Not the first day it is known of such phenomenon as global warming. However considering how long, according to scientists, this process goes, we had to feel its presence obviously. As the editorial office of the Science magazine reports, for "maintenance of balance" waters of the Pacific Ocean can quite be responsible. The matter is that in spite of the fact that its superficial layers keep temperature at about one level, ocean depths in same it is a high time are cooled that in general levels global climate change.

"The climate changes eventually. It is natural process." & #8212; one of authors of work Peter Gyuybers, professor of planetology and sciences speaks about the earth from Harvard University. "The water which is now at the bottom of the Pacific Ocean was on a surface prior to the beginning of Small Ice Age, in the 9-12th centuries. When temperature began to decrease, it became colder and more dense, having fallen by a bottom. Our purpose was to develop model of how internal characteristics of oceans respond to climate changes on a surface".

Scientists created computer simulation of these processes and it confirmed their guesses. But it appeared insufficiently and they used the meteorological data and data of measurements of temperature of deep sheets of water of the Pacific Ocean taken the 80th years of last century. After comparison of these indicators with modern it turned out that cold layers are located at a depth of two kilometers and more deeply. And they continue to be cooled.

Such data were obtained by experts from Oceanographic institute in Woods-Houle and Harvard University.

"Deep layers compensate about 30% of heat absorbed by the World Ocean in the 20th century. It approximately that quantity which is necessary for reduction of the ocean in balance with the atmosphere. Air temperature grows because of greenhouse gases, but depths of the ocean compensate it by water cooling. Understanding of these processes will allow to understand better processes of global warming".
