The following remarks are former Vice President Al Gore's prepared testimony before the U.S. House of Representatives Energy and Commerce Committee's Subcommittee on Energy and Air Quality, and the Science and Technology Committee's Subcommittee on Energy and Environment:
Chairman Dingell, Chairman Gordon, Congressman Barton, Congressman Hall and members of the subcommittees. I want to thank you for the gracious invitation to be with you today, giving me an opportunity to return to the House to talk about the climate crisis.
I want to testify today about what I believe is a planetary emergency -- a crisis that threatens the survival of our civilization and the habitability of the Earth. Just six weeks ago, the scientific community, in its strongest statement to date, confirmed that the evidence of warming is "unequivocal." Global warming is real and human activity is the main cause. The consequences are mainly negative and headed toward catastrophic, unless we act. However, the good news is that we can meet this challenge. It is not too late, and we have everything we need to get started.
As many know, the Chinese expression for "crisis" consists of two characters side by side. The first symbol means "danger." The second symbol means "opportunity." I would like to discuss both the danger and the opportunity here today.
First of all, there is no longer any serious debate over the basic points that make up the consensus on global warming. The 10 warmest years on record have all been since 1990. Globally, 2005 was the hottest of all. In the United States, 2006 was the warmest year ever. The winter months of December 2006 through February 2007 make up the warmest winter on record. These rising temperatures have been accompanied by many changes. Hurricanes are getting stronger. Sea levels are rising. Droughts are becoming longer and more intense. Mountain glaciers are receding around the world.
New evidence shows that it may be even worse than we thought. For example, a recent study published by the University of Alaska-Fairbanks indicates that methane is leaking from the Siberian permafrost at five times the predicted levels. Methane is 23 times as potent a greenhouse gas as carbon dioxide and there are billions of tons underneath the permafrost.
However, there is a great deal of new momentum for action to solve the climate crisis. Today, I am here to deliver more than a half million messages to Congress asking for real action on global warming. More than 420 mayors have now adopted Kyoto-style commitments in their cities and have urged strong federal action. The evangelical and faith communities have begun to take the lead, calling for measures to protect God's creation. The State of California, under a Republican governor and a Democratic legislature, passed strong, economy wide legislation mandating cuts in carbon dioxide. Twenty-two states and the District of Columbia have passed renewable energy standards for the electricity sector. Much more needs to be done, but change is in the air.
