Iplanethi yethu ibhekene nenani elikhulu lezimo zezulu ezimbi kakhulu. Manje ehlobo, ngokwanda kwamazinga okushisa nokuncipha kwemvula, kuqala izinkathi ezomile. Isomiso siyingozi kakhulu kubantu nasezinhlotsheni zezitshalo nezilwane. Amanzi ayafana nempilo, futhi isomiso esivame ukuvama, esishubile, nesihlala isikhathi eside sicekela phansi ibhalansi yezinto eziningi eziphilayo. Lezi zomiso anda yimiphumela ukuguquka kwesimo sezulu emhlabeni.
Ukwanda kwesomiso namazinga okushisa
Eminyakeni yamuva nje, ukuphakama okungokomlando kuye kwarekhodwa ngamapharamitha ahlukahlukene omhlaba ngenxa yezimo zezulu ezimbi kakhulu. Amazinga okushisa aphezulu, amazinga emvula amakhulu, isivinini somoya esibi kakhulu, njll. Ngokwesibonelo, Lo April wasendulo wawushisa kakhulu eminyakeni engu-137. I-National Oceanic and Atmospheric Administration (i-NOAA) yase-United States ikhombisa ukuthi ngo-Ephreli 2016 nango-2017 izinkinga ezimbili ezinkulu kakhulu zokushisa kolwandle emhlabeni jikelele zibhalisiwe kusukela ngo-1880. Lokhu kunencazelo yaso futhi kusekelwe ekwandeni kwe ukuminyana kwamagesi abamba ukushisa emkhathini. NgoJuni 14, 2017, ukuqoshwa komkhathi kwe-CO2 kwezingxenye ezingama-409,58 ngesigidi ngasinye (ppm) kwaqoshwa, isilinganiso esiqinisekisa ukuqhubeka kokwanda kwamagesi abamba ukushisa futhi okwenza kube yisiqongo esiphakeme kakhulu se-CO2 yasemkhathini etholwe eMhlabeni iminyaka engama-800.000.
Kumele kucatshangwe ukuthi ukubaluleka kokukhishwa kwegesi ebamba ukushisa ngenxa yemisebenzi yabantu kanye nomthelela wabo esimweni sezulu akunakuphikwa. Kukhona izifundo ezithi ukufudumala kwembulunga okwenziwe abantu amandla asemkhathini ayashintsha. Lokhu kubangela ukuthi imvamisa kanye namandla ezigigaba zesimo sezulu esibi kakhulu nazo zikhuphuke. Amagagasi okushisa amaningi nezikhukhula ezenzeka eNyakatho Nenkabazwe kubangelwa ukukhishwa kwamagesi abamba ukushisa abangela ukushintsha kwesimo sezulu nokufudumala kwembulunga yonke. Ukuze uthole ulwazi olwengeziwe ngalokhu, ungabheka isihloko esithi igagasi elisha lokushisa ezithinta izifunda eziningana.
Ubudlelwano phakathi kwamazinga okushisa aphezulu kanye nesimo sezulu esibi kakhulu buyabonakala. Ngokusho kwezifundo eziningi, kuye kwaqoshwa amarekhodi okushisa okungabonakali emashumini eminyaka, kwengeza ingcindezi kuma-ecosystem asevele entekenteke. Ngaphezu kwalokho, lokhu kwenyuka kwezinga lokushisa kunomthelela imfuyo ngezindlela ezahlukahlukene
Ukubikezela ikusasa
Ukuze ukwazi ukubikezela kahle okuzokwenzeka ngokuzayo, kudingeka izilinganiso nokubuka okunokwethenjelwa ngangokunokwenzeka. Kuyadingeka ukwazi, ngokuya ngokuhluka okuguqukayo ngokuhamba kwesikhathi, ukuthi iplanethi yethu izosithinta kanjani ngqo nangokungaqondile. Kuwusizo kakhulu ukubikezela ikusasa ngokuhlaziya okwedlule. Ngokutadisha izinguquko zesimo sezulu esidlule, amamodeli angenziwa ukusiza ukubikezela ikusasa. Singazi ngokuqiniseka ukuthi iziguquguquko ezithile zezezulu zingashintsha kanjani ngenxa yokwanda kwegesi ebamba ukushisa. Ngale ndlela, singabikezela ukuthi bazokwenza kanjani namuhla nokuthi yini okufanele yenziwe ukugwema umonakalo omkhulu ngangokunokwenzeka.
Kukososayensi ukuthi bahlole izimbangela, imiphumela, kanye nokuvela kwesimo sezulu kuwo wonke umlando woMhlaba nakusasa. Abezombusazwe, bona, kufanele balalele ongoti futhi basekele izinqumo zabo kwimininingwane yesayensi. Kepha ngaphezu kokubheka ubufakazi obukhonjiswa ososayensi, kubalulekile, ukuze kuzuze bonke, ukuthi abakushoyo kuqondwe kahle. Kodwa-ke, inqubomgomo esobala yaseMelika iphendukela empini yokugwema ukuguquka kwesimo sezulu nayo Ukuhoxa kukaDonald Trump Esivumelwaneni saseParis. Ukuze uqonde kangcono umthelela we- izinga lokushisa lolwandle ekushintsheni kwesimo sezulu, kubalulekile ukucabangela lezi zici.
Ucwaningo lwe izinguquko ezimweni zesimo sezulu Isekelwe ekuqoqweni kwedatha evela ezikhathini ezahlukene, okusiza ukubikezela isomiso nezikhukhula ezizayo. Ngalo mqondo, isimo se- isomiso eSpain kuphakamisa ukukhathazeka okukhulu.
Imizamo yokunqanda ukuguquguquka kwesimo sezulu ayanele
Kuyadabukisa ukubona imiphumela yokuguquguquka kwesimo sezulu ibonakala kakhulu nsuku zonke, njengoba izinhlekelele zibulala izinkulungwane zabantu unyaka nonyaka, nokho imizamo yokumisa ukufudumala komhlaba ayanele. Noma ngabe wonke amazwe emhlabeni ahambisana neSivumelwano saseParis kule ncwadi, amazinga okushisa aphakathi nendawo azokhuphuka ngaphezu kwama-2 degrees asungulwa umphakathi wesayensi njengomkhawulo. Izinselelo ezidalwa wukuguquka kwesimo sezulu zibalulekile futhi ziyaphuthuma. Izixazululo ziyinkimbinkimbi, phakathi kwezinye izinto, ngoba zidinga izivumelwano zamazwe ngamazwe, isenzo esisheshayo nesesikhathi eside, futhi sisebenza ngokukhululekile. Ebhekene nenkinga enkulu kangaka nokubaluleka komhlaba jikelele, ukubamba iqhaza kwabo bonke kuyadingeka, ikakhulukazi kulabo abanamakhono amaningi futhi abangasiza kakhulu.
Izinguquko esivele sizibona emvelweni zikhomba ukuthi ziningi izifunda zomhlaba bahlupheka kakhulu ngenxa yokwehla kwemithombo yamanzi ngenxa yesomiso esidonsa isikhathi eside. Kubalulekile ukuqapha umthelela wamagagasi okushisa kulezi zindawo zemvelo ezisengozini.
