US teen youngest to climb seven summits

US teenager Jordan Romero has become the youngest person in the world to successfully climb to the summit of the seven tallest mountains in seven continents. Romero, 15, called his mother, Leigh Ann Drake, on Dec 24 to confirm that he had achieved his goal of reaching the top of Mt Vinson Massif in Antarctica. The California native beat the record previously held by British climber George Atkinson, who completed the ascents at age 16 in May. Romero completed the climbs with his father and stepmother. He reached the summit of Mt Everest on May 22, 2010.
