Experts blame man and nature for Typhoon

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.
