In particular, the Arctic Amplification for Iceland shows that warming is twice as fast as the rest of the world, compared to other Arctic regions like northern Siberia that are warming as much as seven times as fast. While the warming climate in Iceland may not be as fast as Siberia, it is still too high to keep polar ice sheets frozen.) When ice sheets melt rapidly, hazards can result in loss of infrastructure, livestock, and life. Specifically in Iceland, this includes at least two hazards influenced by climate change: jökulhlaups (glacial outburst floods) and even volcanic eruptions. Volcanic eruptions and climate change may sound like an odd connection at first, but it is very relevant in Iceland. Of the 41 active volcanic systems in Iceland, 12 of them are under Icelandic glaciers.) In addition, the most active volcano in Iceland, Grímsvötn, and Iceland’s largest volcanic system, Bárðarbunga, are both under ice. As the glaciers continue to melt due to increasing warming, volcanic pressure that has built up underneath is no longer constrained by the weight of the glacier, creating new pathways for magma migration. Thus, it is important to study how these unique volcanic systems have evolved through time." https://www.thearcticinstitute.org/keeping-eye-iceland-volcanoes-climate-change/
