You seem to underestimate the active conviction and call for immediate change from young folks..

- 50 years younger than us...

You mean the ones that insist that we drop them off at school and take them everywhere in cars? Or the ones who seem incapable of conversation without hand held electronic devices? Or the ones who must have the latest phone while the old one goes into landfill? Let's compare that to when I was in my teens shall we? Walked to school. Went further afield on the bus. Bought stuff in paper bags. Took bottles back to the shop to get the deposit back. Went to the phone box to call people but only if they happened to have a phone. Need I go on? :-D

As to 'elements from the left'. Just who are these elements? Is support for fixing climate change limited to those on the left of the spectrum? I think not.
