I don't agree with the very destructive methods that these protesters use but, as Monica says, calling these women "silly old biddies" is uncalled for.
As to the comments about whether they use mobile phones, etc., and labelling them as hypocrites if they do, I think that is equally daft. It is very difficult to operate in this world now without a mobile phone or a computer. Virtually everything is based on some device or other. Anyway, we don't know how they conduct their lives - they may well try to make as little environmental impact as possible in their everyday lives.
For anyone who has seen the film "Don't Look Up", although its premise is based on, I think, a missile hurtling towards earth which will destroy it, I think it was a very good metaphor for what is happening re climate change. People who could see the imminent danger the world was facing were given little spots on news programme, in between publicising books, films, and TV programmes, to try and warn everyone that something very dangerous was approaching fast. The end of the film was not optimistic!
