Environmental protestors are vowing a daily campaign of ‘civil disobedience’ outside the headquarters of Scotland’s biggest council until politicians and officials declare a ‘climate emergency’.

The group Extinction Rebellion, who recently stormed the debating chamber at the Scottish Parliament, say they will stage sit-ins outside Glasgow City Council in George Square to highlight the threat posed by global warming.

The protests come as hundreds are due to march through the city today in a so called ‘Blue Wave’ - including people dressed as sea creatures - demanding binding policies to reduce carbon emissions to zero by 2025.

Extinction Rebellion, who appear to be growing in number with editions appearing up and down the country, formed around the UK last year to campaign for action on the environment. They also support school climate strikes.

They also want to see the creation of a ‘Scottish Citizens’ Assembly’ to oversee the changes to climate change policy. They are pledged to non-violent civil disobedience, saying that it is citizens’ duty to force their government to step up action.

Group member Daryl Tayar said: “We’re gathering here right outside the City Chambers in George Square in Glasgow at lunchtimes to share our fear, our grief and our determination as we face climate crisis, species extinction and global injustice.’

“This morning we had a ‘Picnic at the End of the World’ right outside the main entrance of the City Chambers to remind Councillors that we are facing an imminent climate crisis with the danger of food shortages and serious flooding here in Glasgow.

“There’s no time left - it’s up to the ordinary people of Glasgow to get out there today and express our anxiety, our frustration and our anger, as well as our care for this planet on which the health and happiness of all human beings depends.”

He added: “We’ll keep doing this until we’re moved away by the police. And then we’ll just take up residence in George Square.

Today’s, which begins at the Clydeside Ampitheatre from Noon, will see people of all ages will form a ‘blue wave’ to represent the rising sea-levels and flooding caused by the rise in global temperatures.

Participants will dress in blues and greens to highlight the wave of water which threatens cities around the world if sea levels keep rising.

The event will be feature music, performance, and free food. Glasgow Poet Laureate, Jim Carruth, will read a poem especially composed for the event, at the start of the march.

In the UK, 29 local authorities have declared a climate emergency, but so far none in Scotland have followed suit.

The peaceful protest will take place following one of the warmest weeks of winter on record - with temperatures reaching almost 20 degrees in February

Extinction Rebellion have staged a number of protests since the start of the year, including interrupting a meeting of the Glasgow City Council Environment, Sustainability and Carbon Reduction City Policy Committee last month

In his speech, member Guy Bowen told the meeting: “This great city is going to be underwater within a generation. We demand that you walk out of this meeting today and tell the residents of Glasgow in plain language of the grave dangers we all share, with the uncontrollable and inevitable impending crises that we are accelerating towards.”

A spokesman for the group said: “Summer 2018 was the warmest summer ever recorded in the UK. Glasgow recorded its hottest day since records began on Thursday June 28, reaching 31.9 degrees Celsius. This caused the roof lining of the Science Centre to melt, and some city railway lines to buckle and signalling systems to fail.Last year’s publicly-funded Climate Ready Clyde key findings report tells us what further climate breakdown will mean for Glasgow: floods, storms, failing infrastructure and displaced people.

“Winter rainfall could rise by 50 per cent by 2080.

“The M74 and M8 motorways will be under water, the tracks and bridges of the West Highland Rail Line will be damaged by coastal erosion, and the Erskine Bridge will be battered by gales.”

He added: “Projections show that the poorest neighbourhoods, in north and east glasgow, will be hit the hardest.

“The financial costs of building flood defences and new infrastructure in response to climate change are an estimated £400 million. “At the moment, our local authorities are only thinking about reacting to climate change, rather than taking immediate, far-reaching action to limit catastrophe.”

A council spokeswoman said: “Glasgow continues to make significant progress in this area having exceeded our emissions reduction target for 2020, ahead of schedule.

“We also recently established a Climate Emergency Working Group in recognition of the gravity of the situation facing the world in the age of climate change.

“To mitigate the impact of climate change, we are aiming to become a carbon neutral city by 2037 and as part of a wide ranging remit, the Group, will look at what needs to be done to meet this commitment, but also how the 2037 target could be brought forward.”
