the warming, the more eruptions increased.
