Researchers at the Earth-Life Science Institute in Tokyo investigated the role of chemical weathering beneath ice sheets during ancient Snowball Earth glaciations. They proposed that these subglacial chemical reactions consumed significant amounts of atmospheric carbon dioxide, which contributed to extending the duration of these global ice ages.

Subsequent reports from multiple sources confirmed this finding, emphasizing that subglacial weathering played a key role in prolonging the ancient glaciations by reducing atmospheric CO₂ levels. This research provides new insights into Earth's climatic history and the mechanisms that influenced long-term global ice coverage.
