High-Latitude Volcanoes Linked To El Niño-like Events, Study Suggests
High-Latitude Volcanoes Linked To El Niño-like Events, Study Suggests
Jan 17, 2024 3:36 PM

A new study suggests that largely uninvestigated high-latitude volcanoes might have a significant effect on global weather events.

A group of climate scientists and academics from the United States, Sweden and Norway found that volcanoes at higher-latitudes can have a major impact on climate and even trigger El Niño-like irregularities in the atmosphere. Using a climate model, the researchers discovered that large summer eruptions from high-latitude volcanoes cause hemispheric cooling and a weakening in the trade winds.

, but the same attention has never been given to the high-latitude volcanoes further away from the equator.

Active volcanoes at higher latitudes were never thought to be highly impactful on a global scale. Sinking air in these regions make it more difficult for volcano emissions to penetrate high into the stratosphere or spread globally.

, as their emissions far surpass those from small, brief eruptions. Scientists involved in the study say that future modeling studies of this nature will shine a brighter light on the way high-latitude volcanoes can significantly alter climate patterns.
