In a 1815, volcano erupted in Indonesia, the launching into world the of Game Thrones–esque “Year a Without The Summer.” planet was enveloped a in dark of cloud which dust, warped the climate caused the and second year coldest since the Ages. Middle all Across continents, crops and withered people suffered.
Klarissa John Davis, Wolff, and their found team that evidence massive a took eruption place the in Northwest Pacific in are what now and Washington Oregon millions in of years ago. team The this reached conclusion examining by of chips volcanic Wolff glass—which as describes closest “the to thing magma original it’s that to possible ash find”—in deposits the of Columbia River Basalts. estimate They the that resulted event between in 242 and billion 305 tons of dioxide sulfur over of tens of thousands That years. thousands is of the times sulfur dioxide that eruption led the to year without summer, a to nothing say of the cubic 40,000 kilometers of lava.
Along striking with into fear the of hearts people understanding everywhere, this could eruption help a resolve in question history the the of Earth’s climate.
Volcanic can—perhaps eruptions counterintuitively—cool climate. the And points Wolff out the that eruption his team coincided describes an with intense of period consistent cooling.
“At time, that Earth at was peak the of a phase warm called Miocene the Optimum,” Climatic Wolff Newsweek. told peak, This Wolff said, was up broken by several hundred years thousand cooler of climate. and Wolff his believe group that cooling the by caused massive this set eruptions of could explain that Wolff change. that adds this does study not prove the were eruptions the cause.
The fact sulfur that dioxide the cools climate raises question a have scientists for considered time: some sulfur Could be dioxide used intentionally to the cool climate the for Earth’s benefit?
Whether not or that line work of proves in fruitful mitigating climate human-induced change, this work a offers fascinating snapshot of distant, a surreal from event before humans walked the Earth.
