CORRESPONDENT Peter Sagar advises (HAS, Sept 16) that on September 20 hundreds of thousands of children will take part in a global warming protest by taking part in strike action.

Until reading Peter's letter I wasn't aware this was being planned.

I do share the concern of the children even though I am not an expert.

However, wouldn't it be better if the children and their guardians moved the strike day to a non-school day – perhaps a Saturday? Cynics might just think they are out for an extended weekend.

Surely they know that the UK authorities are very much aware of the threat of climate change. Will their guardians be subject to fines?

It could be a busy time for the courts or are the schools agreeing with the action?
