<prompt> Fingqa isihloko: CNN Nakuba ingxenye enkulu ye-United States ibilokhu ivutha amakhaza kulobu busika, kuye kwaba nesinye isibonakaliso esikhathazayo sokushisa okufudumele enyakatho. Ngokwe - NASA, kubonakala sengathi iqhwa lasolwandle eliwela i - Arctic Ocean ebusika lincane kunawo wonke ake abhalwa kulo nyaka. Akukhona nje kuphela ukuthi ubukhulu balo nyaka obukhulu, obafinyelelwa ngo-February 25, bungobuncane kunabo bonke emlandweni wesathelayithi, kodwa futhi bungobokuqala. Ngaphandle kokukhula kancane kweqhwa - okungenzeka kodwa okungenzeka, ngokombiko wezindaba we - NASA - lokhu kubeka isibonelo esisha. Lokhu kuhlaziywa kusekelwe emininingwaneni evela kuyi-National Snow and Ice Data Center NSIDC yase-University of Colorado, eBoulder, esekelwa i-NASA. Iqhwa lasolwandle i-Arctic, amanzi olwandle ayiqhwa elintantayo phezu koLwandle i-Arctic nolwandle oluzungezile, lishintsha njalo. Uyanda ebusika, ngokuvamile ufinyelela esiqongweni sawo phakathi kokuphela kuka - February nokuqala kuka - April, bese uncipha lapho kushisa entwasahlobo nasehlobo ukuze ufinyelele esiqongweni sawo esiphansi ngo - September. Ngokwe-NSIDC, uma ububanzi obukhulu balo nyaka, obuhlanganisa amamayela-skwele ayizigidi ezingu-5,61, bafinyelelwa ngo-February 25, bafinyelelwa kusasele izinsuku ezingu-15 kunosuku oluvamile lwango-March 12, kusukela ngo-1981 kuya ku-2010. Kwakuke kwaba kanye kuphela ngaphambi kwalokho lapho isiqongo sifika ngaphambi kwesikhathi, ngosuku olulodwa nje ngo-1996. Ngokwe-NSIDC, inani eliphakeme elingamamayela-skwele ayizigidi ezingu-5.61 lingaphansi ngamamayela-skwele angu-50,000 kunesilinganiso esiphansi kakhulu sasebusika, esafinyelelwa ngo-2011. Ososayensi bebelokhu besebenzisa idatha yesathelayithi ukulandelela izinguquko eqhweni lasolwandle i-Arctic, indawo ebalulekile yezinyoni nezilwane ezincelisayo zasolwandle ezinjengezinyosi ezibandayo, izimpukane zasolwandle nama-walrus, iminyaka engaphezu kwamashumi amathathu. Ngokwe-National Oceanic and Atmospheric Administration, uTed Scambos, usosayensi oholayo we-NSIDC, ubeka irekhodi elilinganiselwe elilinganiselwe leqhwa lolwandle kulo nyaka phansi kweqhwa eliphansi ePacific kanye nokwehla okusheshayo kweqhwa olwandle lwaseBarents. Ngokwe-NOAA, imimoya enamandla yaseningizimu ekuqaleni kuka-March nayo yaba nomthelela. Yithi kuphela indawo yaseBaffin Bay namanzi azungeze iNewfoundland ayenomkhathi omningi kunokujwayelekile kulobu busika. Ososayensi bathi...  <response>: Ososayensi bathi iqhwa lasolwandle i-Arctic kubonakala sengathi selisezingeni eliphansi kakhulu kulobu busika. Ngaphandle kokukhula okusheshayo kokukhula kweqhwa lolwandle, inani eliphakeme lika-2015 lingamamayela-skwele ayizigidi ezingu-5,61.
