People are becoming more aware of the health risks of laughing gas, but fewer people realise it’s a potent greenhouse gas.

The UK space launch failed but it succeeded in releasing hazardous pollutants to multiple layers of the atmosphere.
It’s the World Health Organization’s first update of global air quality guidelines since 2005. We know far more today about the serious risks these pollutants pose to human health.
Depending on who you ask, the northern lights may, very occasionally, sound like ‘rustling silk’ or ‘two planks meeting flat ways’.
Ozone pollution is on the rise, and it’s getting into people’s homes.
Here’s what a space tourism industry led by Bezos, Branson and Musk might mean for the planet.
Exaggerating how much lockdown improved air quality could allow us to underestimate the scale of the air pollution problem.
New research on the Late Devonian extinction suggests the ozone layer could be naturally depleted as the temperature rises.
New research finds that chlorofluorocarbons (CFCs) and other ozone-depleting substances have boosted the effects of climate change in the Arctic.
Measurements and modelling have found nitrous oxide emissions, a greenhouse gas 265 times more potent than carbon dioxide, are significantly higher than previously reported.
Air quality in the US has improved greatly since 1990, but a new report finds progress stalling in some cities. Meanwhile, the Trump administration is rolling back air pollution controls.
The number of substances emitted into the atmosphere is immense and growing, but some are particularly harmful to health and are subject to increased monitoring.
An air pollution expert with years of experience advising federal regulators describes how the Trump administration is speeding up reviews and reducing scientific input.
A study of the social cost of carbon emitted by the shrinking fleet of Texan coal plants suggests that closing more of them down would be good for the climate and public health.
US ozone pollution has fallen in recent decades, but exposure to low levels of ozone still has serious effects on human health and well-being.
Almost 30 years ago the world responded to the realisation that our ozone layer was in trouble. The resulting Montreal Protocol was a rare example of global cooperation, but there’s no room for complacency.
US national parks protect some of America’s most spectacular outdoor settings. But new research shows that ozone pollution levels in the parks are roughly as bad as in major cities.
EPA Administrator Scott Pruitt wants to change the grounds for setting US air pollution targets. An environmental lawyer explains why Pruitt’s approach misreads the law and could roll back decades of gains.
New research is spotlighting personal care products, such as shampoos and skin lotions, as a significant source of chemicals that contribute to urban air pollution.
Earth’s ozone layer shields us from harmful ultraviolet radiation. Nations have been working to reduce ozone-depleting chemicals since the 1980s, but recent studies show that there is still work to do.
