We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.

We're running out of time.

Imagine a giant asteroid on a direct collision course with Earth. That is the equivalent of what we face now with climate change, yet we dither.

We are on the precipice of climate system tipping points beyond which there is no redemption.

It would be immoral to leave young people with a climate system spiraling out of control.

Global warming has already triggered a sea level rise that could reach from 6 metres (19.69 ft) to 25 metres (27.34 yards).

What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.

How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree... We don't have much time left.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.

We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions.

Nothing is more responsible for the good old days than a bad memory.

My silence doesn't mean I don't know what goes around me, but what goes around me don't deserve my words.

Stupidity-The top of the list for Satanic Sins.

There is no defense against a perfect pass. I can throw the perfect pass.

The Lord shall have made his American Israel high above all nations which he hath made.

The leaders of the future will be those who dare to claim their irrelevance in the contemporary world as a divine vocation.

Usually I commit to something in my head and then I start drawing.

In books, you always know what's coming next. There are no surprises.

The power of the Latin classic is in character , that of the Greek is in beauty . Now character is capable of being taught, learnt, and assimilated: beauty hardly.

Memory works according to meaning, and when something is important to you, the Google in your brain brings it forward all of a sudden.
