Filling the Gap: High-latitude Volcanic Eruptions Also Have Global Impact

Volcanic eruptions always seize the attention of climate scientists, because the sulfate aerosols formed in the volcanic plumes may stay months to years in the stratosphere—the second layer of the Earth’s atmosphere—resulting in the increase of radiation reflection from the Sun back into space, and therefore cooling the Earth's lower atmosphere or troposphere in a long time period. It is traditionally believed that because of atmospheric circulation patterns, eruptions in the t
