Ntabwo isi idukeneye, ahubwo dukeneye isi.

Nyuma yizuba ryinshi ryo mu 2021 hamwe nubushyuhe bwo hejuru, igice cy’amajyaruguru cyatangije imbeho ikonje, kandi hagwa urubura rwinshi, ndetse no mu butayu bwa Sahara, hamwe mu hantu hashyushye cyane ku isi.Ku rundi ruhande, igice cyo mu majyepfo cyatangiye ubushyuhe bukabije, ubushyuhe bugera kuri 50 ° C mu Burengerazuba bwa Ositaraliya, kandi ibibarafu binini byo muri Antaragitika byashonga.None byagenze bite ku isi?Kuki abahanga bavuga ko kuzimangana kwa gatandatu bishobora kuba byaraje?
Nkubutayu bunini kwisi, ikirere cyubutayu bwa Sahara cyumye cyane kandi kirashyushye.Kimwe cya kabiri cyakarere kakira imvura itageze kuri 25mm yumwaka, hamwe na hamwe usanga nta mvura igwa mumyaka myinshi.Ubushyuhe buri mwaka muri kariya karere buri hejuru ya 30 and, kandi impuzandengo yubushyuhe bwo mu cyi irashobora kurenga 40 ℃ mumezi menshi akurikirana, kandi ubushyuhe bwo hejuru bwanditseho ni hejuru ya 58 ℃.

Ariko muri kariya gace gashyushye cyane kandi kakakaye, ni gake hagwa urubura muriyi mezi y'itumba.Umujyi muto wa Ain Sefra, uherereye mu majyaruguru y'ubutayu bwa Sahara, urubura muri Mutarama uyu mwaka.Urubura rwatwikiriye ubutayu bwa zahabu.Amabara yombi yari avanze, kandi ibyabaye byari umwihariko.
Igihe urubura rwaguye, ubushyuhe bwo mumujyi bwaragabanutse kugera kuri -2 ° C, ubukonje bwa dogere nkeya ugereranije n'ubushyuhe bwo mu gihe cyizuba cyabanje.Umujyi wari waraguye inshuro enye mu myaka 42 mbere yacyo, mbere ya 1979 na bitatu bya nyuma mu myaka itandatu ishize.

Urubura mu butayu ni gake cyane, nubwo ubutayu bukonje cyane mu gihe cy'itumba kandi ubushyuhe bushobora kugabanuka munsi ya zeru, ariko ubutayu bwumutse cyane, ubusanzwe nta mazi ahagije mu kirere, kandi hari imvura nkeya kandi shelegi.Urubura rwo mu butayu bwa Sahara rwibutsa abantu imihindagurikire y’ikirere ku isi.
Umuhanga mu bumenyi bw'ikirere mu Burusiya Roman Vilfan yavuze ko urubura mu butayu bwa Sahara, imvura ikonje muri Amerika ya Ruguru, ikirere gishyushye cyane mu Burusiya n'Uburayi, n'imvura nyinshi yateje imyuzure mu Burayi bw'i Burengerazuba.Kugaragara kw'ibi bihe bidasanzwe bigenda byiyongera, kandi impamvu yabyo ni imihindagurikire y’ikirere iterwa n'ubushyuhe bukabije ku isi.

Mu majyepfo yisi, ingaruka zubushyuhe bwisi zirashobora kugaragara neza.Mu gihe igice cyo mu majyaruguru cyari kigikomeza guhura n’imbeho ikonje, igice cy’amajyepfo cyahuye n’ubushyuhe, ubushyuhe burenga 40 ° C mu bice byinshi byo muri Amerika yepfo.Umujyi wa Onslow mu burengerazuba bwa Ositaraliya wanditseho ubushyuhe bwo hejuru bwa 50.7 ℃, uca amateka y’ubushyuhe bwo hejuru mu gice cy’amajyepfo.
Ubushyuhe bukabije bukabije mu gice cyamajyepfo bufitanye isano ningaruka zubushuhe.Mu ci rishushe, ryumye kandi ridafite umuyaga, umwuka ushyushye uzamuka ku butaka ntushobora gukwirakwira, ariko ugabanywa hasi n’umuvuduko mwinshi w’ikirere cy’isi, bigatuma umwuka urushaho gushyuha.Ubushyuhe bukabije muri Amerika ya ruguru muri 2021 nabwo buterwa ningaruka zubushuhe.

Mu majyepfo y’isi, ibintu ntabwo ari byiza.Muri 2017, ikibara kinini kinini gifite A-68 cyavuye mu kiraro cya Larsen-C muri Antaragitika.Ubuso bwacyo bushobora kugera kuri kilometero kare 5.800, hafi yakarere ka Shanghai.
Urubura rumaze kumeneka, rwagiye mu nyanja y'Amajyepfo.Yanyuze intera ya kilometero 4000 mumwaka nigice.Muri kiriya gihe, urubura rwakomeje gushonga, rusohora toni zigera kuri miliyari 152 z'amazi meza, ibyo bikaba bihwanye n'ububiko bwo mu biyaga 10,600.

Kubera ubushyuhe bw’isi, gushonga kw’amajyaruguru n’amajyepfo, bifunze amazi menshi, birihuta, bigatuma inyanja ikomeza kwiyongera.Ntabwo aribyo gusa, ahubwo gushyushya amazi yinyanja nabyo bitera kwaguka kwinshi, bigatuma inyanja nini.Abahanga mu bya siyansi bavuga ko ubu inyanja y’isi iri hejuru ya santimetero 16 kugeza kuri 21 ugereranije n’uko byari bimeze mu myaka 100 ishize, kuri ubu ikaba izamuka ku kigero cya milimetero 3,6 ku mwaka.Mugihe inyanja ikomeje kwiyongera, izakomeza kwangiza ibirwa hamwe n’ahantu hahanamye cyane ku nkombe z’inyanja, bibangamira ubuzima bw’abantu.
Ibikorwa byabantu ntabwo byibasiye gusa cyangwa ngo bisenye aho inyamaswa n’ibimera bituye, ahubwo binasohora imyuka myinshi ya dioxyde de carbone, metani n’indi myuka ya parike, bigatuma ubushyuhe bw’isi bwiyongera, bigatuma ihindagurika ry’ikirere ndetse n’ikirere gikabije bikaba bishoboka. Kuri.

Bigereranijwe ko kuri ubu ku isi hari amoko agera kuri miliyoni 10.Ariko mu binyejana byashize, amoko agera ku 200.000 yarazimye.Ubushakashatsi bwerekana ko igipimo cy’ibinyabuzima kizimangana ku isi cyihuta kuruta igipimo mpuzandengo mu mateka y’isi, kandi abahanga mu bya siyansi bemeza ko kuzimangana kwa gatandatu bishobora kuba byaraje.
Mu myaka miriyoni amagana yashize kwisi, ibintu byinshi byazimye, binini na bito, harimo ibintu bitanu bikabije bikabije, bituma amoko menshi abura ku isi.Impamvu zitera amoko yabanjirije kuzimangana zose zaturutse muri kamere, naho iya gatandatu ikekwa ko ari yo nyirabayazana w'abantu.Ubumuntu bugomba gukora niba tudashaka kuzimangana nkuko 99% byubwoko bwisi bwigeze kubikora.
