Antarctic Volcanism

There are currently 25 active volcanoes (denoted by red triangles ),on the Antarctic plate, Mount Erebus has been continuously active since 1972

 The summer sun, acting on the resultant volcanic aerosol gases, causes depletion of the ozone layer, in winter the layer recovers. Misinterpretation (helped by Du Pont who had a new product to sell) of the term ‘aerosol gases‘ lead to the widespread “Ozone Hole” scare of the 1970s.

Showing the area of Western Antarctica where some limited melting is occurring (often reported); while the rest is cooling (not reported).

Geothermal heating under Marie Byrd Land, plus the Larson B & Ross Ice Shelves has caused some limited melting – & &

BTW, CO2 doesn’t cause volcanic eruptions & unlike CO2, volcanoes can also warm water and melt glaciers from below.

Rift basins exist in Ellsworth Land, linking GVIS and the Byrd Subglacial Basin, where elevated heat flow is likely to have influenced ice sheet development and stability.
