You see that pale, blue dot? That's us. Everything that has ever happened in all of human history, has happened on that pixel. All the triumphs and all the tragedies, all the wars all the famines, all the major advances... it's our only home. And that is what is at stake, our ability to live on planet Earth, to have a future as a civilization. I believe this is a moral issue, it is your time to seize this issue, it is our time to rise again to secure our future.

As human beings, we are vulnerable to confusing the unprecedented with the improbable. In our everyday experience, if something has never happened before, we are generally safe in assuming it is not going to happen in the future, but the exceptions can kill you and climate change is one of those exceptions.

As long as the government's actions are secret, it cannot be held accountable. A government for the people and by the people should be transparent to the people.

When people flirt with despair about the future, they are less likely to take the actions necessary to safeguard it, focusing instead on the short-term.

There are skeptics who do not come to their view because they have a source of income from carbon polluters.

The message from Wal-Mart today to the rest of the business community is there need not be any conflict between the environment and the economy. We will find the way not only to reconcile (those), but to find new profits and new opportunities as we do the right thing.

As it turns out, the scientific community has been addressing this particular question for some time now and they say that increased heavy snowfalls are completely consistent with what they have been predicting as a consequence of man-made global warming.

The key.. will be a new public awareness of how serious is the threat to the global environment. Those who have a vested interest in the status quo will probably continue to be able to stifle any meaningful change until enough citizens.. are willing to speak out.

Surveillance technologies now available - including the monitoring of virtually all digital information - have advanced to the point where much of the essential apparatus of a police state is already in place.

The global environment crisis is, as we say in Tennessee, real as rain, and I cannot stand the thought of leaving my children with a degraded earth and a diminished future.

What changed in the United States with Hurricane Katrina was a feeling that we have entered a period of consequences.

There is an air of unreality in debating these arcane points when the world is changing in such dramatic ways right in front of our eyes because of global warming.

The insistence on complete certainty about the full details of global warming-the most serious threat we have ever faced-is actually an effort to avoid facing the awful, uncomfortable truth: that we must act boldly, decisively, comprehensively, and quickly, even before we know every last detail about the crisis. Those who continue to argue that the appropriate response is merely additional research are simply seeking to camouflage timidity or protect their vested interest in the status quo.

Two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves and deal with the underlying causes of global warming.

I think that more diversity is a good thing, and fresh points of view articulated by people who are committed to excellence in journalism is a beneficial change in the American media landscape.

In a time of social fragmentation, vulgarity becomes a way of life. To be shocking becomes more important - and often more profitable - than to be civil or creative or truly original.

We the human species, are confronting a planetary emergency-a threat to the survival of our civilization that is gathering ominous and destructive potential...the earth has a fever. And the fever is rising...Indeed, without realizing it, we have begun to wage war on earth itself.

We are close to a time when all of humankind will envision a global agenda that encompasses a kind of Global Marshall Plan to address the causes of poverty and suffering and environmental destruction all over the earth.

We can't negotiate the facts. We can't negotiate the truth about the situation. And for those who are too fearful to finish, it can be done and must be done. Make sure we succeed, . . . It is wrong for this generation to destroy the habitability of our planet and ruin the prospects of every future generation.

When you have the facts on your side, argue the facts. When you have the law on your side, argue the law. When you have neither, holler.

If the only tool we use to analyse what's valuable is a price tag, then those things that don't have price tags begin to look like they have no value.
