Ngaphandle kwezimvo zamanani oluntu afana nowayesakuba nguMongameli wase-US uDonald Trump, othe ngamaxesha athile wachaza utshintsho lwemozulu “njengenkohliso” yiTshayina ejolise ekuzuzeni uqoqosho, ubunyani besayensi buyothusa. Ingxelo enesihloko UVavanyo lweMozulu yeSizwe umisele ukuba Abantu babekek’ ityala ngokuyintloko ngotshintsho esilubonayo kwiatmosfera..
Ukutshintsha kwemozulu asiyonto intsha; kwenzekile kuyo yonke imbali yoMhlaba. Nangona kunjalo, into eyothusayo malunga nemeko yangoku kukuba Zange ngaphambili ukuba uhlobo oluthile lube nempembelelo enzulu ngolu hlobo kwisijikelezi-langa. Imisebenzi yabantu iguqula imozulu ngesantya esingazange sabonwa xa kuthelekiswa nemijikelo yendalo yokutshintsha kwemozulu eyenzeka kwixesha elidlulileyo.
Yintoni unobangela wotshintsho lwemozulu yangoku?
Abona nobangela baphambili botshintsho lwemozulu lwangoku kukuqhubeka kuphuma iigesi zegreenhouse, ngakumbi icarbon dioxide (CO2), emoyeni. Ezi zinto zikhutshwayo ziphuma ekutshisweni kwamafutha efosili afana namalahle, ioli, negesi yendalo, kwakunye nokugawulwa kwamahlathi nezolimo. I Ukuba sesichengeni kweSpain malunga nokutshintsha kwemozulu, lo ngumba ekufuneka nawo uqwalaselwe.
Ngokutsho kwe Ingxelo yoVavanyo lweMozulu yeSizweukususela ngo-1950 ukuza kuthi ga ngoku, igalelo lomntu kutshintsho lwemozulu luphakathi kwe-92% kunye ne-123%, ngeyona pesenti iphakamileyo ichazwa yimisebenzi yabantu echasene nemiphumo yeziganeko zendalo, ezinjengokudubula kwentaba-mlilo. Nangona kunjalo, i Ukukhutshwa kwerhasi yeGreenhouse kungaphaya kwamandla oMhlaba okufunxa ezi gesi.
Iziphumo esele zibonwa eMhlabeni
Njengoko umndilili wobushushu behlabathi unyuka, iilwandle zinotshintsho oluxhalabisayo. Amanzi olwandle Iya isiba shushu, ibe neasidi ngakumbi kwaye inamanqanaba asezantsi eoksijini., eneziphumo ezimandundu kwizinto eziphilayo zaselwandle kunye nenkqubo yendalo engaselunxwemeni. Nangona kunjalo, iziganeko ezifana neNkanyamba uOphelia ngumzekelo ocacileyo wempembelelo yolu tshintsho.
Kwakhona, Ukunyibilika okukhawulezileyo kwezibonda kubangela ukunyuka komphakamo wolwandle, ezisongela uluntu oluselunxwemeni kwihlabathi jikelele. Iziganeko zemozulu ezimandundu, ezinjengezaqhwithi nezaqhwithi, nazo ziya zisanda. Iintlekele ezifana Irma o Harvey yimizekelo ecacileyo yokwanda kobundlobongela kwezi ziganeko zendalo.
Iigesi zeGreenhouse kunye neempembelelo zazo
Iigesi zeGreenhouse zikhompawundi kwiatmosfera ezibamba ubushushu, kwaye ngelixa ezinye zisenzeka ngokwemvelo, izinto ezenziwa ngabantu ziye zakwandisa kakhulu ukugxila kwazo. Iigesi eziphambili ziquka:
- icarbon dioxide (CO2)
- methane
- i-nitrous oxide
- iigesi ezinefluorinated
I-CO2, ngokukodwa, i-greenhouse gas ibaluleke kakhulu enxulumene nomsebenzi womntu. Ngo-2020, ukugxininiswa kwayo kuye kwanda 48% ngaphezulu kwamanqanaba angaphambi kwamashishini (ngaphambi kowe-1750). Olu lwando luyimbangela yokukhathazeka, njengoko Uqikelelo lubonisa ukunyuka okunokwenzeka kobushushu nto leyo enokuyenza mandundu ngakumbi imeko.
Indima yomsebenzi womntu ekutshintsheni kwemozulu
Ixesha elidlulele, Izinto ezenziwa ngabantu ziye zaba negalelo elikhulu ekukhutshweni kwegesi yegreenhouse. Eminye yemisebenzi eyingozi kakhulu ibandakanya:
- Ukuvelisa amandla: Imveliso yombane evela kumafutha efosili inoxanduva lwenxalenye enkulu yokukhutshwa kweCO2 yehlabathi.2.
- Ezothutho: Ukusetyenziswa kweenqwelo-mafutha, iinqanawa, neenqwelo-moya ezixhomekeke kumafutha efosili kunegalelo elikhulu ekwandeni kweegesi ze<em>greenhouse.
- Ukutshatyalaliswa kwamahlathi: Ukutshatyalaliswa kwamahlathi akukhuphi kuphela iCO egciniweyo2 kodwa ikwanciphisa isakhono sesijikelezi-langa sokufunxa le gesi.
- Imveliso yokutya: Ulimo lwale mihla, ngakumbi ukufuya imfuyo, luvelisa izixa ezikhulu zemethane kunye ne-nitrous oxide.
Ibalulekile loo nto Amazwe, amashishini kunye nabantu ngabanye bayasebenzisana ukunciphisa ukukhutshwa kwegesi ye-greenhouse ukuba sifuna ukunciphisa ezona ziphumo zinzima zokutshintsha kwemozulu. Oku kunokubonwa kwi ingxoxo ngeziphumo zexesha elizayo zokutshintsha kwemozulu, ebonisa ukungxamiseka kwesenzo.
Los amahlathi abalulekile ukulwa nokutshintsha kwemozulu, kwaye kubalulekile ukuqonda indlela abachaphazelekayo ngayo, njengoko kuchazwe kwinqaku iilebhu zendalo eSpain.
Amanyathelo okulwa nokutshintsha kwemozulu
Kukho iindlela ezininzi apho umntu ngamnye anokunceda ukulwa nokutshintsha kwemozulu:
- Nciphisa ukusetyenziswa kwamandla: Sebenzisa imithombo yamandla ahlaziyekayo nanini na kunokwenzeka, njengamandla elanga okanye omoya, kwaye wonge ngakumbi umbane ekhaya.
- Khuthaza ukusetyenziswa kwezithuthi ezizinzileyo: Ukukhetha ukuhamba, ukujikeleza, ukusebenzisa izithuthi zikawonkewonke okanye iimoto zombane kunokunciphisa kakhulu ukukhutshwa kweCO2.2.
- Xhasa ukugawulwa kwamahlathi: Ukutyala imithi kunye nokukhusela amahlathi asele ekhona ziintshukumo ezibalulekileyo zokufunxa iCO2.
- Khuthaza isondlo esizinzileyo: Ukunciphisa ukusetyenziswa kwenyama kunye nokukhetha iimveliso zasekhaya, zamaxesha onyaka kunokunciphisa ukukhutshwa kwezinto ezinxulumene nezolimo.
Ukutshintsha kwemozulu yingxaki yehlabathi efuna inyathelo elidityanisiweyo nelilungelelanisiweyo kuwo onke amanqanaba oluntu ukuze kulungiswe ngokufanelekileyo. Ukusuka ekwamkeleni imigaqo-nkqubo yoluntu ekhuthaza ukuzinza ekutshintsheni imikhwa yomntu ngamnye, sonke sinokufaka isandla ekunciphiseni le nto. Ixesha lokuthatha amanyathelo ngoku. Ngolwazi oluthe kratya, ungajongana nathi
