"June 16, 1883. The island of Krakatoa in the Java Straits disappears in a volcanic eruption so powerful it blots out the sun in many places around the world. Millions of tons of hydrogen sulfide gas are hurled high into the Earth’s atmosphere, where they remain for years. Tracking the ash clouds from Krakatoa alerts the scientific community for the first time to the existence of the jet streams."

"As climate change increasingly alters our lifestyles and embeds itself into our collective consciousness, geoengineering—in this case, humans playing volcano to replicate this cooling event—became a fascinating idea."

"Here we use the volcanic eruptions that inspired modern solar radiation management proposals as natural experiments to provide the first estimates, to our knowledge, of how the stratospheric sulfate aerosols created by the eruptions of El Chichón and Mount Pinatubo altered the quantity and quality of global sunlight, and how these changes in sunlight affected global crop yields."
