A 2017 study found that as glacial coverage increases, fewer volcanic eruptions occur. While it is not entirely understood why glacial coverage reduces volcanic activity, the researchers believe it is because glacial weight puts immense pressure on the earth’s surface and stifles the flow of magma. Earth’s glaciers are receding at an alarming rate–in some places, at six times the rate they were just ten years ago. Volcanoes pose an immense threat to those in their direct vicinity, and the toxic gas they release into the air can have disastrous effects worldwide. As scientists learn more about the importance of glaciers, the threat of glacial melt extends beyond just sea level rise.
