Amaza obushushu aya esonyuka kwaye esiya rhoqo kwiindawo ezininzi zehlabathi, kodwa kwezo sele zikhona, ubuncinci iinyanga ezimbalwa ngonyaka, ziya kubangela iingxaki ezininzi kwixa elizayo. Kwaye inyani kukuba ngolwandle olufudumeleyo, kuya kusiba nzima ngakumbi ukufumana iintlanzi ezikhoyo njengoko inani labo liza kuncipha, into eyenzekileyo kuLwandle lwaseTasman.
Ngexesha lokugqibela lasehlotyeni, amaza obushushu angahlali ngaphezulu okanye ngaphantsi kweentsuku ezingama-251, anyusa ubushushu bamanzi phantse ngeedigri ezintathu, ngokukodwa, 2,9 ° C. Olu konyuka lubangele ukwehla kwemveliso yeefama ze salmon, kunye nokonyuka kweembatyisi kunye nokufa kweabalone. Njengokuba oku kwakungonelanga, kukhokelele ekufikeni kweentlobo ezininzi zangaphandle, ngokophando olukhokelwe sisazinzulu u-Eric Oliver
Ukufudumala koLwandle lwaseTasman kweli hlobo lasehlotyeni elisemazantsi yeyona nto yayixhalabisa kuba kukho iirekhodi: ichaphazele indawo yolwandle ephindwe kasixhenxe kunesiqithi, kunye namaxabiso ukuya kuthi ga kwi-2,9 degrees Celsius ephezulu kunesiqhelo, utshintsho lwemozulu ngokuqinisekileyo luxanduva.
UOliver uthe ukukhululwa »Sinokuqiniseka nge-99% ukuba utshintsho lwemozulu ye-anthropogenic lwenze ukuba ubushushu baselwandle butshudise amaxesha amaninzi, kwaye yonyusa amathuba okuba ezi ziganeko zigqithisileyo ziphindaphindwe kwixesha elizayo.
Uphononongo, olushicilelwe kwijenali Nature Communications, egxile kummandla wonxweme olusempuma yeTasmania. Ubushushu obushushu kubangelwe sisikhukula samanzi ashushu avela kwimpuma ye-Australia, ethe kumashumi eminyaka akutshanje ibisomeleza kwaye isanda ukuya emazantsi.
Yiyo loo nto, ukuba kuthathwa amanyathelo okuthintela ukutshintsha kwemozulu, amanzi aya kuqhubeka eshushu ngakumbi.
