Ramangwana Redu Rinoenderana Nesu: Antarctic mamiriro ekunze uye nharaunda

Antarctica, kondinendi yekumaodzanyemba kwePasi, imusha kune zvimwe zvinoshamisa zvepasi rose zvinoshamisa. Zvakadaro, iriwo rimwe rematunhu ari panjodzi yekusanduka kwemamiriro ekunze. Sezvo tembiricha yepasi rose iri kuramba ichikwira, kukanganisa kuAntarctica nemakungwa akaitenderedza kuchave kwakadzama. Kuratidzira izvi, Komiti yeSainzi yeAntarctic Research (SCAR) yakashanda nemasayendisiti pasi rese kugadzira Antarctic Climate Change uye Zvakatipoteredza Decadal Synopsis (ACCE). Chirevo chinopa pfupiso yemakore gumi ekutsvagisa, uye zvitsauko zvayo zvisere zvinosiya nzvimbo diki yekupokana: kondinendi yeAntarctic iri kudziya, uye ndizvo zvakaitenderedza Southern Ocean.

Kuchinja Kwemamiriro ekunze uye Antarctica

Kuchinja kwemamiriro ekunze kuri kukanganisa zvikuru mazaya echando eAntarctica, mamiriro ekunze nehupenyu, zvine mhedzisiro inosvika kure pasi rose. Chirevo cheACCE chinopa mapfupi, akaunganidzwa manzwisisiro ekunzwisisa kwazvino, kurudziro yakajeka yezviito kugadzirisa shanduko, uye kurudziro yekuwedzera tsvagiridzo. Chinhu chakakosha kuti tinzwisise kuti shanduko idzi dzinorevei kune vese Antarctic uye nepasirese - uye zvatingaite. Chirevo ichi chakatungamirwa naMonash University Purofesa Steven Chown, Director weSecuring Antarctica's Environmental Future (SAEF) uye SCAR's Immediate Past President.

Kukurukurirana Kunokosha Sayenzi

Chirevo cheACCE chakagadzirirwa 2022 Antarctic Treaty Consultative Meeting muBerlin, yakagadzirirwa kutaurirana kune Mapato eChibvumirano kuti tinoda danho nekukasira kudzikamisa kukanganisa kwepasirese kwekushanduka kwemamiriro ekunze muAntarctica neSouthern Ocean. Nekudaro, meseji yemushumo ndiyo inoda kugovaniswa zvakanyanya sezvinobvira. Kuti izvi zviitike, SCAR yakagadzira pikicha inopfupikisa mameseji akakosha kubva mushumo, ine chimiro chinobata chakagadzirirwa kusvika kune vatsva.

Tamba vhidhiyo

Iyo animation inopfupikisa kukanganisa kwekuchinja kwemamiriro ekunze munzvimbo dzakasiyana dzepasi rose, nenzira dzakabatana zvakanyanya neAntarctica neSouthern Ocean:

• Atmosphere: Kuwedzera kuwanda kwegasi regreenhouse uye tembiricha yemuchadenga kuri kukanganisa zviitiko zvemuchadenga, semafungu ekupisa, kunaya kwemvura, uye mafambiro emhepo.
• Makungwa: Gungwa reMaodzanyemba nderimwe remakabhoni makuru epasi, uye tsvakiridzo inodiwa kuti unzwisise kuti izvi zvinokanganisa sei makungwa epasi rose nemamiriro ekunze.
• Cryosphere: Izvo zvakakosha kuti unzwisise kuti Antarctic cryosphere - iyo inosanganisira aizi yegungwa, permafrost, uye masherufu echando - iri kuchinja sei mukupindura kushanduka kwemhepo negungwa.
• Chiyero cheGungwa: Iyo Antarctic Ice Sheet inobata mvura inokwana kusimudza mwero wepasi rose wegungwa nemamita makumi mashanu nemasere kana yanyungudika zvachose. Tinofanira kunzwisisa kuti ice sheet rinopindura sei kushanduka kwemamiriro ekunze uye kuti izvi zvingakanganisa sei mazinga epasi rose egungwa.
• Marine Life & Terrestrial Hupenyu: Shanduko kumamiriro ekunze eAntarctica inokanganisa marudzi anogara imomo, mazhinji acho akajairwa kunharaunda yeAntarctic. Zvisikwa zvakaita sekrill, ibwe repakona reAntarctic ecosystem, zvave kutokanganiswa nekushanduka kwemamiriro ekunze.

Ramangwana Redu Rinoenderana Nesu

Pakazere, chirevo che ACCE chiyeuchidzo chinokatyamadza chekukanganisa kwekushanduka kwemamiriro ekunze panyika yedu uye kudiwa kwekuita. Sokupedzisa kunoita mushumo wacho, “remangwana reAntarctica rine chokuita zvikuru neramangwana remamiriro okunze epasi pose, uye matambudziko ekugadzirisa kushanduka kwemamiriro ekunze achada kubatana uye kubatana zvisina kumboitika.”

Kuchinja kwemamiriro ekunze kuchave nemhedzisiro paAntarctica neSouthern Ocean, mazhinji ayo atinogona kutoona nhasi. Zvisinei, hakusati kwava kunyanyononoka kuita chiito. Isu tinofanirwa kusangana nekupfuura zvakanangwa zvekuburitsa gasi regreenhouse zveParis Climate Agreement - tozviita nekuchimbidza.

Ramangwana redu rinotsamira patiri.

Nezve SCAR

The Sayenzi Komiti yeAntarctic Tsvagiridzo (SCAR) isangano rine dingindira reInternational Science Council, uye rakasikwa muna 1958. SCAR inopihwa mhosva yekutanga, kusimudzira uye kuronga zvemhando yepamusoro tsvakiridzo yesainzi yepasi rose mudunhu reAntarctic (kusanganisira Southern Ocean), uye nezvebasa re Nzvimbo yeAntarctic muNyika system. SCAR inopa chinangwa uye yakazvimirira zano resainzi kuAntarctic Treaty Consultative Meetings nemamwe masangano akaita seUNFCCC neIPCC panyaya dzesainzi nekuchengetedza zvine chekuita nekutonga kweAntarctica neSouthern Ocean uye nezvebasa redunhu reAntarctic muNyika system.
