This movie explains how climate scientists use "fuzzy" proxy records to learn about climates of the past.

This video explains how climate records from the past show that changes in temperature and changes in atmospheric carbon dioxide go hand-in-hand.

In the past century, as the climate has warmed, sea level rise has accelerated. Scientists predict it will only increase, and they're studying changes in the ocean and land to better understand how and why the water is rising.
