I tend to question the reason or cause that they are giving for the increase when there is obvious reasons like a migrating magnetic pole that is about to flip and also there is the slowing of Earths rotation that can be strongly related to the coming increase in the volcanic activity and strength. via Science Alert / Business Insider: A strong volcanic eruption in the Philippines forced over 50,000 people to evacuate and sent ash plumes over a mile into the sky on Tuesday morning. Meanwhile, an eruption at a Japanese ski resort north of Tokyo caused avalanches that killed one person and trapped many others on the mountain.

The key, according to the researchers, is the relationship between glacial ice
