Phakathi kwezingoma ze-"Five Years", uDavid Bowie wacula "umfana wezindaba wakhala wasitshela ukuthi Umhlaba uyafa". Ezinsukwini eziyi-18,250 kamuva noma okufana neminyaka engamashumi amahlanu, isigamu sekhulu noma, nje, iminyaka engu-50, umlayezo uyafana "sisesinqumweni esiwujuqu", kuxwayisa u-Alicia Pérez-Porro, isazi sezinto eziphilayo zasolwandle kanye nomxhumanisi wesayensi wamanje wocwaningo. Centre Ecology and Forestry Applications (CREAF).
Isexwayiso esisodwa sethulwa ngoJuni 1972 eNgqungqutheleni yokuqala yeZizwe Ezihlangene mayelana nemvelo yabantu. “Sifinyelele isikhashana emlandweni lapho kufanele siqondise izenzo zethu emhlabeni wonke sinaka kakhulu imiphumela ezingaba nayo ngendawo ezungezile,” kusho imibhalo yalowo mhlangano.
“Ngo-1972 kwaba sobala ngokuphelele ukuthi kunesimo sezulu nokuthi isimo sendawo ezungezile sasibangela amahloni,” kukhumbula uJoaquín Araújo, isazi semvelo. Isimemezelo esalandela sacaciswa ezimisweni zaso: “Ngokungazi noma ngokunganaki singabangela umonakalo omkhulu futhi ongenakulungiseka endaweni ezungezile ewumhlaba lapho ukuphila kwethu nenhlalakahle yethu kuncike khona.”
“Ngo-1972 kwaba sobala ukuthi isimo sezulu nesimo semvelo sasibangela amahloni” uJoaquín Araújo, isazi semvelo.
Nokho, naphezu kwezixwayiso, kuncane okushintshile. Ngokokwaziswa okuvela kuyi-IPCC, ithimba leZizwe Ezihlangene lochwepheshe ngokushintsha kwesimo sezulu, “izinga lokushisa lembulunga yonke lendawo liye lenyuka ngokushesha kusukela ngo-1970 kunanoma iyiphi enye inkathi yeminyaka engu-50 okungenani eminyakeni eyizinkulungwane ezimbili edlule.” Ngokunjalo, ukukhiqizwa kwamapulasitiki kunyuke ngo-660%, okukhomba izinhlobo zenhlangano yezemvelo.
"Ngifuna ukuba nethemba futhi yebo, izinto ezithile zenziwe kahle," kusho uPérez-Porro. "Eminyakeni yakamuva kanye nalolu bhubhane, isayensi iye yaziswa kakhulu," kuphendula isazi sezinto eziphilayo zasolwandle. “Kuyiqiniso ukuthi manje kunokuqwashisa okwengeziwe ngemvelo,” kunezela u-Araújo.
Kuyiqiniso ukuthi emashumini eminyaka angu-5 kamuva, enye yezinhloso ze-Stockholm ifinyelelwe: indawo ezungezile iphakathi nendawo yenkulumo-mpikiswano. I-IPCC ibika ukuthi “igxumele kwabezindaba,” kusho uPérez-Porro, futhi “kuyimpumelelo ukuthi minyaka yonke wonke amazwe eZizwe Ezihlangene ahlangane ukuze akhulume ngesimo sezulu,” uyanezela. Kodwa “ohulumeni bayaqhubeka nokwenqaba ukubambisana nokulahla izinto zokubasa ezimbiwa phansi,” kusho u-Alex Rafalowicz, umqondisi weFossil Fuel Non-Proliferation Treaty Initiative.

INgqungquthela yaseStockholm, ngemva kwamasonto amabili ezingxoxo, yaphetha ngeziphakamiso ezingu-26 zokuthi kuthathwe izinyathelo ezibeka izinkinga zezemvelo phambili ezinkingeni zamazwe ngamazwe. Ngemva kwalokho kwalandela Izingqungquthela Zesimo Sezulu ngawo-90. “Sibambe izingqungquthela zesimo sezulu ezingu-26 futhi sisaqhubeka nokudlala umacashelana,” kugxeka u-Araújo. "Sinesabelo esilindile esiyisenzo," kusho uPérez-Porro.

"Sisahamba kancane kakhulu ukuze sigcine iplanethi isendaweni ephephile," kweluleka uLaurence Tubiana, oyi-CEO ye-European Climate Foundation. "Okwamanje, asisahambisani Nezivumelwano Zango-2015 zaseParis," kukhumbula u-Joaquín Araújo. "Ngifuna ukucabanga ukuthi sesifikile," kubhekana no-Alicia Pérez-Porro.
Izinqubomgomo zamanje ziholela ekutheni iplanethi ibangele ukunyuka kwezinga lokushisa okungu-2,7°C ngo-2100. Umphumela omubi ezindaweni ezisemhlabeni wonke ongabangela ukushabalala kwengxenye yesithathu yezinhlobo zezitshalo nezilwane. "Nginethemba elingokoqobo futhi ngeke sifinyelele kulesi sigaba," kusho uPérez-Porro.
