The loss of Ozone in the Arctic figured out the record

VIVAnews -ozone layer is the layer which serves as the shield that protects life on Earth from harmful ultraviolet radiation. In recent weeks, unusual weather conditions have resulted in the depletion of the ozone layer in the Arctic region. Thinning of the times this happens is the worst.

As the informed, the concentration of ozone continue to be monitored by international agencies since the signing of the Montreal Protocol in 1987, which determines the boundaries of the production of chemical compounds, halocarbon containing chlorine and bromine and cause damage to the ozone in the stratosphere.

This time, according to researchers from Laboratorie Atmospheres, Milieux, Observation Spatiales, France, at the end of last March, the loss of the ozone layer has reached about 40 percent.

Quoted from Science Daily, April 11, 2011, the phenomenon of depletion of the ozone layer due to the extreme cold temperatures and winter stratosferik the length of which resulted in the destruction of ozone significantly. This condition is expected to continue until the spring.

As known, the destruction of ozone in the stratospheric polar moment of area occurred at temperatures down to the bottom of-80 degrees Celsius. At this temperature, clouds formed in the bottom of the stratospheric. Chemical reaction inside the compound of halocarbon kemundian change (which is not harmful to the ozone) being active compounds. The process leading to the destruction of ozone when sunlight illuminates the poles.

The ozone hole in Antarctica ' phenomenon ' is always going on there because the air temperature in the stratospheric polar South was very low in winter. However in the Arctic, on average, the temperature generally warmer.

Without the Montreal Protocol, ozone damage this year may be more severe. During the concentration of chlorine and bromine in the startosfir remains high, the thinning of the ozone layer, as this will return the kamili o. present in winter very extreme at the North Pole.

Of the trial, the researchers estimated, the new ozone layer could recover to the levels before the year 198 's in about the year 2045 until 2060 upcoming in North and South Pole around one or two decades earlier at the North Pole.
