The number of tall buildings completed around the world declined in 2012, according to the Council on Tall Buildings and Urban Habitat. Only 66 skyscrapers more than 656 feet tall were built last year, down from the 82 finished in 2011. The U.S. completed only two buildings. "As 2012 closes, the industry is on the cusp of another burst of tall building development," the report said. "It is likely the 2013 completion total will set a new record for tall building completions, surpassing the 2011 total."
