Our "leaders" are going to keep making empty promises. It makes them feel good. It gets the activists to act like zombie kittens. If you want to have some self-respect and perhaps make a difference (actual facts may vary), then find a functioning group that cares about your skills and knowledge - what you have, what you want.
One useful group might be www.climateemergencymanchester.net - you can email them on firstname.lastname@example.org
