At the United Nations Climate Conference in Bali this week more than 2-hundred leading scientists issued a warning. They say that if immediate action is not taken, millions of people will be at risk from extreme events such as heat waves and floods. Here in California scientists say that as the climate warms and polar ice melts, coastal sea levels could easily rise by another three feet by the end of this century. That would have a dramatic impact on San Francisco Bay, as Craig Miller reports.
