Study shows how daily habits like showering and changing clothes impact airborne chemical formation, surprising findings ...

When a satellite disintegrates in the upper atmosphere, it does not just disappear. Rather, it deposits a record of aluminum ...

Ozone pollution isn’t just a summer story anymore. In parts of northern China, high ozone levels are now appearing during ...

Ozone is a molecule comprised of three oxygen atoms that occurs naturally in small amounts. In the stratosphere, roughly seven to 25 miles above Earth's surface, the ozone layer acts like ...

While it can be difficult to vouch for ozone’s efficacy in medical settings, Joe Schwarcz can vouch for its power against skunk odour. JOHN MASSEY Postmedia files The Smelly Car is a classic ...

In sufficient concentrations, aluminum oxide easily catalyzes ozone’s destructive reaction with chlorine gas, which splits the ozone molecule and diminishes Earth’s UV shield.

Mr. Ferreira calculated that upon satellite re-entry, the bulk of a burned-up satellite could become aluminum oxide, a pollutant that could interfere with stratospheric ozone chemistry.

A team of Drexel University engineering students are traveling to Texas this week to launch a high-altitude balloon during the October 14 solar eclipse. Their goal is to study the rapid changes in ...

In this image, from September 2006, the Antarctic ozone hole was equal to the record single-day largest area of 11.4 million square miles (29.5 million square kilometres), reached on Sept. 9, 2000.

But, the researchers found, wildfire smoke broke down HCl in the lower stratosphere, generating a chemical called chlorine monoxide—“the ultimate ozone-depleting molecule,” per an MIT statement.

Towering clouds of smoke sent into the stratosphere by ferocious wildfires can eat away at Earth’s ozone layer thanks to a potent mix of smoke, atmospheric chemistry and ultraviolet light, a new ...

Few layers of Earth's stratosphere are as important to humans — or as endangered — as the ozone layer, so-named because of its disproportionately high concentration of the molecule ozone (O 3).
