P\u00f5hja- ja L\u00f5unapoolusel on p\u00fcsivad j\u00e4\u00e4katteid olnud juba miljoneid aastaid. Kuid maailma tipus toimuvad praegu dramaatilised muutused. Uued satelliituuringud n\u00e4itavad, et Arktika merej\u00e4\u00e4 on h\u00f5renenud ja lagunenud.<\/p>\n<\/div>\n

23.\u201325. augustil 2006. aastal tehtud piltidel on esmakordselt n\u00e4ha p\u00fcsiva merej\u00e4\u00e4 dramaatilisi avausi. Need ulatuvad Svalbardi saarelt \u00fcle Venemaa Arktika kuni P\u00f5hjapooluseni \u2013 see ala on suurem kui Briti saared.<\/p>\n

ESA satelliidi Envisat radarpildidel on j\u00e4\u00e4augud kujutatud tumedate hallide ja mustade aladena. Satelliit Aqua n\u00e4itab purunenud j\u00e4\u00e4alasid kollase, oran\u017ei ja rohelise v\u00e4rviga. Kokku purunes augustikuiste tormide tagaj\u00e4rjel umbes 5\u201310 protsenti (kuni k\u00fcmnendik) suve \u00fcle elanud j\u00e4\u00e4st.<\/p>\n

\u201cSee olukord ei sarnane millegagi, mida on varasemate rekordiliselt v\u00e4hese j\u00e4\u00e4ga hooaegade jooksul t\u00e4heldatud,\u201d \u00fctles ESA ookeanide ja j\u00e4\u00e4 osakonna t\u00f6\u00f6taja Mark Drinkwater.<\/p>\n

Drinkwateri s\u00f5nul v\u00f5is j\u00e4\u00e4katte t\u00fckeldumine olla nii ulatuslik, et laev oleks v\u00f5inud kergesti purjetada Siberist P\u00f5hjanapani \u2013 mis oleks tavaliselt v\u00f5imatu. Alles viimaste n\u00e4dalate jooksul on meri hakanud uuesti j\u00e4\u00e4tuma.<\/p>\n

Viimase 25 aasta jooksul on satelliidid t\u00e4heldanud, et suvise sulamisperioodi jooksul on Arktika j\u00e4\u00e4pind \u00fcha enam kahanenud. 1980. aastate alguses h\u00f5lmas hilissuve j\u00e4\u00e4pind umbes 8 miljonit ruutkilomeetrit. Eelmisel aastal oli see pindala v\u00e4hem kui 5,5 miljonit ruutkilomeetrit. Neid muutusi peetakse \u00fcldiselt globaalse soojenemise tagaj\u00e4rjeks.<\/p>","protected":false},"excerpt":{"rendered":"
