Ngisho nalapho kushisa kakhulu, izihlahla zezindiza emadolobheni zisanegalelo elibalulekile ekupholiseni - lokhu kuboniswa ucwaningo olusha oluholwa yi-Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). Inhloso manje ukunquma ukuthi yiziphi izinhlobo zezihlahla ezisebenza kahle kakhulu ekupholiseni.
Lapho ilanga lishisa, izihlahla zasemadolobheni zipholisa indawo ezungezile ngokuhwamulisa amanzi ngamahlamvu azo. Uma kubhekwa ukwanda okulindelekile kwamagagasi okushisa, njengoba kubikezelwe izibonelo zesimo sezulu, adlala indima ebalulekile ekugcineni amadolobha akwazi ukuphila. Nokho, izihlahla zigcina zifinyelele imingcele yazo: Lapho amazinga okushisa amaqabunga ekhuphuka ngaphezu kuka-30 kuya ku-35 degrees Celsius, i-photosynthesis ayisasebenzi - izimbotshana zamaqabunga ziseduze ukuze kuvinjelwe ukulahlekelwa kwamanzi.
Ithimba locwaningo elivela eSwiss Federal Institute for Forest, Snow and Landscape Research WSL kanye ne-EPFL manje seliphenye ngqo ukuthi izihlahla zezindiza ziziphatha kanjani ngaphansi kwezimo ezimbi kakhulu - ngemiphumela emangalisayo: Ngisho nasemazingeni okushisa angaphezu kwama-degree Celsius angu-39, izihlahla zaqhubeka nokuhwamuka kwamanzi amaningi kakhulu kunalokho obekulindelekile, ngaleyo ndlela zipholisa indawo ezungezile ngempumelelo.
Umholi wocwaningo u-Christoph Bachofen nethimba lakhe bafake izinsiza zokulinganisa ezihlahleni zendiza eziyisishiyagalombili endaweni engaphansi kwe-Geneva e-Lancy entwasahlobo ka-2023. Izinzwa zirekhode ukugeleza kobisi eziqwini, okuvumela ukuthi kufinyelelwe esiphethweni mayelana nenani lamanzi ahwamukile kanjalo namandla okupholisa. Ngalo lelo hlobo ehlobo, iGeneva yabhekana namagagasi okushisa amabili anamazinga okushisa arekhodiwe afinyelela cishe kuma-degree Celsius angama-40.
Ngokuphambene nalokho okwakulindelwe, izihlahla azizange zimise ukugeleza kwamanzi - ngokuphambene nalokho: Njengoba ukushisa kwanda, empeleni kwanda, nakuba umoya wawuwome kakhulu ngesikhathi esifanayo. "Ngokusobala, asikaqondi ngokugcwele ukuthi izihlahla zisabela kanjani ezimweni ezimbi kakhulu," kuchaza u-Bachofen. Abacwaningi basola ukuthi, phakathi kwezinye izinto, izindawo zokugcina amanzi ajulile emhlabathini zisize izihlahla zendiza. Izinga lokugeleza kwamanzi lalimangalisa futhi liphakamisa imibuzo ebalulekile: Uma izihlahla zisabela ngendlela ehlukile ekushiseni kunalokho okwakucatshangwa ngaphambili, izibikezelo zomphumela wazo wokupholisa nazo azinembile - futhi amamodeli asetshenziselwa ukubikezela ukusatshalaliswa kokushisa okuzayo emadolobheni angeke athembeke.
Iqiniso lokuthi izihlahla zihwamulisa amanzi amaningi ngisho nalapho kushisa kakhulu kuyizindaba ezinhle zesimo sezulu sasemadolobheni. "Izinsuku ezinamazinga okushisa angaphezu kuka-30 degrees Celsius ziya ngokuya zivame," kusho uBachofen. Isinyathelo esilandelayo esibalulekile socwaningo siwukuthola ukuthi ezinye izinhlobo zezihlahla zenzeka ngempumelelo kangakanani ekushiseni okukhulu. Lokhu kuzokwenza kube nokwenzeka ukuthuthukisa izincomo zezinhlobo ezingakwazi ukubhekana nokungcoliswa komoya kuphela nosawoti womgwaqo, kodwa futhi nokushisa okukhulu. Umthamo wokupholisa ungomunye wemisebenzi eminingi eyenziwa izihlahla zasemadolobheni - kodwa izobaluleka kakhulu esikhathini esizayo.
