Kodi limatsogolera zina madzi oundana Greenland chiyani?

Mwatsoka, kuyambira kusaina wa Kyoto pangano vuto nyengo padziko lathuli ndi zovuta. Komanso, pa zapitazi theka ya atumwi icho chakhala anakula kwambiri kuyambira mlingo wa ayezi limatsogolera ku Greenland ndi Antarctica ali kwambiri inapita patsogolo.

nkhawa kwambiri asayansi kusungunuka madzi oundana Greenland, ndi zatsopano zomwe dziko silinakwaniritsidwe olembedwa. Akatswiri amanena kuti kudzakhala kotheka kuti moyenerera amatchedwa "wobiriwira chilumba" chifukwa ayezi pa izo asakhalebe m'mbuyomu zaka 30 chidwi, mlingo wa ayezi limatsogolera wakula kwambiri kuti zaka zingapo, Greenland.

Nkhawa ndi kuti ngakhale pa mfundo apamwamba Chilumbachi zodabwitsa, pamene ayezi sanali kusungunula kwa zaka, monga limatsogolera madzi oundana akhala lokhazikika. Akuti ngati kuchuluka kale kusungunula anali osapitirira 40%, koma tsopano chathandiza kuti 97%. Chinthu choyipa ndi asayansi sitingapeze kumufotokozera za zodabwitsazi.

Zingapo utatha chakuti ayezi mwina obwezeretsedwa, koma izi sizikuchitika mofulumira ngati zomwe zinali patsogolo. Pafupifupi tsiku lililonse la Greenland ayezi pepala akuthawa ndalama zambiri ayezi, kukula kwa omwe nthawi zambiri ndi zoopsa. Dera wina wa namkholowa izi kuti tsopano kusungidwa mu yobwerera pafupi ndi gombe la Canada upambana 200 sq. Km!

Kodi linaopseza lathuli? Chinthu chowopsya kuti limatsogolera oundana cha 2012 ungamuphe nyamuka zoopsa mu mlingo wa Ocean World. Asayansi ukuonetsa kuti pambuyo limatsogolera lathunthu la Greenland ayezi iye akhoza kukula mamita 6 basi. Iwo ayenera kumvetsa kuti kulera mlingo wa yekha mita ndi zinadzala ndi masoka zosaneneka. Ngati limatsogolera madzi oundana adzapitiriza pa mlingo chomwecho, ndiye anthu adzakhala ndi nthawi yovuta.

Makamaka asayansi amenewa akuneneratu n'zotheka ndi mosayembekezeka kusamuka kwa tectonic mbale chifukwa kumasulidwa mofulumira pansi pa misa zosaneneka amene mbamuikha pa iwo Zakachikwi wina. Ngati zolosera awa, ndiye limatsogolera madzi oundana imfayo pakutchulidwa wachiwiri "mphete ya moto" mapiri pa dziko. Only nthawi iyi malo kuphulika sadzakhala mu wosavuta kwa ife ku Pacific Ocean, ndipo monga gombe la Europe.

Kodi n'zotheka kuteteza zotsatirapo zoipazi? Mwatsoka, kokha mwina. Kulepheretsanso akuthamanga wa mofulumira ayezi pa dziko kwathunthu, sitingathe. Mulimonsemo, pa mlingo lino la zaumisiri. Komanso, sitingathe motsimikiza chimene chinayambitsa mtengo koteroko mofulumira ayezi: zochita za anthu kapena ena, sakudziwika kwa ife zifukwa.

Tikhoza mosamala yekha kuwunika limatsogolera madzi oundana yake kukhwimitsa kuti asachoke anthu ku midzi owopsa nyanja komanso m'midzi. Kungathandize kwambiri ndi ntchito kopitirira seismologists, amene akhoza kutsimikizira kapena kutsutsa chiphunzitso cha kusuntha mbale tectonic.
