How Does Climate Change Affect volcanic Eruption? Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. Injected ash falls rapidly from the stratosphere -- most of it is removed within several days to weeks -- and has little impact on climate change.
While a relationship between climate and volcanism might seem counterintuitive, it turns out that pressure exerted by thick glaciers on the Earth's crust — what geologists call "surface loading" — has an impact on the flow of magma below the surface.
