The permafrost in the Arctic is thawing. Now a new study find that seventy percent of the current infrastructure in the Arctic in the next 30 years has a high potential to be affected by thawing permafrost. This despite if the climate change targets of the Paris Agreement is meet.
Volcanic activity primarily focuses at plate boundaries on Earth. But volcanoes can also form far away from plate boundaries due to plumes of hot material rising from the Earth’s deep interior. Eventually this material reaches the surface and breaks through the Earth’s crust to form a volcano – a so-called “hotspot”. Scientists now present a theory of how this type of hotspot activity can explain massive, past volcanic eruptions in Greenland and in the North Atlantic.
