U.S. states need to put in place new ozone air quality standards, but how they are measured – based on peak ozone – doesn’t always best reflect a city’s overall air quality.
Mexico City is suffering through an air quality crisis this spring, but institutional corruption is making the proposed solution – restricting car usage – ineffective.
The Paris climate summit yielded a pact to reduce air pollutants that contribute to global warming but missed a chance to address the interlinked effects of agriculture and climate.
The greenhouse gases that cause climate change will take centre stage at the upcoming Paris climate talks. What are they and what are their effects?
Conflicting evidence means it’s tough to tell whether trees helping to clear the air, or if green is not as good as we thought.
The US has stricter ozone rules but the limits lag guidelines set by some other countries and more coordination in regulation is needed to address air pollution globally.
Outdoor air pollution causes 3.3 million premature deaths a year, mainly in Asia. And without policies to cut particulate pollution from traffic, industry and home biofuels, the deaths could double by 2050.
Many people think of sunburn and skin cancer when they hear about the ozone hole. But more ultraviolet (UV) radiation isn’t the only problem. The ozone hole has also led to dramatic changes in Southern…
Over 2012 and 2013, parts of New Zealand experienced their worst drought in nearly 70 years. Drought is the costliest climate extreme in New Zealand; the 2012-2013 event depressed the country’s GDP by…
It sometimes feels as if environmental news is never good news, but that certainly isn’t true when it comes to the ozone layer. The UN has announced that the ozone layer is showing “signs of recovery…
So serious are the effects of air pollution on human health - the WHO recently categorised it as carcinogenic, responsible for 223,000 deaths a year worldwide - that it is easy to neglect its wider impact…
Flights entering and exiting Australia and New Zealand are responsible for the highest levels of ozone pollution created…
Much research is being done in the Arctic to find out what changes there will mean for the rest of the world. One scientific…
Increases in ground-level ozone make it hard for insects to interact with the plants they rely on. Insects rely on olfactory…
