By EDITH M. LEDERERUNITED NATIONS (AP) â¿¿ The world economy grew at a significantly weaker pace in 2012 and is not likely to pick up enough in the next two years to recover jobs lost during the global financial crisis, the United Nations said Tuesday. The U.N.'s report on the World Economic Situation and Prospects 2013 said that with existing policies and growth trends it may take at least another five years for Europe and the United States to make up for the job losses caused by the 2008-2009 recession. According to the report, world economic growth is expected to reach just 2.2 percent in 2012 â¿¿ a drop from the 2.5 percent predicted in June â¿¿ and is forecast to remain "well below potential" at 2.4 percent in 2013 and 3.2 percent in 2014. "Weaknesses in the major developed economies are at the root of continued global economic woes," the report said. Rob Vos, the U.N.'s team leader for the report, warned that "a worsening of the euro area crisis, the 'fiscal cliff' in the United States and a hard landing in China could cause a new global recession." "Each of these risks could cause global output losses of between 1 and 3 percent," he said. The report said the U.S. economy "weakened notably" during 2012 and growth prospects for 2013 and 2014 remain sluggish. The "already anemic pace of 2.1 percent in 2012" is forecast to drop to 1.7 percent in 2013, and then rise to 2.7 percent in 2014. Several European economies and the euro zone as a whole are already in recession, and unemployment in the euro zone increased to a record high of almost 12 percent this year, the report said. The U.N. said output in Germany, Europe's largest economy, has slowed significantly while France's economy is stagnating.
