Thousands of climate change campaigners took to the streets across the UK and worldwide this weekend to demand concrete action to reduce greenhouse gas emissions.
Marches took place in more than 50 cities globally, including London, Cardiff, Glasgow and Belfast.
Saturday's London march was organised by Stop Climate Chaos coalition member, Campaign Against Climate Change.
Despite wet and cold conditions, over 6,000 people marched with banners and music from Millbank to the US Embassy to demand global action on climate change and a tough UK Climate Bill to reduce carbon emissions by at least 80% by 2050.
A delegation of campaigners, that included a number of children, also delivered a letter to 10 Downing Street urging the Government to secure a UN treaty that prevents dangerous climate change.
Jonathan Essex from the Campaign Against Climate Change said "For the sake of our children and the next generation, we need to live in such a way that those of the next generation can also live."
The rallies come midway through the UN climate talks in Bali where thousands of delegates from almost 200 countries are considering how to cut green house gas emissions after the current Kyoto Protocol targets expire in 2012.
