The cause of hot climatic phenomenon gradually appeared from 55 million years ago

Volcanoes that operate on Greenland and British islands have caused a warming climate 55 million years ago. Researchers at the University of Oregon (USA) have confirmed this hypothesis when analyzing marine geological and fossil data.

They confirmed that the release of carbon dioxide and methane in the atmosphere increased the temperature to 5 degrees Celsius at the surface of the tropical oceans and 6 degrees Celsius in the Arctic seas. These analyzes have for the first time demonstrated a direct relationship between volcanic and early stages of warming.

The so-called maximum Paleocene-Eocene temperature (Paleocene-Eocene Thermal Maxima, PETM) lasted for about 220 years and was very hot.

High levels of CO ₂ waste also increased the acidity of seawater, causing the extinction of many species.

The first volcanic eruptions began 61 million years ago and lasted for 6 million years. At this time, 10 million km3 of magma had surfaced on the surface of the Earth. Currently the lava flows at that time were clearly seen in Greenland and western Scotland.
