Clive James: Chris Rock proved satirical comedy is at its strongest when anger is expressed through reason

For all I know, in order to act like Leonardo DiCaprio you have to believe you are 'fighting climate change' when you fly by private jet

Two weeks ago I wrote half a line hinting at my belief - no doubt senile and irrational - that the allegedly forthcoming global climate change disaster might still be up for discussion. Hundreds of objectors immediately surfaced through the web, many of them trolls. If I were out to count the percentage of violently angry people among the internet population, it would be easier than fishing with grenades.

Several of these choleric experts correctly accused me of not being a scientist. My only field of expertise is the use and abuse of language; but a trained ear for empty rhetoric is what tells me that most of them aren't scientists, either. People who call carbon dioxide "carbon" know even less about science than I do. Their anger, I suspect, is driven by belief rather than knowledge.
