Europ\u0105 u\u017eklupusios kar\u0161\u010dio bangos \u0161i\u0105 vasar\u0105 vis labiau veikia Alpi\u0173 ledynus, o ypa\u010d \u0160veicarijoje sniego danga kai kur i\u0161tirpo gerokai anks\u010diau nei \u012fprasta. Mokslininkai pa\u017eymi, kad tai rei\u0161kia ilgesn\u012f laik\u0105, kai saul\u0117 tiesiogiai \u0161ildo led\u0105, tod\u0117l tirpsmas \u012fsib\u0117g\u0117ja dar grei\u010diau.<\/p>\n
\u0160veicarijos ledynai yra svarbi Europos vandens sistemos dalis: jie papildo upes, prisideda prie geriamojo vandens tiekimo, \u017eem\u0117s \u016bkio poreiki\u0173 ir hidroenergijos gamybos. Kai \u017eiem\u0105 sukauptas sniegas nutirpsta per anksti, ledynas netenka nat\u016bralios apsaugos, o prarastas ledas per vien\u0105 sezon\u0105 nebeatsistato.<\/p>\n
\u201eDabar esame situacijoje, kuri paprastai susiklosto tik rugpj\u016bt\u012f. Tai i\u0161 ties\u0173 kelia nerim\u0105\u201c, \u2013 sak\u0117 Ciuricho ETH glaciologas Matthias Huss.<\/p>\n
Ekspert\u0173 vertinimu, \u0161\u012f sezon\u0105 ledynai \u012f \u0161iltesn\u012f laikotarp\u012f \u012f\u017eeng\u0117 su ma\u017eesniu sniego kiekiu nei daugiametis vidurkis, o v\u0117liau sekusios kar\u0161\u010dio bangos proces\u0105 dar paspartino. D\u0117l to kai kurie rodikliai, pasak steb\u0117sen\u0105 vykdan\u010di\u0173 specialist\u0173, pasiek\u0117 v\u0117lyvai vasarai b\u016bding\u0105 lyg\u012f ma\u017edaug m\u0117nesiu anks\u010diau.<\/p>\n
Tokie poky\u010diai svarb\u016bs ne tik kaln\u0173 regionams. Ilgainiui tai gali reik\u0161ti ma\u017eiau stabilias g\u0117lo vandens atsargas: pavasar\u012f ir vasaros prad\u017eioje vandens gali laikinai padaug\u0117ti d\u0117l spartaus tirpsmo, ta\u010diau v\u0117liau, ma\u017e\u0117jant ledo t\u016briui, did\u0117ja sausros ir \u017eem\u0173 upi\u0173 debit\u0173 rizika.<\/p>\n
Mokslininkai pabr\u0117\u017eia, kad spart\u0117jantis ledyn\u0173 tirpsmas siejamas su klimato \u0161ilt\u0117jimu, o ekstremalios kar\u0161\u010dio bangos Europoje tampa da\u017enesn\u0117s ir intensyvesn\u0117s. Praktikoje tai rei\u0161kia, kad ledyn\u0173 steb\u0117sen\u0105 tenka vykdyti vis da\u017eniau: nuo palydovini\u0173 vaizd\u0173 iki vietoje atliekam\u0173 matavim\u0173, kurie leid\u017eia tiksliai fiksuoti, kaip greitai ma\u017e\u0117ja ledo sluoksnis.<\/p>\n
\u201eTai n\u0117ra istorija apie tai, kas nutiks po \u0161imto met\u0173. Kai kuriuos padarinius galime pajusti per artimiausius 10\u201320 met\u0173\u201c, \u2013 pabr\u0117\u017e\u0117 Matthias Huss.<\/p>\n","protected":false},"excerpt":{"rendered":"
