The National Research Council is pleased to present this booklet in 3 parts that (1) summarizes the current state of knowledge about climate change; (2) explains some impacts expected in this century and beyond; and (3) examines how science can help inform choices about managing and reducing the risks posed by climate change.

Video: Climate Change: Lines of Evidence

This video, based on the first part of the booklet, further explores common questions about the science of climate change.

The video is also available in seven individual chapters, each focusing on a section of the booklet:

• Chapter 1: What is Climate?
• Chapter 2: Is Earth Warming?
• Chapter 3: Greenhouse Gases
• Chapter 4: Increased Emissions
• Chapter 5: How Much Warming?

You'll also find all seven videos together in a YouTube playlist here.
