Nigel Calder quotes:

But, when tales of the cosmos are told, this period of ours may always be recalled as that in which men first came to realise what a violent universe we inhabit.

Governments are trying to achieve unanimity by stifling any scientist who disagrees. Einstein could not have got funding under the present system.

The big discoveries raise questions that make astronomers work feverishly and argue with an agitation that verges on rudeness.

The natural pattern of current astronomy is provided by the cryptic unity of nature itself (belief in which is the chief act of faith of the scientist).

It's likely that CO2 has some warming effect, but real proof of that hypothesis is tricky. You have to confirm by observation exactly how the CO2 changes the situation at different altitudes in the atmosphere and in different regions of the world. For example, CO2 is supposed to warm the upper air faster than the surface, but the measurements don't show that happening. When the CO2 effect is eventually pinned down, it will probably turn out to be weaker and much less worrisome than predicted by the global warming theorists.

Recent studies have considered the detection of a spaceship visiting our parish of the galaxy. In my opinion that last thought should bring a blush to every human cheek... Fecklessness might be the main theme of the aliens' report on the new-found source of radio pollution ... that emanates from beings who have mastered a lot of physics, chemistry and biology and yet let their children starve-while all around their planet the energy of their mother star runs to waste in a desert of space.

The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind.
