Carbon dioxide is the missing ingredient in explaining the advent of Ice Ages in the Northern Hemisphere and why those cold epochs have caused changes in the tropics for the past 2.7 million years. Scientists analyzed ocean sediment cores and found a definitive link between the Ice Ages and ocean surface temperatures in the tropics. They believe carbon dioxide explains the link.
