Nangona inokuba nomdla, Umkhenkce waseArctic uyaqhubeka unyibilika ebusika, njengoko kutyhilwe yidatha yakutshanje kaJanuwari evela kwiZiko leSizwe leSiqhwa kunye neQhwa (i-NSIC kwisifinyezo sayo ngesiNgesi). Kwinyanga leyo yaphela nge-13,06 yezigidi zeekhilomitha zomkhenkce, i-1,36 yezigidi zeekhilomitha ngaphantsi kwexesha lesalathiso ukusuka kwi-2 ukuya kwi-1981.
Amaqondo obushushu kule nxalenye yehlabathi ashushu kakhulu ukuba umkhenkce ubambe, ke IArctic kulindeleke ukuba ishiywe ngaphandle kwekhephu layo kwikamva.
Ulwandle lweArctic kurekhodwe iqondo lobushushu ubuncinci i-3 degrees Celsius ngaphezulu komndilili. Kulwandle lwaseKara naseBarents olu lwando lwaya kutsho kwi-9ºC. Kwicala lePasifiki, ithemometha ifunde malunga ne-5ºC ngaphezulu komndilili; kwelinye icala, eSiberia iqondo lobushushu lalifikelela kwi-4ºC ngaphantsi kunesiqhelo.
Olu tshintsho belusisiphumo somoya ojikelezayo ohambisa umoya ovela emazantsi, ofudumeleyo, kunye nokukhupha ubushushu buye kwiatmosfera kwiindawo ezinamanzi avulekileyo. Ngapha koko, uxinzelelo lomphakamo wolwandle lwaluphezulu kunesiqhelo kumbindi weArctic, ukuze umoya oshushu osuka e-Eurasia udluliselwe kula mmandla weArctic.

Ukuba akukho nto itshintshayo Umndilili weqondo lobushushu kulindeleke ukuba lenyuke nge-4-5 degrees ngekhulu leminyaka, eyayiza kumela kabini into ekulindeleke ukuba inyuke kumantla ehlabathi. Ngokubhekisele kumkhenkce, inokuphantse inyamalale ngokupheleleyo, kungabikho ngaphantsi kwesigidi esinye seekhilomitha ezishiyekileyo ihlobo ngalinye ukusuka kwiminyaka ye-1, ngokuqinisekileyo kwaye ngelishwa oko kuthetha ukuphela kweebhere ezimhlophe.
Ngolwazi oluthe kratya, sicebisa ukuba sikwenze cofa apha.
