In general, the speed of the transition from ice age to melting, rather than the total amount of melting, predicted how intensely the volcanic eruptions increased, she said.
The study doesn't address whether modern-day climate change would have any impact on the frequency of volcanic eruptions, though in theory it's possible, Jegen said.
But even if anthropogenic, or human-caused, climate change
impacts volcanic eruptions, people wouldn't see the effect in this lifetime, because the volcanic activity doesn't occur immediately after the climate change, Jegen said.
"We predict there's a time lag of about 2,500 years," Jegen said. "So even if we change the climate, you wouldn't really expect anything to happen in the next few thousand years."
