Arctic-ka ayaa dhalaalaya. Bishii Janaayo ee la soo dhaafay, barafkeeda baddu wuxuu diiwaan geliyay mid cusub oo abid hooseeya, sida ku cad sawirrada dayax gacmeedka. Iyadoo luminta 13,400 bilyan oo kilomitir oo laba jibbaaran, saynisyahannadu waxay saadaalinayaan in xilliga qaboobaha uu noqon doono midka ugu adag Arctic. iyo, wax kasta ka sarreeya, dadka deggan, sida orso cirifka, oo u baahan baraf si ay ugu soo dhowaadaan ugaarsadaan ugaarsigooda.
Si kastaba ha noqotee, heerkulka celceliska heerkulka adduunka ayaa sii kordhaya. Gobollada cirifka ayaa si gaar ah u nugul, maaddaama barafku ka tarjumayo falaaraha qorraxda, dib ugu celiya hareeraha. Laakiin waxaa imanaysa waqti ay daciifto oo dhalaasho, taasoo keenta in heerka badda kor u kaco.

Sawirkaan laga soo qaaday Xarunta Macluumaadka Barafka iyo Barafka Qaranka waxaad ku arkeysaa dusha sare ee barafku qabsaday bishii Janaayo ee sanadka 1981 - 2010, kuna calaamadeysan khad cas iyo midka uu ku fadhiyo sanadkan. Farqiga ayaa weyn. Laakiin, xaaladdu sidan ka duwanaan kari weyday. Sida laga soo xigtay NOAA, Waxay ahayd bishii saddexaad ee ugu kululayd Janaayo tixraac ahaan u qaadanaya isla muddadaas (1981-2010).

Celceliska heerkulka adduunka wuxuu istaagay 0,88ºC oo ka sarreeya celceliska 12ºC ee qarnigii la soo dhaafay, kii seddexaad ee ugu badnaa bishii Janaayo muddadii 1880-2017, heerkulka dusha badduna wuxuu ahaa 0,65ºC oo ka mid ah 15,8ºC celcelis ahaan qarnigii XNUMX-aad, kaas oo ahaa kan labaad ee ugu sareeya isla muddada tixraaca.
