London: Scientists have revealed that a `hiatus` in global warming- partly caused by natural climate variations this century - is not likely to last.
According to a draft of the Intergovernmental Panel on Climate Change (IPCC) report, factors including a haze of volcanic ash and a cyclical dip in energy emitted from the Sun may also have contributed to slower warming trends, the Independent reported.
The temperatures have risen more slowly in the past 15 years despite rising emissions of greenhouse gases.
This fact has emboldened some global-warming sceptics who challenge the evidence for man-made climate change and question the need for urgent action, but the IPCC draft does not project any long-term break.
Meanwhile, it forecasts resumption in the warming trend that is likely to cause ever more heat-waves, droughts, floods and rising sea levels.
