Nangona bekusoloko kukho utshintsho lwemozulu, le nto sihlangabezana nayo ngoku iye yambi ngenxa yemisebenzi yabantu. Ngakumbi nangakumbi kuthi sihlala kulo mhlaba mncinci uluhlaza, ngenxa yoko ibango le… yonke into (ukutya, izindlu, njalo njalo) liyanda. Konke oku inefuthe elimangalisayo kwimozulu, ukufudumeza ikhaya lethu ngakumbi, ngelixa umkhenkce unyibilika kwaye ubangela, ngale ndlela, ukunyuka kancinci kodwa okuthe rhoqo kumphakamo wolwandle.
Kodwa, Siqala nini ukwaphula ibhalansi yemozulu?
Kwiminyaka yakutshanje, ngakumbi kwiminyaka ye-16 yakutshanje, irekhodi lobushushu elibaluleke kakhulu lophukile. Ngoku, phantse inyanga nenyanga i-mercury inyuka ngaphezulu kunokuba kufanelekile. Nangona kunjalo, ngokophando olulungiselelwe yiAmerican Geophysical Union epapashwe kwijenali yesayensi yeGeophysical Research Letters, ingxaki yavela ngo-1937. Ngaloo nyaka amaqondo obushushu aphezulu ayanyaniswa notshintsho lwemozulu. Emva kwexesha kwavela ezinye, ezizezi: 1940, 1941, 1943-1944, 1980-1981, 1987-1988, 1990, 1995, 1997-1998, 2010 and 2014.
Abaphandi baqonda ukuba ukusetyenziswa gwenxa kweearosol zeshishini kufihla impembelelo abantu abanayo kwimozulu, kuba banefuthe lokupholisa. Kodwa naphina apho sijonga khona siyakufumana iimpawu zotshintsho lwemozulu, okusenza sibe nesijikelezi-langa esishushu.
Iqela livavanye iimeko zemozulu ezigqithe kuluhlu lokwahluka kwendalo, kwaye bagqiba kwelokuba kule minyaka mithandathu idlulileyo belwe iirekhodi ezibalulekileyo, ngakumbi e-Australia, ukusukela ekubeni ikwi-hemisphere esemazantsi, embindini wolwandle, ihlala ikude nefuthe lokubanda kweerosols.
Iierosol kwindawo ezixineneyo zibonisa ubushushu obungaphezulu, obubuyiselwa emajukujukwini, kodwa buye bususwe kungekudala emoyeni, ubushushu buyabuya. Le mpembelelo iye yabonwa kwi-Yurophu ekuMbindi, e-United States, e-East Asia, e-Central England nase-Australia. Kuyo yonke le mimandla, ngaphandle kwe-Australia, bekukho amaxesha apholileyo kwii-70s, mhlawumbi ngenxa yeerosols.
Ukumangalisa, awucingi?
