Over the past three weeks Iceland has been hit with 40,000 earthquakes. It sits on the boundary of the Eurasian and North American tectonic plates, which are pulling apart, and is soon likely to see volcanic eruptions. This may be because we are in a solar minimum and the earth's crust is cooling and contracting. With all due respect to the sagacity of Greta et al., if you really want to play with fire, talk about cooling right now. See entry "Volcanoes and Solar Minima" below.
