Leonardo diCaprio to tuto http://watchdocumentaries.com/before-the-flood/ od 1:17.55 vysvetloval takto:
ked sa zvysi teplota Golfskeho prudu, ten dorazi do Arktidy teplejsi a rozpusti viac ladovca, cim sa stihne v tom studenom s ladom namichanom oceane stratit a nedorazi dostatocne teply ku Britanii. Preto je nezvycajna zima v nezvycajnom case v Europe ukazkou globalneho oteplenia.
Ked sa ale vplyvom prehrievania Golfsky prud odkloni uplne inam, prestane zohrievat ladovec v Arktide a tipujem ze uz nebude mat Europu co ochladzovat.

Tu to vidno pekne:
