ISahel, iluhlaza ngenxa yeMedithera efudumele

Sahel

I-Planet Earth iyiplanethi ephilayo, kangangoba uma amazinga okushisa enyuka endaweni eyodwa, awela kwenye ukugcina ukulinganisela kokushisa komhlaba wonke. Okufanayo kuzokwenzeka ngeMedithera neSahel: kule minyaka engama-20 edlule, isifunda saseMedithera besilokhu sibhekene nokwanda kwamazinga okushisa nokwehla kwemvula, izimvula ezibonakala zifudukele eSahel, njengoba kuvezwe ocwaningweni olushicilelwe ephephandabeni i-Nature Climate Change, olwenziwe yiMax Planck Institute for Meteorology.

Ngenxa yokwanda kwamazinga okushisa eMare Nostrum, umswakama ofinyelela umkhawulo oseningizimu weSahara ekuqaleni kwesiphepho saseNtshonalanga Afrika ngoJuni nawo uphakeme, ngakho-ke iSahel iba luhlaza.

Isimo sezulu saseSahel sihluka kakhulu, siphethwe yisiphepho saseNtshonalanga Afrika, esiletha imvula kusuka ngoJuni kuya kuSepthemba. Ukuphela konyaka, isomiso sinamandla kakhulu. Umhlaba ushisa ngaphezu kolwandle ehlobo, ngoba ilanga lisendaweni ephakeme futhi, ngaphezu kwalokho, izilwandle azimunci ukushisa ngokushesha njengomhlaba. Umoya ukhuphuka usuka ezwekazini futhi ngokwenza lokho ukhiqiza ukugeleza komswakama ovela olwandle uye eSahel.

Amandla emvula abelokhu ehluka ngokuhamba kwesikhathi. Phakathi konyaka we-1950 nowe-1960, iSahel yaba nesikhathi esimanzi; Ngawo-1980, isomiso sasinamandla kangangokuba abantu abangaphezu kuka-100.000 XNUMX balahlekelwa yizimpilo zabo. Kusuka lapho, imvula yabuya.

Imbangela ngokusho kososayensi ithi Ukufudumala kweMedithera. Ukufinyelela kuleso siphetho, izimo ezahlukahlukene zafundwa kusetshenziswa ukulingisa okuhlukahlukene. Ngakho-ke, bakwazi ukuthola ukuthi uma izinga lokushisa endaweni yaseMedithera lihlala lingaguquguquki, imvula eSahel ayikhuli; kunalokho, uma iMedithera iyafudumala, eSahel lina kakhulu.

Lokhu kungenxa yokuthi akugcini nje ngokukhuphuka kwezinga lokushisa, kodwa futhi nomswakama, okuyilokho "okwenza kusebenze" imvula yaseNtshonalanga Afrika. Ngale ndlela, kule ngxenye ye-Afrika, bangajabulela izimvula eziningi ekuqaleni kwenkathi yemvula.
