Ubushushu bomhlaba bunyuswa kukugcinwa kobushushu obenziwa ziigesi ze greenhouse xa imitha yelanga ichaphazela umphezulu womhlaba. Imitha yelanga inyusa amaqondo obushushu kwihlabathi liphela kwaye iyonyuswa ngeentsuku ezicacileyo.
Uphononongo olwenziwe zizazinzulu ezivela kwiZiko lezeNzululwazi ngezeNzululwazi kwiCSIC luphande ngeziphumo zokunyibilika kwamafu. Yintoni abanayo yokwenza omnye komnye?
Itha yoLwandlekazi iAntarctic
Ngokwenzululwazi baye baqhuba uphando, xa umkhenkce unyibilika ngenxa yamaqondo obushushu aphezulu ukhupha initrogen yomoya. Le nitrogen yemozulu ikhetha ukwakhiwa kwamafu. Uphononongo lufumanise amasuntswana avela kubomi obuncinci obuhlala kumkhenkce wolwandle kunye namanzi awungqongileyo.
Njengoko sisazi, ukunyibilika komkhenkce osemkhenkceni kwihlabathi liphela kukhawuleziswa sishushu kunye notshintsho lwemozulu. Lo mnyibiliko unokuthanda ukukhutshwa kwezinto ezinceda ukwenziwa kwamafu. Lo mahluko awuzange uthathelwe ngqalelo kulo naluphi na uphononongo lwemozulu epolar.
Ukuluqonda olu phononongo, kufuneka uhlalutye kwaye ujonge ukujonga jikelele kunye nokudibeneyo kuko konke ukuhlangana phakathi kolwandle, umkhenkce, umoya kunye nobomi. Oomatshini bemozulu bagqibelele kwaye baxhomekeke kulungelelwaniso oluzinzileyo nolungazinzanga.
Ezi datha zinokukhuthaza, kuba ngokwenziwa kwamafu okungcono, isixa semitha yelanga esiwela phezu komhlaba sinokwehla, ngaloo ndlela kuthoba ubushushu behlabathi. Ukongeza, ukwanda kwemvula kungaphelisa imbalela kwiindawo ezininzi zehlabathi kwaye ikhetha ukukhula kohlaza, ethi yona ikwenze imeko yamafu amatsha kwaye yenze imozulu engcono kunye nokufuma okwaneleyo.
