These compounds, known as chlorofluorocarbons (CFCs), could float up into the stratosphere and break down a protective layer of ozone, allowing more ultraviolet light to enter the atmosphere and ...

Located in the stratosphere, the ozone layer blocks potentially harmful ultraviolet energy from reaching our planet's surface.

What’s more, scientists will lose their ability to watch for harmful impacts to the ozone layer from wildfires and stratospheric aerosol injections aimed at countering climate warming.

However, global efforts to reduce halocarbon use have since led to a slow but steady recovery of the stratospheric ozone layer. About 90% of Earth's ozone is in the stratosphere, where it protects ...

destroying the ozone layer. One atom of chlorine in the stratosphere can destroy more than 100,000 ozone molecules, the EPA states. The ozone layer provides critical protection to Earth from ...

In the 1980s, scientists found that chlorofluorocarbons used in aerosol cans and refrigerators were destroying stratospheric ...

Earth's ozone layer is vital to protecting all forms of life – from crops to humans – from the sun's harmful radiation. This shield in Earth's stratosphere has been depleted for decades ...

Over the past 30 years, humans have successfully phased out many of the chemicals that harm the ozone layer, the atmospheric shield that sits in the stratosphere about nine to 18 miles (15 to 30 ...

"This important milestone demonstrates the benefits of the Protocol for mitigating climate change and stratospheric ozone layer loss." Ultimately ratified by 198 nations, including every country ...

It is expected to recover to 1980 levels by 2040, a new U.N. report found. When the hole in the ozone layer was first discovered in 1985, Paul A. Newman was shaken as a scientist. "I lost a lot of ...

Located in the stratosphere, the ozone layer acts like sunscreen, blocking potentially harmful ultraviolet energy from reaching our planet's surface. Without it, humans and animals could ...
