Soo koob maqaalka:  Meel yar oo kulul oo ku taal Koonfurta Galbeed ee Maraykanka ayaa mas'uul ka ah soo saarista qiiqa ugu badan ee methane ee lagu arko Maraykanka - waana mowduuca baaritaan weyn oo cusub si loo ogaado sababta. Goobta kulul, oo u dhow isgoyska Afarta gees ee Arizona, Colorado, New Mexico iyo Utah, waxay dabooshaa oo keliya qiyaastii 2,500 mayl laba jibbaaran (6,500 kiiloomitir oo laba jibbaaran), ama kala bar cabirka Connecticut. Khariidada NASA ee dhowaan la sameeyay ayaa muujineysa in ay soo saartay in ka badan seddex jeer qiyaasta caadiga ah ee dhulka ku saleysan - cilmi baarayaashuna waxay yiraahdaan ma garanayaan sababta.. Hoos u rog fiidiyowga. Aagga Afarta gees (casaan) waa goobta ugu weyn ee Mareykanka ee kuleylka methane ee khariidadan oo muujineysa inta ay le'eg tahay qaddarka u dhexeeya heerarka celceliska ee 2003-2009 (midabada mugdiga ah ayaa ka hooseeya celceliska; midabada iftiinka ah ayaa ka sarreeya). Goobta kuleylka ah, ee ku dhow isgoyska Afarta gees ee Arizona, Colorado, New Mexico iyo Utah, waxay dabooshaa kaliya 2,500 oo mayl oo isku wareeg ah. Methane-ku wuxuu si aad ah ugu habboon yahay inuu kuleylka ku qabsado jawiga. Sida kaarboon dioxide, waxay gacan ka geysaneysaa kulaylka caalamka. Si loo xisaabiyo heerka qiiqa ee loo baahan yahay si loo soo saaro heerka methane ee hawada lagu arkay, qorayaashu waxay sameeyeen jilitaanka gobolka oo leh xallinta sare iyadoo la adeegsanayo qaab gaadiid kiimiko ah, kaas oo u ekaysiinaya sida cimiladu u dhaqaaqdo oo u bedesho isku-darka kiimikada hawada. Cilmi baadhayaal ka kala socda hay'ado kala duwan ayaa hadda ku sugan gobolka Four Corners ee Koonfurta Galbeed ee Maraykanka iyagoo wata qalab hawada iyo dhulka ku saleysan, ujeedadoodu tahay inay soo bandhigaan sababaha'meel kulul' oo methane ah oo qarsoodi ah oo laga helay bannaanka. 'Iyada oo dhammaan khayraadka dhulka iyo hawada ee kooxaha kaladuwan ay keenaan gobolka, waxaan leenahay fursad gaar ah oo aan si cad u xallin karno qarsoodiga Afarta gees,' ayuu yiri Christian Frankenberg, oo ah saynisyahan ka tirsan Shaybaadhka Qalabka Qalabka ee NASA, Pasadena, California, oo hogaaminaya qaybta NASA ee dadaalka. Baarayaasha kale waxay ka yimaadeen Machadka Iskaashiga ee Cilmi-baarista ee Sayniska Deegaanka (CIRES) ee Boulder, Colorado; Qaranka Oceanic iyo...
Meel yar oo'kulul'oo mas'uul ka ah soo saarida qanjidhada ugu badan ee gaaska methane ee lagu arko Maraykanka. Aagga u dhow isgoyska Afarta gees ee Arizona, Colorado, New Mexico iyo Utah wuxuu daboolayaa 2,500 mayl oo laba jibbaaran. Goobta kulul waxay ka horraysaa burburka baaxadda leh ee aagga.
