This video is narrated by NASA scientist Peter Griffith who explains fast and slow carbon cycling on Earth. A banana is an example of fast, young carbon. A chunk of coal is an example of old, slow carbon. Carbon dioxide and vegetation on land seen... (View More) from space by satellites show the annual cycle: as plants grow during spring and summer they draw carbon dioxide out of the air during photosynthesis. When they die or go dormant during winter, carbon dioxide levels rise in the atmosphere. Burning fast or slow carbon to generate power or heat releases black carbon, also called soot which can be seen from space.

This video explains air quality and specifically describes Earth's air pollution seen from space by satellites. As the world's largest environmental health risk, air pollution is important to understand, monitor, and reduce. Over the past 10 years,... (View More) air pollution has reached epic levels in some places in the world, even as air quality has improved in other places.

This brief (1:46) video explains the stratospheric ozone layer and its role in absorbing harmful UV radiation from the sun. The visualization shows how the thickness of the ozone layer varies with air flow aloft and seasons, and where the biggest... (View More) changes occur.

This video features NASA scientist Claire Parkinson explaining atmospheric carbon dioxide levels seen in measurements collected at the Mauna Loa observatory since 1958 and recent global model output. The seasonal cycle of plants on land and in the... (View More) ocean explains the annual rise and fall of carbon dioxide. The long-term trend toward more CO2 in our atmosphere is largely due to human activity. We are putting CO2 into the air faster than nature can remove it. (View Less)
