Мировое (глобальное) потепление на планете Земля - The ozone gap above Antarctica has reached(achieved) the record sizes

Antarctic

Ozone gap above Antarctica threateningly разрослась. According to the World meteorological organization (ВМО), recently it(she) has reached(achieved) the record sizes. Meanwhile the ozone cloud protects the ground from ultra-violet radiation which causes some kinds of a cancer.

The area captured by ozone anomaly, as of September, 25th of this year was equal 29,5 million square kilometers. In previous record to year - 2000, its(her) sizes made 29,4 million square kilometers.

As the news service of the United Nations transfers(transmits) on Wednesday, experts(auditeurs) consider(count), that expansion of an ozone gap is caused by presence at an atmosphere of a plenty of the substances destroying ozone, and unusually cold winter.

The international meteorological organization emphasizes, is spoken in the message, that the ozone gap appearing above Antarctica, is one of the most striking displays of change of a climate, informs "Interfax".

According to ВМО, deficiency of ozone in an atmosphere for October, first, 2006 has made 39,8 thousand tons. It on 200 tons is more, than in record 2000. The news service marks(celebrates), that owing to acceptance of the Montreal report it was possible to reduce considerably use озоноразрушающих substances, and the ozone cloud has started to be restored.

However, under forecasts of scientists, its(his) full restoration above Antarctic will occur(happen) not earlier than 2065 - for 15 years later, than was considered before. We shall remind, earlier it was informed, that the American research group, having studied(investigated) data of supervision for last 25 years, has come to conclusion, that the ozone cloud in a stratosphere outside polar regions has ceased утончаться in 1997, to the middle of a century thickness of an ozone cloud will reach(achieve) norm(rate). Still later two decades will disappear ozone gaps above poles of a planet.

Researchers of the different countries converge in opinion, that the ozone cloud outside of poles of a planet is gradually restored. By different estimations of normal thickness the blanket of a planet outside of poles will reach(achieve) by 2040-2060. As to an ozone gap above South Pole its(her) disappearance will borrow(occupy) more time, however it(she) nevertheless decreases.
