Sicela uthole ukuthi yini ebangela ukuguquka kwesimo sezulu
Context:Ngokuvamile, ukuguquka kwesimo sezulu kuchaza ukufudumala kwembulunga yonke - ukwanda okuqhubekayo kokushisa okuphakathi komhlaba - nemiphumela yako esimisweni sezulu somhlaba. Ukushintsha kwesimo sezulu ngomqondo obanzi kuhlanganisa nezinguquko zesikhathi eside zesimo sezulu somhlaba. Ukwanda kwamanje kwezinga lokushisa embulungeni yonke kuyashesha kunezinguquko zangaphambili, futhi kubangelwa ngokuyinhloko abantu abashisa izinto zokubasa ezimbiwa phansi. Ukusetshenziswa kukaphethiloli, ukugawulwa kwamahlathi, nemikhuba ethile yezolimo nezezimboni kwandisa amagesi abamba ukushisa, ikakhulukazi i-carbon dioxide ne-methane. Amagesi abamba ukushisa amunca okunye kokushisa okuvezwa uMhlaba ngemva kokuba usufudumele ngenxa yelanga. Amanani amakhulu ala magesi abamba ukushisa okwengeziwe emkhathini ophansi woMhlaba, abangele ukufudumala kwembulunga yonke.  Ngenxa yokuguquka kwesimo sezulu, izingwadule ziyanda, kuyilapho amagagasi okushisa nemililo eqhubekela phambili. Ukwanda kokushisa e-Arctic kuye kwabangela ukuncibilika kweqhwa elihlala likhona, ukuhlehla kwezinguzunga zeqhwa nokulahleka kweqhwa lolwandle. Amazinga okushisa aphakeme futhi abangela iziphepho ezinamandla, isomiso nezinye izimo zezulu ezimbi kakhulu. Ukushintsha okusheshayo kwemvelo ezintabeni, ezixhotsheni zamakhorali nasezindaweni ezibandayo kuyiphoqa izinhlobo eziningi zezinto eziphilayo ukuba zithuthele kwenye indawo noma ziqothulwe. Ngisho noma imizamo yokunciphisa ukufudumala kwembulunga esikhathini esizayo iphumelela, eminye imiphumela iyoqhubeka amakhulu eminyaka. Lezi zihlanganisa ukufudumala kwezilwandle, ukwanda kwe-acidification yolwandle nokwenyuka kwezinga lolwandle.
1. Izinkomo Ukuguquka kwesimo sezulu kubangelwa ngokuyinhloko abantu abashisa izinto zokubasa ezimbiwa phansi. 2. Izingelosi ukusetshenziswa kukaphethiloli, 3. ukugawulwa kwamahlathi, 4.izindlela zokulima nezimboni ziyanda
