Titha kupeza ma komisheni ogwirizana mukagula kuchokera ku maulalo patsamba lathu.Umu ndi momwe zimagwirira ntchito.
Kafukufuku watsopano wasonyeza kuti North Pole ikutsamira ku Siberia kuchokera kwawo kwa makolo awo ku Canadian Arctic pamene magulu awiri akuluakulu obisika pansi pa nthaka kumapeto kwa malaya akumenyana.
Mawanga awa, madera omwe ali ndi maginito opanda mphamvu pansi pa Canada ndi Siberia, akuchita nawo nkhondo yopambana.Pamene madontho amasintha mawonekedwe ndi mphamvu ya maginito, pali wopambana;Ofufuzawa adapeza kuti ngakhale kuchuluka kwamadzi pansi pa Canada kudachepa kuchokera ku 1999 mpaka 2019, kuchuluka kwa madzi ku Siberia kudakwera pang'ono kuchokera ku 1999 mpaka 2019. mu phunziro.
"Sitinawonepo izi," Phil Livermore, wofufuza wamkulu komanso wothandizira pulofesa wa geophysics ku yunivesite ya Leeds ku United Kingdom, adauza Live Science mu imelo.
Pamene asayansi anapeza koyamba North Pole (kumene kampasi singano) mu 1831, anali kumpoto kwa Canada gawo la Nunavut.Posakhalitsa ofufuzawo adazindikira kuti kumpoto kwa maginito kumakonda kusuntha, koma nthawi zambiri sikutali kwambiri.Pakati pa 1990 ndi 2005, mlingo umene mitengo ya maginito inasuntha inalumpha kuchokera pa liwiro la mbiri yakale la 9 mailosi (15 kilometers) pachaka mpaka 37 miles (60 kilomita) pachaka, ofufuza akulemba mu phunziro lawo.
Mu Okutobala 2017, maginito akumpoto adawoloka mzere wapadziko lonse lapansi kum'mawa kwa dziko lapansi, ndikudutsa mkati mwa 242 miles (390 kilometers) kuchokera ku geographic North pole.Kenako maginito a kumpoto akuyamba kulowera chakum’mwera.Zambiri zasintha kotero kuti mu 2019, akatswiri a sayansi ya nthaka adakakamizika kumasula chaka chotsatira mtundu watsopano wa maginito wapadziko lonse lapansi, mapu omwe amaphatikizapo chilichonse kuyambira paulendo wandege kupita ku smartphone GPS.
Munthu angangolingalira chifukwa chake Arctic inachoka ku Canada kupita ku Siberia.Zinali choncho mpaka Livermore ndi anzake anazindikira kuti madonthowo ndi amene anachititsa.
Mphamvu ya maginito imapangidwa ndi chitsulo chamadzimadzi chomwe chimazungulira mkatikati mwa dziko lapansi.Choncho, kusintha kwa kulemera kwachitsulo chogwedezeka kumasintha malo a maginito kumpoto.
Komabe, mphamvu ya maginito siimangokhala pachimake.Malinga ndi Livermore, mizere ya maginito "imatuluka" padziko lapansi.Zikuoneka kuti madontho awa amawonekera kumene mizere iyi ikuwonekera."Ngati mukuganiza kuti mizere ya maginito ndi sipageti yofewa, madontho ake amakhala ngati tinthu tating'onoting'ono totuluka Padziko Lapansi," adatero.
Ofufuzawo adapeza kuti kuchokera ku 1999 mpaka 2019, gombe la ku Canada lomwe lidayenda kuchokera kummawa kupita kumadzulo ndikugawika magawo awiri ang'onoang'ono olumikizidwa, mwina chifukwa cha kusintha kwa kayendedwe kake pakati pa 1970 ndi 1999. zina, koma zonse, elongation "zinathandiza kufooka kwa malo Canada padziko lapansi," ofufuza analemba mu kafukufuku.
Kuphatikiza apo, malo ovuta kwambiri aku Canada adayandikira ku Siberia chifukwa chakugawanika.Izi, zinalimbitsa malo a ku Siberia, ochita kafukufuku akulemba.
Komabe, midadada iwiriyi ili pachiwopsezo chovuta, kotero "zosintha zazing'ono zokha zomwe zingasinthidwe zomwe zingasinthe zomwe zikuchitika ku North Pole kulowera ku Siberia," ofufuzawo adalemba mu kafukufukuyu.Mwanjira ina, kukankhira kumalo amodzi kumatha kutumiza maginito kumpoto kubwerera ku Canada.
Kukonzanso kwa kayendedwe ka maginito ku North Pole kumasonyeza kuti madontho awiri, ndipo nthawi zina atatu, akhudza malo a North Pole pakapita nthawi.Pazaka 400 zapitazi, madonthowa achititsa kuti North Pole ichedwetse kumpoto kwa Canada, ofufuza akutero.
"Koma m'zaka zapitazi za 7,000, [North Pole] ikuwoneka kuti yayendayenda molakwika popanda kusonyeza malo omwe amawakonda," ofufuzawo analemba mu kafukufukuyu.Malinga ndi chitsanzo, pofika 1300 BC, mtengowo unasamukira ku Siberia.
Ndizovuta kunena zomwe zidzachitike pambuyo pake."Zomwe timaneneratu ndikuti mitengoyi ipitilira ku Siberia, koma kulosera zam'tsogolo ndizovuta ndipo sitingatsimikizire," adatero Livermore.
Zoneneratu zidzakhazikitsidwa pa "kuwunika mwatsatanetsatane gawo la geomagnetic padziko lapansi komanso mumlengalenga pazaka zingapo zikubwerazi," ofufuzawo adalemba mu kafukufuku yemwe adasindikizidwa pa intaneti pa Meyi 5 m'magazini ya Nature Geoscience.
Kwa kanthawi kochepa, mutha kulembetsa ku magazini athu aliwonse ogulitsa kwambiri asayansi pamtengo wochepera $2.38 pamwezi kapena 45% kuchotsera pamtengo wanthawi zonse wa miyezi itatu yoyambirira.
