Kukho iiprojekthi ze-geoengineering ezijolise ekuphembeleleni utshintsho lwemozulu. Ezi ziiprojekthi ezizama ukunciphisa okanye ukubuyekeza iingxaki ezikhoyo kwiplanethi yethu ezineziphumo ezahlukeneyo zotshintsho lwemozulu.
Nangona kunjalo, iintshukumo ezenziwa kukwenziwa kwe-geoengineering ziphakamisa imibuzo yokuziphatha okuhle, kuba ineengozi ezahlukeneyo kwiplanethi. Ngaba uyafuna ukwazi ukuba kwenziwa ntoni ukunciphisa ifuthe lokutshintsha kwemozulu?
Ngobunjineli
Abaphandi abavela kwihlabathi liphela bezama ukwenza amashumi eminyaka ngolu hlobo lweprojekthi efuna ukumisa iimeko ezahlukeneyo zemozulu ngokuthanda ukubangela okanye ukuthintela imvula kwiindawo ezithile, ukulawula amanqanaba emitha yelanga okanye ukunciphisa i-carbon dioxide emoyeni.
Umzekelo, ukujongana nelanga ngokujongana nelanga lawula inani lokukhanya kwelanga okungena emoyeni, ukwenzela ukulawula ukufudumala komhlaba kunye nokunciphisa ukufudumala kwehlabathi. Kwiimodeli zovavanyo, isenzo se-geoengineering sinokuguqula imeko yotshintsho lwemozulu, nangona kungaziwa nokuba enyanisweni ingaba nesiphumo.
Imozulu yeplanethi iya kutshintsha ewe okanye ewe, nangona kunjalo, kunokwenzeka ukuzama ukunciphisa iimpembelelo zolu tshintsho lwemozulu. Obu buchwephesha bunokunceda abantu abaninzi kwaye banciphise ukwenzakala kwabanye, kodwa ngokuchaseneyo.
Ngapha koko, i-geoengineering ayisinciphisi isidingo sokwakha inkqubo yamandla acocekileyo kwaye sikhokele uqoqosho oluya kutshintsho lwamandla olusekwe kumandla acocekileyo ahlaziyekayo.
Ezinye iiprojekthi zolu hlobo ziyafumaneka kwimarike, njengoko oko kungqinwa kukuba ngo-Matshi 2012 uLuntu lwaseMadrid lwabela malunga ne-120.000 lama-euro kwiprojekthi yokwandisa imvula yekhephu ngobuchwephesha "bokulawulwa kwamafu" Inkampani yaseJamani iRadimeter Physics.
Iinkqubo zendalo ezilinganayo
Enye iprojekthi ye-geoengineering ukwenza imithi yokwenziwa enakho bamba kwaye ugcine i-CO2 njengeyona nto yokwenyani, kodwa ngesantya esiphezulu kunye nokusebenza kakuhle. Kukwakho neeprojekthi ezazisa i-microcrystals emajukujukwini ukuze imitha yelanga ibuyele ekulahleni intsimbi elwandle ukukhuthaza ukukhula kwezityalo ezincinci ezifunxa i-CO2 kwaye ziyitsalele emazantsi olwandle.
Ngale teknoloji sidlala ukuba sibe nguThixo kwaye kufuneka siyishiye ngoku sinalo ixesha, kuba indalo inemijikelezo yayo ngalo lonke ixesha kwaye asazi ukuba oku kunokuba nayiphi na imozulu.
