There are things we know that we know, there are things that we know we don’t know, and there are four previously unknown ozone-eating gases that we now know are eating the ozone. (It goes something ...

The hole in Earth’s ozone layer — which made headlines in the 1970s and 1980s but which has been slowly healing since an international treaty banned the chemicals creating it — is growing bigger again ...

Two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been found in the atmosphere by a group of scientists. Scientists made the discovery by comparing today's air samples ...

Scientists at the University of East Anglia have identified four new human-made gases in the atmosphere -- all of which are contributing to the destruction of the ozone layer. New research reveals ...

UNSOLVED MOSTLY SOLVED MYSTERY. Last month, scientists published a report detailing a recent increase in emissions from chlorofluorocarbons (CFCs), an industrial gas banned since 2010. The New York ...

Synthetic gases developed as a "safer" replacement for chlorofluorocarbons which caused the hole in our planet's ozone layer above Antarctica can still represent a risk, MIT scientists say. When ...

Scientists at the University of East Anglia have found two new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) in the atmosphere. The research, published today in the journal ...

In 1974, scientists discovered that humans were unintentionally causing ozone depletion — a potential climate disaster. In 1985, when they discovered the Antarctic ozone hole and realized how severe ...

One of the earliest climate model predictions of how human-made climate change would affect our planet showed that the Arctic would warm about two to three times more than the global average. Forty ...

All major analyses of annual average temperatures in the northern hemisphere observe that temperatures were relatively constant from 1945 to 1969, rose one degree Fahrenheit from 1969 to 1998, ...

OSLO (Reuters) – Scientists have detected four new man-made gases that damage the Earth’s protective ozone layer, despite bans on almost all production of similar gases under a 1987 treaty, a study ...

While most of the focus in developing a policy to fight global warming has been on carbon dioxide, other gases also contribute to climate change. The effect of these gases is still poorly understood ...
