Ukunyuka kwamaqondo obushushu ehlabathini kubangela iingxaki ezininzi kwihlabathi jikelele. Iziganeko zemozulu, eziquka imbalela, amaza obushushu kunye nezikhukhula ziya ziba qatha.
Ngoku, ngenxa yophando olwenziwa liqela lezenzululwazi elivela kwiZiko loPhando kwiZiphumo zoTshintsho lweMozulu ePotsdam (eJamani), epapashwe kwijenali 'Uhlobo lweTshintsho lwemozulu', siyayazi loo nto Ukunyuka kwe-0,5 degrees celsius kwanele ukwenza iimeko zemozulu ezibi kakhulu zibe nde kwaye zibe namandla ngakumbi.
Abaphandi bahlalutya amaqondo obushushu eMhlabeni kwiminyaka emibini engama-20: ukusuka ku-1960 ukuya ku-1979, kwaye ukusuka ku-1991 ukuya ku-2010, kwaye bakwazi ukufumanisa ukuba ukonyuka kwe-0,5ºC kuphela kwakwanele ukuba iimeko zemozulu ezibi kakhulu zenzeke. Umzekelo, imvula egqithileyo ikhule phantse nge-10% kwikota yesijikelezi-langangexesha amaza obushushu ande ngomyinge weveki kwisiqingatha semimandla yomhlaba.
Olu tshintsho ngaphaya kokuguquguquka kwendalo. Ukusetyenziswa okuqhubekayo kwamafutha efosili, kunye nokungcoliswa komhlaba, ulwandle nomoya, kunegalelo ekwenzeni izinto zibe mbi ngakumbi, kangangokuba, phantse ngaphandle kokuqaphela, ukuba siqhubeka ngolu hlobo siya kubeka ubomi bethu engozini. Enyanisweni, iingcali ngokwazo ziqikelela oko siya kuba nesivuno esibi kakhulu, ukuncitshiswa konikezelo lwamanzi okusela kunye namaza obushushu obugqithisileyo.
Kwaye ayitsho loo nto Izixhobo ze-coral, kunye nabo bonke abemi abazikhuselayo kuzo, zisongelwa kakhulu. Ulwandle olushushu ngakumbi noluneasidi ngakumbi alunakuba likhaya leekorale, ekubeni zifuna ikalika ukuze zenzeke.
Ukuba asenzi nto, isijikelezi-langa esinguMhlaba kumashumi eminyaka nje ambalwa siya kwahluka kakhulu kuleyo siyaziyo namhlanje.
