It appears that melting Antarctic sheets may result in larger volcanic eruptions This is due to the unloading of ice mass shifting pressure across vast chambers of magma.
"The researchers note that even if anthropogenic warming ceased immediately, the effects of ice mass unloading that the West Antarctic Rift System has already experienced will still affect volcanic behavior here for thousands of years to come."
