There are significant gaps in what teachers in Ghana know about ozone depletion and climate change, even though these subjects are in the science curriculum.
When solar particles reach the Earth, they not only produce spectacular auroras but also contribute to the chemical reactions leading to ozone depletion, which in turn influences climate patterns.
For several years, emissions of CFCs have been rising, in apparent defiance of a global ban in place since 2010. A new global detective effort has traced the source to two eastern Chinese provinces.
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.
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…
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…
On Monday, a report appeared in the Australian claiming a link between chlorofluorocarbons (CFC) in the atmosphere and global warming. The report claimed “banned aerosols” and not carbon dioxide were “responsible…
