Ancient Wildfires in Godavari Valley Coalfield Reveal Clues About Earth’s Climate 250 Million Years Ago

Scientists studying ancient coal deposits in India’s Godavari Valley Coalfield have discovered evidence of massive wildfires that occurred nearly 250 million years ago, shedding new light on Earth’s prehistoric climate and environmental conditions during the Permian period.

The research was conducted by a team from the Birbal Sahni Institute of Palaeosciences, which analysed ancient charcoal fragments preserved within coal-bearing rock layers. According to the scientists, the findings suggest that widespread wildfires once swept through dense forests across the ancient Gondwana supercontinent, which included present-day India.

Researchers used advanced scientific methods such as Raman spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, and palynofacies analysis to study the molecular composition of the preserved charcoal. These techniques helped scientists identify traces of both low-intensity and high-intensity fires with greater precision than earlier methods.

The study indicates that unusually high atmospheric oxygen levels during the Permian era may have contributed to the spread and intensity of the fires. Scientists believe these wildfires played a major role in shaping vegetation patterns, carbon storage, and coal formation processes over millions of years.

The findings, published in the journal Geological Journal, are expected to improve scientific understanding of how ancient ecosystems responded to climate shifts and environmental stress. Researchers also noted that studying prehistoric wildfire activity could provide valuable insights into present-day climate change and the increasing frequency of extreme wildfire events across the world.
