Tsvagiridzo itsva yegungwa inoratidza kuti antarctica's Meltwater iri kudzora magungwa akadzika magungwa ayo anopesvedzera zvakananga mamiriro ekunze epasi.
Makungwa epasi rese anogona kuratidzika seyunifomu yakajeka kana ichionekwa kubva padanda rechikepe kana ndege, asi pane zvakawanda zviri kupaza pasi. Huge nzizi dzinotakura kupisa kubva kuTropics kuArctic uye Antarctica, uko mvura inotonhorera uye inozoyerera zvakare yakananga ku equator. Vanhu vanogara pamhenderekedzo yekumabvazuva kweNorth America neEurope vanoziva rwizi rweGulf. Pasina iyo, idzi nzvimbo dzaisazove dzisingachinjiki, asi dzaizotonhora zvakanyanya kupfuura zvavari ikozvino.
Iyi mijenya inoratidza nzira yePilobal pipiresi. Miseve yebhuruu inoratidza nzira yekudzika, inotonhora mvura inoyerera. Miseve dzvuku inoratidza nzira yemidziya inodziya, zvishoma pasi pemvura mvura. Zvinofungidzirwa kuti "paketi" yemvura inogona kutora makore chiuru kuti upedze rwendo rwayo kuburikidza nePasi rose Conveyor Belt. Mufananidzo unobva: NOAA
Mahwindo emakungwa aripo, saka kutaura, iyo inotonhorera system yemotokari. Kana paine chinokanganisa kuyerera kwakajairika kwekutonhora, chimwe chinhu chakaipa chinogona kuitika kune injini yako. Chinhu chimwe chetecho chinoitika pasi pano kana magungwa emakungwa akakanganiswa. Hazvisi chete zvavanobatsira kutungamira tembiricha yepasi pevhu, asi ivo vanopawo zvinovaka muviri zvinodiwa nekuda kwehupenyu hwemakungwa. Pamusoro pane dhayadhi yakapihwa naNoaa inotsanangura kuti maExanes anoshanda sei. Pazasi ndeyeNeaa's yekutaura tsananguro.
"Kutenderera kweTheMermohaline kunotyaira nyika yepasirese yeanodururwa kwegungwa inonzi Clobal Conveyor. Bhandi rebhandi rinotanga pagungwa pamusoro pematanda okumusoro atlantic. Pano mvura inova inotonhorera nekuda kweArctic tembiricha. Izvo zvakare zvinova munyu nekuti apo mafuro egungwa mafomu, munyu haasunungurwe uye unoramba mumvura yakakomberedza. Nekuda kweiyo yakawedzerwa munyu, mvura inotonhora inova denser uye inonyura kune pasi pegungwa. Kufambisa kwemvura yemvura kutsiva mvura inonyura, kugadzira mafungu.
"Iyi mvura yakadzika inoenda kumaodzanyemba, pakati pemakondinendi, iyo nzira yeequator uye nzira yese yekuguma kwe Africa neSouth America. Mahwindo egungwa anoyerera akatenderedza mipheti yeAntarctica, uko mvura inotonhorera zvakare uye kunyura, seyekuchamhembe atlantic. Uye saka ndezvekuti, bhandi rinoti "rakapihwa mhosva." Achifambisa kutenderera Antarctica, zvikamu zviviri zvakaparadzaniswa nebhandi rebhandi uye tendeukira kuchamhembe. Chikamu chimwe chinopinda muIndia Ocean, uye chimwe chikamu kuPacific Ocean.
"Patinofamba kuchamhembe takananga ku equator, zvikamu zviviri izvi zvinoputsa, zvinodziya, uye tisingakwanisi kusimuka sezvavanosimuka. Ivo vanobva vadzoka zasi uye kumadokero kweSouth Atlantic uye pakupedzisira kuenda kuNorth Atlantic, uko kutenderera kunotanga zvakare.
"Mabhandi anobatanidza anofamba zvishoma nezvishoma Zvinofungidzirwa kuti chero met met met metheni yemvura inotora anenge makore mazana mashanu kuti apedze rwendo rwacho kutenderera pasi rose. Rwendo rwebhandi rebhandi rekuwedzera mukuwedzera, bhandi rinosimudzira rinotakura huwandu hwakawanda hwemvura - dzinopfuura ka zana kuyerera kweRwizi rweAmazon.
"Mabhandi anobvumidza zvakare akakosha chikamu chekutenderera kwezvinhu zvinovaka muviri uye carbon dioxide mumakungwa epasirese. Mvura inodziya inopera mune zvinovaka muviri uye carbon dioxide, asi ivo vanofumiswa zvakare pavanenge vachipfuura nepakati pebhandi rakadzika kunge nzvimbo dzakadzika kana substrate. Hwaro hwepasirese chikafu cheni. Kuvimba nemvura inotonhorera, ine hutano-pfupfuuri inotsigira kukura kwe algae uye Kelp. "
Chidzidzo chitsva chakabudiswa munaKurume: Mubhuku Rinodziya Semunhu Anodziya, mvura kubva kuMelting Galciers inokwanisa kuderedza aya makuru egungwa nemakumi mairi nemakumi mairi nemakumi maviri. Izvi zvinonzwisiswa zvakanaka, asi zvinogona kutungamira mukuwedzera kwemvura, mafashama uye nhanho dzegungwa dzinobuda. Tsvagurudzo inoratidza kuti kudzora maheji emakungwa kunogona kuchinja mamiriro ekunze epasirese kwemazana emakore. Izvi, zvakare, zvinogona kuve nemhedzisiro, kusanganisira inokurumidza kufamba kwegungwa, ichichinja maitiro emamiriro ekunze uye mukana wekuti une nzara yehupenyu husina kuwana kune zvakakosha zvinyorwa zvezvinhu zvakakosha.
Muzvinafundo Matt England, kubva kuYunivhesiti yeNew South Wales 'Center Yekuchinja Kwemamiriro ekunze uye Co-Munyori weChinyorwa chakabudiswa mune yeChirungu, chakaziviswa negungwa razvino raive pane yayo yazvino trajectory yekudonha. "Munguva yakapfuura, zvaitora makore anopfuura chiuru kana kuti idzo dzidziso dzekuchinja, asi zvino zvinongotora makumi emakore mashoma. Izvi zviri kuitika nekukurumidza kupfuura zvataifunga, idzi cycle dziri kudzikisa. Tiri kutaura nezve zvinogoneka kwenguva yakareba kutsakatika. "IMIC yemvura masasi." "
Kunonoka kweiyo yakadzika yegungwa inokonzerwa nehuwandu hwemvura kunyura kune pasi pegungwa uye wozoyerera kuchamhembe. Dr Qian Li, aimbove weYunivhesiti yeNew South Wales Wales uye iye zvino eMassachusetts Institute of Technology, ndiye mutungamiri weChidzidzo cheNyanga, iyo yakarongedzwa neEngland. Kuderera kwehupfumi "kuchashandura zvakanyanya mhinduro yemakungwa kupisa, mvura yakachena, kabhoni, kabhoni uye zvinovaka, nezvinorehwa nemazana emakore anouya," vanyori vanonyora. Imwe mhedzisiro inogona kuve shanduko yakakosha mukunaya kwemvura - dzimwe nzvimbo dzinowana mvura yakawanda uye vamwe vanowana zvishoma.
"Hatidi kuumba mashandisirwo emasimba munzvimbo idzi," Lee akadaro, achiwedzera kuti kunonoka kwakanyatsoomesa nyora nyanza, ichinyima okisijeni. Kana zvisikwa zvegungwa zvinofa, zvinowedzera zvinovaka muviri kumvura inonyura kune pasi pegungwa uye kutenderera mumakungwa epasirese enyika. Izvi zvinovaka muviri zvinogara zvichigara zvichigara uye zvinoshanda sechikafu che phytoplankton. Ichi chigadziko chechipenga chekudya cheni.

"Kana kutenderera kwekuparadza kunonoka, tinogona chete kutangazve nekumisa kusunungurwa kweMeltwater kutenderera Antarctica, zvinoreva kuti tinoda kutonhora mamiriro ekunze uye tobva tamirira kuti itangezve. Yedu yakaenderera yakakwira greenhouse gasi egasi kunze kwenguva yakareba tinomirira, ndipo patinozoita kuti tikwanise kuchinja zvakanyanya. Tichitarisa kumashure makore makumi maviri apfuura, takafunga kuti gungwa rakadzika rakanga risina kuchinja zvakanyanya. Aive kure zvakanyanya kuti aite. Asi kucherechedza uye mhando zvinoti zvimwe.

Muzvinafundo Stefan Rahmstorf, Musoro wePasi System Ongorora kuPotdam Institute Yekutarisa Kwemamiriro ekunze ekudzivirira. Mushumo weMatimisa eUN. "Mvura inonyunguduka inofamba-famba munyu mune idzi nzvimbo dzegungwa, uchigadzira mvura isina kushambadzira saka haina uremu hwakakwana kuti inyure uye kusundira mvura yatovepo."
Sezvo avhareji epasi rose tembiricha ichiramba ichikwira, pane chinongedzo pakati pekudzora makungwa emakungwa uye zvinodikanwa zvekuda kuti geoengineering kutonhorera pasi. Ivo vaviri vachave nemhedzisiro isingafungidziriki inogona kuve nemhedzisiro inokuvadza pahupenyu hwevanhu munzvimbo dzakawanda dzepasi.
