Kunyaka ophelileyo kuye kwafudumala okoko idatha yaqala ukurekhodwa ngo-1880. Ngobushushu obungu-1,1ºC ngaphezulu kunangexesha langaphambi kokushishina, ubuntu ngoku buya kwindawo engaziwayo, nto leyo eza kubeka imeko yayo ngoku esichengeni. indlela yobomi ngaphandle kokuba uthathe amanyathelo angxamisekileyo okuthintela oko.
Makhe siyiqwalasele irekhodisha imozulu eqhekekileyo ngo-2016.
NgoLwesibini, nge-21 Matshi 2017, i-WMO ipapashe ingxelo yayo yonyaka ngemeko yemozulu yehlabathi, esekwe kwidatha yamanye amazwe efunyenwe ngokuzimela ngamaziko ohlalutyo lwemozulu lwehlabathi. Ke, ngenxa yolu papasho, siya kuba nakho ukufumana umbono wento eyenzekayo kwiplanethi iphela, hayi kuphela kwindawo esihlala kuyo.
Utshintsho lwemozulu sisiganeko sehlabathi kwaye ke ngoko sichaphazela iplanethi iphela. Ngokwengxelo, hayi kuphela iqondo lobushushu eliphakathi lalingu-1,1ºC ngaphezulu kwexesha laphambi kokusebenza, elaliyi-0,6ºC, kodwa iqondo lobushushu kumphezulu wolwandle laliphezulu kunesiqhelo.

Ngokunyuka kwamanqanaba ecarbon dioxide emoyeni, iimpembelelo zezinto ezenziwa ngabantu kwimozulu ziya zisanda ngokwandautshilo uNobhala Jikelele we-WMO uPetteri Taalas. Kuba izixhobo zekhompyuter zangoku ziyafumaneka, ezinakho ukuqokelela kunye nokuthelekisa idatha, oososayensi banokubonisa ukuba abantu banegalelo elingakanani kutshintsho lwemozulu.
Yiyo ke le nto, sinokwazi ukuba kule minyaka ili-16 idlulileyo unyaka ubuncinci ubunobushushu obungu-0,4ºC kunalowo ungaphambili, sithathe ixesha elingu-1961-1990 njengesalathiso. Ngexesha lesenzeko se El Niño ukusuka ngo-2015/2016, umphakamo wolwandle wenyuka ngaphezu kwesiqhelo, ngelixa umkhenkce osezibondeni unyibilika.
Ngobushushu obushushu, iziganeko zemozulu ezibi kakhulu zenzekile, ezinje imbalela enkulu emazantsi nasempuma ye-Afrika nakuMbindi Merika. Kananjalo asinakulibala ngayo INkanyamba uMateyu, eyafikelela kwinqanaba 5 kwisikali seSaffir-Simpson kwaye yabangela ukusweleka kwabantu abayi-1655, uninzi lwabo iseHaiti. Kwelinye icala lehlabathi, e-Asiya, iimvula ezinkulu kunye nezikhukula zachaphazela empuma nakumazantsi eli lizwekazi.
Nangona i-2016 kudala yadlula, kulo nyaka, nangaphandle kwefuthe lika-El Niño, iimeko zemozulu ezibi kakhulu ziya kuqhubeka ukwenzeka.
