I-Arctic Ocean Acidification Workshop

I-Arctic UMark J. SpaldingOctober 11, 2016

NgoSepthemba 2016, umkhumbi omkhulu kunawo wonke owake wenza i-Northwest Passage unqamula e-Arctic wafika eNew York ngokuphepha ngemva kwezinsuku ezingu-32, izigidi zamarandi kulungiselelwa, kanye nokuphefumula okukhulu okuvela kubo bonke ababekhathazeke ngokuthi noma iyiphi ingozi izodala umonakalo ongenakulungiseka. kunendlela uqobo lwayo kuleyo ndawo esengozini. NgoSepthemba 2016, siphinde sathola ukuthi iqhwa lasolwandle selihlehle laze lafika ezingeni eliphansi kunawo wonke. Ngomhla zingama-28 kuSepthemba, i-White House isingathe uNgqongqoshe wokuqala wezesayensi wase-Arctic oklanyelwe ukwandisa ukusebenzisana okuhlangene okugxile kusayensi ye-Arctic, ucwaningo, ukubhekwa, ukuqapha, kanye nokwabelana ngedatha.

Ekuqaleni kuka-Okthoba, uMkhandlu wase-Arctic wahlangana ePortland, eMaine, lapho ukuvikelwa kwemvelo kanye nentuthuko esimeme (okuhlanganisa nokushintsha kwesimo sezulu kanye nokuqina; ikhabhoni emnyama ne-methane; ukuvimbela nokusabela kokungcoliswa kukawoyela; kanye nokubambisana kwesayensi) kwakuyisihloko sezingxoxo.

Ukweseka umsebenzi woMkhandlu wase-Arctic kanye nezinye izithakazelo zase-Arctic, siye kwezinye izinkundla zokucobelelana ngolwazi ezintathu zase-Arctic—eyodwa emayelana ne-acidification yolwandle, enye ingesikhathi esidlule nekusasa sokuphatha ngokubambisana ukudotshwa kwemikhomo, kanye

Umhlangano we-Governing Across the Waves e-Bowdoin College, eMaine

Konke lokhu kuhlanganisa noshintsho olukhulu nolusheshayo emiphakathini yabantu kanye namakhulu eminyaka emisebenzi yamasiko nezomnotho eyayincike emijikelezweni yesimo sezulu esizinzile, engaguquki uma kuqhathaniswa, ukufuduka kwezilwane, nezinye izinhlelo zemvelo. Isayensi yethu yasentshonalanga ibhekene nenkinga yokuthi singakuqonda kanjani esikubonayo. Ulwazi lwendabuko lwendawo yemvelo nalo luqhamuka nenselelo. Ngezwa abadala bezwakalisa ukukhathazeka ngokuthi babengasakwazi ukufunda iqhwa ukuze bazi ukuthi kuphephile kuphi ukuzingela. Ngabazwa bethi i-permafrost yefemu enokwethenjelwa eyayisekela izakhiwo nezokuthutha ithambile kakhulu unyaka ngamunye, isongela amakhaya abo namabhizinisi. Ngabazwa bechaza ukuthi ama-walrus, izimvu zamanzi, imikhomo, nezinye izinhlobo zezilwane ezithembele kuzo ukuze ziphile sezishintshela ezindaweni ezintsha nezindlela zokufuduka, njengoba izilwane zilandela ukufuduka kokudla kwazo. Ukuvikeleka kokudla emiphakathini yabantu nezilwane ngokufanayo kuba yingozi kakhulu ezifundeni ezisenyakatho zomhlaba.

Abantu base-Arctic ababona abashayeli abayinhloko balolu shintsho. Bayizisulu zokukhishwa kwekhabhoni okuvela ezimbonini zawo wonke umuntu, izimoto kanye nezindiza. Kungakhathaliseki ukuthi senzani kuleli qophelo, i-Arctic ecosystem izoqhubeka noshintsho olukhulu. Imiphumela eqondile nengaqondile ezilwaneni nakubantu mikhulu. Abantu basesifundeni sase-Arctic bathembele olwandle njengabantu baseziqhingini ezishisayo—mhlawumbe kakhulu njengoba bengakwazi ukuphishekela ukudla izinyanga zonyaka futhi kufanele kuthathwe inala yezinkathi ezithile zonyaka futhi igcinwe.

Le miphakathi edlangile yase-Alaska iphambili ekushintsheni kwesimo sezulu futhi nokho sonke asikuboni ngempela noma sikuzwa. Kwenzeka lapho abantu ngokuvamile bengabelani ngeqiniso labo usuku nosuku ku-inthanethi noma kwabezindaba. Futhi, njengamasiko okuziphilisa anabantu abambalwa uma kuqhathaniswa, izinhlaka zawo zomnotho aziboleki ekulinganisweni kwethu kwesimanjemanje. Ngakho-ke, asikwazi ukukhuluma nomnikelo wezomnotho abawenzayo e-US njengesizathu sokusindisa imiphakathi yabo—enye yezizathu ezimbalwa zokutshala imali ekuzivumelaniseni nezimo kanye namasu okuqina abakhokhi bentela abacelwa ukuba bawenze eFlorida, eNew York, nakwamanye asogwini. amadolobha. Izigidi azitshalwa emiphakathini yase-Alaska yamakhulu eminyaka abantu abaphila namasiko abo achazwa ngokuzivumelanisa nezimo nokuqina—izindleko ezicatshangelwayo nokuntuleka kwezixazululo eziphelele kuthikameza ukuqaliswa kwamasu amakhulu, abanzi.

Ukuzivumelanisa nezimo kudinga ukuqashelwa kwesidingo sokukhathazeka ngekusasa, kodwa futhi kudinga izizathu zethemba, nokuzimisela ukushintsha. Abantu base-Arctic sebevele bazivumelanisa nezimo; abanakho ukunethezeka kokulinda ulwazi oluphelele noma inqubo esemthethweni. Abantu base-arctic bagxile kulokho abangakubona, kodwa nokho bayakuqonda ukulimala okuqondile kwewebhu okuvela ekufakweni kwe-asidi olwandle kungase kusabise ngendlela efanayo nakuba kungase kungabonakali ngeso. Futhi yithina sonke okufanele sihloniphe ushintsho olusheshayo oluqhubekayo futhi singanyusi ubungozi esifundeni ngokujaha ukunweba imisebenzi engase ibe yingozi njengokumba uwoyela negesi, umkhumbi owandisiwe, noma uhambo lwemikhumbi olunethezekile.

I-Arctic inkulu, iyinkimbinkimbi futhi iyingozi kakhulu ngoba noma yini ebesicabanga ukuthi siyazi mayelana namaphethini ayo ishintsha ngokushesha. Ngandlela-thile, isifunda sase-Arctic siyindawo yethu yokonga amanzi abandayo—indawo engase ibe khona isiphephelo nokuzivumelanisa nezilwane ezibalekela amanzi ashisa ngokushesha asezindaweni eziningi eziseningizimu.
Kufanele senze ingxenye yethu ukuthuthukisa ukuqonda ukuthi lezi zinguquko zibathinta kanjani abantu bakhona namasiko kanye nomnotho wabo. Ukuzijwayeza kuyinqubo; ingase ingabi umugqa futhi ingabi khona umgomo owodwa—ngaphandle nje kokuvumela imiphakathi ukuthi ithuthuke ngesivinini esingaphazamisi imiphakathi yayo.

Kudingeka sihlanganise isayensi nobuchwepheshe bethu obuthuthuke kahle nolwazi lwendabuko nolwendabuko kanye namathuluzi esayensi yezakhamizi ukuze sibheke izixazululo zale miphakathi. Kudingeka sizibuze: Imaphi amasu okuzivumelanisa nezimo azosebenza e-Arctic? Singakwazisa kanjani lokho abakwazisa ngezindlela ezisekela inhlalakahle yabo?
