Isitatimende se-Ocean Foundation kumbiko we-IPCC wesi-6

The 6^th Umbiko we-IPCC yadedelwa ngomdlandla othile ngo-Agasti 6th - iqinisekisa esikwaziyo (ukuthi eminye yemiphumela yokukhishwa kwesisi esibamba ukushisa ngokweqile ayinakugwenywa okwamanje), kodwa nokho inikeza ithemba elithile uma sizimisele ukwenza okuthile endaweni, esifundeni nasemhlabeni jikelele. Lo mbiko uqinisa imiphumela ososayensi abebeyibikezela okungenani kule minyaka eyishumi nengxenye edlule.   

Sesivele sibona izinguquko ezisheshayo ekujuleni kolwandle, izinga lokushisa kanye namakhemikhali, kanye nesimo sezulu esibi kakhulu emhlabeni jikelele. Futhi, singaqiniseka ukuthi olunye ushintsho lungenzeka—ngisho noma singakwazi ukukala imiphumela. 

Ngokukhethekile, ulwandle luya lufudumala, futhi izinga lolwandle lomhlaba wonke liyakhuphuka.

Lezi zinguquko, ezinye zazo ezizolimaza kakhulu, azinakugwenywa. Izehlakalo zokushisa okwedlulele zingabulala izixhobo zamakhorali, izinyoni zasolwandle ezifudukayo kanye nempilo yasolwandle—njengoba inyakatho-ntshonalanga ye-United States yafunda izindleko zayo kuleli hlobo. Ngeshwa, izehlakalo ezinjalo ziphindaphindeke kabili kusukela ngawo-1980.  

Ngokombiko, kungakhathaliseki ukuthi senzani, izinga lolwandle lizoqhubeka nokukhuphuka. Kule minyaka eyikhulu edlule, amazinga olwandle anyuke ngesilinganiso esingama-intshi angu-8 futhi izinga lokukhula liphindeke kabili kusukela ngo-2006. Emhlabeni wonke, imiphakathi ibhekene nezikhukhula eziningi futhi ngaleyo ndlela ukuguguleka nokulimala kwengqalasizinda. Futhi, njengoba ulwandle luqhubeka lufudumala, amaqhwa e-Antarctica naseGreenland angase ancibilike ngokushesha kunalokho avele eyikho. Ukuwa kwabo kungaba nomthelela cishe izinyawo ezintathu ezengeziwe ekukhuphukeni kwezinga lolwandle.

Njengozakwethu, angimangazi ngalo mbiko, noma indima yethu yomuntu ekubangeleni inhlekelele yesimo sezulu. Umphakathi wethu ukubonile lokhu kuza isikhathi eside. Ngokusekelwe olwazini oseluvele lukhona, Ngixwayise ngokuwa "yebhande le-Gulf Stream" lase-Atlantic Ocean, embikweni ka-2004 wozakwethu. Njengoba iplanethi iqhubeka nokufudumala, amazinga okushisa olwandle afudumalayo anciphisa le misinga ebalulekile yolwandle i-Atlantic esiza ukusimamisa isimo sezulu eYurophu, futhi aya ngokuya ebhidlika kungazelelwe. Ukuwa okunjalo kungase kuphuce iYurophu ukufudumala okulinganiselwe kolwandle.

Noma kunjalo, ngithuswa umbiko wakamuva we-IPCC, ngoba uqinisekisa ukuthi sibona imiphumela eshesha kakhulu futhi eyeqisayo kunalokho ebesikulindele.  

Izindaba ezinhle ukuthi siyazi ukuthi yini okufanele siyenze, futhi kusenewindi elifushane lokuvimba izinto zingabi zimbi nakakhulu. Singanciphisa ukukhishwa kwekhabhoni, siye emithonjeni yamandla e-zero-carbon, ukuvala izikhungo zamandla angcolisa kakhulu, bese uphishekela ukubuyiselwa kwekhabhoni eluhlaza okwesibhakabhaka ukususa ikhabhoni emkhathini bese uyihambisa ku-biosphere - isu lokungazisoli net-zero.

Ngakho ungenzani?

Sekela imizamo yokwenza izinguquko ezingeni lenqubomgomo kazwelonke neyamazwe ngamazwe. Isibonelo, ugesi unegalelo elikhulu kunawo wonke emhlabeni ekukhiqizweni kwesisi esingcolisa umoya, futhi ucwaningo lwakamuva lukhombisa ukuthi yidlanzana lezinkampani ezibhekene nokukhipha intuthu eningi e-US Emhlabeni jikelele, ama-5% nje kuphela ezindawo zokuphehla amandla ezinto ezimbiwa phansi zikhipha ngaphezu kuka-70% amagesi abamba ukushisa—lokho kubonakala kuwumgomo obizayo. Thola ukuthi ugesi wakho uvelaphi bese ucela abenzi bezinqumo ukuthi babone ukuthi yini engenziwa ukuhlukanisa imithombo. Cabanga ukuthi ungawanciphisa kanjani amandla akho kanye nemizamo yokusekela ukubuyisela amasinki ethu emvelo ekhabhoni—ulwandle lungumfelandawonye wethu kulokhu.

Umbiko we-IPCC uyaqinisekisa ukuthi isikhathi manje sokunciphisa imiphumela emibi kakhulu yokushintsha kwesimo sezulu, njengoba sifunda ukuzivumelanisa nezinguquko eseziqhubeka. Isenzo esisekelwe emphakathini singaba umphumela wokuphindaphinda woshintsho lwesikali esikhulu. Sisonke kulokhu.
