Despite the deadly super typhoon that ravaged the Philippines, the World Meteorological Organization, a division of the U.N., said it's been an average year for tropical storms. A total of 86 tropical storms have been recorded this year, three fewer than the annual average since 1981, with Super Typhoon Haiyan one of the most powerful to ever make landfall. "Although individual tropical cyclones cannot be directly attributed to climate change, higher sea levels are already making coastal populations more vulnerable to storm surges. We saw this with tragic consequences in the Philippines," said Michel Jarraud, secretary general of the U.N. weather agency.
