HFCs keep refrigerators cool, but their leaks are warming the planet.

HFCs keep refrigerators cool, but when these short-lived climate pollutants leak, they warm the planet. The US EPA has a plan to phase them out, but what will replace them?
Earth’s magnetic field protects us from the solar wind, guiding the solar particles to the polar regions.

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.

Scientists have uncovered evidence of a global paleopocalyspe.

Artificially dimming the sun, by injecting reflective particles into the upper atmosphere, could reduce the risk of Day Zero level droughts in Cape Town by more than 90% in the future.

Molina, who died on Oct. 8, 'thought climate change was the biggest problem in the world long before most people did.' His research on man-made depletion of the ozone layer won the 1995 Nobel Prize.
New research on the Late Devonian extinction suggests the ozone layer could be naturally depleted as the temperature rises.
Temperatures are warming faster in the Arctic than anywhere else in the world. Water and sewer pipes in Iqaluit, Nunavut, are cracking during the winter as the ground shifts.

New research finds that chlorofluorocarbons (CFCs) and other ozone-depleting substances have boosted the effects of climate change in the Arctic.
Lush moss beds in East Antarctica’s Windmill Islands.
Mosses are the only plants that can withstand life in East Antarctica's frozen landscape. But a new study shows that life is getting even harder, as ozone loss and climate change make conditions even drier.
Researchers release a balloon carrying instruments to measure ozone levels above Antarctica.
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.
Suspected infestation of Macrophomina phaseolina, a “novel” soil pathogen, in the non-fumigated buffer zone of a strawberry field.
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?
Sunrise over the Earth. Hydrofluorocarbons were created to protect the ozone layer, but their stable nature makes them an extremely potent greenhouse gas.
Australia has ratified an agreement to phase out hydrofluorocarbons, a manmade compound once hailed as the saviour of the ozone layer. What went wrong?
Clouds over Australia’s Davis Research Station, containing ice particles that activate ozone-depleting chemicals, triggering the annual ozone hole.
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.
You can only truly understand the weather by flying above the clouds.
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.
The Montreal Protocol has successfully reduced the use of chemicals that destroy the Earth’s ozone layer.

Hydrofluorocarbons were created to replace ozone-damaging chemicals – but they turned out to be major contributors to climate change.
Ban on CFCs in aerosol sprays and refrigerants has led to a steady shrinking of the ozone hole.
What the Montreal Protocol has done for the ozone hole threat other international accords could do for climate change – if we all agree.
These clouds – formed high in the Antarctic atmosphere during spring – provide a place where ozone-destroying chemicals can form.
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…
Antarctica has actually been protected from sea ice melt by the ozone hole.
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…
In 2012 and 2013 parts of New Zealand suffered the worst drought in 70 years.
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…
Ozone conditions as of September 7, 2014.
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…
