A new study has found that there is a 95 per cent chance that human activity is to blame for global warming, and only 5 percent chance that the climate change is due to natural factors.

According to a report in the Times, the study was carried out by senior scientists from the Met Office Hadley Centre, Edinburgh University, Melbourne University and Victoria University in Canada.

The "fingerprints" of human influence on the climate can be detected not only in rising temperatures but also in the saltiness of the oceans, rising humidity, changes in rainfall and the shrinking of Arctic Sea ice at the rate of 600,000 sq km a decade.

There was a less than 5 per cent likelihood that natural variations in climate were responsible for the changes.

The study said that the Intergovernmental Panel on Climate Change (IPCC) had understated mankind's overall contribution to climate change.

The IPCC had said in 2007 that there was no evidence of warming in the Antarctic.

However, the panel said that the latest observations showed that man-made emissions were having an impact on even the remotest continent.
