Esinye sezici ezinomthelela ekulawuleni izinga lokushisa ezingeni lomhlaba wonke yi i-albedo yomhlaba. Kuyaziwa njengomphumela we-albedo futhi kuyipharamitha ethonya kakhulu izinga lokushisa futhi, ngakho-ke, kuthinta ukushintsha kwesimo sezulu. Kufanele wazi kahle imiphumela ye-albedo ukuze uthole iziphetho futhi uthuthukise izinhlelo ezisiza ukunciphisa imiphumela ye-albedo. ukufudumala kwezwe.
Kule ndatshana sizochaza ukuthi yini i-albedo yoMhlaba nokuthi ishintsha kanjani futhi iguqula kanjani izinga lokushisa lomhlaba. Lesi simo sithinta kanjani ukuguquka kwesimo sezulu?
Yini i-albedo yoMhlaba?
Sishilo ukuthi lo mphumela unomthelela emazingeni okushisa omhlaba ngendlela ethile. I-Albedo ingumphumela owenzeka lapho imisebe yelanga ishaya ngaphezulu futhi le misebe ibuyiselwa emuva emkhathini. Njengoba sazi, hhayi bonke imisebe yelanga lokho kuthinta ukuhlala kweplanethi yethu noma kumuncwa umhlaba. Ingxenye yale radiation yelanga ibonakala ibuyele emkhathini ngokuba khona kwamafu, enye igcinwe emkhathini ngo amagesi abamba ukushisa bese kuthi abanye bavele phezulu.
Yebo, kuya ngombala wobuso lapho imisebe yelanga iwela khona, kuzokhonjiswa inani elikhulu noma kuzofakwa inani elikhulu. Ngemibala emnyama, izinga lokumunca imisebe yelanga liphakeme. Okumnyama umbala okwazi ukumunca inani elikhulu lokushisa. Ngokuphambene nalokho, imibala ekhanyayo iyakwazi ukukhombisa inani elikhulu lemisebe yelanga. Kulokhu, okubhekiswe kuye kunesilinganiso sokumuncwa esiphakeme kakhulu. Lesi yisizathu esenza ukuthi ngaphambili emakhaya kubonakale izindlu zabamhlophe kuphela. Kuyindlela yokuvikela indlu kusuka emazingeni okushisa aphezulu ehlobo ngenxa yokumuncwa kokushisa okuncane.
Okwesethi yabo bonke ubuso beplanethi kanye namazinga wabo wokumunca nokubonisa imisebe yelanga akha i-albedo yoMhlaba. Ngokuya ngombala ogqamile noma izinhlobo ezahlukahlukene zomhlaba eziseplanethi yethu, sizobe sithatha imisebe yelanga eyehlayo noma engaphansi. Leli qiniso linomthelela omkhulu ekuguqukeni kwesimo sezulu njengoba sizobona kulesi sihloko.
I-Albedo nokuguquka kwesimo sezulu
Impela uyazibuza ukuthi lo mphumela uhlobene kanjani nokushintsha kwesimo sezulu kanye nokushisa komhlaba. Yebo, i-albedo yoMhlaba inethonya elikhulu, ngaphezu kwawo wonke amagesi abamba ukushisa kanye nokwanda kokugxila kwawo emoyeni. Izingongolo Zomhlaba zinomphumela ophawuleka kakhulu we-albedo, ngoba indawo imhlophe ngokuphelele ngenxa yobukhona bamakepisi we-polar. Lokhu kusho ukuthi imisebe yelanga eningi ewela phezu kwezigxobo ibonakala emuva futhi ayigcinwa njengokushisa.
Ngakolunye uhlangothi, indawo enethoni emnyama njengezilwandle, izilwandle ngisho namahlathi sithola isilinganiso sokumuncwa esiphakeme. Lokhu kungenxa yokuthi izilwandle zimnyama ngombala njengezihlahla. Njengoba kuboniswa inani elincane lemisebe yelanga, izinga lokumuncwa kwalo liphakeme.
Ubudlelwano phakathi kwe-albedo yoMhlaba kanye nokuguquka kwesimo sezulu ukuthi ngokuncibilika okuseduze kwamakhekheba eqhwa asezindaweni ezibandayo, inani lemisebe yelanga ebuyiselwa emkhathini liyancipha. Ingxenye encibilikayo ishintsha umbala wayo usuke kokukhanya uye kokumnyama, ngakho-ke ukushisa okuningi kuzomunceka futhi izinga lokushisa lomhlaba lizokhuphuka kakhulu. Lokhu kufana nomhlophe oluma umsila.
Sikhuphula amazinga okushisa omhlaba ngenxa yokwanda kwamagesi abamba ukushisa agcina ukushisa emkhathini, ngakho-ke, amakhemikhali asezindaweni ezibandayo ayancibilika, nawo abamba iqhaza empumelelweni yokupholisa ngenxa yemisebe yelanga okugxile ebusweni bayo.
Amahlathi athathwa njengamademoni
Njengabantu ngaso sonke isikhathi bavame ukweqisa, ngokushesha nje lapho bezwa ukuthi amahlathi anezinga eliphakeme lokumunca imisebe yelanga baphonsa izandla zabo emakhanda abo. Akugcini ngokwenzeka ngalokhu kuphela, kodwa ngayo yonke into abangayazi. Akuyona yonke into eyeqisayo futhi yonke into ingenye. Ake sibone, kuyiqiniso ukuthi ihlathi liyakwazi ukumunca imisebe yelanga ethe xaxa, ngakho-ke izinga lokushisa lizokhula. Ngaphezu kwalokho, njengoba izingqimba zeqhwa elisempumalanga zincibilika, kuzothathelwa indawo indawo yolwandle, njengoba lokhu kumnyama futhi, ngakho-ke, kukhulisa ukumuncwa kwawo.
Yebo, noma ngabe kunjalo, kufanele sikhumbule ukuthi amahlathi aqukethe izigidi zezinhlobo zezitshalo ezenziwayo photosynthesis futhi lokho kuzohlanza umoya wethu, kunciphisa ukuminyana kwamagesi abamba ukushisa esiye sawakhiphela emkhathini. Akunakwenzeka ngabantu ukuthi bagcine sebenza amademoni lawa mahlathi ngokumane nje bakhulume kabi imininingwane abangakwazanga ukuyelapha noma abangaqondi kahle ngayo.
Ngaphezu kwalokho, kunezifundo eziningi eziqinisekisa lokho ithonya lezixuku ezinkulu zamahlathi lapho kukhona imvula. Uma inqwaba yamahlathi iba ningi, imvula iba nkulu, okuyisisekelo sesomiso somhlaba jikelele esibangelwe ukuguquka kwesimo sezulu. Yize kuwubuwula ukusho, zonke izinyathelo zokuqapha zincane, kepha izihlahla zisinikeza ne-oxygen esiyiphefumulayo futhi ebesingeke siphile ngaphandle kwayo.
Isixazululo senkinga
Akudingeki ukuthi wenze idemoni lezihlahla noma uthathe izinto ngokweqile. Okubalulekile ukunciphisa ukuminyana kwamagesi abamba ukushisa emkhathini kusetshenziswa amandla avuselelekayo kanye nokuguqula imikhuba yokusetshenziswa ukuguqula uhlelo lwezomnotho. Lokhu kuzoholela ekutheni kube namagesi amancane agcina ukushisa emkhathini, futhi ngalokho izingongolo zoMhlaba ngeke zincibilike. Uma izingongolo zingancibilikisi, indawo engaphezulu ebamba ukushisa ngeke inyuke, namazinga olwandle ngeke enyuke.
Uma sitshala futhi sandisa ubukhulu bamahlathi, sizophinde futhi sinciphise ukugcwala kwamagesi abamba ukushisa emkhathini.
Sethemba ukuthi ukushintsha kwesimo sezulu akuqhubeki nokuthuthuka futhi abantu abaqhubeki nokufaka amahloni amahlathi ngalesi sizathu.
Enye indatshana enhle KAKHULU efundisayo, ifundisa kakhulu ngale miqondo EFANELEKAYO… Siyakuhalalisela IGERMAN P.
Isihloko esihle kakhulu. Kukhona okumele ukufunde. Kubalulekile ukufundisa abantu abenza imisebenzi eminingi yokuphanga: ukushisa impahla yezitshalo, i-PET, i-Styrofoam, nabanye. Ngaphezu kokufaka ama-herbicides amakhemikhali. Impilo nempilo yomhlaba wonke.
