London - Police in London have arrested 135 anti-climate change activists, police said in a statement on Monday.
This comes as Extensions Republic has launched two weeks of peaceful civil disobedience to call for urgent government action to reduce carbon emissions.
Pictures circulated showed activists blocking a bridge and several roads, as protests spread.
Earlier on Saturday, London police said they had arrested 10 activists claiming to fight climate change before a new wave of protests.
In addition, Extensions Republion organized an 11-day protest in London last April, which affected public transport and roads in the city.
On Thursday, anti-climate change activists used a fire truck to spray red paint on the front of the British Treasury in an attempt to draw attention to what they say is the government's failure to stave off a climate catastrophe.
