Most eruptions cause cooling via release of SO2, and some very short term local cooling with ash.
This eruption released a lot of water vapor because it was underwater, and water vapour is actually a very potent greenhouse gas.
So in general, volcanoes on land will cause cooling. I don't know if you can generalise underwater volcanoes the same way, it probably depends on how deep they are.
