<prompt> Fingqa isihloko: I-Gulf Stream, umfutho wamanzi olwandle oletha isimo sezulu esipholile enyakatho Yurophu nesimo sezulu esipholile eningizimu-mpumalanga ye-U.S., uncipha ngesivinini esisheshayo eminyakeni eyi-1.000. Ucwaningo olusha luveze ukuthi imisinga emikhulu ehambisa amanzi afudumele nabandayo azungeze ulwandle i-Atlantic iye yehla ngamaphesenti angu-15 kuya kwangu-20 phakathi nekhulu leminyaka elidlule. Ososayensi bathi ukugeleza kwamanzi ahlanzekile okwandayo okuvela ekuncibilikeni kwezingqimba zeqhwa laseGreenland kungase kube okubangela ukunciphisa ijubane. Isithombe esingenhla sibonisa ukuthi ulwandle olusenyakatho ye - Atlantic lupholile kunolwandle oluzungezile ngenxa yokungena kwamanzi ahlanzekile ngenxa yokuncibilika kweqhwa laseGreenland, okuye kwehlisa ijubane leGulf Stream, kusho ososayensi. UProfesa Stefan Rahmstorf, isazi sesayensi yezilwandle ePotsdam Institute for Climate Impact Research, wathi: Kuyaphawuleka ukuthi enye indawo ethile eNyakatho ye-Atlantic iye yaphola eminyakeni eyikhulu edlule kuyilapho umhlaba wonke ushisa. Manje sesithole ubufakazi obunamandla bokuthi empeleni i-conveyor yomhlaba wonke iye yaba buthakathaka eminyakeni eyikhulu edlule, ikakhulukazi kusukela ngo-1970. Ukuguquka kwesimo sezulu kungenza ukudla esikudlayo kunambitheke kabi, ngokusho kocwaningo lwakamuva. Umbiko omkhulu ngomphumela wokufudumala kwembulunga ekudleni uye wabikezela ukuthi izinga lenyama nemifino eminingi liyokwehla njengoba amazinga okushisa enyuka. Abacwaningi babikezela ukuthi njengoba amagagasi okushisa eba avamile, inyama enjengenkukhu nenyama yenkomo iyoqina futhi iqine ngokwengeziwe. Izaqathe cishe ziyolahlekelwa ukunambitheka kwazo futhi zibe nokuthungwa okungajabulisi kangako. Ama-beet no-anyanisi kuyoba mancane kuyilapho ubisi luyoba namaprotheni amancane adingekayo ukuze kwenziwe ushizi. Ucwaningo oluhlukile olwenziwa izazi zezinto eziphilayo zasolwandle luye lwabonisa nokuthi izimfanzi ziyoba nokunambitheka okumuncu njengoba ulwandle lwethu luba ne-asidi. Baxwayisa ngokuthi njengoba ulwandle lomhlaba luba ne-asidi, ngenxa yokwanda kwamazinga e-carbon dioxide, ukudla kwasolwandle esikuthandayo kungase kungabi mnandi kangako. Izinhlanzi ezikhuliswe emanzini anenani le-pH eliphansi zazinamathuba aphindwe izikhathi ezingu-2,6 okubhekwa njengokunambitheka okubi kakhulu, kuyilapho lezo ezikhuliswe emanzini ane-asidi encane zazinalo...  <response>: Ososayensi basePotsdam Institute for Climate Impact Research bathole ukuthi ulwandle olusenyakatho ye-Atlantic ocean lubanda kakhulu kunalokho okubikezelwa amamodeli ekhompyutha. Bathi imisinga yasolwandle eqhuba iGulf Stream iye yehla ngo - 15-20. Abacwaningi bathi amanzi ahlanzekile avela ezingqwembeni zeqhwa ezincibilikayo angaba yimbangela yalokhu. Bathi ukugeleza kwamanzi ancibilikile sekusheshise muva nje ngenxa yokushintsha kwesimo sezulu. Ukwehla kweGulf Stream kungase kusho ubusika obunzima kakhulu enyakatho Yurophu. Amazinga okushisa kwamanzi azungeze iFlorida kanye nogu olusempumalanga ye-US nawo angathinteka.
