Ukuqhekeka komkhenkce ongwevu njengophawu lotshintsho lwemozulu

Umkhenkce ongwevu

Utshintsho lwemozulu luyaziwa ngokwanda kwamaqondo obushushu kwihlabathi jikelele. Oku kubangela ukuba umkhenkce kunye nezibonda zinyibilike. Umzekelo ocacileyo wokuba oku kuyenzeka kukwaphuka okwenzekileyo kwi Umkhenkce ongwevu, ebekwe kwifayile ye- IPaki yeSizwe iTorres del Paine eChile.

Ukunyibilika komkhenkce kuneziphumo ezibi kumgangatho wolwandle kwaye, ke, nakwizixeko ezingaselunxwemeni. Zeziphi iziphumo ezinokubangelwa kukwaphuka komkhenkce ongwevu weGrey?

Utshintsho lwemozulu kunye nokunyibilika komkhenkce

ncibilika

Ngaphambi kokuba siqale ngomcimbi womkhenkce ongwevu weGrey, kufuneka sicacise into engeyiyo malunga nokunyibilika komkhenkce omkhenkce kunye nokunyuka kwamanqanaba olwandle. Kuyinyani ukuba oku kubangela ukunyuka kwinqanaba lolwandle, kodwa akusebenzi ngale ndlela. Kufuneka ithathelwe ingqalelo into yokuba umkhenkce ongumkhenkce odadayo elwandle, njengalawo aseMntla Pole, sele ufumene umthamo wamanzi, umkhulu nangaphezulu kunalowo uya kuwubamba ukubuyela kwimeko yolwelo. Ukunyibilika kweNtsika yoMntla ayizukubangela ukuba ulwandle lunyuke.

Kwelinye icala, ii-glaciers e-Antarctica zibekwe ngaphezulu kweshelufu yelizwekazi, ke xa zinyibilika, umthamo wamanzi aya kuba nolwandle uya kwanda.

Ukuqhekeka okungwevu kweGlacier

ukwaphuka

Kule veki kuqhekezwe ibhloko enkulu yomkhenkce eqhekeze iGlacier yeGrey. Ibhloko yomkhenkce inobukhulu obungama-350x380m kwaye, kangangeminyaka eli-12, ilahlekile ivolumu elingana ne-900 cubic metres.

Utshintsho lwemozulu yeyona ngxaki inamandla ehlabathini ejongene noluntu. Iipesenti ezingama-78 zabantu baseChile Bakholelwa ekubeni umlo ochasene notshintsho lwemozulu kufuneka ubekwe phambili kuphuhliso lwezoqoqosho lwelizwe.

Utshintsho lwemozulu luyenzeka ngoku kwaye luyenzeka apha. Yinto ecace gca le nto yabantu baseChile, ”utshilo umongameli xa evula iForam yooSodolophu malunga noTshintsho lwemozulu, eququzelelwe yi-Chilean Network of Municipalities against Climate Change kunye nombutho ongenzi nzuzo i-Adapt Chile.

Nangona abantu abaninzi bengayithathi njengeyona ibalulekileyo, kubalulekile ukuba oorhulumente basekhaya bathathe amanyathelo okunciphisa utshintsho lwemozulu ukuze, ukusuka kuluntu, ukuya kwihlabathi. Zizinto ezincinci ezikwindawo emxinwa ethe ekugqibeleni yasebenza kwihlabathi lonke.

Yintoni enokwenziwa libhunga lesixeko ngokuchasene notshintsho lwemozulu?

Umkhenkce

Umlawuli waseChile, Michelle Bachelet, isungule umsitho apho kujongwe ukwazisa ngezenzo ezinokwenziwa ngoomasipala ukunqanda ukutshintsha kwemozulu kwinqanaba lendawo. Imigaqo-nkqubo ephakanyisiweyo ngexesha lomsitho inokubekwa, iyilwe kwaye iphunyezwe koomasipala baseChile.

Esi siganeko siza kujongana nemiba ebalulekileyo echaphazela umhlaba wonke, njengokujonga Isivumelwano saseParis, Amanyathelo okuziqhelanisa notshintsho lwemozulu kunye nokuthotyelwa kweenjongo zeAgenda yokuSebenza kweMozulu.

Amaqhekeza afana nalawa eGrey Glacier aya kuba yinxalenye yesimo sokufudumala sehlabathi esingenakuphepheka nesingenakuguqulwa. Njengoko bekutshiwo ngaphambili, ezona zichaphazeleka yile meko yokunyuka komgangatho wolwandle iya kuba zizixeko ezingaselunxwemeni ngenxa yomngcipheko okhulayo wezikhukula.

Eyona mpembelelo imbi kwangoko yokuba ukwaphuka kwale glacier kunokubangela ubunzima ekuhambeni.

Kuwo onke amaqhekeza omkhenkce ehlabathi ukulinganisela okungalunganga kunokufumaneka. Koko kukuthi, Umkhenkce omninzi ulahleka ngokunyibilika kunokuba kunjalo ngokufumba kwekhephu. Lo mkhwa awuchaphazeli iGlacier yeGrey kuphela, kodwa kukho amaqhekeza omkhenkce aphulukene neshumi elinesithathu leekhilomitha kwisithuba nje esingaphaya kwamashumi amathathu eminyaka.

Le meko iya kuqhubeka minyaka le ukuba ubushushu behlabathi abupheliswa.
