There is no way that we can predict the weather six months ahead beyond giving the seasonal average.

There is a very real danger that we will kill everything on this planet now that we have the technological power to do so.

One can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available.

Intelligence is the ability to adapt to change.

The laws of science do not distinguish between the past and the future.

We think we have solved the mystery of creation. Maybe we should patent the universe and charge everyone royalties for their existence.

We won't know for a few years.
