Ozone

  • The Montreal Protocol in the 1980s has allowed the ozone layer to recover, and now scientists have found that it had another benefit – it’s already slowed climate change effects by up to 25 percent, giving hope we could meet the ongoing challenge.
  • Science
    New research has found that each of us is regularly producing our own personal cloud of pollutants, affecting indoor air quality. But not the way you think. The team found that oils on our skin and clothes are reacting with ozone in the air, producing a range of volatile and semi-volatile substances
  • The hole in the ozone layer may be on the mend, but its environmental impacts are ongoing. A new review study has examined the effects that the extra UV radiation is having on the environment, such as shifting climate zones, changing ocean temperatures and making some species more vulnerable.
  • ​​Around 30 years ago, the world came together to mend a widening hole in the Earth’s ozone layer, which plays a very important role in shielding us from ultraviolet rays. A new report has revealed that this long-term healing strategy is continuing to pay dividends.
  • ​Back in 1987, the global community signed an agreement known as The Montreal Protocol, which called for all countries to phase out the production of ozone-layer-depleting chlorofluorocarbons (CFCs). According to a new study, however, one of the most abundant CFCs is likely still being made.
  • A new study has revealed that ozone levels in the heavily populated lower latitudes don't seem to be recovering as well as regions near the poles. Although there isn't yet a clear explanation as to why this is happening, blame may still rest on short-lived ozone-destroying chemicals.
  • It’s long been known that the hole in the ozone layer is shrinking, but a new study has provided greater insight into the improving health of the ozone layer by analyzing the chemicals around the hole over the last decade or so.
  • ​According to a new study, evidence of alien life in the atmospheres of potentially habitable exoplanets could be hidden from telescopic eyes by unusual air flow patterns. The research could have significant implications regarding how astronomers carry out their search for extraterrestrial life.
  • ​It is expected to prevent 280 million cases of skin cancer in the US alone. Without it, the sun would burn skin in minutes. Yet the strides made by the Montreal Protocol in repairing our ozone layer may be undone thanks to dangerous chemicals now making their way into the upper atmosphere.
  • As many cities around the world become greener with plant-clad towers, vertical gardens and tree-filled urban developments, ​​a recent study has revealed that during heat waves, trees in a city can actually contribute to higher levels of air pollution.
  • The Roving Blue O-Pen supports world travellers and nomads by keeping drinking water clean and fresh. In contrast to more common purification means, like UV rays, this pen-sized purification device kills microorganisms with the stuff that blocks those UV rays in the atmosphere: ozone.
  • In the 1980s, pretty much every country in the world agreed to ban the use of CFCs, a decision that is now paying big dividends with scientists reporting significant shrinkage of the hole in the ozone layer and evidence of what looks to be a path to recovery.
