 An inefficient virus kills its host. A clever virus stays with it. |
| I'm a scientist, not a theologian. I don't know if there is a God or not. Religion requires certainty. |
| We'd never have got a chance to go outside and look at the earth if it hadn't been for space exploration and NASA. |
| Geological change usually takes thousands of years to happen but we are seeing the climate changing not just in our lifetimes but also year by year. |
| I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway. |
| If it hadn't been for the Cold War, neither Russia nor America would have been sending people into space. |
| A billion could live off the earth; 6 billion living as we do is far too many, and you run out of planet in no time. |
| Science always uses metaphor. |
| Just after World War II, this country led the world in science by every way you could measure it, yet the number of scientists was a tiny proportion of what it is now. |
| If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so. |
| The oil companies regard nuclear power as their rival, who will reduce their profits, so they put out a lot of disinformation about nuclear power. |
| Esso has been the main one in America spreading the disinformation that there is no global warming problem. |
| NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station. |
| I've got personal views on the '60s. You can't have freedom without paying the price for it. |
| China will soon emit more greenhouse gases than America, but its regime knows if it caps aspirations there will be a revolution. |
| This programme to stop nuclear by 2020 is just crazy. If there were a nuclear war, and humanity were wiped out, the Earth would breathe a sigh of relief. |
| You mustn't take what I say as gospel because no one can second-guess the future. |
| Let's make hay while it lasts. |
| Florida will be gone altogether, the whole damned place, in not too long. |
| All the modelling we do shows that the climate is poised on the jump up to a new hot state. It is accelerating so fast that you could say that we are already in it. |
