Potent Greenhouse Gas Produced by Industry Could Be Readily Abated With Existing Technologies

Researchers have found that one method of reducing greenhouse gas emissions is available, affordable, and capable of being implemented right now. Nitrous oxide, a potent greenhouse gas and ozone-depleting substance, could be readily abated with ...

Study of Earth's Stratosphere Reduces Uncertainty in Future Climate Change

New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the ...

New evidence from Antarctica shows that toxic 'fluorinated forever chemicals' have increased markedly in the remote environment in recent decades and scientists believe CFC-replacements ...

Ozone Depletion Over North Pole Produces Weather Anomalies

Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than ...

Research Reveals Why Tackling Particle Pollution Leads to Rise in Photochemical Smog

Researchers have discovered why reducing particle pollution is leading to a rise in photochemical smog in some emerging economies such as India, Africa and ...

Discovery Reveals Large, Year-Round Ozone Hole Over Tropics

Scientist reveal a large, all-season ozone hole in the lower stratosphere over the tropics comparable in depth to that of the well-known springtime Antarctic hole, but roughly seven times greater in ...


Climate Damage Caused by Growing Space Tourism Needs Urgent Mitigation

A formidable space tourism industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new ...

Lesser Known Ozone Layer's Outsized Role in Planet Warming

New research has identified a lesser-known form of ozone playing a big role in heating the Southern Ocean -- one of Earth's main cooling ...

Ozone May Be Heating the Planet More Than We Realize

New research reveals ozone in the lower atmosphere in particular contributed to warming in the Southern Ocean - which absorbs much of the planet's excess heat - more than previously realized. ...

Smoke from Major Wildfires Destroys the Ozone Layer

A new study shows that smoke from wildfires destroys the ozone layer. Researchers caution that if major fires become more frequent with a changing climate, more damaging ultraviolet radiation from ...

Chemical Link Between Wildfire Smoke and Ozone Depletion
