Iplanethi yethu iphantsi kwenani elikhulu leziganeko zemozulu ezibi kakhulu. Ngoku ehlotyeni, ngokwanda kwamaqondo obushushu nokuhla kwemvula, amaxesha okoma aqala. Imbalela iyingozi ebantwini nasezintlobo zezityalo nezilwanyana.
Amanzi ayafana nobomi kwaye iya isanda rhoqo, imbalela enkulu kunye nehlala ixesha elide itshabalalisa intsalela yezinto eziphilayo. Le mbalela iyandiswa nangakumbi ziziphumo zokutshintsha kwemozulu.
Ukwanda kwembalela namaqondo obushushu
Kwiminyaka yakutshanje, ukuphakama kwembali kuye kwarekhodwa kwiiparameter ezahlukeneyo zehlabathi ngenxa yeziganeko zemozulu ezibi kakhulu. Amaqondo obushushu aphezulu, amanqanaba emvula agqithisileyo, isantya somoya ogqithileyo, njl. Umzekelo, Le Aprili yamandulo yayiyeyona ishushu kwiminyaka eyi-137. Ulawulo lwe-Oceanic kunye ne-Atmospheric Administration (i-NOAA) yase-United States lubonisa ukuba ngo-Epreli ka-2016 nango-2017 ezona zinto zimbini zibalaseleyo kubushushu baselwandle zibhalisiwe ukusukela ngo-1880. Uxinzelelo lweegesi zegreenhouse emoyeni. NgoJuni 14, 2017, Ubushushu boxinaniso lwe-CO2 lwengxenye ezingama-409,58 kwisigidi ngasinye (ppm) zarekhodwa, umlinganiso oqinisekisa ukuqhubeka kokonyuka kwee-greenhouse gases kunye neyona ndawo iphakamileyo ephezulu ye-CO2 efunyanwa eMhlabeni iminyaka engama-800.000.
Kumele kuthathelwe ingqalelo ukuba ukubaluleka kokukhutshwa kwegesi yendlu eluhlaza sisenzo somntu kunye nefuthe lazo kwimozulu ayinakuphikwa. Kukho izifundo ezichaza ukuba ubushushu bomhlaba benziwe ngumntu Utshintsho olusemoyeni luyatshintsha. Oku kubangela ukuphindaphindeka kunye nokuqina kweziganeko zemozulu ezibi kakhulu ezenzekayo nazo ziyanda. Amaza amaninzi obushushu kunye nezikhukula kuMantla eIkhweyitha zibangelwa kukukhutshwa kwegesi ebamba ukushisa ebangela ukutshintsha kwemozulu kunye nokufudumala komhlaba.
Qikelela ikamva
Ukuze ukwazi ukuqikelela kakuhle ukuba kuzakwenzeka ntoni kwixesha elizayo, imilinganiselo kunye nokuqwalaselwa kuyafuneka ngokuthembekileyo ngangokunokwenzeka. Kuyimfuneko ukwazi, ngokweenguqu eziguqukayo ngokuhamba kwexesha, indlela umhlaba wethu oza kusichaphazela ngayo ngokuthe ngqo nangokungathanga ngqo. Iluncedo kakhulu ukuqikelela ikamva ukuhlalutya elidlulileyo. Enkosi kufundo lweenguqu kwimozulu kwixa elidlulileyo, iimodeli zinokuveliswa ukunceda ukuqikelela ikamva. Ngokuqinisekileyo singazi ukuba iimeko ezithile zemozulu zinokutshintsha njani ngenxa yokonyuka koxinaniso lweegesi zegreenhouse. Ngale ndlela, sinokuqikelela indlela abaza kusebenza ngayo namhlanje kunye nento abanokuyenza ukuthintela owona monakalo mkhulu.
Kuxhomekeke kwizazinzulu ukuba zifunde izizathu, iziphumo, kunye nokuvela kwemozulu kwimbali yomhlaba nakwixesha elizayo. Abezopolitiko, kwelabo icala, kufuneka bamamele iingcali kwaye basekele izigqibo zabo kwidatha yesayensi. Kodwa ukongeza ekuqwalaseleni ubungqina obuboniswa ngoososayensi, kubalulekile, ukuze kulungelwe bonke, ukuba oko bakuthethayo kuqondwe ngokuchanekileyo. Nangona kunjalo, umgaqo-nkqubo waseMelika ocacileyo ujika kumlo othintela ukutshintsha kwemozulu nge Ukurhoxa kukaDonald Trump kwisivumelwano saseParis.
Iinzame zokuphelisa utshintsho lwemozulu azonelanga
Kulusizi ukubona indlela iziphumo zokutshintsha kwemozulu ezibonakala ngayo yonke imihla kunye neentlekele ezithatha amawaka abantu ngonyaka kodwa ukanti iinzame zokuphelisa ubushushu behlabathi azonelanga. Nangona onke amazwe ehlabathi ethobele isivumelwano seParis ukuya kwimilimitha, amaqondo obushushu aphakathi aya kuphakama ngaphezulu kweedigri ezi-2 ezenziwa luluntu lwenzululwazi njengomda.
Imingeni ebangelwa lutshintsho lwemozulu ibalulekile kwaye ingxamisekile. Izisombululo zinzima, phakathi kwezinye izinto, kuba zifuna izivumelwano zamazwe ngamazwe, inyathelo elikhawulezileyo nelide, kunye nokusebenza ngesisa. Ukujongana nengxaki enkulu kangaka kunye nokubaluleka kwehlabathi, ukuthatha inxaxheba kwabo bonke kuyafuneka, ngakumbi kwabo banamakhono amaninzi kwaye banokufaka igalelo elingaphezulu.
