The full committee met, pursuant to notice, at 9:34 a.m. in room 406, Dirksen Senate Office Building, Hon. Barbara Boxer (chair- man of the full committee) presiding. Present: Senators Boxer, Inhofe, Cardin, Warner, Whitehouse. Also present, Senators Mikulski and Webb. STATEMENT OF HON. BARBARA BOXER, U.S. SENATOR FROM THE STATE OF CALIFORNIA Senator BOXER. We call the Committee to order. We welcome our honored guests. I know that Senator Warner has to go down to the Floor and work on the defense bill. He is going to come back as soon as he possibly can, but in deference to his schedule, I would ask if he would like to make his remarks before Senator Inhofe and I do. Senator WARNER. I thank you, Madam Chairman. Senator BOXER. Certainly. Senator WARNER. Then I shall return to this hearing quite promptly. STATEMENT OF HON. JOHN WARNER, U.S. SENATOR FROM THE COMMONWEALTH OF VIRGINIA Senator WARNER. I am privileged this morning, together with my colleague Senator Webb, to introduce our distinguished Governor, Governor Kaine, who I have worked with now these several years. It has been my privilege in the 29 years I have been in this institu- tion to work with 10 Virginia Governors. I would say that this one is fast achieving the role of being at the top of his class. He has a heartfelt concern about the issues surrounding global climate changes, the mysteries and what is known in this area. He is pro- ceeding to lead our State to take an important position, along with other States I hope, as we begin to go into the world of the un- knowns and try and do what we can at this point in America’s his- tory to hopefully join other nations to achieve a measure of global warming recognition and action. Under your leadership, as you know, Senator Lieberman and I have a bill that will soon come before this Committee. But on this subject, I would like to first mention that it has been my privilege to work on the issues of the Chesapeake Bay for many years. I (1) 2 harken back to two great Senators, Senator Matthias and Senator Paul Sarbanes and I and others who initiated the earliest legisla- tion with regard to the Chesapeake Bay. We went in there with the best of intentions, and laid a foundation legislatively. I think collec- tively the several States that border the Bay have begun to pull their fair share of the load and responsibility, together with the Federal Government, but it has to be a joint project. This magnificent bay is absolutely essential to our ecosystem, and also we must be concerned about a part of the real estate of our great commonwealth, Virginia, which borders the Bay and could be subjected, the Tidewater region, to severe damage if in the future years there is a significant rise in the water levels world- wide. I believe our territory—and the Governor will go into details on this—is one of the lowest of any major city throughout certainly the United States. So we are anxious to hear from Governor Kaine when his time comes, and thank you, Madam Chairman and the Ranking Mem- ber, for allowing me to make a few remarks. I will return as quick- ly as I can.
