This video, video transcript, and accompanying poster, go beyond a description of weather and climate to highlight how NASA tracks the changes in climate and why it matters. Students will leave the video with the important sense of why data (in this case, gathered by satellites) is helping all of us monitor sea level, clouds, and to know that the earth's climate is getting warmer.

This is the first of three short videos showcasing the dramatic changes in Alaska's marine ecosystems. This introduction to the impacts of climate change in Alaska includes interviews with Alaska Natives, commentary by scientists, and footage from Alaska's Arctic.
