We still have hope; it is what keeps us going.

I am involved in making measurements in polar oceans, and they are changing more than anything else. I think we have to be prepared for major changes associated with the melting of floating ice and the melting of the Greenland glacier.

There is no question that a very large number of people have to move; you cannot live where the water comes over you. I have not heard one suggestion on how we are going to move one hundred million people out of low-lying areas and what countries would be willing to accept them.

This is going to be a difficult few hundred years. No matter what we do, we have to give up some of the advantages of the wealthy Western nations and help out people who are less fortunate. That is the key. I think we can do it if we have more compassion for one another.

We still have hope; it is what keeps us going.

People should treat the oceans like we do anything else that we care about - with consideration, with care, and affection. That's it. For that we must educate.

More and more students are playing it safe and not taking any risks. You might not succeed, but that's just part of the game.
