Yiziphi ezinye zezindlela isintu esingasebenza ngazo ngokushesha ukuze sipholile iplanethi ukuze sinciphise imiphumela yokufudumala kwembulunga yonke?
Omunye umqondo isintu esingawusebenzisa ukuze sipholile ngokushesha iplanethi ukuze sisize ekunciphiseni imiphumela yokufudumala kwembulunga yonke kungaba ukuvimba okunye noma konke ukukhanya kwelanga (imisebe ye-UV) eshaya iplanethi ivela elangeni. Ngezinye izikhathi ezibizwa ngokuthi i-GeoEngineering, lezi yizinhlelo ezisesilinganisweni esikhulu ngempela. Ngokwesibonelo, iphrojekthi enjengalena ingase iqukathe imikhumbi emikhulu yelanga ekhanyayo noma enye impahla ekhanyayo ekwazi ukuphakama emkhathini ongaphezulu ukuze ikhanyise okunye noma konke ukukhanya kwelanga kubuyele emkhathini. Omunye umqondo kungaba ukudala ama-scrubber amakhulu futhi aningi e-CO2 ukuze kususwe inani elibonakalayo legesi ebamba ukushisa, i-CO2, esebenza ukubonisa nokuvimbela ukushisa okuvela eplanethi ukuba kungaphinde kuphumele emkhathini. Ukunciphisa kakhulu inani le - CO2 emkhathini wethu bekuyokwenza ukuba ukushisa okwengeziwe kuphunyuke kule planethi futhi ngenxa yalokho kuyipholisise. Nokho omunye umcabango ungase ube ukukhulisa ngobuciko futhi kakhulu ubukhulu beziqongo zethu zeqhwa okungaholela ekukhanyeni kwelanga okuningi okubuyiselwa emuva emkhathini. Enye indlela kungaba ukulingisa imvelo ezikhathini zangaphambili lapho kwakunentaba-mlilo eningi khona bese kufakwa isulphur dioxide eningi emkhathini ngethemba lokudala izimo ezaholela ezikhathini zeqhwa ezincane esikhathini esidlule.
