Uzothini ukuncibilika okwengeziwe kwezinguzunga zeqhwa okwakungokokuqala ngqá e Greenland?

Ngokudabukisayo, usenesikhathi ukusayinwa Kyoto sivumelwano isimo sezulu eplanethini yethu kunzima. Ngaphezu kwalokho, phakathi neminyaka eyikhulu nengxenye-esidlule ke iye yaqhubeka iwohloka kakhulu kusukela ngesilinganiso ice ukuncibilika e Greenland kanye Antarctica is kakhulu kuye embili ngesivinini.

Okukhathaza nakakhulu lososayensi iyancibilika zeqhwa eGreenland, ukuthandwa lapho iplanethi ingakamiswa eqoshiwe. Ochwepheshe ukubika ukuthi sizokwazi ngokufanele ngokuthi "isiqhingi oluhlaza" ngenxa ice kuso angahlali engu-30 edlule observation, izinga leqhwa ukuncibilika liye landa kakhulu ukuthi eminyakeni embalwa, Greenland.

Ukukhathazeka Kuyaphawuleka ukuthi ngisho ngesikhathi amaphuzu eliphakeme yalesi siqhingi emangalisayo, lapho iqhwa akazange ancibilike zeminyaka, njengoba ukuncibilika kwezinguzunga zeqhwa okwakungokokuqala ngqá umiselwe. Kubikwa ukuthi uma iphesenti ngaphambilini ancibilike Kwakungekhona ngaphezu-40%, kodwa manje liye landa laba ngu-97%. Into embi kakhulu wukuthi ososayensi nje abakwazi ukuchaza uhlobo lesi simanga.

Eziningana uthulisa yokuthi ice ngokwengxenye abuyiselwe, kodwa lokhu akwenzeki ngokushesha lokho kwaba ngaphambi. Cishe nsuku zonke Greenland ice ishidi iyehlukana kude izingcezu bayanda ice, usayizi okuyinto ezimweni eziningi kukhona omkhulu. Endaweni eyodwa yalezi zeqhwa ukuthi manje egcinwe ku ukukhukhuleka eduze lwaseCanada idlule sq 200. km!

Indlela lisongela iplanethi yethu? Into embi kakhulu wukuthi zamaqhwa ukuncibilika 2012 singabangela kuyanda ezadala umonakalo ngo ezingeni Umhlaba Ocean. Ososayensi babikezela ukuthi ngemva ukuncibilika ephelele ice Greenland zingakhula yena amamitha 6 nje. Kufanele kuqondwe ukuthi ukuvusa ezingeni imitha kuphela igcwele izinhlekelele ngendlela engakholeki. Uma ukuncibilika kwezinguzunga zeqhwa okwakungokokuqala ngqá uzoqhubeka ngezinga elifanayo, bese sonke isintu kuyodingeka nezikhathi ezinzima.

ososayensi Ikakhulukazi engenathemba ukubikezela kungenzeka ngokuzumayo displacement zomhlaba amapuleti ngenxa ukukhululwa kwabo okusheshayo kusuka ngaphansi mass Amazing okuyinto ziqhubeka kubo eyodwa yeminyaka. Uma lezi emisebenzi zigcwaliseka ke ukuncibilika kwezinguzunga zeqhwa zingase avuse okuvela yesibili "indandatho lomlilo" izintaba-mlilo emhlabeni. Ngalesi sikhathi izikhungo kuqhuma ngeke ibe ophephile ukuba elwandle eliKhulu iPacific, futhi ngasogwini Europe nje.

Kungenzeka yini ukuvimbela yemiphumela enjalo edabukisayo? Ngeshwa, ngokwengxenye kuphela. Misa inqubo egijima ukunyamalala ice emhlabeni ngokuphelele, ngeke sikwazi. Kunoma ikuphi, ezingeni samanje yentuthuko kwezobuchwepheshe. Ngaphezu kwalokho, asikwazi ngokuqiniseka yini edale ngesilinganiso ezinjalo ukunyamalala ice izinto ezenziwa abantu noma ezinye, asiyazi izizathu.

Asikwazi ukuqapha ngokucophelela kuphela ukuncibilika kwezinguzunga zeqhwa futhi ifike ngesikhathi ukuthatha izinyathelo ukuze kuphunywe abantu nasemizaneni eziyingozi kakhulu ugu nemizana. Linendima ebalulekile kanye nomsebenzi okuqhubekayo izazi zokuzamazama komhlaba, okungase ukuqinisekisa noma ukuphikisa imfundiso yokuziphendukela ukuguquguquka izingqimba zomhlaba.
