Masayendisiti akaisa muganho wekuwedzera kwetembiricha yepasi rose mu2 ° C. Nei tembiricha iyoyo? Ongororo dzakasiyana dzinoratidza kuti kubva pakudziya kwetembiricha dzepasi rese, shanduko muzvakatipoteredza uye kutenderera kwemhepo yepasirese, shanduko dzakagadzirwa dzinogona kunge dzisingachinjiki uye dzisingatarisike nekufamba kwenguva.
Nechikonzero ichi, kugara pasi pe 1,5 ºC yekudziya kwepasirese ndechimwe chezvinangwa zvinokurudzirwa nechibvumirano cheParis uye kuti nyika makumi mashanu neshanu dzakabvuma kutora semuganhu wekuguma kwezana rino. Zvisinei, 65% yehuremu hwemakomo marefu eAsia echando anogona kurasikirwa kana greenhouse gasi inoburitsa ichienderera seizvi. Aya mazaya eAsia ari kunyungudika?
Asia Glacier Kudzidza
Chidzidzo, chakatungamirwa neUniversity yeUtrecht (Holland), chinoratidza kuti kusvika pa65% yehukuru hwemakomo echando akakwira muAsia anogona kurasikirwa pasi pechiitiko chekuenderera kwakakwira mwero wegreenhouse gasi kugadzirwa.
Kana emesi ichienderera padanho rekuwedzera uye rakawedzera ravari kuita nhasi, iyo kondinendi yeAsia yaizotarisana nekurasikirwa kukuru kwechando izvo zvinokanganisa zvakasikwa ecosystem uye kuunza zvakakomba kugovera mhedzisiro kune iyo nzvimbo dzinorarama nezvayo. Kunwa mvura, nzvimbo yekurima uye madhayamagetsi emvura angangotyisidzirwa nekuderera kwehukuru hweaya maaizi.
Mumatunhu ane mvura inonyungudika kubva kumazaya echando akakosha pakuyerera kwenzizi uye nehupenyu hwezvisikwa nemhuka zvine hukama nazvo. Kushandiswa kwenzizi dzekudiridza kwezvirimwa neminda yemupunga iyo inopihwa mvura kubva mumazaya echando kunogona kudzikiswa nekutsakatika kwayo.
Iine tembiricha yakakwira kudziya nekuda kwegreenhouse gasi inoburitsa inoitika muChina, sezvo 60% yemusanganiswa wesimba inoenderana nekupiswa kwemarashaKunaya kwakaita muchando kunowedzera huwandu hwadzo uye mazaya echando anorasikirwa nehukuru nevhoriyamu.
Kuderedzwa kwerwizi kuyerera kunogona kutungamira kumatambudziko ane chekuita nechikafu uye kugadzirwa kwesimba, izvo zvinogona kuve nemhando dzese dzemhedzisiro yakaipa.
Impact uye mhedzisiro kuongororwa
Kuti uongorore zvakakanganiswa nekurasikirwa neaya echando pamvura, zvekurima, nemadhamu emagetsi, nyanzvi dzakashanda pachidzidzo ichi chakaburitswa mumagazini reNature dzakashandisa nzvimbo zhinji dzemvura uye nedziomhu tembiricha kubva kune yanhasi mamiriro ekunze. Saizvozvowo, iwo aive akavakirwa pane satellite data, mamiriro emamiriro ekunze ekufungidzira ekuchinja mune kunaya uye tembiricha inosvika mazana maviri nemazana maviri, uye zvakare vakashandisa mhedzisiro yebasa ravo remumunda rakaitwa muNepal nemaUAVs.
Mhedziso dzakapihwa neichi chidzidzo zvinoenderana nezvakafanotaurwa mamiriro ekunze, kunyangwe yemamiriro akakodzera umo Chibvumirano cheParis chinozadzikiswa uye pakati nepakati tembiricha yepasi isingakwiri pamusoro pe 1,5 ° C, zvicharasika 35% yehukuru hwema glaciers pagore 2100.
Nenhepfenyuro inofungidzirwa inowedzera yakatenderedza 3,5 ° C, 4 ° C, uye 6 ° C, paizove nekurasikirwa kukuru kweinenge 49%, 51%, uye 65% zvichiteerana.
Mhedzisiro yekurasikirwa nechando
Izvo zvakanyanya kuoma kuona mhedzisiro iyo kurasikirwa kwechando kuchave nako pane mamiriro ekunze epasi. Chii chiri chokwadi ndechekuti mhedzisiro iyo ichave ichave isina kunaka. Kuti uenderere mberi nekuziva mhedzisiro yekudzoka kwemazaya echando, chidzidzo chakakura chinodikanwa chinotsanangudza maitiro epanyama neesocial uchishandisa dhata kubva kunzvimbo zhinji, kusanganisira mhedzisiro yechidzidzo ichi.
Iyo yepedyo iwe padyo nechando nzvimbo, zvakanyanya kukosha Ndiyo mvura yekusanganiswa kwezviitiko zvakasiyana zvevanhu. Kunyangwe mune dzimwe nzvimbo mupiro wemvura inoyangarara kumvura kune nzizi iri yakakura kudarika mune dzimwe, iyo nzvimbo yekumadokero yakaoma yedunhu, senge Indus Basin, inoenderana zvakanyanya nekuyerera kuri kuita kwemvura inonyungudika kubva pamazaya echando.
