Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.

Human activities, mainly burning fossil fuels, are increasing the amount of carbon dioxide in our atmosphere, amplifying the natural greenhouse effect and making the pH of the ocean more acidic.

NOAA's Susan Solomon was awarded the 2009 Volvo Environment Prize for her pioneering contributions in atmospheric chemistry and physics.

In this activity, students explore factors that have caused the rise in global temperature over the last century. Educators have the opportunity to assess how modeling activities (the game), analogies (the cake), and mathematical models (graphs) develop and change student mental models.

In this short video, atmospheric scientist Scott Denning gives a candid and entertaining explanation of how greenhouse gases in Earth's atmosphere warm our planet.

Two short, narrated animations about carbon dioxide and Earth's temperature are presented on this webpage. The first animation shows the rise in atmospheric CO2 levels, human carbon emissions, and global temperature rise of the past 1,000 years; the second shows changes in the level of CO2 from 800,000 years ago to the present.

This short animated video provides a general overview of the atmosphere, carbon dioxide, and the greenhouse effect.

In this short video from ClimateCentral, host Jessica Harrop explains what evidence scientists have for claiming that recent global warming is caused by humans and is not just part of a natural cycle.
