UN: Ozone hole over the past ten years has not increased. Video. Photo

The ozone hole over the past ten years has not increased due to the coordinated international efforts made to protect the ozone layer that protects the Earth from ultraviolet radiation from the sun.

This is stated in the study prepared by the World Meteorological Organization (WMO) and the UN Environment Programme (UNEP) with the participation of about 300 scientists.

As highlighted in the report, the concentration of ozone in the global scale, as in the Arctic, as well as over Antarctica has not changed for the worse.

This is due to phase-out of chlorofluorocarbons (CFC),

Reducing the thickness of the ozone layer over the Arctic

Reducing the thickness of the ozone layer over the Arctic Scientists prove

An unusually long period of low temperatures this winter and spring has caused an unprecedented reduction in the thickness of the ozone layer over the Arctic. Studies show that the destruction of the ozone layer over the Arctic in 2011, comparable only with the appearance of the ozone hole over Antarctica in the mid-80s.

To study the loss in the ozone layer over the Arctic, scientists nine countries analyzed extensive data on daily observations of trace gases, clouds and ozone, meteorological data and atmospheric models. Scientists have noticed

The ozone hole is smaller

The ozone hole is less to save the planet

International efforts to reduce harmful emissions into the atmosphere, necessary to destroy the Earth's protective ozone layer, yielding first results. As scientists have found in New Zealand, the width of the ozone hole over Antarctica is slowly decreasing.

According to the measurements, the ozone layer will return to the state in which he was in the 198th year, by the 2050, if all the measures to control greenhouse gas emissions will continue. The width of the ozone layer in the stratosphere is only 25 km, but it plays an

After the storm there is more ozone holes

After the storm there is more ozone holes Scientists prove

As the number of storms and their intensity increased due to heating of the Earth, the ozone hole over populated areas of the planet away from the poles can be so much more. It means that people will be affected by a stronger ultraviolet radiation that causes skin cancer — a new marker of global warming.

Mechanism would work as follows. When heated planets cyclones and storms will allocate to the stratosphere to a height of 14 to 35 km more gaseous water, a greenhouse agent. Under appropriate

German scientist Markus Rex (Markus Rex) and his colleagues at the Institute for Polar and Marine Research Alfred Wegener (AWI) found that the destruction of the ozone layer over the Arctic is happening much faster than expected, due to the side effects of global warming. If the

The thinning of the ozone layer has changed ocean circulation

February 5, 2013. According to scientist J. Hopkins, a hole in the ozone layer over Antarctica is caused by changes in circulation waters the southern oceans. According to Hopkins, this phenomenon has the potential to change the amount of CO2 in the atmosphere and, ultimately, have an impact on the global change climate.

The study found out that the middle layer of water in the southern part of the subtropical oceans become "younger" as rising circumpolar waters were "older." Such features layers of water purchased with increased surface winds, which affect the strength of the thinning the ozone layer. A

The ozone layer over the Arctic dwindled to a record

Space

Geneva. April 5. INTERFAX.RU — thickness of the ozone layer over the Arctic has decreased to a record level due to chemicals in the atmosphere, according to a report by the World Meteorological Organization, the United Nations.

It is reported that the amount of ozone in the Arctic with the onset of winter has decreased by 40%, while in winter 2010 it was down to 30%. According to scientists, the main cause of ozone depletion in 2011 was the action of chemicals and an unusually cold winter. However, experts predict that by 2030, the level of ozone can

Record over the Arctic ozone layer has decreased

A record of ozone layer that protects the earth from solar radiation, fix the last few months over the Arctic. This is reported by foreign media, referring to the statement by the World meteorologicheskaoy organization.

"The ozone layer over the Arctic has reached an all time low this spring because of the presence of ozone-depleting substances in the atmosphere and a very cold winter, which was this year in the stratosphere," — said the WMO. With the onset of winter the ozone layer over the Arctic has decreased by 40 percent. Previously, the highest levels of ozone layer

Tales of the ozone hole

Winter came. This means that over the Arctic began to grow again the ozone hole. Last winter, she broke all records: was the largest in the entire 20-year history of observations and size equal to that of the Antarctic. What is dangerous ozone layer over the Arctic? And should I be afraid of him?

No one so far knows clearly what the ozone layer

Winter-2011 has given food for thought for Ecology and Meteorology: the first three months of the new year over the Arctic ozone hole appeared a gigantic area of 2 million square
