A new healing gel helped mice regrow brain tissue after a stroke, and scientists suspect someone out there is producing a bunch of ozone-destroying CFCs in defiance of an international agreement! Hosted by: Hank Green

Lots of global problems seem intractable, but there’s a formula for success that we can follow.

Sally Le Page joins us on Quiz Show this week, where we celebrate the submission of her doctoral thesis with the most peaceful, relaxing questions we could devise, assuming you don’t count the volcanoes or screamed-at caterpillars

A new healing gel helped mice regrow brain tissue after a stroke, and scientists suspect someone out there is producing a bunch of ozone-destroying CFCs in defiance of an international agreement!

In this video Paul Andersen explains how stratospheric ozone protects humans from ultraviolet light. He explains how stratospheric ozone is formed when diatomic oxygen absorbs an ultraviolet photon and is split into two free oxygen...

The technology we use to keep cool is heating the world in a vicious feedback cycle, so we need to improve it and use it less.

In this video Paul Andersen explains how the atmosphere surrounds the planet. The state of the atmosphere is climate and is affected by unequal heating, the Coriolis Effect, and the ocean. Convection cells and ENSO are discussed in...

Esta película examina los indicios de contaminación del aire y cómo sus efectos pueden ser catastróficos para los ecosistemas.

“The Ozone Layer” will explain what the ozone layer is, how it is being damaged, and how global warming and climate change interact with it.

The ozone layer’s recovery is stopping changes in the atmospheric circulation systems of the Southern Hemisphere, according to new research. <br<br/>/>

An aerosol is a mist of liquid particles. Aerosol sprays are used in a variety of products from spray paint to sunscreen. Learn how the aerosol system works and about some potential dangers of aerosol spray.

Pushed by warming air and pulled by a shrinking stratosphere, no one knows where the troposphere goes from here.

According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable...

A colder than usual winter in the southern hemisphere fed a deep and larger than average hole that persisted for a longer period than usual.

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,...

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...

/ story on the sun damage caused by the disintegration of the ozone layer in the atmosphere / sunbathers on beach, suntanning / Dr Darrel Rigel speaking to Congress about damaging effects from Ozone depletion and the increase in skin...

Extrapolated simulation 1974 to 2065 of what would have happened to global concentrations of stratospheric ozone if chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals were not banned through the Montreal Protocol

Dr Donald Heath from NASA's Goddard Space Flight Center and Dr Robert Watson from NASA testify before Congress about the dangers of the depletion of the earth's ozone atmosphere layer. Discovery of hole in the ozone layer prompts congr...

In the first installment of "Operation: Earth," Newsy's "In The Loop" dives into the ozone solution and its relation to climate change issues.
