Many people used to believe that a volcanic eruption in Siberia was the cause of the climate disaster. However, new evidence shows that the world's climate is already changing. Researchers in Nature 》A new study published in the journal confirms that several super volcanic eruptions in eastern Australia may have helped accelerate climate change millions of years ago.
Researchers say the supereruption shook eastern Australia between 256 and 252 million years ago. These super eruptions may be an important introduction to the large-scale climate change the world was experiencing at that time.
During these eruptions, researchers believe that the eruption spewed large amounts of gas and volcanic ash into the atmosphere. Greenhouse gas emissions have always been the main cause of global temperature rise. The levels of gas released by these eruptions will easily play a role in the world's largest climate disaster. The researchers say the spread of the resulting ash is consistent with some of the largest volcanic eruptions we know.
In addition, researchers say evidence of eruptions and their sources can be found in volcanic erosion remains preserved in New England, New South Wales.
In addition, as the researchers pointed out, light colored volcanic ash layers can be found buried in sedimentary rocks. They found these layers in a large number of areas in New South Wales and even Queensland. More intriguing, however, is the scale of the supervolcano eruption. Their size makes sense, especially if they help cause the world's largest climate disaster.
The authors of the study believe that during these four million years, these volcanoes ejected at least 150000 cubic kilometers of material into northern New South Wales. For comparison, the deadly eruption of Mount St. Helens in 1980 ejected about 1 cubic kilometer of rock and material. Even the eruption of Mount Vesuvius in AD 79 ejected only about 3-4 cubic kilometers of material.
The researchers involved in the study are still in the conversation 》They published a detailed article on their findings. In the article, they shared more information about how these super volcanic eruptions played a role in causing the world's largest climate disaster to date.
