Zinsinsi za Ocean

Nyanja ili ndi chinsinsi.

Ndine wamwayi kwambiri kugwira ntchito pazaumoyo wam'nyanja. Ndinakulira m'mudzi wa Chingerezi wa m'mphepete mwa nyanja, ndipo ndinakhala nthawi yambiri ndikuyang'ana nyanja, ndikudabwa ndi zinsinsi zake. Tsopano ndikugwira ntchito kuti ndiwasunge.

Nyanja, monga tikudziwira, ndiyofunikira kwa moyo wonse wodalira mpweya, inu ndi ine kuphatikiza! Koma moyo ndi wofunikanso panyanja. Nyanja imatulutsa mpweya wochuluka chifukwa cha zomera za m’nyanja. Zomera izi zimatulutsa mpweya woipa (CO2), mpweya wowonjezera kutentha, ndikuwusintha kukhala shuga wopangidwa ndi mpweya ndi mpweya. Ndi ngwazi zakusintha kwanyengo! Panopa pali kuzindikira kwakukulu kwa ntchito ya moyo wa m'nyanja pochepetsa kusintha kwa nyengo, palinso mawu akuti: blue carbon. Koma pali chinsinsi… Zomera za m'nyanja zimatha kutsitsa mpweya wa CO2 monga momwe zimachitira, ndipo nyanja zam'madzi zimatha kusunga mpweya wochuluka monga momwe zimasungira, chifukwa cha nyama za m'nyanja.

Mu April, pa chilumba cha Pacific cha Tonga, ndinali ndi mwayi wofotokoza chinsinsi chimenechi pamsonkhano wakuti “Anangumi mu Nyanja Yosintha.” M'zilumba zambiri za Pacific, anamgumi amathandizira pazachuma zokopa alendo, ndipo ndizofunikira pachikhalidwe. Ngakhale kuti tikukhudzidwa moyenerera ndi zotsatira za kusintha kwa nyengo pa anamgumi, tiyeneranso kuzindikira kuti anamgumi angakhale othandiza kwambiri polimbana ndi kusintha kwa nyengo! Kupyolera m'madzi awo akuya, kusamuka kwakukulu, kutalika kwa moyo wautali, ndi matupi akuluakulu, anamgumi ali ndi gawo lalikulu pachinsinsi cha nyanjayi.

Anangumi onse amathandizira kuti zomera za m'nyanja zigwere pansi CO2, komanso zimathandiza kusunga mpweya m'nyanja. Choyamba, amapereka zakudya zofunika zomwe zimathandiza kuti zomera za m'nyanja zikule. Nsomba za namgumi ndi feteleza, zomwe zimabweretsa zakudya kuchokera pansi, kumene anamgumi amadyera, pamwamba, kumene zomera zimafunikira zakudya izi kuti photosynthesis. Anangumi osamukasamuka amabweranso ndi zakudya zochokera kumalo odyetserako zokolola zambiri, ndikuzimasula m'madzi opanda mchere a malo omwe anamgumi amaswana, zomwe zimapangitsa kukula kwa zomera za m'nyanja kudutsa nyanja.

Chachiwiri, anamgumi amasunga mpweya wa carbon mu nyanja, kunja kwa mlengalenga, kumene ukhoza kuthandizira kusintha kwa nyengo. Zomera zing'onozing'ono zam'nyanja zimatulutsa shuga wopangidwa ndi kaboni, koma zimakhala ndi moyo waufupi kwambiri, kotero sizingathe kusunga kaboni. Akafa, kaboni yambiri imatulutsidwa m'madzi a pamwamba, ndipo imatha kusinthidwa kukhala CO2. Koma anamgumiwo amatha kukhala ndi moyo kwa zaka zopitirira 2, akumadya zakudya zimene zimayamba ndi shuga wa m’zomera ting’onoting’onozi, n’kumaunjikira mpweya wa carbon m’matupi awo akuluakulu. Anangumi akamwalira, zamoyo za m'nyanja yakuya zimadya mabwinja awo, ndipo mpweya womwe poyamba unkasungidwa m'matupi a anamgumi ungalowe mumatope. Mpweya wa kaboni ukafika pamatope a m'nyanja yakuya, umatsekedwa bwino, choncho sungathe kuyendetsa kusintha kwa nyengo. Mpweya uwu sungathe kubwereranso ngati COXNUMX mumlengalenga, mwina kwa zaka zikwizikwi.

Kodi kuteteza anamgumi kungakhale mbali ya njira yothetsera kusintha kwa nyengo? Chithunzi: Sylke Rohrlach, Flickr

Popeza zilumba za Pacific zimathandizira kagawo kakang'ono kwambiri pakutulutsa mpweya wowonjezera kutentha komwe kumayambitsa kusintha kwanyengo - osakwana theka la 1%, kwa maboma a Pacific Island, kupeza moyo wabwino ndikuthandizira ku chilengedwe chomwe anamgumi amapereka ngati sink ya kaboni ndi ntchito yothandiza. zingathandize kuthana ndi vuto la kusintha kwa nyengo kwa anthu a zilumba za Pacific, chikhalidwe ndi malo. Ena tsopano akuwona mwayi wophatikizira kuteteza anamgumi muzopereka zawo ku United Nations Framework Convention on Climate Change (UNFCCC), ndikuthandizira kukwaniritsa zolinga za UN Sustainable Development Goals (SDGs), zonse zazinthu zam'madzi (SDG 14), komanso zachitukuko. zochita pakusintha kwanyengo (SDG 13).

Maiko angapo a Zilumba za Pacific ali kale atsogoleri posamalira anangumi, atalengeza kuti m'madzi awo muli malo osungira anangumi. Chaka chilichonse, anamgumi akuluakulu a humpback amacheza, kuswana, ndi kubereka m'madzi a pachilumba cha Pacific. Anangumi amenewa amagwiritsa ntchito njira zosamuka kudutsa m’nyanja zikuluzikulu, kumene satetezedwa, kuti akafike kumene amadyera ku Antarctica. Kumeneko amatha kupikisana ndi gwero lawo loyamba la chakudya, krill, ndi zombo za usodzi. Antarctic krill imagwiritsidwa ntchito kwambiri podyetsa ziweto (zamadzi, ziweto, ziweto) komanso nyambo za nsomba.

Ndi UN sabata ino kuchititsa msonkhano woyamba wa Ocean pa SDG 14, ndi ndondomeko ya UN yopanga mgwirizano walamulo pa zamoyo zosiyanasiyana m'nyanja zikuluzikulu zomwe zikuchitika, ndikuyembekeza kuthandizira zilumba za Pacific kuti zikwaniritse zolinga zawo kuzindikira, kumvetsetsa, ndi kuteteza udindo wa anamgumi pochepetsa kusintha kwa nyengo. Ubwino wa utsogoleri uwu kwa anamgumi onse ndi okhala pachilumba cha Pacific udzafikira ku moyo wa anthu ndi nyanja padziko lonse lapansi.

Koma chinsinsi cha nyanja chimazama kwambiri. Si anamgumi okha!

Kafukufuku wochulukirachulukira akulumikiza moyo wa m'nyanja ndi kugwidwa ndi kusungidwa kwa kaboni zomwe ndizofunikira pakumira kwa carbon carbon, komanso kuti zamoyo zapamtunda zithane ndi kusintha kwa nyengo. Nsomba, akamba, shaki, ngakhale nkhanu! Onse ali ndi maudindo muchinsinsi cholumikizidwa modabwitsa ichi, chodziwika pang'ono cha nyanja yamchere. Sitinangokanda pamwamba.

Njira zisanu ndi zitatu zomwe nyama zam'nyanja zimathandizira pampu ya carbon. Chithunzi chochokera ku Nsomba Carbon lipoti (Lutz ndi Martin 2014).

Wolembayo akufuna kuvomereza Fonds Pacifique ndi Curtis ndi Edith Munson Foundation kuti athe kupanga lipoti la anamgumi a chilumba cha Pacific ndi kusintha kwa nyengo, komanso, pamodzi ndi GEF / UNEP Blue Forests Project, kuthandizira kupezeka ku Whales mu Changing Ocean. msonkhano.
