Scientists reveal secrets about the Earth’s climate 335 million years ago

A team of researchers at the University of St. Andrews in Scotland has revealed the role of carbon dioxide in warming phenomena on Earth.

The Russia Today website stated that the team used fossils to determine the amount of change in carbon dioxide levels during the Carboniferous and Permian periods between 335 and 265 million years ago, in a period known as the “Late Geological Ice Age.” The team found that this era witnessed levels A continuous decline in carbon dioxide until it suddenly rose 294 million years ago due to a huge volcanic eruption, which led to the heating of the planet and the melting of ice.

The team said their research shows how carbon dioxide plays a pivotal role in regulating climate and environmental conditions on Earth.

Dr. Hanna Juricova, the lead researcher from the University of St. Andrews in Scotland, added that the end of the late geological ice age was a turning point in the evolution of life and the environment, which led to the emergence of reptiles, pointing out that this change was driven by carbon dioxide.

The team used chemical fingerprints preserved in the shells of ancient marine organisms, and by combining multiple chemical fingerprints, the team was able to calculate how much carbon dioxide was in Earth’s atmosphere in the past and how those levels changed.

Dr. James Ray, who participated in the study, the results of which were published in the journal Nature Geoscience, said that carbon dioxide emissions in the past caused significant global warming and rising sea levels, and if measures are not taken to reduce them, they will lead to this. again in the future.
