Iintaka zolwandle zinceda ekunciphiseni ubushushu beArctic, kwaye bayenza ngendlela enomdla kakhulu ngokophando olupapashwe kwijenali yesayensi yeNdalo.
Kule nxalenye yehlabathi, ukunyuka kwamaqondo obushushu kubangela iingxaki ezinkulu, nangona ngaphandle kwezi zilwanyana, imeko ibiya kuba mbi kakhulu.
UGuano, umlingane ongalindelekanga weArctic
Kunjalo. IGuano yeyona icothisa ukufudumala. Izazinzulu ziye zafumanisa ukuba ukuya kwi-400.000 yeetoni zeguyano zibekwa emhlabeni ngexesha lokufuduka kunye nokuhlala kwezi zilwanyana zintle. Ayisetyenziselwa ukuchumisa umhlaba kunye nezityalo ezinokukhula kuwo, kodwa kubangela ukwakheka kwamafu okuphezulu kwe-albedo, Evelisa ukupholisa okuphakathi kwe-0,5 watts kwimitha nganye nganye.
Ayisiyonto ingako, kwaye ayenzeli ukufudumala kwe-polar, kodwa oku kufunyanwa kwixesha elifutshane okanye eliphakathi kunokubangela ukuba kuphuhliswe isicwangciso esisebenzayo sokukhusela iArctic zotshintsho olukhawulezileyo olwenzekayo kwimozulu yehlabathi ingakumbi kwiipali.
Amasuntswana e-ammonia aphuma kwi-guano afaka isandla ekwakhiweni kwamafu, abonisa ukukhanya kwelanga, awubuyisele endaweni.
Amasuntswana e-ammonia, akhoyo kwi-guano, ngokuqinisekileyo ajikeleze kwiikholoni, kodwa ngenxa yokuba incinci kakhulu, ingabonakali kwiso lomntu, umoya uyayithwala, uyisasaze kuwo wonke ummandla we-Arctic.. Ngale ndlela, iimeko ezifanelekileyo zinikezelwa ukwenziwa kwamafu azakubonisa ukukhanya kwelanga, oko ke kuthintela amaqondo obushushu ukuba anganyuki kwaye umhlaba nolwandle zingafudumezi.
Ngokuqinisekileyo kukufumana okunomdla kakhulu, awucingi?
