Kusekho abantu abaninzi ehlabathini abangakholelwayo kutshintsho lwemozulu (njengoMongameli waseMelika, uDonald Trump). Nangona kunjalo, Utshintsho lwemozulu luyinyani kwaye kuya kusanda ukubaluleka ukuluyeka, kuba iziphumo zayo ziyabatshabalalisa abantu kunye nezinto eziphilayo.
Ngaba uyafuna ukwazi obona bungqina bucacileyo bokuba utshintsho lwemozulu lukhona?
Utshintsho lwemozulu
Kwiplanethi yethu yonke into inxulumene nayo yonke into inxibelelana nezinye izinto. Izinto eziphilayo zidinga iimeko ezithile zobomi ukuze uphile kakuhle. Utshintsho lwemozulu lubangela iintlobo ezininzi zezilwanyana, izityalo, iintsholongwane, njl. Baphelelwa yindawo yabo yokuhlala apho banokukhula kwaye baphile kakuhle. Umzekelo, ekuqaleni kuka-Okthobha, ezinye zeewarrus ezingama-35.000 zafika kunxweme lweAlaska ngenxa yokunqongophala komkhenkce kwiArctic. Bafuna umkhenkce ukuze bakwazi ukuphumla kunye nokuphumla kwaye ikwayiyo nendawo yokuhlala yendalo.
Esi siganeko asikho okokuqala ukuba senzeke, kodwa sinike okuninzi ukuba sithethe ngako. Kwapapashwa into yeendaba ephawula ngeli phepha leewalrus ezichaza ukuba utshintsho lwemozulu yinto eyinyani kwaye iyasichaphazela sonke. Unyaka ngaphambi kwento eyenzekileyo, nayo Malunga ne-10.000 walruses zarekhodwa e-Alaska Beach ngesizathu esinye: Kukho umkhenkce omncinci nangaphantsi kulwandle lweArctic, ke abanandawo yokuphumla kwaye bahlala ngoxolo.
Into exhalabisayo ngemeko yenguqu yemozulu kukuba iziphumo zayo zibonakaliswa ngendlela engalindelekanga esingakulungelanga ukuyilwa okanye ukuyinciphisa. Oku kuthetha ukuba, kwabanye, le nto ayisiyonyani njengabanye kwaye izoyikiso zayo azibonakali.
Izizathu ezili-10 zokuba kutheni utshintsho lwemozulu luyinyani
Ukuthintela ukubhideka kwabantu malunga nokuba utshintsho lwemozulu luyinto yokwenyani na okanye hayi, ndiza kunika izizathu ezili-10 ezibonisa ukuba ikhona, kwaye neziphumo zayo ziya zisanda kwaye ziyatshabalalisa.
- Phakathi kowe-1982 ukuya kowama-2010, kwapapashwa iincwadi ezili-108 zemfundo ezaziphika ubukho botshintsho lwemozulu. Yiipesenti ezingama-90 kuphela zelo nani ezaziphononongwa ngoontanga.
- Nje I-0,01% yazo zonke izazinzulu emhlabeni azikholelwa kutshintsho lwemozulu.
- Ngo-1985 uSvante Arrhenius, ugqirha wamachiza waseSweden kunye nosokhemesti, wazisa okokuqala iphepha elichaza iimpembelelo zokunyuka kwekharbon dayoksayidi emhlabeni kunye nefuthe lobushushu.
- Ngokwenzululwazi yoluntu kunye neengcali ezivela kwi-Intergovernmental Panel on Climate Change (IPCC), ukuba ubushushu beplanethi bunyuke ngamaqondo amabini ngaphezu komndilili, iyakuba neziphumo ezibi kakhulu nezingenakulungiseka ebantwini.
- Amadoda singakhupha iitoni ezingama-800.000.000.000 iimethrikhi zekhabhon dayoksayidi esemoyeni ngaphambi kokufikelela konyuka nge-2 ° C kubushushu beplanethi.
- Nangona kubonakala ngathi utshintsho lwemozulu aluyonyani kwabaninzi, kuqikelelwa ukuba bamalunga nama-400.000 abantu ababhubha nyaka ngamnye kwizizathu ezinxulumene noko. Isenokuba sele ikukunyuka kwezikhukula, iinkanyamba kunye nembalela.
- Bekuphakathi kweminyaka engama-800.000 ukuya kwi-15.000.000 yeminyaka ukusukela oko amanqanaba ecarbon dioxide emoyeni ayephezulu njengokuba enjalo ngoku.
- Ukusukela oko kwafika uhlengahlengiso kwimizi-mveliso, icarbon dioxide esemoyeni inyuke nge-142 yepesenti.
- I-25% yolonyuso kwi-CO2 yenzeke kuphela phakathi kwe-1959 kunye ne-2013.
- Ngowama-2010, ilahleko ye-GDP kwihlabathi jikelele eyona nto ibangele utshintsho lwemozulu yafikelela kwi-696.000.000.000 yezigidi.
Njengoko ubona, kukho izizathu ezinokuthenjwa zokuthi utshintsho lwemozulu lukhona kwaye luyinyani. Iziphumo zalo ziyanda ngakumbi nangakumbi kwaye iziphumo zibuhlungu. Utshintsho lwemozulu luchaphazela onke amazwe omhlaba ngokungalingani, kodwa abona bantu basemngciphekweni ngabo bangabona bahlwempuzekileyo kunye nabo banobuncinci bokukwazi ukunciphisa kunye nokulwa nalo. Yiyo loo nto oorhulumente kwihlabathi liphela bezama ukulwa notshintsho lwemozulu ngendlela elinganayo.
