Nakuba imizamo yomuntu ngamunye ibalulekile, kubalulekile ukuqaphela ukuthi izenzo ezinkulu zezinkampani kanye nohulumeni ziyadingeka ukuze kuzuzwe inqubekelaphambili ephusile ekunqandeni ukungcola. Amazwe anemali engenayo ephezulu, ikakhulukazi, anesibopho esikhulu sokuhola le mizamo ngenxa yesabelo sawo esingalingani sokukhishwa kwekhabhoni.
Hlanganyela nathi njengoba sihlola ubunkimbinkimbi bokuguquguquka kwesimo sezulu futhi wembula izinyathelo esingazithatha ukuze sivikele iplanethi yethu izizukulwane ezizayo.
Njengoba amazinga okushisa embulunga yonke eqhubeka nokukhuphuka ngokunganqamuki, imithelela yokushintsha kwesimo sezulu iya iba njalo, ishube kakhulu, ibe yingozi kakhulu futhi isakazeke kakhulu. Amazinga olwandle ayakhuphuka, izinguzunga zeqhwa ziyancibilika, amazinga okushisa ayanda kanye nezimo zezulu ezimbi ziya ngokuya ziba yinsakavukela. Kodwa akuzona zonke izindaba ezibuhlungu. Naphezu kokunyuka kokukhathazeka ngekusasa leplanethi , siyazi ukuthi yini okufanele siyenze - kunezinyathelo eziningi ezisekelwa isayensi zokunciphisa imithelela emibi kakhulu yokushintsha kwesimo sezulu .
Mhlawumbe isinyathelo sokuqala siwukuqinisekisa ukuthi siyaqonda ukuthi kuyini ukuguquka kwesimo sezulu , kanye (ngaphezu koshintsho lwesistimu oludingeka kakhulu) ukuthi sonke singabamba iqhaza kanjani emzamweni wokulwa nokushisa komhlaba .
Kuyini Ukuguquka Kwesimo Sezulu?
Ezingeni eliyisisekelo kakhulu, ukuguquka kwesimo sezulu kulapho isimiso sezulu somhlaba sishintsha kakhulu futhi sibonisa izimo zezulu ezintsha. Izinguquko zesimo sezulu zingaba “zifushane” emashumini ambalwa eminyaka noma zihlale isikhathi eside njengezigidi zeminyaka. Isibonelo, i-CO2 ingahlala emkhathini iminyaka engu-300 kuya kweyi-1000 , kuyilapho i-methane ihlala emkhathini cishe iminyaka eyi-12 (nakuba i-methane nayo inamandla futhi ilimaza).
Kunomehluko phakathi kwesimo sezulu nokushintsha kwesimo sezulu . Amazinga okushisa ayashintshashintsha ngokwezinto eziphilayo phakathi nesikhathi sempilo yoMhlaba. Kodwa inani lokuguquguquka kwesimo sezulu esilibonayo manje liwumphumela kakhulu wezinto ezenziwa abantu - ikakhulukazi, imisebenzi yabantu ekhiqiza amagesi abamba ukushisa, ikakhulukazi i-carbon dioxide (CO2), i-methane (NH4) ne-nitrous oxide (NO2).
Inkinga ngamagesi abamba ukushisa ukuthi abamba ukushisa emkhathini woMhlaba, okwandisa izinga lokushisa lomhlaba wonke. Ngokuhamba kwesikhathi, lawa mazinga okushisa aphezulu akhubaza amaphethini esimo sezulu akhona kanye nesimiso semvelo, futhi lokhu konakala kuba nomthelela omubi othinta yonke into kusukela ekukhiqizeni izitshalo nokuhlukahluka kwemvelo kuya ekuhleleni amadolobha, ukuhamba ngendiza namazinga okuzalwa . Mhlawumbe okucindezela kakhulu, ukufudumala kwembulunga yonke kubeka engcupheni ikhono lethu lokutshala ukudla kwabantu abacishe babe izigidi eziyizinkulungwane eziyi-10 abayogcwala umhlaba ngonyaka ka-2050.
Okushintsha ukushintsha kwesimo sezulu kube isimo esiphuthumayo isivinini isimo sezulu esishintsha ngaso , kanye nemiphumela engaba yinhlekelele uma singaguquli ngendlela emangalisayo. Eziningi zalezi zinguquko zidinga abenzi bezinqubomgomo nabalawuli ukuthi bangenelele, kodwa abanye bangenza okungenani umehluko othile ezingeni lomuntu ngamunye, futhi lokhu kufaka phakathi izinguquko ezilula zokudla ezingase zinciphise kakhulu umthelela wezolimo kanye nokugawulwa kwamahlathi emazingeni okukhishwa kwegesi emhlabeni jikelele.
Ukushintsha kwesimo sezulu okubangwa amagesi abamba ukushisa kubizwa ngokuthi “ ukuguquka kwesimo sezulu se-anthropogenic ” ngoba kuwumphumela wezinto ezenziwa abantu, hhayi intuthuko yemvelo yoMhlaba. Izimoto, amandla namandla okukhiqiza amandla, nezinqubo zezimboni kanye nezolimo (ngokuyinhloko ukukhiqizwa kwenyama yenkomo nobisi ), kuyimithombo eyinhloko yalezi zigesi .
Kungani Kwenzeka Ukushintsha Kwesimo Sezulu?
Nakuba okunye ukuguquka kwesimo sezulu kuyinto evamile, izinguquko ezimbi kakhulu esizibonile emashumini ambalwa eminyaka adlule ngokuyinhloko ziwumphumela wemisebenzi yabantu. abakhulu balolu shintsho amagesi abamba ukushisa , akhululwa endaweni ezungezile njengomphumela wemisebenzi ehlukahlukene yabantu yansuku zonke.
Indlela osebenza ngayo ichazwa yi-greenhouse effect, inqubo yemvelo lapho umkhathi ophansi woMhlaba ubamba ukushisa okuvela elangeni, njengengubo. Le nqubo ayimbi ngokwemvelo; empeleni, kuyadingeka ukugcina impilo Emhlabeni , njengoba igcina izinga lokushisa leplanethi ngaphakathi kwebanga eliphilayo. Kodwa-ke, amagesi abamba ukushisa akhulisa umphumela we-greenhouse ngaphezu kwamazinga awo emvelo, okwenza uMhlaba ufudumale.
Iningi lamagesi abamba ukushisa - cishe amaphesenti angama-73 - kuwumphumela wokusetshenziswa kwamandla yizimboni, izakhiwo, izimoto, imishini neminye imithombo. Kepha umkhakha wokudla uwonke, okubandakanya ukugawulwa kwamahlathi ukuze kuvuleke indawo yemfuyo eningi, unesibopho sengxenye yesine yokukhishwa kwegesi - kanti ngenkathi isabelo esincane sihlanganisa ukusetshenziswa kwamandla, ukukhishwa okuningi okuhlobene nokudla kuqhutshwa ukulima kwenkomo nobisi. Iningi longoti besimo sezulu bathi sidinga ukunqanda ukungcoliswa komoya okuvela kuyo yonke imikhakha, futhi lokho kufaka phakathi lokho esikucabangayo .
Kubukeka Kanjani Ukuguquguquka Kwesimo Sezulu?
Kunobufakazi obuningi obubonisa imiphumela yokushintsha kwesimo sezulu se-anthropogenic , futhi ngokusho kocwaningo oluningi olwenziwe ososayensi besimo sezulu , sidinga ukuthatha isinyathelo esiphuthumayo sokubuyisela emuva le miphumela ukuze sigweme ukwenza iplanethi ingabi nomoya wokungenisa izihambi kubantu. Nansi eminye yaleyo miphumela, eminingi yayo ebuyela emuva futhi ithonyane.
Amazinga Okushisa Akhuphukayo
Amazinga okushisa akhuphukayo ayingxenye eyinhloko yokufudumala kwembulunga yonke. Ososayensi bebelandelela amazinga okushisa omhlaba kusukela ngo-1850, kanti iminyaka eyi-10 edlule - okungukuthi, isikhathi esiphakathi kuka-2014 no-2023 - bekuyiminyaka eyi-10 eshisa kakhulu emlandweni, kanti u -2023 ngokwawo uwunyaka oshisa kakhulu emlandweni. Okubi nakakhulu, u-2024 ubonakala enethuba elilodwa kwamathathu okushisa kakhulu kuno-2023. Ngaphezu kwamazinga okushisa aphezulu, ukuguquka kwesimo sezulu kukhulise ukuqina, imvamisa kanye nobude bamagagasi okushisa abulalayo emhlabeni jikelele .
Izilwandle Ezishisayo
Ulwandle lumunca ukushisa okukhulu okubangelwa amagesi abamba ukushisa, kodwa lokho kungenza nolwandle lushise kakhulu. Izinga lokushisa lolwandle, lifana nezinga lokushisa lomoya, lalishisa kakhulu ngo-2023 kunanoma yimuphi omunye unyaka , futhi kulinganiselwa ukuthi ulwandle lumunce ngaphezu kwamaphesenti angu-90 okufudumala komhlaba kusukela ngo-1971 . Izinga lokushisa lolwandle linethonya elikhulu ezimeni zesimo sezulu, isayensi yezinto eziphilayo zasolwandle, amazinga olwandle kanye nenani lezinye izinqubo ezibalulekile zemvelo.
Ikhava Yeqhwa Encane
Iqhwa lidlala indima ebalulekile ekulawuleni amazinga okushisa oMhlaba ngenxa yomphumela we-albedo — okungukuthi, iqiniso lokuthi izindawo ezinombala okhanyayo zibonisa imisebe yelanga kunokuba ziyimunce. Lokhu kwenza iqhwa libe yi-ejenti yokupholisa, futhi nokho ukushintsha kwesimo sezulu kubangele ukwehla okukhulu kokumboza kweqhwa emhlabeni jikelele.
Eminyakeni eyikhulu edlule noma ngaphezulu, isilinganiso sekhava yeqhwa ngo-April e-US . lehle ngamaphesenti angaphezu kwangu-20, futhi kusukela ngo-1972 kuya ku-2020, indawo evamile embozwe iqhwa yehle cishe ngamamayela-skwele angu-1,870 ngonyaka . Umjikelezo ononya: izinga lokushisa elishisayo libangela ukuba iqhwa lincibilike, futhi ukuncipha kweqhwa kubangela amazinga okushisa ashisayo.
Ancipha Ama-Ice Sheets nama-glaciers
Amaqhwa anamanzi amaningi ahlanzekile ayiqhwa, futhi amboza indawo engaphezulu kangangokuthi athonya isimo sezulu embulungeni yonke. Kodwa sekungamashumi eminyaka iqhwa emhlabeni lincipha. Indawo yeqhwa yaseGreenland - enkulu kunazo zonke emhlabeni - yehle cishe ngamamayela-skwele ayi-11,000 emashumini amathathu eminyaka adlule, futhi ilahlekelwe amathani ayizigidi eziyizinkulungwane ezingama-270 wesisindo minyaka yonke , ngokwesilinganiso, phakathi kuka-2002 no-2023. Iqhwa liyancibilika, amazinga olwandle omhlaba wonke azokhuphuka, okuzobeka iMiami, i-Amsterdam namanye amadolobha amaningi asogwini ngaphansi kwamanzi .
Izinguzunga zeqhwa emhlabeni wonke nazo ziyawohloka. I-Tibetan Plateau nezindawo ezizungezile, okuhlanganisa nezintaba ze-Himalaya, zinezinguzunga zeqhwa eziminyene kakhulu ngaphandle kwezifunda ezishisayo, kodwa zincibilika ngokushesha kangangokuthi ngokusho kwabacwaningi, iningi lezinguzunga zeqhwa enkabeni naseMpumalanga yeHimalaya zingase zinyamalale ngokuphelele ngo-2035. Lokhu okutholakele kuthinta ikakhulukazi uma kubhekwa ukuthi lezi zinguzunga zeqhwa zidla imifula emikhulu, njenge-Indus, ehlinzeka ngamanzi abalulekile ezigidini zabantu ezansi nomfula, futhi cishe azophelelwa amanzi maphakathi nekhulu leminyaka uma ukuncibilika kweqhwa kuqhubeka.
Amazinga Olwandle Akhuphukayo
Ukushintsha kwesimo sezulu kubangela ukuthi amazinga olwandle anyuke ngezindlela ezimbili. Okokuqala, njengoba amaqhwa nezinguzunga zeqhwa zincibilika, zithela amanzi engeziwe olwandle. Okwesibili, amazinga okushisa aphezulu abangela ukwanda kwamanzi olwandle.
Kusukela ngo-1880, amazinga olwandle asevele ekhuphuke cishe ngamasentimitha angu-8-9 , futhi ngeke agcine lapho. Amazinga olwandle njengamanje akhuphuka ngenani lamamilimitha angu-3.3 ngonyaka , futhi ososayensi babikezela ukuthi phakathi kuka-2020 no-2050, azokwenyuka ngamayintshi angu-10-12 engeziwe . Abanye ososayensi babikezela ukuthi iJakarta, idolobha elihlala abantu abangaphezu kwezigidi eziyi-10, izobe isingaphansi kwamanzi ngokuphelele ngo-2050 .
I-Ocean Acidification
Lapho izilwandle zimunca isikhutha esisemkhathini, ziba ne-asidi eyengeziwe. Amanzi olwandle ane-Acid avimbela ukubala, inqubo izilwane ezinjengeminenke, ukhwathu nezinkalankala ezithembele kuyo ukuze zakhe amagobolondo kanye namathambo azo. zomhlaba sezine-asidi ecishe ibe ngamaphesenti angu-30 phakathi namakhulu amabili eminyaka adlule, futhi ngenxa yalokho, ezinye izilwane empeleni ziyancibilika emanzini njengoba i-pH ephansi ibangela ukuba amagobolondo namathambo ahlakazeke ancibilike. Okukhathaza nakakhulu, lezi zinguquko zenzeka ngokushesha okukhulu kunanoma yisiphi isikhathi eminyakeni eyizigidi ezingu-300 edlule.
Imicimbi Yesimo Sezulu Esidlulele
Eminyakeni engu-50 edlule, inani lezinhlekelele ezihlobene nesimo sezulu liye landa ngokuphindwe kahlanu , ngenxa yokushintsha kwesimo sezulu. I-California iye yabhekana nochungechunge lwemililo yequbula eminyakeni yamuva nje; imililo yequbula ka-2018 yashisa umhlaba omningi kuhulumeni kunanoma yimuphi omunye umlilo kusukela ngo-1889, futhi imililo ka-2020 yashisa umhlaba omningi kunalokho. Ngo-2020, inhlupho yesikhonyane engakaze ibonwe yehlela eMpumalanga Afrika naseMpumalanga Ephakathi, ishwabadela izitshalo futhi isongela nokutholakala kokudla esifundeni. E-Bay of Bengal, i-super-cyclone Amphan yabulala amakhulu abantu futhi yabangela izikhukhula ngo-2020. Amagagasi okushisa nawo aya ngokuya avama; ngo-2022, abantu babulawa ukufa okuhlobene nokushisa ngenani eliphakeme kakhulu eminyakeni engaphezu kwamashumi amabili.
Liyini Ikhambi Lokushintsha Kwesimo Sezulu?
Yize singekho isisombululo esisodwa sokubhekana nokushintsha kwesimo sezulu se-anthropogenic, ososayensi besimo sezulu bancome izinqubomgomo eziningi nezinguquko zezenhlalo, okuthi, uma zisetshenziswa, zisize ukubuyisela emuva imiphumela emibi kakhulu. Ezinye zalezi zincomo zenzeka ezingeni lomuntu ngamunye, kanti ezinye zidinga isinyathelo esikhulu noma sikahulumeni.
- Ukutshala imali kwezinye izindlela eziluhlaza esikhundleni sezibaseli ezimbiwa phansi. Lesi mhlawumbe isinyathelo esikhulu kunazo zonke esidingekayo ukuze kugwenywe inhlekelele yesimo sezulu. Izibaseli ezimbiwa phansi zikhipha inqwaba yamagesi abamba ukushisa futhi azitholakali kalula, kuyilapho ezinye izindlela ezifana nokukhishwa komoya nelanga azinawo amagesi abamba ukushisa futhi zivuseleleka ngokungapheli. Ukugqugquzela ukusetshenziswa kwamandla ahlanzekile, ikakhulukazi yizinkampani kanye nasemazweni anemali engenayo ephezulu, kungenye yezindlela ezinkulu zokwehlisa ukukhishwa kwekhabhoni yabantu.
- Ukulondoloza kabusha Ukulondoloza izilwane zasendle, okubizwa ngokuthi i-trophic rewilding , kunamandla amakhulu okunciphisa isimo sezulu. Lapho izinhlobo zezilwane zivunyelwa ukuthi zibuyele emisebenzini yazo ku-ecosystem, i-ecosystem isebenza kangcono futhi ikhabhoni eningi ingagcinwa ngokwemvelo. Ukunyakaza nokuziphatha kwezilwane kungasiza ekusakazeni imbewu futhi itshalwe ezindaweni ezibanzi okusiza izitshalo ukuthi zikhule.
- Ukunciphisa ukudla kwethu inyama nobisi. Ukukhiqiza imikhiqizo yezilwane ezosetshenziswa abantu kukhipha amagesi abamba ukushisa amaningi kakhulu kunokukhiqizwa kwezitshalo ezihlukile ezifana nemifino. Okubi nakakhulu, lapho umhlaba ugawulwa ukuze kuvuleke imfuyo , ukungabi khona kwezihlahla kusho ukuthi i-carbon encane ithathwa emkhathini. Ngakho-ke, ukushintshela ekudleni okuqhubela phambili izitshalo kuyindlela enhle kakhulu yokusiza ukwehlisa ukukhishwa kwe-greenhouse.
Izinto ezimbalwa okufanele ziphawulwe lapha. Okokuqala, nakuba isenzo somuntu esimelene nokushintsha kwesimo sezulu sisihle, inani lenqubekelaphambili edingekayo ukuze kunqandwe ukukhishwa kwesisi lizodinga ngempela imizamo yezinkampani nohulumeni. Iningi lezinto ezikhishwa yi-greenhouse izimboni, futhi ohulumeni kuphela abanamandla omthetho ukuphoqa izimboni ukuthi zenze izinqubomgomo ezivumelana nesimo sezulu.
Okwesibili, ngenxa yokuthi amazwe anemali engenayo ephezulu enyakatho yomhlaba anesibopho sesabelo esingenakulinganiswa sokukhishwa kwekhabhoni , lawo mazwe kufanele abelane ngomthwalo owengeziwe ekwehliseni ukuguquka kwesimo sezulu, okuhlanganisa nokudla kancane inyama yenkomo nobisi.
Yini Eyenziwayo Manje Ukuxazulula Ukuguquguquka Kwesimo Sezulu?
Ngo-2016, amazwe angu-195 kanye ne-European Union basayina i-Paris Climate Accords , isivumelwano sokuqala samazwe ngamazwe esibopha ngokomthetho mayelana nokushintsha kwesimo sezulu. Inhloso yalezi zivumelwano ukunciphisa izinga lokushisa emhlabeni wonke libe “ngaphansi kakhulu” ku-2°C ngaphezu kwamazinga angaphambi kwezimboni ngo-2100 - nakuba ikhuthaza amazwe ukuthi ahlose umkhawulo wokuvelela ongu-1.5°C ngaphezu kwamazinga angaphambi kwezimboni - futhi izwe ngalinye umuntu osayinileyo uyadingeka ukuze athuthukise futhi ethule uhlelo lwawo lokunciphisa ukungcola ngaphakathi kwemingcele yawo.
Abaningi baphikisene ngokuthi lo mgomo awukona ukuvelela ngokwanele , njengoba i-UN Intergovernmental Panel on Climate Change ithe noma yini engaphezu kokwenyuka okungu-1.5° ingase ibangele isimo sezulu esibi kakhulu kanye nokukhuphuka kwezinga lolwandle. Sekuseduze kakhulu ukusho ukuthi izivumelwano zizofeza yini umgomo wazo wesikhathi eside, kodwa ngo-2021, inkantolo yayala inkampani kawoyela iRoyal Dutch Shell ukuthi yehlise ukukhishwa kwayo kwekhabhoni ukuze ihambisane nezivumelwano, ngakho-ke isivumelwano sesivele sinesimo esibonakalayo, umthelela ongokomthetho ekukhiqizweni.
Umugqa Ophansi
Kuyacaca ukuthi uguquko olubanzi lwezinhlelo luyadingeka ukuze kubhekwane nezimbangela zokuguquguquka kwesimo sezulu ezenziwa abantu. Wonke umuntu unendima okumele ayibambe futhi ulwazi luyisinyathelo sokuqala esibheke esenzweni. Kusukela ekudleni esikhetha ukukudla kuye emithonjeni yamandla esiyisebenzisayo, konke kubalwa ekwehliseni umthelela wethu kwezemvelo.
