Stiven Hoking: te whenua e taea e taui ki te ao kōtuhi taua rite Venus

Ka taea e te whenua e taui ki ao kōtuhi rite Venus, ki moana kohua, ua waikawa, ki te kore e taea e te iwi te aukati i te panoni āhuarangi tina heke. kī tenei i roto i te uiuiraa tata ki ahupūngao Stiven Hoking. "He tata ki te wāhi pčpi i reira e riro warming ao tina heke matou. Hohenga Trump taea pana i te whenua ki te tuwhera, a ka waiho i te reira i te taua rite Venus, kei hea he 250 degrees te pāmahana toharite me te rangi hei utu o te ua makaka waikawa pungatara ", - ka mea a Stephen Hawking, hanga tohutoro ki te whakatau o Donald Trump ki te unu i US o te whakaaetanga āhuarangi Paris.

Ko te tauhohenga ki te kupu a Hawking

Heoi, ka mea te nuinga o te pūtaiao e te horopaki taua he faarahiraa pea, me te whakaari. Ina whakaritea ki Venus, he tawhiti rawa i te Rā te whenua, a no te mea o tona hanganga matū, e kore e waiho te reira i te huru mātotoru taua tito o te hauhā, kia e kore te pāmahana i runga i te whenua ka tae 250 degrees. Otiia i whakaae tohunga e te raruraru o te ia whānui o te huringa āhuarangi catastrophic kore i taea e atu akiaki ko. "I roto i tenei take, kua Hawking kua kōrero," - ka mea a Maykl Mann, he climatologist American i Pennsylvania State University. - Ko tata whenua i te ra i te Venus, na e kore e waiho te reira taea ki te ite i te kati kōtuhi taua i runga i te tauine taua, e te faaruru nei ona Venus, e ko i te ao e kore e kohuatia te moana i roto i te tikanga mo'oni. Heoi, he raruraru atu whānui e pā ki Hawking, i te mea e kia riro uninhabitable mō te ora te tangata i to tatou paraneta, ki te kore e tahuri te taata huringa āhuarangi kino he akiaki. "

ao hothouse

Venus - Ko te rua te ao i te ra tenei, a ko reira te ao kānapanapa i roto i te Pūnaha Solar. Ahakoa te ingoa reira i muri i te atua Roma o te aroha me te hiahia, e kore koe e hiahia ana ki te whakamahere i te haerenga whaiāipo ki tou hoa i runga i tenei ao i roto i te heke mai e tata ana. Ahakoa te meka e te rahi o Venus ko tata te rahi taua rite te whenua, a ka reira puta he mahara rite, te kore he reira rawa rerekē i te whenua ki tonu i te wai. Venus - Ko reira ano hoki te ao rawa i roto i te pūnaha solar, me pāmahana reira e taea tae 466 degrees. Ko te take mo te taua pāmahana he huru mātotoru me te matotoru o te hauhā, e kua kitea puta noa i te kapua o te waikawa pungatara. Nä, absorbs te huru nui atu te wera atu i kōhauhau o te whenua. I tua atu, he nui ofi ki te ra Venus, no te mea o nei absorbs reira nui atu radiation atu te whenua. Maha ngā puia kaha e tika tetahi atu tāpiritanga mō te ara kōeke Araha, e kua Venus. Ko te ariā taketake o te aha tipu Venus ki te reinga ahua takoto i roto i te meka i ko te ao i roto i te huringa rauemi koropiko e mutu. Planet absorbs atu radiation atu anapanapa, e tika ana ki I mahi ai hiri atu me te ake kohu wai i roto i te huru, i roto i te tahuri hua i te absorption o te rahinga ara nui o te wera me te warming tamau, i mohiotia te rite i te pānga kōtuhi. "Noa hoatu, riro Venus he" patunga wera ": ko tonu wera te ao, engari e kore e taea hauhautanga", - ka mea a Tyler Robinson, astrobiologist i te University o Washington.

He tauira e pea mo te whenua

Ahakoa tangohia te nuinga o te iwi mo homai te vai-o te āhuarangi o te whenua, Nōna te ao maha huringa faahiahia i roto i tona hītori, ko te 4.5 piriona tau te roa. I roto i oxygenation tiketike, i puta e pā ana ki 2.5 piriona tau ki muri, i whakapataritari cyanobacteria photosynthetic hua faahiahia te nui o te hāora i roto i te huru. A tawhio noa 650 miriona tau ki mua piri tino te ao, hoko kotahi te aanoraa a nui. A i roto i te wa o tuauri i runga i te pāmahana whenua ko te toharite o te 10 degrees runga ake i nei, no te mea he taonga i roto i te te hauhā tonu te kōhauhau. Kua meinga he tukunga waro nui maha moa i roto i te mua, mo te tauira, te ngaro i te mutunga o te wā Permian, e pā ana ki 252 miriona tau ki muri, ka ora moana e pā ana ki 95 ōrau mate e tika ana ki te hāora o te moana.

e kore e Earth mamae te whakarau o Venus

Ko reira reira e kore he kia whakaaro te horopaki o te kino makariri nui. Heoi, e whakapono tonu te nuinga o ngā tohunga e te horopaki taua he tino pea. I roto i te ariā, te tukanga taua, i whakarewahia ki runga ki Venus, taea tupu i roto i te ao, engari ko te reira ia tapao e ka tangohia tenei tukanga rau o miriona o nga tau. Na rite tonu ki te nuinga o ngā tohunga. Ano, ko te tūponotanga e ka kohuatia moana o Papatūānuku i roto i te ara ano rite te moana i runga i Venus ko te tino iti.

Ko tiakina te whenua?

Ko te meka e tiakina te te whenua i radiation solar ko te huru e te mea tino rerekē i te huru o Venus. "Ko e pā ana ki te rau nga wa nui me apiapi atu te kōhauhau o te whenua te huru o Venus, a ko te kupu ngā reira tata katoa o te hauhā," - ka mea a Robinson. No te whakarite, te huru o te whenua ngā nuinga o te hauota rāpoi, me te hāora, ka kiia 0.04 anake ōrau mō te hauhā.

kua ite Whenua te kino

Te kore te huru mātotoru o te hauhā me te horopeta atu o te radiation solar te tūponotanga e ka tupu te tauira e taua i roto i te ao, me e he tino iti Venus. Kahore he anaanatae kouma o taua haurehu kati kōtuhi i roto i nga meka e kua mohiotia ki te iwi i tenei ra. I tua atu, i roto i te mua i runga i te whenua i mahana tikanga makariri, hei tauira, i roto i te taitahi Eocene (i waenganui i 56 me 34 miriona tau ki mua). I taua wa, ko e toru nga wa ki runga ake i tenei te ihirangi hauhā i roto i te huru. Ahakoa, ki te whakaaro koe te heke mai o nga waka, rererangi, me te whāhauhau katoa, e kore e kore haurangi āhuarangi e taea ki te whakaatu i te taumata rite o te hauhā i te huru.

poto kino o te hōtuhi

e kore e kati kōtuhi whakakeke tenei ra tohu i te tino riri ki te ao. Ko, o te akoranga, i reira he tonu te riri o te auru huna āta. Ka taea e Dr. kino whakaaroa he otinga engineering, rite ki te hunga whakaarohia mō te tua ki te terraform Mars, engari me kia nui te tauine o taua mahi. Ka Me koe fluorocarbons, kia ka whai Dr. kino ki te whakatū i te haapa'oraa ao, whakatapua ki te whakamahi tapu o te rehu me te deodorant. Otiia tenei te haere mai te raruraru: i roto i te mua i roto i te tahi mau hua kiritaki aerosol whakamahia fluorocarbons, Heoi, tenei whakauru kua rāhuitia mō te whakamahi i roto i te mutunga o nga fitungofulú.

Ko taea Climate kino

Heoi, e kore e hiahia ana i te ao ki te riro te rua o nga Venus, kia riro te reira ere mō te ora te tangata. Paris Whakaaetanga te hokonga o te pupuri e painaina ana ki iti iho i te rua degrees runga ake pāmahana mua-ahumahi. Ko kia ara tenei taumata tonu hoki o te wā, he wā roa arahi ki huringa tina heke e kua tīmata kē. Ka taea e ēnei rerekētanga o te huarere meinga kino catastrophic ki rauwiringa kaiao teretetiera, me te ahuwhenua.
