Climate change is occurring far more rapidly than even the worst predictions of the UN’s Nobel Prize-winning scientific panel on climate change, Al Gore said on Thursday. Recent evidence shows ‘the climate crisis is significantly worse and unfolding more rapidly than those on the pessimistic side of the IPCC projections had warned us,’ climate campaigner and former US vice-president Gore said. There are now forecasts that the North Pole ice caps may disappear entirely during summer months within five years, he told a gathering at the World Economic Forum in Davos. In 2007, the Intergovernmental Panel on Climate Change (IPCC) issued a massive report the size of three phone books on the reality and risks of climate change, its 4th assessment in 18 years. Global warming is a key theme at this year’s meeting of the world’s business and political elite in Davos.
