Uthuli lwenyanga luvikela emisebeni yelanga

Uthuli lwenyanga olusabalele emkhathini lungase lube isivikelo esisebenzayo soMhlaba ekukhanyeni kwelanga esinomthelela ekulweni nokushintsha kwesimo sezulu, ngokwalokho okwabonwa ithimba labacwaningi ocwaningweni olushicilelwe, ngoLwesithathu, ngumagazini i-PLOS Climate.

Laba sosayensi abazinze e-US babhala ukuthi “uthuli oluningi” olukhona phakathi koMhlaba neLanga “lunganciphisa inani lokukhanya kwelanga elitholwa yiplanethi.

Umqondo uwukwenza into efana nomgoqo ovumela ingxenye yemisebe ukuthi ivinjwe ukuze kuncishiswe ukushintsha kwesimo sezulu.

Abacwaningi balingisa izimo eziningi, okuhlanganisa nokusatshalaliswa kwezinhlayiya zothuli ezivela endaweni yesikhala etholakala kwelinye lamaphoyinti e-Lagrangian, lapho amandla adonsela phansi phakathi koMhlaba neLanga alinganisela khona.

Ngakho-ke lolu thuli kufanele lube umgoqo ovikelayo kodwa lungahlakazeka kalula, ludinge ukuphinda kufakwe uthuli njalo ezinsukwini ezimbalwa.

Ososayensi baphinde bahlongoza elinye ikhambi abalibona lithembisa, eliwukusakazeka kothuli lwenyanga lusuka ngqo phezu kwenyanga lubheke elangeni ngamarokhethi.

Futhi bachaza ukuthi babeyibonile “imizila evumela uthuli ukuba lube nomthunzi izinsuku eziningi.” Bachaza ukuthi izinzuzo zale ndlela ukuthi le nsiza igcwele eNyangeni, futhi idinga ukusetshenziswa kwamandla okuncane kunokwethulwa eMhlabeni.

Kodwa-ke, bavumile ukuthi lolu daba okwamanje lukhawulelwe ekuhloleni ukuthi kungenzeka yini ukwamukela lesi sixazululo ngombono, futhi abazange bafinyelele izinga lokufunda ukuthi kungenzeka yini lobu buchwepheshe.

“Asibona ongoti kwezokushintsha kwesimo sezulu noma kwezobunjiniyela be-aerospace,” kusho uBen Bromley, uprofesa wefiziksi nesayensi yezinkanyezi eNyuvesi yase-Utah, ongumbhali oholayo walolu cwaningo.

Muva nje, kuye kwaba nemiklamo eminingi ye-geoengineering ehloselwe ukukhawulela ukushisa kwesimo sezulu okuhlupha umhlaba kancane kancane, kodwa eminye yayo iyinganekwane yesayensi.

Phakathi kwezinto ezivelele kakhulu zale miklamo ukufakwa ngamabomu kwezinhlayiya ezimisiwe kuyi-stratosphere ukuze kuvinjwe ingxenye yemisebe yelanga.

Kodwa iZizwe Ezihlangene ziye zaxwayisa ngokuthi ubuchwepheshe obunjalo bungaba nemiphumela emibi ongqimbeni lwe-ozone. Ukusebenzisa uthuli lwenyanga, kude nomkhathi woMhlaba, kungagwema le nkinga.

Kodwa-ke, umphakathi wesayensi ubhekane nalolu cwaningo, olushicilelwe ngoLwesithathu, ngokubhuka okuthile.

Eqinisekisa ukuthi uthuli lwenyanga lungasetshenziswa ngempela njengesambulela, uStuart Hazeldine waseNyuvesi yase-Edinburgh wagcizelela isidingo sokukhetha “umumo wezinhlayiyana ofanele, usayizi ofanele kanye nendawo efanele nje”, okungelula.

Ngokuqondene noJoanna Hay waseNyuvesi “ye-Imperial College London,” wabona ukuthi “inkinga enkulu isiphakamiso sokuthi amaphrojekthi alolu hlobo azoxazulula inkinga yesimo sezulu, kuyilapho enikeza abangcolisi izaba zokuthi bangathathi isinyathelo” sokubhekana naso.
