Abantu abazizigidi ezi-2.000 baya kuba ziimbacu zemozulu ngowama-2100

Izigidigidi zabantu kuya kufuneka ukuba bafuduswe ngenxa yokutshintsha kwemozulu

Ubushushu behlabathi bubangela ukuba izigaqa zomkhenkce ezibandayo zanyibilika kwaye Oku kubangela ukunyuka kwinqanaba lolwandle. Zininzi izixeko ezingaselunxwemeni ezithi, ukuba ulwandle luyaqhubeka ukunyuka, luya kusala lungekho unxweme. Abantu ekufuneka behambile okanye bafudukele kwezinye iindawo ngenxa yoku kunyuka kwenqanaba lolwandle okanye ezinye izizathu ezinxulumene nokunyuka kwesantya kunye nokuqina kweziganeko zemozulu ezigqithisileyo (njengezaqhwithi, izikhukula, imbalela ...) babizwa ngokuba ziimbacu zemozulu.

Kuqikelelwa ukuba ngonyaka wama-2100, abantu abazizigidi ezibini (esi iya kuba sinye kwisihlanu sabantu behlabathi ngelo xesha) banokuba ziimbacu zemozulu, ikakhulu ngenxa yokunyuka kwenqanaba lolwandle.

Utshintsho lwemozulu kunye neembacu

Iimbacu zemozulu ziya kwanda ngakumbi nangakumbi

Izigidi nezigidi zabantu bahlala kwiidolophu eziselunxwemeni ezisongelwa ngakumbi yimeko yezulu enjengeenkanyamba, izikhukula, kunye nokunyuka kwamazinga olwandle abangelwa kukutshintsha kwemozulu. Aba bantu banobomi babo, usapho lwabo, abahlobo, abasebenza njalo njalo, bayanyanzeleka ukuba bafudukele kwezinye iindawo ezikhuselekileyo nezinokuhlala abantu bangaphakathi ixesha elide.

Isifundo senziwe kwiYunivesithi yaseConell esithi sizakuba nabantu abaninzi kwihlabathi elinomhlaba omncinci kwaye oku kuyakwenzeka msinyane kunokuba sicinga.

Ngokunyuka komphakamo wolwandle, bonke abantu abahlala kwimimandla eselunxwemeni kuya kufuneka bafudukele kwiindawo ezikhuselekileyo emhlabeni. Kwelinye icala, inani labemi behlabathi liyanda minyaka le. Ke konke oku kukhokelela ekubeni kuhlaliswe abantu abaninzi nangakumbi kumhlaba ongahlali bantu. UCharles Geisler UNjingalwazi we-Emeritus woPhuhliso lweNtlalontle kwiYunivesithi yaseCornell, ucacisa ukuba ukunyuka kwenqanaba lolwandle elizayo ngekhe kuphuhlise inkqubela phambili, kodwa kungaqala ukunyuka ngokukhawuleza. Ngaphandle kwezi zibikezelo zichanekileyo zisuka kwezenzululwazi, Abapolitiki abayithathi imithintelo ebalulekileyo ekungeneni kweembacu zemozulu zonxweme, Njengabanye ababaleki, baya kubafumana xa befudukela kwindawo ephezulu.

Uqikelelo lwexa elizayo

ukukhutshwa ngenxa yokunyuka komphakamo wolwandle kwizixeko eziselunxwemeni

Ngokweengxelo zeZizwe eziManyeneyo, uluntu kulindeleke ukuba ukwanda ukuya kwi-9.000 yezigidigidi zabantu ngo-2050 kunye ne-11.000 yezigidigidi ngo-2100. Nangona kunjalo, siya kuba nomhlaba omncinci wokulima, indawo encinci yokuphucula inani labemi, kwaye ukunyuka kwamanqanaba olwandle kuya kutshabalalisa iindawo ezininzi ezinokulinywa, ezinje ngemilambo yolwandle, iindawo ezichumileyo, njl. Kwaye konke oku kuyakwenza ukuba abantu bafune iindawo ezintsha zokuhlala.

Malunga, I-2.000 yezigidigidi zabantu banokuba ziimbacu zemozulu nge-2100. Ukungqubana kokuchuma kwabantu, ukuntywila kwimimandla eselunxwemeni, indawo yokuhlala ebalekayo, kunye nezithintelo zokuhlala ngokutsha elizweni yingxaki enkulu. Ngeli xesha kuya kubakho iingxaki ezininzi ezinkulu ezinje ngeembacu zemozulu, iimfazwe zemithombo yendalo, ukwehla kwemveliso yeplanethi, iindawo ziya kufuneka ukugcina ii-greenhouse gases ezihlawulela ukunyibilika komkhenkce kunye nokugawulwa kwamahlathi, njl. Uqikelelo lumdaka ngekamva elilindele izizukulwana zangoku.

Olu xwebhu luchaza izisombululo ezibonakalayo kunye nohlengahlengiso olusebenzayo kwiindawo ezinjengeFlorida ne China, ezilungelelanisa imigaqo-nkqubo yokusetyenziswa komhlaba elunxwemeni nakwilizwe elilindelwe utshintsho olwenzeka kubemi bemozulu. IFlorida inelunxwemeni lwesibini olude kunayo yonke iUnited States kwaye kuye kwakho ukufuduka konxweme okuboniswa kuMthetho woRhulumente oCwangcisiweyo oCwangcisiweyo.

Ayisiyiyo kuphela ukuphakama kolwandle okuxhalabisayo, kodwa nezinye iimeko ezigabadeleyo ezinje ngezaqhwithi okanye izaqhwithi ezikweleenjiko Ungatyhala amanzi olwandle ngaphakathi. Ngokwembali, abantu benze umzamo omkhulu wokubuyisa umhlaba kwiilwandlekazi, kodwa ngoku bahlala ngokuchaseneyo: iilwandle ziphinda zibuyisele umhlaba umhlaba
