**Kolkata, India** – A new study led by the Indian Institute of Technology, Kharagpur, offers hope for the survival of tropical rainforests in the face of global warming. The research, published in the journal *Global and Planetary Change*, analyzed fossilized rainforest remnants from 56 million years ago, a period known as the Palaeocene-Eocene Thermal Maximum (PETM).
During the PETM, global carbon dioxide levels soared to levels comparable to those predicted for the future. Despite this extreme warming event, the ancient rainforests of what is now Western India, then a tropical island, not only survived but thrived.
The study, which included scientists from Calcutta University and the University of Western Ontario, found that increased rainfall during the PETM likely buffered the rising temperatures, creating a favorable environment for the ancient rainforest ecosystems.
“The rainfall-buffered temperature effect is a significant finding,” said Melinda K. Bera, a co-author and isotope expert. “It suggests that while warming may have an impact, factors like increased rainfall can play a vital role in mitigating those effects.”
The findings challenge previous warnings from the Intergovernmental Panel on Climate Change (IPCC) which suggested that unchecked carbon emissions could lead to the collapse of tropical rainforests by the end of the century.
While scientists still debate the future of these ecosystems, the study provides valuable insights into the resilience of tropical rainforests and the potential for natural mechanisms to mitigate climate change impacts.
