Science study blames hot climate for Triassic extinction

(ANSA) - Vicenza, October 18 - A research team led by a Chinese scientist has found evidence that mass extinction in the Triassic period may have been caused by high temperatures on earth. A new study published in Science, conducted by a team coordinated by Yadong Sun, professor of geoscience at the University of China in Wuhan, found that one of the earth's most devastating mass extinctions - which happened at the beginning of the Triassic period, between 252 and 247 million years ago - may have been caused by lethally hot temperatures during a period of acute, natural global-warming. A series of powerful volcanic eruptions in Siberia caused a severe green-house effect, according to the study. "Global warming has played a important role and contributed numerous crises for life on earth," said Sun. According to the researchers' reconstruction, ocean water near the equator during the early Triassic period almost reached 40 degrees celsius, or about 10 to 15 degrees higher than current temperatures. At equatorial latitudes, oceans were nearly lifeless, and high temperatures near the equator led both to mass extinction and mass migration of animals and insects to northern and southern climes.
