| The Data A Paleo Perspective on Global Warming is divided into two sections: The Story and The Data. The goal of The Data is to offer a comprehensive look at the instrumental and paleoclimatic data that tells us how the Earth's temperature has changed over the past years to the millennia. Within this section there are three chapters:
Due to many more paleoclimate records becoming available throughout the world, scientists have a more improved view of past changes in the Earth's temperature then we had ten years ago. This chapter focuses on five recent studies that have revolutionized what we know about the 20th century in the context of the last six centuries.
Just as the previous chapter puts the 20th century in the perspective of the last 1000 years, this chapter looks further back into Earth's history to see if previous periods of global warmth can provide clues about 20th century warming.
