Secret Soviet Base Hid Climate-Changing Volcanoes

Four volcanoes in a straight line on a remote Russian island—once a secret Soviet sub base—just got outed as the source of a climate-altering eruption 200 years ago! Simushir Island, part of the Kuril chain, was so off-the-grid that scientists only just linked its Zavaritzki volcano to the mysterious 1831 global cooling event. Wild to think a hidden military base and a volcanic blast could literally change the world’s weather! #Volcanoes #EarthFromSpace #KurilIslands #Science
