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.

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.

What do we expect the climate to do? How will it affect people? And how can we protect people from hardship? We should be willing to face the facts that things may not go very well.

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.

We have to have more consideration for people who have lesser means than we do. It is a problem of survival.

Fresh water is like a fossil fuel; we should not waste it.

The amount of water on the planet does not change, only its quality.
