Yilokho, ingane yethu inesithakazelo emicabangweni eyinkimbinkimbi, engabonakali noma yesayensi, ngisho noma ingakakwazi ukuqonda yonke into. Nawu umbuzo onzima obuzwayo: kuyini ukufudumala komhlaba?
Kungakhathaliseki ukuthi oyedwa uchwepheshe kulo mkhakha, ubunzima bukhona ekuchazeni lesi sigameko esiyinkimbinkimbi futhi esinezici eziningi enganeni, ngamazwi nemibono angakwazi ukuyihlanganisa. Indlela yokuchaza ukufudumala kwembulunga yonke ezinganeni, ngaphandle kokubesabisa noma, ngokuphambene nalokho, ukubenza bangabi nandaba?
Ukuguquka kwesimo sezulu: ukubaluleka kokungakuphiki okusobala
Ukuguquka kwesimo sezulu, ukuguquguquka kwesimo sezulu, ukufudumala kwembulunga yonke ... Noma ngabe igama elisetshenziswayo liyafana, futhi ngazwi linye phakathi komphakathi wesayensi : Isimo sezulu somhlaba sishintshe kakhulu emashumini ambalwa eminyaka adlule, ngesivinini esingakaze sibonwe, ikakhulukazi ngenxa yemisebenzi yabantu.
Ngakho-ke, futhi ngaphandle kokuthi usesimweni sokungabaza kwesimo sezulu futhi uphika izigidi zedatha yesayensi eqinile, kungcono ungawunciphisi lo mkhuba lapho ukhuluma nengane. Ngoba uzokhula kuleli zwe elinezinxushunxushu, inqobo nje uma ezilungiselele lezi zinguquko, futhi eqaphela imiphumela eyoba khona, okungenani ohlotsheni lwesintu.
Ukufudumala kwembulunga yonke: umqondo we-greenhouse effect
Ukuze ingane iqonde ngokugcwele umqondo wokufudumala kwembulunga yonke, kubalulekile ukuchaza, ngokushesha nangokulula, ukuthi kuyini umphumela we-greenhouse. Sihlala sikhuluma ngamagesi abamba ukushisa akhishwa abantu, ngakho wona kanye umbono womphumela we-greenhouse usenhliziyweni yendaba.
Kungcono kakhulu ukuziveza ngamagama alula ahambisana neminyaka yengane, isibonelo ukuthatha isibonelo i-greenhouse engadini. Ingane iyaqonda, futhi mhlawumbe isibonile kakade, ukuthi kushisa endaweni ebamba ukushisa kunangaphandle. Kuyisimiso esifanayo soMhlaba, lapho kuhle ngenxa yomphumela we-greenhouse. Empeleni iplanethi izungezwe ungqimba lwegesi olusiza ukugcina ukushisa kwelanga. Ngaphandle kwalolu ngqimba lwalokho okubizwa ngokuthi “igesi ebamba ukushisa”, bekungaba -18 ° C! Uma ibalulekile, lo mphumela we-greenhouse ungase ube yingozi uma ukhona kakhulu. Ngendlela efanayo utamatisi kamkhulu (noma kamakhelwane) obungabuna uma kushisa kakhulu endlini ebamba ukushisa, ukuphila emhlabeni kusengozini uma amazinga okushisa enyuka kakhulu, futhi ngokushesha kakhulu.
Cishe iminyaka eyi-150, ngenxa yokungcolisa imisebenzi yabantu (ezokuthutha, izimboni, ukuzalanisa okujulile, njll.), sekube namagesi abamba ukushisa (CO2, methane, ozone, njll.) abelokhu enqwabelana endaweni yethu. emkhathini, yisho "kwibhamuza lokuvikela" lePlanethi. Lokhu kunqwabelana kubangela ukwanda kwamazinga okushisa aphakathi nendawo emhlabeni: ukufudumala kwembulunga yonke.
Umehluko obalulekile phakathi kwesimo sezulu nesimo sezulu
Uma kukhulunywa ngokukhuphuka kwamazinga okushisa enganeni, kubalulekile, kuye ngeminyaka yayo, vele, ngayo chaza umehluko phakathi kwesimo sezulu nesimo sezulu. Kungenjalo, uma kufika ubusika, kungenzeka akutshele ukuthi umqambele amanga ngezindaba zakho zeGlobal Warming!
Isimo sezulu sisho isimo sezulu endaweni ethile ngesikhathi esithile. Kuyisibikezelo esifika ngesikhathi nesinembayo. Isimo sezulu sibhekisela kuzo zonke izimo zomoya kanye nesimo sezulu (umswakama, imvula, ukucindezela, izinga lokushisa, njll.) eziqondene nesifunda, noma, lapha, kuyo yonke iplanethi. Kucatshangwa ukuthi kuthatha iminyaka engaba ngamashumi amathathu yokubhekwa kwesimo sezulu nesimo somoya ukuze kutholwe isimo sezulu sendawo.
Ngokusobala, ukuguquguquka kwesimo sezulu akubonakali kumuntu kusukela kolunye usuku kuye kolunye, njengesimo sezulu. Ukushintsha kwesimo sezulu kwenzeka phakathi namashumi noma amakhulu eminyaka, nakuba ukushintsha kwesimo sezulu kancane kancane kuqala ukubonakala esikalini somuntu. Ukuthi bekubanda kakhulu kulobu busika akusho ukuthi isimo sezulu asisavuthi.
Izinga lokushisa emhlabeni lingase lenyuke, ngokwezilinganiso zakamuva zesayensi okunye okungu-1,1 kuye ku-6,4 ° C phakathi nekhulu lesi-XNUMX.
Ukufudumala kwembulunga yonke: chaza ngokushesha imiphumela yekhonkrithi
Uma lesi simo sokufudumala kwembulunga yonke sesichazelwe izingane, kubalulekile ukuthi ungafihli imiphumela kubo, njalo ngaphandle kokulingisa, ngokuhlala kuyiqiniso.
Esokuqala, futhi ngokungangabazeki esisobala kakhulu, siwukuthi ukuphakama kolwandle, ikakhulukazi ngenxa yeqhwa elincibilikayo elikhona eMhlabeni. Ezinye iziqhingi namadolobha asogwini anyamalala, okwaholela engcupheni enkulu ababaleki besimo sezulu. Ukufudumala kwezilwandle nakho kwandisa ingozi izenzakalo zesimo sezulu esibi kakhulu (izishingishane, izivunguvungu, izikhukhula, amagagasi okushisa, isomiso….). Abantu, kodwa ikakhulukazi izitshalo nezilwane, bangase bangakwazi ukuzivumelanisa nezimo ngokushesha ngokwanele. Ngakho-ke izinhlobo eziningi zezilwane zisengozini yokunyamalala. Nokho, uMuntu nokulinganisela okuntekenteke kokuphila kuncike ngokwengxenye ekubeni khona kwalezi zinhlobo. Sicabanga ikakhulukazi izinyosi nezinye izinambuzane ezinempova, okuvumela izitshalo ukuba zithele izithelo.
Nokho, uma ukuphila komuntu kungase kuthinteke kakhulu, akukho okushiwo ukuthi ukuphila eMhlabeni kuzoshabalala ngokuphelele. Ngakho-ke kungenxa yabantu nezinhlobo eziphilayo zamanje lapho isimo sizoba nzima nakakhulu.
Ukufudumala kwembulunga yonke: ukuhlinzeka ngezixazululo ezibambekayo kanye nokubekela izingane isibonelo
Ukuchaza ukufudumala komhlaba enganeni kusho nokwabelana ngezixazululo zokulwa, noma okungenani ukunqanda, lesi simo. Uma kungenjalo ingane izifaka engozini yokuzizwa idangele, icindezelekile futhi ingenakuzisiza ngokuphelele lapho ibhekene nesenzakalo esingaphezu kwayo. Sikhuluma ikakhulukazi “ukukhathazeka ngokwe-eco".
Sesingachaza kakade ukuthi amazwe ahlukahlukene azibophezela (kancane kancane, kunjalo) ekunciphiseni ukukhishwa kwawo kwamagesi abamba ukushisa, nokuthi ukulwa nokuguquguquka kwesimo sezulu manje kubhekwa njengento enkulu.
Khona-ke, singamchazela ukuthi kukuwo wonke umuntu ukushintsha indlela yakhe yokuphila nemikhuba yokudla ukuze alondoloze iPlanethi Yomhlaba njengoba siwazi. Ikona imfundiso yezinyathelo ezincane, noma inyoni yomzwilili, okuchaza ukuthi wonke umuntu unesabelo sakhe somthwalo wemfanelo kanye neqhaza lakhe okufanele alibambe kulo mzabalazo oqhubekayo.
Hlela imfucuza yakho, uhambe ngezinyawo, gibela ibhayisikili noma izithuthi zomphakathi kunemoto, yidla inyama encane, thenga imikhiqizo engapakishiwe kancane futhi kancane kancane usebenzise indlela yokulahla imfucumfucu, thenga izinto ezingamasekeni uma kungenzeka, ncamela ishawa kunokugeza, yehlisa izinga lokushisa. ukushisisa, yonga amandla ngokucisha amadivaysi kokubekwe eceleni ... Ziningi izinto ezincane okumelwe zenziwe ingane enekhono kakhulu ekuziqondeni nasekuzenzeni.
Ngalo mqondo, ukuziphatha kwabazali kubalulekile, ngoba kungenzeka nika ithemba kubantwana, ngubani-ke obona ukuthi kungenzeka ukwenza nsuku zonke ngokumelene nokushintsha kwesimo sezulu, ngokusebenzisa "izinyathelo ezincane" okuyinto, ukuphela kokuphela - futhi uma wonke umuntu ekwenza - kakade benza okuningi.
Qaphela ukuthi kukhona izinsiza eziningi zemfundo, izivivinyo ezincane nezincwadi ku-inthanethi, ezitolo zezincwadi nasezindlini zokushicilela zezingane okuvumela ukusondela esihlokweni, ukusichaza noma ukusijulisa. Akufanele singabaze ukuthembela kulezi zisekelo, ikakhulukazi uma indaba yokufudumala kwembulunga yonke isithinta kakhulu, uma isikhathaza, uma singazizwa sifanelekile ukuyichaza noma uma sesaba. ukuyinciphisa.
