Italian physicist Antonio Zicchi recently proposed that the extinction of the dinosaurs was likely caused by a large-scale underwater volcanic eruption.
Professor Qi Jiqi believes that a series of large-scale volcanic eruptions occurred underwater at the end of the Cretaceous period, affecting the thermal balance of the ocean and subsequently causing changes in the terrestrial climate. This, in turn, impacted the survival of animals such as dinosaurs that required large amounts of food. His reasoning is that the impacts of modern submarine volcanic eruptions on the ocean and atmosphere are well-known, although their extent is far less than that of the submarine volcanic eruptions that occurred 65 million years ago.
Professor Qi Jiqi believes that in the past, the scientific community knew very little about submarine volcanic eruptions, and now there is a need for in-depth research into this phenomenon that seriously impacts the Earth's environment. He cited the example of Greenland, which once boasted lush vegetation, but after a global shift in ocean temperature balance, cold ocean currents changed direction and passed through Greenland, transforming this large island into an ice-covered land. This is a classic example of the enormous impact of ocean temperature balance changes on climate. Submarine volcanic activity is a significant factor influencing ocean temperature balance changes. Therefore, Professor Qi Jiqi believes that the changes in ocean temperature balance caused by large-scale submarine volcanic eruptions should be considered an important reference factor in the study of the extinction of dinosaurs.
