Climate Cycles: Clues from Deep Sea Cores

What are climate cycles? The Earth's climate is cyclical - that means that there is a regular pattern of change over time. Scientific ocean drilling has been the tool in reconstructing virtually every climate record from 500,000 years ago to nearly 70 million years ago. So, deep sea cores obviously hold a lot of clues in discovering what ancient climate was like. Scientists are increasingly using different and more clever ways of reconstructing these climate records, and as the methods change and become more advanced we discover more and more of how climate change works and the potential for humans to impact the global climate system. The activities on the School of Rock website teaches about climate change on two different scales - orbital and suborbital. [School of Rock (IODP)] Grade level: 9-College.
