Melting #Antarctic ice sheets may be causing larger volcanic eruptions

During #deglaciation, melting of kilometers-thick #IceSheets reduces the mass weighing down the land, which leads to #uplift. This alters the pressure inside #magma chambers lying below the Earth's surface, causing #volcanic eruptions.

Melting the #Marinoan Snowball Earth: The impact of #deglaciation duration on the sea-level history of continental margins. By Freya Morris et al. https://www.sciencedirect.com/science/article/pii/S0012821X24005648

"The #Cryogenian period is believed to have played a significant role in the emergence of complex, multicellular life, with animal and algal-based ecosystems beginning to appear once the ice sheets retreated"
