So for increased explosivity risk, all that is needed is a very thick glacial coverage over a magma chamber. And the trigger happens when those glaciers melt in their trees. Antarctica is now experiencing this. North America, New Zealand, and Russia are now under a watch. And once volcanic activity starts, it will likely be attributed to long-term global warming due to greenhouse gas flows. So you can see a feedback. There's a positive feedback where global warming is causing the ice sheets to melt. As the ice sheets start to retreat, we expect volcanic activity to increase. When that increases, more greenhouse gases are released. As the release, more warming takes place and the process continues on and on. So we can see that there's feedback being created.
