ESiberia, kuzoba wentaba ezimbili ezintsha omkhulu

Enhlabathini eqandisiwe eSiberia ezimbili ongaqondakali wentaba enkulu lesiRotuma. Le nqubo kwakulandelwa elikhulu kuqhuma beat futhi ezikhipha fu elinobuthi of intuthu nomlilo.

Ososayensi watimisela kuya endaweni emva reindeer umalusi endawo abika kuqhuma omkhulu, ikholomu lomlilo amafu amnyama intuthu e Russian Peninsula Yamal, ngokuvumelana laseSiberia Times.

Lapho simisa asemigodini

Kukholakala ukuthi omunye asemigodini kwakhiwa ngasekuqaleni kwalo nyaka, kanti eyesibili - ekuseni NgoJuni 28. Ukuqhuma kwesibili wawunamandla kangangokuba ngisho eqoshiwe iziteshi zokuzamazama komhlaba elise nasemadolobhaneni angomakhelwane kanye eduze lendawo gas field. I ububanzi we imbobo entsha amamitha ayisishiyagalombili kanye nokujula - hhayi ngaphansi kuka-20.

kwamiswa Lesi sigodi at ibanga amakhilomitha 35 kuya 40 enyakatho-ntshonalanga ye Seyakha (eSiberia). Lokhu ilandiswa wendawo reindeer umalusi Michael Okoteto. Budebuduze esikhundleni ukwakheka umalusi ekamu wentaba Yakova Vengo. Eduze kwenkamba wawusegunjini egqumeni, nokuthi laqhuma. Emoyeni landizela nezixhobo enkulu ezweni, kanye intuthu nomlilo. Ukuqhuma sentaba wanyamalala.

methane ukuqhuma

Banikezwe izincazelo bokuzibonela, ososayensi wendawo cabanga ngalesi sigameko njengoba ukuqhuma methane. Ezindaweni eziningi i-methane Arctic sibhajwe eyiqhwa. ukuncibilika Ezazimzungezile - ngokuvamile ngenxa izinqubo zemvelo, okuyinto zenziwe zaba zimbi kakhulu nge kwethonya indoda - lokhu kuvumela uhlelo igesi "ukuvuza" out. Uma i-methane lilondolozwe ngaphanzi komhlaba, kungabangela ingcindezi ukugcwala kwamanzi futhi ekugcineni kungaholela ukuqhuma. Kulokhu, akucaci ukuthi livelaphi emlilweni lapho, nakuba banikezwe flammability lula methane, akufanele kube kakhulu.

"Lokhu isiqephu sezwe uyisicaba ngokuphelele eminyakeni emibili edlule, kodwa-ke, ngo-2016, lapho ekhula, futhi ososayensi babone le ndawo ufa." - kusho uDkt Alexander Sokolov kusukela Russian Academy of Sciences. Nenets abantu bomdabu utshele abacwaningi ukuthi babona umlilo ebusika 2017, kodwa kungasho Januwari-Mashi noma Apreli. Ngamanye amazwi, i-methane phezulu kakhulu uma namanje embozwe yiqhwa.

Lezi ukuqhuma yayikade bhalisiwe e eSiberia nakwezinye izingxenye Arctic. Ucwaningo lwamuva, esanyatheliswa kumagazini i-Science, wasibonisa indlela esingayenza ngayo ingxenye olwandle Arctic iqandiswe asemigodini, okuyinto akhiwa emva ukuqhuma methane.

ebungozini

Emission methane kuyingozi hhayi kuphela ngenxa yokuba yinkimbinkimbi ukubikezela yayo futhi ukuqhuma. Kukholakala ukuthi ukukhulisa inani methane emkhathini has nethonya elinamandla ekhuluma ngokushintsha kwesimo sezulu. Ekugcineni, kuba Igesi ebamba ukushisa, efana CO _2.
