Umuyobozi mukuru w’Itsinda rirwanya umwuka wa Karubone (anti-carbon group E3G), Tom Burke, yabwiye Al Jazeera ko ikibazo kiri kwiyongera kurusha uko abantu babitekereza.

Igiteye impungenge ni uko nta bimenyetso bigaragara byo kugera ku ntego yo gutangira kugabanyuka kw’ibyo byuka byoherezwa mu kirere.

Amasezerano y’i Paris yo mu 2015 agaragaza ko ibihugu byiyemeje gushyiraho ingamba zo kugabanya izamuka ry’ubushyuhe kugeza nibura kuri 20C cyangwa 1.50C kuko aribyo bishobora guhagarika izamuka ry’ubushyuhe mu buryo buhamye.

Gusa ubwo bushakashatsi bwatanze umuburo uvuga ko nubwo buri gihugu cyagera kuri iyo ntego, ubushyuhe buzazamuka kuva kuri 2.90C kugera kuri 3.40C. Kandi nabyo kugira ngo bishoboke ni uko Ibihugu byakuba gatatu umuvuduko biri kugenderaho ubu bishaka kugera kuri 1.50C.
