RE the debate about climate change. Some people are apparently of the view that the planet is in reasonable health and that fears about climate change, etc, are groundless, if not actual scaremongering.

The inevitable corollary of that view is – since human activity has been by far the biggest factor affecting the planet during the past 200 years – that such activity has been consistently moderate, restrained and responsible.

If, however, you regard such a conclusion as an insult to our intelligence, and recognise that human treatment of the planet has been a spectacularly horrible catalogue of abuse, excess and waste, you are driven inexorably to the conclusion that the planet is in immediate and present danger.

We would do well, therefore, to heed the so-called prophets of doom. We ignore or belittle their message at our peril.
