Volcanic Eruptions and Astronomical Cycles Linked to Historical Climate Change, Study Reveals

A recent analysis published in the journal Earth-Science Reviews sheds light on the connection between large volcanic eruptions, astronomical cycles, and historical climate change. While human-induced greenhouse gas emissions are responsible for modern climate change, the study highlights that climate change in the Earth’s history was influenced by a different set of factors.

Key Findings:

Volcanic Eruptions in Earth’s History

The study reveals that large volcanic eruptions in the Earth’s past released significant amounts of carbon dioxide into the atmosphere. This resulted in extreme greenhouse climate warming, nearly causing mass extinctions and environmental crises. These volcanic events occurred cyclically, with a pattern of every 26 to 33 million years.

Notably, the study connects these volcanic eruptions to astronomical cycles in the solar system. The cycles coincide with critical changes in the orbits of planets, following a recurring pattern. The last wave of volcanic eruptions studied occurred approximately 16 million years ago.

Impact of Astronomical Cycles

The research suggests that geological processes on Earth, once believed to be primarily influenced by internal factors, are, in fact, influenced by astronomical cycles in the solar system and the Milky Way galaxy.

Researchers emphasize that their findings do not relate to the climate change observed in the 20th and 21st centuries, which is attributed to human activities. Instead, historical climate change was primarily driven by natural factors, such as volcanic eruptions and associated carbon emissions.

The analysis still supports the impact of carbon dioxide emissions on global warming. However, in the modern era, human actions are responsible for carbon emissions that trigger global warming, distinguishing it from historical climate changes driven by natural factors.

This study underscores the complex interplay between geological and astronomical factors in shaping the Earth’s climate history. While modern climate change is linked to human activity, the research provides valuable insights into past climate shifts caused by different mechanisms.
