Heerkulka Greenland ee ugu kulul mudo 1,000 sano ah ayaa kiciyay Darren kale oo ku aadan khalalaasaha Cimilada aduunka sida ay tilmaameeyso Daraasad cusub oo daboolka laga qaaday arbacadan Dheeho.com
Daraasad cusub oo lagu sameeyay xudunta barafka ee Greenland ayaa tilmaamaysa in heerkulka kor u kacaya uu leeyahay ‘saxiixa cad ee kulaylka caalamiga ah’.
Xog cusub ayaa daaha ka qaaday in heerkulka Grønland uu yahay kii ugu kululaa ee soo mara muddo 1,000 sano ah, taas oo hoosta ka xariiqday saameynta sii kordheysa ee isbeddelka cimiladu ee bini’aadamku ay ku leeyihiin.
Daraasad lagu daabacay joornaalka sayniska ee Nature Arbacadii ayaa lagu ogaaday in heerkulku uu kor u kacay 1.5 darajo Celsius (2.7 darajo Fahrenheit) oo ka sarreeya celceliska qarniga 20-aad tan iyo 1995.
Associated Press àyaa warisay in Xogtu ay muujinayso xudunta barafka ee Greenland – oo laga soo qaaday muunado qoto dheer oo ku dhex jira barafyada iyo glaciers -uud u diiray ama kululaaday
“Waxaan sii wadeynaa [aragtida] heerkulka sare u kaca inta u dhaxaysa 1990-meeyadii iyo 2011,” ayay tiri qoraaga hogaanka u ah daraasadda Maria Hoerhold, oo ku takhasusay glaciologist ee Machadka Alfred Wegener ee Jarmalka. “Waxaan hadda haysanaa saxiix cad oo ku saabsan kulaylka caalamiga ah
Iyadoo isticmaalka shidaalka fosilku kaarboonka uu hawada ku sii daayo uu kulaylayo meeraha, saynisyahannadu waxay ka digeen in dawladuhu aanay weli samayn isbeddellada loo baahan yahay si looga hortago saamaynta ugu xun ee kulaylka adduunka.
Bishii Nofembar, warbixin ay soo saartay Qaramada Midoobay ayaa lagu ogaaday in qaar badan oo ka mid ah barafka caanka ah ee adduunka ay baabi’i karaan 2050 marka meeraha uu kululaado. In ka badan 18,600 glaciers oo uu ururku kormeero 50 ka goobood ee Dhaxalka Adduunka, qiyaastii saddex meelood meel meel ayaa la filayaa inay baaba’aan bartamaha qarniga.
Daraasad kale ayaa lagu ogaaday in saddex-meelood laba meel barafka adduunka la filayo inay baaba’aan sanadka 2100.
Koofiyadaha barafka ee Greenland, oo muujinaya macluumaad ku saabsan isbeddellada heerkulka muddada-dheer, waxay qaataan waqti ay ku falanqeeyaan. Xogta laga soo xigtay xudunta ayaa markii ugu dambeysay la cusbooneysiiyay 1995 waxaana hore loo soo jeediyay in Greenland aysan u kululayn sida ugu dhaqsaha badan gobolka Arctic intiisa kale
Saynisyahanka cimilada Martin Stendel oo ka tirsan machadka saadaasha hawada ee Danishka, oo aan ku lug lahayn cilmi-baarista Hoerhold ayaa sheegay in kala duwanaanshaha cimilada dabiiciga ah iyo is-bedelka ay sababto nidaamka cimilada ee mararka qaarkood loo yaqaan “Greenland blocking” ay hore u qariyeen khasaaraha ay dadku sababeen.
