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.
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.
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 Montreal Protocol is finally closing the hole in the ozone layer.
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.
Hydrofluorocarbons were created to replace ozone-damaging chemicals – but they turned out to be major contributors to climate change.
What the Montreal Protocol has done for the ozone hole threat other international accords could do for climate change – if we all agree.
Much has been made of the domestic political roadblocks between US President Barack Obama and climate action. But by using existing treaties he can get around the hostile Congress and help cut global emissions.
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…
