The complex relationship between Earth’s geology, its position in space, and climate fluctuations has shaped the history of our planet.
REPUBLIKA.CO.ID, JAKARTA – Recent scientific breakthroughs have revealed surprising connections between massive volcanic eruptions, the Earth’s astronomical cycles and drastic climate changes that have led to mass extinctions over the past 260 million years. These revelations provide a deep understanding of the complex relationships between Earth’s geology, its position in space, and the climate fluctuations that have shaped our planet’s history.
Researchers have found that continental basalt flooding (CFB), the largest volcanic eruption known to man, was a key driver of these ancient climate changes. These eruptions released enormous amounts of carbon dioxide and pushed Earth into an extreme greenhouse climate and near-lethal conditions.
The research, detailed in Earth-Science Reviews, indicates that CFB volcanic activity is a key moment in Earth’s geological history and often coincides with other catastrophic events such as oxygen depletion in the oceans and rapid global warming.
Even more interesting is the synchronicity of volcanic and climatic episodes with Earth’s astronomical cycles, which occur every 26 to 33 million years. This pattern is consistent with the shift in Earth’s orbit in the Solar System and the Milky Way, indicating the existence of cosmic interactions that influence Earth’s geology and climate.
“Although these ancient events are different from human-caused climate change in recent centuries, they underscore the long-standing impact of carbon dioxide emissions on global warming,” the research team, which included figures from New York University and the Carnegie Institute, said in Science , as reported A green planetSaturday (June 1, 2024).
Since the last of these eruptions occurred about 16 million years ago, this research not only explains past extinctions and climate changes, but also offers a new perspective on Earth’s geological and astronomical interdependence.
“Glimpses into our planet’s past remind us of the complex and often surprising relationships between the cosmos, the Earth, and the environments we fight to protect today,” the researchers said.
