While President Bush likes to project an image of strength and courage, the real truth is that in the presence of his large financial contributors, he is a moral coward.Collection: Strength
A zebra does not change its spots.Collection: Change
Consider what kind of car you get. Buy cars and other products that have the least impact environmentally.Collection: Car
Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.Collection: Imagination

Airplane travel is nature's way of making you look like your passport photo.Collection: Nature
The ability of big money to shape perceptions - where you have four anti-climate lobbyists for every single member of the House and Senate - is a big factor.Collection: Money
As I have said for many years throughout this land, we're borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the future of human civilization. Every bit of that has to change.Collection: Future

Our democracy, our constitutional framework is really a kind of software for harnessing the creativity and political imagination for all of our people. The American democratic system was an early political version of Napster.Collection: Imagination
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.
You know the old saying: you win some, you lose some... and then there's that little-known third category.
In digital era, privacy must be a priority. Is it just me, or is secret blanket surveillance obscenely outrageous?
No matter how hard the loss, defeat might serve as well as victory to shake the soul and let the glory out.
I think it's harder for people than it should be. But as more and more of us become carbon neutral and change the patterns in our lives to be part of the solution instead of part of the problem, we are now beginning to see the changes in policy that are needed.
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.
I drive a hybrid, and we've changed our light bulbs and windows and installed solar panels and geothermal ground source heat pumps and most everything else.
If you want your energy bills to go up, you should support an ever greater dependence on foreign oil, because the rate of new discoveries is declining as demand in China and India is growing, and the price of oil and thus the price of coal will go sky high.
Today we're dumping 70 million tons of global-warming pollution into the environment, and tomorrow we will dump more, and there is no effective worldwide response. Until we start sharply reducing global-warming pollution, I will feel that I have failed.
As president, I will bring all the parties and stakeholders together. I am going to come up with a solution that respects the environment and does not cause an upheaval in the economy.
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 Bush-Cheney administration had betrayed some basic American values. So there was hunger for change.
We're all capable of mistakes, but I do not care to enlighten you on the mistakes we may or may not have made.
I remember as a boy when the conversation on civil rights was won in the South. I remember a time when one of my friends made a racist joke and another said, 'Hey man, we don't go for that anymore.'
I pledge to you today that as president, in my first budget, I will introduce the largest increase in special education ever.
CO2 is the exhaling breath of our civilization, literally... Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past.
Population growth is straining the Earth's resources to the breaking point, and educating girls is the single most important factor in stabilizing that. That, plus helping women gain political and economic power and safeguarding their reproductive rights.
Consider a clock thermostat, and set it so that you're not using energy when you don't need it, when you're out of your house.
I think George W. Bush has a warm, engaging personality. But, you know, the presidency is more than just a popularity contest.
I have always been fascinated with those who try to look over the horizon and see things that are coming at us.
The heart of the security agenda is protecting lives - and we now know that the number of people who will die of AIDS in the first decade of the 21st Century will rival the number that died in all the wars in all the decades of the 20th century.
I did very extensive diligence on Al Jazeera English, the network from which Al Jazeera America is going to be derived, and it's really very clear that they have long since established a reputation for excellence and integrity and objectivity.
Iraq's search for weapons of mass destruction has proven impossible to deter and we should assume that it will continue for as long as Saddam is in power.
I do genuinely believe that the political system is not linear. When it reaches a tipping point fashioned by a critical mass of opinion, the slow pace of change we're used to will no longer be the norm. I see a lot of signs every day that we're moving closer and closer to that tipping point.
