<prompt> Fingqa isihloko: Lobu busika bube yisikhathi esihlukanise iMelika yaba izingxenye ezimbili. Lelibalazwe lesimo sezulu elihlaba umxhwele libonisa indlela labo abasentshonalanga yezwe abajabulela ngayo enye yezinyanga zikaFebruary ezifudumele kunazo zonke emlandweni, kuyilapho labo abasempumalanga babhekana neqhwa eliningi namazinga okushisa ayebanda kakhulu. Ngokwe-Earth Observatory ye-NASA, abanye ochwepheshe baye bathi lokhu kwehlukahluka okukhulu kwamazinga okushisa kubangelwa ukufudumala kwembulunga yonke nokuncibilika kweqhwa lolwandle e-Arctic. Isithombe sesathelayithi esenziwe i - NASA siqopha izinga lokushisa komhlaba. Izindawo ezinezimo ezingaphansi kwesilinganiso zinombala oluhlaza okwesibhakabhaka, ezijwayelekile zibonakala zimhlophe kanti lezo ezibomvu zazifudumele kunesilinganiso. Lemephu yenziwe kusetshenziswa idatha yesathelayithi ye-Terra ye-NASA futhi ibonisa ukuthi amazinga okushisa kuloFebhuwari aqhathaniswa nalawo eminyaka eyishumi edlule.. Isathelayithi yabala izinga lokushisa komhlaba futhi ibalazwe libonisa ukuhlukana okucacile maphakathi nezwe. Izindawo ezaba nezimo ezipholile kunezinga elijwayelekile zibhalwe ngombala oluhlaza okwesibhakabhaka, ezijwayelekile zibukeka zimhlophe, kanti lezo ezibomvu zazifudumele kunezinga elijwayelekile. Amazinga okushisa enyuka cishe ngo - 10 degrees ngaphezu kwesilinganiso engxenyeni esentshonalanga kanti engxenyeni esempumalanga abona amazinga okushisa engaphansi kwesilinganiso ngo - 10 degrees. Ngokwe-Live Science, idatha yezwe lonke yabonisa ukuthi akukho sifundazwe esaba namazinga okushisa abandayo aqopha umlando ngoFebhuwari, kodwa amadolobha amaningi aphula amarekhodi awo. ENew York kwabekwa izinga lokushisa eliphansi elisha elingu - 13 degrees, elishaya irekhodi lakudala ngo - 1,6 degrees. Ngenyanga edlule kwakheka izingqimba ezinkulu zeqhwa phezu koMfula iHudson waseNew York okwaphoqa abe-US Coastguard ukuba basebenzise ama-ice breaker ukuze kugcinwe imikhumbi nemikhumbi ihamba. Abaqhubi bezikebhe edolobheni bakuchaza njengobusika obubi kunabo bonke ababa nabo eminyakeni engaphezu kwengu - 28. Kwavela nentaba-mlilo enkulu yeqhwa epaki laseNew York. Amarekhodi aphinde aphulwa nasezindaweni ezinjengeWorcester naseMassachusetts. Ngokuphambene nalokho, amazinga aphakeme kakhulu aqoshwa eWashington, eNevada naseCalifornia phakathi noFebhuwari, ngokusho kwaleli sayithi. ICalifornia iphakathi nesomiso esiyiminyaka emithathu esiye...  <response>: Imephu yesimo sezulu eyakhiwe kusetshenziswa idatha evela ku-Terra Satellite ye-NASA elinganisa izinga lokushisa komhlaba. Ibonisa ukuthi amazinga okushisa enyangeni edlule aqhathaniswa kanjani nalawo aqoshwa esikhathini esiyiminyaka eyi-10 kusukela ngo - 2001. Ibalazwe libonisa ukwehlukana kwamazinga okushisa phakathi empumalanga nentshonalanga yezwe.
