Kafukufuku watsopano wa Nyanja Yatsopano akuwonetsa kuti madzi osungunuka a Antarctica a ku Antarctica akuchepetsa mafunde aku nyanja omwe amakopa dziko lapansi.
Nyanja zadziko lapansi zitha kuwoneka ngati yunifolomu mwachilungamo zikaonedwa kuchokera pa sitima kapena ndege, koma pamakhala zambiri pansi panthaka. Mitsinje yayikulu imatenga kutentha kuchokera ku malo obiriwira ku Arctic ndi Antarctica, komwe madzi amazizira kenako amayendanso ku equator. Anthu okhala ku East Coast waku North America ndi Europe amadziwa bwino za Gulf. Popanda icho, malo awa sangakhale osakhazikika, koma amakhala ozizira kwambiri kuposa iwo tsopano.
Makanema ojambulawa akuwonetsa njira ya bomba la dziko lonse lapansi. Mivi ya Blue imawonetsa njira yakuya madzi akuya, yozizira, yowirira. Mivi yofiira imawonetsa njira yotentha, yocheperako yamadzi. Akuyerekeza kuti "paketi" ya madzi imatha kutenga zaka chikwi kuti amalize ulendo wawo wa lamba wapadziko lonse lapansi. GAWO LAKUDYA: Noaa
Madzi a nyanja ndi, kotero kuti ayankhule, dongosolo lagalimoto. Ngati china chilichonse chimasokoneza chopondera chozizira chazomwe chimakhala nacho, china chake sichingachitike ku injini yanu. Zomwezi zimachitikanso padziko lapansi ngati mafunde am'madzi amasokonekera. Sikuti amangothandiza kuyendetsa kutentha kwadziko lapansi, koma amaperekanso michere yofunika yofunika pa moyo wa m'madzi. Pamwambapa ndi chithunzi chomwe NoaA amafotokoza momwe mafunde amangiramo amangiramonga. Pansipa pali malongosoledwe a Noa.
"Kufalitsidwa kwa Thermohan kumayendetsa mafunde apadziko lonse lapansi omwe amapezeka padziko lonse lapansi. Lamba wonyamula amayambira panyanja pafupi ndi mitengo ya North Atlantic. Apa madzi amayamba kumera chifukwa cha kutentha kwa Arctic. Imakhalanso ndi mchere chifukwa mafomu a nyanja, mchere samazizira ndi kukhalabe m'madzi ozungulira. Chifukwa cha mchere wowonjezereka, madzi ozizira amakhala otenda ndi kumira pansi panyanja. Kuchuluka kwa madzi pansi m'malo mwa madzi akumira, kupanga mafunde.
"Madzi akuya awa amasunthira kum'mwera, pakati pa mandimbiro, kumbali ya equator ndi njira yonse mpaka kumapeto kwa Africa ndi South America. Madzi am'madzi amayenda mozungulira m'mphepete mwa Antarctica, pomwe madziwo amaziziranso ndi kumira, monga kumpoto kwa Atlantic. Ndipo zitero, lamba wovomerezeka "wachita. Atayenda mozungulira antarcarctica, magawo awiri osiyana ndi lamba wonyamula ndikutembenukira kumpoto. Gawo limodzi limalowa mu Indian Ocean, ndipo gawo linalo ku Pacific Ocean.
"Pamene tisunthira kumpoto kulowera ku equator, magawo awiriwa amapatuka, kutentha, ndikukhala wocheperako akamakwera pamwamba. Kenako amabwerera kumwera ndi kumadzulo kwa Atlantic ndipo kenako ku North Atlantic, komwe kuzungulira kumayambanso.
"Mimba yonyamula miyala imayenda pang'ono pang'onopang'ono (masentimita angapo pa sekondi) kuposa mphepo kapena mafunde am'munsi (ma makumi asanu ndi limodzi). Akuyerekeza kuti mita iliyonse yamkati yamadzi imatenga zaka pafupifupi 1000 kuti amalize ulendo wawo padziko lonse lapansi. Ulendo wa lamba wonyamula kuphatikiza kuphatikiza, lamba wonyamula katundu amanyamula madzi ambiri - oposa 100 kutuluka kwa mtsinje wa Amazon.
"Malamba onyamula mabulosi ndi gawo lofunika kwambiri pakuzungulira michere ndi kaboni dayokisi kunyanja za padziko lapansi. Madzi ofunda amadzaza michere ndi kaboni dayokisi, koma amalemekezedwanso pamene akudutsa kudzera mwa lamba wowoneka ngati zigawo zakuya kapena gawo lapansi. Maziko a chakudya padziko lapansi. Kudalira kumadzi ozizira, otentha kwambiri omwe amathandizira kukula kwa algae ndi Kelp. "
Phunziro latsopano lofalitsidwa pa Marichi 29 mu magazini mwachilengedwe limawonetsa kuti monga Antarcarctica amathamangitsa, madzi osaputa mafunde ozizira amatha kuchepetsera mafunde akulu awa omwe alibe 2050. Izi zimamveka bwino, koma zimatha kuyambitsa chisanu cha chilala, kusefukira kwamadzi ndi kukwera kwa nyanja. Kafukufuku akuwonetsa kuti kuchepetsa mafunde oyanjana kumatha kusintha nyengo ya dziko. Izi zitha kukhala ndi zotsatirapo zosiyanasiyana, kuphatikiza kuchuluka kwa nyanja, kusintha nyengo ndi kuthekera kwa moyo wa Hunry Marine popanda kupezeka pamavuto ofunikira.
Pulofesa Mat England, kuchokera ku yunivesite ya New South Wales "M'mbuyomu, zidatenga zaka zopitilira 1,000 kapena kotero kuti zinthuzi zisinthe, koma tsopano zimangotengera zaka makumi angapo. Izi zikuchitika mwachangu kwambiri kuposa momwe timaganizira, zinthu izi zikuchepa. Tikulankhula za kutha kwa nthawi yayitali. iconic Madzi. " "
Kuchepa kwa mafunde akuya akunyanja kumachitika chifukwa cha kuchuluka kwa madzi pansi panyanja kenako kumayenda kumpoto. Dr Qaria Li, yemwe kale anali ku yunivesite ya New South Wales ndipo tsopano mwa Massachusetts Institutets Institutets Institutetion Institutets Institutests Institutets Institutes Institute Institute of Technology, ndiye Woyambitsa Phunziro la phunziroli, lomwe linagwirizanitsidwa ndi England. Mavuto azachuma "adzasintha kwambiri mayankho a Nyanja kutenthe, madzi abwino, mpweya ndi michere, ndi michere ya padziko lapansi kwazaka zambiri mpaka zaka zambiri zikubwerazi," Alembawo alemba. Mphamvu imodzi ikhoza kukhala kusintha kwamvula mumvula - malo ena amatenga mvula yambiri ndipo ena amayamba kuchepa.
"Sitikufuna kupanga njira zodzilimbitsa m'malo omwe ali m'malo akuti," Lee anati, ndikuwonjezera kuti kutha kwadzidzidzi kwasunthika panyanja yakuya, kuluka kwa mpweya wa oxygen. Zolengedwa zakunyanja zikafa, zimawonjezera michere kumadzi omwe amatsikira pansi panyanja ndipo amazungulira nyanja zonse padziko lapansi. Zakudyazi zimabwereranso nthawi yodzaza ndi chakudya cha phytoplankton. Uwu ndi maziko a chakudya cham'madzi.
Dr Steve Rinturoul, yemwe adazisedwa ku Sourcean, yemwe anali ndi zaka zakumadzi a ku Australia sayansi ya ku Australia ndi mafashoni, amasenda michere yocheperako, ochepera a Phytoplankton. m'zaka za zana.
"Akangokulirakulira, titha kuyambiranso kumasulidwa kwa madzi osungunuka mozungulira ku Antarctica, komwe kumatanthauza kuti timafunikira nyengo yozizira kenako ndikudikirira kuti ayambenso. Tinapitiriza mpweya wowonjezera kutentha kwambiri, timadikirira, tikamadzipereka kwambiri kuti tisinthe kwambiri. Ndikakumbukira zaka 20 zapitazo, tinaganiza kuti nyanja yakuya idasinthiratu. Anali kutali kwambiri kuti achite. Koma kuwonera ndi mitundu kunena zina. "
Pulofesa Stefan Rahmstorf Percest Unictions Unissanes ku Potsdam Institute Kufufuza Kwapafupipafupi, adati Lipoti la dera lalikulu la malo lili ndi zolakwa za UN 'ndi zophophonya zazitali kwambiri chifukwa sizimawonetsa kuti madzi agunda akugunda nyanja. "Madzi osungunuka amachepetsa mcherewo m'madzi am'madzi omwewa, ndikupangitsa madzi kukhala ochepa kwambiri kotero ilibe kulemera kokwanira kumira ndikukankhira m'madzi kale."
Pakatikati pa kutentha kwa dziko lapansi kukukwera, pali mgwirizano pakati pa mafunde am'nyanja ndi momwe mungafunire kuphatikizira dziko. Onsewa adzakhala ndi mavuto osayembekezeka kwambiri omwe angakhale ndi zotsatira zowononga m'miyoyo ya anthu ambiri padziko lapansi.
Njira yothetsera vutoli, imachepetsa mpweya wa kaboni dioxide ndi methane, koma atsogoleri adziko lapansi achedwa kutcheratu mavuto awa chifukwa kuchita izi kungayambitse mafuta ogulitsa zinthu zakale. Mafuta amathira magalimoto, kutentha nyumba ndi mphamvu intaneti.
Ngati United States inali yokhudza kupanga ogula amalipira zotayika zotayika, mtengo wa magetsi owotcha miyala itha kupitirira kapena katatu, ndipo mtengo wa mafuta amatha kupitirira $ 10 galoni. Ngati zili choncho pamwambapa, ovota ambiri amafuula ndikuvota kwa ofuna kutanthauza kuti abwezeretse masiku akale abwino. Mwanjira ina, tipitilizabe kulowera tsogolo losatsimikizika, ndipo ana athu ana ndi zidzukulu zathu adzamva zowawa za kulephera kwathu.
Pulofesa Rahmstorff anati mbali ina yakudana youluka mafunde a ku Antaltrica ndikuti kuchepetsa mphamvu zozama za mpweya zomwe zitha kusungidwa munyanja yakuya. Titha kuthandiza kuchepetsa izi pochepetsa mpweya wa kaboni ndi methane, koma pali umboni pang'ono kuti agonjera azichita izi.
Steve akulemba za kulumikizana kwaukadaulo ndi kusakhazikika kunyumba kwake ku Florida kapena kulikonse komwe mphamvu ingamutenge. Anali wonyadira kuti "wobwezera" ndipo sanasamale chifukwa chomwe galasi litasweka. Amakhulupirira ndi mtima wonse m'mawu a Socates, analankhulidwa zaka 3,000 zapitazo kuti: "Chinsinsi cha kusintha ndikungoganizira za mphamvu zanu zonse sizingamenyane ndi zakale, koma pomanga watsopano."
