Underground Gases and Climate Swings Linked to Ancient Mass Extinctions

Scientists propose that volatile gases emanating from deep within the earth could be responsible for extreme climate shifts leading to ancient mass extinctions. This theory draws parallels between geological upheaval and major biological crises spanning hundreds of millions of years. Furthermore, research exploring gas shales has revealed unique ecosystems, including rock-eating fungi and tardigrades, suggesting that life continues to adapt in extreme environments. These findings underscore the deep connection between planetary geochemistry, climate stability, and biodiversity.
