Mishumo pamberi pemusangano wemamiriro ekunze epasirese - kupenya kwetariro, asi kuchine zvakawanda zvekuita

Pamberi pemusangano wemamiriro ekunze muSharm El Sheikh, mishumo yakakosha kubva kumasangano eUN yakaburitswa mumazuva mashoma apfuura, semakore apfuura. Zvinotarisirwa kuti izvi zvichange zvichitariswa munhaurirano. 

UNEP EMISSIONS GAP REPORT 2022

The Emissions Gap Report yeUN Environment Programme (UNEP) inoongorora mashandiro ezviyero zvazvino uye mipiro iripo yenyika (Nationally Determined Contributions, NDC) uye inozvipa kukudzikisira kwegreenhouse gas (GHG) kunodiwa kuti uwane 1,5°. C kana 2°C tarisiro inodiwa, yakatarisana. Chirevo ichi chinoongororawo matanho muzvikamu zvakasiyana akakodzera kuvhara iyi "gap". 

Iwo akanyanya kukosha data ndeaya anotevera: 

• Nezviyero zvazvino chete, pasina kutarisisa NDC, ndiko kuburitswa kweGHG kwe2030 GtCO58e kunotarisirwa muna 2 uye kudziya kwe2,8°C pakupera kwezana ramakore. 
• Kana maNDC ese asina zvisungo akashandiswa, kudziya kwe2,6°C kunogona kutarisirwa. Nekushandisa maNDC ese, ayo akabatana nemamiriro ezvinhu akadai serubatsiro rwemari, kuwedzera kwekushisa kunogona kudzikiswa kusvika pa2,4 ° C. 
• Kuti tidziye kudziya kusvika pa1,5°C kana 2°C, zvinobuda muna 2030 zvinogona kungosvika 33 GtCO2e kana 41 GtCO2e. Zvakadaro, kuburitswa kunobva kuNDC iripo 23 GtCO2e kana 15 GtCO2e kumusoro. Iri gaka rekuburitsa hutsi rinofanirwa kuvharwa nemamwe matanho. Kana maNDC ane zvimiso akashandiswa, gap rekuburitsa rinodzikira ne3 GtCO2e imwe neimwe.
• Hunhu hwakadzikira zvishoma pane mumishumo yapfuura sezvo nyika zhinji dzakatanga kuita matanho. Kuwedzera kwepagore kwehutsi hwepasirese kwakadzikirawo zvishoma uye ikozvino 1,1% pagore.  
• MuGlasgow nyika dzese dzakakumbirwa kuti dziratidze maNDC akavandudzwa. Zvakadaro, izvi zvinongotungamira kune imwezve yakafanotaurwa kudzikiswa kweGHG mu2030 ye0,5 GtCO2e kana isingasviki 1%, i. 
• Nyika dzeG20 dzingangotadza kusvika pazvinangwa zvavanenge vazvimisira, izvo zvichawedzera gaka rekuburitsa uye kukwira kwekushisa. 
• Nyika zhinji dzakaendesa zvinangwa zve net-zero. Nekudaro, pasina zvibodzwa zvenguva pfupi yekuderedza, kushanda kwezvinangwa zvakadaro hakugone kuongororwa uye hakuna kuvimbika zvakanyanya.

Nhoroondo yeUNFCCC SYNTHESIS 

Secretariat yemamiriro ekunze yakatumwa nenyika dzine makondirakiti kuti iongorore mhedzisiro yeNDC yakatumirwa uye zvirongwa zvenguva refu. Chirevo ichi chinouya kumhedzisiro dzakafanana seUNEP Emissions Gap Report. 

• Kana maNDC ese aripo akashandiswa, kudziya kunenge kuri 2,5°C panopera zana rino. 
• Nyika makumi maviri neina chete dzakaendesa NDCs dzakagadziridzwa mushure meGlasgow, isina mhedzisiro.
• Nyika makumi matanhatu nembiri, dzinomiririra 62% yehutsi hwepasi rose, dzine zvinangwa zvenguva refu net-zero, asi kazhinji pasina hurongwa hwekuita. Kune rimwe divi, ichi chiratidzo chakanaka, asi chine njodzi yekuti matanho anodiwa nekukurumidza anomiswa kusvika kure kure.   
• Pakazosvika 2030, kuburitswa kweGHG kunotarisirwa kuwedzera ne10,6% zvichienzaniswa ne2010. Hapana kumwe kuwedzera kunotarisirwa mushure me2030. Uku ndiko kuvandudzwa kwekuverenga kwakapfuura uko kwaida kuti 13,7% iwedzere kusvika muna 2030 zvichienda mberi. 
• Izvi zvichiri kusiyana zvakanyanya nekudzikiswa kweGHG kunodiwa kuti izadzise chinangwa che1,5 ° C che45% ne2030 zvichienzaniswa ne2010, uye 43% zvichienzaniswa ne2019.

Iyo ichangoburwa Greenhouse Gas Bulletin inoti: 

• Kubva 2020 kusvika 2021, kuwedzera kwe CO2 kusungwa kwaive kwakakura kupfuura avhareji yemakore gumi apfuura uye kusungirirwa kuri kuramba kuchikwira. 
• Atmospheric CO2 concentration yaive 2021 ppm muna 415,7, 149% pamusoro pe pre-industrial level.
• Muna 2021, kuwedzera kwakasimba kwemethane concentration mumakore makumi mana kwakaonekwa.

Mushumo wepagore wemamiriro ekunze epasi rose uchaunzwa muSharm El Sheikh. Imwe data yakatounzwa kare:

• Makore 2015-2021 aive makore manomwe anodziya zvakanyanya munhoroondo 
• Tembiricha yepasi rose inodarika 1,1 ° C pamusoro peiyo pre-industrial level ye1850-1900.
