British climate change campaigners ride The Wave

The Wave claims to be 'UK's biggest ever demonstration for urgent action on climate change'. Will you take part – and do marches work?
The breadth and depth of support for the Stop Climate Chaos Coalition is very impressive indeed. Organisations ranging from Greenpeace, Friends of the Earth and WWF through to the Women's Institute, Unison and Unicef are members, as are dozens of others. In fact, the coalition claims to boast more than 11 million people spanning around 100 organisations.
Given its focus on, well, coalescing to stop climate chaos, you would expect it to be ramping up its efforts ahead of the Copenhagen climate summit in a month's time. I have to admit that until today it had escaped my attention, but the coalition has been doing just that by organising the "UK's biggest ever demonstration for urgent action on climate change". At 12pm on December 5, it wants as many of its supporters as possible to meet at Grosvenor Square in London for a three-hour march to Parliament Square (nationwide transport details can be found online).
"Tens of thousands of people from all walks of life will flow through the streets of London to demonstrate their support for a safe climate future for all," say the organisers, who are calling the march The Wave. It's a good name, although has some unfortunate connotations with the fascist cult in the film of the same name, not to mention risk of being drowned out online by Google's new communication tool, Wave.
Today marks the official launch of The Wave website, which is dedicated to drumming up support for the march. As seems the norm these days, a Twitterstorm has been called for between 3pm and 4pm today. Supporters are also urged to send in their own homemade videos of themselves performing a Mexican wave. Together, the videos are being stitched together to form a loop of waves rippling across the homepage. (Is this really the best motif to use? I always thought Mexican waves were viewed as a sign of boredom and indifference by a football crowd?!)
Climate change marches in the UK haven't, to date, pulled in the kind of numbers you might expect to see at, say, an antiwar march.
I'm sure there are multiple reasons for this, but principal among them is probably the underlying lack of desperate urgency many people still feel towards the threat of climate change. It is still largely deemed to be a distant problem, particularly as politicians seem to be fixated with talking about targets for the now mythical year of 2050. Holding a march on a Saturday in December is also, no doubt, another contributing factor.
But if there's ever a time to support just such a march I guess it must be now. Will you be going? What are your experiences of the previous climate change marches that have been held in London in December? And, crucially, does marching make a difference?
