UAlbedo woMhlaba

Enye yezinto ezinefuthe kulawulo lobushushu kwinqanaba lehlabathi yile i-albedo yomhlaba. Iyaziwa njengempembelelo yealbedo kwaye yiparameter echaphazela kakhulu iqondo lobushushu kwaye, ke ngoko, ichaphazela kutshintsha kwe mozulu. Kuya kufuneka uyazi imiphumo ye-albedo kakuhle ukuze ufikelele kwizigqibo kwaye uphuhlise izicwangciso ezikunceda ukunciphisa iziphumo ze-albedo. ukufudumala kwehlabathi.

Kule nqaku siza kuchaza ukuba yintoni i-albedo yoMhlaba kunye nendlela otshintsha ngayo kwaye utshintshe ubushushu behlabathi. Ngaba le nto iyichaphazela njani inguqu yemozulu?

Yintoni i-albedo yoMhlaba?

Sitshilo ukuba esi siphumo sichaphazela amaqondo obushushu ehlabathi ngendlela ethile. IAlbedo sisiphumo esenzeka xa imitha yelanga ibetha umphezulu kwaye le mitha ibuyiselwa endaweni engaphandle. Njengoko sisazi, akunjalo kwakona imitha yelanga echaphazela ukuhlala kwethu kwiplanethi okanye ifunxwe ngumhlaba. Inxalenye yale radiation yelanga ibonakaliswe yabuya yaya emajukujukwini ngobukho bamafu, enye igcinwe emoyeni Igesi yendlu eluhlaza kwaye ezinye zize ngaphezulu.

Ewe, kuxhomekeke kumbala wobuso apho imitha yelanga iwela khona, isixa esikhulu siya kubonakala okanye isixa esikhulu siza kufakwa. Imibala emnyama, izinga lokufunxeka kwelanga liphezulu. Umnyama ngumbala okwaziyo ukufunxa obona bushushu bukhulu. Ngokuchasene noko, imibala ekhanyayo iyakwazi ukubonakalisa isixa esikhulu semitha yelanga. Kule meko, ithagethi yeyona inezinga eliphezulu lokufunxa. Esi sizathu sokuba ngaphambili ezilalini kwabonwa izindlu zabamhlophe kuphela. Yindlela yokugquma indlu ukusuka kumaqondo obushushu aphezulu ehlotyeni ngenxa yokufakwa kancinci kobushushu.

Ewe, iseti yazo zonke iindawo zomhlaba kunye namaxabiso azo okufunxa kunye nokubonakaliswa kwemitha yelanga zenza i-albedo yoMhlaba. Kuxhomekeke kumbala ogqamileyo okanye iintlobo ezahlukeneyo zomhlaba ezikhoyo kwiplanethi yethu, siya kube sithatha ngaphezulu okanye kancinci isiganeko kwimitha yelanga. Le nyani inefuthe elikhulu kutshintsho lwemozulu njengoko siza kubona kweli nqaku.

IAlbedo kunye notshintsho lwemozulu

Ngokuqinisekileyo uyazibuza ukuba ingaba le nto inxulumene nantoni notshintsho lwemozulu kunye nokufudumala kwehlabathi. Ewe, i-albedo yoMhlaba inefuthe elikhulu, ukongeza kuzo zonke iigesi zegreenhouse kunye nokwanda koxinzelelo lwazo emoyeni. Izibonda zomhlaba zinefuthe elibonakalayo le-albedo, kuba umphezulu umhlophe kwaphela ngenxa yobukho beepopic polar. Oku kuthetha ukuba inxenye enkulu, ukuba ayisiyiyo ininzi, yemitha yelanga ewela phezu kweepali ibonakalisiwe umva kwaye ayigcinwanga njengobushushu.

Kwelinye icala, imiphezulu enethowuni emnyama efana neelwandle, iilwandle kunye namahlathi anezinga eliphezulu lokufunxa. Kungenxa yokuba iilwandle zimnyama ngombala njengemithi. Ekubeni imitha yelanga encinci ibonakala, izinga lokufunxa liphezulu. Ukongeza, utshintsho kwi-albedo lunokuba nemiphumo imvula nakwiinkqubo ezahlukeneyo zemozulu.

Ubudlelwane phakathi kwe-albedo yoMhlaba kunye notshintsho lwemozulu kukuba xa kunyibilika umkhenkce osondeleyo, isixa semitha yelanga ebuyiselwe kwisithuba sangaphandle siyancipha. Icandelo elinyibilikayo liguqula umbala walo ukusuka ekukhanyeni uye kubumnyama, ngoko ke ubushushu obuninzi buya kuthathwa kwaye ubushushu bomhlaba buya kunyuka nangakumbi. Oku kufana nomhlophe oluma umsila.

Sandisa ubushushu behlabathi ngenxa yokonyuka kweegesi zegreenhouse ezigcina ubushushu emoyeni kwaye, ngenxa yoko, ii-polar caps ziyanyibilika, zona zona, zibe negalelo kwisiphumo sokupholisa ngenxa yemitha yelanga eyanyanzeliswa kumphezulu wayo.

Amahlathi athathwa njengeedemon

Njengabantu bahlala befuna ukuya kugqithiso, nje ukuba bakuva ukuba amahlathi anamazinga aphezulu okufunxeka kwemitha yelanga baphosa izandla zabo entloko. Ayenzeki kuphela ngale nto, kodwa ngayo yonke into abangayaziyo. Yonke into ayigqithiseli okanye yonke into yenye. Masibone, kuyinyani ukuba ihlathi liyakwazi ukufunxa ubuninzi bemitha yelanga, ke ubushushu buya kunyuka. Ukongeza, njengokuba umkhenkce osembindini womhlaba unyibilika, uya kutshintshwa ube ngumphezulu wolwandle, ukuba mnyama ngakumbi, ke ngoko, yonyusa ukufunxeka kwayo.

Ewe, nokuba kunjalo, kufuneka sikhumbule ukuba amahlathi anezigidi zezityalo ezizisebenzisayo ifotosinthesisi kwaye iya kuwucoca umoya wethu, ukunciphisa ukuxinana kweegesi zegreenhouse esizikhuphele emoyeni. Akunakwenzeka ukuba abantu baphele bengcoliswa ziidemon kula mahlathi ngokusuka nje bagqwethe inkcazelo abangakwaziyo ukuyilungisa okanye abangayiqondi kakuhle. Ukuqonda ngcono indlela i-albedo echaphazela ngayo indawo yethu, ezinye izinto ezifana iitundra.

Ukongeza, kukho izifundo ezininzi ezingqinelanayo impembelelo yamahlathi amakhulu xa kukho imvula. Ubuninzi behlathi, kokukhona isixa semvula, esisisiseko kwimbalela yehlabathi ebangelwe kukutshintsha kwemozulu. Nangona kububudenge ukuyithetha, zonke izilumkiso zincinci, kodwa imithi ikwasinika ioksijini esiyiphefumlayo kwaye ngaphandle kwayo ngekhe siphile.

Isisombululo sengxaki

Akunyanzelekanga ukuba wenze iidemon kwimithi okanye uthathe izinto ngokugqithileyo. Into ebalulekileyo ukunciphisa uxinzelelo lweegesi zegreenhouse emoyeni usebenzisa amandla ahlaziyekayo nokulungisa iindlela zokusetyenziswa ukutshintsha inkqubo yezoqoqosho. Oku kuyakukhokelela ekunciphiseni ubushushu obugcina umoya kwiatmosfera, yiyo loo nto izibonda zomhlaba zinganyibiliki. Ukuba iipali azinyibiliki, umphezulu othatha ubushushu awuyi kunyuka, kwaye namanqanaba olwandle awanyuki.

Ukuba sityala kwaye sandise ubungakanani bamahlathi, siya kunciphisa ngakumbi ukuxinwa kweegesi ze-greenhouse emoyeni, okuya kunceda ukuzinzisa i-albedo yoMhlaba.

Ndiyathemba ukuba utshintsho lwemozulu aluqhubekeli phambili kwaye abantu abaqhubeki nokudemonisa amahlathi ngesi sizathu.
