We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.
Interpretation
The quote emphasizes the urgent need to combat climate change before it's too late.
Stephen Hawking warns about the potential consequences of climate change, likening Earth to Venus if actions are not taken to reduce carbon emissions. He stresses the urgency of addressing global warming and suggests that waiting for its adverse effects to become apparent could lead to catastrophic consequences.
In practice
In a presentation about environmental issues, one might say: 'As Stephen Hawking pointed out, we need action now to combat climate change.'
We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.
In my opinion, there is no aspect of reality beyond the reach of the human mind.
Strange as it may sound, the power of mathematics rests on its evasion of all unnecessary thought and on its wonderful saving of mental operations.
In the development of antibiotics, the soil microbiological population has contributed more than its share. It is to the soil that the microbiologists came in search of new antibacterial agents.
No one may have the guts to say this, but if we could make better human beings by knowing how to add genes, why shouldn't we?
We need to look at NASA, not as a handout, but as an investment.
It is impossible to devise an experiment without a preconceived idea; devising an experiment, we said, is putting a question; we never conceive a question without an idea which invites an answer. I consider it, therefore, an absolute principle that experiments must always be devised in view of a preconceived idea, no matter if the idea be not very clear nor very well defined.
I think chemistry is being frittered away by the hairsplitting of the organic chemists; we have new compounds discovered, which scarcely differ from the known ones and when discovered are valueless-very illustrations perhaps of their refinements in analysis, but very little aiding the progress of true science.
