Kera cyane, imigabane yose yibanze mu gihugu kimwe yitwa Pangea. Pangea yatandukanijwe hashize imyaka 200, ibice byacyo byagendaga kuri plaque ya tectonike, ariko ntabwo ari ibihe byose. Umugabane wongeye kongera guhura mu gihe cya kure. Ubushakashatsi bushya, buzashyikirizwa ku ya 8 Ukuboza ku cyapa kuri interineti ku nama y'Abanyamerika y'Abanyamerika, yerekana ko aho ejo hazaza habo hashobora kugira ingaruka ku binyuranye bishobora kugira ingaruka ku busa ku isi no guharanira ikirere. Izivumbuzi nazo ni ngombwa mugushakisha ubuzima ku yindi mibumbe.
Ubushakashatsi bwatanzwe kugirango butangwe ni uwambere mu kwerekana ikirere cyurugero rwa kure.
Abahanga ntabwo bazi neza icyo ikinyamakuru gikurikira kizasa cyangwa aho kizaba giherereye. Ikintu kimwe gishoboka ni uko mumyaka miriyoni 200, imigabane yose usibye Antaragitika yashoboraga kwinjira hafi ya pole y'Amajyaruguru kugirango ikore Arumeniya ya supercontinent. Ikindi gishoboka ni uko "Aurica" ​​yashoboraga gushira ku migabane yose yahuye na ekwateri mu gihe cy'imyaka igera kuri miliyoni 250.
Ukuntu ibihugu bya supercontinent Auro (hejuru) na Amasiya bitangwa. Inshingano zizaza zerekanwa kumugezi, kugereranwa hamwe numugabane wubu. Inguzanyo yishusho: Inzira et al. 2020
Mu bushakashatsi bushya, abashakashatsi bakoresheje icyitegererezo cya 3D ku isi yose kugira ngo binge icyitegererezo uburyo ibyo bikoresho byombi byo ku butaka byagira ingaruka ku miterere y'ikirere ku isi. Ubushakashatsi bwayobowe n'imiziki ya Michael, umuhanga mu bya fiziki mu kigo cy'amadini ya Nasa kubera amasomo yo mu kirere, igice cy'ikigo cy'isi cya Columbia.
Iyi kipe yasanze Amasya na Aurika bigira ingaruka mubihe bitandukanye no guhindura ikariso yo mu kirere no mu nyanja. Niba imigabane yose yahujwe hafi ya ekwateri muri scenator ya Aurica, isi irashobora kurangiza ubushyuhe bwa 3 ° C.
Muri Scenario ya Amasaya, kubura ubutaka hagati yinkingi byahungabanya umukandara w'inyanja, ubu utwara ubushyuhe muri ekwateri kugera ku nkingi kubera kwegeranya ubutaka bukikije inkingi. Nkigisubizo, inkingi zizakonje kandi zipfukirana mu rubura umwaka wose. Urubura rwose rugaragaza ubushyuhe mumwanya.
Hamwe na Amasya, "kugwa cyane." Inzira yabisobanuye. "Ufite impapuro za rubura kandi ubona ibitekerezo bya albedo byiza cyane bikunda gukonja umubumbe."
Usibye ubushyuhe bukonje, uburyo bwo mu nyanja bwavuze ko bwo mu nyanja bushobora kuba munsi ya Scenario ya Amasaya, amazi menshi yagwa mu mpapuro, kandi ibintu bya shelegi bishobora gusobanura ko nta butaka bwinshi bwo guhinga imyaka.
Ku rundi ruhande, Tweriko, birashoboka kurushaho ku mucanga, aravuga. Isi yegereye ekwateri yakwinjiza izuba rikabije, kandi ntihazabaho ingofero ya ice ya polar yerekana ubushyuhe mu kirere cy'isi, bityo ubushyuhe bw'isi bwaba burenze.
Mu gihe inzira igereranya inkombe za Aurica kuri parast ya paradizo ya Berezile, "irashobora kubona imbere mu gihugu cyumye." Byaba byinshi mugihugu bibereye ubuhinzi bizaterwa no gukwirakwiza ibiyaga nubwoko bwimvura bahabwa-ibisobanuro ntabwo bikubiye muri iki kiganiro, ariko bushobora gutegurwa ejo hazaza.
Ikwirakwizwa rya shelegi na barafu mu gihe cy'itumba no mu cyi i Airuka (ibumoso) na Amasya. Inguzanyo yishusho: Inzira et al. 2020
Icyitegererezo cyerekana ko 60 ku ijana by'akarere ka Amazone ari byiza amazi meza, ugereranije na 99.8 ku ijana by'akarere ka orica - kuvumbura bishobora gufasha mu gushakisha ubuzima ku bundi mibumbe. Kimwe mu bintu by'ingenzi bireba iyo ushakisha isi ishobora kuba ishobora kuba ishobora kuba niba amazi meza ashobora kubaho ku isi. Mugihe utanga kwerekana izindi isi, bakunda kwigana imirambo itwikiriwe rwose ninyanja cyangwa bafite imiterere isa nisi yiki gihe. Ariko, ubushakashatsi bushya bwerekana ko ari ngombwa gusuzuma ahantu hashingiye ku butaka mugihe usuzumye niba ubushyuhe bugwa muri "kamere" hagati yo gukonjesha no guteka.
Nubwo bishobora gufata abahanga imyaka icumi cyangwa irenga kugirango umenye ikwirakwizwa ryukuri nubumbe bwimibumbe mubindi bikorwa byinyenyeri, abashakashatsi bizeye ko bazagira intebe nini yubutaka ninyanja kugirango bibone igereranya rishobora kubaha. imibumbe. isi ituranye.

Mwaramutse Sarah. Nongeye. Yoo, ikibara kimeze nkigihe isi ihinduka kandi ishaje yo mu nyanja ishaje ifunga kandi ifunguye. Ibi bigomba guhinduka kuko nizera ko umuyaga ninyanja uzahinduka, wongeyeho inzego za geologiya zizahita. Isahani y'Abanyamerika y'Amajyaruguru iragenda vuba mu majyepfo y'uburengerazuba. Ikibanza cya mbere cyo muri Afurika kibujije Uburayi, muri Turukiya hari umutingito mwinshi, Ubugereki n'Ubutaliyani n'Ubutaliyani. Bizashimisha kubona icyerekezo ibirwa byo mu Bwongereza gigenda (Irlande ikomoka muri pasifika yepfo mu karere k'inyanja. Nibyo kororero k'ibipaji
