Msonkhano wa Arctic Ocean Acidification

Arctic Mark J. SpaldingOctober 11, 2016

Mu Seputembala 2016, sitima yapamadzi yayikulu kwambiri yomwe idapangapo Northwest Passage kudutsa Arctic idafika ku New York mosatekeseka patatha masiku 32. kuposa njira yokhayo yodutsa m'malo osatetezekawo. Mu Seputembala 2016, tidamvanso kuti madzi oundana a m'nyanja adatsika kwambiri kuposa kale lonse. Pa Seputembara 28, White House idakhala ndi Unduna woyamba wa Sayansi ya Arctic wopangidwa kuti uwonjezere mgwirizano womwe umayang'ana pa sayansi ya Arctic, kafukufuku, zowonera, kuyang'anira, ndi kugawana deta.

Kumayambiriro kwa mwezi wa October, bungwe la Arctic Council linakumana ku Portland, Maine, kumene chitetezo cha chilengedwe ndi chitukuko chokhazikika (kuphatikizapo kusintha kwa nyengo ndi kupirira; mpweya wakuda ndi methane; kupewa ndi kuyankha kuipitsidwa kwa mafuta; ndi mgwirizano wa sayansi) inali nkhani ya zokambirana.

Pochirikiza ntchito ya Arctic Council ndi zokonda zina za ku Arctic, tinapezeka pamisonkhano ina yowonjezereka ya Arctic—imodzi yokhudza acidification ya m’nyanja, ina ya m’mbuyomu ndi yamtsogolo yosamalira limodzi ntchito yoweta anamgumi, ndi

Msonkhano wa Governing Across the Waves ku Bowdoin College, Maine

Zonsezi zimawonjezera kusintha kwakukulu ndi kofulumira kwa madera a anthu ndi zaka mazana a zochitika za chikhalidwe ndi zachuma zomwe zimadalira nyengo yokhazikika, yosasinthika, kusamuka kwa nyama, ndi machitidwe ena achilengedwe. Sayansi yathu yakumadzulo ikulimbana ndi momwe tingamvetsetse zomwe tikuwona. Chidziwitso cha chikhalidwe cha chikhalidwe cha chilengedwe chikubweranso chotsutsa. Ndinamva akulu akudandaula kuti sangathenso kuwerenga ayezi kuti adziwe komwe kuli kotetezeka kusaka. Ndinawamva akunena kuti malo odalirika a permafrost omwe amathandiza nyumba ndi zoyendera ndi zofewa kwambiri chaka chilichonse, ndikuwopseza nyumba zawo ndi malonda. Ndinawamva akufotokoza kuti ma walrus, zidindo, anamgumi, ndi zamoyo zina zimene amadalira pa moyo wawo zikusamukira ku malo atsopano ndi mmene zimasamuka, pamene nyamazo zikutsatira kusamuka kwa chakudya chawo. Kutetezedwa kwa chakudya kwa anthu ndi nyama mofanana kukuvuta kwambiri kumadera onse a kumpoto kwa dziko lapansi.

Anthu a ku Arctic si amene ayambitsa kusinthaku. Ndiwo omwe amazunzidwa ndi mpweya wochokera ku mafakitale a wina aliyense, magalimoto ndi ndege. Ziribe kanthu zomwe tingachite pakadali pano, zachilengedwe za ku Arctic zipitilira kusintha kwambiri. Zotsatira zachindunji ndi zosalunjika pa zamoyo ndi anthu ndi zazikulu. Anthu a m’chigawo cha Arctic amadalira nyanja mofanana ndi anthu a m’zilumba za m’madera otentha—mwinamwake kwambiri chifukwa chakuti sangathe kufunafuna chakudya kwa miyezi ingapo ya chaka ndipo kuchuluka kwa nyengo kuyenera kutengedwa ndi kusungidwa.

Madera amphamvu awa aku Alaska ali patsogolo pakusintha kwanyengo koma enafe sitikuwona kapena kumva. Zikuchitika pamene anthu nthawi zambiri sagawana zenizeni zawo tsiku lililonse pa intaneti kapena m'ma TV. Ndipo, monga zikhalidwe zopezera ndalama zomwe zili ndi anthu ochepa, momwe chuma chawo chimakhalira sichikugwirizana ndi zomwe timawerengera zamakono. Chifukwa chake, sitingathe kuyankhula ndi thandizo lazachuma lomwe amapereka ku US ngati chifukwa chopulumutsira madera awo-chimodzi mwa zifukwa zochepa zopezera ndalama kuti athe kusintha ndi kulimba mtima njira zomwe okhometsa msonkho akufunsidwa kuti azichita ku Florida, New York, ndi m'mphepete mwa nyanja. mizinda. Mamiliyoni sakusungidwa m'madera akale a ku Alaska a anthu omwe moyo wawo ndi chikhalidwe chawo zimatanthauzidwa ndi kusintha ndi kulimba mtima-mtengo woganiziridwa ndi kusowa kwa njira zothetsera mavuto kumalepheretsa kukhazikitsidwa kwa njira zazikulu, zazikulu.

Kusintha kumafuna kuzindikira kufunika kodera nkhawa za m’tsogolo, koma kumafunanso zifukwa za chiyembekezo, ndi kufunitsitsa kusintha. Anthu aku Arctic akusintha kale; alibe mwayi wodikirira chidziwitso changwiro kapena ndondomeko yovomerezeka. Anthu aku Arctic akuyang'ana kwambiri zomwe angawone, komabe amamvetsetsa kuti kuvulaza kwapaintaneti kwazakudya kuchokera ku acidization ya m'nyanja kungakhale kowopsa ngakhale kuti sikungawonekere. Ndife tonsefe amene tiyenera kulemekeza kusintha kwachangu komwe kukuchitika osati kuonjezera chiwopsezo mderali pothamangira kukulitsa zinthu zomwe zitha kukhala zoopsa monga kubowola mafuta ndi gasi, kukulitsa zombo, kapena maulendo apanyanja apamwamba.

Nyanja ya Arctic ndi yayikulu, yovuta komanso yowopsa kwambiri chifukwa chilichonse chomwe timaganiza kuti timadziwa pamapangidwe ake chikusintha mwachangu. M'njira yakeyake, dera la Arctic ndi njira yathu yosungira madzi ozizira - malo othawirako ndi kusintha kwa zamoyo zomwe zikuthawa madzi otentha kwambiri a m'madera akumwera.
Tiyenera kuchita mbali yathu kuti timvetsetse momwe kusinthaku kukhudzira anthu ake komanso chikhalidwe chawo komanso chuma chawo. Kusintha ndi njira; sizingakhale zofananira ndipo palibe cholinga chimodzi chokha—kupatulapo kulola madera kuti asinthe zinthu mosasokoneza madera awo.

Tiyenera kuphatikizira sayansi yathu yotukuka bwino ndi chidziwitso chakwawo komanso zachikhalidwe komanso zida zasayansi za nzika kuti tipeze njira zothetsera maderawa. Tiyenera kudzifunsa kuti: Ndi njira ziti zosinthira zomwe zidzagwire ntchito ku Arctic? Kodi zinthu zimene amaona kuti n’zamtengo wapatali zingawathandize bwanji kukhala ndi moyo wabwino?
