Lesson 13

Projections of Future Changes in Climate

Climate science is based on the assumption that Earth's climate system is understandable and predictable. Observations, experiments, and theory used to construct and refine computer models and develop scientific explanations have led to a much better understanding of the links between the atmosphere-ocean system and how it relates to the overall climate system's behavior. As a result, increasingly more reliable projections of future climate have developed over time. Based on computer models and observations, scientists know that Earth will continue to warm and sea levels will rise due to the greenhouse gases we have already pumped into the atmosphere.

In this lesson you will learn:
1) Temperature & precipitation projections during the 21st century
2) Projections for climate change across several environmental systems
