I'm with the spirit of Earth-Day-yet-to-come. Nobody can really predict the future, all you can do is look at trends, and that could change at any moment.
The Olympics are always a special competition. It is very difficult to predict what will happen.
The best way to predict the future is to invent it.
Nature never rhymes her children, nor makes two men alike. When we see a great man, we fancy a resemblance to some historical person, and predict the sequel of his character and fortune, a result which he is sure to disappoint. None will ever solve the problem of his character according to our prejudice, but only in his high unprecedented way.
You can't really predict the future. All you can do is invent it.

The only way you can predict the future is to build it.
I have no idea what I'm doing when it comes to love. . . There's no pattern to it, except that it happens to all of us, of course. I can't plan for it. I can't predict how it'll end up. Because love is unpredictable and it's frustrating and it's tragic and it's beautiful.

We must prepare students for a future we can neither describe nor predict.
I can predict with some sense of certainty how life will feel in a month. I can with the same logic remember with the same element of reality or truth what life was like a month ago. All perspectives on the past are entirely relative.
A man who drinks too much on occasion is still the same man as he was sober. An alcoholic, a real alcoholic, is not the same man at all. You can't predict anything about him for sure except that he will be someone you never met before.
Even before the election I was saying that the rhetoric used by Trump was going to cause violence before and after the election. That was easy to predict.
I hesitate to predict whether this theory is true. But if the general opinion of Mankind is optimistic then we're in for a period of extreme popularity for science fiction.

Productivity is notoriously difficult to predict.
Geologists and paleo-climatologists know that in the past the Earth's temperature has been substantially warmer than it is today, and that this warming has occurred under purely natural circumstances. Until we can say precisely how much of the current global warming and greenhouse gas increase is the result of this normal temperature cycle, we will not be able to measure how much human activity has added to this natural trend, nor will we be able to predict whether there will be any lasting negative effects.
