After two decades of attempts, the Environmental Protection Agency (EPA) has finally started to annihilate the environmental threats posed by our own refrigerators.
It has succeeded in adopting a new regulation making eco-friendly refrigeration gases legal in the US, meant to replace the traditional option represen... |

Despite the fact that the production of chlorofluorocarbons has been forbidden for decades via an international agreement, the chemicals continue to damage Earth's ozone layer. This was made apparent again this year, as the Antarctic ozone layer hole reached its maximum annual extent.
The hole becomes most vis... |

Atmospheric scientists have recently determined that the hole in the ozone layer above Antarctica grew as big as it ever were this August, prompting speculations as to what may be the cause. Early data indicate that the chemicals responsible for the phenomenon take a long time to dissipate.
The world has largely ... |

The thinning of the ozone layer above the North Pole – which researchers began monitoring a few years back – is currently about to establish a new record. According to scientists, the layer has diminished significantly from its normal levels, and the trend appears to continue unabated. Generally, the thin... |

Over the past few years, scientists have been saying that the ozone layer above Antarctica is getting smaller. That may be so, but the feature still appears, grows, and then disappears yearly.Now, experts at NASA analyze the beginnings of this year's hole, which is the popular name given to the annual depletion ... |

Antarctica is host to a very powerful observatory, a neutrino telescope buried deep under its ices. The instrument's main function is to detect the elusive elementary particles, but experts found that it could also provide them with an in-depth look at the temperature variations taking place in the ozone layer, ... |

The world seems to have woken up just in time, researcher say, when more than two decades ago the United Nations and several leading countries in the world became aware of the first-ever sign of human activity influence on the atmosphere – the hole in the ozone layer. Despite the fact that it took 9 years to ge... |

The deadly gas is formed when sunlight hits various gases in the atmosphere, usually generated by human activities. The ever-increasing levels of pollution in major cities cause for larger quantities of ozone to be generated all the time. While the ozone layer in the upper atmosphere protects our planet against UV li... |

This year, the European Space Agency's (ESA) satellites and follow-up instruments recorded the second largest recorded hole in the ozone layer, second in size only to the one observed in 2006. While 2007 showed some promise in this regard, with an increase in the thickness of the layer, the tendency did not go o... |
