The first study found that the hole in the ozone layer, caused by the use of CFCs, has prevented the melting of Antarctica even as the rest of the world warms. A separate study found that plants absorb more carbon dioxide under polluted skies, therefore slowing global warming. Scientists said the findings made it even… [Read more…]

The evils of global warming and ozone depletion are competing problems, at least in Antarctica, the results of two new studies suggest. Schemes to pump sulfur into the atmosphere to counteract global warming might help cool the Earth, but they could also cause problems at the poles, scientists warned today. Continuous injections could drastically deplete… [Read more…]

Scientists believe that Global Warming will lead to a weaker Ozone layer, because as the surface temperature rises, the stratosphere (the Ozone layer being found in the upper part) will get colder, making the natural repairing of the Ozone slower. NASA, for example, reports that by 2030, “climate change may surpass chlorofluorocarbons (CFCs) as the… [Read more…]
