Uthuli lwenyanga lukhusela kwimitha yelanga

Uthuli lwenyanga olusasazwa emajukujukwini lunokwenza ukhuseleko olusebenzayo kuMhlaba ekukhanyeni kwelanga onegalelo ekulweni nokutshintsha kwemozulu, ngokutsho kweqela labaphandi elibone kuphononongo olupapashwe ngoLwesithathu, liphephancwadi iPLOS Climate.

Ezi nzululwazi zisekelwe eUnited States zabhala ukuba “uthuli oluninzi” olukhoyo phakathi koMhlaba neLanga “lunokunciphisa umlinganiselo wokukhanya kwelanga ofunyanwa sisijikelezi-langa.

Umbono kukudala into efana nomqobo ovumela ukuba inxalenye yemitha ivalwe ukunciphisa utshintsho lwemozulu.

Abaphandi balinganisa inani leemeko, kubandakanywa ukuchithwa kwamasuntswana othuli ukusuka kwiqonga lendawo elibekwe kwelinye lamanqaku eLagrangian, apho amandla okuxhuzula phakathi koMhlaba kunye neLanga alungelelaniswe.

Olu thuli lufanele ke ngoko lube ngumqobo okhuselayo kodwa lunokusasazeka lula, lufuna ukuphinda kugalelwe uthuli rhoqo emva kweentsuku ezimbalwa.

Izazinzulu ziphinde zacebisa esinye isicombululo abasibona njengesithembisayo, ekukusasazwa kothuli lwenyanga lusuka ngqo phezulu enyangeni lusiya elangeni kusetyenziswa imijukujelwa.

Kwaye bachaza ukuba bachonge "iindlela ezivumela uthuli ukuba lube nomthunzi iintsuku." Bachaza ukuba iingenelo zale ndlela kukuba lo mthombo ubuninzi kwiNyanga, kwaye ifuna ukusetyenziswa kwamandla okuncinci kunokuqaliswa okuvela eMhlabeni.

Nangona kunjalo, bavuma ukuba lo mbandela okwangoku ukhawulelwe ekuhloleni ukuba kunokwenzeka ukwamkela esi sisombululo kwithiyori, kwaye akazange afikelele kwinqanaba lokufunda ukuba kunokwenzeka njani le teknoloji.

"Asizizo iingcali zokutshintsha kwemozulu okanye ubunjineli be-aerospace," utshilo uBen Bromley, unjingalwazi wefiziksi kunye neenkwenkwezi kwiYunivesithi yase-Utah, ongumbhali okhokelayo wokufunda.

Kutshanje, kuye kwakho iiprojekthi ezininzi zegeoengineering ezijolise ekunciphiseni ukufudumala kwemozulu okubangela ukuba umhlaba ubandezeleke ngokuthe ngcembe, kodwa ezinye zazo ziyintsomi nje yenzululwazi.

Phakathi kwezona projekthi zibalaseleyo kukongezwa ngabom kwamasuntswana anqunyanyiswayo kwistratosphere ukuze kuthintelwe inxalenye yemitha yelanga.

Kodwa iZizwe Ezimanyeneyo ziye zalumkisa ngelokuba ubugcisa obunjalo bunokuba nemiphumo emibi kucwecwe lweozone. Ukusebenzisa uthuli lwenyanga, kude neatmosfera yoMhlaba, kuya kuyinqanda le ngxaki.

Nangona kunjalo, uluntu lwezenzululwazi lujongane nophononongo, olupapashwe ngoLwesithathu, kunye nokubekwa okuthile.

Eqinisekisa ukuba uthuli lwenyanga lunokusetyenziswa ngokwenene njengesambrela, uStuart Hazeldine weYunivesithi yase-Edinburgh wagxininisa imfuneko yokukhetha “imilo yesuntswana elungileyo, ubungakanani obufanelekileyo kunye kanye nendawo efanelekileyo”, okungelula.

Ngokuphathelele uJoanna Hay weYunivesithi “yeKholeji yase-Imperial yaseLondon,” wabona ukuba “eyona ngxaki iphambili sisindululo sokuba iiprojekthi ezilolu hlobo ziya kusombulula ingxaki yemozulu, ngelixa enika abangcolisi isizathu sokungenzi” ukujongana nayo.
