Iine chimiro chayo chakareba chakareba, iyo Morteratsch Glacier muSwitzerland ndeimwe yenzvimbo dzinoshanyirwa kwazvo munyika, asi iri zvakare imwe yevanonyanya kutambura nekukwira kwetembiricha. Gore rega rega anorasikirwa nemamita makumi matatu kusvika makumi manaSaka kana pasina chakaitwa chingangoenda nekukurumidza.
Kuti vadzivise izvi, vakafunga nzira yekusimbisa nayo: 4.000 michina yechando inotora mukana wemvura kubva mumadhamu akaumbwa nekuda kwekunyungudika kugadzira chando, icho chinoshandiswa kufukidza chikamu chepamusoro chegirazi. Zvaringana here?
Kubva pane zvidzidzo zvekare, masayendisiti anotenda kuti Morteratsch anogona kudzosa 800 metres mumakore makumi maviri. Asi kuti uzive kana zvichinyatsoshanda, chinhu chekutanga chavachaite kuisa nzira iyi kuchikamu chidiki cheDiavolezzafirm glacier munguva ino yezhizha (2017). Iyo yekutanga chirongwa inodhura madhora zviuru zana, masayendisiti akaudzwa Musayendisiti.
Kana mhedzisiro yacho yakanaka, Nyanzvi dzinoti zvinokwana kuchengetedza nzvimbo inokwana masikweya kilomita nehafu yakatetepa yechando chakagadzirwa nemasendimita mashoma kubva kuMorteratsch. Zvakadaro, hatigone kukanganwa kuti mhedzisiro huru yechando kuratidza kwezuva.
Kunyanya kunongedza mwaranzi yezuva inosvika, kwete chete iyo tembiricha ichave yakakwira, asi sinou, iyo chena, inonyungudika nekukurumidza.. Izvi ndizvo zvinozivikanwa se albedo mhedzisiro, uye tinogona kuzvisimbisa nekutora kirimu lolly muchando uye zvakare imwe muzhizha. Panguva yechando inogona kutora hafu yeawa kana kupfuura kuti inyungudike, muzhizha unoiburitsa kunze uye inotanga kunyungudika.
Kana nyika ikaramba ichidziya, mazaya echando aigona kuve nemazuva avo akaverengwa. Uye kana zvikanyangarika, mwero wegungwa unokwira kutenderera pasirese, zvichikonzera matambudziko mazhinji kune vese vanogara kumahombekombe uye kuzvitsuwa zvakaderera.
