\u017de od leta 1985 znanstveniki spremljajo luknjo v ozonskem pla\u0161\u010du visoko nad Antarktiko. Upali so, da se bo ozonska luknja postopoma zmanj\u0161evala, vendar so najnovej\u0161i podatki s satelitov Envisat agencije ESA pokazali najve\u010djo izgubo ozona doslej.<\/p>\n<\/div>\n

Meritve, opravljene 2. oktobra, so pokazale zmanj\u0161anje za 40 milijonov ton, kar je preseglo prej\u0161nji rekord iz leta 2000. Poleg tega leto\u0161nja ozonska luknja pokriva povr\u0161ino 28 milijonov kvadratnih kilometrov, kar je skoraj enako velika kot luknja iz leta 2000. Tudi globina ozonske luknje se lahko primerja s prej\u0161njimi rekordnimi vrednostmi.<\/p>\n

\u201cTak\u0161en znaten upad ozona zahteva zelo nizke temperature v stratosferi v kombinaciji s son\u010dnim sevanjem,\u201d je dejal znanstvenik agencije ESA Claus Zehner. \u201cLetosni izjemen upad ozona je mogo\u010de pojasniti s temperaturami nad Antarktiko, ki so dosegle pribli\u017eno minus 92 stopinj Celzija \u2013 to je najni\u017eja temperatura, zabele\u017eena na tem obmo\u010dju od leta 1979.\u201d<\/p>\n

Zmanj\u0161anje ozonskega pla\u0161\u010da nad Ju\u017enim polom<\/figcaption><\/figure>\n

Ozon je oblika kisika v plinastem stanju. Oblikuje plast na vi\u0161ini 25\u201340 km nad Zemljo v obmo\u010dju, znanem kot stratosfera. Ozonski pla\u0161\u010d je pomemben, ker zadr\u017euje \u0161kodljive ultravijoli\u010dne \u017earke Sonca. Ti \u017earki pove\u010dujejo tveganje za nastanek ko\u017enega raka in sive mrene ter vplivajo na morsko \u017eivljenje.<\/p>\n

Red\u010denje ozonskega pla\u0161\u010da povzro\u010dajo onesna\u017eevala, ki jih ustvarja \u010dlovek, na primer klor, ki ostajajo v atmosferi ve\u010d let. Ko pride polarna pomlad, son\u010dna svetloba spro\u0161\u010da klor, ujet v visokih oblakih. Klor nato hitro uni\u010di ozon.<\/p>\n

Ta luknja obi\u010dajno traja do novembra ali decembra, ko se zrak z nizko vsebnostjo ozona nad Antarktiko za\u010dne me\u0161ati z zrakom z visoko vsebnostjo ozona iz zunanjega okolja.<\/p>","protected":false},"excerpt":{"rendered":"
