Scientists question global warming

While the Intergovernmental Panel on Climate Change made its conclusion on the cause of global warming, some scientists have cast doubt on the report.

Earlier, more than a thousand e-mails sent between some of the world's top climate specialists have been exposed by hackers, drawing questions about the seriousness of global warming.

Scientists casting doubt on global warming have taken their plea to Copenhagen where they are holding a rival conference. This follows the discovery of e-mails written by climate specialists accusing them of colluding to suppress others' data and enhance their own.

Increased carbon dioxide does not cause global warming according to these climate change sceptics.

Ian Plimer, Professor of Mining Geology, Adelaide University, said, "Pollution kills us and carbon dioxide is not a pollutant. It makes plants grow. And without carbon dioxide, we don't eat."

However, others argue that reducing carbon emissions is still a necessity.
