Emissions of sulfur dioxide from the volcanic eruption at Bárðarbunga amounted to nearly 12 million tons.
Twelve million tons. That is more than the total emission of the dangerous gas over the whole of Europe in 2011, according to University of Iceland scientist, Sigurður Reynir Gíslason.
The Bárðarbungan (aka Holuhraun) eruption was the biggest eruption in Iceland since the ‘Skaftá Fires’ from 1783 to 1784, which spewed poisonous sulfur dioxide (SO2) over a large area of Europe. The eruption lasted for six months, from late August 2014 to late February 2015.
Sulfur dioxide is toxic in large amounts and can cause respiratory problems and irritation to eyes, nose and throat.

In light of the volcano’s history and considering the fact that a large part of the Bárðarbunga volcanic system lies under Vatnajökull glacier, a sub-glacial eruption is likely, according to Kristín Jónsdóttir, director of the Icelandic Met Office’s natural hazards division.

“One volcano in a short period of time produced more SO2 than the whole of Europe,” says J.H.
“Carbon dioxide is also produced by volcanic eruptions in similar quantities. How many volcanoes will it take to change the CO2 light bulb?
“During the 600 BC Solar Minimum three separate major volcanic eruptions devastated the earth’s climate for decades. Bárðarbunga may be the first of many major eruptions in this cycle.”
