Kukho konke ukuphila kwakhe, umuntu ngokungalawuleki wasebenzisa izinzuzo zemvelo, ezaholela ekuveleni kwezinkinga eziningi zemvelo zesikhathi sethu. Ukuvinjelwa kwenhlekelele yomhlaba kusezandleni zomuntu. Ikusasa loMhlaba lincike kithi kuphela.
Amaqiniso aziwayo
Iningi lososayensi licabanga ukuthi inkinga yokufudumala kwembulunga yonke ivele ngenxa yokuqongelelwa kwamagesi abamba ukushisa emkhathini womhlaba. Zivimbela ukushisa okuqoqiwe ukuthi kungadluli. Lawa magesi akha i-dome engajwayelekile, okuholela ekwandeni kwezinga lokushisa, okudala ushintsho ngokushesha kumaqhwa. Le nqubo ithinta kabi isimo sezulu jikelele seplanethi.
I-massif enkulu yeqhwa isendaweni yase-Antarctica. Izendlalelo ezinkulu zeqhwa ezweni elinomthelela ekunciphiseni kwalo, futhi ukuncibilika ngokushesha kunomthelela ekwehleni kwendawo isiyonke yezwekazi. Iqhwa lase-Arctic linobude obungamamitha-skwele ayizigidi eziyi-14. km.
Imbangela enkulu yokufudumala
Ngemuva kokwenza inqwaba yezifundo, ososayensi baphethe ngokuthi isizathu esiyinhloko sale nhlekelele ezayo ngumsebenzi wabantu:
- ukugawulwa kwamahlathi;
- ukungcoliswa kwenhlabathi, amanzi nomoya;
- ukukhula kwamabhizinisi okukhiqiza.
Izinguzunga zeqhwa ziyancibilika yonke indawo. Kule minyaka eyikhulu edlule, izinga lokushisa lomoya lenyuke ngama-degree ama-2,5.
Kunombono ososayensi wokuthi inqubo yokufudumala kwembulunga yonke inamandla, futhi yethulwa kudala futhi ukubamba iqhaza kwabantu kuyo kuncane. Lokhu kuyithonya elivela ngaphandle elihlotshaniswa ne-astrophysics. Ochwepheshe kule ndawo babona imbangela yezinguquko zesimo sezulu ekuhlelweni kwamaplanethi nezindikimba zasezulwini emkhathini.
Imiphumela engaba khona
Kunemibono emine enengqondo
- Izilwandle zizokhuphuka ngamamitha angama-60, okuzodala ukuguquka kolwandle futhi kube imbangela enkulu yezikhukhula zasogwini.
- Isimo sezulu emhlabeni sizoshintsha ngenxa yokuhamba kwemisinga yolwandle, kunzima kakhulu ukubikezela imiphumela yalolu shintsho ngokucace kakhudlwana.
- Ukuncibilika kwezinguzunga zeqhwa kuzoholela kwizifo eziwumqedazwe, ezizohlanganiswa nenani elikhulu lezisulu.
- Izinhlekelele zemvelo zizokwanda, kuholele endlaleni, isomiso, kanye nokushoda kwamanzi ahlanzekile. Abantu kuzodingeka bafudukele ezweni.
Kakade manje, umuntu uhlangabezana nalezi zinkinga. Izifunda eziningi zihlushwa yizikhukhula, ama-tsunami amakhulu, ukuzamazama komhlaba, ukuguquka kwezimo zezulu. Kuze kube manje, ososayensi emhlabeni wonke balwela ukuxazulula inkinga yokuncibilika kwezinguzunga zeqhwa eGreenland nase-Antarctica. Zimelela ukunikezwa okucebe kakhulu kwamanzi ahlanzekile, okuthi, ngenxa yokufudumala, ancibilike angene olwandle.
Futhi olwandle, ngenxa yokuhlanjululwa emanzini, inani lezinhlanzi, elisetshenziselwa ukudoba abantu, liyancipha.
Ukuncibilika kweGreenland
Izixazululo
Ochwepheshe basungule izinyathelo eziningi ezizobamba iqhaza ekujwayelekile kwezinkinga zemvelo:
- ukufaka ukuvikeleka okukhethekile emzileni womhlaba usebenzisa izibuko nama-shutter afanele ezinguzini zeqhwa;
- zala izitshalo ngokuzalanisa. Zizobhekelwa ekumuncekeni okunempumelelo kakhudlwana kwesikhutha;
- sebenzisa eminye imithombo yokukhiqiza amandla: faka ama-solar panel, ama-wind turbines, izikhungo zamandla olwandle;
- ukudlulisela izimoto kweminye imithombo yamandla;
- qinisa ukulawula amafektri ukudikibala okungatholakali ukuthi kukhishwa malini.
Izinyathelo zokuvikela inhlekelele yomhlaba kumele zithathwe yonke indawo nakuwo wonke amazinga kahulumeni. Le ukuphela kwendlela yokubhekana nenhlekelele ezayo nokunciphisa inani lezinhlekelele.
