These ice sheets are moving far more rapidly than anybody predicted. It's -- it has really shocked the scientists.

Consensus supporting this view on global warming is as strong as anything in science, with the possible exception of gravity.

My fellow Americans -- people all over the world, we need to solve the climate crisis.

My fellow Americans, people all over the world, we need to solve the climate crisis. It's not a political issue. It's a moral issue.

Global warming is real. We human beings are responsible for the vast majority of it. The results are bad, headed toward catastrophic. We need to fix it. It is not too late.

the time to act is melting away.

If we in this generation, alive right now, decide to continue dumping these enormous quantities of global warming pollution into the earth's atmosphere, in spite of the clear scientific consensus that it is causing a process of destruction…

The issue may be mired in politics and our fossil fuel economy, but it's an issue Al Gore promises he will not let melt away.

We may have as little as 10 years.

The truth is inconvenient for them.

Exactly, to mobilize the base in, you know, Pennsylvania is an important place, particularly the African-American vote there in Philadelphia, probably made a difference for Al Gore four years ago.

He really believes so strongly that this country can be even greater, and that a change of leadership is needed, and he's very excited to see that it seems we really do have a chance to do that this year.

He will reference that, mainly in the context that every vote counts, and also that it really matters who is president, and what's happened in the last four years with this change of administration.

He just felt strongly that this was a poorly planned invasion of Iraq that was really draining resources and attention from fighting the terrorists, the network of al Qaeda.

How dare the incompetent and willful members of this Bush-Cheney administration humiliate our nation and our people in the eyes of the world and in the conscience of our own people? How dare they subject us to such dishonor and disgrace…

the enthusiasm generated by the Dean campaign is the right prescription for America.

Thinking of you, but unable to endorse you, because you pandered too much to the party faithful in the early primaries to be a viable candidate.

How do you say you're sorry for dissing your former running mate?

Howard Dean and you have managed to do a better job of igniting enthusiasm at the grassroots all across the United States of America, and that's what we need to rebuild the Democratic Party.

Howard Dean really is the only candidate who has been able to inspire at the grassroots level all over this country the kind of passion and enthusiasm for democracy and change and transformation of America that we need in this country.

It was a mistake to get us into a quagmire over there. So don't tell me that because Howard Dean was the only major candidate who was right about that war, that that somehow calls his judgment into question on foreign policy.

Get well soon. You blew it in Iowa, but New Hampshire is just around the corner. Pull yourself together, or your shot at the nomination is dead.

A Democratic bombshell: Al Gore will endorse Howard Dean for president.

The people who want to see this recall take place are disrespecting the majority of Californians who voted in the election last year. Disrespecting the right of the majority to engage in self-governance.

George Bush is my president. I support him.
