Chidzidzo chitsva chakaratidza kuti chimwe chezvakanyanya kukosha zveWorld of the World Ocean - Atlantic meridional kutenderera (amoc) Polar mvura Atlantic uye nokudaro kubatsira pasi kuti utongere kupisa - kwasvikira kwakanyanya kushaya simba kweMireniyumu. Uye kugoverwa kunoshamisa kwekupisa kwepasi kwaive kusakosha.
Masayendisiti kubva kuIrish National University mukugadziriswa, University College of London (German Yunivhesiti Basa ravo rinobudiswa mune chinyorwa chechisikigo geoscience.
Sezvo, sezvambotaurwa pamusoro apa, kutenderera kwemvura muAtlantic kusimbisa kupisa kuchamhembe, kunozviratidza mumamiriro ekunze, uye pasina chando ichi mune imwe nguva seUK inogona kunge iri angangoita 5 ° C Colder. Icho chokwadi chekuti kudziya kwepasirese kunotonhora kuAtlantic Flow glf rwizi chikamu cheiyomoc, yave ichizivikanwa kare. Muna 2018, boka rimwe chete remasayendisiti rakazivisa kuti kumhanya kwegorofu rwizi kwakawira pasi pane iyo nhoroondo yese yekuona uye mune ramangwana iri rinogona kupera zvachose. Zvinoenderana nedata ravo rekupedzisira, iyo Atlantic meridional kutenderera pachayo kubva pakati pezana ramakumi maviri yezana yakapera simba neanosvika gumi nemashanu muzana.
"Kekutanga patakasiyana chiverengero chezvidzidzo zvakapfuura uye ndikawana kuti vanopa mhinduro isingaperi yeMamoc Evolution kwemakore 1600," akadaro Dr St. Stefan Ramstorf, nzvimbo inyunivhesiti yePotsdam yunivhesiti. - Mhedzisiro yacho yakaratidza kuti kutenderera kwacho kwaive kwakasimba kusvika pakupera kwezana reXix. Asi nekuzara kweiyo nguva diki yegreen, munenge muna 1850, gungwa rakatanga kuderera, uye kubva pakati pezana ramakumi maviri, kubva pamakumi matanhatu, yechipiri, kuderera kwakapinza kwakateverwa. Kudzoreredza kushoma kwekutenderera kwakaitika ipapo muma1990, asi ipapo kuderera kwakaitika mumakore gumi ekutanga a2000. "
Iyo huru kubudirira kwebasa ndeyekuti yakasanganiswa mhando dzakasiyana dzemamiriro ekunze "zvisina kujairika data" kuti uongorore amoc shanduko. Ehe, mhedzisiro inofanira kungwarira nokungwarira, kunyanya sezvo zvikonzero zvekuita zvekusanyengera kwekuparadzirwa kweAtlantic hazvina kudzidza zvakanyatsonerwa.
Nekudaro, sezvo zvidzidzo zvakapfuura zvakaratidza, shanduko yemamiriro ekunze, inogona kubatsira mukushayiwa kweanoyerera kwegungwa, zvichikonzera kucheneswa kwechando munzvimbo dzakakwirira dzekuchamhembe. Kunyungudika kwechando kunounza matsva emvura mumakungwa - uye inokanganisa kutenderera kwakajairika mumakungwa. Nekuda kweizvozvo, kana kudziya kwepasirese kuchapfuurira kusvika pakupera kwezana reXXI (sezvatinonzwisisa izvi, chiitiko ichi hachisisipo), "
Sekureva kwemasayendisiti, kunonoka kwekutenderera kwemvura kwakatocherechedzwa mumamiriro ekunze emativi emativi ese eAtlantic Ocean. Sezvo kuyerera kwemahombekombe eEast kunotora simba, mvura yakawanda inogona kuunganidza, iyo ichatungamira mukuwedzera kusimbiswa kwedanho regungwa, semuenzaniso, pedyo neNew York neBoston.
Panguva imwecheteyo, Europe inotarisana nemafungu ekupisa. "Kunyanya, kupisa kwakawanda muzhizha kwa2015 kwakabatana neyekuchengeterwa kuchamhembe kweiyo Atlantic Ocean mugore rimwe chete - iyi yaizoita kuti isimbe nekuda kwekutonhora kwekuchamhembe kwe Atlantic inobatsira kuumbwa kwekumanikidzwa kwemhepo, iyo inotungamira mweya inodziya kubva kumaodzanyemba kuEurope, "vanyori vebasa rakatsanangurwa.
