Oku kuthethwe liqela lehlabathi elenziwe ngabaphandi abathandathu abavela eNorway, e-United Kingdom naseSweden, abathe bapapasha uphononongo kwiphephancwadi lezenzululwazi 'iNguqulelo yemozulu. Ukuze sikwazi ukufumana uluvo lwenani le-permafrost eya kulahleka ngenqanaba ngalinye lokufudumala, kufuneka sazi ukuba yindawo enkulu kuneIndiya.
I-Permafrost, loo mqolo womhlaba uhlala unqabile iminyaka emibini ubuncinci, egubungela phantse i-15 yezigidi zeekhilomitha zomhlaba, Iya isiba buthathaka njengesiphumo sokufudumala kwehlabathi.
Izixa ezikhulu zekhabhoni zigcinwa kwi-permafrost, eyingxaki enkulu namhlanje. Njengokuba isijikelezi-langa sifudumala, eli qweqwe lomkhenkce liyanyibilika, lenze into ephilayo ebambeke kuyo iqale ukubola. Ngokwenza njalo, Ziyakhutshwa iigesi eziluhlaza ezifana nekhabhon diokside kunye nemethane, zimbini iigesi eziphambili ezibangela ukwanda kwamaqondo obushushu.
Ukufikelela kweso sigqibo, Abaphandi bavavanye ukuba eli qheke lomkhenkce litshintsha njani kubume behlabathi kunye nobudlelwane bayo namaqondo obushushu. Baye baphanda into enokwenzeka ukuba amaqondo obushushu ayonyuka kwaye, besebenzisa le datha, benze imephu yokuhambisa amanzi ngobuninzi. Baye ke bakwazi ukubala isixa se-permafrost esiya kulahleka ukuba ubushushu behlabathi bunokuthintelwa ukuba bunyuke ngaphezu kwama-2 degrees.
Enkosi kule kufunda Oososayensi bakwazi ukufumanisa ukuba i-permafrost iyakwazi ukuthintela ukufudumala kwehlabathi kunokuba bekucingwa ngaphambili: ukuzinzisa imozulu ku-2ºC ngaphezulu kwamanqanaba angaphambi kwemizi-mveliso kungathetha ukunyibilika ngaphezulu kwe-40% yemimandla ekhoyo ngoku. Ukuba oku kunokwenzeka, abantu abazizigidi ezingama-35 abahlala kwezi ngingqi kuya kufuneka bathathe amanye amanyathelo, njengoko iindlela kunye nezakhiwo zinokuwa.
