Door to 2 degree temperature limit is closing: IEA

16 May 2012 (Reuters) – The chance of limiting the rise in global temperatures to 2 degrees Celsius this century is getting slimmer and slimmer, the head of the International Energy Agency warned on Wednesday. “What I see now with existing investments for plants under construction … we are seeing the door for a 2 degree Celsius target about to be closed and closed forever,” Fatih Birol, the IEA’s chief economist, told a Reuters’ Global Energy & Environment Summit. “This door is getting slimmer and slimmer in terms of physical and economic possibility,” he warned. The IEA said last November that around 80 percent of total energy-related carbon emissions permissible by 2035 to limit warming were already accounted for by existing power plants, buildings and factories, leaving little room for more. In 2010, countries agreed that deep emissions cuts had to be made to keep an increase in global average temperature below 2 degrees Celsius above pre-industrial levels this century. Scientists say that crossing the threshold risks an unstable climate in which weather extremes are common but efforts so far to cut greenhouse gas emissions are not seen as sufficient to stop a rise beyond 2 degrees. A report this month by the Club of Rome think tank said rising carbon dioxide emissions will cause a 2 degree rise by 2052 and a 2.8 degree rise by 2080, though some other estimates are more conservative. Some countries are focusing on domestic economic pressures, which could delay climate action and add to the cost of fighting climate change in the long-run. “One dollar not invested now in reducing C02 will cost 4.6 dollars in the next decade to achieve the same effect,” Birol said. A major reason for rising carbon dioxide emissions was fossil fuel subsidies, he added. In 2012, $630 billion was spent on fossil fuel subsidies globally, with half of this from the Middle East and the other half from the rest of the world, Birol said. “By contrast, in 2010, fuel subsidies totalled $400 billion. We are going backwards,” he said. […]
