Sine iminyaka emithathu kuphela ukuvimbela enhlekeleleni sezulu

Uma kukhishwa kwekhabhoni global uqale ukunqabela, esikhathini esiyiminyaka emithathu ezayo, iplanethi ulinde emazingeni ayingozi yokushintsha kwesimo sezulu, futhi imigomo ebekwe Paris sivumelwano sezulu kuyoba lungafinyeleleki. Encwadini eyashicilelwa ephephabhukwini "Imvelo", izazi, kuhlanganise owayeyinhloko UN Climate uChristiana Figueres, nonguNobhala evezwe yini imigomo kudingeka izuzwe 2020 ukuze iplanethi, ukuze sikwazi nginethemba ukuba sibhekane ngokuphumelelayo kwesimo sezulu.

sezulu nenhlekelele

Ochwepheshe bhala ukuthi ngisho ne ukwanda izinga lokushisa embulungeni yonke ngo-1 ° C (1.8 ° F) ulwandle ice uyaqhubeka ncibilika kwamakhorali njengalokhu kufa lokho, ifofobaliswa semvelo. Nakuba thina ayisekho ukwandisa inani isikhutha esiphumela emoyeni, zisaphakeme emkhathini, ngakho izinga lokushisa siyaqhubeka sikhula. Iminyaka emithathu eyalandela kungenziwa ngokuthi senguquko kulesi simo.

Kodwa akufanele zigcwale. Ngokungangabazeki, izindaba sibe iminyaka emithathu kuphela ukusungula ukulawula isimo, kungase kubonakale silahle ithemba ngo isimo sezombangazwe samanje, kodwa kukhona izimpawu kuhle kabi ukuba sibe nethuba kugucula konkhe. Abasunguli bale ncwadi sithi ngisho manje zikhona izinqubo ezingaba oluzobhekelela ukuze kukhawulwe lokhu ukufudumala. Noma kunjalo, kudingeka sithathe isinyathelo ngokushesha ngangokunokwenzeka.

"Lezi zinhloso kungaba, kakhulu, emibonweni yami, futhi neze - ngiyaphupha - ababhali ukubhala. - Noma kunjalo, siphila esikhathini lapho ukuguqulwa lomchazi futhi bakholelwa ukuthi ngokugxila mayelana nalezi zindaba, singakwazi ukusungula izinto. " Le ncwadi ulandisa indlela wonke kumele ngo-2020, ukuze sikwazi ukugwema elimazayo futhi iyingozi kwesimo sezulu.

Amandla ezivuselelekayo

Zithi ophinde uvuseleleke kufanele ebangela amaphesenti okungenani 30 supply emhlabeni, okuyinto engcono kakhulu 6.5 amaphesenti kuka-2015. Ukwakhiwa kanye nengqalasizinda kumele ngokuphelele decarbonised ngu 2050, futhi umkhakha esindayo kuyodingeka ukwandisa ukusebenza kahle yabo futhi kuncishiswe kwekhabhoni.

ezokuthutha

Inkinga enkulu izithuthi. izimoto Electric kuyomelwe babe amaphesenti okungenani 15 we yokuthengisa izimoto ezintsha emhlabeni wonke, okungaphezulu kakhulu kwalokho okungakulahlekela wamanje 1 amaphesenti. Kufanele kufakwe izinhlelo nekunciphisa komoya ngenxa kwezithuthi zomphakathi kanye nezindawo 20 per cent nokuncipha kogesi wendlwana evikela izithombo kusukela izindiza.

WOKUTSHALA IZIHLAHLA

Ungakhohlwa mayelana nezinkinga yokusetshenziswa komhlaba. Uma ngesikhathi izinguquko eyishumi ekusetshenzisweni kwemihlaba nokususa isiteshi kuthiwa wayeka ngokuphelele futhi baqala sokubuyiselwa kwamahlathi 2030, kuyokusiza hhayi kuphela ukwehlisa zonke kwekhabhoni kuqanda, kodwa futhi ukuvikela ukuphepha amanzi kanye nezitshalo ezihlukene ezikuzo.

uxhaso

Uma kuziwa ekusekeleni ngezimali, bohulumende kumele bandisa umsebenzi, njengoba abalobi ukubikezela ukuthi iningi imali ehlelelwa isinyathelo sezulu kuyofika ezingxenyeni ezizimele. Kungase kubonakale ukuthi uhla lwemisebenzi saziso sikhulu kakhulu, kodwa uma singakhathali ukunciphisa kwekhabhoni ke sizithola phakathi kwalabo uzohlupheka kwasekuqaleni.

Kanjani ukuze sigweme izinhlekelele

Le ncwadi ithi indlela ukuthi afeze lezi zinhloso. Ochwepheshe bathi isidingo izinqubomgomo nezenzo ngesisekelo idatha yesayensi okuthembekile. Lokhu kusho ukuthi ososayensi kudingeka zazi ukuthi zingakhetha ukuchaza kangcono imibono yabo kanye nemigomo - balalelisise kubo. Khona-ke izinga izixazululo ekhona, futhi ukukwenza ngokushesha ngangokunokwenzeka kufanele udinga ukwandisa. Wonke amazwe kufanele sitfutfukise tinhlelo ukukhiqiza amaphesenti 100 kagesi walo kusuka renewable sources.

Ekugcineni, kudingeka ukuba nombono oqhakazile. Yonke imizamo yenziwe futhi uyifake nasezinhlelweni zethu zingase zibonakale lutho, futhi kucindezela, kodwa kufanele sikhumbule ngezinto izixazululo ekhona futhi zempumelelo ukuthi bayakufanelekela ukwabelana nomunye.

"Kufanele sikhumbule ukuthi akukho okwahlula, futhi le nto ifanelekile isimo sethu senkinga - ababhali ukuphetha. - Kuyohlale kunokuningi nalabo abafihla amakhanda abo esihlabathini futhi uzibe izingozi wokuguquka kwesimo sezulu. Kodwa iningi lethu bazimisele ukuze banqobe lo inertia. Ake uhlale babenethemba lokuhle futhi ngeke basebenze ndawonye. "
