There is a time for weighing evidence and a time for acting. And if there's one thing I've learned throughout my work in finance, government, and conservation, it is to act before problems become too big to manage.

In all my life, I've been trained that when there's a big problem, you run toward it.

Complexity and interconnectedness matter as much as size in assessing risk in banking.

Every global concern - economic, environmental or security-related - can be addressed more effectively when the U.S. and China work together.

I think history shows that countries have to have some kind of a threshold level of economic success before they begin to have the means and the will to focus on the environment.

I've always said to everyone that ever worked for me, if you get too dug in on a position, the facts change, and you don't change to adapt to the facts, you will never be successful.
