Visoko nad ledenim kontinentom Antarktike vesoljsko plovilo Envisat agencije ESA opazuje dogajanje \u2013 in tisto, kar zaznavajo njegovi instrumenti, je precej zaskrbljujo\u010de.<\/p>\n<\/div>\n

Nizke temperature in kemikalije, ki jih proizvaja \u010dlovek, skupaj povzro\u010dajo nastanek \u2018luknje\u2019 v ozonskem pla\u0161\u010du. In zdi se, da bo leto\u0161nja ozonska luknja ena najve\u010djih v zgodovini.<\/p>\n

Do sredine avgusta 2005 se je njegova povr\u0161ina \u017ee pove\u010dala na 10 milijonov kvadratnih kilometrov \u2013 kar je pribli\u017eno enako velikosti Evrope. Pri\u010dakovalo se je, da se bo v septembru \u0161e dodatno raz\u0161irilo.<\/p>\n

Ozonska luknja je bila prvi\u010d odkrita sredi 80. let prej\u0161njega stoletja, sateliti agencije ESA pa jo neprekinjeno spremljajo \u017ee od leta 1995. Iz njihovih podatkov je razvidno, da sta bili v tem letnem \u010dasu ve\u010dji le ozonski luknji iz let 1996 in 2000.<\/p>\n

Ozon je oblika kisika. Majhne koli\u010dine ozona se nahajajo v stratosferi, med 20 in 50 km nad Zemljo.<\/p>\n

Na sre\u010do nas ozonski pla\u0161\u010d \u0161\u010diti pred son\u010dnim ultravijoli\u010dnim sevanjem, ki lahko povzro\u010di ko\u017enega raka. Vendar pa kemijske reakcije, v katerih sodeluje klor, ki ga proizvaja \u010dlovek, v visokih oblakih uni\u010dujejo ozon.<\/p>\n

Ko se pribli\u017euje polarna pomlad, kombinacija ponovno prisotne son\u010dne svetlobe in kemijskih reakcij klora povzro\u010di, da se molekule ozona razgradijo v kisik. Ena sama molekula klora lahko razgradi tiso\u010de molekul ozona.<\/p>\n

Podatki iz satelita Envisat so klju\u010dnega pomena za spremljanje sezonskih sprememb v tem za\u0161\u010ditnem sloju. Satelitski podatki se posredujejo slu\u017ebi za spremljanje in napovedovanje ozona v skoraj realnem \u010dasu, ki jo sestavlja ve\u010d kot 30 partnerjev iz 11 dr\u017eav.<\/p>","protected":false},"excerpt":{"rendered":"
