The last glaciation, as the authors note, ended about 11 thousand years ago.
British Geophysics from Cardiff University has suggested a possible solution to the “problem of 100 thousand years.” It explains why the appearance on Earth every hundred thousand years of glacial periods.
Global cooling observed with a period of hundred thousand years, scientists associated with the absorption by the oceans of carbon dioxide from the atmosphere. At the present time, including due to anthropogenic factors, there is a reverse process — carbon dioxide is released from the water and contributing to the greenhouse effect.
To such conclusions experts came, examined the bottom of the ocean. It turned out that there preserved fossil organisms and species that occurred approximately every hundred thousand years, approximately the same high content of carbon dioxide.
A key role in the balance of carbon dioxide in water, the scientists took the algae, and the ice on the surface of the ocean compared with the cover. According to experts, is currently the Earth is in an interglacial period. The last glaciation, as the authors note, ended about 11 thousand years ago.
