The protest is part of the group's Summer Uprising campaign.
Extinction Rebellion activists have blocked a road in central Glasgow to draw attention to the threat of global warming.
The group used a 25ft pink boat to block off the eastbound Trongate between Albion Street and the High Street on Monday.
Activists from the climate change organisation played music and handed flyers to passers-by as part of a five-city “summer uprising” across the UK.
Similar action is being taken in London, Bristol, Cardiff and Leeds as Extinction Rebellion continues its campaign of peaceful protest against climate change.
Susana Hotham, from, Extinction Rebellion Scotland, said: “Climate change is here now and will continue to devastate people all over the world, affecting crop yields and droughts leading to the mass displacement of people.
“Inaction on the part of the government is robbing people all over the world of the human rights we claim to have at the forefront of our ideals.”
In a statement, the group demanded the UK Government take immediate action to halt biodiversity loss and reduce greenhouse gases to net zero by 2025.
A spokesperson said: “Parliament has announced a climate emergency, but the government is not taking the necessary decisive actions required by the crisis. Their 2050 net zero target is an alarmingly insufficient response for halting climate breakdown and biodiversity loss. By then it will be too late.
“Our current ecocidal economic system rewards the exploitation of people and planet. Our house is on fire. Politicians are ignoring the science as they encourage airport expansions, HS2, fracking, oil drilling and exploration while putting billions into new roads and subsidising investment into fossil fuels. Meanwhile, they block onshore wind installations and tax sustainable alternatives, but refuse to put ecocide into law.
“It is only by thinking big, by adopting meaningful measures to reduce carbon emissions to net zero by 2025, protecting biodiversity, and making ecocide law, that the government can show itself to be on the right side of history.”
A large number of police were in attendance at the Glasgow protest. Motorists have been advised to avoid the area if possible.
