Do volcanoes cause climate change?

Do volcanoes cause climate change or it the other way around?

Freysteinn Sigmundsson, a vulcanologist at the University of Iceland believes that climate change can impact eruptions. “Global warming melts ice and this can influence magmatic systems,” he told Reuters. The end of the Ice Age 10,000 years ago coincided with a surge in volcanic activity in Iceland, apparently because huge ice caps thinned and the land rose. “We believe the reduction of ice has not been important in triggering this latest eruption,” he said of Eyjafjallajokull. “The eruption is happening under a relatively small ice cap.”

But Steven Goddard writing in What’s Up with That suggests it is the other way around.

Not climate, but perhaps solar effects can impact geological changes in the earth’s crust and influence eruptions. It seems unlikely that a feedback loop from surface air conditions could work to change the earth’s crust.

Clouds and dust from volcanoes can surely affect weather and maybe even weather for a few years. Perhaps volcanoes can even change climate but I think the jury is out on that.
