Ngokuqinisekileyo sivile ukuba yintoni i-permafrost. Ngumaleko womhlaba ongumkhenkce ngokusisigxina kwaye inobude obuziimitha ezili-1.000 XNUMX kwezinye iindawo. Ifumaneka kanye emazantsi omhlaba kwimimandla yeArctic. Le permafrost yenziwa kwizigidi zeminyaka eyadlulayo xa kwakugqitywe iminyaka yeqhwa.
Ewe, okwangoku, Ngaphantsi kwempembelelo yabantu kunye nokufudumala kwehlabathi, le permafrost iyanyibilika. Uphando lwenziwe kwi-permafrost melting kwaye igqibe kwelokuba oku kungafikelela kwinqanaba lokuba kubangele ukutshintsha kwemozulu okubalekayo, ngaphandle kokuba sifumane ezinye iindlela zongenelelo.
Ingxaki ye-permafrost
I-Permafrost iyanyibilika ngenxa yobushushu behlabathi kwaye, ngaphandle kweengxaki ezibangelwa ziintlobo ezihlala kuyo kunye nayo yonke inkqubo enxulumene noko, ingxaki enkulu inayo kwiplanethi, kukuba iqulethe isixa esikhulu semethane esigciniweyo esinokukhutshelwa emoyeni ukuba ekugqibeleni inyibilika ngokupheleleyo.
Siyakhumbula ukuba igesi yemethane yirhasi yendalo ekwaziyo ukugcina ubushushu obuphindaphindaphindwe ngama-25 kune-carbon dioxide (CO2). Njengokuba umkhenkce unyibilika, imethane ihlala ikhutshelwa emoyeni kwaye, njengegesi yendlu eluhlaza, inyusa ubushushu behlabathi.
Asinakuyimisa le nkqubo, nangona kunjalo, singazama ukubamba imethane njengoko ikhutshwa, ukusukela oko kushishino lwegesi Unetekhnoloji yokwenza oku kwaye ujoyine umlo ochasene notshintsho lwemozulu.
Ngo-2014, izazinzulu zaqala ukufumanisa neekreyati ezingaqhelekanga kubume bomhlaba, ekubonakala ukuba zenzeke ngenxa yoqhushumbo. Kubonakala ngathi uxinzelelo ngaphakathi kweziduli luyakha de kube kukhutshwe iqabunga elikhulu lemethane ngamandla. Ukukhutshwa kwegesi yemethane kuneziphumo zehlabathi, kuba le gesi igcina kwaye inyuse iziphumo zotshintsho lwemozulu.
Yintoni ingxaki ngayo yonke lento? Ukuba nangona amashishini erhasi enetekhnoloji yokumisa oku kwaye abambe igesi yemethane, kuba ayinakho ukuthengiswa, abayityali. Isisombululo esinokubakho kukutshisa igesi ukuguqula i-methane ibe yi-CO2 egcina ubushushu obuncinci. Oku kunokuba ngcono kwindalo esingqongileyo kunokuvumela i-methane ibaleke. Nangona kunjalo, wonke lo msebenzi kuya kufuneka uxhaswe ngokupheleleyo ngoorhulumente.
