ʻO ka heheʻe o ka muliwai o ke alahouana e hōʻike ana i kahi pōʻino ... pili ia i kona mau kui.

I loko o kahi ʻōlelo hōʻeuʻeu, ua ʻōlelo aku ka nui o nā ʻepekema ʻo "Thwaites Iceberg" nui ma ke komohana o Antarctica, ke alo nei i kahi hoʻi hope ʻole, hiki ke hoʻoweliweli i ka honua.

Ua ʻike lākou ʻo ka Thwaites glacier, i kapa ʻia ʻo Resurrection Glacier, hiki ke emi koke i nā makahiki e hiki mai ana, e hāpai ana i nā hopohopo e pili ana i ka piʻi nui ʻana o ka ʻilikai e pili ana i kona make ʻana.

Ma kahi noiʻi i paʻi ʻia i ka Pōʻakahi ma ka puke pai Nature Geoscience, ua kahakaha nā ʻepekema i ka hoʻi hope o ka glacier, me ka manaʻo e aʻo mai kona wā i hala a wānana i ka hana a ka glacier i ka wā e hiki mai ana.

Ua ʻike pū lākou i kekahi manawa i nā kenekulia ʻelua i hala iho nei, ua mae ke kumu o ka glacier mai ka papahele o ke kai a ua emi hope ma kahi o 1.3 mau mile (2.1 kilomika) i kēlā me kēia makahiki, ʻelua ka nui o ka helu o nā ʻepekema i ʻike ai i nā makahiki i hala a i ʻole. pela.

Ua hiki mai paha kēia hoʻoheheʻe wikiwiki "e like me ka waena o ke kenekulia XNUMX," i ʻōlelo ʻia ʻo Alistair Graham, ka mea kākau alakaʻi o ka noiʻi a me kahi geophysicist moana ma ke Kulanui o South Florida.

Ua ʻike pū ʻo ia, hiki i ka muliwai ke hoʻihoʻi wikiwiki i ka wā e hiki mai ana, i ka wā e emi ai ma waho o kahi kuamoʻo i ka papahele o ke kai e kōkua i ka mālama ʻana.

"paʻa i kona mau kui"

Ua ʻōlelo ʻo Robert Larter, he geophysicist moana a me kekahi o nā mea kākau o ka noiʻi mai ka British Survey: "Ke paʻa maoli nei ka muliwai i kona mau manamana lima i kēia lā, a pono mākou e manaʻo e ʻike i nā loli nui i nā unahi manawa liʻiliʻi i ka wā e hiki mai ana - mai ka makahiki. i ka makahiki - i ka wā e emi ai ka muliwai. ʻo ka glacier ma waho aʻe o kahi papa pāpaʻu ma lalo.

ʻO ka Thwaites Glacier, aia ma West Antarctica, kekahi o nā mea nui loa ma ka Honua a ʻoi aku ka nui ma mua o ka mokuʻāina o Florida.

Akā, he ʻāpana wale nō ia o ka pā hau o West Antarctic, kahi i lawa ka hau e hoʻokiʻekiʻe i ka ʻilikai ma kahi o 16 kapuaʻi, e like me ka NASA.
