The world will experience the most catastrophic situation in the last 3 million years.
According to a new study by the University of Southampton, by 2025, the level of carbon dioxide in the Earth's atmosphere will be even higher than in the hottest periods of the last 3.3 million years.
Scientists have analyzed the chemical composition of small remains in the ocean sediments of the Caribbean Sea. These data allowed to determine the chemical composition of the atmosphere in the Pliocene.
The authors of the study focused on the isotopic composition of the pipe. This element is present in the membranes of single-celled organisms - foraminifera.
They do not exceed 0.5 mm in length and gradually accumulate on the seabed over millions of years. The isotope composition of the pipe depends on the acidity of the seawater, and the pH, in turn, indicates the concentration of atmospheric CO2.
