In order to stabilize the planet’s climate and returned at least to the indicators of the last century, it will take several hundreds of years, experts are sure. But some changes are no longer possible prevent. It’s no secret that if the ice in Antarctica and Greenland will melt, the level of the oceans will change dramatically, and this will lead to irreversible climate change, and extreme frost in the North hemispheres can become the norm. So, it turned out that ice the cover in Antarctica melts ten times faster than 600 years ago. TO This conclusion was made by scientists from the UK and Australia. Data studies published in the journal Nature Geoscience. Researchers drilled a 364-meter well on James Island Ross. Having carried out a chemical analysis of ice from the surface and from the depth, Scientists have found that the average temperature for 600 years rose about 1.8 degrees. “The most intense melting ice began about 50 years ago, “said one of the authors research scientist from australian national university Nerily Ebram. According to him, due to an increase in the temperature norm melting ice has reached its maximum speed over the past thousand years. “With global warming, summer temperatures are increasing approaching the zero point at which the process begins melting ice. In such conditions, the slightest fluctuations in the direction temperature increases immediately entail large-scale melting ice cover of Antarctica, “added Ebram. The greatest The expert’s concern was caused by the fact that the warming process for the past centuries did not pass uniformly, but spasmodically. By the way, researchers recently found that under the ice of Antarctica There are several billion tons of hydrocarbons. Methane emit deep-seated microorganisms that feed the remains of ancient plants. By measuring the amount they produce methane, scientists have estimated that its reserves are under the Antarctic ice even higher than stocks at the bottom of the oceans. And if all of a sudden this amount of methane will break through the faults in the ice and fall into atmosphere, it threatens catastrophic climate change.
