The researchers said the rise is much faster than even the most fossil-fuel intensive scenario developed by the Intergovernmental Panel on Climate Change (IPCC) during the 1990s.
The increase in emissions of the gases responsible for global warming suggests that the effects of climate change to come in this century could be even worse than United Nations scientists have predicted, the scientists said.
According to the study, this year's IPCC reports predicting reduced harvests, dwindling water supplies, melting glaciers and the loss of species may actually be understated.
Incidentally, the study comes soon after warnings by the International Energy Agency that China may overtake the US as the biggest emitter of greenhouse gases by 2010, a decade earlier than previously assumed.
Scientists from the Oak Ridge National Laboratory (US), the University of East Anglia and the British Antarctic Survey (both UK) as well as institutes in France and Australia wrote the study.
