If there are climate talks, then we must be marching. I’ve been coming to the big, annual Campaign Against Climate Change march for years, and it has been exponentially bigger every time. This year’s event on Saturday was no exception.
The focus of CACC is to press for international agreement on effective carbon dioxide emissions cuts. So, with the US holding this up ever since George Bush took power, the American Embassy in Grosvenor Square is always the focus of activities, either starting or ending the march.
This year, we began with a rally in the square. Seize the Day  provided music between speeches from, among others, CACC vice presidents Norman Baker MP, Green MEP Caroline Lucas and writer George Monbiot. George’s speech was the most startling – he warned activists sternly against too much ‘doom and gloom’ in our campaigning.
He pointed out the disturbing fact that erstwhile climate deniers are changing their strategy and attempting to switch from blocking action by pretending there isn’t any problem into blocking action by painting climate change as too far gone to bother. With most sane people now in a mid-position where we recognise the problem at the same time as recognising a lot of really obvious solutions, he argued that we should tone down our rhetoric, be positive and get some action going at last - or we’d be just as culpable for the consequences. Harsh stuff, but it was something fresh we needed to hear.
On the more political side of things, Caroline Lucas warned Tony Blair that the time for delay and fudge was over. She said that failure to negotiate a fair and effective international treaty is morally negligent and called for real UK leadership in negotiations this week at climate talks in Nairobi.
Setting off for Trafalgar Square, I was struck by the vast range of different groups marching together. Along with the familiar CACC greenhouse, Friends of the Earth  flags, a big Green Party  contingent and of course our own Alliance Against Urban 4×4s'  lollipop man, people dedicated to campaigning on individual issues were everywhere.
I tried to emulate John Reed, author of revolutionary epic ‘Ten Days that Shook the World,’ by collecting as many leaflets and postcards as possible and I now have a fine collection of literature from the likes of Plane Stupid, RoadBlock, Group Against Motorway Expansion, Airportwatch, World Naked Bike Ride, Rising Tide, the Vegan Society, Christian Ecology Link, Stop Stansted Expansion, Come Off It, and the DOVE campaign against the Newhaven incinerator (if I missed your group – sorry!)
Also notable was the rising number of political parties in the mix. I saw placards by the Greens, LibDems, Respect, Socialist Workers and even the Bolshevik Tendency being carried, and speakers from the platform at the Embassy also included Zac Goldsmith for the Tories and Labour MPs.
Arriving at Trafalgar Square, all thoughts of party politics were banished, however, as the CACC march joined thousands of people filling the square as part of the Stop Climate Chaos coalition’s ‘I-count’ rally. Groups supporting the coalition are an even more diverse collection than the activists on the march and include the Women’s Institute.
Instinctively piqued at the lack of real political fire coming from the actors, comedians and pop stars on the stage (no politicians were allowed on the bill), I tried to put my feelings aside at the sight of the huge crowd they had brought along to the day’s set of actions, many of whom wouldn’t have felt comfortable with the radical types outside the US Embassy.
Phil Thornhill, the founder of CACC, started this traditional day of action single-handed in 2001 after the USA pulled out of the Kyoto agreement, and it is the sign of a great achievement that this day is now both a mainstream and an international event, adopted by such a wide range of groups and nations.
Forty-eight countries around the world saw demonstrations on Saturday, including 90,000 in Australia and an inaugural event in Taiwan. Maybe soon we’ll see some results.
