isipiliyoni semvelo | Umndeni webhere elimhlophe ohambeni

Umndeni webhere elimhlophe ohambeni okokuqala ngqa

Ibhere elingumama newundlu lalo bathatha uhambo lwabo lokuqala bendawonye eqhweni lasolwandle.

“Indawo esezindaweni ezishisayo yamabhere angu-25 000 asele ancibilika ngaphansi kwezidladla zawo.

Ingabe umhlaseli omkhulu kunawo wonke usenalo ikusasa?

Yilokho ososayensi uSybille Klenzendorf noDirk Notz abafuna ukukuthola e-Arctic.

Ngedokhumentari ethi "Polar Bears on the Run", ababhali u-Anja-Brenda Kindler no-Tanja Dammertz baphelezela abacwaningi baye ezweni elikude, elishintshayo.

Ukufuna amathuba enkosi yesikhathi esisodwa yase-Arctic nakho kuveza imininingwane ngomthelela wokushintsha kwesimo sezulu emhlabeni. Menschen.

Die isikhathi izinxushunxushu: Uma ukufudumala kwembulunga yonke kungayekwa ngokushesha, amanye amabhere asezindaweni ezishisayo azokwehla ngamaphesenti angu-20 eminyakeni engu-30 kuya kwengu-60.

Yilokho ososayensi abafana nomcwaningi wesimo sezulu u-Dirk Notz kanye nesazi sezinto eziphilayo zasendle uSybille Klenzendorf.

ohambweni lwakhe locwaningo oLwandle iBeaufort enyakatho ekude ye-Alaska, okuyikhaya lelinye lamabhere amhlophe abaluleke kakhulu emhlabeni, i-Klenzendorf iphenya inani nesimo samabhere amhlophe..

Eminyakeni engu-1500 edlule, abangu-900 XNUMX babehlala lapha, manje sebengu-XNUMX kuphela.

Futhi lezi zilwane zinobufakazi bokungondleki.

U-Dirk Notz we-Max Planck Institute for Meteorology e-Hamburg ufuna ukuthola ukuthi kubaluleke ngani ukufudumala kwembulunga ngezinga leqhwa olwandle.

Phakathi nohambo lwakhe lwaseSpitsbergen uthola amanzi, lapho iqhwa lasolwandle kufanele libe khona. Neqhwa elisekhona liya lincipha futhi lincipha.

Kaningi uhlangana nezilwane ezilambile lapho.

Izinguquko ku pakisha iqhwa ngokusobala athuthuka ngokushesha kangangokuthi amabhere asezindaweni ezisenyakatho akanaso isikhathi sokuzivumelanisa nezimo ezishintshile.

Ukusinda kwazo kuncike eqhweni lasolwandle eliqinile, njengoba kuwukuphela kwendawo ezingazingela kuyo.

“Enhlokodolobha yebhere elimhlophe”, iChurchill yaseCanada, imidondoshiya emhlophe iya ngokuya izulazula ezindaweni zokulahla imfucumfucu ukuze ithole ukudla.

Lapho befuna ukudla, bangena ezindaweni zokuhlala - hhayi ngaphandle kwengozi kubantu abahlala lapho.

Umcwaningi wesimo sezulu uNotz uqinisekile: Ukufudumala kwembulunga yonke okwenziwe abantu kuyimbangela yokuhlehla kweqhwa.

Isiphetho sekota yokugcina yeqhwa lasolwandle i-Arctic kanye nekusasa lamabhere ase-polar kusezandleni zethu.”

Ibhere elimhlophe lihlala limhlophe - isipiliyoni semvelo | Umndeni webhere elimhlophe ohambeni

Limhlophe kangakanani ibhere elimhlophe?

Eminyakeni embalwa nje, ibhere elimhlophe seliwuphawu lokulwa nokushintsha kwesimo sezulu.

Kufanekisela ushintsho lwezwe, kodwa empeleni isimo sinje izilwane inkimbinkimbi kakhulu kunaleyo evezwa kwabezindaba.

Amadokhumenti ahlinzeka ngemininingwane yendlela yokuphila esengozini yamabhere amhlophe.

Ukubuka amabhere asezindaweni ezine zonyaka kubonisa ukuthi akukhona nje kuphela ukuziphatha kwezilwane kodwa nezici zazo eziphilayo ezingashintsha.

Ukuze sifinyelele ekujuleni kwalesi simo, ukufana nomehluko phakathi kwamabhere ase-polar nabazala bawo, amabhere ansundu, ukuze ihlolwe kabanzi.

Lezi zinhlobo ezimbili zihlobene emlandweni wokuziphendukela kwemvelo, futhi zombili zibonakala ngokuguquguquka okukhulu.

Ukuqhathanisa phakathi kwabo kubonisa ukuthi kunamandla kangakanani Evolution izinhlobo zezilwane kuncike endaweni ezihlala kuzo kanye nemithombo yazo.

I-documentary ikuyisa emhlabeni omangalisayo wamabhere amhlophe nansundu, kusukela e-Finland kuya e-Kamchatka, e-Hudson Bay nase-Svalbard kuya e-British Columbia.

Ihlengethwa lidlala ngamaringi omoya

Kwenziwa ubungane obusha

Izinja zisiza izingane

Indlovu idweba isithombe ngomboko wayo
