Is not the first day know about the phenomenon of global warming. However, given how long, according to scientists, this process goes, we had clearly feel his presence. According to the editors of the journal Science, for “maintaining the balance” may well answer the waters of the Pacific. The fact is that, despite the fact that the surface layers retain the temperature at approximately the same level, the depth of the ocean at the same time is cooled, generally negates global climate change.
Such data were received by experts from the Oceanographic Institute in woods hole and Harvard University.
“The climate is changing over time. This is a natural process.” — says one of the authors Peter Huybers, Professor of planetology and earth Sciences from Harvard University. “The water which is now at the bottom of the Pacific ocean, was on the surface before the start of the little ice age, in the IX-XII centuries. When the temperature began to decline, she became colder and denser, down to the bottom. Our goal was to develop a model of how the internal characteristics of the oceans respond to climate change on the surface”.
Scientists have created a computer simulation of these processes and she confirmed their suspicions. But it was not enough and they used meteorological data and measurements of the temperature of the deep water layers of the Pacific ocean, taken the 80-ies of the last century. After comparison of these parameters with modern was that the cold layers at a depth of two kilometers and deeper. And they continue to cool.
“The deeper layers compensate for about 30% of the heat absorbed by the oceans in the XX century. This is approximately the amount that is necessary to bring the ocean into equilibrium with the atmosphere. The temperature increases due to greenhouse gases, but the depths of the ocean compensate for this cooling water. Understanding these processes will allow to better understand the processes of global warming”.
