Ngesikhathi esifanayo lapho abantu, kanye nezilwane, bezama ukuzivikela emiphumeleni yokuphila esimweni sezulu esishisayo nesomile, izidalwa zezitshalo bazama nokuzivumelanisa nezimo kulesi simo esisha.
Uphenyo olushicilelwe ku »Global Chamge Biology», olwenziwe yi-University of Liverpool ngokubambisana kwe-University of Syracusa (etholakala e-United States), kuyachaza kunjani ukujwayela izitshalo ekuguqukeni kwesimo sezulu.
Eminyakeni eyi-15 eyedlule, bafunde izimpendulo ezahlukahlukene ezimweni ezahlukahlukene zesimo sezulu ezinochungechunge lwezitshalo ezivela edlelweni eliseduze kakhulu nedolobha laseBrithani iBuxton, njengesomiso esikhulu kakhulu noma imvula eningi. Umphumela waba nelukuluku kakhulu, ngoba bathola ukuthi lezi zinguquko base beguqule iDNA zezitshalo, into ochwepheshe abayibiza ngokuthi "ukutakula kokuvela kwemvelo."
URaj Whitlock, Ph.D. kanye noProfesa Wezemvelo eLiverpool University Institute for Integrative Biology, bathe iqiniso lokuthi ukuguquka kwesimo sezulu kudale izinguquko ezinhlotsheni zofuzo zezitshalo eminyakeni eyi-15 edlule kwenze kube yinto emangalisayo, ngoba imvamisa izitshalo zithatha isikhathi eside ukuzivumelanisa nezimo kuzinguquko zezulu. Ngakho-ke, lokhu kungachaza ukumelana kwezitshalo ezifundwe lapho ziphoqelelwe ukuba zikhule ngaphansi kwezimo ezithile zemvelo.
Lolu cwaningo lwenziwe eBuxton Climate Change Impact Laboratory (BCCIL), egqumeni lapho wasebenzisa isimo sezulu ngokuzama kusukela ngo-1993 ukubona ukuthi izitshalo zisabela kanjani.
Yize lesi silingo sijabulisa kakhulu, Ukuguquka kwesimo sezulu kuzoletha inselelo ebaluleke kakhulu kubantu abaningi bezitshalo, namuhla esezizama ukuzivumelanisa nesimo sezulu esiya sishintsha njalo.
