Gulf Ukusakaza kumisiwe: Iqiniso Noma Indaba Eqanjiwe?

Ngo-2010, umphakathi wamazwe omhlaba onyakaziswa izindaba esikhathini esizayo esiseduze kungenzeka ekuqaleni a Ice Age entsha. physics Italian Gianluigi Zangari, National Institute of Nuclear Physics e Frascati, wenza isitatimende ukuthusa: "Gulf Stream wayeka!" Lezi ziphetho ukuza usosayensi idatha ukuhlaziya etholakele iziphuphutheki kokuma imihlola emkhathini futhi olwandle eGulf of Mexico.

Ngokusho usosayensi wase-Italy, phakathi Gulf Ukusakaza kumisiwe ngenxa emikhulu nhlekelele emvelweni kule ndawo. Kwaphela izinyanga eziningana we Deepwater Horizon kahle Ukukhathazeka «British Petroleum» emanzini Gulf uwoyela imidlalo iphutha ongahluziwe. Ngathulula yonke mayelana amalitha ayizigidi ezingu ezingamakhulu amabili izinto akhiwa ezansi uhlobo "uwoyela mlilo". Abaholi Iqembu "BP" futhi uhulumeni wase-US wazama ukufihla leli qiniso ngokuphonsa eMexico amalitha ayizigidi ezimbili kuphela Bay "Corexit" futhi eziningi nezinye dispersants ukuze sinqobe hydrocarbon. Iwukudambisa imiphumela le nhlekelele ayikwazanga kuphela uthole ukufihla sezingeni ukulimala kweqiniso - ingxenye bay kusukela ifilimu uwoyela ususuliwe, kodwa ukujula okukhulu ukususa amafutha akunakwenzeka. A umphumela iyona ukuvuza uwoyela ungalungiseki ukuthi zishintshile lokushisa, viscosity futhi usawoti lamanzi olwandle, kuphumele imingcele kubhidlika phakathi izingqimba amanzi abandayo kanye afudumele, ngenxa yaleli imisinga kancane kwamanzi, futhi kwezinye izindawo Gulf Stream wayeka ngokuphelele. Konke lokhu utshelwa Zangari lasho amazwi anjalo.

Kuyini Gulf Stream? Kubalulekile ofudumele Earth, esiyingxenye izimo sezulu ezindaweni ezakhelene Atlantic izindawo. Wenza emazweni aseScandinavia habitability iphinde igcine isimo sezulu esifudumele eYurophu. Futhi uma Gulf Stream wayeka, silindele ukuqala Ice Age. Okokuqala, u-ice embozwe kweBrithani ne-Ireland, Northern States of America nase-Canada, kulandelwa snap ebandayo abukhali utawufaka eNyakatho Melika, eYurophu nase-Asia. Abantu ziyophoqeleka ukuba uthuthele ku izindawo ezifudumele. Kuyabanda, ukufuduka, isitshalo ukwehluleka, ngenxa yalokho, indlala kuzoholela ukushabalala abangaba izingxenye ezimbili kwezintathu zabantu bonke.

Ngo-2010, usosayensi akakholelwa izitayela self-ephulukisa, njengoba esolwa uwoyela ukuvuza uyaqhubeka. Kodwa emva kwesikhashana nezithombe zesiphuphutheki zazitholakala ngaphandle kokuqinisekisa ukuthi Gulf Ukusakaza kumisiwe. Esikhathini izithombe yonke wayebona ukuthi zamanje eNyakatho ye-Atlantic futhi athwala amanzi awo afudumele emzileni evamile.

Ngakho lokho, lo inhlekelele ezweni global ikhanseliwe? Lo mbuzo asikho impendulo eyodwa. Ososayensi bathi Gulf Ukusakaza kumisiwe okwesikhashana izinsuku eziningana, nesimo esifanayo kwaba ngo-2004, futhi akukho nemiphumela emibi uma asilandelwanga uMhlaba. Kodwa abasekeli uzungu theorists global baphikisa ngokuthi zonke izithombe eGulf of Mexico, kumasathelayithi emva 2010 inkohliso. Isimo sezulu uyashintsha, kodwa kancane, ngoba amanzi Gulf Stream ongakabi selupholile ngokuphelele, futhi indlu somhlaba wonke saba khona eminyakeni embalwa.
