It's official! Climate alarmists are now even more alarmed…

The lack of confidence in the future on the part of what I regard as the pseudo-left is found in the oft-repeated assertion that the planet has reached its natural limits. 'We have gone too far with our so-called progress – the planet cannot sustain it any longer'. I can think of no idea that is more reactionary than this one. It could have been said at any point in history, by any set of princes and popes.

Once upon a time, coal was used merely for ornamental purposes. In Roman times, had you suggested that that black chunk on the end of the local beauty's necklace would power a revolution in industry and production, and in social relations, that would overthrow a future system known as feudalism and lead to secular democracy and capitalism, you would have been regarded as insane. Who knows what the next energy source will be? How dare the reactionaries tell us that the planet's resources are finite!

Those who think that way cannot see beyond solar panels and windmills, let alone begin to consider nuclear fusion or appreciate how northern and central Australia could one day flourish.

And then there are the planets and the stars. Awaiting us.
