Skeptics of global climate change don’t want to recognize the obvious – the weather no longer throws surprises, but methodically changing.

For example, in the village of Tayat, which is located in the south of Krasnoyarsk edges, the whole of November was almost positive weather. First two official winter day thermometers show +5. This is never here did not have. The natives two years ago reported that no old omens do not work.
Scientists report that currently due to high Arctic glaciers began to melt actively. It leads to decrease in the reflectivity of the Earth, which is still warming up more. Underwater and underground methane reserves come out, shackled to date by the permafrost of the Siberian Arctic shelf. Methane in the atmosphere exacerbates the greenhouse the effect.
As a result of higher temperatures, glaciers will melt further faster, releasing even more methane. Thus, we have natural natural positive bond that warms up The earth is getting stronger and stronger. Last mass methane release in Earth’s atmosphere was about 12,000 years ago.
An international group of researchers from the United States and Russia has established that the thawing of permafrost in the Arctic Ocean is in no way connected with human activities. Permafrost melts as a result of heating very slowly – over several thousand years. However she already melted so much that methane seeping through the soil of the bottom, began to rise to the surface of the sea.
Record methane levels recorded by scientists at sea Laptev.
Russian-American group of scientists found that the Siberian Arctic shelf releases large quantities into the atmosphere methane. This partly confirms the predictions that melting ice can lead to a sharp increase in greenhouse gas concentrations in atmosphere of the planet.

A team of Russian and American researchers found that a large amount of methane leaves the underwater permafrost along the shelf of Eastern Siberia. In a work published in a journal Nature Geoscience, scientists describe their research. Scientists in For several years, measurements were made in the Laptev Sea and others areas along the shelf, using as a scientific platform in including fishing vessels.
The north of Russia borders the Arctic Ocean and the sea Laptev is a marginal water basin of the Arctic Ocean. Usually the Laptev Sea freezes in the winter and melts in the summer, even in summer, the water is so cold that the bottom of the sea remains frozen. It is believed that due to global warming, permafrost will melt and release huge amounts of methane, which will disaster for the Earth’s climate.
Permafrost in this region is really melting. Not less, according to the scientists involved in this study, melting of permafrost in the Arctic Ocean cannot be associated with human activity. The heating process is in progress. extremely slow and melts permafrost throughout thousand years. Only very recently the permafrost has melted so much that in the summer, methane began to seep through the soil of the bottom and rise to surface of the sea.
Researchers observed record levels of methane in the Laptev Sea in seawater (except for air samples, a sonar was also used to measure the density of water). Worse, it turned out that the level methane in water falls during storms, which means that the greenhouse gas is released into the atmosphere and exacerbates the effects of global warming.
Researchers note that their measurements contradict alarming forecasts claiming a strong methane release will soon add to an atmosphere of 50 billion tons of methane will cause a sharp rise in global temperatures and humanitarian disaster of unprecedented proportions. Instead scientists believe that methane will continue slowly rise from the bottom, and the rate of its entry into the atmosphere does not will increase. However, scientists fear that global warming can lead to stronger or longer storms in the Arctic Ocean, which will still increase output methane from sea water to the atmosphere.
