A recent increase in a number of ozone-depleting chlorofluorocarbons (CFCs) poses a climate threat, scientists say. Five ozone-depleting chlorofluorocarbons significantly increased in the Earth ...

Chlorofluorocarbons (CFCs) are a class of synthetic chemicals used in a number of industrial applications, including refrigeration, air conditioning, and aerosols. First developed in the 1920s ...

Thirty years after countries agreed to ease up on the use of chemicals damaging the ozone layer, there are promising signs that the ozone will be fully recovered by the 2060s. But we’re not out ...

These chemicals create holes in the ozone layer and are powerful greenhouse gases. They’ve been banned since 2010, but pollution has kept growing. These chemicals create holes in the ozone layer ...

Emissions of the five chemicals–CFC-13, CFC-112a, CFC-113a, CFC-114a and CFC-115—equaled 47 million metric tons of carbon dioxide emissions in 2020 alone, according to the study.

The concentrations of some ozone-depleting chlorofluorocarbons (CFCs) in the atmosphere are increasing rapidly, scientists warn, despite the production of these chemicals having been banned ...

At the time, CFCs were commonly used in aerosol sprays and as coolants in many refrigerators. As they reach the stratosphere, the sun's UV rays break CFCs down into substances such as chlorine.

Testing simulations based on different climate factors, researchers seemingly confirmed that efforts to limit the emission of ...

Chlorofluorocarbons (CFCs), man-made gases once widely used in air conditioners and refrigerators, were banned in 2010 in a landmark international agreement called the Montreal Protocol.

Scientists determined the production of chlorofluorocarbons (CFCs), which were widely used in refrigeration, aerosols, solvents, and fire extinguishers caused the problem. When chlorine and ...
