Uye ndizvozvo, »kana paizove nenjodzi yemamiriro ekunze, zvingangotangira muThwaites"Sezvakafanotaurwa naIan Howat, chiremba wezvekucherechedzwa kweOhio. Asi nei?
Ichando cheAntarctica chinonyunguduka zvakanyanya kunge imba yemakadhi, ndiko kuti, izvo Anogara akatsiga kusvika asundidzirwa. Kunyangwe iri chiitiko chisingazoitika nehusiku, mune makumi emakore kurasikirwa kweTwaites glacier kuchadzikamisa yasara yechando kumadokero kwekondinendi. Kana ndangoita, ichaisa njodzi kune avo vanogara mukati memakiromita makumi mashanu kubva kumahombekombe, ndiko kuti, hafu yechiverengero chavagari vapasi.
Mwero wegungwa unogona kukwira nezvikamu zvitatu mumativi mazhinji epasi, uye kusvika kumana mune mamwe akaita seNew York kana Boston.
