Chirevo cheOcean Foundation pane 6th IPCC Report

The 6^th Nhoroondo ye IPCC rakaburitswa nerumwe rudzi musi wa 6 Nyamavhuvhu - zvichisimbisa zvatinoziva (kuti mimwe mhedzisiro yekubuda kwegasi regreenhouse yakawandisa hainzvengeki panguva ino), uye zvakadaro ichipa tariro kana tichida kuita munharaunda, mudunhu uye pasi rose. Chirevo ichi chinosimbisa zvakabuda izvo masayendisiti anga achifanotaura kweanenge makore gumi nehafu apfuura.   

Tiri kutoona shanduko dzinokurumidza mukudzika kwenyanza, tembiricha nekemesitiri, uye nemamiriro ekunze ari kuwedzera kunyanyisa pasi rose. Uye, tinogona kuva nechokwadi chekuti imwe shanduko inogona kuitika-kunyangwe isu tisingakwanisi kuyera mhedzisiro. 

Kunyanya, gungwa riri kuwedzera kudziya, uye gungwa repasi rose riri kuwedzera.

Shanduko idzi, dzimwe dzacho dzichaparadza, hadzichadzivisiki. Zviitiko zvekupisa zvakanyanya zvinogona kuuraya macoral reef, shiri dzegungwa dzinotama uye hupenyu hwemugungwa-sezvo kuchamhembe kwakadziva kumadokero kweUnited States kwakadzidza kumutengo wayo muzhizha rino. Nehurombo, zviitiko zvakadaro zvakapetwa kaviri kubva kuma1980.  

Maererano nemushumo, pasinei nezvatinoita, mwero wegungwa ucharamba uchikwira. Muzana remakore rapfuura, mazinga emakungwa akakwira avhareji ye8 inches uye mwero wekuwedzera wakawedzera zvakapetwa kaviri kubva muna 2006. Munyika yose, nharaunda dziri kusangana nezviitiko zvakawanda zvemafashamo nekudaro kuwedzera kwekukurwa nekukuvadza kune zvivakwa. Zvakare, sezvo gungwa richiramba richidziya, mazaya echando muAntarctica neGreenland angangonyungudika nekukurumidza kupfuura zvaari kutoita. Kudonha kwavo kunogona kubatsira kusvika kune mamwe mafiti matatu kusvika pakukwira kwegungwa.

Sevamwe vandinoshanda navo, ini handisi kushamiswa nemushumo uyu, kana nebasa redu revanhu mukukonzera njodzi yemamiriro ekunze. Nharaunda yedu yakaona izvi zvichiuya kwenguva yakareba. Zvichienderana neruzivo rwanga rwuripo, Ndakanyevera nezvekuputsika yeAtlantic Ocean's Gulf Stream "conveyor belt," mumushumo wa2004 kune vandinoshanda navo. Sezvo pasi richiramba richidziya, tembiricha yemugungwa iri kudzikamisa aya akakosha egungwa reAtlantic anobatsira kudzikamisa mamiriro ekunze muEurope, uye ari kuita mukana wekudonha nekukasika. Kuputsika kwakadaro kungangoita kuti kamwe kamwe kubvisire Europe kudziya kuri pakati nepakati kwegungwa.

Zvakadaro, ndinotyisidzirwa nemushumo weIPCC wazvino, nekuti unosimbisa kuti tiri kuona kukurumidza uye kunyanyisa mhedzisiro kupfuura yataitarisira.  

Nhau dzakanaka ndedzekuti tinoziva zvatinofanira kuita, uye pachine hwindo pfupi rekumisa zvinhu kuti zvisanyanya kuipa. Tinogona kuderedza kubuda, kuenda kune zero-carbon simba masosi, kuvhara zvakanyanya kusvibisa simba zvivako, uye tevera blue carbon kudzorerwa kubvisa kabhoni mumhepo uye kuifambisa mune biosphere - iyo yekusazvidemba net-zero zano.

Saka ungaitei?

Tsigira kuedza kuita shanduko padanho remitemo yenyika nepasi rose. Semuenzaniso, magetsi ndiwo anonyanya kubatsira pasi rose mukuburitswa kwegasi regreenhouse, uye ongororo dzichangobva kuitika dzinoratidza kuti makambani mashoma mashoma ndiwo anokonzera huwandu hwehutsi muUS Pasi rose, 5% chete yezvicherwa zvefossil magetsi zvinoburitsa zvinodarika makumi manomwe muzana. ma<em>greenhouse magasi—izvo zvinoita sechinangwa chisingadhuri. Tsvaga kunobva magetsi ako uye bvunza vako vanoita sarudzo kuti vaone zvingaitwe kusiyanisa masosi. Funga nezve maitiro aungaita kuderedza simba rako rekutsika uye kutsigira kuedza kudzoreredza yedu yakasikwa kabhoni inonyura-gungwa ndiro mubatsiri wedu mune izvi.

Mushumo weIPCC unotsinhira kuti iye zvino yava nguva yokuderedza migumisiro yakakomba yokuchinja kwemamiriro okunze, kunyange patinodzidza kujairana nokuchinja kwave kutoitika. Nharaunda-yakavakirwa chiito inogona kuva iyo yakawanda mhedzisiro yekuchinja kukuru. Tese tiri mune izvi pamwe chete.
