Biteganijwe ko ubushyuhe bw’isi buzamuka ku rwego rw’amateka mu myaka itanu iri imbere kubera ko imyuka ihumanya ikirere yatuma habaho ibihe bibi by’ikirere, nk’uko umuburo mushya w’umuryango w’abibumbye wita ku bumenyi bw’ikirere ubitangaza.
Imyaka itari mike ndetse n’ubushyuhe burenze urugero butera Isi kurenza urugero rwica, umuriro kandi utorohewe, nkuko bibiri mubigo bikuru by’ikirere bibitangaza.
Hari amahirwe 80% isi izaca ku rutonde rw’ubushyuhe buri mwaka mu myaka itanu iri imbere, ndetse birashoboka cyane ko isi izongera kurenga igipimo cy’ubushyuhe mpuzamahanga cyashyizweho mu myaka 10 ishize, nk’uko bivugwa n’imyaka itanu yashyizwe ahagaragara ku wa gatatu n’umuryango w’ubumenyi bw’ikirere (WMO) hamwe n’ibiro by’ubumenyi bw’ikirere mu Bwongereza.
Ku nshuro ya mbere hari amahirwe nubwo yaba make ko mbere y’imyaka icumi ishize, ubushyuhe bw’umwaka ku isi buzarasa ku ntego y’ikirere cy’i Paris cyo kugabanya ubushyuhe bugera kuri dogere selisiyusi 1.5 kandi bugatera dogere selisiyusi 2 ziteye ubwoba kuva mu myaka ya za 1800 rwagati, ibyo bigo byombi byavuze.
Hariho amahirwe 86% yuko umwe mumyaka itanu iri imbere uzatsinda dogere 1.5 naho amahirwe 70% yuko imyaka itanu muri rusange izagereranya kurenza iyo ntambwe yisi yose.
Isi ya dogere 1.4 ishyushye kuruta muri 1850
Ibiteganijwe biva mubisobanuro birenga 200 ukoresheje amashusho ya mudasobwa ikoreshwa na centre 10 z’ubumenyi bw’isi.
Imyaka icumi ishize, amakipe amwe yasanze hari amahirwe nkaya ya kure hafi 1% ko umwe mu myaka iri imbere uzarenga iyo ntera ya dogere 1.5 hanyuma bikabera umwaka ushize. Uyu mwaka, dogere selisiyusi 2 hejuru y’umwaka wabanjirije inganda yinjira muburinganire muburyo busa. Impamyabumenyi ebyiri z’ubushyuhe ni urwego rwa kabiri, imwe ifatwa nkaho idashobora gucika, yashyizweho n’amasezerano y’i Paris 2015.
Mu buryo bwa tekiniki, nubwo 2024 yari ifite ubushyuhe bwa dogere selisiyusi 1.5 ugereranije n’ibihe byabanjirije inganda, imbibi z’amasezerano y’ikirere ya Paris ni iy’imyaka 20, ntabwo rero yarenze.
Umuyobozi ushinzwe serivisi z’ikirere muri WMO, Chris Hewitt, yagereranije ko mu myaka 10 ishize no guteganya imyaka 10 iri imbere, ubu isi ishobora kuba ifite ubushyuhe bwa dogere selisiyusi 1,4 kuva hagati ya 1800.
Impuguke zavuze ko urubura muri Arctique ruzakomeza gushyuha vuba inshuro 3,5 kurusha isi yose ruzashonga kandi inyanja izamuka vuba.
Abahanga bavuga ko ikunda kubaho ni uko ubushyuhe bw’isi buzamuka nko kugendera kuri escalator, hamwe n’ikirere cy’igihe gito kandi gisanzwe cya El Niño gikora nko gusimbuka hejuru cyangwa hejuru kuri iyo escalator.
Ariko vuba aha, nyuma yo gusimbuka kuva El Niño, wongeyeho ubushyuhe kw’isi, umubumbe ntusubira inyuma cyane, niba ari byose.
