NOAA scientists forecast that the Gulf dead zone would measure roughly 6,700 square miles—bigger than the long-term average recorded since 1985, but lower than the record-high extent observed in 2017.

The Amazon Rainforest is a living warehouse for carbon dioxide. As climate changes, the lush tropical ecosystems of the Amazon Basin may release more carbon dioxide into the atmosphere than they absorb. NOAA scientist John Miller talks about how climate conditions in 2010 and 2011 created a natural experiment on how drought affects the Amazon's carbon balance.

Two simple experiments/demonstrations show the role of plants in mitigating the acidification caused when CO2 is dissolved in water.

This activity describes the flow of carbon in the environment and focuses on how much carbon is stored in trees. It goes on to have students analyze data and make calculations about the amount of carbon stored in a set of trees at three sites in a wooded area that were to be cut down to build a college dormitory.

This is an interactive visualization of the Carbon Cycle, through short-term and long-term processes.

In this activity, students use a physical model to learn the basics of photosynthesis and respiration within the carbon cycle.
