California produces 90 percent of the US strawberry crop, but growers face curbs on toxic chemicals that have helped their industry expand. Can a system centered on mass production become more sustainable?
Australia has ratified an agreement to phase out hydrofluorocarbons, a manmade compound once hailed as the saviour of the ozone layer. What went wrong?
The treaty to limit the destruction of the ozone layer is hailed as the most successful environmental agreement of all time. Three decades on, the ozone layer is slowly but surely returning to health.
Far from being “politicised science”, as a Trump advisor has claimed, NASA’s satellite monitoring has been a crucial help in understanding the planet we live on.
Imagine an environmental crisis caused by a colourless, odourless gas, in minute concentrations, building up in the atmosphere. There is no expert consensus, but in the face of considerable uncertainty…
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…
Strong winds linked to climate change and the hole in the ozone layer are driving a steady increase in Antarctic sea ice, even as Arctic levels continue to shrink dramatically, a new report shows. While…
Scientists at the University of East Anglia have discovered new man-made gases that are contributing to the depletion of the Earth’s ozone layer. Three new Chlorofluorocarbons (CFCs), which act to destroy…
It’s been nearly 30 years since the discovery of the ozone hole over Antarctica, and the realisation that chlorine, in the form of chlorofluorocarbons or CFCs, was the chemical culprit behind the depletion…
