Iplanethi iyafudumala, kodwa hayi kuyo yonke indawo ngokulinganayo. KwiArctic imeko imbi kakhulu. Ubungqina boku yingxelo epapashwe ngu-NOAA kwintlanganiso yonyaka ye-American Geophysical Union eyayibanjelwe eSan Francisco.
Bebonke oososayensi abangama-61 abavela kumazwe ali-11 bagqibezele lo msebenzi ubanzi, oboniswe ngemifanekiso kunye neemephu ezibonisa ubunyani beArctic.
Ubushushu eArctic: ukunyuka ngokukhawuleza okukhulu kwinqanaba
Umfanekiso - NOAA
KwiArctic ubushushu buyanda, kwaye kakhulu. Kumfanekiso ongentla ungayibona loo nto Kubekho ukunyuka okungaphezulu nje kwe-2 degreesNgelixa kwihlabathi liphela ubushushu obungu-1,31ºC. Iidigri ezimbini zisenokungavakali ngathi zininzi, kodwa kunokuba ngumahluko phakathi kokuma komhlaba kugqunywe ngokupheleleyo kwikhephu ixesha elininzi lonyaka, kuthathelwa ingqalelo indawo ekuyo iya kuba yeyona inengqiqo, okanye izityalo.
EGreenland ilahleko yomkhenkce ibetha kakhulu:
Umfanekiso - NOAA
Malunga ne-3000 gigatons zomkhenkce zilahlekile kulo nyaka. Umkhenkce onyibilikileyo othi, ewe, uphelele elwandle, ubangele ukuba umgangatho walo unyuke, ubeka emngciphekweni ubomi babo bonke abo bahlala kunxweme okanye kwiziqithi eziphantsi.
Ukwanda kokukhula kohlaza lwearctic
Umfanekiso - NOAA
Xa amaqondo obushushu enyuka kwaye umkhenkce unyibilika, kulindelwe ukuba kuya kubakho ukukhula ngakumbi kutyani. Kwi-Arctic, iimeko ezifanelekileyo ziyaqala ukuze izityalo zikhule, njengoko ubona kumfanekiso ongentla.
Inokuba intle, kodwa ayiqhelekanga. Njengokuba ubushushu busonyuka, zininzi izilwanyana ezineengxaki zokutyisa, ezinjengeebhere ezimhlophe, ezisemngciphekweni wokuphela.
