Study shows green roofs could reduce indoor air pollution

Green roofs – roofs that are planted with vegetation—may improve the indoor air quality of commercial buildings by cutting the amount of ozone coming into the buildings from the outside, according to new research from Portland State University.

Study finds rising ozone a hidden threat to corn

Like atmospheric methane and carbon dioxide, ground-level ozone is on the rise. But ozone, a noxious chemical byproduct of fossil fuel combustion, has received relatively little attention as a potential threat to corn agriculture.

Sources of new ozone-damaging HCFCs traced back to origins

An international team of researchers has located the source of recently discovered ozone damaging HCFCs in the atmosphere. In their paper published in Proceedings of the National Academy of Sciences, the group describes using new tools in addition to those used by members of the Montreal Protoco ...

Scientists solve air quality puzzle: Why does ozone linger long after its ban?

When high in the atmosphere, ozone protects Earth from harmful solar radiation—but ozone at ground level is a significant pollutant. Exposure to high concentrations of ground-level ozone aggravates respiratory illnesses, thus exacerbating the negative health effects of heat and contributing to t ...

Ozone: The Earth's protective shield is repairing

The ozone layer, which protects us from ultraviolet light, looks to be successfully healing after gaping holes were discovered in the 1980s. The Northern Hemisphere could be fully fixed by the 2030s and Antarctica by the 2060s.

Ozone pollution in Germany falls thanks to lower nitrogen oxide emissions

Summer is the ozone season: The harmful gas forms at ground level on hot, sunny days. In recent years, however, the rise in ozone levels over the summer months has not been as pronounced in Germany as it was previously. According to a new study, this is primarily due to a reduction in nitrogen o ...

Ozone may be heating the planet more than we realize

Ozone may be weakening one of the Earth's most important cooling mechanisms, making it a more significant greenhouse gas than previously thought, research has found.

Ozone Layer Is Recovering, Thanks To Climate Change Treaty Signed Over 30 Years Ago, Finds Study

Earth’s ozone layer, responsible for protecting the planet from Sun’s ultraviolet rays, has been healing and might even fully recover, a recent study has revealed. The study, published in the science journal Nature, said that the recovering ozone hole might have been a result of the 1987 Montrea ...

New method to investigate the impact of climate change on ozone levels

The oxygen in the air that we breathe is O2. Two oxygen atoms joined together to form a diatomic molecule. It is essential to life. However, there is another form of oxygen where three oxygen atoms join together to make an O3 molecule. We call this triatomic oxygen, ozone.

Largest hole in ozone layer above Arctic closes: How it happened and what it means

The polar vortex led to the concentration of excessive ozone-depleting substances that combined with the extreme cold leading to the creation of this large hole in the Ozone layer over the North Pole.

How the US Clean Air Act saved 1.5 billion birds in 50 years

The improved air quality and reduced ozone pollution that followed the 1970 passage of the US Clean Air Act and later amendments have saved the lives of 1.5 billion birds across the continent, according to new research.

How severe drought influences ozone pollution

From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation. Drought conditions can have complicated effects on ozone air quality, so to better understand the process, researchers have analyzed data from two ozone- ...

Four in 10 Americans live in counties with unhealthy air pollution levels

New research from the American Lung Association find that more than four in 10 people – a whopping 135 million in the US – live in counties with unhealthy levels of particle or ozone pollution.

Fixing the environment: when solutions become problems

In a world where climate change, air and water pollution, biodiversity loss, water scarcity, ozone depletion, and other environmental problems overlap, a fix in one arena can cause trouble in another.

Examining the intricacies of ozone removal by deciduous forests

Ozone plays a vital role in Earth's climate system. In the stratosphere, which begins about six miles (9.7 kilometers) off the ground, ozone protects the planet from harmful ultraviolet radiation. Lower in the atmosphere, however, the molecule is an air pollutant injurious to both humans and pla ...
