Iingxaki Global yokusingqongileyo kunye nezisombululo zazo

Yi Kwisiqingatha sesibini zenkulungwane yamashumi amabini, nefuthe loqoqosho isintu indalo esingqongileyo lifikelele enkulu etshabalalisayo kangangokuba kube balahlekelwa amandla okuphilisa ngokwayo.

iingxaki zehlabathi of engqongileyo kunye nophuhliso oluzinzileyo - ngxaki zokuyeka yempembelelo eyingozi woluntu kwindalo esingqongileyo.

Phakathi kwinkulungwane yokugqibela, imvelo yaba ibingengomcimbi zangaphakathi kwilizwe elithile, njengoko Iziphumo zongcoliseko ngenxa umsebenzi kwimizi kuboniswa kuphela kwiindawo nokuqwalaselwa eliphezulu kakhulu labantu mveliso enobungozi. Kule yee-, iingxaki zokusingqongileyo ufumene kwinqanaba lengingqi, ekubeni ukukhutshwa intsimbi ukufikelela kumazwe angabamelwane, eza kunye imvula, umoya.

Ekupheleni koo-, le nkundla waya iingxaki zehlabathi kokusingqongileyo yoluntu. Bona azibonakalisa ezifana imikhuba emibi njengoko kokutshatyalaliswa behlabathi ecosystem, izibonelelo, ukulahleka amandla okuphilisa ngokwayo, ukwandiswa imimandla entlekele eziphilayo. Kodwa ekusongeleni ezimbi kakhulu ixesha lethu iba ukutshintsha kwemozulu. Ukwandisa komndilili weqondo lobushushu yonyaka ngokukwanjalo qho kunye nobushushu kwiziganeko ezikhulu zemozulu: izikhukula, imbalela, neenkanyamba, kuneqabaka ngesiquphe kunye nomkhe-. Ukongeza, ukufudumala kungakhokelela ukunyuka kwamazinga olwandle, nezikhukula iindawo ezinkulu, iyenze ibe yokunqaba amanzi acocekileyo. Konke oku kubangela uhlobo lobuntu kunye umonakalo omkhulu.

Ukutshintsha kwemozulu ezinxulumene ukwanda uyondelelwano lwee- greenhouse gases esibhakabhakeni, ngamanye anda "greenhouse effect". greenhouse azive kwi-atmosfera ukutshiswa amafutha, kwamahlathi, njalo-njalo. Noko ke, kukho enye imboniselo ukuba unobangela iphela na iingxaki zokusingqongileyo lwehlabathi, kwaye izingqisho ubudala ubudala solar umsebenzi kunye nemozulu imijikelo.

Iziphumo zongcoliseko

Iziphumo eziphambili wongcoliseko kuxhomekeke kwinto yokuba umonakalo ezingenakulungiswa ukuba izilwanyana kunye nempilo yabantu, iindawo ezingcolisekileyo kakhulu ezivakala ukuze abantu bahlale kunye nemisebenzi eqhelekileyo. Eyona engundoqo iingxaki zokusingqongileyo ixesha lethu, xa engekho, ekugqibeleni kungakhokelela ekubeni umhlaba onokuphila balahlekelwe ngokupheleleyo ubuchule asihlambulule ngokwayo yaye ukuyisonga.

nkqubo karhulumente

Ukuqhubela phambili iingxaki zokusingqongileyo ehlabathini kuye kwakhokelela ekubeni kubekho utshintsho kumgaqo-nkqubo karhulumente kumazwe amaninzi ngokuphathelene nokhuselo lokusingqongileyo. Abasemagunyeni baqala ukumisela imigaqo zokusingqongileyo, ukuchitha ngaphezulu malunga nemilinganiselo zokusingqongileyo.

Kwi yee- uluntu lwamazwe ngamazwe iye yayiqwalasela into yokuba iingxaki zokusingqongileyo ehlabathini ayikwazi ukuba kusonjululwe ngaphakathi ithi ngamnye. kuye kwathi ingqiqo uphuhliso oluzinzileyo, ekuthi ngawo amazwe kufuneka ukuqinisekisa uphuhliso kunye neemfuno kuphela izizukulwana zangoku kodwa elizayo. Ngenxa yoko, kukho ntswela-njani ukuqinisekisa uphuhliso lolondolozo kwaye ngaxeshanye ukunciphisa ifuthe kokusingqongileyo. Ngowe-1997, i-Kyoto Protocol yamkelwa, esicacisa imiqulu ezona ukukhutshwa greenhouse gases yingozi. Eyona njongo iphambili ye-Intanethi - zokunciphisa ungcoliseko ye 5.2% xa kuthelekiswa 1990.

Namhlanje, amazwe amaninzi aphuhlileyo baye bakwazi ukunciphisa kakhulu izinga longcoliseko, okanye ubuncinane ukuzinzisa oko. Kufuneka kuqatshelwe ukuba ukucuthwa ezikhutshwayo kuya malini ukuba imali eninzi kakhulu, kwaye iinzuzo ziya kuba kubonakala kuphela kwixesha elide. Nangona kunjalo, imiba yokusingqongileyo jikelele kufuneka iqwalaselwe, kodwa iindleko kuya kufuneka ukuba ahlupheke ngoku, ukuze kamva ukuba kakhulu emva kwexesha.
