Climate change 'unequivocal,' scientists say in Paris report

International scientists and officials hailed a report toay saying that global warming is 'very likely' caused by man, and that hotter temperatures and rises in sea level 'would continue for centuries' no matter how much humans control their pollution.

The head of the Intergovernmental Panel on Climate Change, Rajendra Pachauri, called it a 'very impressive document that goes several steps beyond previous research.'

A top U.S. government scientist, Susan Solomon, said 'there can be no question that the increase in greenhouse gases are dominated by human activities.'

The 21-page summary of the panel's findings released today represents the most authoritative science on global warming, which the experts describe as an 'unequivocal' problem.
