Ottawa, Ont.: Apr 13, 2006. pg. A.13. ``The turning point came after viewing a graph of 650,000 years of ice core samples. This graph appears in the global-warming article on the Wikipedia website, using well- documented data from the European Project for Ice Coring in Antarctica (EPICA). A clear correlation between rising temperatures and rising carbon dioxide levels is evident.``   00:23`
