Is climate change turning coastal countries into water worlds?

Imagine you lived in a world of water. Your home is two-feet under. You wade through it, cook on it and sleep above it. This is the reality for hundreds of thousands of people around the world, coastal populations on the front lines of climate change.

Only weeks before world leaders meet in Copenhagen to discuss climate change, NOW senior correspondent Maria Hinojosa travels to Bangladesh to examine some innovative solutions - from floating schools to rice that can "hold its breath" underwater - being implemented in a country where entire communities are inundated by water, battered by cyclones and flooded from their homes.

The Denmark conference can't come soon enough. Scientists project global seas will flood 20 percent of Bangladesh by 2030, stranding some 35 million climate refugees. Some are proposing that industrial nations who contribute to global warming should open their doors to displaced Bangladeshis.

Is a coastal catastrophe approaching, and what should we be doing about it?
