Scientists say nature and man together cooked up the disaster that has devastated parts of the Philippines.
Typhoon Haiyan smacked the island nation with fierce winds and a deadly storm surge. The Philippines sit in the middle of the world's most storm-prone region, which gets some of the biggest typhoons because of vast expanses of warm water that act as fuel.
But meteorologists say humans played a big role in this disaster -- probably bigger than nature's.
Factors in the unfolding tragedy include poverty and a tremendous growth in population, much of it in vulnerable coastal areas with poor construction.
