Iziphumo zeentaba-mlilo zeAntarctic ziqhuma

INtaba iTakahen yaseAntarctica

Intaba takahe

I-Antarctica lelona lizwekazi lisemazantsi eMhlabeni, liguqula ubuso balo libe yingubo enomkhenkce. Nangona ezinye iintaba-mlilo bezisaziwa iminyaka, idatha entsha yesathelayithi ixele ukuba phantsi kwaloo mkhenkce kukho malunga ne-100 ngaphezulu ebingaziwa. A kufunda epapashwe kwi-United States National Academy of Sciences ichaze into ebalulekileyo yokuba yenzeke kwiminyaka engama-18.000 XNUMX eyadlulayo. Izazinzulu zePaleoclimatic ziphande ezinye Ukuqhuma okukhulu kweNtaba iTakahe, okuphelise ixesha lokugqibela lomkhenkce kwakukho.

Ukusuka kwiirekhodi ezifunyenwe ngumkhenkce, ugqabhuko-dubulo wafunyanwa utyebile kwi-halogen kwaye watya i-ozone eyoneleyo ukuze ngokuqinisekileyo wenze umngxunya omkhulu kumaleko we-ozone. Kulapho kwaqala khona ukwanda okukhawulezayo, okwalathe kwiNtaba iTakahe ngokwalo njengeziko elinoxanduva. Inkqubo ye- Iziphumo ezibi zafunyanwa ne-2.800km ukusuka kwindawo yokuqhuma, kunye neempembelelo zayo zafikelela kwi-subtropics.

Yintoni esinokuyilindela ukuba kunokuqhambuka intaba-mlilo engaphezulu kwesinye?

Le meko iya kuba mandundu kakhulu. Kwaye nangona kungenakulindeleka ukuba ukuqhuma okungaphezulu kwesinye kwenzeke ngaxeshanye, ayisosiganeko esingenakwenzeka. Kwisandle esinye sineentaba-mlilo ezingaphezulu, NjengeNtaba iTakahe, kwaye ezinye ezingaphakathi ngakumbi zaziwa ngokuba ziyasebenza kodwa azidubuli. Kule meko, ekunokwenzeka ukuba kuqhume ixesha elizayo, ukuze ibangele ukungazinzi kuya kufuneka benze ngamanani amakhulu kunye nobundlobongela.

Into esinokuyifumana iya kuba ukunyibilika ngokukhawuleza komphezulu. Ukuba kuqhambuka udlame, kuyakubakho umngcipheko wokuqhuma kweentaba-mlilo ezintsha. I-thaw, esele ithathele ingqalelo ngakumbi, iya kuba njalo anyuse amanqanaba olwandle. Ipaseji yolwandlekazi, eyisekethe yolwandle yolwandle ehambisa amaqondo obushushu, iya kutshintshwa, ichaphazele indawo enkulu yezilwanyana zaselwandle. Njengoko iAntarctica ingabususi ubushushu obungaka, Ingonyusa kakhulu iqondo lobushushu kwihlabathi liphela, ngakumbi kumazantsi e-hemisphere. Iya kuba yile Iziphumo zeDomino Into eyoyikwayo inokwenzeka, iluphu yengxelo, kokunyibilika okungakumbi, kokukhona kunokwenzeka ezinye iintaba-mlilo ziqhume. Elinye lamatyala ambalwa apho iintaba-mlilo, ngaphandle kokufikelela kudidi lwee-supervolcano, zinokuphazamisa ngesiquphe imeko yemozulu.
