Siphila kwihlabathi apho ukonyuka okuqhubekayo kwamaqondo obushushu kubangela iingxaki ezininzi emhlabeni, njengokunyibilika kunye nokunyuka okulandelayo kumgangatho wolwandle, imbalela ekhula ngamandla, iinkanyamba ezitshabalalisayo, kodwa sihlala silibale malunga ozone.

Olu luhlu, oluqala ukusuka kwi-15km ukuya kwi-50km ukuphakama, kubaluleke kakhulu ukugcina impilo. Ngoku isifundo siveze ukuba ukufudumala kwesidanga esithathu kunokusongela.

Ukunyamalala kocingo lwe-ozone, okanye nokuncitshiswa kwayo, inokunyusa inani lezehlo zomhlaza. Oku, ekunokubonakala ngathi kukude ekuqaleni, kusenokungabikho ngoku. Ukwanda kwamaqondo obushushu kuyinyani yokwenyani emhlabeni wonke: sibe ngaphezulu kweenyanga ezingama-300 ezilandelelanayo apho amaxabiso abhaliswe ngaphezulu kwesiqhelo.

Ngongcoliseko, ukugawulwa kwamahlathi, kunye nokusetyenziswa kweemveliso eziyityhefu kwindalo esingqongileyo, abantu bazibeka esichengeni kunye nazo zonke ezinye iintlobo zobomi kulo mhlaba.

Ngokophando, ebelupapashwe kwijenali yeNdalo yoNxibelelwano, Kubaluleke kakhulu ukuba kuthathwe amanyathelo ehlabathi ukulawula imveliso yemethane, ingxaki enkulu kwindalo eYurophu.

Umngxunya weozone

Ababhali bokufunda, kubandakanya no-Audrey Fortems-Cheiney weziko laseFrance i-Institut uPierre Simon Laplace, basebenzise imodeli yokuhambisa imichiza ukujonga okuza kwenzeka kwi-ozone ukuba amaqondo obushushu ama-2 okanye ama-3 degrees aphezulu afikelelwe kwiimeko ezahlukeneyo nge izinto ezahlukeneyo zokuthomalalisa.

Ke, babenako ukuqaphela ukuba kwimeko ngaphandle kokunciphisa ukukhutshwa kwegesi, ngokufudumeza kwe-3 ofC phakathi ko-2040 no-2069, Amanqanaba e-ozone ayephezulu nge-8%. Ukuba iba yinyani, ukuncitshiswa okufezekisiweyo ngokuphunyezwa kwemimiselo yokukhutshwa kwe-ozone kuya kugqitha; Okanye ubeke enye indlela: umngxunya oselalini ye-ozone, ebekwe malunga ne-15km ukusuka e-Antarctica, unokukhula ube mkhulu.

    Busuku benzolo,

    Mhlawumbi ndiphosakele, kodwa ndicinga ukuba isifundo osidibanisayo sibhekisa kwi-ozone yetropop, hayi i-ozone (stratospheric) kwaye ayitsho ukuba izokwehla, kodwa inyuke, into embi kuba inetyhefu. Ngapha koko, kumhlathi weli nqaku ithi "amanqanaba e-ozone aya kunyuka nge-8%, enokwandisa umngxunya ngaphezulu kwe-Antarctica." Ukuba amanqanaba e-ozone anyuka, kutheni umngxuma unyuka?

    Ndinyanzelisa, mhlawumbi ndenza impazamo, kwimeko apho ndixolela ukungazi kwam. Imibuliso.
