I got this from GREN:
"THE WAVE is the march organised by Stop Climate Chaos in London on 5 December, just before the UN Climate Negotiations in Copenhagen.
Join GREN for the Climate Emergency Rally, midday at Speaker’s Corner, and with campaigners from over 100 other organisations across the UK to march to encircle Parliament for the mass ‘Mexican Wave’!
GREN is encouraging people from Reading to go to the march and rally:
-- By train – meet at the front entrance to Reading a station 10.15 a.m. to catch the 10.33 a.m. train to Paddington from where we will go to Speakers Corner, Hyde Park for the midday rally. From there we will join THE WAVE march which leaves Grosvenor Square at 1 p.m. Please bring banners and other things to brighten up the event! See www.gren.org.uk
-- CAFOD have a few places on their coach which is leaving Reading Station at 8am and Woodley at 8:45am. They will then go to an Ecumenical Service at Westminster Methodist Central Hall at 11am before attending THE WAVE. To book a seat contact Rob White -- email@example.com -- and I will put you in touch
For more details, including the route for THE WAVE see www.stopclimatechaos.org
Dress code: Blue! Please bring blue gloves if you have them, or paint your hands blue for the 3pm climax!"
