Gulf Stream wayeka: Iyinyaniso Okanye Bubuxoki?

Ngo-2010, uluntu lwamazwe ngamazwe izanyazanyiswa iindaba ukuba kwixa elizayo oko sisiqalo Ice Age entsha kunokwenzeka. Gianluigi Zangari yamachiza Italian, National Institute of Nuclear Physics e Frascati, wenza ingxelo ivuso, "i-Gulf Stream wayeka!" Oku kuza data ukuhlaziya Isazinzulu efunyenwe kwiisathelayithi kokuma iziganeko esesibhakabhakeni kunye bolwandle Gulf of Mexico.

Ngokutsho sisazinzulu Italian, ngexesha Gulf Stream wayeka ngenxa yokubhuqiswa intlekele eziphilayo kule ndawo. Kwaqengqeleka iinyanga ezininzi chibi Horizon Inkxalabo kakuhle «British Petroleum» kwi amanzi kweoli Gulf kwenzeka ekrwada. ziqhume nje malunga nezigidi ezibini, anamanci eelitha lunezinto zakheka ezantsi kwe uhlobo "mlilo ioli". Iinkokheli Group "BP" kunye norhulumente US wazama ukufihla oku ngokulahla e Mexico iilitha ezimalunga nezigidi ezibini wesinyibilikisi Bay "Corexit" yaye zininzi ezinye dispersants ukuze ukucinezela hydrocarbon. Yokungenelela imiphumo ntlekele akakwazanga ukufumana kuphela ukufihla umlinganiselo umonakalo - yinxalenye ibheyi ukusuka umboniso oyile isusiwe, kodwa ukujula okukhulu ukususa ioli ayinakwenzeka. A nokulandelelana ioli ukuvuza ezingenakulungiswa kukuba ubushushu ezitshintshileyo, viscosity kunye etyuwa kwamanzi olwandle, nto leyo imida liwa, phakathi kweengqimba yamanzi abandayo nefudumeleyo, ngenxa yokuba lo imisinga kancinci kwamanzi, kwaye kwezinye iindawo le Gulf Stream zanqunyanyiswa kwaphela. Konke oku zabangela Zangari athethe ngolo hlobo.

Yintoni Gulf Stream? Kubalulekile ukuba nobubele Earth, owenza iimeko zemozulu kwiindawo ezikufutshane lweAtlantiki imimandla. Wenza ke kumazwe Scandanavia yokuhlala yaye ligcina nemozulu efudumeleyo eYurophu. Ke ukuba Gulf Stream wayeka, silindele ukuba ekuqaleni i-Ice Age. Okokuqala, ice wayifulela iBritani kunye Ireland, Northern States of America kunye Canada, ilandelwe snap elibukhali ebandayo iya kukugubungela Intshona Melika, eYurophu Asia. Abantu baya kunyanzeleka ukuba iya ku kwiindawo ezifudumeleyo. Cold, ukufuduka, ukusilela kwezityalo kwaye, ngenxa yoko, indlala iya kukhokelela ekutshabalaleni malunga esithathwini-zalo lonke uluntu.

Ngo-2010, i-nzulu abangakholwayo lweentsingiselo self-ephilisa izifo, njengoko kuyakrokreleka evuzayo oyile kuyaqhubeka. Kodwa emva kwethutyana imifanekiso satellite zifunyenwe ngaphandle kokuqinisekisa ukuba Gulf Stream wayeka. Xa iifoto kwendawo yonke wayebona ukuba North Atlantic kwakhona ethwala amanzi efudumeleyo yayo kwindlela eqhelekileyo.

Ngoko ke, le ntlekele ihlabathi jikelele imisiwe? Lo mbuzo akukho impendulo enye. Izazinzulu zithi ukuba Gulf Stream wayeka okwethutyana iintsuku eziliqela, imeko efanayo ngo-2004, yaye akukho iziphumo ezibi ukuba ingalandelwa uMhlaba. Kodwa abaxhasi a nkolelo iyelenqe jikelele athi yonke imifanekiso Gulf of Mexico kwiisathelayithi emva 2010 fake. Imozulu uyatshintsha, kodwa kancinci, ngokuba amanzi Gulf Stream sifudumele ngokupheleleyo, yaye ukuba lungapholi womhlaba wonke kwiminyaka embalwa ubudala.
