I'm not a specialist in the science but I have followed it fairly closely and it seems to me that there is… — Martin Rees Copy Share Image
The 'clean energy' challenge deserves a commitment akin to the Manhattan project or the Apollo moon landing. — Martin Rees Copy Share Image
We do not fully understand the consequences of rising populations and increasing energy consumption on the interwoven fabric of atmosphere, water, land… — Martin Rees Copy Share Image
I think all countries need to aim to cut the CO2 emissions per person, taking account of externalities like imports and exports. — Martin Rees Copy Share Image
Collective human actions are transforming, even ravaging, the biosphere - perhaps irreversibly - through global warming and loss of biodiversity. — Martin Rees Copy Share Image
Whether it is to reduce our carbon-dioxide emissions or to prepare for when the coal and oil run out, we have to… — Martin Rees Copy Share Image
The carbon dioxide concentration in the atmosphere is measured. It's uncontroversial. It's going up. We know that has a tendency to warm… — Martin Rees Copy Share Image
Issues relating to global health and sustainability must stay high on the agenda if we are to cope with an ageing and… — Martin Rees Copy Share Image
It used to be controversial whether smoking caused lung cancer, it used to be controversial whether HIV caused AIDS. Now, there are… — Martin Rees Copy Share Image
The atmospheric CO2 concentration is rising - mainly due to the burning of fossil fuels. It's agreed that this build-up will, in… — Martin Rees Copy Share Image
The scientific community should work as hard as possible to address major issues that affect our everyday lives such as climate change,… — Martin Rees Copy Share Image
Some global hazards are insidious. They stem from pressure on energy supplies, food, water and other natural resources. And they will be… — Martin Rees Copy Share Image
The important point there is that when people talk about a mean temperature rise of say two, three or four degrees that's… — Martin Rees Copy Share Image
The challenge of global warming should stimulate a whole raft of manifestly benign innovations - for conserving energy and generating it by… — Martin Rees Copy Share Image
In the case of climate change, the threat is long-term and diffuse and requires broad international action for the benefit of people… — Martin Rees Copy Share Image
A monkey is unaware that atoms exist. Likewise, our brainpower may not stretch to the deepest aspects of reality. The bedrock nature of space… — Martin Rees Copy Share
When scientists are asked what they are working on, their response is seldom 'Finding the origin of the universe' or 'Seeking to cure cancer.'… — Martin Rees Copy Share
“The Sun contains about a thousand times more mass than Jupiter. If it were cold, gravity would squeeze it a million times denser than… — Martin Rees Copy Share
“We, and the visible universe around us, may exist only because of a difference in the ninth decimal place between the numbers of quarks… — Martin Rees Copy Share
Crucial to science education is hands-on involvement: showing, not just telling; real experiments and field trips and not just 'virtual reality.' — Martin Rees Copy Share
I have no religious belief myself, but I don't think we should fight about it. In particular, I think that we should not rubbish… — Martin Rees Copy Share
“More energy is needed to rise a millimetre above a neutron star's surface than to break completely free of Earth's gravity. A pen dropped… — Martin Rees Copy Share
The next humans to walk on the moon may be Chinese. Only China seems to have the resources, the dirigiste government, and the willingness… — Martin Rees Copy Share
If we ever established contact with intelligent life on another world, there would be barriers to communication. First, they would be many light years… — Martin Rees Copy Share
There is an ever-widening gap between what science allows and what we should actually do. There are many doors science can open that should… — Martin Rees Copy Share
An insect is more complex than a star..and is a far greater challenge to understand. — Martin Rees Copy Share
The physicist is like someone who's watching people playing chess and, after watching a few games, he may have worked out what the moves… — Martin Rees Copy Share
We are 'nuclear waste' from the fuel that makes stars shine; indeed, each of us contains atoms whose provenance can be traced back to… — Martin Rees Copy Share
Just as there are many Jews who keep the Friday ritual in their home despite describing themselves as atheists, I am a 'tribal Christian,'… — Martin Rees Copy Share
