the following is an interview of an expert from WMO(world meteorology organization). he gives a introduction to the latest ozone hole. I did a dictation, but several sentences i cannot hear clearly. i have marked them with red color. if you figure them out, let me know and i will appreciate and thank you very much. let's make it together.

To explain the Antarctica ozone hole, we first have to recall that the ozone layer protects us against the harmful violet radiation from the sun. Without the ozone layer we will be subject to 17 times more intense of the violet radiation than we have today. The ozone hole, the Antarctic ozone hole is an annually recurring phenomenon that appears in the month of august, September and October. And at its first, in typically late September or early October. [1]The ozone between 12 and 20 kilometers in depth. This ozone destruction is caused by man-made gases. [2]This is so-called people circumstance. These gases are now [3]less than 1987. This gas has a long life time in the atmosphere and so they come down very slowly at the rate of only 1% per year. In addition that you have to recall that some so-called replacing compound. [4]The compound replace. Some of the compound are increasing rapidly in the atmosphere so we need to keep an close eye on the situation.
What is the situation of the ozone hole in 2009? In 2009, the ozone hole, in size and in depth, is pretty much evident compared the last 10 years. It is a bit more in 2006 and it is also the year we saw the largest ozone hole ever observed. As long as the ozone circumstances remain at high concentration in atmosphere, they expect the ozone hole to look [5]cured from one year to the next. And the healing process of the Antarctic ozone layer will be quite long because of the long life time gases in the atmosphere. Complete the coverage of the Antarctic ozone layer is expected from the year 2009 to 2015.
what is the connection between the ozone hole and climate change? There are several links between the Antarctic zone hole and climate change. First of all, we have to mention that the ozone depleting gases are also[6] important gases. This means that[7] facing this gases out does something good not only good for the ozone layer, but for the climate on our planet.
And actually, it turns out in 2010 quite the next year[8] the taste of ozone depleting gases will have been 5 times more efficient in preventing the climate warming than the target in the first [9]period from 2008 to 2015.
