Would you bet your paycheck on a weather forecast for tomorrow? If not, then why should this country bet billions on global warming predictions that have even less foundation?

To some extent I happily don’t know what I’m doing. I feel that it’s an artist’s responsibility to trust that.

Being on tour is like being in limbo. It’s like going from nowhere to nowhere.

As I’m traveling around, I meet many small children. And when I look at a small and think how we’ve harmed this beautiful planet since I was that age, I feel a kind of desperation, anger, shame. I don’t know what I feel; I just don’t know what the emotion is.

There is nothing makes a man suspect much, more than to know little.

The main message we want to get out there is that climate change is caused by the rotten economic system.

I used to get the feeling, and sometimes I still get it, that sometimes I was fooling somebody; I don’t know who or what, maybe myself.

Fortune brings in some boats that are not steered.

I don’t know what ‚normal‘ means, anyway.

We are afraid to care too much, for fear that the other person does not care at all.

You never know with these things when you’re trying something new what can happen. This is all experimental.

The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd.

Some scientists believe climate change is the cause of unprecedented melting of the North Pole, and that effects these very uncertain weather patterns. I think we should listen to those scientists and experts.

The symbolism of the climate strike is that if you adults don’t give a damn about my future, I won’t either.

I’m not a fortune-teller.

The natural cause of the human mind is certainly from credulity to skepticism.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

This suspense is terrible. I hope it will last.

Life is a constant oscillation between the sharp horns of dilemmas.

Nothing fortifies scepticism more than the fact that there are some who are not sceptics; if all were so, they would be wrong.

I do not believe any of the statistical claims that are made about public opinion. I don’t see why anybody does.

I don’t know where I’m going from here, but I promise it won’t be boring.

You could warm Mars up, over time, with greenhouse gases.

First, how do we give everyone a fair shot at opportunity and security in this new economy? Second, how do we make technology work for us, and not against us – especially when it comes to solving urgent challenges like climate change? Third, how do we keep America safe and lead the world without becoming its policeman?

The greatest achievements of the human mind are generally received with distrust.

I have written too much history to have faith in it; and if anyone thinks I’m wrong, I am inclined to agree with him.

Risk comes from not knowing what you’re doing.

The most distressing thing that can happen to a prophet is to be proved wrong. The next most distressing thing is to be proved right.

Doubt is not a pleasant condition, but certainty is absurd.

I’m skeptical of any mission that has advertisers at its centerpiece.

If burning fossil fuels was so bad that it threatened our very existence, how could we just continue like before? Why were there no restrictions? Why wasn’t it made illegal? To me, that did not add up.

You know, people talk about this being an uncertain time. You know, all time is uncertain. I mean, it was uncertain back in – in 2007, we just didn’t know it was uncertain. It was – uncertain on September 10th, 2001. It was uncertain on October 18th, 1987, you just didn’t know it.

I spent a lot of years trying to outrun or outsmart vulnerability by making things certain and definite, black and white, good and bad. My inability to lean into the discomfort of vulnerability limited the fullness of those important experiences that are wrought with uncertainty: Love, belonging, trust, joy, and creativity to name a few.

Now, we put out a lot of carbon dioxide every year, over 26 billion tons. For each American, it’s about 20 tons. For people in poor countries, it’s less than one ton. It’s an average of about five tons for everyone on the planet. And, somehow, we have to make changes that will bring that down to zero.

Why should I be studying for a future that soon may not exist?

There is a time for departure even when there’s no certain place to go.

We are living in the beginning of a mass extinction and our climate is breaking down.

Indecision may or may not be my problem.

You can’t learn in school what the world is going to do next year.

Premature certainty is the enemy of the truth.

If you can look into the seeds of time, and say which grain will grow and which will not, speak then unto me.

It is not scientifically possible to accurately predict the outcome of an action. To suggest otherwise runs contrary to historical experience and the nature of war.

If you only do things where you know the answer in advance, your company goes away.

The uncertainty of parenting can bring up feelings in us that range from frustration to terror.

Climate change is a terrible problem, and it absolutely needs to be solved. It deserves to be a huge priority.

What is this world that is hastening me toward I know not what, viewing me with contempt?

If there’s one thing that’s certain in business, it’s uncertainty.

I’ve grown accustomed to hotels and drastic climate change.

At first when I heard about climate change, I was a climate denier. I didn’t think it was happening. Because if there really was an existential crisis like that, that would threaten our civilisation, we wouldn’t be focusing on anything else. That would be our first priority. So I didn’t understand how that added up.

I’m a spokesman for myself. It just so happens that there’s a bunch of people that are concerned with what I have to say. I find that frightening at times because I’m just as confused as most people. I don’t have the answers for anything.

Every possession and every happiness is but lent by chance for an uncertain time, and may therefore be demanded back the next hour.

I think my message to the politicians who have within their power the ability to make change is, ‚Do you really, really not care about the future of your great-grandchildren? Because if we let the world continue to be destroyed the way we are now, what’s the world going to be like for your great-grandchildren?‘

I’m a radical environmentalist; I think the sooner we asphyxiate in our own filth, the better. The world will do better without us. Maybe some fuzzy animals will go with us, but there’ll be plenty of other animals, and they’ll be back.

Life’s short. Anything could happen, and it usually does, so there is no point in sitting around thinking about all the ifs, ands and buts.

I talk to fashion designers and say I want some money to save the rainforest, and they say, ‚Oh, I agree with you completely Vivienne. Yes, climate change, it’s definitely happening,‘ but they don’t feel that they can do anything about it; they don’t even think ‚Well let’s stop it!‘

It is dangerous to be right in matters on which the established authorities are wrong.

No man ever quite believes in any other man. One may believe in an idea absolutely, but not in a man.

We misjudge risk if we feel we have some control over it, even if it’s an illusory sense of control.

Prepare for the unknown by studying how others in the past have coped with the unforeseeable and the unpredictable.

Remember that life’s big changes rarely give advance warning.

I want to marry Arline because I love her – which means I want to take care of her. That is all there is to it. I want to take care of her. I am anxious for the responsibilities and uncertainties of taking care of the girl I love.
