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.

In this quest to seek and find God in all things, there is still an area of uncertainty. There must be. If a person says that he met God with total certainty and is not touched by a margin of uncertainty, then this is not good.

Our need for certainty in an endeavor as uncertain as raising children makes explicit ‚how-to-parent‘ strategies both seductive and dangerous.

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?

I don’t like to commit myself about heaven and hell – you see, I have friends in both places.

Either he’s dead or my watch has stopped.

Nothing in life is promised except death.

Life is anything but predictable.

No one can possibly know what is about to happen: it is happening, each time, for the first time, for the only time.

We fear that this moment will end, that we won’t get what we need, that we will lose what we love, or that we will not be safe. Often, our biggest fear is the knowledge that one day our bodies will cease functioning. So even when we are surrounded by all the conditions for happiness, our joy is not complete.

It felt like I was the only one who cared about the climate and the ecological crisis. My parents didn’t care about it, my classmates didn’t care about it, my relatives didn’t care about this. I mean nobody I knew cared about this and I felt like I was the only one.

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

I think that when we know that we actually do live in uncertainty, then we ought to admit it; it is of great value to realize that we do not know the answers to different questions. This attitude of mind – this attitude of uncertainty – is vital to the scientist, and it is this attitude of mind which the student must first acquire.

I think that once you fully understand the climate and ecological emergencies, then you know what you can do as well. And, of course, there’s a lot of things you can do in your everyday life, but we cannot be focusing on these individual things you can do. We have to see the full picture.

America is not nearly done. We’re only in the beginning. Who knows who we will be? Who knows… what color we will be? It is all something that, maybe, our descendants – if they survive that long – will see.

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.

Life is a gamble. You can get hurt, but people die in plane crashes, lose their arms and legs in car accidents; people die every day. Same with fighters: some die, some get hurt, some go on. You just don’t let yourself believe it will happen to you.

One can never know for sure what a deserted area looks like.

Faith keeps many doubts in her pay. If I could not doubt, I should not believe.

I think there are more politicians in favor of electric cars than against. There are still some that are against, and I think the reasoning for that varies depending on the person, but in some cases, they just don’t believe in climate change – they think oil will last forever.

Earth might one day soon resemble the planet Venus.

A question that sometimes drives me hazy: am I or are the others crazy?

You should be attacking the carbon emissions, period, and whether it’s cap-and-trade or carbon tax or whatever, that’s the realm in which we should be playing.

And no, we don’t know where it will lead. We just know there’s something much bigger than any of us here.

Gujarat is the fourth state in the world where we have a separate climate-change department.

It’s so hard to know what to do when one wishes earnestly to do right.

Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man’s struggle for good and evil seems inadequate.

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

In such a porcelain life, one likes to be sure that all is well lest one stumble upon one’s hopes in a pile of broken crockery.

If you aren’t in the moment, you are either looking forward to uncertainty, or back to pain and regret.

Knowledge is knowing that we cannot know.

There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.

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

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

Waking up every day and loving someone who may or may not love us back, whose safety we can’t ensure, who may stay in our lives or may leave without a moment’s notice, who may be loyal to the day they die or betray us tomorrow – that’s vulnerability.

The more I see the less I know for sure.

Our economic system, run for profit and waste and based primarily on the extractive industries, is the cause of climate change. We have wasted the earth’s treasure and we can no longer exploit it cheaply.

We’re running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere… can handle before there is an environmental catastrophe.

I mean, people aren’t continuing like this and not doing anything because they are evil, or because they don’t want to. We aren’t destroying the biosphere because we are selfish. We are doing it simply because we are unaware.

Though men determine, the gods doo dispose: and oft times many things fall out betweene the cup and the lip.

I cannot discover that anyone knows enough to say definitely what is and what is not possible.

‚In Utero‘ was the first time I’d made an album that reached into the dark side. I remember the conflict and the uncertainty. I remember all those things when I hear ‚Pennyroyal Tea.‘

Indecision may or may not be my problem.

Using e-mail, I can communicate with scientists all over the world.

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

Everything can change at any moment, suddenly and forever.

I don’t think you ever really know what all you’re doing, so you have to act on faith.

There are plenty of dead scientists I admire, but I can’t think of any living ones. This is probably because it is only in retrospect that one can see who made the important contributions.

Change is always tough. Even for those who see themselves as agents of change, the process of starting a new thing can cause times of disorientation, uncertainty and insecurity.

The reason we should do a carbon tax is because it’s the right thing to do. It’s economics 101, elementary stuff.

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

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.

Often, I can scarcely hear any one speaking to me; the tones yes, but not the actual words; yet as soon as any one shouts, it is unbearable. What will come of all this, heaven only knows!

There are too many accidents that can befall life on a single planet.

It’s hard to speculate what tomorrow may bring.

Scientists have become the bearers of the torch of discovery in our quest for knowledge.

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.

We need every person on Earth to acknowledge that climate change is real and encourage each other and our leaders to address the challenge.

The action we take and the decisions we make in this decade will have consequences far into this century. If America shows weakness and uncertainty, the world will drift toward tragedy. That will not happen on my watch.

Today’s scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

If a man will begin with certainties, he shall end in doubts, but if he will content to begin with doubts, he shall end in certainties.
