According to scientific media, an international team of scientists led by Professor Daniel Sigman, Professor of Geology and Geophysics at the University of Princeton, stated that the rise of the favorable phenomenon of the cold waters of the Antarctic sea rising to the surface of the sea
Dr. Sigman said: "We think we have found the answer," he said, adding that "Antarctic circulation in the Antarctic Ocean is increasing." The amount of CO2 released into the atmosphere has increased in the deep ocean, and the earth has warmed up.
The ocean plays a huge d CO2 pool as the dissolved carbon from the surface moves into the deep water due to the action of "biological pump" phytoplankton and so on.
This is mainly done in low oceanic latitudes,
The concentration of CO 2 in the atmosphere is greater than 260 ppm at the beginning of the Holocene, but it is higher than that. at the beginning of the Holocene. At the end of the Holocene, before the industrial revolution, there was an increase from about 20ppm to 280ppm
This is slightly lower than the current CO2 concentration of 400ppm due to the fact that there is no such thing. Using fossil fuels, it is thought that it has played an important role in keeping the temperature stable and preventing decline, Dr. Sigman said.
It is common for other interglacials to reduce the amount of CO2 and maintain the status quo.
The team badyzed the rate of nitrogenous elements of organic traces in the shells of the Antarctic Ocean, foraminifers and deep-sea coral fossils,
However, they do not have the same effect. have not revealed the cause of increased hatching
.
The researchers believe that the phenomenon that has been observed in the Holocene continues.
Dr. Sigman said: "As a result of Holocaust studies, it is important to understand the effects of using fossil fuels, Can be used to predict how the # 1 Upwelling of the Antarctic Ocean will change in the future,
