kia puta te pānga o te huringa āhuarangi ki kia nuinga kino engari i reira he he wahi tu a kanapa mō te hunga e uaua ana ki te kite te wa nui i roto i te ra: Kei te meinga kōpaka rewa te huringa o te whenua ki te pōturi reira tawharara tatou ra, Kua kitea rangahau hou.

Kua whakaratohia Harvard University kairangahau he whakahoki ki te Conundrum roa-tū i runga i te pehea e holomui e pā kōpaka te huringa me te tuaka o te whenua, te tātai e kua roa te roanga o te ra i te hākonamano mo te mua 100 tau.

Nga frein Ka atu koi tono ki hurihanga o te whenua kia rite ki ngohe kōpaka i te tere tere ake, tikanga e ka tapiritia i te iti rawa e rima hākonamano ki ia ra i runga i te akoranga o te rautau 21. Ka nuku te tuaka o te whenua rawa, ki te pou raki whakaturia ki te neke tūranga e pā ana ki 1hm (o.4in) i roto i tenei rau tau.

te rangahau, whakaputaina i roto i te Nama Pūtaiao, āhua kitea he panga pūtaiao mohiotia rite "kupu whakarite a Munk", i haere mai i te 2002 pepa kairangahau i te oceanographer Walter Munk, ui pehea puta te rewa o kōpaka i te hurihanga, me te tuaka o te whenua.

Ka rite ki te tio whenua i te amo rewa tika ki maranga pāmahana kōhauhau, kia meinga te taimaha o te wai puta noa te ao neke i te huringa ki te tuaka ki runga ki e huringa te whenua, me te tītaka iti i roto i te hurihanga. Ano, ka meinga te taimaha o te wai ki te weheruatanga tapiritia te whenua ki te pōturi, nui i roto i te ara e pōturi te kōpaka pōtaka ahua, ki te tae ia ranei ia ratou ringa i roto atu i to ratou tinana.

ngä Munk i te pānga o te mutunga o te Age Ice 5,000 matahiti i ma'iri a'e, ka ngohe i runga i te mua 15,000 e kua tau i tauturu pōturi hurihanga o te whenua. Ko, Koinei, kitea ia e ara ki whakatika taumata moana toharite o te 2mm tau i roto i te rau tau 20, kahore he huringa ki te hurihanga o te whenua tuaka ranei tua atu i meinga e te Ice Age mutu.

"He kia kua he tohu nui kaumaatua a e reira tonu rite reira anake e ra wiki ranei mo taua wai rewa i te amo ki te hūnuku a tawhio noa te ao,"Ka mea a Jerry Mitrovica, ahorangi o Geophysics i University Harvard me rangatira o te rangahau.

haere hoki ki te rangahau a Munk kapa o Mitrovica ka tono te matauranga pūtaiao hou ki reira. kitea e ratou i paku piriponotanga Munk te taumata moana ara toharite - ko reira a tawhio noa 1mm ki 1.5mm ia tau i runga i te rau tau 20, nui atu i 2mm.

Ratou tono ano he tauira whakahoutia ki te tātai. riro Munk i tere whakaritea te whenua ki te tio rewa i puta rite mutu te Ice Age. Ētahi atu māramatanga tata o tenei wa, Heoi, fokotu'u e kore ko rite porohita te whenua rite te mea i teie nei hoki te wa roa, rite meinga nga pepa tio nui ki nga amo ki te whakaparaha me te weheruatanga Pupuhi i roto i.

Kia i ngä te kapa i roto i te tahi atu mau mana pērā i te tai, kitea e ratou i meinga pono te rewa kōpaka o te rau tau 20 te whenua ki te pōturi me tītaka. Ka taea te tirohia te tere o te hurihanga o te ao i inenga o tūranga whetu 'i roto i te pā ki te whenua, me te hoki te ohuraa o āmiorangi, e whai ki te whakarite paku ki te huringa hurihanga o te ao.

whakaturia ana tēnei āta te ki riro atu korerotia. Te ao te taumata moana ara toharite ko inaianei i runga i 3mm, rite ki te IPCC, ki te rōrahi o kōpaka o te ao whakaturia ki te tautuku i waenganui 15% a 85% e 2100, i runga i te āhua me pehea koi whakaiti iwi tukunga haurehu kati kōtuhi me whakamuri ngahere papatipu.

kitea te ako tata e te taui o kōpaka o te ao o nāianei ko "mua tuatahi", ki te kaipūtaiao whakatupato e te awa kōpaka nui i roto i Greenland e mau nui te wai ki te whakaara taumata moana ao e te hawhe mita Kua timata ki te hu'ahu'a ki te Te Tai Tokerau Atlantic Ocean. Kei te hoki ka pupü mai te taumata moana ara i waiariki roha, te wahi tupu te moana rite mahana te reira ake.

"Ko te wā o te ra he inaianei he hākonamano roa atu i te rau tau i mua engari e ka whakatere rite nga piki rewa,"Ka mea a Mitrovica. "E kore e tangata e rere i to ratou whare hamama e pā ana ki te hākonamano anō engari tāpiri reira haamauraa ano atu o ta tatou e mahi ki to tatou taiao. Ko te tetahi atu tapumati. "
