Kuyini Ukungathathi-hlangothi Kwekhabhoni?
Ukungathathi hlangothi kwekhabhoni kubhekisela enanini eliphelele lekhabhoni dioksijini noma ukukhishwa kwegesi yokushisa okukhiqizwe ngokuqondile noma ngokungaqondile yizwe, ibhizinisi, umkhiqizo, umsebenzi noma umuntu ngaphakathi kwesikhathi esithile, ngokusebenzisa amandla aphansi ekhabhoni ukufaka esikhundleni samafutha emvelo, ukutshalwa kwamahlathi, ukonga amandla kanye nokunciphisa ukukhishwa kwegesi kanye nezinye izindlela zokunciphisa ukukhishwa kwegesi yokushisa okukhiqizwe ngokwako, ukuthola imiphumela emihle nemibi, kanye nokufeza "ukukhishwa kwegesi okungekho".
Ngokuvamile kunezindlela ezimbili zokufeza ukungathathi hlangothi kwekhabhoni:
Ngokusebenzisa indlela yokukhipha ikhabhoni, ukukhishwa kwekhabhoni okukhiqizwa yiyo kufana nokukhishwa kwekhabhoni okuncishisiwe kwenye indawo. Isibonelo: ukutshala izihlahla, ukuthengwa kwamavawusha amandla avuselelekayo.
Ukusetshenziswa kobuchwepheshe be-carbon ephansi noma engenalutho (bheka umnotho we-carbon ephansi). Njengokusetshenziswa kwemithombo yamandla avuselelekayo (njengomoya namandla elanga) ukugwema ukukhishwa kwe-carbon dioxide emkhathini ngenxa yokushiswa kwamafutha e-fossil; umgomo wokugcina ukusebenzisa imithombo yamandla e-carbon ephansi kuphela esikhundleni samafutha e-fossil, ukuze ukukhishwa kwe-carbon kanye nenani le-carbon elimuncwa emhlabeni lilingane kungakhuphuki.
Ukukhokha amanye amazwe noma izifunda ngokuhweba ngekhabhoni ukuze uthole amalungelo awo okukhipha ikhabhoni kungasindisa izindleko ngenkathi kugcina umgomo wokunciphisa ukukhishwa kwekhabhoni ungashintshi; kodwa ngoba le ndlela ayifezi ngempela umphumela wokunciphisa inani eliphelele lekhabhoni diokside.
Umthelela wekhabhoni uyisibonakaliso esibalulekile sokuthi kufanele kufinyelelwe yini ukungathathi hlangothi kwekhabhoni. Ngezinye izikhathi akucatshangelwa i-carbon dioxide kuphela, kodwa futhi kufakwa nokukhishwa kwamanye amagesi okushisa (njenge-methane).
UKehui uzohambisana nokuzibophezela kokungathathi hlangothi kwekhabhoni, anciphise ukukhishwa kwekhabhoni, asebenzise ubuchwepheshe bokukhipha i-carbon ephansi noma i-zero-carbon, futhi afake isandla ekuvikelweni kwemvelo kweShayina kanye nokunciphisa ukufudumala komhlaba. UKehui unxusa wonke umuntu: hlalani ndawonye ngokungachemi kwekhabhoni, wonke umuntu unesibopho sokuvikela umhlaba!
