“The fifth report of the Intergovernmental Panel on Climate Change, which has taken years to produce and involved hundreds of scientists, was published this morning. It is meant to guide governments in dealing with rising temperatures. “Delegates said the report raised the probability that most global warming was manmade to 95%, from 90% in its previous report in 2007. “The report concludes that many of the observed changes in climate are unprecedented not just over decades but over millennia. It says oceans have warmed, the amounts of snow and ice have diminished, sea levels have risen and concentrations of greenhouse gases have increased. “It found each of the past three decades has been successively warmer at the Earth’s surface than in any preceding decade since 1850.”
“It predicts that by the end of the century, global surface temperatures are likely to increase by at least 1.5C at minimum and over 2C at the higher end. It warns heat waves will occur more frequently and last longer.”
