Imininingwane emisha ikhishwe kwi-World Meteorological Organisation (WMO), ekhombisa ukuthi iminyaka emihlanu kusukela ngonyaka wezi-2011 kuya kowezi-2015 ezishisayo selokhu amazinga okushisa aqoshwa.
Umbiko, ushicilelwe ku- kukhulunywa ngokuguquka kwesimo sezulu okwenzeka eMorocco, uhlobanisa imisebenzi yabantu namazinga okushisa anyukayo. Ugcizelela ukuthi ezinye izifundo zithole ukuthi ukushisa okubaswayo kukhuphule amathuba okushisa okukhulu izikhathi eziyishumi noma ngaphezulu. Ababhali bacaphuna u-10 njengonyaka ozophinda wephule irekhodi lokushisa okuphezulu kakhulu emhlabeni.
Embikweni wayo wesimo sezulu womhlaba wonke kusuka ngo-2011 kuya ku-2015, i-WMO igcizelela ukuthi izinga lokushisa lomhlaba lalikhona 0,57 degrees ngaphezu kwesilinganiso, echazwa ngokuthi kusukela ngo-1961 nango-1990. Isikhathi seminyaka emihlanu kwakuyiso esinezinga lokushisa eliphakeme kakhulu kuwo wonke amazwekazi ngaphandle kwe-Afrika. Ngaleyo minyaka, amazinga okushisa ngaphezulu kweYurophu amaningi ayengaphezu kwe-1 degree ngaphezu kwesilinganiso esijwayelekile ngokuhamba kwesikhathi.
Ukwanda kwamazinga okushisa kuxhumene ngqo nokwanda kwamazinga kagesi abamba ukushisa emkhathini. Ngo-2015, i-WMO ithi ukugxilwa kwe-CO2 bekukhona Izingxenye ezingama-400 ngesigidi ngasinye futhi ikhule phakathi kuka-1,9ppm no-2,99ppm phakathi kuka-2011 no-2015.
Umbiko omusha kuqhakanjiswe isandla somuntu kulokho kukhishwa futhi wabaxhumanisa nezehlakalo zezulu ezimbi kakhulu. Le ncwadi icaphuna ukuthi ithonya elikhulu ekusetshenzisweni kwamafutha ezimbiwa kusimo sezulu kube sethubeni lokushisa okukhulu. Ezinye izifundo zithi amathuba akhuphuke izikhathi eziyishumi noma ngaphezulu.
Omunye umcimbi obalulekile uMMO akholelwa ukuthi yiwo kuxhunyaniswe namazinga okushisa ashisa kakhulu, kufaka phakathi isomiso eMpumalanga Afrika phakathi kuka-2010-2011 esidale abantu abalinganiselwa ku-258.000.
Amarekhodi unyaka nonyaka anakho ingozi eyengeziwe yemicimbi eyeqisayo njengokushaywa ukushisa, isomiso, ukurekhoda kwemvula, nezikhukhula.
