Ingxelo ye-Ocean Foundation kwiNgxelo ye-IPCC yesi-6

The 6^th Ingxelo ye-IPCC yakhululwa nge-fanfare ngo-Agasti we-6th - iqinisekisa into esiyaziyo (ukuba ezinye zeziphumo zokukhutshwa kwegesi ye-greenhouse engaphezulu ayinakuphepheka okwangoku), kwaye sekunjalo inika ithemba elithile ukuba sizimisele ukwenza okuthile ekuhlaleni, kwingingqi nakwihlabathi jikelele. Ingxelo iqinisekisa iziphumo ezixelwe kwangaphambili zizazinzulu malunga neshumi elinesiqingatha leminyaka edlulileyo.   

Sele sibona utshintsho olukhawulezayo kubunzulu bolwandle, ubushushu kunye nekhemistri, kunye nemozulu eyongezelelekileyo kwihlabathi jikelele. Kwaye, sinokuqiniseka ukuba utshintsho olungakumbi lunokwenzeka-nokuba asikwazi ukulinganisa iziphumo. 

Ngokukodwa, ulwandle luya lufudumala, kwaye inqanaba lolwandle lwehlabathi liyenyuka.

Ezi nguqu, ezinye zazo eziya kuba yingozi, ngoku azinakuphepheka. Iziganeko zobushushu obugqithisileyo zinokubulala iingqaqa zekorale, iintaka zaselwandle ezifudukayo kunye nobomi baselwandle—njengoko umntla-ntshona weUnited States wafunda kwiindleko zawo kweli hlobo. Ngelishwa, iziganeko ezinjalo ziye zaphindaphindeka kabini ukususela ngo-1980.  

Ngokwengxelo, nokuba senza ntoni na, umgangatho wolwandle uya kuqhubeka unyuka. Kwinkulungwane edlulileyo, amaqondo olwandle anyuke ngomyinge ozii-intshi ezisi-8 kwaye izinga lokunyuka liphindeke kabini ukusukela ngo-2006. Kwihlabathi liphela, uluntu lufumana izehlo zezikhukula kwaye ngoko ke ukhukuliseko nokwenzakala okukhulu kwiziseko ezingundoqo. Kwakhona, njengoko ulwandle luqhubeka lufudumala, imikhenkce e-Antarctica naseGreenland isenokwenzeka ukuba inyibilike ngokukhawuleza kunokuba sele injalo. Ukuwa kwabo kunokuba negalelo malunga noku iinyawo ezintathu ezongezelelweyo ukunyuka komphakamo wolwandle.

Njengoogxa bam, andothuswa yile ngxelo, okanye nendima yethu yomntu ekudaleni intlekele yemozulu. Uluntu lwethu luyibonile le nto ixesha elide. Ngokusekelwe kulwazi olwalusele lukhona, Ndalumkisa ngokuwa ye-Atlantic Ocean's Gulf Stream "ibhanti lokuhambisa," kwingxelo ka-2004 yabalingane bam. Njengoko iplanethi iqhubeka nokufudumala, ukufudumala kwamaqondo obushushu olwandle kuyacothisa le misinga ibalulekileyo yolwandlekazi lweAtlantiki enceda ukuzinzisa imozulu yaseYurophu, kwaye iya isiba lula ukuwohloka ngequbuliso. Ukuwohloka okunjalo kunokuba ngequbuliso kuhluthe iYurophu ubushushu obuphakathi kolwandle.

Nangona kunjalo, ndothuswa yingxelo yamva nje ye-IPCC, kuba iqinisekisa ukuba sibona iziphumo ezikhawulezayo nezigqithileyo kunokuba besinethemba.  

Iindaba ezimnandi kukuba siyayazi into ekufuneka siyenzile, kwaye kusekho ifestile emfutshane yokunqanda izinto ukuba zingabi mbi ngakumbi. Singakwazi ukunciphisa ukukhutshwa, ukuya kwimithombo yamandla e-zero-carbon, ukuvala awona mandla angcolisekileyo, kwaye ulandele ukubuyiselwa kwekhabhoni eluhlaza okwesibhakabhaka ukususa ikhabhoni kwi-atmosfera kwaye uyihambise kwi-biosphere - isicwangciso sokungazisoli se-net-zero.

Ke unokwenza ntoni?

Ukuxhasa iinzame zokwenza utshintsho kwinqanaba lomgaqo-nkqubo wesizwe kunye namazwe ngamazwe. Umzekelo, umbane lolona galelo likhulu kwihlabathi ekukhutshweni kwegesi yendalo, kwaye uphando lwakutsha nje lubonisa ukuba liqaqobana nje leenkampani ezinoxanduva lokukhutshwa kwezinto ezininzi e-US Kwihlabathi jikelele, yi-5% nje kuphela yezityalo zamandla efosili zikhupha ngaphezulu kwe-70% iigesi ze-greenhouse-ebonakala ngathi yinjongo engabizi kakhulu. Fumanisa apho umbane wakho uvela khona kwaye ucele abenzi bezigqibo ukuba babone into enokwenziwa ukudibanisa imithombo yolwazi. Cinga ngendlela onokuthi unciphise ngayo amandla akho kunye nemigudu yenkxaso yokubuyisela i-carbon sinks yethu yendalo-ulwandle luyiqabane lethu kulo mba.

Ingxelo ye-IPCC iyangqina ukuba ngoku lixesha lokunciphisa ezona ziphumo zinzima zokutshintsha kwemozulu, njengoko sifunda ukuziqhelanisa notshintsho olusele luqhubeka. Isenzo esisekwe eluntwini sinokuba sisiphumo sokuphindaphinda kutshintsho lwesikali esikhulu. Sisonke sikunye kule nto.
