The Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) has concluded that several freak weather incidents in Europe, India, Pakistan and Nepal over the last 50 years are attributable to human activities and emissions of carbon di-oxide due to fossil fuel burning are virtually certain to be dominant influence on the trends during the 21st century.

Addressing a press conference here on Friday, IPCC chairman RK Pachauri said: The heat waves that swept across the world triggering fires in Europe while sweeping flash floods have occurred in India, Pakistan and Nepal resulted beacuse of climate changes and would impact the developing countries, thereby exacerbate inequities in health status and access to adequate food, clean water and other resources.
