Soo koob maqaalka:  Heerkulka caalamku si dhaqso ah uma kordhin sida la filayay, sida lagu sheegay daraasad cusub oo ku saleysan 1,000 sano oo diiwaanada heerkulka ah. Cilmi baaristu waxay sheegeysaa in isbedelka dabiiciga ah ee heerkulka dusha sare ee tobanka sano ay sababi karto kor u kaca iyo hoos u dhaca heerarka kuleylka. Laakiin waxay intaa ku dartay in waxa loogu yeero 'isbedelka cimilada' ay sidoo kale mustaqbalka sababi karaan in dhulkeenu uu si ka dhaqso badan sidii la filayay u kululaado. Hoos u rog fiidiyowga. Daraasaddan ayaa lagu barbardhigay natiijooyinkeeda xaaladaha ugu daran ee qiiqa ee ay soo bandhigeen Guddiga Dowladaha ee Isbedelka Cimilada (IPCC). Isbeddelka heerkulka ee la saadaaliyay ee IPCC laga bilaabo 2081-2100 ayaa lagu sawiray halkan. Si kastaba ha ahaatee, daraasaddii ugu dambeysay, waxay sheegtay in qaabkan cimiladu uu khaldan yahay. Daraasaddan ayaa lagu barbardhigay natiijooyinkeeda xaaladaha ugu daran ee qiiqa ee ay soo bandhigeen Guddiga Dowladaha ee Isbedelka Cimilada (IPCC). "Annaga oo ku saleysan falanqeynteena, xaaladda kuleylka ee dhexdhexaadka ah ayaa u badan tahay, ugu yaraan hadda", ayuu yiri Patrick Brown, oo ah arday dhakhtar ka ah cilmiga cimilada ee Jaamacadda Duke. Laakiin tani way is beddeli kartaa. Daraasad uu hogaaminayo Duke ayaa sheegaya in kala duwanaanshaha ay sabab u tahay is dhexgalka badaha iyo jawiga, iyo waxyaabo kale oo dabiici ah. Waxay ku andacoodaan in 'jilicsanaanta' ay hoos u dhigi karto ama ay dardargelin karto heerka kuleylka toban sano ilaa toban sano, iyo in la badsado ama la yareeyo saameynta kororka gaaska aqalka dhirta lagu koriyo. Haddii aan si sax ah loo sharaxin loona xisaabtamin, waxay qalloocin karaan kalsoonida moodellada cimilada waxayna keeni karaan in si xad dhaaf ah loo fasiro isbeddellada heerkulka ee muddada gaaban. Isku soo wada duuboo isbeddelada la saadaalinayo ee waxsoosaarka dalagga ee warbixin hore ee IPCC. Sababtoo ah 'isbeddelka cimilada' lama xisaabtamin, cilmi-baarayaasha Jaamacadda Duke waxay yiraahdaan warbixinta waxaa laga yaabaa inay ahayd fasiraad xad dhaaf ah oo ku saabsan isbeddelka heerkulka muddada-gaaban. Cilmi baaristu waxay isticmaashaa xogta la arkay, halkii ay ka isticmaali lahaayeen moodooyinka cimilada ee sida caadiga ah loo isticmaalo, si loo qiyaaso kala duwanaanshaha tobanaan sano. Waqti kasta, waxaan bilaabi karnaa kuleylka xawaare ka dhakhso badan haddii cufnaanta gaaska aqalka dhirta lagu koriyo ee hawada sare u kaco iyadoon wax isbedel ah ku imaan cufnaanta aerosolka...
Daraasad ay samaysay jaamacada Duke University ayaa lagu baaray 1000 sano oo diiwaanada heerkulka ah. Waxay isbarbar dhig ku samaysay isbeddellada ugu daran ee hawada ee ay samaysay IPCC. Waxay ogaadeen in isbedelka dabiiciga ahi uu hoos u dhigi karo ama uu dardar galin karo heerka kuleylka. 'Isbedelada cimilada' si sax ah looma tixgelin warbixinta IPCC.
