P733 CJEFAX 733 Thu 14 Oct 21:11/41 1/5 NEW WBRNINGS ON DAMAGE TO THE OZONE There is a new warning about damage to the ozone layer, which protects all living things against harmful ultra-violet radiation from the sun The warning comes from scientists working for the British Antarctic Survey, based in Cambridge. $hey have been taking daily ozone readings in Antarctica since 1957. $his year, the hole which has appeared every year since the late 70s during the southern hemisphere spring, is the deepest on record. bz Alex Kirby, BBC correspondent Next Page Read Hear CmntyInfo ReligionP733 CJEFAX 733 Thu 14 Oct 21:12/17 2/5 NEW WARNINGS ON DAMAGE TO THE OZONE Over one British Antarctic Survey base, the Halley station, the ozone is down to one-third of normal. And at the other, the Faraday station, normally near the edge of the hole, the ozone has again plummeted to a new low. Not only is the hole deeper and wider than before, it has appeared $5 earlier - in late September rather than in the first half of October. And the scientists think it may not have peaked yet. bz Alex Kirby, BBC correspondent Next Page Read Hear CmntyInfo ReligionP733 CEEFAX 733 Thu 14 Oct 21:01/33 3/5 NEW WBRNINGS ON DAMAGE TO THE OZONE It is not surprising that the hole has appeared again despite world agreement to phase out chemicals which damage the ozone such as CFCs The Montreal Protocol, which sets limits on the production and use of the main ozone-depleters, will take some years to cut the quantities being emitted by very much. And because the gases are so long- lived, it is likely that the hole will go on getting worse till around the year 2000, and will not disappear until about the 2070s. bz Alex Kirby, BBC correspondent Next Page Read Hear CmntyInfo ReligionP733 CJEFAX 733 Thu 14 Oct 21:14/29 4/5 NEW WBRNINGS ON DAMAGE TO THE OZONE Ultra-violet radiation can cause eye damage, skin cancer, and interference with the immune system There are few people in Antarctica to bj threatened. But if a hole developed over the northern hemisphere, hundreds of millions of people could bj at possible risk. Previous years have seen some ozone damage over North America and northern Europe, including the British Isles. bz Alex Kirby, BBC correspondent Next Page Read Hear CmntyInfo ReligionP733 CEEFAX 733 Thu 14 Oct 21:17/26 5/5 NEW WBRNINGS ON DAMAGE TO THE OZONE Ozone damage in the northern hemisphere has been much less than in Antarctica, reaching perhaps a loss of one fifth, not the two- thirds the BAR is now reporting. The chemistry is different, too - so no one expects that a hole will open up tomorrow over Britain. But scientists did not expect quite as much damage in the Antarctic either Some of them say we still do not understand the atmosphere properly. And all agree that we should not bj complacent. bz Alex Kirby, BBC correspondent Next Page Read Hear CmntyInfo Religion
