They’re gonna blow. Research published in *Geology* shows the smallest
shifts in climate can increase the frequency of volcanic eruptions. By
examining Icelandic eruptions dating back 4,500 to 5,500 years, scientists
concluded that volcanic activity

as ice expanded and glaciers grew — and that even minor changes in ice
volume trigger more and bigger eruptions. While it’s not clear how they’re
connected, study authors suspect retreating glaciers ease pressure on the
Earth’s surface, resulting in freer-flowing magma. That’ll happen,
researchers believe, in the Pacific Northwest, southern South America and
Antarctica.
