<prompt> Pfupisa nyaya yacho: CNN Kunyange zvazvo nzvimbo huru yeUnited States yave ichidedera muchando chino, kwave kune chimwe chiratidzo chinonetsa chokudziya tembiricha kure kuchamhembe. Maererano neNASA, gore rino chando chegungwa chinopararira muArctic Ocean munguva yechando chinoita sechisina kumbobvira chaitika. Kukura kukuru kwegore rino, kwakasvika pana February 25, kwakanga kusiri bedzi kuduku zvikurusa munhoroondo yesatellite, kwaivawo kumwe kwokutanga. Kunze kwokukurumidza kukura kweaizi - kunobvira asi kusingabviri, maererano neshoko renhau reNASA - ikoku kunogadza muenzaniso mutsva. Ongororo iyi yakaitwa pachishandiswa mashoko anobva kuNational Snow and Ice Data Center NSIDC iri paUniversity of Colorado, Boulder, iyo inotsigirwa neNASA. Ice regungwa reArctic, mvura yegungwa yakaoma nechando iri kuyangarara pamusoro peArctic Ocean nemakungwa ayo akapoteredza, iri kuchinja nguva dzose. Inowedzera nzvimbo yayo munguva yechando, kazhinji ichisvika pakakwirira pakati pokupera kwaFebruary nokuvamba kwaApril, uye ipapo inoderera mukupisa kwechirimo nezhizha kuti isvike pakaderera zvikurusa muna September. Kana kukura kukuru kwegore rino, kunosvika mamiriyoni 5,61 mamaira akaenzana kumativi mana, kwakasvika pana February 25, kwakasvika mazuva 15 pamberi pomusi wepakati waMarch 12, 1981 kusvikira kuna 2010, maererano neNSIDC. Kamwe bedzi pamberi pezvi kwakanga kwambokurumidza kusvika, nezuva rimwe chete muna 1996. Nhamba yepamusoro yemakiromita mamiriyoni 5,61 akaenzana makiromita anenge 50 000 akaenzana makiromita ari pasi pemwero wepasi wepamusoro wenguva yechando, yakasvika muna 2011, maererano neNSIDC. Masayendisiti ave achishandisa mashoko anobva kumasatellite kuti aone kuchinja kuri kuitika muaizi yomugungwa reArctic, nzvimbo inokosha inogara shiri uye mhuka dzinoyamwisa dzomugungwa dzakadai semabheya anopisa, hove dzomugungwa, uye hove dzomugungwa, kwemakumi emakore anopfuura matatu. Maererano neNational Oceanic and Atmospheric Administration, Ted Scambos, musayendisiti anotungamirira weNSIDC, anotaura kuti chando chegungwa chakaderera zvikuru chakaitika gore rino chinogona kuva chando chiduku muPacific uye chando chakaderera muBarents Sea. Maererano neNOAA, mhepo dzakasimba dzokumaodzanyemba dzakatanga kuvhuvhuta muna March dzakabatsirawo. Nzvimbo yeBaffin Bay chete nemvura dzakapoteredza Newfoundland ndidzo dzaiva nechando chakawanda kupfuura chenguva dzose munguva yechando ino, rakadaro. Masayendisiti anoti...  <response>: Masayendisiti anotaura kuti chando cheArctic chinoita sechisina kunyanya kukura munguva yechando ino. Kunze kwokuwedzera kunenge kwava kuda kuitika kweaizi yomugungwa, muna 2015 yakakura kupfuura dzose yaiva mamiriyoni 5,61 emakiromita mana.
