Synchronous eruptions and deglaciation in Southern Hemisphere

Analyses of Antarctic ice cores indicate that an approximately 192-year series of halogen-rich volcanic eruptions occurred approximately 17,700 years ago and can be attributed to Mount Takahe in West Antarctica; the authors suggest that the halogen may have depleted stratospheric ozone concentrations over Antarctica, triggering a nearly synchronous deglaciation in the Southern Hemisphere that has been previously documented in paleoclimate records.
