Umkhenkce wolwandle iArctic uhlasela irekhodi eliphantsi ngoJanuwari

Arctic

IArctic iyanyibilika. NgoJanuwari ophelileyo, umkhenkce waso waselwandle ubhalise indawo ephantsi ngalo lonke ixesha, ngokwemifanekiso yesathelayithi. Ngokulahleka kwe-13,400 yeebhiliyoni zeekhilomitha, izazinzulu ziqikelela ukuba obu busika buza kuba bobona bunzima kwiArctic kwaye, ngaphezu kwako konke, kubemi bayo, njengebhere emhlophe, abafuna umkhenkce ukuze bakwazi ukusondela nokuzingela amaxhoba abo.

Nangona kunjalo, iqondo lobushushu lehlabathi liqhubeka nokunyuka. Imimandla esemajukujukwini isesichengeni ngakumbi, kuba ikhephu libonisa imitha yelanga, lize liyibuyisele emajukujukwini. Kodwa kuye kufike ixesha apho iyancipha kwaye inyibilike, ibangele ukuba ulwandle lukhuphuke.

Umkhenkce wolwandle lweArctic

Kulo mfanekiso unokubona indawo apho umkhenkce wawuhlala khona ngenyanga kaJanuwari wonyaka ka-1981-2010 ophawulwe ngomgca obomvu. Umfanekiso-iZiko leDatha leSiqhwa kunye noMkhenkce

Kulo mfanekiso usuka kwiZiko leSizwe leKhephu kunye neQhwa ungawubona umphezulu owawuhlala umkhenkce ngenyanga kaJanuwari kwisithuba sika-1981-2010, ephawulwe ngomgca obomvu nalowo ukulo nyaka. Umahluko mkhulu. Kodwa, imeko ayinokwahluka. Ngokuka-NOAA, Ibe yinyanga yesithathu efudumeleyo ngoJanuwari ithatha njengesalathiso kwangexesha elifanayo (1981-2010).

Ukungaqheleki kobushushu ngenyanga kaJanuwari 2017

Ukungahambi kakuhle kwamaqondo obushushu kumhlaba nakulwandle ngoJanuwari 2017. Umfanekiso-NOAA

Iqondo lobushushu lehlabathi belimi kwi-0,88ºC ngaphezulu kwe-12ºC yomndilili wenkulungwane ephelileyo, okwesithathu okuphezulu ngoJanuwari kwithuba le-1880-2017, kwaye iqondo lobushushu kumphezulu wolwandle yayingu-0,65ºC we-15,8ºC womndilili wenkulungwane yama-XNUMX, eyayiyindawo yesibini ephezulu ngexesha elifanayo.

Ipesenti yokulahleka komkhenkce wolwandle i-Arctic ngeenyanga zika-Okthobha ukuya kuFebruwari ukusukela ngo-1981.
