Kunezizathu eziningi zokucwila kancane kancane kobuso boMhlaba, kodwa isisindo samadolobha ngokwawo akuvamile ukuba sifundwe.
The cwaningo ithole ukuthi iNew York icwila ngamamilimitha angu-1-2 ngonyaka ngenxa yesisindo samabhilidi amade. Amamilimitha ambalwa angase angabonakali maningi, kodwa ezinye izingxenye zedolobha zicwila ngokushesha okukhulu.
Ukuguqulwa kungadala inkinga edolobheni eliphansi elinabantu abangaphezu kwezigidi ezingu-8. Le miphumela kufanele ikhuthaze eminye imizamo yokuthuthukisa amasu okunciphisa ukuguquguquka kwesimo sezulu ukuze kuliwe nokwanda kwengozi yezikhukhula kanye nokukhuphuka kwezinga lolwandle.

Kulolu cwaningo olusha, abacwaningi babale isisindo esihlanganisiwe sezakhiwo ezingaba yizigidi ezingu-1 eNew York City zibe amakhilogremu angu-764,000,000,000,000,000. Base behlukanisa idolobha laba igridi yesikwele yamamitha ayi-100 x 100 futhi, ngokucabangela amandla adonsela phansi, baguqula ubuningi bezakhiwo baba ukucindezela okuya phansi.
Izibalo zabo zifaka kuphela inqwaba yezakhiwo nezinto ezingaphakathi kuzo, hhayi imigwaqo yaseNew York, imigwaqo yaseceleni, amabhuloho, izitimela, nezinye izindawo ezigandayiwe. Ngisho noma kunale mingcele, lezi zibalo ezintsha zithuthukisa okuphawulwe ngaphambili kokuwa kwedolobha ngokucabangela indawo eyinkimbinkimbi yokuma komhlaba engaphansi kweDolobha laseNew York, ehlanganisa izinsalela zesihlabathi, udaka, nobumba, kanye namadwala aphuma emadwaleni.
Ngokuqhathanisa la mamodeli nedatha yesathelayithi echaza ukuphakama komhlaba, ithimba lanquma ukuthontelana kwedolobha.

Ingxenye yesine yenhloko-dolobha yase-Indonesia, iJakarta, ngo-2050 ingagcina ingaphansi kwamanzi njengoba izingxenye zedolobha zicwila cishe ngo-11 cm ngonyaka ngenxa yokukhipha amanzi angaphansi komhlaba. Izakhamuzi zaseJakarta ezingaphezu kwezigidi ezingu-30 manje sezicabanga ukufuduka.
Uma kuqhathaniswa, iDolobha laseNew York likleliswe endaweni yesithathu ngokwengozi yezikhukhula zesikhathi esizayo. Ingxenye enkulu yeManhattan ephansi ingamamitha angu-1 ukuya kwangu-2 kuphela ngaphezu kwezinga lolwandle lwamanje. Iziphepho zango-2012 nango-2021 ziphinde zakhombisa ukuthi idolobha lingashesha kangakanani ukugcwala izikhukhula.
Ngo-2022, ucwaningo lwamadolobha angama-99 asogwini emhlabeni wonke lwathola ukuthi ukwehla kungenzeka kube kukhulu kunalokho okulinganiselwe. Emadolobheni amaningi ahlolisisiwe, umhlaba ucwila ngokushesha kunokuba izinga lolwandle likhuphuka, okusho ukuthi izakhamizi zizobhekana nezikhukhula ngokushesha kunokuba izibonelo zesimo sezulu zibikezela.
