I have neither the learning nor the experience to know whether the doomsayers are right about the human causes of climate change. But I am willing to acknowledge that people who know a lot more than I do may be right when they claim that it is the consequence of our own behaviour. I assume that this is why the BBC's coverage of the issue abandoned the pretence of impartiality long ago.

It seems to me that the way to remove people's cynicism is, when asked a straight question, to give a straight answer.

Scepticism is a necessary and vital part of the journalist's toolkit. But when scepticism becomes cynicism it can close off thought and block the search for truth.

The cure for cynicism is simply to engage honestly.

At work people are expected to be at the beck and call of employers all the time. You have blackberries and other things, and they just don't leave you alone. People have less time just to drop into an art gallery.

[Cycling] is easily the quickest way around central London, faster than bus, Tube or taxi. You can predict precisely how long every journey will take, regardless of traffic jams, Tube strikes or leaves on the line. It provides excellent exercise. It does not pollute the atmosphere. It does not clog up the streets.
