Kubukeka kumangalisa, kepha a GIF ingasiqaphelisa ngosongo lwangempela olubangelwa ukufudumala kwembulunga yonke. Lo mfanekiso osuthuthukisiwe, othuthukiswe umcwaningi waseBrithani u-Ed Hawkins, ubonisa ngendlela elula kakhulu ukuthi amazinga okushisa abelokhu ekhuphuka kanjani kusukela ngo-1850, nokuthi siseduze kangakanani nokufinyelela ku-2 degrees Celsius, umkhawulo okuthi, uma weqiwe, ubangele imiphumela eyinhlekelele emhlabeni wethu.
Ukukhuphuka kwamazinga okushisa yikhona okukhathaza kakhulu, futhi ngesikhathi esifanayo, yikuphi okulula ukukubona. Ngokwezifundo ezihlukahlukene zesayensi, uma siwela umkhawulo ongu-2°C, imiphumela ngeke ibulale imvelo kuphela kodwa nasesintwini. Ngalo mqondo, kuyethusa ukuthi ukuqagela okuningi kubonisa ukuthi sinjalo kusondelene ukunqoba leso sivimbelo esibucayi.
Imininingwane mayelana ne-Ed Hawkins GIF
Hawkins, osebenza e-National Center for Atmospheric Science e-University of Reading e-United Kingdom, waqala ukubonisa izinguquko ezenzeka kakade ekushiseni kweplanethi yethu. Ukuze afeze lokhu, ukhethe idizayini entsha: i-GIF ikhombisa i-polygonal spiral lokho wethule imininingwane ngokucacile nangokuqondile kumbukeli.
Ukuphenduka ngakunye kwe-spiral imele ukwanda kwamazinga okushisa, ezilokhu zishintsha inyanga nenyanga kanye neminyaka eyishumi kuya eshumini. Lesi sithombe esibonakalayo senza umlayezo ucace ngokushesha: ukufudumala komhlaba kuyiqiniso elingephikwe elilokhu likhula kusukela ngo-1850. Ungabona i-GIF ngezansi:
Njengoba kungase kubonakale, kusukela ngo-1990 kuye kwaba nokwanda okuphawulekayo kwezinga lokushisa embulungeni yonke. Leli qiniso seliholele ekutheni lolu daba luthathelwe phezulu, njengoba amazinga okushisa eqoshwa njalo ngenyanga. Uma leli zinga liqhubeka, maningi amathuba okuthi maduze nje kunalokho esikucabangayo, izinga lokushisa elijwayelekile emhlabeni wonke lizobe selikhuphuke ngama-degree Celsius amabili asabekayo. Lokhu kunemiphumela eyahlukene, kusukela emiphumeleni elimazayo ku-ecosystem kuya kumthelela oqondile empilweni yomuntu.
Imiphumela yokushisa komhlaba
Imiphumela yokufudumala kwembulunga iyethusa futhi ihlanganisa izindawo eziningi. Eminye yemiphumela engaba khona ihlanganisa:
- Ukwehla kweqhwa: Ukwenyuka kwamazinga okushisa kubangela ukuba izinguzunga zeqhwa zinyamalale emhlabeni wonke, okunomthelela ekukhuphukeni kwamazinga olwandle.
- Imicimbi yesimo sezulu esibi kakhulu: Ukufudumala kwembulunga yonke kuhlotshaniswa nokwanda kwemvamisa nokuqina kwezimo zezulu ezimbi kakhulu, njengeziphepho, isomiso namagagasi okushisa.
- Imithelela ku-biodiversity: Izinhlobo eziningi zezilwane zisengozini yokushabalala ngenxa yoshintsho ezindaweni zazo zemvelo kanye nokulahlekelwa kwezinhlobonhlobo zezinto eziphilayo. Ungafunda kabanzi mayelana izilwane ezisengozini yokuqothulwa ukufudumala kwembulunga yonke.
- Izifo: Impilo yabantu nayo isengozini, njengoba ukuguquka kwesimo sezulu kungavuna ukusabalala kwezifo ezithwalwa yizilwane.
Ngenxa yazo zonke lezi zici, inselele iwukuqonda ukuthi ukufudumala kwembulunga yonke kubonisa usongo lwangempela okufanele kubhekwane nalo ngokushesha. Nakuba abaholi bomhlaba kuyibo abanamandla okusebenzisa izinqubomgomo eziphumelelayo zokudambisa inkinga, izakhamuzi ezivamile zingakwazi futhi kufanele zenze ingxenye yazo. Ezinye izenzo esingazithatha zihlanganisa Phinda usebenzise kabusha, sebenzisa futhi, ungangcolisi, futhi londoloza amanzi. Konke okuncane kuyasiza futhi kungaba nomthelela ekwenzeni ngcono isimo seplanethi yethu.
Ngaphezu kwalokho, kubalulekile ukuqaphela ukuthi isivumelwano esafinyelelwa eNgqungqutheleni Yamazwe YaseParis (COP21) ngoZibandlela wezi-2015, esihlose ukugcina ukufudumala kwembulunga yonke kungaphansi kuka-2°C, siyisinyathelo esibalulekile. Lesi sivumelwano sibandakanya amazwe ayi-195 futhi sigcizelela ukubaluleka kokubambisana kwamazwe ngamazwe ekulweni nokuguquguquka kwesimo sezulu.
Ukubona ngeso lengqondo kuka-Hawkins kubambe iqhaza elibalulekile ekuqwashiseni lolu daba nasekukhuthazeni izingxoxo ezifinyelelekayo mayelana nemithelela yayo. Ngakho-ke, izinyathelo ezinjengalezi zibalulekile ekuqondeni ubucayi besimo kanye nokuhlanganisa imizamo yomhlaba wonke yokuhlehlisa imiphumela yokufudumala kwembulunga yonke. Ulwazi olubonakalayo alufinyeleleki kuphela, kodwa futhi lungaba namandla ekukhuthazeni izenzo ezihlangene.
Ukuxhumana okuphumelelayo nomsebenzi wokubambisana kubalulekile uma sifuna ukuhlehlisa inkambo yokufudumala kwembulunga yonke futhi siqinisekise ikusasa elisimeme lezizukulwane ezizayo. Ngokubambisana, singenza umehluko.
