Broadcasting Corporation, BBC says that a group of scientists from the UK examined a number of volcanic sources in the oceans and concluded that their work could significantly change the entire marine ecosystem of the planet, it significantly raised the temperature, as well as increasing the concentration of sulfur dioxide gas. According to experts, the water near sources has a much higher acidity that kills all living within kilometers from the source.
Dr Jason Hall-Spencer said that in the case of large-scale oceanic volcanic eruptions, as it did in the past, our planet could lose up to 30% of marine biodiversity.
"Submarine volcanoes are constantly throwing bottles of gas by oxidizing all the neighboring regions, we see that the area around the volcanoes there are no representatives of the marine flora or fauna" — he says. Hall-Spencer said that underwater volcanoes can be compared to a kind of time machine that can very quickly have the same effect, which has a global warming of the oceans, atmospheric CO2 saturates.
Scientists say they have studied the work of underwater volcanoes in different parts of the world, in particular near the California coast in the Pacific Ocean, near the northern part of Europe in the Atlantic Ocean and near Australia. All volcanoes, as it turned out, deadly effect on the surrounding biodiversity.
According to Hall-Spencer, now the oceans already absorb about 50% of all greenhouse gas emissions by 2100 could lead to loss of biodiversity by 30-35% and an increase in pH by 0.4 points. The team notes that the last time such conditions in the oceans have been on our planet about 55 million years ago, but then the process of oxidation was 10,000 years old, and for the restoration took more than 125,000 years, yet it took 10 million years to the evolution of marine life to adapt to new features of the medium.
