Funda isimo kangcono. Kuyini ezahlukene okushisa, okuyinto amarekhodi lokushisa futhi kungakanani kusala khona izinguzunga zeqhwa?

Zonke isikhathi sizwa ku-TV ukuthi siyeza ukufudumala kwembulunga yonke, izinguzunga zeqhwa iyogcwala amanzi, likhuphuka izinga lokushisa futhi amanzi iyokhukhula ingxenye enkulu ezweni. Futhi zonke iphutha kwamagesi abamba ukushisa emkhathini, okuyinto ibulala ungqimba lwe-ozone, okuyinto kusivikela ilanga.

Ososayensi namanje bebaphikisana ngani futhi angeke eze isixazululo ezivamile. Kunabantu labo ukusho ukuthi ngaso sonke isikhathi kule mbulunga enguMhlaba siyashintsha izinga lokushisa isilinganiso emoyeni. Lokhu kuchaza isikhathi glacial, kanye nezikhathi isomiso esinzima.

Ngemva kokufunda lesi sihloko, ungaphendula kalula umbuzo uyini amplitude we lokushisa, ngeke ukwazi amaqiniso athakazelisayo kanye namarekhodi lokushisa kule planethi yethu. Futhi asendabeni ezinye izibikezelo ososayensi amashumi eminyaka ezayo.

Kuyini ezahlukene okushisa

Ngokufunda sezulu emhlabeni, odinga ukukwazi ezinye imiqondo ezisetshenziswa ababikezeli bezulu nabanye ososayensi ehilelekile ukuhlaziywa izenzakalo sezulu.

Sizokwenza baqonde ukuthi uhla okushisa - a ukuguquguquka kusho lokushisa for ethile yesikhathi. izinsuku, izinyanga neminyaka zivame ukusetshenziswa. Ukusebenzisa leli thuluzi, ososayensi bazama ukuthola zesimo sezulu emhlabeni.

Ukukhuluma ngokuthi liyini amplitude we lokushisa, izibonelo ezilandelayo ukuzwakala. Kukhona umuzana Yakutsk esifundeni, okuthiwa Ojmjakon. Ebusika kukhona abandayo kakhulu, futhi ehlobo sezulu ufudumele.

Ngo-January, nezinga lokushisa at -46 degrees Celsius, futhi ngo-July - mayelana 14.5 degrees. Lokho umehluko phakathi ehlobo futhi lokushisa ubusika amaphuzu mayelana 60. Ngesikhathi esifanayo, banikezwe minimum futhi esiphezulu, okuyinto eqondiswa ososayensi, lo mehluko ifinyelela 98 degrees (-65.4 ngo-1973 futhi 32,6 ngo-1989). Ojwayelekile nje wase-esinye isifunda ukusinda ezifana lokushisa ekushintshashintsheni kulula kakhulu.

Amarekhodi lokushisa Global

Cabangela impumelelo sezulu ambalwa, okuyinto zalotshwa ezingxenyeni ezihlukahlukene zomhlaba.

Hard ukukholelwa, kodwa e-Antarctica kwi "Vostok" esiteshini ngo-1983, izinga lokushisa safinyelela -82,3 degrees Celsius. Ngisho owaziwa anti-nqabela, okuyinto ngokuvamile sisetshenziswa mikhankaso yesimanje ukuze ngokubona izinguzunga zeqhwa, iqala ukuba iqhwa at 40-50 amagremu. ngaphansi kwezingaqhwa.

Ngalesi lokushisa ngeke usebenze 99% yobuciko yesimanje. Ngisho izintambo ezivamile kweso iqhwa futhi abhidlize izingcezu. Ngakho umhlaba uzungeza emzileni, ngokuvumelana ososayensi, lishise ukuba 4 degrees ngenhla zero. Ngakho zikhona izindawo emkhathini lapho ukufudumala kunomhlaba.

Russia loke nje lidume ngokuthunga obubandayo enyakatho ngoba. Ngo Ust-Shchugorev amazinga okubanda ebusika ukufinyelela lokususa 55 degrees.

ukushisa babulawa

Iningi lokushisa eliphezulu wake phansi ngumuntu, kuyinto 57,8 degrees. It kwaphawuleka eLibya, edolobheni lase-El-Aziz. Okwesibili kungenzeka wazi Ukufa Valley e-USA. Ngo-1913, izinga lokushisa kwe-56,7 degrees sabhalwa khona. A Juni 21, 1942 edolobheni Israeli ka Tirat Swee lokushisa eliphezulu kunawo kwaba 53.9 degrees.

Kuyaphawuleka ukuthi amaprotheni iqala phinda at lokushisa 46 ngenhla zero. Okungukuthi, ungakwazi Fry amaqanda ngqo phezu kwendawo egandaywe ngamatshe, okuyinto ukufuthelana kancane okungaphezu komoya.

benza Ngakho unabantu abambalwa lokhu iningi esiGodini Ukufa, owendlala izithombe namavidiyo ku-amanethiwekhi omphakathi. Kamuva, ukuze kubuyiselwe ukuthula, iziphathimandla wakhipha umthetho ekuvimbeleni ngendlela ukupheka ukudla.

Coming amarekhodi entsha

Izangoma zezulu emhlabeni wonke umlando ukwanda nezinga lokushisa emhlabeni. Futhi lokhu kuqinisekiswa amaqiniso angempela. Kukhona izifundo lososayensi Japanese ababonisa Ukwanda okungavamile nezinga lokushisa past 120 iminyaka. Ngokombono wabo, iletha umonakalo enkulu yomsebenzi womuntu.

Ngokusebenzisa imisebenzi yayo, umuntu izikhathi eziningana kwandisa amandla Isivuvu, ngaleyo ndlela nokucupha engelapheki ukuguquka kwesimo sezulu emhlabeni. Carbon dioxide - ngumbhubhisi eyinhloko ungqimba lwe-ozone.

Uma abantu akagcini futhi ngeke silinganisela ingqikithi kwekhabhoni izinto eziyingozi emkhathini, ematfuba eduze ukuthi phakathi namashumi ambalwa eminyaka, Umdwebo "I Amphibian Man" ngeke kubonakale eqanjiwe. Ukwanda lokushisa emhlabeni by 3 kuphela degrees kuholele ephelele ukuncibilika kwezinguzunga zeqhwa okwakungokokuqala ngqá.

Uma lokhu kwenzeka, khona-ke cishe 80% yonke le mbulunga kuyoba ngaphansi kwamanzi, lapho sizothinta izimpilo zabo bonke abantu. Ngokusho kochwepheshe, lokhu kuzokwenzeka kuphela ngemuva ayizinkulungwane. 2 Iminyaka.
