Thirty years ago, the nations of the world agreed to the landmark 'Montreal Protocol on Substances that Deplete the Ozone Layer.' The Protocol limited the release of ozone-depleting chlorofluorocarbons (CFCs) into the...

This video talks about the importance of the Ozone Mapper Profiler Suite (OMPS), flying on board NPP. OMPS is critical for measuring the health of the stratospheric ozone. <b<b<br/>r/>r/>

The next three decades will see an end of the era of big ozone holes. In a new study, scientists from NASA Goddard Space Flight Center say that the ozone hole will be consistently smaller than 8 million square miles by the year...

NASA and NOAA scientists work together to study the ozone layer, monitoring the hole over Antarctica as it fluctuates with the seasons.

This year, the ozone hole's annual maximum set a record -- the smallest it's been...

Where’s it coming from? With global average temperatures rising, it would be natural to assume that total quantities of sea ice would be falling. But it’s not. Scientists have begun to observe sea ice increases around Antarctica, and...

This short video combines dynamic ozone visualizations with an interview with leading atmospheric NASA scientist, Dr. Paul Newman. Dr. Newman explains why ozone is important, he cites the ingredients that cause an ozone hole to form,...

Every year, NASA and NOAA track the hole in the ozone layer over Antarctica as it grows to its annual winter maximum. This year, the hole was smaller than expected, due to an unusual weather pattern in the...

As the coronavirus pandemic slowed global commerce to a crawl in early 2020, emissions of nitrogen oxides (NOx) – which create ozone, a danger to human health and to climate – decreased 15% globally with local...

The hole in Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric...

NASA's Earth Polychromatic Imaging Camera (EPIC) sits onboard NOAA's Deep Space Climate Observatory (DSCOVR) satellite at the Lagrange point 1, a million miles away from Earth.



EPIC has been imaging the sunlit...

Need some organic chemistry practice? Here's a tricky synthesis to try!

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite has been scanning Earth for 20 years and now has a long enough record to help support climate change research. AIRS data on Earth’s atmosphere are...

Through animation and video footage students will learn that there are two basic types of catalysts, heterogeneous and homogeneous. Students will come to understand that catalysts have many practical applications and that scientists use...

Scientists are closely monitoring positive signs of recovery of the Earth’s stratospheric ozone layer, which is depleted by the use of chemicals called chlorofluorocarbons (CFCs) for a range of industrial and commercial purposes. Even...

Humanity is a clumsy species. How else can you explain all the times we've almost fumbled our way into extinction. From nuclear false alarms to poisoned crops, here are 10 Times The World Almost Ended By Accident.

Learn the basics about the changes to our atmosphere, as a part of environmental chemistry.



The Earth’s early atmosphere had no oxygen. By examining rocks laid down over earth history we can piece together the...

Learn some more about the hole in the ozone, as a part of environmental chemistry. The hole in the ozone layer has become thinner, mainly due to CFC’s. CFCs are inert stable molecules and were once the wonder chemical. They were...

Through animation and video footage students will learn that there are two basic types of catalysts, heterogeneous and homogeneous. Students will come to understand that catalysts have many practical applications and that scientists use...

In this video we will looks at what allotropes are, and different examples of them. The term allotrope refers to different forms of the same element. Diamond and graphite are made of only carbon atoms – yet they exhibit very different...

Learn the basics about the effect of air pollutants on health within environmental chemistry.

Through telescopic video and photos combined with animated graphics, students will learn about the layers of the sun and its effects on earth, the moon and all the objects in our solar system and the universe.

Real World Science : The Science of Climate Change

This program begins by explaining how scientists have learned that Earth’s climate has changed many times over billions of years and that Earth’s climate is...

Atmosphere Set: 1. This clip examines the chemical composition and the layers of the atmosphere.

The 3 simple ingredients of sun, air and water lead to every type of weather on Earth. The atmosphere is constantly trying to balance heat from the sun with water vapor and air to create a dynamic planet. The unique properties of the...
