Siqala unyaka omtsha. Incwadi entsha engenanto ivulelwe ukuba siyigcwalise ngobuqhetseba, ithemba, izigqibo kunye namaxesha, zombini zilungile kwaye zingalunganga kangako.

Iqondo lobushushu lehlabathi ngo-2017 linokuba phakathi kwe-0,63 kunye ne-0,87ºC ngaphezulu komndilili wexesha elide (ixesha le-1961-1990) le-14ºC, enoqikelelo oluphakathi lwe-0,75ºC. Usebenzisa i-avareji ye-1981-2003 yexesha elide ye-14,3ºC, uluhlu lwentelekelelo luphakathi kwe-0,32 kunye ne-0,56ºC ngoqikelelo oluphakathi lwe-0,44ºC, olwenza ukuba lube lolona hlobo lonyaka lufudumeleyo. kule minyaka imbalwa idlulileyo.

Umfanekiso- Met Office
Nangona kunzima ukwazi ncam ukuba kuzakwenzeka ntoni kwixesha eliphakathi nelide, ukufunda nokuhlalutya idatha kunye nokuthathela ingqalelo izinto ezinefuthe kwimozulu, ezinje nge-El Niño kunye ne-La Niña phenomena, izazinzulu zilungile ukuba kulo nyaka sisandula ukuwukhupha ube yenye yezona zishushu kwirekhodi kwihlabathi jikelele.
