Nangona uphando luninzi oluqinisekisa ukuba ukufudumala kwehlabathi kuya kubakho imbalela Iba qatha ngakumbi, inde kwaye iphindaphindeka rhoqo, ngoku kukho nolunye uphando olungavumelani ncam nale ithiyori. Yeyona yayiqhutywa ngokudibeneyo yiDyunivesithi yaseCalifornia eIrvine nakwiDyunivesithi yaseWashington, neyapapashwa kwijenali yesayensi iProceedings of the National Academy of Sciences (PNAS).
Ngokwababhali, uxinzelelo oluphezulu lwekhabhon dayoksayidi luvumela izityalo ukuba zigcine amanzi amaninzi emhlabeni, ukuze zikwazi ukuziqhelanisa namaqondo aphezulu obushushu.
Kude kube ngoku, kuphela ngamaxabiso asesibhakabhakeni (iqondo lobushushu, ukufuma, imvula) ebeqwalaselwe ukuvavanya imbalela, njengePalmer yembalela yokumbalela. Ngale index, kuqikelelwa ukuba ngaphezulu kwe-70% iyakufumana imbalela ukuba ikhulu leminyaka ikhupha i-CO2 iphindaphindwe ngamaxesha amane angaphambi koshishino. Nangona kunjalo, ukuba ulwazi ngokusetyenziswa kwamanzi zizityalo lufakiwe, eli xabiso liwela 37%, ngoba?
Ikharbhon diokside ibalulekile kwizityalo. Ngaphandle kwayo, abakwazanga ukwenza ifotosinthesize kwaye babengenakukhula. Ukuyifunxa, zivula izakhiwo ezinamagqabi abizwa ngokuba yi-stomata, kodwa le yingxaki, kuba ivumela ukufuma kuphume. Nangona imeko itshintsha ukuba kuninzi i-CO2 ekhoyo kumoya ukusukela oko I-stomata ayidingi kuvulwa ixesha elide, kwaye ngenxa yoko, ukulahleka kwamanzi kuncinci.
Okwangoku, ukuba imbalela yenzeka ngamaxesha ashushu, ziyabulala. Izityalo ziba buthathaka, kwaye ngokwenza njalo izinambuzane zibulala ngeentsuku ezimbalwa kakhulu. Ke, nangona incinci kakhulu imbalela, inokuba neziphumo ezibi.
