MuSiberia, pakanga pane maviri matsva makuru matsva

Panyika yechando yeSiberia, zviviri zvisinganzwisisiki zvakakonzerwa nemakona mave achangobva kuonekwa. Iyi nzira yaifambidzana nekumhanya kukuru uye kubvuta utsi nemoto.

Masayendisiti akasarudza kuenda kunharaunda mushure mokunge muchengeti wemhuka wekunze achizivisa kuputika kukuru, chitubu chemoto nemakore madema eutsi paRussian peninsula Yamal, yeSiberia Times yakashuma.

Apo mashizha akaumbwa

Zvinotendwa kuti chimwe chezvikwata zvakaumbwa pakutanga kwegore rino, uye yechipiri - mangwanani aJune 28. Kuputika kwechipiri kwaive kwakasimba zvikuru zvokuti kwakatonyorwa zvakare nezvivako zvekusimudzira zviri munzvimbo dzakapoteredza uye pedyo nenzvimbo yegasi yemunharaunda. Iyo yakareba yehitsheni itsva inenge mamita masere, uye yakadzika inenge mamita makumi maviri.

Nzvimbo yakaumbwa iri kure nemakiromita makumi matatu nemashanu kusvika kumaodzanyemba kwekumaodzanyemba kweSeyahi (Siberia). Izvi zvakataurirwa nemudzimai wezvipfuwo zvemukati Mikhail Okoteto. Hasi kure nenzvimbo yekanyasi yekugadzirisa ndiyo musasa wemudziki wemhuka wezvipfuwo James Wengo. Pedyo nemusasa waiva gomo, uye ndiye iye akaputika. Mumhepo maiva nemiti yakawanda yevhu, uyewo utsi nemoto. Somugumisiro wekuputika, gomo racho rakanyangarika.

Kuwedzera kwemethane

Zvichipiwa zvinotsanangurwa nevanoona, veasayendisiti vemo vanoona chiitiko ichi sekuputika kwemethane. Munzvimbo dzakawanda dzeArctic, methane yakanga yakabatwa muhutachiona. Iyo inonyunguduka - kazhinji inokonzerwa nehutachiona hwezvinhu zvakasimbiswa nehutungamiri hwevanhu - inobvumira gesi iyi kuti "inononoka" kunze. Kana methane inowedzera pasi pevhu, inogona kukonzera kugadzirwa kwekumanikidzwa uye pakupedzisira inotungamirira mukuputika. Muchiitiko ichi, hazvisi pachena kuti moto wakabva kupi, kunyange zvazvo uchifunga nezvekuvhenekera kwemethane, haifaniri kuva yakawanda.

"Iyi yenyika yakanga yakanyarara chaizvo makore maviri akapfuura, asi muna 2016 yakakura uye masayendisiti akaona kutyisa panzvimbo ino," anodaro Dr. Alexander Sokolov weRussia Academy of Sciences. Nenets vagari vemo vanoudza masayendisiti kuti vakaona moto munguva yechando ye 2017, asi izvi zvinogona kureva January-March kana kunyange April. Mune mamwe mazwi, methane yakaputika apo yakanga ichiri kuchando.

Kuburikidza kwakafanana kwakambove kwakanyorwa kuSiberia uye dzimwe nzvimbo dzeArtictic. Migumisiro yekuongorora kwechangobva kuitika, yakabudiswa mumagazini inoScience, yakaratidza kuti zvikamu zvegungwa reActictic zvakagadzika sei mumakona akaumbwa mushure mokuputika kwemethane.

Njodzi dzinogona kuitika

Kusunungurwa kwemethane kune ngozi, kwete nekuda kwekuoma kwehuwandu hwekufanotaura uye kuputika. Zvinotendwa kuti kuwedzerwa kwehuwandu hwemethane mumhepo inoita zvinoshamisa pakuchinja kwemamiriro ekunze. Mushure mezvose, iri gasi rinopisa, seC CO ₂ .
