Soo koob maqaalka:  'Happy Feet' waxaa laga yaaba inay kicisay xiisaha caalamka ee xayawaanka penguin-ka ugu weyn, laakiin wax yar baa laga ogaa tirada is bedbedelaysa ee penguin-ka Emperor, ilaa hada. Daraasadii ugu horeysay ee ku saabsan sida cimilada Antarctica ay u saamaysay shimbiraha 30,000 sano ee la soo dhaafay waxaa sameeyay koox cilmi baarayaal ah, oo ay ku jiraan qaar ka socda Jaamacadda Tasmania iyo Waaxda Antarctic ee Australia. waxaa la ogaaday in waqtiyada qaar, in Antarctica ay ahayd mid aad u qabow shimbirahaas. Hoos u rog fiidiyowga. Xaaladaha barafka badda ee hadda jira ayaa ah kuwa ugu wanaagsan ee lagu noolaan karo penguin-ka boqortooyada, si kastaba ha ahaatee tani ma sii socon karto haddii kuleylka adduunku sii socdo. Noocyada ugu badan ee Penguin-ka aduunka ayaa haatan ku nool Antarctica iyadoo tiradoodu si aad ah usii kordhaysay 12,000 sano ee la soo dhaafay. Xilligii barafkii ugu dambeeyay, xaalada ayaa noqotay mid aad u daran taasoo keentay in dadka penguin-ka ah ay noqdaan todobo jeer in ka yar sida hada. Heerkulku wuxuu ka yaraa 15 darajo celcelis ahaan heerkulka maanta waxaana jiray sadex qoys oo penguin ah oo kaliya. Jane Younger oo ah hogaamiyaha cilmi baadhista ayaa sheegtay in inkastoo penguins-ka Emperor-ka ay caadeysteen heer kulka oo ah -30C, barafkii ugu danbeeyay waxa uu u muuqdaa in uu ahaa mid aad u qabow iyaga. Daraasadani waxay muujineysaa sida cimiladu u saamaysay shimbiraha 30,000 oo sano ee la soo dhaafay, iyadoo la ogaaday in Antarctica ay mar aad u qabow u ahayd. kuleylka ayaa u sahlay penguins-ka boqorada inay wax cunaan sida barafka badda uu u dhalaalay una yareeyay masaafada u dhaxaysa badweynta. "Maadaama ay jiraan laba jeer baraf badan marka la barbar dhigo xaaladaha hadda jira, penguins-ku ma awoodin inay ku dhalaan in ka badan dhowr goobood oo ku xeeran Antarctica", ayay tiri Ms Younger. Masaafada u dhaxaysa badweynta furan, halkaasoo ay ku quudiyaan penguins-ka, iyo barafka bada ee xasiloon halkaas oo ay ku tarmaan ayaa laga yaabaa inay aad u fogtahay. Waxyaabaha la helay waxay tusinayaan in xaaladaha barafka bada ee hadda jira ay u wanaagsan yihiin dadka penguin-ka ah. Markii uu soo ifbaxay noocyadii noolaha, baadhitaanku wuxuu muujiyay in tiradoodu ay bilaabatay inay kordho 12,000 oo sano ee la soo dhaafay...
Daraasadii ugu horeysay ee ku saabsan isbedelka tirada noocyada penguin-ka Emperor waxaa sameeyay saynisyahano. Xilligii barafka ugu danbeeyay, gumaysigu wuxu ka yaraa 7 jeer 50kii gumaysi ee hada jirtay. kuleylka ka jira Antarctica ayaa u sahlay in ay barwaaqoobaan maadaama barafka bada uu yaraaday ayna marin u heli karaan badweynta. Seynisyahannada ayaa ka digay in ay u nugul yihiin isbedelka cimilada iyo korodhka tiradan oo aan sii socon karin.
