Ama-glaciers emhlabeni wonke ayanyamalala kancane ngenxa yokushintsha kwesimo sezulu. IPeru ithathwa njengelinye lamazwe asengozini enkulu emiphumeleni yokuguquka kwesimo sezulu emhlabeni. Isizathu salokhu ukuthi ilahlekile eminyakeni engama-55 kuphela, u-61% wawo wonke amaqhwa ayo.
Lokhu kuzoba nemiphumela emibi njengokuchichima kwamachibi ngenxa yokuncibilika ngokweqile kweqhwa nokusweleka kwamanzi esikhathini esizayo. Kuzokwenzekani lapho iPeru ilahlekelwa izinguzunga zeqhwa?
Izinguzunga zeqhwa ziyanyamalala
IPeru yayinamakhilomitha-skwele ayi-1.035 wezinguzunga zeqhwa ezisatshalaliswa ngaphezu kwezintaba eziyi-16 ezineqhwa. Namuhla, ama-61% alawo maqhwa ancibilika ngenxa yokushisa komhlaba. Ngokuya ngophenyo lwakamuva olwenziwe yiNational Institute for Glaciers and Mountain Ecosystems Research, izinguzunga zeqhwa ezithwesa umqhele i-Andes yasePeru zisenkingeni yokuqothulwa ngoba kusukela ngo-1962 balahlekelwe yisilinganiso saminyaka yonke samakhilomitha-skwele ayi-11,5.
Le panorama ebucayi ikhombisa ukuthi imiphumela yokuguquka kwesimo sezulu iya ngokusobala futhi iyinhlekelele enkulu. Ucwaningo lubona ukunyamalala kwezinguzunga zeqhwa ezintabeni zaseChila, nase-Arequipa, okumanzi ayo yiwona enza uMfula i-Amazon uqhelelene kakhulu, nalapho kushiye khona cishe ama-200 square metres, ngokulahlekelwa ngama-99% wamakhilomitha-skwele angama-34 acishe abekhona maphakathi nekhulu lama-XNUMX.
Izinguzunga zeqhwa ezithinteka kakhulu ekushintsheni kwesimo sezulu yilezo ezitholakala ebangeni eliphansi, ngoba amazinga okushisa aphezulu ngaphezulu futhi ancipha njengoba ukuphakama kukhuphuka (lena yi-gradient ezishisayo yemvelo). Izinguzunga zeqhwa eziphakeme futhi ezinkulu zimelana kakhulu, yize zizonyamalala maduzane.
Ukuguquka kwesimo sezulu kwenza izinguzunga zeqhwa emhlabeni wonke zinyamalale futhi lokhu kuzoholela ezinkingeni ezinkulu ngokwandayo.
