The ultraviolet index measures the intensity of the sun's harmful rays. Learning how to read it can help you protect your ...

For decades, the Earth’s ozone layer, which protects life on our planet from the sun’s harmful ultraviolet (UV) rays, has taken a beating from common chemicals used in everything from ...

The good news is that the ozone layer is recovering. In the winter months of 2005 and 2016, scientists saw a 20 percent decrease in ozone thinning—the first evidence that it was recovering.

The ozone layer shields the earth from the sun’s ultraviolet rays. But a recent report concluded that this layer is thinning rapidly due to trace gases. Primarily, CFCs in consumer products.

Ozone levels: The ozone layer helps block UV rays, so thin ozone means higher UV. Cloud cover: Some clouds can block UV rays, but thin or scattered clouds don’t do much.

In this article, we’ll take a closer look at the key differences between UVA and UVB rays, how they affect your skin, and what you can do to limit sun damage.

There have been lots of letters lately about global warming. How about some information about Ozone Depletion, causing an increase of UV cancer causing rays in our environment? I think this may be ...

The ozone layer shields life on Earth. We’ll soon lose a key way to monitor its health. NASA's Aura and Canada's SCISAT near the end of missions to monitor ozone-depleting substances ...

In 2015, scientists at NASA predicted that the Ozone Hole would be half closed by 2020. That hasn’t happened. Other scientists have forecasted that the hole will not begin to disappear until 2040 or ...

A scientist recently claimed that he'd discovered a gargantuan hole in the ozone layer that first appeared above the tropics in the 1980s but went unacknowledged until now. However, upon his ...

The hole in the ozone layer that surrounds the Earth's atmosphere reached the 12th-largest single-day size on record on Sept. 21, 2023, despite improving overall, according to the NOAA.

On 16 September, the world will mark the International Day for the Preservation of the Ozone Layer. It was on this day, 35 years ago, that the Montreal Protocol was adopted. Let’s look at how ...
