Ukubikezela kokuphela kwezwe kuyathakazelisa kubo bonke, ngakho-ke umsebenzi webaprofethi abaningi kanye nabafundi kuningi ngokwanele! Futhi ngokucabangela ukuthi ngenhlanhla, lo mbulali ongenakuqondakalayo-umbulali uNibiru akazange ahlangabezane noMhlaba ngoSepthemba 23, uSuku Lokwahlulela luphinde ludluliselwe osukwini olusabekayo olusabekayo ...
Ngakho-ke, namuhla, isazi se-geophysicist evela eMassachusetts University of Technology, uProfesa Daniel Rothman, wazama ukuthola isikhathi sengozi engenakugwemeka emhlabeni. Kulesi simo, usosayensi akazange nje aziqagele, kodwa abuye athole isakhelo sembalo, ngokusho kokubalwa kokuphela kokuphela komhlaba emhlabeni wonke ekupheleni kwekhulu lama-XXI!
Kodwa uma ucabanga ukuthi lolu suku luvela esikhathini esizayo kakhulu, khona-ke uyiphutha - abazukulu bethu bayothola! Futhi konke kuzokwenzeka ngenxa yezinguquko ezingenakuguqulwa emjikelezweni wombulunga womhlaba wonke obangelwa ukukhishwa kwe-anthropogenic kaboni dioxide.
Esebenzisa "i-math" yakhe, uRothman wahlaziya zonke izinguquko emjikelezweni we-geochemical of carbon eminyakeni engama-450 edlule. Kubonakala ukuthi phakathi nalesi sikhathi esikhulu, kwakukhona amahlanu amakhulu kakhulu ekuqothulweni okukhulu kwamazwe amakhulu, kuhlanganise nesabekayo kakhulu - ukuqothulwa okukhulu kwePermian, lapho ama-95% azo zonke izinhlobo zezilwane ezanyamalala ebusweni beplanethi yethu! Futhi imbangela yezinsuku eziyisihlanu zokuqothulwa kwaba ukukhubazeka kwe-biosphere noma okuthiwa "umgogodla wengozi womjikelezo we-carbohydrate".
Eqinisweni, uprofesa wezokwelapha namuhla uyaphazamisa okufanayo - ukuhlolwa kwesithupha kweMhlaba kusendleleni ...
Usosayensi usuvele uthola ifomula ehlobanisa ushintsho oluthile emtwini wekhabhoni elingenalutho olwandle olwenziwe ngesilinganiso salolu shintsho. Kulungile, noma ngamazwi alula - maduze nje ikhabhoni elwandle liyoba kakhulu kangangokuthi ukuphela kokuphela kwesithupha kungenakugwema!
Into edabukisayo ukuthi leli qiniso lihambisana nezifundo ze-Intergovernmental Panel on Climate Change. Ngo-2100, babikezela "ukucebisa" kwamanzini nge-310 gigaton yekhabhoni, futhi ngesimo esibi kunazo zonke - nge-gigaton engu-500, okuyinto kunoma ikuphi isondelene kakhulu nomngcele omangalisayo womjikelezo we-carbohydrate!
"Lokhu akusho ukuthi ngosuku olulandelayo kuyoba nenhlekelele," kusho uDaniel Rothman, kodwa ngesimo sezulu esinjalo sishintsha umjikelezo wekhabhoni awusekho. Ngakho-ke, sesidlulile iphuzu lokungabuyeli ... "
