Iindaba zamva nje, ukwenzela ukunciphisa ukuhamba kwe-atlantic yomjelo wegalufa okanye i-iceberg, ubungakanani be-St. Ngendlela efanayo nemililo yehlathi enomlilo wePlanethi yethu ngo-2020, i-gollstrum kunye nokunyibilika kwe-arctic grecier kusenokwenzeka ukuba sisiphumo sokutshintsha kwemozulu. Ukufudumeza ngoku, ngaphandle kwento yokuba ubushushu kwiplanethi kukutshintsha ngokuphindaphindiweyo kuyo yonke imbali yayo, ebangelwa yimisebenzi ye-anthropogenic, njengoko kungqinwe ziziphumo zophando lwezenzululwazi. Ngenxa yokuba ukwanda kwenani leziganeko zemozulu ezigqithileyo kuqikelelwa ziimodeli ezininzi zemozulu, izazinzulu kunye neenkokheli zehlabathi kufuneka zenziwe izinto ezifanelekileyo kumlo wokulwa neziphumo zotshintsho lwemozulu. Kungenxa yoko le qela labaphandi bamanye amazwe lineenzame ezidibeneyo zokudala "i-gagin yedijithali". Imodeli iya kubonelela ngenkqubo yolwazi yemeko yovavanyo ngeendlela ngeendlela ngeendlela zophuhliso oluzinzileyo.
Kutheni le iplanethi yethu iwele?
Ifuthe lomsebenzi woluntu ekugxinisweni kwegesi eluhlaza okwesibhakabhaka kwimozulu, kunye nefuthe kwinkqubo yemozulukile yabhalwa yaza yabhalwa linani elikhulu leempapasho. Ukuqukumbela ukuba ukukhutshwa kwe-anthropogengegengegegege Greenhouse Gases kufuneka kunciphile kakhulu kumashumi amahlanu eminyaka-ukunqanda intlekele yemozulu- namhlanje sisivumelwano senzululwazi.
Ngokwengxelo yeZizwe eziManyeneyo (i-UN), kule minyaka ingama-20 idlulileyo, i-phenomena yemozulu egqithileyo iyenzeka rhoqo. Ukususela ngo-2000 ukuya ku-2019, ii-1.23 ezigidi zabantu bafa ngenxa yentlekele enkulu engama-7348. Kwiminyaka engamashumi amabini ngaphambi kokuba uthelekise iintlekele zemvelo ezi-1.12 zemvelo. Iimeko zemozulu ezigqithisileyo ze-2,97 iidola ze-proos ze-jippers ze-rhulumente ezidlulileyo xa kuthelekiswa ne-1.63 yeedola kwishumi amabini ngaphambili.
La manani kulindeleke ukuba akhule, akhuthaze abaphandi ukuba baphuhlise izigqibo zezopolitiko ezinkulu kumazwe ahlukeneyo. Njengenxalenye yesicwangciso sokunciphisa ukukhutshwa kwemozulu ngo-2050, i-European Union yaqalisa inyathelo lokuqala lomhlaba. Ngoncedo lwayo, izazinzulu "zilandelela kwaye zicwangcise imicimbi yemozulu yexesha elizayo kunye nokuphendula kubo," utshilo kwingxelo yakutshanje.
Ufuna ukuhlala usazi ukufunyanwa kwesayensi kasayensi kwicandelo le-cosmology, i-physics kunye ne-Astrolonom, bhalisela isitishi semihla yethu kwi-telegraph, ukuze ingaphoswa nantoni na enomdla!
Abaphandi abavela kwiziko laseYurophu kwimigangatho yemozulu ephakathi (i-ECMWF), i-Arhente yendawo yaseYurophu (i-ESA) kunye noMbutho waseYurophu yeSteorologima yeMeteorological Satellites (i-Eumetst) nayo iyasebenzisana ekukhuthazeni iprojekthi entsha. Inkqubo kunye neekhilimo zenza zonke iinzame zokwenza amawele edijithali yomhlaba.
Qaphela ukuba le ayisiyonto inomdla kakhulu, kodwa neprojekthi yamabhongo kakhulu enzululwazi abafuna ukufezekisa iziphumo kule minyaka ilishumi izayo. Kungathiwa, le modeli ineenkcukacha ezimbini zomhlaba iphuhliswa ukuze ubone ukuba ngaba ukuba ngaba izinto ezenziwayo ziya kuphumelela xa kulwa utshintsho lwemozulu ngaphambi kokuba alisebenzise kwihlabathi lokwenyani. Imodeli enjalo njengesiphumo iya kunceda wonke umntu ukuba aziqonde ngakumbi iingxaki kwaye alungise iimpazamo ezinokwenzeka, kwaye kwangaxeshanye enze isicwangciso esicacileyo sezenzo ezilandelelanayo kunye neziphumo zazo.
Yifunde: Ihlabathi Liza kuba Ntoni Ihlabathi engama-2050, ukuba awuyeki ukutshintsha kwemozulu?
Ukudalwa kwekopi echanileyo yomhlaba kuya kugcina kakhulu iindleko zeeprojekthi ezinemisebenzi ekuza kuba kukungasebenzi. Isicwangciso sokunciphisa ukutshintsha kwemozulu, sivavanywe kwaye sibonwe 'kumhlaba ophindiweyo' siza kusindisa ixesha elininzi, amandla kunye nezixhobo.
Ngokwendlela ye-Zurich, iikhompyuter zanamhlanje ezisebenza kakhulu ezisebenza kwi-algorithms ezintsonkothileyo ziyakwazi ukusebenzisa kunye nokulungisa iivolumu zedatha enkulu. Abasebenzi kunye nabaphuhlisi beprojekthi ye-diphhung shinen kufuneka benze ii-algorithms eziyimfuneko kwaye basebenzise ezona zinto zilungileyo zehlabathi ukuze asebenzise amawele. Ngokwezicwangciso zezazinzulu, le nkqubo iya kuthatha iminyaka elishumi.
Kunomdla: Ikamva lehlabathi lonke loluntu kulapho sihamba khona?
Ngo-2025, iqela liceba ukuqalisa kwamawele amahlanu edijithali. Emva koko idatha yale fowuni iya kudityaniswa ukuze kudaleke i "Dial yedijithali yomhlaba". Abaphandi baqaphele ukuba i-Supercomputer yexesha elizayo kufuneka yakhiwe apho, apho iindawo zayo ziya kukwazi ukusebenza kwimithombo yamandla ahlaziyiweyo, ngenye indlela iya kuvelisa inani elikhulu le-CO2. Ewe, siya kulinda iindaba ezilungileyo!
